How many capsules should the LPN administer per dose?A.2 capsules B.1 capsule C.3 capsules D.4 capsules Rationale:To calculate: 500 mg ÷ 250 mg per capsule = 2 capsules per dose. This ensures the correct dose is administered every 8 hours.
3.A client receiving warfarin reports bleeding gums. What is the LPN’s priority action?HESI | LPN Pharmacology Exit Exam | Verified Prep Questions | Grade A | 100% Correct | 2025/2026 1 / 3

How many mL should the LPN administer per dose?A.0.5 mL B.1 mL C.0.25 mL D.2 mL Rationale:To calculate: 5,000 units ÷ 10,000 units/mL = 0.5 mL per dose. Accurate calculation prevents over- or under-dosing of heparin.
6.A client with type 2 diabetes is prescribed metformin. Which instruction should the LPN include in client teaching?A.“Take it with meals to reduce gastrointestinal upset.” B.“Take it on an empty stomach for better absorption.” C.“Stop taking it if you feel better.” D.“Expect immediate blood sugar control.” Rationale:Metformin is best taken with meals to minimize GI side effects like nausea and diarrhea, improving adherence.

8.A client is to receive 1,000 mL of 0.9% normal saline over 8 hours. The drop factor is 15 gtt/mL. What is the drip rate in gtt/min?A.31 gtt/min B.15 gtt/min C.60 gtt/min D.125 gtt/min Rationale:Calculate: (1,000 mL ÷ 8 hours) × (15 gtt/mL ÷ 60 min) = 125 mL/hr × 0.25 gtt/min/mL = 31.25 gtt/min, rounded to 31 gtt/min.
9.A client is prescribed prednisone for rheumatoid arthritis. Which adverse effect should the LPN monitor for?A.Weight gain B.Hypotension C.Hypoglycemia D.Hair loss Rationale:Prednisone, a corticosteroid, causes weight gain due to fluid retention and increased appetite, requiring monitoring.
