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.

Explanation

To calculate the dose of methylprednisolone acetate injection, the nurse should use the following formula:

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

Correct Answer is ["10"]

Explanation

To give a patient cetirizine 5 mg PO, the nurse needs to measure the correct amount of liquid medicine. The medicine has a concentration of cetirizine 2.5 mg/5 mL, which means that every 5 mL of liquid contains 2.5 mg of cetirizine.

To find out how many mL of liquid are equivalent to 5 mg of cetirizine, the nurse can use a proportion:

2.5 mg / 5 mL = 5 mg / x mL

Cross-multiplying and solving for x, the nurse gets:

x = (5 mL x 5 mg) / 2.5 mg

x = 10 mL

Therefore, the nurse should administer 10 mL of liquid medicine to give the patient cetirizine 5 mg PO.
