All questions

Question 1

Start the norepinephrine infusion and titrate rapidly based on blood pressure readings every 2 minutes
Ask a second licensed nurse to independently verify the norepinephrine concentration, dose in micrograms per minute, and infusion pump settings before initiation (correct answer)
Document the baseline vital signs and then prepare the infusion according to the order
Delegate verification of the medication label and tubing trace to an experienced unlicensed assistive personnel

Explanation: This question tests understanding of high-alert medication protocols and independent double-checks for vasoactive infusions. The critical safety framework requires independent verification of all parameters for vasoactive drugs since errors can cause severe hemodynamic instability. Option B ensures the highest safety standard by having a second licensed nurse independently verify the drug concentration, dose calculation in micrograms per minute, and all pump settings before initiation. Option A starts without verification risking cardiovascular complications, option C documents before preparing which doesn't ensure verification, and option D inappropriately delegates verification to unlicensed personnel. The decision-making principle is that all vasoactive infusions require independent double-checks by licensed nurses to prevent life-threatening blood pressure fluctuations and organ damage. A transferable strategy is to treat all vasoactive medications as ultra-high-alert drugs requiring meticulous two-nurse verification of concentration, dose calculations, and pump programming before any titration begins.

Question 2

A 67-year-old client with a mechanical heart valve is being discharged on a new prescription for warfarin 5 mg by mouth daily. Current medications include amiodarone and omeprazole; incorrect dosing can lead to life-threatening bleeding or thromboembolism. The nurse is preparing to give today's first inpatient dose. Which action should the nurse take FIRST to ensure medication safety?

Provide detailed teaching about dietary vitamin K consistency before verifying today's dose
Have a second licensed nurse independently verify the ordered dose against the most recent international normalized ratio result and the medication label before administration (correct answer)
Administer the medication now and then monitor for bruising and hematuria throughout the shift
Document the planned discharge medication list in the chart before giving the first dose

Explanation: This question tests understanding of high-alert medication protocols and independent double-checks for anticoagulant therapy initiation. The critical safety framework requires independent verification of warfarin dosing against current INR results to prevent bleeding or clotting complications. Option B ensures the highest safety standard by having a second licensed nurse independently verify the ordered dose against the most recent INR result and confirm the medication label matches the order. Option A provides teaching without verification, option C administers without any double-check risking hemorrhage, and option D documents discharge planning before ensuring today's dose is safe. The decision-making principle is that warfarin requires independent verification of dose appropriateness based on current INR values, especially when initiating therapy or with concurrent interacting medications like amiodarone. A transferable strategy is to always verify warfarin doses against current INR results with independent double-checks, recognizing that drug interactions can significantly affect warfarin's anticoagulant effect.

Question 3

A 58-year-old client with type 2 diabetes mellitus is admitted for pneumonia and is now prescribed a new order for subcutaneous insulin glargine 24 units at 2100; current medications include metformin and prednisone. Because insulin is a high-alert medication, which step is ESSENTIAL before administering this medication?

Administer the insulin as ordered and then monitor blood glucose every 4 hours for hypoglycemia
Document the medication administration in the electronic record before giving the injection to avoid omission
Ask another licensed nurse to independently verify the insulin type and dose against the order and the prepared syringe or pen before administration (correct answer)
Have the nursing assistant confirm the dose on the insulin label while the nurse prepares the injection

Explanation: This question tests understanding of high-alert medication protocols and independent double-checks. The critical safety framework involves independent verification and high-alert medication protocols for insulin to prevent dosing errors. Asking another licensed nurse to independently verify the insulin type and dose against the order and prepared syringe or pen ensures the highest safety standard by reducing the risk of administering the wrong type or amount, which could lead to severe hypoglycemia. Administering without verification, documenting before giving, or having a nursing assistant confirm neglects the required independent licensed nurse check, increasing error risk; monitoring afterward does not prevent initial errors. The decision-making principle in medication safety emphasizes double verification for high-alert drugs like insulin to catch potential mistakes before they reach the patient. Adherence to this protocol is crucial as insulin errors can cause life-threatening hypo- or hyperglycemia. A transferable strategy is to always perform an independent double-check with another RN for all high-alert medications, confirming order, drug, dose, and client identifiers.

