A nurse is preparing to administer 0.9% sodium chloride 1,200 ml. IV to infuse over 8 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.)
The Correct Answer is ["150"]
To calculate the IV pump rate, you need to divide the total volume (1,200 ml) by the total infusion time (8 hours). Here's the calculation:
IV Pump Rate (ml/hr) = Total Volume (ml) / Total Infusion Time (hr)
IV Pump Rate (ml/hr) = 1,200 ml / 8 hr
IV Pump Rate (ml/hr) = 150 ml/hr
So, the nurse should set the IV pump to deliver 150 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 ["2.3"]
Explanation
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.
