Correct Answer: B

Rationale: Practicing pursed-lip breathing is an essential technique to help manage COPD as it can improve oxygenation by promoting better gas exchange. This technique helps to keep the airways open longer during exhalation, preventing air trapping and improving breathing efficiency. Increasing fluid intake can help thin secretions, which is beneficial, but it is not the primary instruction for managing COPD. Avoiding physical activity is not recommended as it can lead to deconditioning and worsen dyspnea in COPD patients. Using a peak flow meter is more commonly associated with monitoring asthma rather than COPD, so it is not the most relevant instruction for managing COPD.

Correct Answer: A

Rationale: The correct response is to ask the client about their concerns regarding being without their teeth. This approach helps address the client's anxiety and provides insight into the reason for their agitation. Choice B is authoritarian and does not address the client's emotional needs. Choice C focuses on the technical aspect of surgery and does not address the client's emotional state. Choice D implies a one-way communication without addressing the client's feelings or concerns.

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.

Correct Answer: A

Rationale: The appropriate nursing action when an irregularity in the heart rate is observed is to count the apical pulse rate for a full minute and describe the rhythm in the chart. This approach helps in obtaining an accurate assessment of the irregularities present. Measuring the blood pressure (Choice B) is important but not the immediate priority when an irregular heart rate is noted. Performing an ECG (Choice C) may be necessary but is a more advanced intervention that should follow the initial assessment. Rechecking the heart rate after 5 minutes (Choice D) may delay potential interventions for addressing the irregularity, making it less appropriate than the immediate assessment and documentation of the pulse rhythm.

Correct Answer: B

Rationale: The correct answer is B. Providing supportive nursing care, such as applying emollients and reinforcing the dressing on the pressure ulcer, meets the immediate needs of the client and is in line with legal and professional standards. Option A is incorrect because increasing activity may not be directly related to the immediate skin care needs of the client. Option C is incorrect as debridement might not be immediately necessary based on the initial assessment. Option D is incorrect as nurses are often authorized to initiate treatments within their scope of practice without waiting for healthcare provider prescriptions, especially for routine care like skin moisturization and dressing reinforcement.
