Question 1 of 5
A nurse is preparing to administer enoxaparin 0.75 mg/kg subcutaneously to a client who weighs 154 lb. The amount available is enoxaparin 60 mg/0.6 mL. How many mL should the nurse administer?
Correct Answer: B
Rationale:
To calculate the dose of enoxaparin, first convert the client's weight from pounds to kilograms: 154 lb/2.2 = 70 kg.
Then, calculate the dose: 0.75 mg/kg x 70 kg = 52.5 mg. Since the concentration is 60 mg/0.6 mL, divide the dose needed by the concentration: 52.5 mg/60 mg x 0.6 mL = 0.5 mL.
Therefore, the correct answer is B (0.5 mL).
Choice A is incorrect as it is less than the calculated dose.
Choice C is incorrect as it is based on the concentration but does not match the calculated dose.
Choice D is incorrect as it is higher than the calculated dose.
