Question 1 of 5
A nurse is preparing to administer amoxicillin 350 mg PO. Available is amoxicillin 250 mg/5 mL. How many mL should the nurse administer?
Correct Answer: B
Rationale: The correct answer is B.
To determine the mL to administer, you need to set up a proportion: 250 mg is to 5 mL as 350 mg is to x mL. Cross multiply: 250x = 350*5. Solve for x: x = (350*5) / 250 = 7 mL.
Choice A is incorrect because it does not account for the correct calculation based on the proportion.
Choices C to G are incorrect as they are not calculated using the correct ratio of mg to mL.
