What is the maximum depth to insert nasal drops into the nostril?

The correct choice is based on the recommended depth for inserting nasal drops, which is approximately 3/8 inch into the nostril. This depth is considered optimal to ensure the medication is effectively delivered into the nasal passage, where absorption can occur, while also minimizing the risk of discomfort or injury to delicate nasal tissues. This guideline is established by safety and efficacy considerations in order to achieve the desired therapeutic effects without causing harm.

Inserting nasal drops too shallow may result in the medication running out and not being absorbed effectively, while going too deep could lead to trauma or an unintended impact on the sinuses or throat, increasing the risk of aspiration. The aim is to ensure that the drops stay in the nasal cavity to provide the intended benefits, promoting effective treatment while prioritizing patient safety.
