A nurse is preparing to administer diphenhydramine 35 mg IM. Available is diphenhydramine injection 50 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.)

Answer and Explanation

The Correct Answer is ["0.7"]

To calculate the dosage of diphenhydramine injection, the nurse should use the formula D/H x Q, where D is the desired dose, H is the dose on hand, and Q is the quantity. In this case, D is 35 mg, H is 50 mg/mL, and Q is 1 mL.

Plugging these values into the formula, we get:

35 mg / 50 mg/mL x 1 mL = 0.7 mL

Therefore, the nurse should administer 0.7 mL of diphenhydramine injection.

Correct Answer is ["1.9"]

Explanation

To calculate the dosage of isoniazid injection, the nurse should use the formula D/H x Q, where D is the desired dose, H is the dose on hand, and Q is the quantity.

In this case, D is 187 mg, H is 100 mg/mL, and Q is 1 mL.

Plugging these values into the formula, we get:

187 mg / 100 mg/mL x 1 mL = 1.87 mL

To round the answer to the nearest tenth, the final answer is: 1.9 mL

The nurse should administer 1.9 mL of isoniazid injection to the patient.

Correct Answer is ["0.5"]

Explanation

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.
