Question 1 of 5

A client who weighs 60 kg receives a prescription for dalteparin 200 units/kg subcutaneously once a day for a month. The medication is available in 25,000 units/mL vial. How many mL should the nurse administer?(Enter numerical value. If rounding is required, round to the nearest tenth.)

Correct Answer: 0.5

Rationale:
To find the answer, we can use the following steps: Calculate the dose of dalteparin in units by multiplying the weight in kg by the dosage in units/kg. Divide the dose in units by the concentration in units/mL. Round the result to the nearest tenth. Using these steps, we get: (dose in units) = (60) x (200) = 12,000 units. (volume in mL) = (12,000) / (25,000) = 0.48 mL. (rounded volume in mL) = 0.5 mL.
Therefore, the nurse should administer 0.5 mL of dalteparin from the vial to the client.
