Can an EMT repeat an intranasal dose after 1 mL per nare?

• A. EMT may not repeat intranasal dose after 1 mL per nare
• B. EMT may repeat intranasal dose any number of times
• C. EMT may repeat intranasal dose after 0.5 mL per nare
• D. EMT may repeat only if physician authorizes

Answer: (A)

Intranasal dosing uses a very small, per-nostril volume because the nasal mucosa absorbs medication effectively only up to a certain amount. The spray device is designed to deliver about 1 mL into each nostril, and pushing more into the same nostril doesn’t improve absorption and can cause irritation, dripping, or aspiration. Because of this absorption limit, the protocol does not allow repeating an intranasal dose after 1 mL per nare has been given. If more medication is needed, higher-level guidance or a different administration route would be pursued rather than repeating intranasal dosing after the limit is reached.
