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"]
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 ["240"]
Explanation
To find the answer, we can use the following steps:
- Calculate the amount of water needed to dilute the formula to 75% by subtracting the volume of the prescribed solution from the volume of the full strength formula
- Subtract the amount of water from the volume of the can to get the amount of enteral nutrition formula
- Round the result to the nearest whole number
Using these steps, we get:
- (water in mL) = (320) - (240) = 80 mL
- (enteral nutrition formula in mL) = (240) - (80) = 160 mL
- (rounded enteral nutrition formula in mL) = 160 mL
Therefore, the nurse should use 160 mL of enteral nutrition formula from the can to prepare the solution.
Correct Answer is ["1.2"]
Explanation
To find the answer, we can use the following steps:
- Convert the client's weight from pounds to kilograms by dividing by 2.2
- Calculate the dose of enoxaparin in mg per administration by multiplying the weight in kg by the dosage in mg/kg
- Divide the dose in mg per administration by the concentration of enoxaparin in the prefilled syringe in mg/mL
- Multiply the volume in mL per administration by the number of administrations per day
- Round the result to the nearest tenth
Using these steps, we get:
- (weight in kg) = (132) / (2.2) = 60 kg
- (dose in mg per administration) = (1) x (60) = 60 mg
- (volume in mL per administration) = (60) / (60 / 0.6) = 0.6 mL
- (volume in mL per day) = (0.6) x (2) = 1.2 mL
- (rounded volume in mL per day) = 1.2 mL
Therefore, the nurse should administer 1.2 mL of enoxaparin per day.
