Correct Answer: D

Rationale: Restlessness is often a sign of respiratory distress or secretion build-up, indicating the need for suctioning. While drowsiness (choice A) can be a sign of hypoxia, it is not as immediate an indication for suctioning as restlessness. Complaint of nausea (choice B) and a pulse rate of 92 (choice C) are not directly related to the need for suctioning in a client on a volume-cycled ventilator.

Correct Answer: B

Rationale: The correct answer is 'Decreased sodium and potassium.' In acute glomerulonephritis, managing edema and oliguria is crucial. Reducing sodium and potassium intake helps achieve this by decreasing fluid retention and workload on the kidneys. Choice A, 'Decreased carbohydrates and fat,' is not directly related to managing AGN. Choice C, 'Increased potassium and protein,' is incorrect as increasing potassium can be harmful in kidney conditions. Choice D, 'Increased sodium and fluids,' is also incorrect as it can exacerbate edema and hypertension in AGN.

Correct Answer: B

Rationale: Postoperative arrhythmias are a common and potentially serious complication after cardiac surgery, making them a priority to monitor. Assessing for postoperative arrhythmias takes precedence over other assessments like checking nail beds for color and refill, auscultating for pulmonary congestion, or monitoring peripheral pulses as arrhythmias can have immediate and severe implications for the child's health.

Correct Answer: B

Rationale: The correct answer is B: Sliced turkey sandwich and canned pineapple. This lunch choice is suitable for a client with congestive heart failure as it is low in sodium. Sliced turkey is a lean protein choice, and canned pineapple is a low-sodium fruit option. Choice A contains high-sodium items like cheese and 2% milk. Choice C includes a cheeseburger, which is typically high in sodium, and a baked potato could also be high in sodium depending on preparation. Choice D consists of mushroom pizza and ice cream, both of which can be high in sodium, especially in processed or restaurant-prepared forms.

Correct Answer: B

Rationale: The correct answer is B: Pupils fixed and dilated. Fixed and dilated pupils are a critical neurological sign that indicates severe neurological damage or brain herniation, posing a significant concern for the patient's condition. Flaccid paralysis (choice A) typically indicates lower motor neuron injury, while diminished spinal reflexes (choice C) and reduced sensory responses (choice D) may suggest various neurological issues but are not as acutely concerning as fixed and dilated pupils in this scenario.
