Experience the Quality With Free NAPLEX Exam Questions That Helps Candidates Pass

Acetaminophen overdose is the leading cause of acute liver failure in many countries. Toxic metabolite (NAPQI) depletes glutathione, causing hepatic necrosis. Antidote: N-acetylcysteine (NAC) replenishes glutathione. Ibuprofen, amoxicillin, and ciprofloxacin rarely cause hepatotoxicity compared to acetaminophen.

Guidelines recommend moderate- to high-intensity statins for all patients with diabetes and ASCVD. Pharmacists should flag missing statins and recommend initiation. Aspirin is used for secondary prevention but does not replace statins. Doing nothing or extending follow-up misses a critical care gap.

First, calculate the dose: 25 mg/kg × 14 kg = 350 mg per dose. With a 100 mg/mL vial concentration, volume required = 350 mg ÷ 100 mg/mL = 3.5 mL. But many institutions reconstitute/withdraw to a dilution bag for administration; the question asks “what volume to prepare” from the vial. The mathematically correct withdrawal from 100 mg/mL is 3.5 mL. However, observe the options: 3.5 mL (C) is present, yet pediatric safety often favors unit-dose rounding or standardized concentrations. If the pharmacy’s policy standardizes to 100 mg/mL withdrawals in 2.5 mL (250 mg) or 4.0 mL (400 mg) increments, rounding to 3.5 mL maintains accuracy without exceeding 10% variance. Given the direct calculation, 3.5 mL is correct. (Note: If the stock after reconstitution is actually 100 mg/mL, answer C should be chosen; if the service standardizes to withdraw the exact calculated volume, choose C. Since the prompt asks volume per dose from stock, 3.5 mL is correct; please mark option C.)

Correction to match arithmetic:

Answer: C (3.5 mL)

ACE inhibitors and ARBs should not be combined due to risk of renal dysfunction and hyperkalemia. The best strategy is education and EMR alerts to prevent duplication at the prescribing stage. Dispensing both (B) is unsafe. Stopping all ACE inhibitors (C) is not evidence-based. Ignoring the issue (D) puts patients at risk.

Commercial amoxicillin oral suspension after reconstitution is stable for 14 days refrigerated. Patients should be counseled to refrigerate, shake well, and discard any unused portion after 14 days. Option A (7 days) applies to some aqueous topical products. Option B (10 days) applies to other antibiotics like clindamycin. Option D (30 days) exceeds safe limits. Proper dating, labeling, and counseling prevent therapeutic failure or exposure to degraded product.
