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. Oxybutynin chloride (Ditropan XL) is prescribed for a client with neurogenic bladder. Which sign would indicate a possible toxic effect related to this medication?
- A. Pallor
- B. Drowsiness
- C. Bradycardia
- D. Restlessness
Correct answer: D
Rationale: Signs of toxicity related to oxybutynin chloride (Ditropan XL) include central nervous system excitation, such as nervousness, restlessness, hallucinations, and irritability. Other signs of toxicity may include hypotension or hypertension, confusion, tachycardia, a flushed or red face, and signs of respiratory depression. Restlessness is a sign of central nervous system excitation, which can indicate a possible toxic effect of this medication.
3. A client with rheumatoid arthritis is prescribed methotrexate. Which instruction should the nurse include in the client's teaching plan?
- A. Avoid taking folic acid supplements.
- B. Report any signs of infection immediately.
- C. Take the medication with a full meal.
- D. Limit fluid intake while on this medication.
Correct answer: B
Rationale: The correct instruction for the nurse to include in the client's teaching plan when taking methotrexate is to report any signs of infection immediately. Methotrexate can suppress the immune system, making the client more susceptible to infections. It is important for the client to promptly report any signs of infection to receive timely medical intervention. Choice A is incorrect because folic acid supplements are often recommended to reduce side effects of methotrexate. Choice C is incorrect as methotrexate is usually taken on an empty stomach unless the client experiences gastrointestinal upset. Choice D is incorrect as there is no need to limit fluid intake while on methotrexate; in fact, maintaining adequate fluid intake is important to prevent complications such as kidney damage.
4. A client is receiving vancomycin (Vancocin). Which of the following is the most important action for the nurse to take?
- A. Monitor the client for signs of nephrotoxicity.
- B. Monitor the client for signs of ototoxicity.
- C. Ensure adequate hydration.
- D. Administer the medication with food.
Correct answer: A
Rationale: The most important action for the nurse to take when a client is receiving vancomycin is to monitor for signs of nephrotoxicity. Vancomycin can cause kidney damage, so monitoring kidney function and signs of nephrotoxicity are crucial to prevent harm. While monitoring for ototoxicity and ensuring adequate hydration are important nursing actions, they are not as critical as preventing nephrotoxicity when administering vancomycin.
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.