Question 4

A 72-year-old client with chronic kidney disease stage 4 (estimated glomerular filtration rate 22 mL/min/1.73 m²) is hospitalized for atrial fibrillation with rapid ventricular response and has an order for intravenous heparin infusion using the facility protocol; current medications include lisinopril and furosemide. Heparin is a high-alert medication with significant bleeding risk if misdosed. What is the nurse's PRIORITY action before medication administration?

Initiate the infusion and plan to recheck activated partial thromboplastin time after 6 hours
Obtain an independent double-check with another licensed nurse of the concentration, pump settings, and initial rate per protocol before starting the infusion (correct answer)
Document the heparin start time and infusion rate in the electronic record before connecting the tubing to the client
Ask the unit clerk to verify that the correct heparin bag was delivered from the pharmacy

Explanation: This question tests understanding of high-alert medication protocols and independent double-checks. The critical safety framework involves independent verification and high-alert medication protocols for heparin infusions to mitigate bleeding risks. Obtaining an independent double-check with another licensed nurse of the concentration, pump settings, and initial rate per protocol ensures the highest safety standard by preventing programming or concentration errors that could lead to overdose or underdose. Initiating without verification, documenting before connecting, or asking a unit clerk to verify neglects the licensed nurse independent check, heightening risk of fatal errors; rechecking labs later does not avert initial mistakes. The decision-making principle in medication safety prioritizes pre-administration verification for infusions to ensure accuracy. Adherence to protocol is essential as heparin can cause severe bleeding if misdosed, especially in renal impairment. A transferable strategy is to routinely involve a second RN for independent verification of all high-alert infusion setups before starting.

Question 5

A 49-year-old client is admitted with acute coronary syndrome and has an order for intravenous alteplase per protocol; current medications include heparin and aspirin. Thrombolytics are high-alert because dosing errors can cause catastrophic bleeding. Which action should the nurse take FIRST to ensure medication safety?

Start the infusion and monitor neurologic status and bleeding frequently
Have another licensed nurse independently verify the client's weight-based dose, medication reconstitution, and infusion pump settings before administration (correct answer)
Document baseline vital signs and then prepare the medication without a second check
Ask a nursing assistant to obtain the client's weight from the chart to support dosing

Question 6

A 69-year-old client with type 2 diabetes mellitus and acute kidney injury is ordered an intravenous regular insulin infusion for diabetic ketoacidosis using the facility protocol; current medications include no home diabetes medications during hospitalization. Insulin infusions are high-alert due to rapid onset and severe hypoglycemia risk if the rate is incorrect. The nurse should QUESTION which part of the medication administration process?

The nurse asks a second licensed nurse to independently verify the insulin concentration and infusion pump settings before starting
The nurse starts the infusion after programming the pump based on the protocol without an independent double-check (correct answer)
The nurse confirms the most recent blood glucose and potassium level before initiating the infusion
The nurse plans for frequent blood glucose monitoring per protocol after initiation

Explanation: This question tests understanding of high-alert medication protocols and independent double-checks. The critical safety framework involves independent verification and high-alert medication protocols for insulin infusions to avoid hypoglycemia. The nurse should question starting the infusion without an independent double-check because it bypasses the highest safety standard, risking programming errors. Verifying with another RN, confirming labs, or planning monitoring are appropriate but not the part to question. The decision-making principle in medication safety requires questioning omissions of verification for infusions. Adherence to protocol is critical as insulin errors can lead to coma or death. A transferable strategy is to question and insist on RN double-checks for all high-alert infusion initiations.

Question 7

A 3-year-old child (weight 15 kg) is admitted with bacterial meningitis and has an order for intravenous morphine 0.05 mg/kg every 2 hours as needed for severe pain; current medications include ceftriaxone and acetaminophen. Morphine is high-alert in pediatrics due to respiratory depression risk. Which step is essential before administering this medication?

Calculate the dose and have a second licensed nurse independently verify the weight-based calculation and prepared dose before administration (correct answer)
Provide teaching to the parent about constipation prevention before giving the dose
Give the medication and then reassess respiratory rate and sedation level in 30 minutes
Document the pain score and planned dose in the record before drawing up the medication

Explanation: This question tests understanding of high-alert medication protocols and independent double-checks. The critical safety framework involves independent verification and high-alert medication protocols for pediatric opioids to mitigate respiratory risks. Calculating the weight-based dose and having a second licensed nurse independently verify the calculation and prepared dose ensures the highest safety standard by preventing dosing errors in children. Providing teaching first, giving without check, or documenting before drawing up neglects verification, increasing overdose potential. The decision-making principle in medication safety demands double-checking pediatric calculations. Adherence to protocol is essential as opioids can cause fatal depression if misdosed. A transferable strategy is to always verify weight-based high-alert doses with another RN before administering to pediatric patients.

