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: 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: Discarding the first voiding is necessary when initiating a 24-hour urine collection to ensure that the collection starts with an empty bladder. This step helps in obtaining an accurate measurement of substances excreted over the 24-hour period without any carryover from the previous voids. Keeping the urine at room temperature or in a sterile container is not specific to the initiation of the collection. Therefore, the correct action is to discard the first voiding.

Correct Answer: C

Rationale: The ability to bear weight on both legs indicates muscle strength and stability necessary for ambulation. This skill is crucial for the client to support their body weight and move independently when standing or walking.

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.
