HESI Practice Test Pharmacology
1. A client who received a prescription for cyclosporine ophthalmic emulsion for dry eyes asks the practical nurse (PN) if it is safe to continue using artificial tears. What information should the PN provide?
- A. Avoid using artificial tears because they decrease the efficacy of cyclosporine.
- B. Discontinue the use of both products if transient blurring occurs after administration.
- C. Allow a 15-minute interval between the administration of cyclosporine and artificial tears.
- D. Discontinue the use of cyclosporine and artificial tears when tear production reaches a normal level.
Correct answer: C
Rationale: The correct answer is to allow a 15-minute interval between the administration of cyclosporine and artificial tears. Cyclosporine, an ophthalmic emulsion that increases tear production, can be used in conjunction with artificial tears as long as the products are administered 15 minutes apart. This interval helps to prevent any potential interactions between the two products and ensures optimal effectiveness of cyclosporine for treating dry eyes.
2. A client is prescribed clonidine 0.1 mg/24 hours via a transdermal patch. Which client outcome would indicate that the medication is effective?
- A. No complaints of recent episodes of angina
- B. Change in peripheral edema from +3 to +1
- C. No complaints of new onset of nausea or vomiting
- D. Blood pressure changes from 180/120 to 140/70 mm Hg
Correct answer: D
Rationale: Clonidine is an antihypertensive agent that works centrally to reduce blood pressure. A significant decrease in blood pressure, such as changing from 180/120 to 140/70 mm Hg, indicates that the medication is effectively managing hypertension. Monitoring blood pressure levels is crucial in assessing the response to clonidine therapy. Choices A, B, and C are incorrect as they do not directly relate to the therapeutic effect of clonidine in managing hypertension, which is the primary goal of the medication in this scenario.
3. How does omeprazole work in treating a peptic ulcer?
- A. Increasing the production of gastric acid
- B. Neutralizing stomach acid
- C. Coating the stomach lining
- D. Reducing gastric acid secretion
Correct answer: D
Rationale: Omeprazole is a proton pump inhibitor that works by reducing gastric acid secretion. By inhibiting the enzyme responsible for pumping acid into the stomach, omeprazole helps decrease the acidity level in the stomach, providing relief from peptic ulcers. Option A is incorrect because omeprazole does not increase gastric acid production; instead, it decreases it. Option B is incorrect as omeprazole does not neutralize existing stomach acid but rather reduces its secretion. Option C is incorrect as omeprazole does not coat the stomach lining but acts on reducing acid secretion.
4. A client with a diagnosis of schizophrenia is prescribed lurasidone. The nurse should monitor the client for which potential side effect?
- A. Weight gain
- B. Dry mouth
- C. Nausea
- D. Headache
Correct answer: A
Rationale: The correct answer is A: Weight gain. When a client is prescribed lurasidone, monitoring for weight gain is essential as lurasidone can cause this side effect. Patients on lurasidone should have their weight monitored regularly to detect any changes that may occur. Options B, C, and D are not typically associated with lurasidone use, making them less likely to be a direct side effect of this medication.
5. A client with diabetes mellitus type 1 is prescribed insulin glargine. When should the nurse instruct the client to administer this medication?
- A. Before meals
- B. After meals
- C. At bedtime
- D. In the morning
Correct answer: C
Rationale: Corrected Rationale: Insulin glargine is a long-acting insulin that provides a consistent level of insulin over 24 hours. Administering it at bedtime helps mimic the body's natural insulin secretion pattern and provides optimal blood glucose control during the night and throughout the day. Choice A (Before meals) is incorrect because insulin glargine is not a rapid-acting insulin meant to cover meals. Choice B (After meals) is incorrect as the timing doesn't align with the insulin's mechanism. Choice D (In the morning) is incorrect as administering insulin glargine in the morning may not provide adequate coverage throughout the night and the following day.
