Rational use of antihypertensive medications in children | 1. An 8-year-old girl presents with obesity and stage I hypertension confirmed on repeat measurements in the clinic setting and at school. Initial screening laboratory tests were reassuring, with well-balanced electrolytes, normal renal function tests, and a normal urinalysis. Renal ultrasound with Doppler interrogation was unremarkable. An echocardiogram revealed no evidence of left ventricular hypertrophy. The most appropriate intervention at this time is: <br> a. Prescribe a thiazide diuretic <br> b. Prescribe an ACE inhibitor <br> c. Prescribe a beta-blocker <br> d. Provide appropriate counseling regarding therapeutic lifestyle modification | d |
Rational use of antihypertensive medications in children | 2. A 12-year-old boy is referred from urology with new-onset elevations in BP in the setting of known reflux nephropathy. In the clinic, his BP measurements fulfill criteria for stage II hypertension. Initial evaluations are notable for an estimated GFR of 65 ml/min/1.73m2 and 3+ proteinuria by dipstick. Which of the following drug classes would be considered most appropriate in this setting? <br> a. Thiazide diuretic <br> b. Calcium channel blocker <br> c. ACE inhibitor <br> d. Direct vasodilator | c |
Rational use of antihypertensive medications in children | 3. ACE Inhibitors and ARBs are absolutely contraindicated in patients with unilateral renal artery stenosis. <br> a. True <br> b. False | b |
Rational use of antihypertensive medications in children | 4. Which of the following medication classes should be avoided as primary therapy in the hypertensive athlete? <br> a. Diuretics <br> b. Beta-blockers <br> c. Calcium channel blockers <br> d. a and b | d |
Rational use of antihypertensive medications in children | 5. Most monogenic forms of hypertension are readily treated with calcium channel blockers. <br> a. True <br> b. False | b |
Renal consequences of parenteral nutrition | 1. The major indication for PN in children is: <br> a. Acute pancreatitis <br> b. Intestinal failure <br> c. Malnutrition in dialyzed patients <br> d. Burns | b |
Renal consequences of parenteral nutrition | 2. The composition of PN differs from that of EN in that PN does not contain: <br> a. Amino acids <br> b. Complex carbohydrate <br> c. Lipid <br> d. Arginine | b |
Renal consequences of parenteral nutrition | 3. In patients receiving PN, suppression of immune function may be a consequence of: <br> a. High sodium load <br> b. Inadequate vitamin content <br> c. High omega-6 to omega-3 polyunsaturated fatty acid ratio <br> d. Low glucose content | c |
Renal consequences of parenteral nutrition | 4. Intradialytic PN: <br> a. Is likely to be inadequate as a sole source of nutrition <br> b. Is routinely used in children in the UK <br> c. Is less well tolerated than standard PN <br> d. Can only be administered in small volumes due to risk of fluid overload | a |
Renal consequences of parenteral nutrition | 5. Electrolyte disturbances in patients receiving PN: <br> a. Are very uncommon since PN formulations have improved <br> b. Are only seen in patients receiving short-term PN <br> c. Are rarely affected by concurrent medications and co-morbidities <br> d. Are potentially avoidable | d |
Renal consequences of parenteral nutrition | 6. Renal stone disease in patients receiving PN: <br> a. Is exclusive to patients with intestinal failure <br> b. Is a consequence of the high pH of PN formulations <br> c. May be a consequence of low calcium intake, vitamin D administration, and hyperparathyroidism <br> d. Are usually due to infection | c |

Description: This dataset comprises multiple-choice questions from the "Educational Review" articles published by the journal Pediatric Nephrology between January 2014 and April 2024. Each entry in the dataset includes the context of the question, the question itself, and the correct answer. This dataset is designed to evaluate the performance of large language models (LLMs) like ChatGPT-4o and Gemini 1.5 in the field of pediatric nephrology.
