Correct Answer: A

Rationale: Encouraging pursed-lip breathing is essential for clients with COPD as it aids in improving ventilation and gas exchange. This technique helps keep the airways open longer during exhalation, preventing air trapping and promoting more effective breathing. Administering oxygen, placing the client in a supine position, or restricting fluid intake are not primary interventions for managing COPD and may not address the specific respiratory needs of the client.

Correct Answer: B

Rationale: Elevating the head of the bed to 30-45 degrees during feedings is essential to prevent aspiration in clients receiving enteral nutrition. This positioning helps decrease the risk of regurgitation and aspiration by supporting proper digestion and aiding food passage through the gastrointestinal tract. Elevating the head of the bed is a standard precautionary measure recommended to reduce the chances of aspiration and should be consistently implemented during feedings to ensure client safety and optimal enteral nutrition delivery.

Correct Answer: C

Rationale: The primary purpose of therapeutic communication in healthcare is to establish a therapeutic relationship between the healthcare provider and the client. Through effective communication, trust, empathy, and understanding can be fostered, which are essential for providing quality care and promoting positive health outcomes. Building a therapeutic relationship enhances patient satisfaction, improves adherence to treatment plans, and increases the likelihood of successful health outcomes.

Correct Answer: C

Rationale: Aspirating before injecting the medication is a crucial step in IM injections to check for blood return, ensuring that the needle is not in a blood vessel. This technique helps prevent accidental intravascular injection of the medication, reducing the risk of complications such as inadvertent intravenous administration of the substance.

Correct Answer: A

Rationale: Placing a pillow between the client's legs is crucial post hip arthroplasty surgery to prevent hip dislocation. This intervention helps maintain proper alignment and prevents legs from crossing midline, reducing the risk of hip prosthesis dislocation. Elevating the head of the bed to 45 degrees, positioning the client on the operative side, or keeping the client's legs adducted are not recommended postoperative interventions for a total hip arthroplasty, as they can increase the risk of complications and compromise the surgical site.
