Pharmacy Technician Certification Exam Practice Questions Practice Question
Given the following prescription: Lactulose 10 g/15 mL 15 mL PO t.i.d. for 10 days How many tablespoonfuls should be taken at each dose?
Correct Answer: A
Rationale: To convert milliliters to tablespoonfuls, it's important to know that 1 tablespoon is approximately 15 mL. The prescription indicates a dosage of 15 mL, which directly translates to 1 tablespoonful.
Option B (2 tablespoonfuls) is incorrect because it would imply a dosage of 30 mL, which exceeds the prescribed amount.
Option C (3 tablespoonfuls) suggests a dosage of 45 mL, again far beyond what is indicated.
Option D (4 tablespoonfuls) would equal 60 mL, which is not only excessive but also potentially harmful. Therefore, 1 tablespoonful accurately reflects the prescribed dosage of 15 mL.
