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: Fresh fruits are naturally low in sodium, making them a suitable choice for a low-sodium diet. They provide essential nutrients and are a healthy option for individuals who need to limit their sodium intake.

Correct Answer: C

Rationale: When administering an intradermal injection, a tuberculin syringe is the appropriate choice due to its small size and precise measurement markings, which are essential for accurately delivering the medication into the dermis layer of the skin. Using a 1-inch needle (choice A) is more common for subcutaneous injections, while inserting the needle at a 45-degree angle (choice B) is typical for intramuscular injections. Aspirating before injecting (choice D) is not necessary for intradermal injections, as the goal is to deliver the medication into the dermis rather than a blood vessel.

Correct Answer: B

Rationale: When administering a subcutaneous injection, it is important to insert the needle at a 90-degree angle to ensure proper medication delivery into the subcutaneous tissue. This angle helps prevent the medication from being injected too deeply or too superficially, ensuring optimal absorption and therapeutic effect.

Correct Answer: A

Rationale: Monitoring gastric residuals every 4 hours is essential to assess the stomach's ability to empty properly, reducing the risk of aspiration. It helps in determining if the feedings are being tolerated by the client and if adjustments are needed in the feeding regimen. Positioning the client in a semi-Fowler's position helps prevent reflux and aspiration by promoting proper digestion and emptying of the stomach contents. Checking for tube placement by auscultating air after feeding confirms correct tube placement in the stomach. Warming the formula to body temperature before feeding enhances client comfort but does not directly prevent aspiration.
