Correct Answer: A

Rationale: The correct answer is to eat more food when planning to exercise more than usual. Increased physical activity requires more energy, so additional food intake is necessary to compensate for the increased energy expenditure. This helps maintain blood sugar levels within the target range. Choice B is incorrect because the mode of insulin administration does not change based on physical activity; the type and dose of insulin remain the same unless adjusted by a healthcare provider. Choice C is incorrect because insulin timing should not be adjusted solely based on anticipated exercise; consistent timing of insulin doses is crucial for stable blood sugar control. Choice D is incorrect because consuming foods with sugar may lead to unstable blood sugar levels and is not the recommended way to compensate for extra exercise, as it can result in sudden spikes and drops in blood glucose levels, affecting overall diabetes management.

Correct Answer: B

Rationale: The short urethra in young girls predisposes them to urinary tract infections. In young girls, the proximity of the urethra to the anus and the shorter urethra compared to boys make it easier for bacteria to travel up the urinary tract, increasing the risk of infection. Increased fluid intake and frequent emptying of the bladder are actually helpful in preventing urinary tract infections by flushing out bacteria. Prostatic secretions in males are not a factor in predisposing the urinary tract to infection in children.

Correct Answer: A

Rationale: Preventing shivering is crucial in this situation as it can increase the body temperature and counteract the effects of antipyretic measures aimed at reducing the fever. Shivering generates heat, potentially worsening the fever. Restricting oral fluids (Choice B) is not appropriate as fluid intake is important to prevent dehydration, especially in a child who has been vomiting. Measuring output hourly (Choice C) and taking vital signs hourly (Choice D) are important nursing actions but not as critical as preventing shivering in this scenario. Therefore, the most important nursing action is to prevent shivering to aid in fever reduction and management.

Correct Answer: A

Rationale: Right lower quadrant pain is a characteristic clinical manifestation of appendicitis. The appendix is typically located in the right lower quadrant of the abdomen, so pain in this area is a common symptom. Left lower quadrant pain (Choice B) is less likely in cases of appendicitis. Rebound tenderness (Choice C) is a sign of peritonitis, not specific to appendicitis. Epigastric pain (Choice D) is more indicative of upper gastrointestinal issues rather than appendicitis.

Correct Answer: A

Rationale: Monitoring liver function tests regularly is crucial when a child with JIA is on methotrexate due to the potential hepatotoxicity associated with this medication. Methotrexate can lead to liver damage, hence monitoring helps in early detection and intervention. Encouraging regular exercise (Choice B) is generally good for children with JIA to maintain joint mobility and muscle strength, but it is not directly related to methotrexate therapy. Providing high-calorie snacks (Choice C) is not a priority consideration for a child on methotrexate. Encouraging frequent handwashing (Choice D) is important for infection control, but it is not specifically associated with methotrexate therapy in a child with JIA.
