A nurse is preparing to administer morphine 7.5 mg subcutaneously.
The available morphine is an injection of 10 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest hundredth.
Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.75"]
Step 1: Divide the ordered dose by the available strength: 7.5 mg ÷ 10 mg/mL = 0.75 mL So, the nurse should administer 0.75 mL.

Correct Answer is ["68"]
Explanation
Step 1 is convert the client's weight from pounds to kilograms. 99 lb ÷ 2.2 = 45 kg
Step 2 is calculate the required dose of acetaminophen in mg. 15 mg/kg × 45 kg = 675 mg
Step 3 is calculate the volume of acetaminophen solution required to administer 675 mg. 675 mg ÷ (1,000 mg ÷ 100 mL) = 67.5 mL
Rounded to the nearest whole number, the nurse should administer 68 mL of acetaminophen.
Correct Answer is ["104"]
Explanation
Step 1: Convert the total volume to mL: 2.5 L = 2500 mL Step 2: Divide the total volume by the total time: 2500 mL ÷ 24 hr = 104.17 mL/hr Step 3: Round to the nearest whole number: 104 mL/hr So, the nurse should administer 104 mL/hr.
