A nurse is preparing to administer hydrocortisone 150 mg via IV bolus. Available is hydrocortisone 50 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 ["3"]

To calculate the amount of hydrocortisone 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) = (150 mg / 50 mg/mL)

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

Amount to administer (mL) = (150 / 50) = 3 mL

So, the nurse should administer 3 mL of hydrocortisone via IV bolus.

Correct Answer is ["4.5"]

Explanation

To calculate the dose of ondansetron that the nurse should administer, we can follow these steps:

Convert the client's weight from pounds to kilograms:

132 lb ÷ 2.2 = 60 kg

Calculate the dose of ondansetron:

0.15 mg/kg × 60 kg = 9 mg

Determine the volume of ondansetron needed using the available concentration:

9 mg ÷ 2 mg/mL = 4.5 mL

Rounding to the nearest tenth, the nurse should administer 4.5 mL of ondansetron via IV.

Correct Answer is ["750"]

Explanation

To calculate the infusion rate for the first 8 hours, we can use the following formula:

Infusion rate (mL/hr) = (Volume to be infused / Time for infusion)

First, we need to find the volume to be infused in the first 8 hours:

Volume for the first 8 hours = Total volume / 2 = 12 L / 2 = 6 L = 6000 mL

Now we can calculate the infusion rate for the first 8 hours:

Infusion rate = 6000 mL / 8 hr = 750 mL/hr

Therefore, the nurse should set the IV pump to deliver 750 mL/hr during the first 8 hours.
