Correct Answer is ["2"]
Explanation
Volume (mL) = Dose (mcg) / Concentration (mcg/mL) Volume (mL) = 100 mcg / 50 mcg/mL
Volume (mL) = 2 mL
Therefore, the nurse should administer 2 mL of fentanyl injection 0.05 mg/mL to the client
Correct Answer is ["0.6"]
Explanation
Step 1: Determine the amount of enoxaparin in mg per mL. 60 mg ÷ 0.6 mL = 100 mg/mL
Result: 100 mg/mL
Step 2: Calculate the volume in mL needed to administer 55 mg. 55 mg ÷ 100 mg/mL = 0.55 mL
Result: 0.55 mL
Step 3: Round the result to the nearest tenth. 0.55 mL rounded to the nearest tenth = 0.6 mL
Result: 0.6 mL
The nurse should administer 0.6 mL of enoxaparin.
