Question 1 of 5
Which drug is the antidote of Alprazolam?
Correct Answer: C
Rationale: Flumazenil is the specific antidote for Alprazolam, which is a benzodiazepine sedative-hypnotic drug. Flumazenil works by competitively inhibiting the actions of benzodiazepines at the benzodiazepine receptor site on the gamma-aminobutyric acid (GAB
A) receptor complex. It effectively reverses the sedative effects of benzodiazepines like Alprazolam, making it the appropriate antidote in cases of benzodiazepine overdose or toxicity. The other options provided (Physostigmine, Protamine sulfate, and Acetylcysteine) are unrelated to Alprazolam and are not indicated as antidotes for this specific drug.
Question 2 of 5
A child was brought to the emergency room complaining of right upper quadrant abdominal pain, nausea, and vomiting. Upon the interview of the nurse to the mother, the client has been taking a long-
Correct Answer: D
Rationale: The symptoms described in the scenario, along with the patient's history of taking valproic acid, suggest a potential case of valproic acid toxicity. Acetylcysteine is the antidote for valproic acid overdose and should be readily available for treatment in case of toxicity. Acetylcysteine works by replenishing depleted glutathione levels caused by valproic acid toxicity. It helps to prevent further liver damage and can improve outcomes in cases of overdose. Administering acetylcysteine in a timely manner can be crucial in managing valproic acid toxicity.
Question 3 of 5
Which of the following drugs blocks reuptake of 5-hydroxytryptamine (serotonin)?
Correct Answer: D
Rationale: Serotonin reuptake blockade increases synaptic levels. Buspirone, a 5-HT1A agonist, treats anxiety without reuptake effects. Pizotifen, a serotonin antagonist, prevents migraines. Granisetron, a 5-HT3 antagonist, controls nausea. Paroxetine, an SSRI, potently inhibits serotonin reuptake, elevating mood in depression. Sumatriptan activates 5-HT1 receptors. Paroxetine's mechanism is central to its antidepressant efficacy, distinguishing it from receptor modulators.
Question 4 of 5
A patient is taking aspirin for secondary prevention of myocardial infarction and is experiencing moderate gastrointestinal upset. The nurse will contact the patient's provider to discuss changing from aspirin to which of the following?
Correct Answer: C
Rationale: The patient is experiencing gastrointestinal upset from taking aspirin. Enteric-coated aspirin would be a suitable alternative in this case because the special coating on the aspirin helps protect the stomach lining and reduces the risk of gastrointestinal irritation. Switching to an enteric-coated aspirin can still provide the antiplatelet benefits needed for secondary prevention of myocardial infarction while minimizing the gastrointestinal side effects. It is important to address the patient's symptoms while ensuring that they continue to receive appropriate treatment for their medical condition.
Question 5 of 5
What medication, if ordered for an 8-year-old patient, should the nurse question? (Select all that apply.)
Correct Answer: A
Rationale: Amiodarone, labetalol, and carvedilol are not indicated for pediatric use and do not have established pediatric dosages. Phentolamine and prazosin have established pediatric dosages and would not need to be questioned. The nurse should always verify the appropriateness of medications for pediatric patients, as their pharmacokinetics and pharmacodynamics differ from adults.
