A patient receives a prescription for hydrocortisone sodium succinate 150 mg intravenously STAT. The powdered medication needs to be reconstituted with 2 mL of bacteriostatic water that will provide a solution of 250 mg/mL. How many mL should the nurse administer? (Enter numerical value only.)
The Correct Answer is ["0.6 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) = (150) / (250)
Simplifying, we get:
(mL to be administered) = 0.6
Therefore, the nurse should administer 0.6 mL of hydrocortisone sodium succinate to the patient.

Correct Answer is ["1 mL"]
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 ["75"]
Explanation
To find the answer, we can use the following steps:
- Calculate the dose of diphenhydramine in mg per administration by multiplying the volume in mL by the concentration in mg/mL
- Multiply the dose in mg per administration by the number of administrations per day
- Round the result to the nearest whole number
Using these steps, we get:
- (dose in mg per administration) = (15) x (12.5 / 5) = 37.5 mg
- (total daily dose in mg) = (37.5) x (2) = 75 mg
- (rounded total daily dose in mg) = 75 mg
Therefore, the client receives 75 mg of diphenhydramine per day.
