Question 1 of 5
A nurse is caring for a client who has a new prescription of phenelzine (Nardil) for the treatment of depression. Which of the following indicates that the client has developed an adverse effect of this medication?
Correct Answer: B
Rationale: The correct answer is B: Orthostatic hypotension. Phenelzine is a monoamine oxidase inhibitor (MAOI) used to treat depression. Orthostatic hypotension is a common adverse effect of MAOIs due to their effects on blood pressure regulation. When a client experiences orthostatic hypotension, their blood pressure drops significantly upon standing, leading to dizziness or fainting. This can be dangerous and requires monitoring.
Hearing loss (choice
A) is not a common adverse effect of phenelzine. Weight loss (choice
C) can occur but is less common than orthostatic hypotension. Gastrointestinal bleeding (choice
D) is not a typical adverse effect of phenelzine. The key is to focus on the known side effects of phenelzine and select the one that aligns best with the presented symptom.
Question 2 of 5
Lipoproteins transport lipids through the blood for utilization by tissues, storage in adipose tissue, or excretion by the
Correct Answer: A
Rationale: The correct answer is A: liver. The liver plays a crucial role in lipid metabolism by producing lipoproteins that transport lipids in the blood. The liver also processes and stores lipids for later use or excretes them. The other choices are incorrect because the respiratory system, proteins, and kidney do not primarily function in the transportation of lipids through the blood.
Question 3 of 5
A client taking nitroglycerin (Nitrostat) complains of a headache. Which conclusion is most appropriate by the nurse?
Correct Answer: A
Rationale: The correct answer is A. Nitroglycerin commonly causes headaches due to its vasodilatory effects, which can lead to decreased blood pressure and resulting headaches. This is a known side effect. Option B is incorrect as headaches are a common side effect of nitroglycerin. Option C is incorrect as taking nitroglycerin with a high-fat meal does not prevent headaches. Option D is incorrect as a headache is not indicative of a serious allergic reaction.
Therefore, the most appropriate conclusion is that the headache experienced by the client is likely due to nitroglycerin's common side effect.
Question 4 of 5
An older patient has a prescription for sertraline (Zoloft) 25 mg/day, P O. to be taken for 1 week and then increased to 50 mg/day the second week. The pharmacy gives the patient 50-mg tablets. How many tablets will the patient take per day during the first week?
Correct Answer: D
Rationale: The correct answer is D: Half tablet. During the first week, the patient is prescribed 25 mg/day of sertraline. Since the pharmacy provides 50-mg tablets, the patient needs to take half of the tablet to achieve the prescribed dosage. This would be equivalent to 25 mg, as required. Taking one and one-half tablets (
A) would exceed the prescribed dosage, one-quarter of the tablet (
B) would not provide enough medication, and taking one tablet (
C) would also exceed the prescribed dosage.
Therefore, the correct answer is half tablet (
D) to achieve the prescribed 25 mg/day dosage during the first week.
Question 5 of 5
A nurse is collecting data from a client who has been taking sertraline (Zoloft) for the past 2 weeks. Which of the following data collection findings should alert the nurse to the possibility that the client is developing serotonin syndrome?
Correct Answer: A
Rationale: The correct answer is A: Fever. Serotonin syndrome is a potentially life-threatening condition caused by excessive serotonin levels in the body. Fever is a hallmark symptom of serotonin syndrome, along with other symptoms such as confusion, agitation, rapid heart rate, dilated pupils, and high blood pressure. In this scenario, the nurse should be alert to fever as it could indicate the development of serotonin syndrome. Tinnitus (choice
B), bruising (choice
C), and rash (choice
D) are not typical symptoms of serotonin syndrome and would not necessarily indicate its development.