Question 8

A 6-year-old child (weight 20 kg) is admitted for status asthmaticus and has an order for continuous intravenous magnesium sulfate infusion per provider order; current medications include albuterol nebulizers and intravenous methylprednisolone. Magnesium sulfate is high-alert in pediatrics due to dosing and cardiopulmonary depression risk. Which action should the nurse take FIRST to ensure medication safety?

Provide teaching to the parent about expected flushing and warmth before starting the infusion
Calculate the weight-based dose and have a second licensed nurse independently verify the calculation, medication concentration, and pump rate before administration (correct answer)
Begin the infusion and monitor deep tendon reflexes and respiratory rate every 15 minutes
Record the child's baseline vital signs in the chart and then prepare the infusion

Explanation: This question tests understanding of high-alert medication protocols and independent double-checks. The critical safety framework involves independent verification and high-alert medication protocols for pediatric magnesium sulfate to avoid dosing errors and cardiopulmonary issues. Calculating the weight-based dose and having a second licensed nurse independently verify the calculation, concentration, and pump rate ensures the highest safety standard by confirming accuracy in a vulnerable population. Providing teaching first, beginning infusion without check, or documenting vitals before preparation neglects the essential verification, risking overdose; monitoring afterward does not prevent errors. The decision-making principle in medication safety requires double-checking calculations for weight-based pediatric doses. Adherence to protocol is vital as magnesium can cause respiratory depression if incorrect. A transferable strategy is to always verify pediatric high-alert infusions with another RN, focusing on weight, dose, and rate.

Question 9

A 67-year-old client with heart failure is admitted for acute pulmonary edema and has an order for intravenous potassium chloride 40 mEq in 1,000 mL normal saline to infuse at 100 mL/hr; current medications include furosemide and carvedilol. Potassium chloride is high-alert due to risk of fatal dysrhythmias if administered incorrectly. Which step is ESSENTIAL before administering this medication?

Ask a nursing assistant to verify the infusion pump rate while the nurse hangs the bag
Document the potassium infusion in the medication record before starting it to ensure it is not missed
Have another licensed nurse independently verify the potassium concentration, route, and pump settings before starting the infusion (correct answer)
Start the infusion and then obtain a repeat serum potassium level in 4 hours

Question 10

A 55-year-old client with type 2 diabetes mellitus is receiving tube feedings and has an order for subcutaneous regular insulin 10 units every 6 hours; current medications include a proton pump inhibitor and antibiotics. Insulin is high-alert, and wrong timing or dose can cause severe hypoglycemia. Which step is ESSENTIAL before administering this medication?

Administer the insulin and then check blood glucose 1 hour later to evaluate response
Document the insulin administration before giving it so the next nurse knows it was completed
Have another licensed nurse independently verify the insulin dose and the correct vial or pen prior to administration (correct answer)
Teach the client signs of hypoglycemia before administering the insulin dose

Question 11

A 57-year-old client with type 2 diabetes mellitus is prescribed subcutaneous concentrated insulin regular U-500 per endocrinology order; current medications include metformin. Concentrated insulin is high-alert due to high risk of dosing errors leading to severe hypoglycemia. Which action should the nurse take FIRST to ensure medication safety?

Teach the client to recognize early signs of hypoglycemia, such as tremor, diaphoresis, and confusion, and to keep a fast-acting carbohydrate source available before administering the prescribed U-500 insulin.
Obtain an independent double-check with another licensed nurse verifying the concentration (U-500), ordered units, and the specific syringe or pen device to be used before administration. (correct answer)
Administer the prescribed U-500 insulin, then monitor blood glucose every 1 to 2 hours and treat hypoglycemia with IV dextrose per the standing protocol throughout the shift.
Document the prescribed dose, route, and injection site in the electronic medication administration record, scanning the U-500 vial to verify the label before drawing up the dose.

