What should a client do before receiving nasal medication?

Before receiving nasal medication, it is important for a client to blow their nose. This action helps to clear the nasal passages of any mucus or debris that could potentially block the absorption of the medication. Proper absorption is crucial for the medication to work effectively, as nasal sprays often target specific areas within the nasal cavity. By ensuring that the nasal passages are clear, the client maximizes the chances of the medication reaching its intended site of action and achieving the desired therapeutic effect.

Other options, while they may have some relevance to the medication process, do not directly enhance the efficacy of nasal medication in the same way. For instance, drinking water might be important for hydration but doesn't affect nasal absorption, lying down may not be necessary or beneficial for administering nasal sprays, and closing the eyes is not relevant to the process of delivering medication through the nose.
