A nurse is preparing to administer voriconazole 6 mg/kg via intermittent IV bolus to a client who weighs 127 lb. Available is voriconazole 5 mg/mL. How many mL should the nurse administer?
(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Answer and Explanation

The Correct Answer is ["69"]

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.

Correct Answer is ["0.71"]

Explanation

To calculate how many milliliters (mL) of the reconstituted medication the nurse should administer, we can use the following formula:

Desired dose (in mg) / Stock concentration (in mg/mL) = Volume to administer (in mL)

Given information:

Desired dose of ceftriaxone: 250 mg

Stock concentration after reconstitution: 350 mg/mL

Now let's calculate the volume to administer:

250 mg / 350 mg/mL = 0.7143 mL

Rounding to the nearest hundredth, the nurse should administer 0.71 mL of the reconstituted medication.

Correct Answer is ["8"]

Explanation

To calculate the amount of phenytoin oral suspension to administer, we can use the following formula:

Amount to administer (mL) = (Desired dose (mg) / Available dose (mg/mL))

Plugging in the given values:

Amount to administer (mL) = (200 mg / 125 mg/5 mL)

Now, let's solve for the amount to administer:

Amount to administer (mL) = (200 mg / 125 mg/5 mL) = (200 / 125) 5 = 8

So, the nurse should administer 8 mL of phenytoin oral suspension via the gastrostomy tube.
