The nurse cares for a patient hospitalized for 5 days with pneumonia. He is about to be discharged and the nurse is providing discharge instructions to the patient and the family. Which statement made by the patient’s family should most concern the nurse?
When a patient has an infection and is prescribed antibiotics, the patient should always take the full course of the medication and never discontinue the medication. It is easy for patients to believe they can stop taking the medication when the symptoms are resolved, but the nurse needs to educate the patient to continue the full regimen. The rest of the statements are accurate; the patient must get adequate rest, eat well, use the incentive spirometer, and stay away from others who are sick until he is well.

A 39-year-old man presents to the ER with weakness, confusion, and vertigo. His heart rate is 91 and bounding, blood pressure is , temperature is
, and blood glucose is
. He is non-diabetic, he is not on any medication, and he denies recreational drug use. Which of the following is the most likely cause of his symptoms?
The most likely cause of his symptoms is hypoglycemia, which is defined as a blood glucose below in a non-diabetic patient. The symptoms of hypoglycemia include altered consciousness, tremors, weakness, vertigo, headaches, heart palpitations, and a bounding pulse.
A temperature of is not considered abnormal as it may reflect a normal variation in body temperature.
His blood pressure is slightly elevated, but it is unclear whether this is typical for him or whether this represents a significant change from his normal blood pressure. Regardless it would not likely be sufficiently elevated to cause his symptoms.
It is also possible he may be experiencing a panic attack, but in the presence of his depressed blood sugar (and absence of signs of anxiety), hypoglycemia is the most likely cause of his symptoms.

Abdominal rigidity and decreased bowel sounds would raise your suspicions of what condition?
Abdominal rigidity and decreased bowel sounds are classic signs of peritontis. In addition, the patient will often want to lie very still, as any motion often increases pain. Cystitis, ulcerative colitis, and cholecystitis all may cause significant abdominal tenderness but would not generally result in rigidity or decreased bowel sounds.

Why are blind finger-sweeps not recommended in infants with foreign objects in their oral cavities or airways?
Blind finger sweeps are not recommended in an infant with airway restriction due to a foreign object because they may inadvertently force the object deeper into the airway. A finger sweep should only be used if the object can be visualized. Injury to the oral cavity would not be a primary concern in the case of airway restriction, and a finger sweep would not be expected to trigger either gasping or vomiting in an infant.

Standard precautions are a set of guidelines that are designed to prevent the spread of infection by exposure to an individual or their bodily fluids. Which of the following is not considered a standard precaution?
Standard precautions should be utilized in the care of every patient. Hand hygiene before and after patient contact is always required. Clean, functioning, equipment should always be available. The use of personal protective gear when there is potential to blood or bodily fluid exposure is critical. This includes the proper disposal of soiled materials such as linens. However, it is not necessary for patients to be housed in private rooms unless they are affected by an infectious disease. If private rooms for infectious individuals are unavailable, it is acceptable to place patients in cohorts of the same infectious disease.

What should you expect to hear when percussing the seventh intercostal space along the right midclavicular line?
When percussing the seventh intercostal space along the right midclavicular line, you should expect to hear a dull note, as this is directly over the solid mass of the liver.
The border of the liver can be found by percussing in a descending line along the intercostal spaces of the right midclavicular line, starting at the clavicle. The superior border of the liver can be measured at the point where percussion transforms from resonant or hyperresonant (indicating the air-filled lung) to dull (indicating the solid mass of the liver).

On palpating the abdominal aorta, the diameter of the aorta is measured at 3cm. This indicates an abdominal aorta that is __________.
A healthy and normal abdominal aorta will measure between 2.5-3cm in diameter. An abdominal aorta over 3cm and under 5cm in diameter is considered to be enlarged, and surgery to prevent abdominal aortic aneurism is generally performed on abdominal aortas that surpass 5cm in diameter in females or 5.5cm in diameter in males.

A patient reports to urgent care for colicky pain in the upper right quadrant that they rate as a seven out of ten. The night before they ate a fatty meal with two glasses of wine. Which of the following tests would help you asses for cholecystitis?
A positive Murphy's sign is an indication of cholecystitis, or gallbladder inflammation. Testing for Murphy's sign is performed during an abdominal exam by asking the patient to breathe out slowly while the fingers of the examiner are slid under the right costal margin and held in place with firm pressure. The patient is then asked to inhale, which forces the abdominal contents upward. Murphy's sign is considered positive if the patient winces or flinches when breathing in, due to pain when the inflamed gallbladder comes in contact with the examiner's fingertips.
Rovsing's sign, psoas sign, and McBurney's point are all tests for appendicitis.

When testing for the strength of the left biceps brachii muscle, a patient is found to be able to move freely against gravity, but is unable to flex against very gentle resistance by the examiner. What grade of muscle strength should their bicep be assigned?
In this case, the patient is able to move their biceps brachii against gravity, but they are unable to move against gentle resistance by the examiner. This means the muscle strength should be graded at .
The muscle strength grade is as follows:
: no contraction
: muscle contraction, but no movement
: movement with gravity, but not against gravity
: movement against gravity, but not against resistance
: movement against mild resistance by the examiner
: normal muscle strength
