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 atrial fibrillation is prescribed digoxin. The nurse should monitor for which potential side effect?
- A. Bradycardia
- B. Tachycardia
- C. Headache
- D. Hyperglycemia
Correct answer: A
Rationale: The correct answer is A: Bradycardia. Digoxin can lead to bradycardia due to its effect on slowing down the heart rate, which can be dangerous in a client with atrial fibrillation. Monitoring the client's heart rate is essential to detect and manage this potential side effect. Choices B, C, and D are incorrect because digoxin is not known to cause tachycardia, headache, or hyperglycemia as common side effects.
3. A client with bipolar disorder is taking lithium. Which client assessment data would indicate a potential adverse effect of lithium therapy?
- A. Increased appetite
- B. Dry mouth and increased thirst
- C. Tremors and polyuria
- D. Constipation
Correct answer: B
Rationale: When assessing a client taking lithium, dry mouth and increased thirst are indicators of potential adverse effects. Lithium can lead to nephrogenic diabetes insipidus, causing polyuria and subsequent increased thirst due to impaired water reabsorption in the kidneys. Tremors can also be a sign of lithium toxicity. Monitoring and recognizing these symptoms are crucial in managing lithium therapy and preventing further complications.
4. A client with a history of stroke is prescribed clopidogrel. The nurse should monitor the client for which potential side effect?
- A. Bleeding
- B. Bruising
- C. Nausea
- D. Headache
Correct answer: A
Rationale: Clopidogrel is an antiplatelet medication that works to prevent blood clots, but it can also increase the risk of bleeding. Therefore, the nurse should monitor the client for signs of bleeding, such as easy bruising, prolonged bleeding from cuts, blood in urine or stool, or unusual bleeding from the gums. Prompt identification and management of bleeding are crucial to prevent complications. Choices B, C, and D are incorrect because while bruising and other symptoms can occur as a result of bleeding, they are not the primary side effect to monitor for with clopidogrel. Nausea and headache are less commonly associated with clopidogrel use compared to bleeding.
5. A client with chronic kidney disease is prescribed darbepoetin alfa. The nurse should monitor for which potential side effect?
- A. Hypertension
- B. Hypotension
- C. Hyperkalemia
- D. Hyperglycemia
Correct answer: A
Rationale: The correct answer is A: Hypertension. Darbepoetin alfa, used to treat anemia in chronic kidney disease, can lead to hypertension as a side effect. This medication stimulates red blood cell production, which can increase blood pressure. Monitoring blood pressure regularly is crucial to detect and manage this potential adverse effect. Choices B, C, and D are incorrect because hypotension, hyperkalemia, and hyperglycemia are not commonly associated with darbepoetin alfa therapy in chronic kidney disease.
