1. A client has a prescription for Amphotericin B. Which of the following laboratory values should be monitored by the nurse to assess for an adverse effect of this medication?
- A. Serum creatinine.
- B. Serum potassium.
- C. Serum sodium.
- D. Serum calcium.
Correct answer: A
Rationale: Corrected Rationale: Amphotericin B is known to cause nephrotoxicity, a potential adverse effect that can be monitored by checking the client's serum creatinine levels. Regular monitoring of serum creatinine helps in early identification of kidney damage and allows for timely intervention to prevent further complications. Choice B, serum potassium, is not typically associated with adverse effects of Amphotericin B. Choice C, serum sodium, and choice D, serum calcium, are not directly affected by Amphotericin B and are not primary indicators of its adverse effects.
2. Potassium-sparing diuretics primarily affect which part of the kidney?
- A. Proximal convoluted tubule
- B. Loop of Henle
- C. Collecting duct
- D. Distal convoluted tubule
Correct answer: D
Rationale: Potassium-sparing diuretics exert their primary effects on the distal convoluted tubule in the kidney. By acting on this specific part of the nephron, these diuretics promote sodium excretion while sparing potassium, thus helping to maintain potassium levels in the body. This mechanism differs from other diuretics that may cause potassium loss as a side effect. Understanding the site of action of potassium-sparing diuretics is crucial in clinical practice for managing conditions like hypertension and edema where diuresis is necessary without the risk of hypokalemia.
3. When teaching a client with a prescription for Vancomycin, which instruction should the nurse include?
- A. Expect red man syndrome during treatment.
- B. Take the medication with a full glass of water.
- C. Increase your intake of potassium-rich foods.
- D. Monitor for hearing loss while taking this medication.
Correct answer: D
Rationale: The correct answer is D. Vancomycin is known to cause ototoxicity, which can result in hearing loss. Therefore, it is important for clients to monitor for any changes in their hearing while taking this medication and promptly report any issues to their healthcare provider for further evaluation and management. Choices A, B, and C are incorrect because red man syndrome is associated with rapid infusion of Vancomycin, not a common side effect during treatment; taking the medication with a full glass of water is a general instruction for many medications but not specific to Vancomycin; and increasing potassium-rich foods is not directly related to Vancomycin therapy.
4. Which of the following is commonly used to treat migraine headaches?
- A. Beta-blockers
- B. Cholinesterase Inhibitors
- C. ACE inhibitors
- D. Anti-epileptic drugs (AEDs)
Correct answer: D
Rationale: Anti-epileptic drugs (AEDs) are often used in the management of migraine headaches due to their ability to help prevent or reduce the frequency and intensity of migraines. They work by stabilizing electrical activity in the brain, which can help in controlling migraine symptoms. While beta-blockers are also sometimes used in migraine prevention, anti-epileptic drugs are more commonly associated with migraine treatment. Cholinesterase Inhibitors are not typically used for migraine headaches, as they are more commonly associated with conditions like Alzheimer's disease. ACE inhibitors are a type of medication used to treat conditions like high blood pressure and heart failure, but they are not a first-line treatment for migraines.
5. When should a patient taking omeprazole be administered the medication?
- A. Before bedtime
- B. After dinner
- C. In the morning on an empty stomach
- D. With the patient's lunch meal
Correct answer: C
Rationale: Omeprazole should be administered in the morning on an empty stomach to maximize its effectiveness. This timing is important as omeprazole works best when taken before a meal to inhibit acid production by the stomach. Taking it on an empty stomach in the morning allows the medication to be absorbed efficiently and provides optimal therapeutic effects throughout the day. Choices A, B, and D are incorrect because taking omeprazole before bedtime, after dinner, or with lunch may not allow the medication to work effectively as it requires an empty stomach for better absorption and action.
