Correct Answer: D

Rationale: Redness and warmth of the affected limb are classic signs of deep-vein thrombosis (DVT) due to inflammation and increased blood flow. These symptoms occur as a result of the blood clot obstructing normal blood flow and causing localized inflammation in the affected limb. Swelling of the affected limb, diminished peripheral pulses, and coolness are not typically associated with DVT. Swelling can be present but is often accompanied by the characteristic redness and warmth. Diminished pulses and coolness are more indicative of arterial insufficiency rather than venous thrombosis.

Correct Answer: B

Rationale: Verifying the client's identity is the essential initial step before administering a blood transfusion. This action is crucial to confirm that the correct blood product is being administered to the right client, thereby preventing any potential errors or adverse reactions. Ensuring patient safety is paramount in healthcare, and verifying the client's identity is a fundamental safety measure that should always be prioritized.

Correct Answer: D

Rationale: When caring for a client with dysphagia, placing food on the unaffected side of the mouth can help them chew and swallow more effectively. This technique can assist in minimizing the risk of aspiration and improve the client's ability to manage food safely. Providing small food pieces, offering thickened liquids, and encouraging the client to sit upright after meals are also important interventions in managing dysphagia, but placing food on the unaffected side of the mouth is a specific technique that directly addresses the swallowing difficulty associated with dysphagia.

Correct Answer: B

Rationale: The client's self-report of pain is the most reliable indicator of pain. Pain is a subjective experience, and the client's self-report provides direct insight into their perception of pain intensity, quality, and impact on daily life. Vital signs, body language, and medical history can offer additional information but may not accurately reflect the client's actual pain experience. Therefore, relying on the client's self-report ensures a more accurate assessment of their pain and helps in tailoring appropriate interventions and treatment plans.
