Example Question #111 : Pharmacology
Lamotrigine carries a black-box warning about what side effect?
Aseptic meningitis
Stevens–Johnson syndrome
DRESS syndrome (drug reaction/rash with eosinophilia and systemic symptoms)
All of these
All of these
Lamotrigine carries a black box warning about the following side effects:
- Stevens–Johnson syndrome
- Toxic epidermal necrolysis
- DRESS syndrome (drug reaction/rash with eosinophilia and systemic symptoms)
- Aseptic meningitis
Example Question #111 : Nclex
Phenelzine is what class of drug?
Monoamine oxidase inhibitor (MAOI)
Narcotic
Tricyclic antidepressant
Alpha adrenergic agonist
Monoamine oxidase inhibitor (MAOI)
Phenelzine is a monoamine oxidase inhibitor (MAOI). Drugs in this class work by inhibition of monoamine oxidase enzymes, the enzymes responsible for the break down of serotonin, dopamine, and adrenaline.
Example Question #112 : Pharmacology
What class of drugs is diazepam?
Methaqualone analogue
Benzodiazepine
Nonbenzodiazepine sedative
Barbituate
Benzodiazepine
Diazepam is a benzodiazepine. This class of drugs works by potentiating the effects of GABA, our primary inhibitory neurotransmitter, at the GABAa receptor.
Example Question #114 : Pharmacology
Bromocriptine belongs to what class of drug?
Peripheral dopamine decarboxylase inhibitor
Anxiolytic
Anticholinergic
Dopamine agonist
Dopamine agonist
Bromocriptine is a dopamine agonist used in the treatment for Parkinson's disease, pituitary tumors, and type 2 diabetes.
Example Question #111 : Nclex
A patient taking haloperidol complains of abnormal, unintentional movements of his tongue and face. The nurse knows that the patient is experiencing which of the following side effects of haloperidol?
Convulsions and seizures
Tardive dyskinesia
Dizziness and weakness
Neuroleptic malignant syndrome
Increased anxiety
Tardive dyskinesia
All of the listed options are side effects of haloperidol, but tardive dyskinesia (TD) is the only one that manifests with involuntary, dyskinetic movements in their face, lips, tongue, trunk, and extremities. TD more frequently occurs among elderly female patients taking long-term dopamine-antagonist medications. Dizziness, weakness, convulsions, seizures, and anxiety are also side effects of haloperidol. Neuroleptic Malignant Syndrome presents with fever and high/unstable blood pressure, muscle cramps and tremors, altered mental status (such as delirium, agitation, or a coma).
Example Question #114 : Pharmacology
You are the nurse taking care of a patient who is experiencing a panic attack. You are instructed to give the patient a dose of lorazepam. Which of the drug classes below describes lorazepam?
Benzodiazepine
Beta-blocker
Amphetamine
Alpha-blocker
Barbiturate
Benzodiazepine
The correct answer is "benzodiazepine," as lorazepam, also known as Ativan, is a benzodiazepine drug. Benzodiazepines act by increasing the efficacy of the neurotransmitter, GABA, when it acts upon its particular receptors. They have potent anti-anxiety properties, among other properties, and are frequently given during the initial phase of a panic attack to calm the patient.
On the other hand, the other choices are incorrect. Phenobarbital is an example of a barbiturate. Proproanolol is an example of a beta-blocker. Tamsulosin is an example of an alpha-blocker. Methamphetamine is an example of an amphetamine.

Example Question #31 : Drug Identification
5-fluouracil is used to treat which of the following conditions?
Ulcerative colitis
Colorectal, breast, and ovarian cancer
Myasthenia gravis
Rheumatoid arthritis
Colorectal, breast, and ovarian cancer
5-fluouracil is a fluoropyrimidine analog which inhibits translation, synthesis, and function of RNA and DNA, thus slowing down cellular metabolism. It is used in treatment of colorectal, breast, and ovarian cancer, in addition to cancers of the GI and head and neck.
Example Question #34 : Drug Identification
Which of the following laboratory values would indicate toxicity in the client taking acetaminophen daily?
Prothrombin time of 12 seconds
Sodium level of 140 mEq/L
Direct bilirubin level of 2mg/dL
Platelet count of 400,000/mm3
Direct bilirubin level of 2mg/dL
A direct bilirubin level of 2mg/dL or greater indicates acetaminophen toxicity.
Example Question #116 : Pharmacology
The purpose of misoprostol in a client who chronically uses nonsteroidal anti-inflammatory drugs (NSAIDs) is:
Relief of epigastric pain
Decrease in serum phosphorus level
Increased white blood cell count
Reduction of steatorrhea
Relief of epigastric pain
Misoprostol is used for the prevention of non steroidal anti inflammatory drug (NSAID) induced gastric ulcers. Taking this drug will prevent gastric ulcers and relieve epigastric pain.
