1. Which of the following diuretics inhibits sodium reabsorption in the kidneys while sparing K+ and hydrogen ions?
- A. Spironolactone
- B. Furosemide
- C. Hydrochlorothiazide
- D. Bumetanide
Correct answer: A
Rationale: Spironolactone is the correct answer as it is classified as a potassium-sparing diuretic. It works by inhibiting sodium reabsorption in the kidneys while promoting the retention of potassium and hydrogen ions. This mechanism of action helps in reducing fluid retention without causing excessive loss of potassium, which is a common side effect of other diuretics. Furosemide (choice B), Hydrochlorothiazide (choice C), and Bumetanide (choice D) are not correct as they are not potassium-sparing diuretics. Furosemide and Bumetanide are loop diuretics that inhibit sodium, potassium, and chloride reabsorption in the loop of Henle. Hydrochlorothiazide is a thiazide diuretic that inhibits sodium and chloride reabsorption in the distal convoluted tubule, leading to potassium loss.
2. How should the oral form of albuterol be taken?
- A. Administer with meals to minimize gastric irritation
- B. Administer before meals with water
- C. Administer after meals with water
- D. Administer in the morning with milk
Correct answer: A
Rationale: The correct way to take oral albuterol is with meals to minimize gastric irritation. Taking it with food can help reduce the risk of stomach upset that may occur when the medication is taken on an empty stomach. This approach can improve tolerability and adherence to the treatment regimen. Choices B, C, and D are incorrect because taking albuterol before meals, after meals, or in the morning with milk does not address the issue of minimizing gastric irritation, which is a common side effect of the medication.
3. A client is starting therapy with raloxifene. Which adverse effect should the client monitor for as instructed by the nurse?
- A. Leg cramps
- B. Hot flashes
- C. Urinary frequency
- D. Hair loss
Correct answer: B
Rationale: Hot flashes are a common adverse effect associated with raloxifene therapy. Raloxifene is a selective estrogen receptor modulator (SERM) used to prevent and treat osteoporosis in postmenopausal women. Hot flashes are a well-known side effect of SERMs due to their estrogen-like effects on the body. Leg cramps, urinary frequency, and hair loss are not typically associated with raloxifene therapy. Therefore, the nurse should instruct the client to monitor for hot flashes as part of the medication education.
4. A client is undergoing preparation for extensive colorectal surgery. Which of the following oral antibiotics should be administered to suppress normal flora in the GI tract?
- A. Kanamycin
- B. Gentamicin
- C. Neomycin
- D. Tobramycin
Correct answer: C
Rationale: The correct answer is C: Neomycin. Neomycin, an aminoglycoside antibiotic, is administered orally before GI surgery to eliminate the normal flora in the large intestine. This helps reduce the risk of postoperative infections by decreasing the bacterial load in the gut. Choices A, B, and D (Kanamycin, Gentamicin, Tobramycin) are not typically used to suppress normal flora in the GI tract before colorectal surgery.
5. A healthcare provider is reviewing a client's health record and notes that the client is experiencing episodes of hypokalemia. Which of the following medications should the healthcare provider identify as a cause of the client's hypokalemia?
- A. Captopril
- B. Lisinopril
- C. Furosemide
- D. Spironolactone
Correct answer: C
Rationale: Furosemide is a loop diuretic that acts on the kidneys to increase urine production. This increased urine output can lead to the excessive excretion of potassium, resulting in hypokalemia. Monitoring potassium levels and considering supplementation may be necessary when a patient is on furosemide to prevent or manage hypokalemia.
