Question 1 of 5
Thiazide diuretics may produce an increase in blood levels of uric acid and:
Correct Answer: D
Rationale: Thiazide diuretics can lead to hyperglycemia by reducing insulin sensitivity. This can result in increased blood glucose levels. Thiazides also elevate uric acid levels by reducing its excretion. Therefore, the correct answer is D (Glucose). Incorrect choices: A (Potassium) - Thiazides typically cause hypokalemia, not hyperkalemia. B (BUN) and C (Urea) - Thiazides may cause a slight increase in BUN and serum creatinine levels due to reduced kidney function, but not as significantly as glucose levels.
Question 2 of 5
A patient is being treated with furosemide and Digoxin because of CHF. She developed UTI. Which of the following antibiotics should NOT be prescribed?
Correct Answer: C
Rationale: The correct answer is C: Gentamycin. Gentamycin is known to have potential nephrotoxicity, which can exacerbate renal dysfunction caused by furosemide. It should be avoided in patients with CHF and UTI. Cotrimoxazole (A) can be used with caution, Ciprofloxacin (B) is generally safe, and Ampicillin (D) is a suitable choice for UTI treatment in this scenario.
Question 3 of 5
The primary role of the phosphate buffer system is to?
Correct Answer: C
Rationale: The correct answer is C: limit pH changes caused by metabolic and fixed acids. 1. Phosphate buffer system consists of dihydrogen phosphate (H2PO4-) and hydrogen phosphate (HPO4^2-) ions, which can donate or accept H+ ions to maintain a stable pH. 2. Metabolic and fixed acids produced in the body can lead to pH changes. The phosphate buffer system helps to prevent drastic changes in pH by neutralizing excess H+ ions. 3. Options A, B, and D are incorrect because the phosphate buffer system is not specifically designed to buffer stomach acid, carbonic acid formed by carbon dioxide, or buffer the urine.
Question 4 of 5
Which of the following hormones is secreted by corpus albicans?
Correct Answer: D
Rationale: The correct answer is D because the corpus albicans is the end stage of the corpus luteum, which degenerates if fertilization does not occur. As a result, it no longer secretes hormones. Estrogen and progesterone are secreted by the corpus luteum, not the corpus albicans. Luteinizing hormone is produced by the anterior pituitary gland, not by the corpus albicans.
Question 5 of 5
A patient with cancer of the bladder has just returned
Correct Answer: A
Rationale: The correct answer is A because after surgery to create an ileal conduit for bladder cancer, monitoring urine output is crucial to assess kidney function and ensure proper drainage. Hourly monitoring helps to detect any complications early. Choice B is incorrect as it does not provide any relevant information. Choice C is incorrect because monitoring urine output is essential postoperatively. Choice D is incorrect as it does not address the immediate postoperative care needs of a patient with an ileal conduit.
