Which sign is the nurse most likely to assess in a child with hypoglycaemia?

Precocious puberty is defined as the onset of puberty before the age of 8 in girls and before the age of 9 in boys. However, it is important to note that the exact age at which puberty is considered precocious can vary slightly based on different guidelines and individual variations.

Boys: 11 years; girls: 9 years in (option A) is incorrect because it, is close to the general age range, but it is slightly earlier than what is commonly considered precocious puberty.

Boys: 10 years; girls: 9 1/2 years in (option C) is incorrect because it, is also close to the general age range, but it is not as commonly recognized as the age for precocious puberty.

Boys: 9 years; girls: 8 years in (option D) is incorrect because it, is significantly earlier than the usual age for precocious puberty. Puberty occurring at this age would be considered very early and may warrant further evaluation.

Hypoglycaemia is characterized by low blood sugar levels. In children, symptoms of hypoglycaemia can vary, but irritability is a common sign. Other signs and symptoms of hypoglycaemia in children may include sweating, trembling, pale skin, hunger, weakness, confusion, and dizziness.

Normal sensorium and serum glucose greater than 160 mg/dL in (Option A) is incorrect because a normal sensorium (normal level of consciousness) and a serum glucose level greater than 160 mg/dL would not be indicative of hypoglycaemia.

Urine positive for ketones and serum glucose greater than 300 mg/dL in (Option B) is incorrect because it describes characteristics of hyperglycaemia (high blood sugar levels) rather than hypoglycaemia. Positive urine ketones and a serum glucose level greater than 300 mg/dL are commonly seen in diabetic ketoacidosis, a complication of high blood sugar levels in diabetes.

Increased urination and serum glucose less than 120 mg/dL in (Option D) is incorrect because it describes increased urination and a serum glucose level less than 120 mg/dL. While a serum glucose level less than 120 mg/dL could indicate hypoglycaemia, increased urination is not a typical sign of hypoglycaemia. Increased urination may be seen in conditions such as diabetes mellitus when blood sugar levels are consistently high.
