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 with a history of deep vein thrombosis is prescribed warfarin. The nurse should monitor for which potential adverse effect?
- A. Increased risk of bleeding
- B. Decreased risk of bleeding
- C. Increased risk of infection
- D. Decreased risk of infection
Correct answer: A
Rationale: The correct answer is A: Increased risk of bleeding. Warfarin is an anticoagulant medication that works by prolonging the time it takes for blood to clot. Therefore, a potential adverse effect of warfarin is an increased risk of bleeding. It is crucial for the nurse to monitor the client for signs of bleeding, such as easy bruising, prolonged bleeding from cuts, nosebleeds, or blood in the urine or stool. Monitoring for these signs is essential to prevent serious complications associated with excessive bleeding. Choices B, C, and D are incorrect because warfarin does not decrease the risk of bleeding, increase the risk of infection, or decrease the risk of infection. The primary concern with warfarin therapy is the potential for bleeding complications, so close monitoring for signs of bleeding is essential.
3. A client with a diagnosis of depression is prescribed escitalopram. Which statement by the client indicates the need for further teaching?
- A. I should take this medication in the morning with food.
- B. This medication may take 1 to 4 weeks to notice improvement in symptoms.
- C. I can stop taking this medication once I feel better.
- D. This medication might make me feel drowsy.
Correct answer: C
Rationale: It is crucial for clients to understand that they should not discontinue escitalopram abruptly, even if they start feeling better. Stopping the medication suddenly can lead to withdrawal symptoms or a relapse of depression. It is essential to complete the full course of treatment as prescribed by the healthcare provider to ensure the best outcomes and prevent potential complications.
4. A client with major depressive disorder is prescribed bupropion. Which statement by the client indicates the need for further teaching?
- A. This medication may cause weight gain.
- B. This medication may take several weeks to take effect.
- C. I should avoid alcohol while taking this medication.
- D. I should take this medication in the morning with food.
Correct answer: A
Rationale: The correct answer is A because bupropion is associated with weight loss rather than weight gain. It is important for the client to be aware of this potential side effect. Choice B is correct because bupropion may take several weeks to exhibit its full therapeutic effects. Choice C is also accurate as alcohol consumption should be avoided while taking bupropion due to the risk of seizures. Choice D is correct as taking bupropion in the morning with food can help reduce the risk of gastrointestinal side effects.
5. A 43-year-old female client who has had a thyroidectomy due to Grave's disease is prescribed a thyroid replacement hormone. Which signs and symptoms are associated with thyroid hormone toxicity and should be reported promptly to the healthcare provider?
- A. Tinnitus and dizziness
- B. Tachycardia and chest pain
- C. Dry skin and intolerance to cold
- D. Weight gain and increased appetite
Correct answer: B
Rationale: The correct answer is B: Tachycardia and chest pain. Signs and symptoms of thyroid hormone toxicity, especially in cases of excessive dosage, include tachycardia (rapid heart rate) and chest pain. These symptoms are consistent with hyperthyroidism, where the body is receiving an excessive amount of thyroid hormone. It is crucial to report these symptoms promptly to the healthcare provider to adjust the medication dosage and prevent potential complications. Choices A, C, and D are not indicative of thyroid hormone toxicity. Tinnitus and dizziness (Choice A) are not typical symptoms of thyroid hormone toxicity. Dry skin and intolerance to cold (Choice C) are more common in hypothyroidism, while weight gain and increased appetite (Choice D) are associated with hypothyroidism as well, not thyroid hormone toxicity.
