A nurse is preparing to administer benztropine 2 mg IM every 12 hr to a client who is experiencing an extrapyramidal reaction. Available is benztropine 1 mg/mL for injection. How many ml should the nurse administer per dose? (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 ["2"]

The nurse is preparing to administer benztropine 2 mg IM every 12 hours. The concentration of the available benztropine is 1 mg/mL.

To calculate the volume (mL) of the medication needed for the prescribed dose, you can use the formula:

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

Plugging in the values:

Volume (mL) = 2 mg / 1 mg/mL = 2 mL

So, the nurse should administer 2 mL of benztropine 1 mg/mL for each dose. Since we're looking for a whole number, we round to the nearest whole number, which is 2 mL.

Correct Answer is ["0.75"]

Explanation

To calculate the volume (ml) of haloperidol decanoate needed for a dose of 75 mg, you can use the following formula:

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

Given:

Dose = 75 mg

Concentration = 100 mg/ml

Plugging in the values:

Volume (ml) = 75 mg / 100 mg/ml

Volume (ml) = 0.75 ml

Rounding to the nearest hundredth:

Volume (ml) = 0.75 ml

So, the nurse should administer 0.75 ml of haloperidol decanoate for the dose of 75 mg.
