A nurse is preparing to administer fentanyl 50 mcg IM to a client. Available is fentanyl 0.05 mg/mL. How many ml should the nurse administer per dose?
(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["1"]
To answer this question, you need to convert the dosage of fentanyl from micrograms (mcg) to milligrams (mg). One milligram is equal to 1000 micrograms, so 50 mcg is equal to 0.05 mg. Then, you need to use the formula D/H x Q, where D is the desired dose, H is the dose on hand, and Q is the quantity. In this case, D is 0.05 mg, H is 0.05 mg/mL, and Q is the volume in milliliters. Plugging these values into the formula, you get:
0.05 mg / 0.05 mg/mL x Q
Q = 1 mL
Therefore, the nurse should administer 1 mL of fentanyl per dose.

Correct Answer is ["100"]
Explanation
To calculate the IV pump rate in mL/hr, you need to divide the volume of the solution in mL by the infusion time in hr. In this case, the formula is 100 mL / 1 hr = 100 mL/hr.
Therefore, the nurse should set the IV pump to deliver 100 mL/hr of metronidazole.
Correct Answer is ["20"]
Explanation
To calculate the volume of medication to administer, use the formula: (desired dose / available dose) x available volume. Plug in the values: (25 mg / 6.25 mg) x 5 mL = 20 mL. Round to the nearest whole number: 20 mL.
