A registered nurse (RN) is assigned to work at the Poison Control Center telephone hotline. In which of these cases of childhood poisoning would the nurse suggest that parents have the child drink orange juice?

Correct Answer: B

Rationale: Orange juice neutralizes mild plant toxins like philodendron; others require urgent care.

Correct Answer: B

Rationale: Regular range-of-motion exercises are vital to prevent complications like joint stiffness, muscle atrophy, and blood clots in patients with limited mobility post-surgery. These exercises maintain circulation and flexibility, countering the risks of prolonged stillness. Avoiding hydration increases dehydration risk and doesn't address immobility's effects it's counterproductive. Keeping the patient supine at all times exacerbates immobility issues, potentially leading to pressure ulcers or respiratory problems. Minimizing communication might reduce stress but doesn't tackle physical complications. Nurses use active or passive exercises depending on the patient's ability, ensuring joints stay functional and reducing the likelihood of thromboembolism or contractures, which are serious post-operative concerns.

Correct Answer: D

Rationale: A thorough physical examination provides a comprehensive assessment of nutritional status by evaluating signs like muscle wasting, skin condition, hair health, and edema, alongside weight and lab data. Family dietary reports are subjective and incomplete without clinical correlation. Relying only on weight misses underlying issues like fluid retention or muscle loss. Monitoring intake and output tracks fluid balance but not nutrient absorption or deficiencies. A full exam integrates physical findings with history and tests, offering a holistic view critical for identifying malnutrition or overnutrition and guiding tailored interventions in nursing care.

Correct Answer: D

Rationale: Using handrails and non-slip mats reduces fall risk in patients with impaired mobility by providing physical support and traction, countering weakness or unsteadiness. Walking unassisted heightens danger, especially without strength or balance. A dark room obscures hazards, increasing falls rather than preventing them rest doesn't trump safety. Placing items out of reach forces risky stretching or movement. Nurses implement these environmental aids to create a secure space, empowering safe mobility and minimizing injury, a critical aspect of care for vulnerable patients.

Correct Answer: B

Rationale: Monitoring oxygen saturation regularly prevents complications in oxygen therapy by ensuring levels stay within a safe range (e.g., 92-98% for most), avoiding hypoxia or hyperoxia. High flow rates without monitoring risk toxicity, especially in COPD patients. A tight mask causes discomfort and skin breakdown, not prevention. Limiting fluids is unrelated hydration supports recovery. Nurses use pulse oximetry to adjust delivery, balancing oxygenation with safety, and watch for signs like confusion or cyanosis, making this a proactive, essential step in respiratory care.
