What should be done before giving nasal medication to ensure effectiveness?

Before administering nasal medication, having the client blow their nose is essential because clearing nasal passages of mucus can significantly enhance the absorption of the medication. When the nose is congested or filled with mucus, it can act as a barrier, reducing the effectiveness of the medication by limiting its ability to reach the targeted area for optimal action. Ensuring that the nasal passages are unobstructed allows the medication to be delivered more effectively to the nasal mucosa, facilitating better therapeutic outcomes.

Positioning the client upright is beneficial for overall comfort and can aid in efficient medication delivery, but it is not as critical for ensuring effectiveness as clearing the nasal passages. Raising the client's arms or having them sip water does not specifically contribute to the absorption or effectiveness of nasal medications.
