A nurse is preparing to administer filgrastim 480 mcg subcutaneous daily. Available is filgrastim injection 300 mcg/mL. How many mL should the nurse administer per dose? (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 ["1.6"]

To calculate the dose of filgrastim, the nurse should use the following formula:

Dose (mL) = Ordered dose (mcg) / Available dose (mcg/mL)

Plugging in the values from the question, we get:

Dose (mL) = 480 mcg / 300 mcg/mL

Dose (mL) = 1.6 mL

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 ["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.
