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: B

Rationale: Eating a snack before exercising is crucial for managing blood sugar levels and preventing hypoglycemia in individuals with diabetes. Exercising on an empty stomach can lead to low blood sugar levels, but consuming a snack before physical activity helps stabilize blood sugar and provides energy for the body. This proactive approach demonstrates the client's understanding of the importance of managing blood sugar levels during physical activity.

Correct Answer: A

Rationale: Emptying the colostomy bag when it is half full is crucial to prevent leakage and detachment from the skin. This practice helps to maintain the integrity of the colostomy system, reducing the risk of skin irritation and odor. It is essential for client comfort and overall stoma care.

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: Administering the injection slowly is the recommended technique to reduce discomfort associated with IM injections. This approach allows the medication to disperse more gradually into the muscle, minimizing the sensation of pressure or pain during administration. Administering the injection slowly can also help prevent tissue damage and reduce the likelihood of injection site reactions.
