Pharmacology HESI 55 Questions 2023
1. A client has been diagnosed with open-angle glaucoma. The healthcare provider prescribes pilocarpine 1% eye drops. The nurse explains that which action of this drug makes it a useful treatment for the client's condition?
- A. The ciliary muscle contracts, increasing the outflow of aqueous humor in the eye.
- B. Ciliary muscles are paralyzed to decrease accommodation.
- C. Bilateral mydriasis with cycloplegia is accomplished.
- D. The production of aqueous humor in the eyes is decreased.
Correct answer: A
Rationale: Pilocarpine, a cholinergic agent, stimulates the ciliary muscle to contract, which opens the trabecular meshwork and facilitates the outflow of aqueous humor, reducing intraocular pressure. This mechanism helps in managing open-angle glaucoma by improving drainage and lowering pressure within the eye. Choice A is correct because the contraction of the ciliary muscle increases the outflow of aqueous humor, aiding in the treatment of open-angle glaucoma. Choices B, C, and D are incorrect because they do not describe the mechanism of action of pilocarpine in treating glaucoma.
2. A client with a history of chronic kidney disease is prescribed epoetin alfa. The nurse should monitor for which potential adverse effect?
- A. Hypertension
- B. Hypotension
- C. Hyperglycemia
- D. Tachycardia
Correct answer: A
Rationale: The correct answer is A: Hypertension. Epoetin alfa can lead to hypertension as an adverse effect because it stimulates increased red blood cell production. This can result in elevated blood pressure levels, requiring careful monitoring by the nurse to prevent complications. Choice B, hypotension, is incorrect because epoetin alfa is more likely to cause hypertension rather than hypotension. Choice C, hyperglycemia, and Choice D, tachycardia, are also incorrect as they are not commonly associated with the use of epoetin alfa.
3. When a client with hypertension is prescribed losartan, what potential side effect should the nurse monitor for?
- A. Hyperkalemia
- B. Dry cough
- C. Bradycardia
- D. Headache
Correct answer: B
Rationale: The correct answer is B: Dry cough. Losartan, an angiotensin II receptor blocker, can lead to a dry cough as a potential side effect. This occurs due to the drug's effect on the bradykinin pathway in the lungs. Monitoring for a dry cough is essential as it may indicate the need for further evaluation or medication adjustment to manage this adverse reaction.
4. A client with anxiety is prescribed alprazolam. What instruction should the nurse include in the client's teaching plan?
- A. Take this medication with food.
- B. Avoid activities that require alertness.
- C. Do not stop taking this medication abruptly.
- D. This medication may cause drowsiness.
Correct answer: C
Rationale: The correct answer is C: 'Do not stop taking this medication abruptly.' Alprazolam should not be stopped suddenly as it can lead to withdrawal symptoms. It is important for clients to taper off the medication gradually under medical supervision to prevent adverse effects. Choices A, B, and D are incorrect. Choice A is irrelevant to alprazolam administration instructions. Choice B, 'Avoid activities that require alertness,' is not the priority teaching point for alprazolam. Choice D, 'This medication may cause drowsiness,' is a common side effect of alprazolam but not the most critical instruction to include in the teaching plan.
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.
