A nurse is preparing to administer promethazine 25 mg IM to a client. Available is promethazine 50 mg/ml. How many ml administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero)

Answer and Explanation

The Correct Answer is ["0.5"]

To calculate the volume (mL) needed to administer 25 mg of promethazine using a concentration of 50 mg/mL, you can use the following formula:

Volume (mL) = Dose (mg) / Concentration (mg/mL)

In this case, the dose is 25 mg, and the concentration is 50 mg/mL:

Volume (mL) = 25 mg / 50 mg/mL = 0.5 mL

So, the nurse should administer 0.5 mL of promethazine.

Correct Answer is ["0.5"]

Explanation

To calculate how many tablets of lisinopril 5 mg the nurse should administer to achieve a 2.5 mg dose, divide the desired dose by the dose per tablet:

Number of tablets = Desired dose / Dose per tablet

Number of tablets = 2.5 mg / 5 mg/tablet

Number of tablets = 0.5 tablets

Correct Answer is ["20.3"]

Explanation

To calculate the amount of acetaminophen liquid to administer, you can use the following formula:

Amount (mL) = (Desired Dose in mg) / (Concentration in mg/mL)

Amount (mL) = 650 mg / (160 mg/5 mL) = 20.31 mL

Rounded to the nearest tenth, the nurse should administer approximately 20.3 mL of acetaminophen liquid.
