Question 1 of 5
A nurse is preparing to administer amoxicillin 250 mg PO. Available is amoxicillin oral suspension 125 mg/5 mL. How many mL should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.).
Correct Answer: D
Rationale:
To determine the correct amount of oral suspension to administer, we first need to calculate the total mL needed for 250 mg of amoxicillin. Given that the concentration is 125 mg/5 mL, we can set up a proportion: 125 mg is to 5 mL as 250 mg is to x mL. Cross multiply to find x: 125x = 250*5. Solving for x, we get x = 250*5/125 = 10 mL.
Therefore, the nurse should administer 10 mL of amoxicillin oral suspension.
Choice A (2 mL) is incorrect because it is only half of the calculated amount.
Choice B (5 mL) is incorrect because it does not account for the higher dosage required.
Choice C (8 mL) is incorrect as it is too low based on the calculation.
