Rationale: Shaking the inhaler before use is crucial to ensure proper mixing of the medication inside the inhaler. This action helps to disperse the medication evenly, allowing for consistent dosing during inhalation. Breathing out forcefully, taking the medication with food, and using a spacer are not related to the correct use of a metered-dose inhaler and may not lead to optimal medication delivery.

Rationale: Flushing the NG tube with water before and after administering medications is essential to prevent clogging of the tube and ensure proper delivery of medication. This practice helps maintain tube patency and decreases the risk of obstruction, which could compromise the client's treatment and nutrition. By flushing the tube, the healthcare provider ensures that the medication is completely delivered and that there are no residual drug particles left in the tube, which could lead to blockages or inconsistent dosing. Therefore, flushing the NG tube is a crucial step in the safe administration of medications to clients receiving enteral feedings.

Correct Answer: C

Inhaling the medication quickly ensures effective delivery of the dry powder to the lungs, maximizing its therapeutic effects. Options A, B, and D are incorrect as shaking the DPI, taking it with food, and using a spacer are not recommended practices for DPI administration.
