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 ["286"]
Explanation
To solve this problem, the nurse needs to convert the client's weight from pounds to kilograms, and then use the formula:
mL = (mg/kg x kg) / (mg/mL)
The client's weight in kilograms is:
126 lb / 2.2 lb/kg = 57.27 kg
The concentration of foscarnet in mg/mL is:
6,000 mg / 500 mL = 12 mg/mL
Plugging these values into the formula, we get:
mL = (60 mg/kg x 57.27 kg) / (12 mg/mL)
mL = (3,436.2 mg) / (12 mg/mL)
mL = 286.35 mL
Therefore, the nurse should administer 286 mL of foscarnet.
Correct Answer is ["6.5"]
Explanation
To answer this question, we need to perform some calculations. First, we need to convert the client's weight from pounds to kilograms. We can do this by dividing 143 by 2.2, which gives us 65 kg. Next, we need to multiply the dose of cyclosporine by the client's weight to get the total amount of medication needed. We can do this by multiplying 5 mg/kg by 65 kg, which gives us 325 mg. Finally, we need to divide the total amount of medication by the concentration of the injection to get the volume to administer. We can do this by dividing 325 mg by 50 mg/mL, which gives us 6.5 mL. Therefore, the nurse should administer 6.5 mL of cyclosporine injection to the client.
