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

Correct Answer is ["2"]
Explanation
Given:
Desired dose of acetaminophen: 0.65 g
Concentration of acetaminophen tablets: 325 mg/tablet
Conversion factor: 1 g = 1,000 mg
Step 1: Convert the desired dose to milligrams:
Desired dose in mg = Desired dose in g x 1,000 mg/g
Desired dose in mg = 0.65 g x 1,000 mg/g
Desired dose in mg = 650 mg
Step 2: Calculate the number of tablets:
Number of tablets = Desired dose in mg / Concentration per tablet (mg/tablet)
Number of tablets = 650 mg / 325 mg/tablet
Number of tablets = 2 tablets
