A nurse is preparing to administer morphine 0.1 mg/kg IM to a client who weighs 99 lb. Available is morphine 2 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 ["2.3"]

To calculate the amount of morphine (in mL) the nurse should administer, follow these steps:

Step 1: Convert the client's weight from pounds to kilograms. 99 lb / 2.2 lb/kg ≈ 45 kg (rounded to the nearest whole number)

Step 2: Calculate the total dose based on the client's weight. 0.1 mg/kg * 45 kg = 4.5 mg

Step 3: Determine how many mL of the available morphine solution (2 mg/mL) are needed to achieve the prescribed dose. 4.5 mg ÷ 2 mg/mL = 2.25 mL

Rounded to the nearest tenth, the nurse should administer 2.3 mL of morphine.

Correct Answer is ["48"]

Explanation

To calculate how many milliliters (ml) of gentamicin to administer, follow these steps:
Calculate the client's weight in kilograms: Weight in kilograms = Weight in pounds / 2.2
Weight in kilograms = 210 lb / 2.2 Weight in kilograms ≈ 95.45 kg

Determine the dose based on the weight: Dose = 5 mg/kg × Weight in kilograms Dose = 5 mg/kg × 95.45 kg Dose ≈ 477.25 mg

Check the concentration of the available gentamicin: Concentration = 10 mg/mL

Calculate the volume (ml) to administer: Volume (ml) = Dose (mg) / Concentration (mg/ml) Volume (ml) = 477.25 mg / 10 mg/ml Volume (ml) ≈ 47.73 ml

Rounded to the nearest whole number, the nurse should administer approximately 48 ml of gentamicin.

Correct Answer is ["2.4"]

Explanation

To calculate the amount of calcitonin the nurse should administer, follow these steps:

Calculate the client's weight in kilograms: Weight in kilograms = Weight in pounds / 2.2 Weight in kilograms = 130 lb / 2.2 = 59.09 kg (rounded to two decimal places)

Calculate the total units of calcitonin needed: Total units = Weight in kilograms × Dose per kilogram Total units = 59.09 kg × 8 units/kg = 472.72 units

Determine the volume (ml) to administer using the concentration of the available calcitonin: Volume (ml) = Total units needed / Concentration (units/ml) Volume (ml) = 472.72 units / 200 units/ml = 2.36 ml

Rounded to the nearest tenth of a milliliter, the nurse should administer 2.4 ml of calcitonin.
