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.

Explanation
First, we need to find out how many mg of warfarin are in one vial. Since the vial is labeled 5 mg/single-use, we can assume that it contains 5 mg of warfarin.
Next, we need to find out how many mL of solution are in one vial. Since the instructions say to reconstitute with 2.7 mL of sterile water for injection to yield 2 mg/mL, we can use the following formula:
Amount of solution= amount of water + amount of warfarin
Substituting the given values, we get:
Amount of solution = 2.7 + 5 =7.7 mL
Now, we need to find out how many mL of solution contain 2 mg of warfarin, which is the prescribed dose for the patient. We can use the following formula:
mL of solution = mg of warfarin/ concentration of warfarin
Substituting the given values, we get:
mL of solution = 2/2 = 1 mL
Therefore, the nurse should administer 1 mL of solution to the patient.
Correct Answer is ["100"]
Explanation
The correct answer is 100 mL/hour. To find the answer, we can use the following formula:
(mL/hour) = (mL/minute) x 60
Substituting the given values, we get:
(mL/hour) = (150 / 90) x 60
Simplifying, we get:
(mL/hour) = 1.667 x 60
(mL/hour) = 100
Therefore, the nurse should program the infusion pump to deliver 100 mL/hour of ganciclovir in IV bag.
