(Enter numerical value only. If rounding is required, round to the nearest tenth.)
The Correct Answer is ["1.85"]
The healthcare provider prescribes lorazepam at a dose of 50 mcg/kg intramuscularly 2 hours before a scheduled procedure for a client who weighs 74 kg.
The client should receive 3700 mcg of lorazepam (50 mcg/kg * 74 kg). Since 1 mg is equivalent to 1000 mcg, 3700 mcg is equivalent to 3.7 mg.
The medication is available in a 2 mg/mL vial, so the nurse should administer 1.85 mL of medication (3.7 mg / 2 mg/mL).

Explanation
The client is currently receiving an infusion labeled as 5% Dextrose Injection 500 mL with heparin sodium 25,000 Units. The concentration of heparin in the IV solution is 50 units/mL (25,000 units / 500 mL).
A prescription is received to change the rate of the infusion to heparin 1,000 units/hour.
Since the concentration of heparin in the IV solution is 50 units/mL, the nurse should program the infusion pump to deliver 20 mL/hour of the IV solution (1,000 units/hour / 50 units/mL).
Correct Answer is ["239"]
Explanation
The child receives a prescription for asparaginase 4,780 IU IV.
The vial is labeled "Asparaginase 10,000 IU single-use vial" and for IV use, it should be reconstituted in 5 mL.
Since the child needs 4,780 IU of asparaginase and the vial contains 10,000 IU, the nurse should administer 2.39 mL of medication (4,780 IU / 10,000 IU * 5 mL).
