A nurse is preparing to discharge an emergency department patient who has been fitted with a sling to support her arm after a clavicle fracture. What should the nurse instruct the patient to do?

Correct Answer: D

Rationale: The correct answer is D because using the arm for light activities within the range of motion helps prevent stiffness and muscle atrophy. It promotes blood circulation and aids in the healing process without putting excessive strain on the fracture site. Explanation: - Choice A: Elevating the arm above the shoulder could increase swelling and impede circulation, leading to complications. - Choice B: Immobilizing the elbow, wrist, and fingers can result in joint stiffness and muscle weakness, hindering recovery. - Choice C: Engaging in active range of motion with the affected arm can be too strenuous and may disrupt the healing process by causing further damage to the fracture site.

Correct Answer: B

Rationale: The correct answer is B because changing the bandage daily helps prevent infection and promotes wound healing. This statement also demonstrates understanding of proper post-biopsy care. Choice A is incorrect as showering is typically allowed after a punch biopsy. Choice C is incorrect as some blood on the dressing is normal post-biopsy. Choice D is incorrect as it takes time for the biopsy site to heal, and it's not uncommon for it to take longer than a few days.

Correct Answer: A

Rationale: The correct answer is A: Apply splints. Splints help maintain proper positioning of joints to prevent contractures in burn patients. Splints provide support and protect the joints during the healing process. They help to prevent shortening and tightening of muscles and tissues, reducing the risk of contractures. B: Physical therapy two hours a day is not the most effective approach for preventing contractures in burn patients. While physical therapy is important for rehabilitation, excessive duration may not necessarily prevent contractures. C: Passive range of motion exercises are beneficial for maintaining joint flexibility, but they may not provide enough support to prevent contractures in burn patients. D: Occupational therapy one hour every other day focuses on activities of daily living and may not directly address the prevention of contractures.

Correct Answer: C

Rationale: Rationale: C: Zinc is essential for protein synthesis, aiding in wound healing, crucial for pressure ulcer recovery. A: Strengthening capillaries is more related to vitamin C. B: Immune function is supported by zinc, but not the primary reason for pressure ulcer treatment. D: Red blood cell formation mainly requires iron, not zinc.

Correct Answer: D

Rationale: The correct answer is D because all the choices listed (A, B, and C) are types of general receptors located in the skin. Meissner's corpuscles and Pacinian corpuscles are encapsulated receptors responsible for detecting touch and pressure, while free nerve endings are unencapsulated receptors that respond to pain, temperature, and pressure. Therefore, selecting "All of the above" encompasses all four types of general receptors present in the skin.
