A nurse is preparing to administer morphine 8mg IM to a client who is postpartum. Available is morphine injection 10 mg/mL. How many mL should the nurse plan to administer? (Round the answer to the nearest tenth. Use leading zero if it applies.)
The Correct Answer is ["0.8"]
Step 1: Set up the proportion:
Desired dose (mg) / Volume to administer (mL) = Concentration (mg/mL)
Step 2: Substitute the values:
8 mg / Volume = 10 mg/mL
Step 3: Solve for the unknown volume:
Volume = 8 mg / 10 mg/mL
Step 4: Calculate the volume:
Volume = 0.8 mL

Explanation
Given:
Total volume to be infused: 1,500 mL
Infusion time: 8 hours
Step 1: Calculate the infusion rate:
Infusion rate (mL/hr) = Total volume (mL) / Infusion time (hr)
Step 2: Substitute the values:
Infusion rate (mL/hr) = 1,500 mL / 8 hr
Step 3: Calculate the infusion rate:
Infusion rate (mL/hr) = 187.5 mL/hr
Step 4: Round to the nearest whole number:
Infusion rate (mL/hr) ≈ 188 mL/hr
Correct Answer is ["80"]
Explanation
Given:
Total volume to be infused: 800 mL
Infusion time: 10 hours
Step 1: Calculate the infusion rate:
Infusion rate (mL/hr) = Total volume (mL) / Infusion time (hr)
Step 2: Substitute the values:
Infusion rate (mL/hr) = 800 mL / 10 hr
Step 3: Calculate the infusion rate:
Infusion rate (mL/hr) = 80 mL/hr
