Slightly tilting the head back after receiving nose drops allows for better distribution of the medication within the nasal passages. This position helps the drops to flow more evenly across the mucous membranes, ensuring that the medication can be absorbed effectively and reach the targeted areas. When the head is tilted back, gravity assists in the process, promoting easier access for the drops to coat the nasal tissues.

Other choices might suggest actions that could either hinder the medication's effectiveness or are not advisable following the application of nasal drops. For instance, swallowing might not help the drops achieve their intended effect, as they are meant for nasal absorption, and exhaling deeply could potentially force the medication out. Closing one nostril does not facilitate proper distribution, as the drops need to interact with the entire nasal cavity. Thus, the instruction to slightly tilt the head back is the most effective way to ensure proper medication delivery through nasal drops.
