Correct Answer: D

Rationale: Chronic pain is typically defined as pain lasting longer than 3-6 months or persisting after the expected time for tissue healing. Episodic back pain following a fall 2 years ago fits the criteria for chronic pain. Option A describes acute pain related to a recent fracture. Option B describes acute postoperative pain. Option C describes acute pain associated with an acute condition (food poisoning). Therefore, the correct identification of a client experiencing chronic pain is the one with episodic back pain from a past injury, as it has lasted beyond the normal healing time.

Correct Answer: C

Rationale: The correct answer is 'C: Justice.' Justice in healthcare ethics involves fairness and providing equal treatment to all individuals in similar situations. In this scenario, ensuring that all clients waiting for a kidney transplant meet the same qualifications aligns with the principle of justice by offering equal opportunities for transplantation. Choice A, 'Fidelity,' pertains to keeping promises and being loyal to patients, not the equal treatment of individuals. Choice B, 'Autonomy,' refers to respecting patients' rights to make decisions about their own care, which is not directly related to the equal qualifications for kidney transplants. Choice D, 'Nonmaleficence,' focuses on the obligation to do no harm, which is important in healthcare but not the primary ethical principle demonstrated in this scenario.

Correct Answer: C

Rationale: The nurse most likely observed plantar warts, which appear on the sole of the foot and are caused by the papillomavirus. Corns (Choice A) and calluses (Choice B) are areas of thickened skin caused by pressure or friction and are not typically associated with viruses. Athlete's foot (Choice D) is a fungal infection that usually affects the skin between the toes and is not caused by a virus like plantar warts.

Correct Answer: D

Rationale: The correct answer is to assist the client to an upright position. When a client is having difficulty breathing, promoting optimal oxygenation is essential. Elevating the head of the bed improves ventilation and lung expansion by reducing pressure on the diaphragm. This position allows the lungs to expand fully, enhancing oxygen exchange. Suctioning the airway may be necessary if there are secretions causing obstruction, but it is not the first intervention in this scenario. Administering a bronchodilator is appropriate for bronchoconstriction but does not address the immediate need for better ventilation. Increasing humidity can be beneficial in certain respiratory conditions, but it is not the initial priority when a client is struggling to breathe.

Correct Answer: A

Rationale: Removing restraints one at a time is the correct action to take when caring for a client in soft wrist restraints. This approach ensures safety and comfort while still maintaining the necessary restrictions. Choice B is incorrect as securing the restraints tightly can lead to circulatory issues and discomfort. Choice C of checking the restraints every hour is a reasonable action, but it is not the priority when compared to the correct choice of removing the restraints one at a time. Choice D of using leather restraints for additional security is unnecessary and may be more restrictive and uncomfortable for the client.
