A nurse is preparing to administer dextrose 5% in water 1,000 mL IV to infuse over 6 hr. The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["167"]

To calculate the infusion rate in mL/hr for dextrose 5% in water 1,000 mL over 6 hours, you can use the following formula:

Infusion Rate (mL/hr) = Total Volume (mL) / Total Time (hr)

Infusion Rate = 1,000 mL / 6 hr ≈ 166.67 mL/hr

Rounded to the nearest whole number, the nurse should set the IV pump to deliver approximately 167 mL/hr.

Correct Answer is ["0.5"]

Explanation

To calculate the volume (mL) needed to administer 25 mg of promethazine using a concentration of 50 mg/mL, you can use the following formula:

Volume (mL) = Dose (mg) / Concentration (mg/mL)

In this case, the dose is 25 mg, and the concentration is 50 mg/mL:

Volume (mL) = 25 mg / 50 mg/mL = 0.5 mL

So, the nurse should administer 0.5 mL of promethazine.

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.
