HESI Pharmacology Practice Exam
1. The clinic nurse is reviewing a teaching plan for a client receiving antineoplastic medication. When implementing the plan, the nurse should advise the client:
- A. To take aspirin (acetylsalicylic acid) as needed for a headache
- B. To avoid drinking beverages containing alcohol
- C. To consult with healthcare providers (HCPs) before receiving immunizations
- D. That it is necessary to consult HCPs before receiving a flu vaccine at the local health fair
Correct answer: C
Rationale: The correct advice for a client receiving antineoplastic medication is to consult with healthcare providers (HCPs) before receiving immunizations. Antineoplastic medications can lower the body's resistance, making it crucial to seek guidance from healthcare providers to prevent potential complications that may arise due to the medication's impact on the immune system. Choices A, B, and D are incorrect because taking aspirin for a headache, avoiding alcohol, and consulting only before a flu vaccine at a local health fair do not directly address the specific risk related to antineoplastic medications and immunizations.
2. The client has a PRN prescription for ondansetron (Zofran). For which condition should this medication be administered to the postoperative client?
- A. Paralytic ileus
- B. Incisional pain
- C. Urinary retention
- D. Nausea and vomiting
Correct answer: D
Rationale: Ondansetron, also known as Zofran, is an antiemetic medication primarily used to treat nausea and vomiting. In the postoperative setting, it is commonly administered to manage postoperative nausea and vomiting, which are frequent occurrences after surgery. Ondansetron works by blocking serotonin, a natural substance in the body that can trigger nausea and vomiting. It is also utilized to manage chemotherapy-induced nausea and vomiting. Therefore, the correct condition for which ondansetron should be administered to the postoperative client is nausea and vomiting.
3. A client is to begin a 6-month course of therapy with isoniazid (INH). A nurse plans to teach the client to:
- A. Avoid drinking alcohol.
- B. Report yellow eyes or skin immediately.
- C. Avoid Swiss or aged cheeses.
- D. Avoid vitamin supplements during therapy.
Correct answer: B
Rationale: When a client is on isoniazid (INH) therapy, they should be instructed to report any signs of hepatitis, such as yellowing of the eyes or skin, immediately. Alcohol consumption should be avoided during INH therapy due to the risk of hepatotoxicity. Foods high in tyramine, such as Swiss or aged cheeses, should also be avoided to prevent adverse reactions. Additionally, while on INH therapy, it is essential to avoid vitamin supplements containing pyridoxine (vitamin B6) to prevent potential interactions.
4. The client has been taking omeprazole (Prilosec) for 4 weeks. The ambulatory care nurse evaluates that the client is receiving the optimal intended effect of the medication if the client reports the absence of which symptom?
- A. Diarrhea
- B. Heartburn
- C. Flatulence
- D. Constipation
Correct answer: B
Rationale: Omeprazole, a proton pump inhibitor, is used as an antiulcer agent to reduce gastric acid secretion. The optimal intended effect of omeprazole is the relief of pain and discomfort associated with gastric irritation, commonly referred to as heartburn. Therefore, the absence of heartburn indicates that the medication is working effectively in managing the client's gastric condition.
5. A client with hypertension is prescribed clonidine (Catapres) transdermal patch. Which statement by the client indicates an understanding of the medication?
- A. I should change the patch daily.
- B. I should remove the old patch before applying a new one.
- C. I should avoid alcohol consumption while using this patch.
- D. I should apply the patch to different sites each time.
Correct answer: B
Rationale: The correct answer is B. The client should remove the old clonidine (Catapres) patch before applying a new one to prevent overdose. The patch is typically changed every 7 days. Avoiding alcohol consumption is important as it can potentiate the sedative effects of clonidine. It is recommended to rotate application sites to prevent skin irritation and ensure optimal drug absorption.
