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 medication is available in a 2 mg/mL vial. How many mL should the nurse administer?
(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).

Correct Answer is ["18"]
Explanation
The client is to receive furosemide 60 mg every 12 hours.
The drug is available in a concentration of 10 mg/mL, so the nurse should administer 6 mL of medication (60 mg / 10 mg/mL).
The nurse plans to administer the dosage over 20 minutes, so the infusion rate should be 18 mL/hour (6 mL / (20 minutes / 60 minutes/hour)).
Correct Answer is ["0.25"]
Explanation
The child weighs 55 pounds which is equivalent to 24.95 kg (1 kg = 2.20462 pounds).
The healthcare provider prescribes epinephrine 0.01 mg/kg, so the child should receive 0.2495 mg of epinephrine (0.01 mg/kg 24.95 kg).
The available medication is labeled 1 mg/mL, so the nurse should administer 0.25 mL of medication (0.2495 mg / 1 mg/mL).
