HESI RN
HESI Pharmacology Practice Exam
1. A client with severe acne is seen in the clinic, and the healthcare provider prescribes isotretinoin. The nurse reviews the client's medication record and would contact the healthcare provider if the client is taking which medication?
- A. Vitamin A
- B. Digoxin (Lanoxin)
- C. Furosemide (Lasix)
- D. Phenytoin (Dilantin)
Correct answer: A
Rationale: Isotretinoin is a metabolite of vitamin A, which can lead to toxicity when taken together. Therefore, it is crucial to avoid concurrent use of vitamin A supplements with isotretinoin. Contacting the healthcare provider to discuss discontinuing vitamin A supplements is important to prevent potential adverse effects. Choices B, C, and D are incorrect as they are not known to interact significantly with isotretinoin.
2. A nurse starts classes for clients with type 2 diabetes. Which information would the nurse use as an outcome evaluation for the class?
- A. Parking convenience for attendees continues to be a major concern.
- B. Fasting blood glucose average readings were 20% lower by the end of classes.
- C. Discussion of food exchanges and calories was a well-attended class.
- D. Demonstrating the use of a blood glucose meter was an effective teaching strategy.
Correct answer: B
Rationale: A reduction in fasting blood glucose levels indicates the effectiveness of the diabetes management education provided. Monitoring blood glucose levels is a crucial aspect of diabetes management, and a decrease in average readings signifies improvement in managing blood sugar levels. Choices A, C, and D are not direct outcome evaluations related to the effectiveness of the education provided in managing diabetes. Parking convenience, attendance, and teaching strategies are not direct indicators of the impact on the clients' health outcomes.
3. A client is suspected of being poisoned and presents with symmetric, descending flaccid paralysis, blurred vision, double vision, and dry mouth. The nurse should consider these findings consistent with which potential bioterrorism agent?
- A. ricin
- B. botulism toxin
- C. sulfur mustard
- D. yersinia pestis
Correct answer: B
Rationale: The correct answer is B: botulism toxin. The symptoms described, including symmetric, descending flaccid paralysis, blurred vision, double vision, and dry mouth, are classic manifestations of botulism, which is caused by a toxin produced by Clostridium botulinum. This toxin affects the nervous system, leading to muscle weakness and paralysis. Choice A, ricin, typically presents with gastrointestinal symptoms and organ failure. Choice C, sulfur mustard, causes blistering skin and respiratory issues. Choice D, yersinia pestis, is associated with the plague and presents with fever, chills, weakness, and swollen lymph nodes.
4. The mother of a 4-month-old asks the nurse for advice in preventing diaper rash. What suggestion should the nurse provide?
- A. At diaper change generously powder the baby's diaper area with talcum powder to promote dryness.
- B. Wash the diaper area every 2 hours with soap and water to help prevent skin breakdown.
- C. Use a barrier cream, such as zinc oxide, which does not have to be completely removed with each diaper change.
- D. Place a cloth diaper inside the disposable diaper for overnight periods when increased wearing time is likely.
Correct answer: C
Rationale: Using a barrier cream like zinc oxide protects the skin and helps prevent diaper rash.
5. A client with hyperthyroidism is admitted for total thyroidectomy. What is the nurse's priority post-operative intervention?
- A. Monitor the client's calcium levels for hypocalcemia.
- B. Monitor for signs of respiratory distress.
- C. Administer oral calcium supplements.
- D. Elevate the head of the bed to 45 degrees.
Correct answer: A
Rationale: The correct answer is to monitor the client's calcium levels for hypocalcemia. After a total thyroidectomy, there is a risk of accidental removal or damage to the parathyroid glands, leading to hypocalcemia. This complication can manifest within the first 24-48 hours post-op. Monitoring calcium levels is crucial to prevent serious complications such as tetany or seizures. While monitoring for respiratory distress is important, it is not the priority in this case. Administering oral calcium supplements should only be done based on the healthcare provider's prescription and after assessing the client's calcium levels. Elevating the head of the bed to 45 degrees is beneficial for respiratory function but is not the priority intervention for a client at risk for hypocalcemia post-thyroidectomy.
