HESI Pharmacology Practice Exam
1. A client is receiving intravenous gentamicin (Garamycin). Which of the following findings should prompt the nurse to notify the healthcare provider immediately?
- A. Nausea
- B. Hearing loss
- C. Headache
- D. Diarrhea
Correct answer: B
Rationale: Gentamicin (Garamycin) is an aminoglycoside antibiotic known to cause ototoxicity, which can manifest as hearing loss. Hearing loss is a serious adverse effect that should be reported promptly to the healthcare provider to prevent further complications or adjust the treatment regimen. Nausea, headache, and diarrhea are common side effects of gentamicin but are not as severe or urgent as hearing loss in this context.
2. The client with type 2 DM is receiving dietary instructions from the nurse regarding the prescribed diabetic diet. The nurse determines that the client understands the instructions if the client states that:
- A. I need to skip meals if my blood glucose level is elevated.
- B. I need to eat a small meal or snack every 2 to 3 hours.
- C. I need to avoid using concentrated sweets in my diet.
- D. I need to eat a high-protein, low-carbohydrate diet.
Correct answer: C
Rationale: The correct answer is C: 'I need to avoid using concentrated sweets in my diet.' Clients with type 2 diabetes should avoid concentrated sweets as they can cause rapid spikes in blood glucose levels, which can be detrimental to their health. Option A is incorrect because skipping meals can lead to fluctuations in blood glucose levels. Option B is incorrect as it does not address the specific issue of avoiding concentrated sweets. Option D is incorrect because a high-protein, low-carbohydrate diet is not typically recommended as the primary approach for managing type 2 diabetes.
3. What instruction should the nurse include for a client prescribed nitroglycerin for a myocardial infarction?
- A. Take the medication only when experiencing severe chest pain.
- B. Store the medication in a dark container to protect it from light.
- C. Take the medication before engaging in physical activity that may trigger chest pain.
- D. Limit nitroglycerin use to no more than three doses in 15 minutes.
Correct answer: D
Rationale: The correct answer is D: 'Limit nitroglycerin use to no more than three doses in 15 minutes.' This instruction is crucial to prevent excessive use, which can lead to severe hypotension and other complications. Choice A is incorrect because nitroglycerin should also be used preventatively, not only during severe chest pain. Choice B is irrelevant and not a necessary instruction for nitroglycerin use. Choice C is incorrect as nitroglycerin is typically taken to prevent chest pain rather than waiting for an activity that may trigger it.
4. April, a 10-year-old admitted to inpatient pediatric care, has been getting more and more wound up and is losing self-control in the day room. Time-out does not appear to be an effective tool for April to engage in self-reflection. April’s mother admits to putting her in time-out up to 20 times a day. The nurse recognizes that:
- A. Time-out is an important part of April's baseline discipline.
- B. Time-out is no longer an effective therapeutic measure.
- C. April enjoys time-out and acts out to get some alone time.
- D. Time-out will need to be replaced with seclusion and restraint.
Correct answer: B
Rationale: The correct answer is B: 'Time-out is no longer an effective therapeutic measure.' In this scenario, the excessive use of time-out, up to 20 times a day, indicates that it is no longer effective in helping April self-reflect and control her behavior. Constant use of time-out without achieving the desired outcome suggests the need for alternative therapeutic interventions. Choice A is incorrect because the situation described indicates that time-out is not serving its intended purpose. Choice C is also incorrect as the behavior is not driven by a desire for alone time. Choice D is incorrect and inappropriate as seclusion and restraint should only be considered as a last resort and are not indicated based on the information provided.
5. When caring for a client with acute respiratory distress syndrome (ARDS), why does the nurse elevate the head of the bed 30 degrees?
- A. To reduce abdominal pressure on the diaphragm
- B. To promote oxygenation by improving lung expansion
- C. To encourage use of accessory muscles for breathing
- D. To drain secretions and prevent aspiration
Correct answer: D
Rationale: Elevating the head of the bed in a client with acute respiratory distress syndrome (ARDS) is essential to drain secretions and prevent aspiration. This position helps facilitate the removal of secretions from the airways, reducing the risk of aspiration pneumonia. Choices A, B, and C are incorrect as the primary reason for elevating the head of the bed in ARDS is to assist with secretion drainage and prevent complications associated with aspiration.
