Correct Answer: D

Rationale: Applying a hydrocolloid or foam dressing is the most effective treatment to promote healing for a Stage 2 skin ulcer. These dressings create a moist environment that supports healing and prevents further tissue damage. Option A (covering the wound with a dry dressing) can lead to drying out the wound bed, hindering healing. Option B (using hydrogen peroxide soaks) can be too harsh and may damage the surrounding healthy tissue. Option C (leaving the area open to dry) can delay healing as it does not provide the necessary moist environment for optimal wound healing.

Correct Answer: A

Rationale: Explaining the procedure to the client is the initial and most important step that the healthcare professional should take before inserting an NG tube. By explaining the procedure, the healthcare professional ensures the client's understanding, obtains informed consent, and fosters cooperation. Measuring the length of the NG tube, lubricating the tube, and positioning the client in a high Fowler's position are essential steps in the NG tube insertion process but should come after the client has been informed and consented to the procedure.

Correct Answer: A

Rationale: Veracity involves telling the truth, a fundamental ethical principle in healthcare. In this scenario, the nurse demonstrates veracity by responding honestly when the client directly asks about her cancer diagnosis. Choice B is incorrect as avoiding discussing the diagnosis to prevent emotional distress does not align with veracity and transparency. Choice C is incorrect as providing a vague answer does not uphold the principle of truthfulness. Choice D is incorrect because promising to provide information only upon client request does not address the immediate question about the cancer diagnosis and lacks transparency.

Correct Answer: C

Rationale: During puberty in males, the first physical change that typically occurs is the enlargement of the testes and scrotum. This change is due to increased production of testosterone, which stimulates growth and development of the genital organs. The appearance of downy hair on the upper lip (Choice A) and hair growth in the axillae (Choice B) usually follow the enlargement of the testes and scrotum. Deepening of the voice (Choice D) is a later stage change that occurs during puberty as the larynx (voice box) grows and the vocal cords lengthen and thicken.

Correct Answer: A

Rationale: In a situation where a client is found unresponsive on the floor, the nurse's first priority is to establish an airway. This is crucial to ensure that the client can breathe adequately and receive oxygen. Without a patent airway, the client's oxygenation and ventilation may be compromised, leading to serious consequences. Calling for assistance is important, but establishing an airway takes precedence as it directly impacts the client's ability to breathe. Checking the client's pulse and blood pressure can be done after ensuring a clear airway. Performing CPR is not the immediate action needed unless the client's breathing and pulse are absent after the airway has been secured.
