The healthcare provider prescribes cefazolin 800 mg IM every six hours. The available vial is labeled, "Cefazolin 1 gram," and the instructions for reconstitution state, "For IM use add 2.5 mL sterile water for injection to provide a total volume of 3.0 mL." After reconstitution, the solution contains how many mg/mL? (Enter numeric value only. If rounding is required, round to the nearest whole number.)
The Correct Answer is ["333"]
To find the answer, we can use the following formula:
(mg/mL) = (mg of cefazolin) / (mL of solution)
Substituting the given values, we get:
(mg/mL) = (1000) / (3)
Simplifying, we get:
(mg/mL) = 333.333
(rounded mg/mL) = 333
Therefore, after reconstitution, the solution contains 333 mg/mL of cefazolin.

Correct Answer is ["0.4 mL"]
Explanation
To find the answer, we can use the following formula:
(mL to be administered) = (units prescribed) / (units per mL)
Substituting the given values, we get:
(mL to be administered) = (240,000) / (1,200,000 / 2)
Simplifying, we get:
(mL to be administered) = (240,000 x 2) / (1,200,000)
(mL to be administered) = 480,000 / 1,200,000
(mL to be administered) = 0.4
Therefore, the nurse should administer 0.4 mL of penicillin G procaine to the child.
Correct Answer is ["100 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) = (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.
