A nurse is preparing to administer morphine 7.5 mg subcutaneous. Available is morphine injection 10 mg/mL. How many mL should the nurse administer?
(Round the answer to the nearest hundredth. Use a leading zero if it applies. Do not use a trailing zero.)
Answer and Explanation

The Correct Answer is ["0.75"]

To calculate the volume of morphine injection that the nurse should administer, we can use the following steps:

Determine the volume to be administered:

   We have a concentration of 10 mg/mL.

   7.5 mg ÷ 10 mg/mL = 0.75 mL

Therefore, the nurse should administer 0.75 mL of morphine injection subcutaneously.

Correct Answer is ["150"]

Explanation

To calculate the IV pump rate for the 0.9% sodium chloride 1,200 mL IV to infuse over 8 hours, we can use the following formula:

IV pump rate (mL/hr) = Total volume (mL) / Time (hr)

Using the given values:

Total volume = 1,200 mL

Time = 8 hours

Plugging these values into the formula:

IV pump rate = 1,200 mL / 8 hr

IV pump rate = 150 mL/hr

So, the nurse should set the IV pump to deliver 150 mL/hr to infuse the 1,200 mL of 0.9% sodium chloride over 8 hours.

Correct Answer is ["69"]

Explanation

To calculate the amount of voriconazole to be administered, we can follow these steps:

Convert the client's weight from pounds to kilograms.

Calculate the total amount of voriconazole needed based on the client's weight.

Determine the volume of the medication to be administered based on the concentration of the available solution.

Let's proceed with the calculations:

Converting the client's weight from pounds to kilograms:

Client's weight = 127 lb

1 lb ≈ 0.453592 kg

Client's weight ≈ 127 lb 0.453592 kg/lb ≈ 57.61 kg

Calculating the total amount of voriconazole needed:

Voriconazole dose = 6 mg/kg 57.61 kg ≈ 345.66 mg

Determining the volume of the medication to be administered:

Available voriconazole concentration = 5 mg/mL

Volume to be administered = 345.66 mg / 5 mg/mL ≈ 69.132 mL

Rounding to the nearest whole number, the nurse should administer 69 mL of voriconazole.
