Question 1 of 5
A nurse is caring for a client who is postoperative hip arthroplasty and has a new prescription for enoxaparin 1 mg/kg/dose subcutaneous every 12 hr. The client weighs 95 lbs. How many mg should the nurse administer per dose?
Correct Answer: A
Rationale: The correct answer is A: 43.1 mg.
To calculate the dose of enoxaparin, you first convert the client's weight from pounds to kilograms (95 lbs รท 2.2 = 43.18 kg).
Then, you multiply the weight in kilograms by the prescribed dose of 1 mg/kg to get the total dose (43.18 kg x 1 mg/kg = 43.18 mg). Since the prescription is every 12 hours, you administer the calculated dose of 43.18 mg per dose, which rounds to 43.1 mg.
Summary of other choices:
B-G: Since the correct calculation involves converting the weight to kilograms and multiplying by 1 mg/kg, the other choices are incorrect as they do not follow this logical calculation process.
