Correct Answer: A

Rationale: Assisting the client to an upright position is the most appropriate intervention in this scenario. An upright position helps optimize lung expansion and aids in improving ventilation, which can alleviate shortness of breath. This position also assists in reducing anxiety by providing a sense of control and comfort. Administering a sedative (Choice B) may further depress the respiratory drive in a client with COPD and should be avoided unless absolutely necessary. Applying a high-flow Venturi mask (Choice C) may be indicated later based on oxygenation needs, but the immediate focus should be on positioning. Encouraging the client to drink water (Choice D) may not directly address the respiratory distress and anxiety experienced by the client.

Correct Answer: A

Rationale: Corrected Choice A: Right lower quadrant pain is a classic and key symptom of appendicitis. Pain in the right lower quadrant is typically the initial symptom and is a result of inflammation and irritation of the appendix. This pain can start around the umbilicus and then migrate to the right lower quadrant. It is important to note that appendicitis rarely presents with pain in the left lower quadrant or generalized abdominal pain. Rebound tenderness, indicated in Choice D, is a sign of peritoneal irritation and is associated with appendicitis, but it is not as characteristic as the right lower quadrant pain in the initial presentation of appendicitis.

Correct Answer: B

Rationale: The correct answer is to ask the client to describe the pain. This approach allows the nurse to gather subjective information directly from the client, such as the quality, intensity, location, and factors that aggravate or alleviate the pain. Observing body language and movement (Choice A) can provide additional cues but may not fully capture the client's pain experience. Identifying effective pain relief measures (Choice C) and providing a numeric pain scale (Choice D) are important aspects of pain management but do not directly assess the quality of the client's pain.

Correct Answer: A

Rationale: Performing chest physiotherapy is the most appropriate intervention to reduce the risk of pulmonary complications in clients with ALS. Chest physiotherapy helps mobilize and clear respiratory secretions, improving lung function and reducing the risk of complications such as pneumonia. Teaching breathing exercises (Choice B) may be beneficial for some clients, but chest physiotherapy is more specifically targeted at managing pulmonary issues in ALS. Initiating passive range of motion exercises (Choice C) and establishing a regular bladder routine (Choice D) are important interventions in ALS care but are not directly related to reducing the risk of pulmonary complications.

Correct Answer: A

Rationale: The correct answer is A. Learning is best demonstrated by a change in behavior. A client who can safely and correctly perform the procedure shows they have acquired the skill. Choice B is incorrect because critiquing the nurse's performance does not directly demonstrate the client's ability to perform the procedure. Choice C is incorrect because explaining the steps does not guarantee the client can physically perform the injection. Choice D is incorrect as answering a posttest only assesses theoretical knowledge, not practical application.
