A nurse is preparing to administer chlorpromazine 12.5 mg IM to a client. Available is chlorpromazine 25 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.5"]
To calculate the dosage of chlorpromazine for a client, the nurse needs to use the formula D/H x V, where D is the desired dose, H is the dose on hand, and V is the volume on hand.
In this case, D is 12.5 mg, H is 25 mg, and V is 1 mL. Plugging these values into the formula, we get:
12.5 mg / 25 mg x 1 mL = 0.5 mL
The nurse should administer 0.5 mL of chlorpromazine to the client.

Explanation
To calculate the correct dosage of levothyroxine, the nurse should follow these steps:
- Convert the patient's weight from pounds to kilograms: 220 lb ÷ 2.20462 lb/kg = 99.79 kg
- Calculate the total dose of levothyroxine: 5 mcg/kg × 99.79 kg = 498.95 mcg
- Determine the number of tablets to administer: 498.95 mcg ÷ 75 mcg/tablet = 6.65 tablets
Therefore, the nurse should administer 7 tablets of levothyroxine.

Dose (mL) = Desired dose (mg) / Available dose (mg/mL)
Plugging in the values from the question, we get:
Dose (mL) = 60 mg / 80 mg/mL
Dose (mL) = 0.75 mL
