1. A client has an infection and a prescription for gentamicin intermittent IV bolus every 8 hr. A peak and trough is required with the next dose. Which of the following actions should be taken to obtain an accurate gentamicin serum level?
- A. Draw a trough level immediately prior to administering the medication and a peak level 30 min after the dose.
- B. Draw a peak level 90 min prior to administering the medication and a trough level 90 min after the dose.
- C. Draw a trough level immediately prior to administering the medication and a peak level 30 min after the dose.
- D. Draw a peak level at 0900 and a trough level at 2100.
Correct answer: C
Rationale: To obtain an accurate gentamicin serum level, the trough should be drawn immediately before administering the medication, and the peak level should be drawn 30 minutes after the dose. This timing allows for the assessment of the lowest and highest drug concentrations in the bloodstream, ensuring therapeutic levels are achieved while minimizing the risk of toxicity. Choice A is correct as it follows this timing protocol. Choices B and D have incorrect timing for peak and trough levels, which would not provide an accurate representation of the drug's concentration in the bloodstream.
2. A client with peptic ulcer disease is being taught about managing the condition. Which of the following statements indicates an understanding of the teaching?
- A. I should eat small, frequent meals that are low in fiber.
- B. I will limit my intake of caffeine-containing beverages.
- C. I should take NSAIDs to relieve my pain.
- D. I will drink milk before bedtime to decrease acid production.
Correct answer: B
Rationale: The correct answer is B: 'I will limit my intake of caffeine-containing beverages.' Limiting intake of caffeine-containing beverages is important for managing peptic ulcer disease as caffeine can stimulate gastric acid secretion, which may worsen the condition. It is advisable to choose decaffeinated beverages and avoid caffeinated drinks to help reduce the risk of aggravating the ulcer. Choices A, C, and D are incorrect. Choice A suggests eating small, frequent meals low in fiber, which is not ideal for managing peptic ulcer disease. Choice C of taking NSAIDs is contraindicated as NSAIDs can worsen peptic ulcers. Choice D of drinking milk before bedtime to decrease acid production is a common misconception; while milk may temporarily neutralize stomach acid, it can stimulate more acid production later, making the condition worse.
3. A client with heart failure is being instructed on laxative use. Which of the following laxatives should the client avoid?
- A. Sodium phosphate
- B. Psyllium
- C. Bisacodyl
- D. Polyethylene glycol
Correct answer: A
Rationale: The correct answer is A: Sodium phosphate. Clients with heart failure often follow a sodium-restricted diet. Sodium phosphate laxatives can lead to sodium absorption, causing fluid retention, which is contraindicated in heart failure. It is crucial to avoid sodium phosphate laxatives in these clients to prevent exacerbation of fluid overload and heart failure symptoms. Psyllium (choice B), Bisacodyl (choice C), and Polyethylene glycol (choice D) are not contraindicated in clients with heart failure and can be used safely for bowel management.
4. A client has a new prescription for Enalapril. Which of the following adverse effects should the nurse monitor?
- A. Dry cough
- B. Weight gain
- C. Diarrhea
- D. Nausea
Correct answer: A
Rationale: Corrected Rationale: Enalapril, an ACE inhibitor, commonly causes a persistent dry cough as an adverse effect. The nurse should closely monitor the client for this and instruct them to report it to the healthcare provider if it occurs. Choices B, C, and D are incorrect as weight gain, diarrhea, and nausea are not commonly associated adverse effects of Enalapril.
5. A client has a new prescription for Hydrochlorothiazide. Which of the following instructions should the nurse include?
- A. Take the medication in the morning.
- B. Increase your intake of potassium-rich foods.
- C. Expect decreased urination within the first few days.
- D. Avoid foods high in potassium.
Correct answer: B
Rationale: The correct answer is B: 'Increase your intake of potassium-rich foods.' Hydrochlorothiazide is a diuretic that can lead to hypokalemia by increasing potassium excretion. Therefore, instructing the client to increase their intake of potassium-rich foods is essential to prevent electrolyte imbalances and support overall health. Choices A, C, and D are incorrect. Instructing the client to take the medication in the morning is not directly related to the medication's mechanism of action. Expecting decreased urination within the first few days is not accurate as the medication is a diuretic that typically increases urination. Also, advising the client to avoid foods high in potassium would not be suitable, as increasing potassium-rich foods is necessary to counteract potential potassium depletion caused by Hydrochlorothiazide.