Explanation: For a high-alert medication such as concentrated insulin, the first safety action is an independent double-check by another licensed nurse before any dose is prepared. This verification must cover the exact concentration (U-500), the ordered number of units, and the specific syringe or pen device, because an error in any of these can cause severe hypoglycemia. Teaching the client to recognize hypoglycemia is valuable, but it does not prevent a wrong dose and is not the priority. Administering U-500 insulin and monitoring glucose afterward assumes the dose is correct; post-administration monitoring cannot undo a dangerous error. Documenting the dose and scanning the vial before drawing up the medication is a record-keeping and label-check step, not an independent verification by a second nurse. Therefore the nurse must first obtain the independent double-check.

Question 12

A 2-year-old toddler (weight 12 kg) is admitted for seizures and has an order for intravenous phenytoin 15 mg/kg loading dose; current medications include maintenance intravenous fluids. Phenytoin is high-alert due to cardiac dysrhythmias and hypotension if infused too rapidly or dosed incorrectly. Which action should the nurse take FIRST to ensure medication safety?

Administer the loading dose and then monitor blood pressure and heart rhythm during infusion
Calculate the weight-based dose and have a second licensed nurse independently verify the calculation, concentration, and infusion rate before administration (correct answer)
Document the seizure activity and planned dose before preparing the medication
Ask the parent to confirm the child's weight before preparing the dose

Explanation: This question tests understanding of high-alert medication protocols and independent double-checks. The critical safety framework involves independent verification and high-alert medication protocols for pediatric phenytoin to prevent cardiac issues. Calculating the weight-based dose and having a second nurse verify the calculation, concentration, and rate ensures the highest safety standard by ensuring accuracy. Administering without check, documenting first, or asking parent weight neglects verification, risking errors. The decision-making principle in medication safety requires pediatric dose double-checks. Adherence to protocol is essential for infusion-related risks. A transferable strategy is to verify all weight-based high-alert loads with another RN in children.

Question 13

A 64-year-old client with type 1 diabetes mellitus is prescribed subcutaneous insulin NPH 18 units in the morning; current medications include levothyroxine. Insulin is high-alert, and confusing insulin types can cause significant hypo- or hyperglycemia. The nurse should QUESTION which part of the medication administration process?

The nurse asks a second licensed nurse to independently verify the insulin type and dose before administration
The nurse prepares the insulin and administers it after checking the label and order without an independent double-check (correct answer)
The nurse confirms the client will be eating breakfast soon after administering intermediate-acting insulin
The nurse checks the client's current blood glucose prior to administration

Explanation: This question tests understanding of high-alert medication protocols and independent double-checks. The critical safety framework involves independent verification and high-alert medication protocols for insulin to prevent type confusion. The nurse should question preparing and administering without an independent double-check because it bypasses the highest safety standard, risking errors. Verifying with another RN, confirming meal timing, or checking glucose are appropriate but not to question. The decision-making principle in medication safety requires questioning skipped verifications. Adherence to protocol is vital for insulin safety. A transferable strategy is to question unverified high-alert preparations and enforce RN checks.

Question 14

A 65-year-old client is receiving chemotherapy for colon cancer and has an order for intravenous fluorouracil via infusion pump; current medications include ondansetron and dexamethasone. Chemotherapy is high-alert with serious harm if the wrong pump settings are used. Which step is ESSENTIAL before administering this medication?

Start the infusion and then monitor for nausea, vomiting, and mucositis
Document the chemotherapy administration in the record before programming the infusion pump
Have another licensed nurse independently verify the medication, dose, and infusion pump settings against the order before starting the infusion (correct answer)
Ask a nursing assistant to confirm the client's identification band before initiating the chemotherapy

Explanation: This question tests understanding of high-alert medication protocols and independent double-checks. The critical safety framework involves independent verification and adherence to high-alert medication protocols to prevent errors in administration. Having another licensed nurse independently verify the medication, dose, and infusion pump settings against the order before starting the infusion ensures the highest safety standard by providing a second layer of confirmation to catch potential errors that could lead to serious harm with chemotherapy like fluorouracil. Starting the infusion and then monitoring for side effects (A) is incorrect because it neglects pre-administration verification and focuses on post-infusion monitoring; documenting before programming the pump (B) is less safe as it prioritizes paperwork over verification and could lead to errors if done prematurely; asking a nursing assistant to confirm identification (D) is inadequate because nursing assistants are not qualified for medication verification and this step only addresses identification, not the full protocol. The decision-making principle in medication safety emphasizes error prevention through systematic checks rather than relying on a single individual. Strict adherence to protocol is crucial to minimize risks associated with high-alert medications that can cause irreversible harm if administered incorrectly. A transferable strategy for ensuring safety when administering high-alert medications is to always implement independent double-checks by qualified personnel before initiation, regardless of familiarity with the procedure.

