A nurse is preparing to administer acetaminophen 40 mg po q 8 hr PRN pain. Available is acetaminophen oral solution 10 mg/2.5 mL. How many teaspoons (tsp) should the nurse administer per dose?______tsp (Round the answer to the nearest whole number. Use a leading, zero if it applies. Do not use a trailing zero)
Correct Answer: 2 tsp
Rationale: To calculate the amount of acetaminophen solution to administer, we first need to determine the total amount of medication needed per dose. The prescription is for 40 mg, and the concentration of the oral solution is 10 mg/2.5 mL.
Step 1: Calculate how many mL are needed per dose:
40 mg ÷ 10 mg/2.5 mL = 40 mg ÷ 4 mg/mL = 10 mL
Step 2: Convert 10 mL to teaspoons:
1 teaspoon (tsp) = 5 mL
Therefore, 10 mL ÷ 5 mL/tsp = 2 tsp
So, the correct answer is 2 tsp.
Other choices are incorrect because they do not accurately reflect the calculated dose based on the prescription and the concentration of the oral solution.
