NHA Certified Phlebotomy Technician (CPT)Safety and ComplianceMedium
A phlebotomy technician is collecting blood from an adult patient who is known to have a history of fainting during blood draws. Which of the following is the most appropriate safety measure to implement before starting the procedure?
- APosition the patient in a supine or semi-Fowler's position.
- BHave the patient stand upright to promote better blood flow.
- CAdminister smelling salts to the patient as a preventative measure.
- DInstruct the patient to hold their breath during the draw.
Show answer & explanationAnswer & explanation
Correct answer: A. Position the patient in a supine or semi-Fowler's position.
For patients with a history of fainting (vasovagal syncope), positioning them supine (lying flat) or in a semi-Fowler's position (reclined with head slightly elevated) helps prevent or mitigate fainting by ensuring adequate blood flow to the brain and providing a safe position should they lose consciousness.
Why the other options are wrong
- B. This is incorrect; standing increases the risk of fainting and injury if they fall.
- C. This is inappropriate as a preventative measure and can be startling or irritating; smelling salts are typically used to revive someone who has already fainted.
- D. This is incorrect; holding breath can increase intrathoracic pressure and potentially worsen a vasovagal response.
Preventing Vasovagal Syncope
Measures taken to prevent or manage fainting episodes (vasovagal syncope) during blood collection, often triggered by anxiety, pain, or sight of blood.
- Positioning the patient supine or semi-Fowler's is key.
- Verbal reassurance and distraction can help.
- Monitor patient closely throughout the procedure.
