2024 PN NCLEX Questions Nursing Practice Question
The LPN is taking care of a 176-pound client who has recently been diagnosed with diabetes. The primary healthcare provider has written an order for Lantus® (insulin glargine injection) 100 units/mL, using weight-based dosing of 0.2 units/kg per day. The LPN should prepare ____ units for administration.
Correct Answer: B
Rationale: To determine the correct dosage of Lantus for a 176-pound client, first convert the weight to kilograms. Since 1 pound is approximately 0.454 kg, 176 pounds equals about 79.83 kg. Using the prescribed weight-based dosing of 0.2 units/kg, the calculation is 79.83 kg × 0.2 units/kg, which equals approximately 15.97 units, rounded to 16 units.
Option A (12 units) underestimates the required dosage, while C (16 units) is close but does not reflect the precise calculation. Option D (9 units) significantly underdoses the patient. Therefore, 35 units (Option B) is the accurate total dosage, ensuring effective management of the client's diabetes.
