Correct Answer: A

Rationale: The correct answer is A: Hydrocolloid. Hydrocolloid dressings are recommended for stage 2 pressure injuries as they help maintain a moist wound environment, which supports the healing process. Gauze (choice B) is not ideal for stage 2 pressure injuries as it can stick to the wound bed and disrupt the healing process. Transparent film dressings (choice C) are more suitable for superficial wounds or as a secondary dressing. Alginate dressings (choice D) are typically used for wounds with heavy exudate, which is not typically seen in stage 2 pressure injuries.

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: D

Rationale: A positive Homans' sign is a classic sign associated with deep vein thrombosis (DVT) and indicates the presence of a blood clot. This finding is crucial to report to the healthcare provider promptly for further evaluation and treatment. Swelling, redness, pain, warmth, and tenderness in the affected leg are common signs of DVT, but a positive Homans' sign specifically points towards a potential blood clot, making it the priority finding to be reported. Reporting other symptoms may also be important, but a positive Homans' sign is more specific to DVT and requires immediate attention.

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 correct answer is C: Friction. The amount of friction is crucial in effective hand hygiene to remove microorganisms. Rubbing hands together with friction helps to dislodge and remove dirt, oils, and microorganisms. While temperature and soap are important factors in hand hygiene, the mechanical action of friction plays a more significant role in physically removing contaminants. Time is also important in hand hygiene practice, but without adequate friction, the effectiveness of the process is compromised.
