A client who weighs 176 pounds receives a prescription for lorazepam 0.05 mg/kg intramuscularly 2 hours before a scheduled procedure. The medication is available in 4 mg/mL vial. How many mL should the nurse administer? (Enter numeric value only.)
The Correct Answer is ["1 mL"]
The correct answer is 1 mL. To find the answer, we can use the following steps:
- Convert the client's weight from pounds to kilograms by dividing by 2.2
- Multiply the weight in kilograms by the dosage in mg/kg
- Divide the dose in mg by the concentration in mg/mL
- Round the result to the nearest whole number
Using these steps, we get:
- (weight in kg) = (176) / (2.2) = 80 kg
- (dose in mg) = (0.05) x (80) = 4 mg
- (volume in mL) = (4) / (4) = 1 mL
- (rounded volume in mL) = 1 mL
Therefore, the nurse should administer 1 mL of lorazepam from the vial to the client.

Correct Answer is ["400 mL\/hour"]
Explanation
To find the answer, we can use the following formula:
(mL/hour) = (mL/minute) x 60
Substituting the given values, we get:
(mL/hour) = (1000 / 150) x 60
Simplifying, we get:
(mL/hour) = 6.667 x 60
(mL/hour) = 400
Therefore, the nurse should program the infusion pump to deliver 400 mL/hour of 0.9% Sodium chloride Injection, USP to the patient.
Correct Answer is ["0.5"]
Explanation
The correct answer is 0.5 mL. To find the answer, we can use the following formula:
(mL to be administered) = (mg prescribed) / (mg per mL)
Substituting the given values, we get:
(mL to be administered) = (200) / (1000 / 2.5)
Simplifying, we get:
(mL to be administered) = (200) x (2.5 / 1000)
(mL to be administered) = 0.5
Therefore, the nurse should administer 0.5 mL of streptomycin from the vial to the client.
