Correct Answer: B

Rationale: The correct answer is to keep the head of the bed at 30 degrees. This position helps reduce the risk of aspiration and improves ventilation. Suctioning the airway every hour may lead to mucosal damage and increase the risk of infection. Changing the ventilator tubing every day is not necessary unless there are specific indications to do so, as it can increase the risk of contamination and infection. Administering a bronchodilator every 2 hours is not a standard practice and should be done based on the client's individualized treatment plan.

Correct Answer: B

Rationale: Weighing the client daily to monitor fluid balance is crucial for clients with heart failure. This intervention helps assess for fluid retention or depletion, providing valuable information for managing the condition effectively. Encouraging increased fluid intake (Choice A) is contraindicated in heart failure as it can worsen fluid overload. Restricting fluid intake during meals (Choice C) may lead to dehydration, which is harmful for clients with heart failure. Limiting daily activity (Choice D) is not recommended as appropriate activity levels should be encouraged for overall well-being, under guidance to prevent excessive fatigue.

Correct Answer: B

Rationale: The correct answer is to monitor the client's weight daily to assess fluid balance in clients with heart failure. This intervention helps healthcare providers evaluate fluid retention or loss, which is crucial in managing heart failure. Choice A is incorrect because excessive fluid intake can worsen heart failure symptoms by causing fluid overload. Choice C is incorrect because increasing sodium intake can lead to fluid retention, exacerbating heart failure. Choice D is incorrect as limiting fluid intake excessively can also be harmful in heart failure management, potentially leading to dehydration.

Correct Answer: A

Rationale: Correct Answer: Increasing the client's oxygen flow rate should be the nurse's first action. Hypoxia is a common complication of pneumonia and can lead to confusion. Providing adequate oxygenation is essential in addressing hypoxia and improving the client's condition.\nOption B: Obtaining vital signs is important but addressing hypoxia takes precedence in the setting of new onset confusion.\nOption C: Administering an antibiotic is important for treating pneumonia but addressing hypoxia and confusion is the priority.\nOption D: Notifying the provider may be necessary but addressing the immediate physiological need of oxygenation should come first.

Correct Answer: C

Rationale: The correct answer is C: Irritability and agitation that worsen throughout the day. These symptoms are concerning in a client diagnosed with delirium as they may indicate an exacerbation of the condition or an underlying cause that requires immediate attention. Option A describes symptoms that resolve with rest, which may not be as urgent. Option B provides a normal blood pressure reading, which is not typically associated with immediate attention in delirium cases. Option D describes mild confusion during specific hours, which may not be as critical as worsening symptoms throughout the day.
