Correct Answer: B

Rationale: The correct answer is B: Zolpidem. Zolpidem is a sedative-hypnotic medication that can worsen altered mental status, especially in clients who are already aggressive. Therefore, the nurse should clarify this prescription with the provider before administration to ensure it is safe for the client. Choice A, Haloperidol, is an antipsychotic commonly used to manage aggression in clients with altered mental status, making it an appropriate choice in this scenario. Choice C, Morphine, is an opioid analgesic and would not directly impact the client's altered mental status or aggression. Choice D, Lorazepam, is a benzodiazepine used to manage anxiety and agitation, which could be beneficial in this situation but does not have the same potential to exacerbate altered mental status as Zolpidem.

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 A: Hypertension, high cholesterol, and smoking are major risk factors for stroke. These factors contribute to the development of atherosclerosis, which can lead to a stroke. While obesity and lack of exercise are risk factors for cardiovascular diseases, they are not as directly linked to stroke as hypertension, high cholesterol, and smoking. Family history of cardiovascular disease may increase the overall risk of heart problems, but it is not as specific to stroke as the factors listed in option A. Age and gender can influence the risk of stroke, but they are not modifiable risk factors like hypertension, high cholesterol, and smoking, which can be reduced through lifestyle changes.

Correct Answer: B

Rationale: The correct answer is to instruct the client to sit quietly for 5 minutes before taking their blood pressure. This is important because sitting quietly helps stabilize the heart rate, leading to a more accurate reading. Choice A is incorrect because taking blood pressure after eating can affect the readings. Choice C is wrong because using a blood pressure cuff that is too small can provide inaccurate readings. Choice D is also incorrect as blood pressure should be taken in a seated position for accurate results.

Correct Answer: A

Rationale: The correct answer is to check for air leaks in the tubing every 4 hours when caring for a client with a chest tube. This responsibility is crucial because it ensures proper chest tube function and helps prevent complications such as pneumothorax or hemothorax. Clamping the chest tube (Choice B) can lead to serious issues by causing a tension pneumothorax. Encouraging deep breathing and coughing (Choice C) is important for respiratory hygiene but is not directly related to chest tube care. Keeping the client in a high Fowler's position (Choice D) may be beneficial for some conditions but is not specific to chest tube management.
