The most common urodynamic findings in patients with Parkinson disease with lower urinary tract dysfunction is

Correct Answer: C

Rationale: Parkinson's LUT dysfunction commonly shows detrusor overactivity (DO) basal ganglia loss causes uninhibited contractions, urgency. Sphincter dyssynergia is spinal (e.g., MS) not Parkinson's. Bradykinesia affects voluntary sphincter less urodynamic. Impaired contractility is late DO predominates. Overactivity distinguishes it, key to Parkinson's bladder issues, unlike spinal or contractile findings.

Correct Answer: C

Rationale: Karnofsky score of 60 fits needs occasional help but manages most needs (e.g., 8 cm RCC, functional). 40 is bedridden too low. 50 requires frequent care overstated. 70 is near-normal underestimates impact. 60 distinguishes it, key to performance status in cancer, unlike severe or mild extremes.

Correct Answer: A

Rationale: Primary mediastinal NSGCTs aren't more chemo-sensitive poor response, worse prognosis than testicular NSGCTs false. Poor prognosis true, aggressive. Yolk sac components common correct, marker rise. Klinefelter link accurate, genetic risk. Lower chemo sensitivity distinguishes the error, key to its challenging management, unlike prognosis, histology, or association truths.

Correct Answer: B

Rationale: BMI >30<35 isn't absolute relative risk (surgery complications), manageable. Morbid obesity (>35) is absolute high perioperative risk. BMI <20 signals malnutrition poor healing, absolute. Anuria (no urine) reflects ESRD transplant candidate, not barrier. Moderate BMI distinguishes it, critical for candidacy flexibility, unlike severe or extreme limits.

Correct Answer: C

Rationale: Prophylaxis for hydronephrosis uses half therapeutic dose prevents UTI (e.g., amoxicillin neonates, TMP-SMX >2 months), true. Amoxicillin fits neonates correct. TMP-SMX suits older infants standard. Evening dosing aids compliance accurate. Half-dose distinguishes it, key to prophylaxis strategy, unlike drug or timing options all true.
