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.)
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 ["167"]
Explanation
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 ["125"]
Explanation
To calculate the infusion rate in mL/hr, you can use the following formula:
Infusion Rate (mL/hr) = Total Volume (mL) / Time (hr)
In this case, the total volume is 1,500 mL, and the time is 12 hours:
Infusion Rate (mL/hr) = 1,500 mL / 12 hr = 125 mL/hr
So, the nurse should set the IV pump to deliver 125 mL/hr.
