Answer and Explanation

The Correct Answer is ["8"]

To calculate the dose of phenytoin oral suspension, the nurse should use the following formula:

Dose (mL) = Desired dose (mg) / Concentration (mg/mL) x Volume (mL)

Plugging in the values from the question, we get:

Dose (mL) = 200 mg / 125 mg/5 mL x 5 mL

Simplifying the equation, we get:

Dose (mL) = 8 mL

Correct Answer is ["2"]

Explanation

To calculate the dosage of diazepam, the nurse needs to 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 10 mg, H is 5 mg/mL, and Q is 1 mL.

Plugging these values into the formula, we get:

10 mg / 5 mg/mL x 1 mL = 2 mL

Therefore, the nurse should administer 2 mL of diazepam injection to the client.
