What should a client do before receiving nasal medication?

Before receiving nasal medication, a client should blow their nose. This action is essential because it clears the nasal passages of mucus and other obstructions, allowing for better absorption of the medication. When the nasal passages are clear, the medication can reach its target more effectively, enhancing its efficacy.

Blowing the nose helps create an optimal environment for the medication to work by removing any potential barriers and ensuring that the dose is adequately delivered to the mucous membranes of the nasal cavity. This step is particularly important for medications that rely on nasal absorption for systemic effects, as any excess mucus could dilute the medication and hinder its action.

In contrast, drinking water, lying down, or closing one's eyes do not directly contribute to the effectiveness of nasal medication and may not be necessary preparatory steps.
