Correct Answer: D

Rationale: The correct answer is D: No sedation or analgesia. Neuromuscular blocking agents do not provide sedation or pain relief; they solely act on skeletal muscles to induce paralysis for procedures like intubation. Choice A is incorrect because NMB agents do not affect anxiety levels. Choice B is incorrect because NMB agents do not provide analgesia. Choice C is incorrect because NMB agents do not induce sedation. The primary purpose of NMB agents is to induce muscle paralysis without affecting consciousness or pain perception.

Correct Answer: C

Rationale: Rationale: 1. Acute tubular necrosis (ATN) is the most common intrarenal condition as it directly affects kidney tubules. 2. ATN is characterized by damage to renal tubular cells due to various factors like toxins or ischemia. 3. Prolonged ischemia (choice A) can lead to ATN but is not the most common intrarenal condition. 4. Exposure to nephrotoxic substances (choice B) can cause ATN, but ATN itself is more common. 5. Hypotension for several hours (choice D) can result in ischemia and subsequent ATN, but ATN is still the primary intrarenal condition.

Correct Answer: A

Rationale: The correct answer is A: Question the type and quantity of foods eaten in a typical day. When a child's weight is in the 95th percentile for their height, it indicates possible overweight or obesity. To address this, the nurse should assess the child's dietary habits to identify any unhealthy eating patterns contributing to excess weight. By questioning the type and quantity of foods eaten, the nurse can provide appropriate guidance on nutrition and healthy eating habits. Summary: B: Encouraging additional snacks may further contribute to weight gain and is not recommended without knowing the current eating habits. C: Recommending a high intake of whole milk may increase calorie intake and potentially worsen the weight concern. D: Assessing for signs of poor nutrition, such as a pale appearance, is important but not directly addressing the weight concern in this scenario.

Correct Answer: B

Rationale: The correct answer is B because during terminal weaning, the artificial ventilation is discontinued while maintaining the artificial airway to ensure comfort and support. This allows the patient to breathe on their own with support as needed. Explanation: 1. Option A: Complete extubation following ventilator withdrawal may not be suitable during terminal weaning as it involves removing the breathing tube entirely. 2. Option C: Discontinuation of anxiolytic and pain medications may not always be appropriate during terminal weaning as it depends on the patient's comfort needs. 3. Option D: Titration of ventilator support based on blood gas determinations is not typically done during terminal weaning as the focus is on gradual withdrawal of ventilation support while maintaining comfort.

Correct Answer: A

Rationale: The correct answer is A because in ARDS, there is a severe impairment in gas exchange leading to hypoxemia. Decreasing PaO2 levels despite increased FiO2 administration indicate poor oxygenation, a hallmark of ARDS. Elevated alveolar surfactant levels (Choice B) do not directly correlate with ARDS pathophysiology. Increased lung compliance with increased FiO2 administration (Choice C) is not characteristic of ARDS, as ARDS leads to decreased lung compliance. Respiratory acidosis associated with hyperventilation (Choice D) is not a typical finding in ARDS, as hyperventilation is usually present in an attempt to compensate for hypoxemia.
