Correct Answer: B

Rationale: The priority when managing a client with a chest tube postoperatively is to check for air leaks and ensure the proper functioning of the chest tube. This is crucial to prevent complications such as pneumothorax or hemothorax. Clamping the chest tube intermittently can lead to a buildup of pressure in the pleural space and should not be done without a specific medical indication. Encouraging deep breathing and coughing helps with lung expansion but is not the priority over ensuring the chest tube's proper function. Encouraging frequent coughing may increase the risk of dislodging the chest tube or causing complications.

Correct Answer: C

Rationale: Instructing the client to focus on gradually resuming self-care tasks is the most appropriate strategy to promote independence following an acute myocardial infarction. This approach allows the client to regain confidence and control over their self-care activities without feeling overwhelmed. Requesting an occupational therapy consult (Choice A) may be beneficial but is not the immediate solution to promote independence. Assigning assistive personnel (Choice B) to perform tasks for the client does not encourage independence. Asking if a family member is available for assistance (Choice D) does not directly promote the client's independence.

Correct Answer: B

Rationale: When caring for a client experiencing delirium, it is essential to identify the underlying causative condition or illness. Delirium can be caused by various factors such as infections, medication side effects, dehydration, or underlying health conditions. By identifying the root cause, appropriate treatment can be provided. Controlling behavioral symptoms with low-dose psychotropics (Choice A) may be considered in some cases but is not the primary essential step. Manipulating the environment to increase orientation (Choice C) can help manage symptoms but does not address the underlying cause. Decreasing or discontinuing all previously prescribed medications (Choice D) should only be done under medical supervision, as some medications may be necessary for the client's well-being.

Correct Answer: A

Rationale: The correct answer is to maintain a patent airway and monitor for infection. These are crucial nursing interventions for patients with tracheostomies to ensure adequate oxygenation and prevent complications. Suctioning airway secretions and providing humidified oxygen can be part of the care plan but are not as essential as maintaining a patent airway. Educating the patient on self-care and tracheostomy cleaning is important for long-term management but is not as immediate as ensuring a patent airway and monitoring for infection. Changing tracheostomy ties daily is a specific task related to tracheostomy care but is not as critical as ensuring the airway is clear and infection-free.

Correct Answer: A

Rationale: The correct answer is A. In older adults, key signs of a UTI often include confusion and increased temperature. Confusion is a common symptom in the elderly when they have a UTI, and an increase in body temperature can indicate an infection. Choices B, C, and D are incorrect because while painful urination and frequent urination are common UTI symptoms in general, they may not be as prominent in older adults. Dizziness, headache, back pain, and fever can be associated with other conditions but are not typically key signs of a UTI in older adults.
