Which nasal spray administration step is correct?

• A. Spray while inhaling deeply
• B. Hold breath while spraying
• C. Spray into the center of the nostril
• D. Inhale and exhale while spraying

Answer: (A)

Coordinating the spray with inhalation is essential for effective nasal medication delivery. When the spray is released as the patient inhales, the mist travels into the nasal passages and coats the nasal mucosa, where absorption occurs. If the spray is administered while the patient holds their breath, the medication tends to stay in the front part of the nostril and may not reach the mucosa. If they exhale during spraying, the mist can be pushed back out or toward the throat, reducing local deposition. Aiming the spray toward the center of the nostril isn’t ideal because it can irritate the nasal septum and doesn’t optimize distribution to the mucosa; directing it toward the outer wall while the patient inhales helps the medicine coat the intended surfaces more effectively.
