A nurse is preparing to administer morphine 0.2 mg/kg IM to a child who weighs 77 lb. Available is morphine injection 10 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 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 ["1.1"]

Explanation

To calculate the dosage of cefazolin, 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 250 mg, H is 225 mg/mL, and Q is 1 mL.

Plugging these values into the formula, we get:

250 mg / 225 mg/mL x 1 mL = 1.11 mL

Therefore, the nurse should administer 1.1 mL of cefazolin IM to the client.

Correct Answer is ["3"]

Explanation

To calculate the number of tablets that the nurse should administer per dose, the nurse needs to convert the prescribed dose of calcium carbonate from grams to milligrams and then divide it by the strength of the available tablets. The formula is:

Prescribed dose (mg) / Tablet strength (mg) = Number of tablets

The prescribed dose of calcium carbonate is 3.9 g PO daily in equally divided doses every 12 hr.

To convert grams to milligrams, multiply by 1000.

Therefore, 3.9 g = 3900 mg.

Since the doses are equally divided every 12 hr, the nurse needs to divide the daily dose by 2 to get the dose per 12 hr. Therefore, 3900 mg / 2 = 1950 mg.

The available tablets have a strength of 650 mg each.

To find the number of tablets per dose, divide the dose per 12 hr by the tablet strength.

Therefore, 1950 mg / 650 mg = 3 tablets.
