A nurse is assessing a toddler for developmental milestones.
At what age should a child be able to build a tower of six cubes?

Choice A rationale

Type 2 diabetes in pediatric patients can sometimes be managed effectively through lifestyle modifications alone, particularly in the early stages. These changes include dietary adjustments to reduce sugar and processed foods, increased physical activity to improve insulin sensitivity, and weight management.

Choice B rationale

Insulin resistance is a key pathophysiological feature of type 2 diabetes. In this condition, the body's cells do not respond effectively to insulin, leading to elevated blood glucose levels as glucose cannot enter the cells for energy. The pancreas initially produces more insulin to compensate, but eventually, it may not be able to keep up.

Choice C rationale

Type 1 diabetes is more commonly diagnosed in younger children and adolescents, often presenting with acute symptoms. It results from the autoimmune destruction of insulin-producing beta cells in the pancreas, leading to an absolute deficiency of insulin.

Choice D rationale

Type 1 diabetes is an autoimmune disease where the body's immune system mistakenly attacks and destroys the pancreatic beta cells that produce insulin. This autoimmune process is often triggered by genetic predisposition and environmental factors but is not directly caused by lifestyle.

Choice E rationale

Obesity is a significant risk factor for the development of type 2 diabetes due to its association with increased insulin resistance. While individuals with type 1 diabetes can also be obese, obesity is not the primary cause of type 1 diabetes.

Choice F rationale

Type 1 diabetes cannot be cured with lifestyle changes alone because it involves the permanent destruction of insulin-producing cells. Individuals with type 1 diabetes require lifelong insulin therapy to survive.

Choice G rationale

Type 1 diabetes cannot be prevented with healthy eating or other lifestyle modifications because it is an autoimmune condition. The onset is not directly linked to dietary habits or physical activity levels.

Choice H rationale

Type 2 diabetes is less common in infants and toddlers and is more frequently diagnosed in older children, adolescents, and adults, often associated with factors like obesity, family history, and sedentary lifestyle.

Choice A rationale

Projectile vomiting and confusion are highly concerning symptoms in a child with suspected Reye syndrome. Projectile vomiting indicates increased intracranial pressure, and confusion reflects encephalopathy, both of which are hallmark signs of the severe neurological involvement in Reye syndrome.

Choice B rationale

Fever and cough are common symptoms of many childhood illnesses, particularly respiratory infections. While Reye syndrome can sometimes follow a viral illness, fever and cough alone are not specific indicators of this condition.

Choice C rationale

Mild headache is a relatively non-specific symptom and can be associated with various conditions. While headache may occur in the early stages of some illnesses, it is not the most concerning symptom suggestive of Reye syndrome.

Choice D rationale

Muscle aches can be associated with viral infections, which sometimes precede Reye syndrome. However, muscle aches alone are not as concerning as the neurological symptoms of confusion and increased intracranial pressure indicated by projectile vomiting.
