Correct Answer: B

Rationale: The correct answer is B: Administer intravenous fluids. In a client with severe burn injury, the priority intervention is to administer intravenous fluids to prevent shock. Monitoring urine output (Choice A) is important but not the priority. Applying cool, moist compresses (Choice C) can be beneficial but is not the priority over fluid resuscitation. Covering the burn area with a sterile dressing (Choice D) is important for wound care but is not the immediate priority in managing severe burns.

Correct Answer: A

Rationale: The correct answer is A: Administer sublingual nitroglycerin. Sublingual nitroglycerin is the first-line treatment for chest pain related to coronary artery disease. It helps dilate the coronary arteries and improve blood flow to the heart, providing immediate relief from ischemia. Administering nitroglycerin promptly can help alleviate the chest pain and prevent further complications. Obtaining a 12-lead electrocardiogram (Choice B) is important but should not delay the administration of nitroglycerin. Calling the healthcare provider (Choice C) can be done after initiating immediate treatment. Checking the client's oxygen saturation (Choice D) is relevant but not the first action to take in this scenario.

Correct Answer: B

Rationale: An oxygen saturation of 88% indicates hypoxemia, which is a critical condition requiring immediate intervention to improve oxygenation. Hypoxemia can lead to tissue hypoxia and further complications. A productive cough with yellow sputum is common in pneumonia but may not require immediate intervention unless it worsens or is associated with other concerning symptoms. A respiratory rate of 20 breaths per minute is within the normal range, indicating adequate ventilation. A heart rate of 90 beats per minute is also within a normal range and may not require immediate intervention unless it is accompanied by other abnormal findings.

Correct Answer: A

Rationale: The correct action for the charge nurse to implement is to remind the client that nurse assignments are not based on patient requests. In this situation, it is essential to establish boundaries and communicate that nurse assignments are made based on clinical decisions, not patient preferences. Option B is incorrect because it compromises the principle of fairness in nurse assignments. Option C is incorrect as it encourages the client's behavior by allowing him to request a different nurse based on personal preferences. Option D is also incorrect as it does not address the issue of patient manipulation and reinforces inappropriate behavior.

Correct Answer: A

Rationale: The correct answer is A: 'Frequent syncope.' Orthostatic hypotension, common in Parkinson's disease, often causes syncope (fainting) when blood pressure drops upon standing. This information is critical for planning safe blood pressure measurements, ensuring readings are taken in both lying and standing positions to assess for sudden drops in pressure. Muscle rigidity, tremors, or gait instability are important symptoms in Parkinson's disease but are not directly related to blood pressure assessment.
