Correct Answer: D

Rationale: In the event of accidental poisoning, it is crucial to know the child's age and weight to determine the appropriate treatment. This information helps healthcare providers calculate the correct dosage of antidotes or medications needed based on the child's size and age. The child's age and weight play a significant role in managing accidental poisoning cases. Therefore, this information should be a priority for parents to communicate in such emergencies. Choices A, B, and C are not as critical as the child's age and weight when it comes to immediate treatment decisions for accidental poisoning.

Correct Answer: A

Rationale: The correct answer is A: 'Keep a nightlight on in the bathroom.' This safety measure is crucial for older adults to prevent falls by enhancing visibility during nighttime bathroom visits. Choice B is incorrect because setting the room temperature to 68 degrees Fahrenheit may not be universally suitable for all older adults, as individual preferences vary. Choice C is incorrect as placing throw rugs over electrical cords poses a tripping hazard rather than enhancing safety. Choice D is incorrect as using chairs without armrests may not provide adequate support and stability for older adults, increasing the risk of falls.

Correct Answer: A

Rationale: The correct answer is A: Hypertension. Pheochromocytoma is characterized by the overproduction of catecholamines, leading to symptoms such as hypertension. Bradycardia (Choice B) is not typical in pheochromocytoma as increased catecholamines usually lead to tachycardia. Hypoglycemia (Choice C) and weight gain (Choice D) are not commonly associated symptoms of pheochromocytoma.

Correct Answer: A

Rationale: Swelling and coolness at the IV site can indicate complications such as infiltration, which can lead to tissue damage or fluid leakage into the surrounding tissues. Prompt removal of the IV catheter is essential to prevent further complications. The client reporting mild discomfort at the insertion site is common during IV therapy and does not necessarily warrant catheter removal unless there are signs of infiltration. A slower than expected infusion rate may not always necessitate IV catheter removal; the nurse should troubleshoot potential causes such as kinks in the tubing or pump malfunctions first. Just because the IV catheter is no longer needed for treatment does not automatically mean it should be removed; proper assessment and monitoring for complications are still essential.

Correct Answer: A

Rationale: Encouraging the client to use an incentive spirometer regularly is crucial in preventing postoperative complications after abdominal surgery. This action helps prevent atelectasis by promoting lung expansion and improving air exchange in the lungs, reducing the risk of respiratory complications. Assisting the client in ambulating early is important for preventing issues like deep vein thrombosis but may not directly address respiratory concerns postoperatively. Positioning the client in high Fowler's position can help with respiratory distress but is not as specific to preventing postoperative respiratory complications as using an incentive spirometer. While encouraging the client to cough and deep breathe is generally beneficial for lung expansion, using an incentive spirometer is more effective and targeted in preventing atelectasis after abdominal surgery.
