1. What is the therapeutic use of Phenytoin?

Correct answer: C

Rationale: Phenytoin is primarily used to diminish seizure activity and is effective in terminating ventricular arrhythmias. It works by stabilizing neuronal membranes, reducing repetitive neuronal firing, and limiting the spread of seizure activity in the brain. While phenytoin does not have a direct role in preventing thrombus formation or extending existing thrombi, it is crucial in managing seizures and certain arrhythmias.

2. When educating a client with a new prescription for Omeprazole to manage GERD, which of the following information should the nurse include?

Correct answer: A

Rationale: The correct answer is to take the medication before meals. Omeprazole should be taken before meals to ensure its effectiveness in reducing stomach acid production. This timing allows the medication to work on reducing acid secretion when the stomach is most actively producing it, leading to better control of symptoms. Choice B is incorrect because not all patients with GERD need to take Omeprazole for the rest of their lives; the duration of treatment varies. Choice C is incorrect as there is no specific recommendation to increase vitamin C intake while taking Omeprazole. Choice D is incorrect because Omeprazole may take a few days to start providing symptom relief, so immediate relief should not be expected.

3. A client has a new prescription for Hydralazine. Which of the following adverse effects should the nurse instruct the client to monitor?

Correct answer: A

Rationale: Corrected Rationale: Hydralazine is a vasodilator that can cause reflex tachycardia as an adverse effect. The client should monitor their pulse and report any significant increases, as tachycardia can indicate a severe adverse reaction to the medication. Choice B, Hyperglycemia, is not a common adverse effect of Hydralazine. Choice C, Hyponatremia, and Choice D, Constipation, are also not typically associated with Hydralazine use. Therefore, the correct answer is A: Tachycardia.

4. A client has a new prescription for Zolpidem. Which of the following instructions should the nurse include?

Correct answer: A

Rationale: Zolpidem is classified as Pregnancy Risk Category C. It is important for the client to inform the provider if they plan to become pregnant because the medication may need to be adjusted or changed to ensure the safety of the fetus. This communication allows for appropriate monitoring and adjustments to be made to the treatment plan. Choice B is incorrect because zolpidem should be taken just before going to bed, not specifically 1 hour before. Choice C is incorrect as zolpidem is a short-acting medication, and it does not require a full 6 hours for sleep. Choice D is incorrect because zolpidem can be taken with or without food, so taking it with a bedtime snack is not contraindicated.

5. A client is prescribed Propylthiouracil (PTU) for the treatment of Graves' disease. Which adverse effect should the client be instructed to report?

Correct answer: A

Rationale: The correct answer is A: Sore throat. A sore throat and fever can indicate agranulocytosis, a serious adverse effect of PTU that can lead to a decreased white blood cell count. This condition requires immediate medical attention to prevent complications. Choice B, drowsiness, is not typically associated with PTU and is not a common adverse effect that needs to be reported. Choice C, urinary retention, is not a typical adverse effect of PTU; therefore, it is not the correct answer. Choice D, heat intolerance, is a symptom commonly seen in hyperthyroidism, which PTU is used to treat, so it is not an adverse effect that needs to be specifically reported.