Question 15

A 73-year-old client with chronic kidney disease (estimated glomerular filtration rate 24 mL/min/1.73 m²) is admitted for pain crisis due to vertebral fracture and has an order for intravenous morphine 4 mg every 2 hours as needed; current medications include gabapentin. Opioids are high-alert and may accumulate in renal impairment, increasing risk of oversedation and respiratory depression. What is the nurse's PRIORITY action before medication administration?

Administer the morphine and then monitor respiratory rate and sedation level
Clarify dosing appropriateness with the provider due to renal impairment and obtain an independent double-check of the final dose with another licensed nurse before giving (correct answer)
Document the client's pain score and intended dose before drawing up the medication
Teach the client to use nonpharmacologic pain techniques before administering the opioid

Explanation: This question tests understanding of high-alert medication protocols and independent double-checks. The critical safety framework involves independent verification and high-alert medication protocols for opioids in renal impairment. Clarifying dosing with the provider and obtaining a double-check ensures the highest safety standard by preventing accumulation and depression. Administering without clarification, documenting first, or teaching techniques neglects necessary steps. The decision-making principle in medication safety prioritizes order clarification in at-risk patients. Adherence to protocol is essential to avoid oversedation. A transferable strategy is to clarify and verify high-alert doses in renal patients with another RN.

Question 16

A 74-year-old client with chronic kidney disease (estimated glomerular filtration rate 28 mL/min/1.73 m²) is admitted for deep vein thrombosis and has a new order for enoxaparin 80 mg subcutaneously every 12 hours; current medications include aspirin and atorvastatin. Enoxaparin is high-alert and may require dose adjustment in renal impairment to prevent bleeding. What is the nurse's PRIORITY action before medication administration?

Administer the dose as ordered and monitor for bruising and hematuria afterward
Contact the provider to clarify renal dose adjustment needs and obtain an independent double-check of the final dose with another licensed nurse before giving (correct answer)
Document the injection site and time in the electronic record before preparing the medication
Ask the client to confirm the dose they usually take at home before administering

Explanation: This question tests understanding of high-alert medication protocols and independent double-checks. The critical safety framework involves independent verification and high-alert medication protocols for enoxaparin, especially in renal impairment. Contacting the provider to clarify renal dose adjustment and obtaining an independent double-check ensures the highest safety standard by addressing potential overdose risks and verifying the dose. Administering without clarification, documenting before preparation, or asking the client to confirm neglects verification and adjustment needs, increasing bleeding risk. The decision-making principle in medication safety requires clarifying inappropriate orders before proceeding. Adherence to protocol is vital as enoxaparin accumulation in renal failure can cause hemorrhage. A transferable strategy is to always verify high-alert anticoagulant doses with providers and another RN when patient factors like renal function are involved.

Question 17

An 81-year-old client with renal impairment (estimated glomerular filtration rate 18 mL/min/1.73 m²) is admitted for pulmonary embolism and has an order for warfarin 5 mg by mouth daily starting tonight; current medications include amiodarone and aspirin. Warfarin is high-alert due to major bleeding risk, especially with drug interactions and renal impairment. Which step is ESSENTIAL before administering this medication?

Administer the warfarin and then monitor for bleeding and check the international normalized ratio in the morning
Document the dose in the medication record before giving it to ensure timely administration
Have another licensed nurse independently verify the ordered dose and confirm the most recent international normalized ratio and interaction risks prior to administration (correct answer)
Ask a nursing assistant to confirm whether the client has had any bruising today before administration

Question 18

A 70-year-old client with chronic kidney disease (estimated glomerular filtration rate 25 mL/min/1.73 m²) is admitted for cellulitis and has an order for intravenous gentamicin; current medications include amlodipine and warfarin. Aminoglycosides are high-alert due to nephrotoxicity and ototoxicity if dosed incorrectly. Which action should the nurse take FIRST to ensure medication safety?

