Correct Answer: C

Rationale: Consuming a consistent amount of green leafy vegetables is important for clients taking warfarin as these foods contain vitamin K, which can affect the medication's effectiveness. Maintaining a consistent intake helps stabilize the International Normalized Ratio (INR) levels, which is crucial for monitoring the blood's ability to clot properly while on warfarin therapy.

Correct Answer: C

Rationale: Dry mucous membranes are a classic clinical manifestation of fluid volume deficit. Dehydration leads to reduced fluid intake or excessive fluid loss, resulting in decreased moisture in the mucous membranes. Bradycardia, increased skin turgor, and hypertension are not typically associated with fluid volume deficit. Bradycardia is more commonly seen in conditions like hypothyroidism or increased intracranial pressure. Increased skin turgor is a sign of dehydration, and hypertension is not a typical finding in fluid volume deficit.

Correct Answer: A

Rationale: The deltoid muscle is a common site for intramuscular injections in adults due to its accessibility and muscle mass. It is located in the upper arm and provides a sufficient area for injection. The deltoid muscle is preferred for administering vaccines and other medications that require IM administration.

Correct Answer: A

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.

Correct Answer: D

Rationale: Aspirating for blood return before injecting is a crucial step in administering intramuscular injections. This action ensures that the needle is not in a blood vessel, reducing the risk of injecting medication into a blood vessel, which can lead to potential complications.
