Certified Clinical Medical Assistant Exam Practice Question

Correct Answer: B

Rationale: Instructing the patient to pinch their nose (Option B) is the most effective immediate action to control a nosebleed. This technique helps apply pressure to the bleeding site, promoting clot formation and reducing blood flow.

Tilting the head back (Option A) can lead to blood flowing down the throat, increasing the risk of swallowing blood or choking. Applying an ice pack to the back of the neck (Option C) has minimal effect on nasal bleeding and is not a recommended first aid measure. Advising the patient to gently blow their nose (Option D) can worsen the bleeding by dislodging clots and increasing pressure in the nasal passages.
