HESI RN
HESI Pharmacology Practice Exam
1. A nurse preparing a client for surgery reviews the client's medication record. The client is to be nothing per mouth (NPO) after midnight. Which of the following medications, if noted on the client's record, should the nurse question?
- A. Cyclobenzaprine (Flexeril)
- B. Alendronate (Fosamax)
- C. Allopurinol (Zyloprim)
- D. Prednisone
Correct answer: D
Rationale: Prednisone is a corticosteroid that can cause adrenal atrophy, reducing the body's ability to withstand stress. During surgery, the dosage may need to be adjusted due to its impact on the body's stress response. Choices A, B, and C are not typically contraindicated before surgery and do not have the same potential impact on the body's stress response.
2. What is one of the roles of the oxytocin hormone?
- A. Stimulates milk ejection.
- B. Stimulates the production of milk.
- C. Stimulates the development of lactoferrin.
- D. Stimulates the secretion of relaxin.
Correct answer: A
Rationale: The correct answer is A: 'Stimulates milk ejection.' Oxytocin is responsible for contracting the muscles around the milk ducts, pushing milk into the nipples for breastfeeding. This process is known as milk ejection or let-down. The other choices are incorrect because oxytocin's primary function is to facilitate milk ejection rather than directly stimulating the production of milk, the development of lactoferrin, or the secretion of relaxin.
3. During an acute exacerbation of asthma, what is the nurse's first action for a client experiencing this condition?
- A. Administer a bronchodilator as prescribed.
- B. Check the client's oxygen saturation.
- C. Reassure the client and encourage deep breathing.
- D. Provide emotional support to reduce anxiety.
Correct answer: A
Rationale: The correct first action when managing an acute exacerbation of asthma is to administer a bronchodilator as prescribed. Bronchodilators help open the airways and improve breathing in individuals experiencing an asthma exacerbation. Checking oxygen saturation (Choice B) is important but not the first action. Reassuring the client and encouraging deep breathing (Choice C) can be beneficial but should come after administering the bronchodilator. Providing emotional support to reduce anxiety (Choice D) is important but is not the initial priority in managing an acute exacerbation of asthma.
4. A 14-year-old with a history of sickle cell disease is admitted to the hospital with a diagnosis of vaso-occlusive crisis. Which statement by the client would be most indicative of the etiology of this crisis?
- A. I knew this would happen. I've been eating too much red meat lately.
- B. I really enjoyed my fishing trip yesterday. I caught 2 fish.
- C. I have really been working hard practicing with the debate team at school.
- D. I went to the healthcare provider last week for a cold, and I have gotten worse.
Correct answer: D
Rationale: The correct answer is D because a recent illness, such as a cold, can trigger a vaso-occlusive crisis in sickle cell disease. This crisis is often precipitated by infections or other illnesses that cause a systemic inflammatory response, leading to vaso-occlusion. Choices A, B, and C do not directly relate to the etiology of a vaso-occlusive crisis in sickle cell disease, making them incorrect.
5. A nurse assesses a client who is recovering from a nephrostomy. Which assessment findings should alert the nurse to urgently contact the healthcare provider? (Select all that apply.)
- A. Foul-smelling drainage
- B. Bloody drainage at site
- C. A & B
- D. All of the above
Correct answer: C
Rationale: After a nephrostomy, the nurse should assess the client for complications and urgently notify the provider if there is foul-smelling drainage, bloody drainage at the site, or both. Foul-smelling drainage can indicate infection, while bloody drainage may suggest bleeding. Clear drainage is generally normal after a nephrostomy. A headache would not typically be directly related to nephrostomy complications. Therefore, options A and B are correct choices for urgent notification, making option C the correct answer.
