Answer and Explanation

The Correct Answer is ["30"]

Correct Answer is ["0.7"]

Explanation

To calculate the dosage of morphine for a child, the nurse needs to convert the child's weight from pounds to kilograms and then multiply it by the prescribed dose per kilogram. The nurse also needs to divide the resulting amount by the concentration of the morphine injection to get the volume to be administered. The formula is:

Volume (mL) = (Weight (kg) x Dose (mg/kg)) / Concentration (mg/mL)

In this case, the child weighs 77 lb, which is equivalent to 35 kg (77 / 2.2 = 35). The prescribed dose is 0.2 mg/kg and the concentration of the morphine injection is 10 mg/mL. Therefore, the volume to be administered is:

Volume (mL) = (35 x 0.2) / 10

Volume (mL) = 0.7

The nurse should round the answer to the nearest tenth, which is 0.7 mL.

Correct Answer is ["2"]

Explanation

To calculate the number of capsules needed to administer 0.5 g of cefaclor PO, the nurse should use the following formula:

Number of capsules = (Desired dose / Available dose) x 1 capsule

Plugging in the values from the question, we get:

Number of capsules = (0.5 g / 0.25 g) x 1 capsule

Number of capsules = 2 capsules

Therefore, the nurse should plan to administer 2 capsules of cefaclor PO to the client.
