Question 1 of 34 :
A nurse is preparing to administer acetaminophen 56 mg PO to a newborn. Available is acetaminophen oral solution 160 mg/5 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.)
Correct Answer: 1.8
Formula:
Dose to administer (mL) = (Ordered dose (mg) / Available dose (mg)) × Available volume (mL)
Given:
Ordered dose: 56 mg
Available dose: 160 mg/5 mL
Volume (mL) = (56 mg / 160 mg) × 5 mL
= 0.35 × 5 mL
= 1.75 mL
Rounded to the nearest tenth: 1.8 mL.
The nurse will administer 1.8 mL of acetaminophen.
