Which is not a recommended regimen for treatment of UTI in the non pregnant woman?

Correct Answer: D

Rationale: Nitrofurantoin 50 mg QID for 5 days isn't standard dose is low (typically 100 mg), and 3-day courses suffice for uncomplicated UTI, not recommended. Trimethoprim 300 mg daily, Augmentin duo BD, and cephalexin 500 mg BD for 5 days align effective options. Nitrofurantoin's dosing/duration distinguishes it, key to guideline adherence, unlike appropriate regimens.

Correct Answer: D

Rationale: Grade 4 renal injury includes deep laceration to the collecting system urine leak (e.g., pelvis breach), per AAST scale. Grade 1 is contusion superficial. Grade 2 is <1 cm laceration no collecting system. Grade 3 is >1 cm parenchyma only. Grade 4's depth distinguishes it, critical for trauma staging, unlike lesser grades.

Correct Answer: D

Rationale: Urine osmolality <500 mOsm/kg isn't pre-renal ARF should be >500, concentrating urine (e.g., hypoperfusion), incorrect. Decreased GFR perfusion drop, true. High specific gravity concentrated, correct. Urinary sodium <10 reabsorption, accurate. High osmolality distinguishes pre-renal, key to hypoperfusion response, unlike dilute error.

Correct Answer: D

Rationale: Cimetidine doesn't falsely cause hematuria beetroot, raspberries, rhubarb mimic blood (pigments), common confounders. Cimetidine (H2-blocker) lacks urinary discoloration true negative. Non-false status distinguishes it, critical for hematuria evaluation, unlike dietary mimics.

Correct Answer: C

Rationale: Ice-water enema isn't appropriate for priapism no evidence, ineffective vs. ischemic (e.g., sickle cell). Terbutaline (β-agonist), aspiration (decompression), and Neo-Synephrine (vasoconstriction) target corpora standard. Lack of efficacy distinguishes enema, key to priapism management, unlike proven interventions.
