Certified Medical Assistant (CMA AAMA)Procedures, Examinations and DiagnosticsEasy
A medical assistant is preparing to perform a routine venipuncture on an adult patient who has no contraindications. Which position should the patient be placed in to minimize the risk of injury from fainting during the procedure?
- AFowler's position with the head elevated 90 degrees
- BSitting in a chair with an armrest, or lying in a supine position
- CTrendelenburg position with the head lower than the feet
- DStanding position with arm extended on a table
Show answer & explanationAnswer & explanation
Correct answer: B. Sitting in a chair with an armrest, or lying in a supine position
Patients undergoing venipuncture should be seated in a chair with a supportive armrest or lying supine to reduce the risk of injury if they faint (vasovagal syncope) during or after the procedure. Standing increases fall risk, and Fowler's or Trendelenburg positions are not standard for routine blood draws.
Why the other options are wrong
- A. Fowler's position is used for respiratory or upper body exams, not standard venipuncture.
- C. Trendelenburg is reserved for shock treatment, not routine blood draws.
- D. Standing increases the risk of falling and injury if the patient faints.
Venipuncture Patient Positioning
Patients should be seated with a supportive armrest or lying supine during venipuncture to minimize injury risk if they experience vasovagal syncope (fainting).
- Armrest prevents falls if patient faints
- Supine position is an alternative for high fall-risk patients
- Standing is avoided due to injury risk
Memory trick: 'Sit supported or lie flat, don't stand where you might fall flat'