Administer the ordered gentamicin dose promptly, then schedule a trough level to be drawn just before the next scheduled dose.
Document the medication start time and infusion rate on the medication administration record before verifying the ordered dose with renal function considerations.
Verify the ordered dose with renal function considerations per policy and obtain an independent double-check by another licensed nurse before administration. (correct answer)
Ask a nursing assistant to confirm the client's allergy status and then document the verification in the electronic medication record before starting the infusion.

Explanation: The first priority for a high-alert aminoglycoside in a client with advanced chronic kidney disease is to verify the ordered dose against renal function and have a second licensed nurse independently double-check it before any medication is given. Gentamicin clearance depends on the estimated glomerular filtration rate, and an incorrect dose can cause nephrotoxicity or ototoxicity; documentation and infusion-related tasks come after dose verification. Administering the dose promptly and scheduling a trough later skips the verification step and exposes the client to an unverified first dose. Documenting the start time and infusion rate before verifying the dose inverts the correct sequence and omits the independent double-check. Asking a nursing assistant to confirm allergy status and then documenting that verification delegates a nursing assessment to unlicensed personnel and does not address renal dose verification or the required independent double-check. Only the choice that verifies the dose with renal function per policy and obtains an independent double-check by another licensed nurse meets the standard of care for this high-alert medication.

Question 19

A 77-year-old client with renal impairment (estimated glomerular filtration rate 30 mL/min/1.73 m²) is admitted for pneumonia and has an order for intravenous vancomycin 1,500 mg every 12 hours; current medications include losartan and insulin glargine. Vancomycin is high-alert due to nephrotoxicity and infusion-related reactions if dosed or administered incorrectly. What is the nurse's PRIORITY action before medication administration?

Start the vancomycin infusion at the prescribed rate and monitor the client for flushing, hypotension, and other nephrotoxic effects throughout the entire administration.
Document the planned infusion start time in the electronic health record before verifying the ordered vancomycin dose and rate with another licensed nurse.
Have another licensed nurse independently verify the ordered dose and infusion rate and confirm appropriateness with renal function per policy before administration. (correct answer)
Ask the client to state their name and date of birth and then administer the medication using the rights of medication administration.

Explanation: The nurse's priority before administering any high-alert medication is to perform an independent double-check. For vancomycin in a client with renal impairment, the correct action is to have another licensed nurse independently verify the ordered dose and infusion rate and confirm that the dose is appropriate for the client's renal function per policy. This verification prevents an unsafe dose that could worsen nephrotoxicity. Starting the infusion while monitoring for flushing, hypotension, and nephrotoxic effects addresses infusion-related reactions but does not catch a dosing error before the drug is given. Documenting the planned start time before verifying the dose and rate puts documentation ahead of the critical safety check. Asking the client for identification and then administering uses one safety check but omits the essential double-check of the dose and renal appropriateness. Therefore, only the independent verification by a second nurse meets the priority action.

Question 20

A 45-year-old client with acute lymphoblastic leukemia is scheduled to receive intravenous chemotherapy today: vincristine 2 mg in 50 mL normal saline over 10 minutes. Current medications include ondansetron and allopurinol; the client has a central venous catheter. A medication error could cause severe tissue injury or life-threatening toxicity. Which action should the nurse take FIRST to ensure medication safety before administration?

Provide teaching about expected side effects and when to call the nurse before initiating the infusion
Ask a second chemotherapy-competent licensed nurse to independently verify the client, medication, dose, route, and infusion parameters against the order (correct answer)
Begin the infusion and monitor closely for extravasation at the central line insertion site
Document the chemotherapy consent and premedications as given before verifying the chemotherapy drug and dose

Explanation: This question tests understanding of high-alert medication protocols and independent double-checks for chemotherapy administration. The critical safety framework requires chemotherapy-competent nurses to perform independent verification of all chemotherapy parameters before administration. Option B ensures the highest safety standard by having a second chemotherapy-competent licensed nurse independently verify the client identity, medication, dose, route, and infusion parameters against the original order. Option A provides teaching without verification, option C begins infusion without double-check risking severe toxicity, and option D documents before verifying which violates safety protocols. The decision-making principle is that chemotherapy requires specialized competency and mandatory independent double-checks by qualified nurses to prevent potentially fatal errors. A transferable strategy is to always ensure both nurses involved in chemotherapy verification are chemotherapy-competent and to verify all five rights plus infusion parameters before any chemotherapy administration.
