Correct Answer: B

Rationale: Measuring the client's oxygen saturation level is the most important assessment in this scenario. Oxygen saturation level reflects how well the client is oxygenating, which is crucial in assessing the effectiveness of oxygen therapy for a client with COPD. Monitoring the respiratory rate and effort (Choice A) is important but assessing oxygenation with saturation levels takes precedence. While arterial blood gas levels (Choice C) provide comprehensive information, checking oxygen saturation is a quicker and more immediate way to assess oxygenation status. Checking blood pressure (Choice D) is not the priority when evaluating the effectiveness of oxygen therapy in COPD.

Correct Answer: C

Rationale: Chest physiotherapy is essential for clients with amyotrophic lateral sclerosis (ALS) to prevent atelectasis and pneumonia. Chest physiotherapy aids in clearing secretions, maintaining lung function, and preventing respiratory complications. Active and passive range of motion exercises (Choice A) are important for maintaining joint mobility but are not directly associated with preventing atelectasis and pneumonia in ALS. Incentive spirometer use every 4 hours (Choice B) is beneficial for lung expansion and preventing atelectasis but may not be as effective as chest physiotherapy in managing secretions. Repositioning every 2 hours (Choice D) is crucial for preventing pressure ulcers but is not directly related to preventing atelectasis and pneumonia in ALS.

Correct Answer: A

Rationale: The correct answer is A. Regulating oxygen flow at no more than 6 L/min via nasal cannula is a safe practice to prevent potential complications such as oxygen toxicity. Option B suggesting administering oxygen at a higher flow rate for better saturation is incorrect as it can lead to adverse effects. Option C is incorrect because using a high-flow nasal cannula for all clients is not necessary and should be based on individual client needs. Option D is incorrect as adjusting oxygen flow solely based on client comfort without considering the prescribed flow rate can compromise the effectiveness of oxygen therapy.

Correct Answer: D

Rationale: The correct answer is D because monitoring the color of a client's urinary output is a task that can be safely delegated to assistive personnel. This task involves basic observation and does not require specialized nursing knowledge or skills. Choice A is incorrect because reporting ABG results to the provider requires interpretation and critical thinking skills typically performed by a nurse. Choice B is incorrect as instructing a client about how to use an incentive spirometer involves educating and assessing the client, which is a nursing responsibility. Choice C is incorrect as administering enteral feeding to a client with a gastrostomy tube requires nursing expertise to ensure proper technique and monitoring for complications.

Correct Answer: D

Rationale: Choice D is the correct response. The body's receptors adapt to the heat over time, which can explain why the client no longer perceives the warmth from the heating pad. This phenomenon is known as thermal adaptation. Choices A, B, and C are incorrect. Choice A is inaccurate because the client not feeling the warmth does not necessarily mean they have derived the maximum benefit. Choice B incorrectly states that blood vessels dilating remove heat, which is not accurate. Choice C suggests increasing the temperature when the pad no longer feels warm, which could potentially lead to burns or discomfort for the client.
