Pharmacy Technician Certification Exam Practice Question
Which of the following is the best procedure for measuring liquid in a graduated cylinder?
Correct Answer: A
Rationale: Option A is the best procedure as it emphasizes placing the graduated cylinder on a level surface and reading the top of the meniscus at eye level, ensuring accurate measurement by minimizing parallax error.
Option B is incorrect because reading the bottom of the meniscus is not standard practice; the top of the meniscus should be used for accuracy.
Option C is misleading; while holding the cylinder at eye level is important, reading the top of the meniscus is essential for correct measurement.
Option D also misguides by suggesting reading the bottom of the meniscus, which can lead to inaccurate results.
