ممرض يأخذ مسحة بلعومية أنفية لفحص فيروس تنفسي. أي طريقة صحيحة؟

A nurse takes a nasopharyngeal swab for a respiratory virus. Which technique is correct?

1. Angled upward toward the eye inside the nasal cavity
2. Horizontally along the nasal floor, then rotate
3. Insert it through the mouth to the tonsils
4. Swab only the front of the nostril

Answer: B) Horizontally along the nasal floor, then rotate. A nasopharyngeal swab follows the nasal floor horizontally to the nasopharynx and is rotated for a few seconds. Angling upward is wrong and painful. Staff wear appropriate PPE.
