Correct Answer: D

Rationale: Repositioning the client every 2 hours is crucial in preventing pressure ulcers from worsening. This action helps relieve pressure on specific areas, improving circulation and reducing the risk of tissue damage. Massaging the reddened area can further damage the skin, applying heat can increase the risk of skin breakdown, and elevating the head of the bed to 45 degrees may not directly address the pressure ulcer prevention. Proper positioning is essential to avoid prolonged pressure on the affected areas and promote healing.

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: C

Rationale: To ensure effective drainage, the catheter should be inserted 2-4 inches into the urethra. This length allows the catheter to reach the bladder, bypass the urethral sphincters, and ensure proper drainage without causing discomfort or injury. Using sterile gloves, cleaning the catheter with alcohol, and performing the procedure every 8 hours are not accurate instructions for self-catheterization.

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.

Correct Answer: D

Rationale: Inserting the catheter while the client is inhaling helps to align the trachea and vocal cords, reducing the risk of trauma to the respiratory tract. This technique also facilitates easier passage of the catheter into the trachea, enhancing the effectiveness of the suctioning procedure.
