Correct Answer: A

Rationale: The correct answer is A. Reading stories to the child about famous athletes would be the most successful guidance for a child with a 'slow-to-warm-up' temperament. This approach allows for a less active and more acceptable way of engaging with the child, aligning better with the child's temperament. Choices B, C, and D involve more active and potentially overwhelming activities for a child with such a temperament, which may not be as effective in stimulating and engaging the child.

Correct Answer: D

Rationale: Preparing a toddler for a CT scan involves providing a simple explanation of the procedure to reduce anxiety and help the child understand what will happen. This approach helps establish trust and cooperation, making the experience less frightening for the child. Shaving the head, starting an IV infusion, or administering a sedative are not typically part of the preparation for a CT scan in a toddler and may not be necessary or appropriate in this scenario.

Correct Answer: B

Rationale: The correct answer is B: Obesity. Children with Down syndrome are at a higher risk of obesity due to various factors such as lower metabolic rate, hormonal imbalances, and reduced physical activity levels. Addressing healthy eating habits early can help prevent obesity in these children. Choice A (Rickets) is incorrect because rickets is primarily associated with vitamin D deficiency and is not a common nutritional problem in children with Down syndrome. Choice C (Anemia) is incorrect as anemia may not be a common nutritional problem specific to children with Down syndrome. Choice D (Rumination) is incorrect as rumination is a behavioral disorder characterized by repeated regurgitation of food and is not a common nutritional problem associated with Down syndrome.

Correct Answer: B

Rationale: The correct answer is B: Signs of child abuse. When a nurse observes large welts and scars on a child, it raises concern for possible child abuse. It is crucial for the nurse to assess further for signs of abuse, document findings, and report appropriately to protect the child. Choice A, history of an injury, is not specific to potential abuse and may not provide insight into the current situation. Choice C, presence of food allergies, is not directly related to the observed welts and scars. Choice D, recent recovery from chickenpox, is also unrelated to the signs of abuse and does not impact the immediate assessment of the child's safety.

Correct Answer: C

Rationale: In a child diagnosed with acute glomerulonephritis, monitoring urine output is a crucial assessment. Acute glomerulonephritis affects the kidneys, leading to decreased urine output due to impaired kidney function. Monitoring urine output helps assess renal perfusion, fluid status, and kidney function. This assessment is essential in determining the effectiveness of treatment and identifying complications. Monitoring blood glucose levels (Choice A) is not directly related to acute glomerulonephritis. Respiratory rate (Choice B) may be important in other conditions but is not a key assessment for acute glomerulonephritis. Monitoring for signs of infection (Choice D) is important in general, but it is not specific to the primary issue of impaired kidney function in acute glomerulonephritis.
