Correct Answer: A

Rationale: The correct intervention for a client with Alzheimer's disease in an extended care facility is to plan to have the same nursing staff provide care whenever possible. Consistency in caregivers helps reduce confusion and anxiety in clients with Alzheimer's disease, promoting a stable and supportive environment for the client. Choice B is incorrect as it focuses on activities rather than the consistency of caregivers. Choice C is incorrect as it suggests isolating the client, which can lead to increased confusion and distress. Choice D is incorrect as introducing the client to new people immediately can be overwhelming and may exacerbate their symptoms.

Correct Answer: D

Rationale: Fatigue is a common side effect of radiation therapy. In this scenario, the appropriate action for the nurse to take is to reinforce the importance of rest and adequate sleep. It is crucial to address the client's increasing fatigue by promoting self-care strategies such as additional rest periods and ensuring plenty of sleep. Rescheduling the treatment is not necessary for fatigue, and vital sign monitoring every 30 minutes may not directly address the client's reported symptom. Notifying the healthcare provider or charge nurse immediately is not the first-line intervention for increasing fatigue, as this symptom can be managed through education and self-care recommendations.

Correct Answer: C

Rationale: Maintaining system integrity is essential to promote lung reexpansion in postoperative patients with chest tubes. Clamping the chest tube abruptly can lead to tension pneumothorax, a life-threatening condition. The bubbling observed is a normal sign indicating that the system is functioning correctly, as it allows the drainage of air or fluid from the pleural space. Notifying the registered nurse may be necessary if there are significant concerns or changes observed, but the immediate action should be to ensure system integrity and lung reexpansion.

Correct Answer: C

Rationale: The symptoms of uncontrollable hand movements and excessive blinking are indicative of tardive dyskinesia, a possible side effect of long-term use of psychotropic medications. Reviewing the screening for tardive dyskinesia is crucial to assess if these symptoms are related to the medication. Option A, the prescription for lorazepam, is less relevant as the focus should be on potential side effects rather than the specific medication. Option B, history of Parkinson's disease, is not directly related to the observed symptoms, which are more likely linked to medication side effects. Option D, recent urine drug screen report, is not as pertinent in this context compared to reviewing the screening for tardive dyskinesia.

Correct Answer: B

Rationale: Checking the pH of the aspirate is the most reliable method to confirm nasogastric tube placement as it provides direct evidence of the tube's location in the stomach. When the pH is acidic (pH < 5), it indicates that the tube is correctly placed in the stomach. Auscultating over the stomach while injecting air may not always be accurate, as the sound can be misleading due to various factors. Observing the patient's response during feeding is not a definitive method for confirming tube placement, as it can be influenced by other factors. Measuring the external length of the tube does not ensure correct placement within the GI tract and can be affected by external factors like patient anatomy.
