Correct Answer: A

Rationale: Short stature in growing children can result from anterior pituitary gland hypofunction, which leads to growth hormone deficiency. The anterior pituitary gland plays a crucial role in stimulating the release of growth hormone, and when it is underactive (hypofunction), insufficient growth hormone is produced, resulting in short stature and slow growth rates.

Correct Answer: B

Rationale: In the management of diabetic ketoacidosis (DKA), the initial intravenous (IV) fluid of choice is normal saline infusion. Normal saline helps to correct dehydration and electrolyte imbalances commonly seen in DKA patients. It does not contain glucose to prevent worsening hyperglycemia or ketoacidosis. NPH insulin infusion is not the initial treatment for DKA; it is typically used after fluid resuscitation. Potassium infusion may be required in DKA to address electrolyte imbalances, but normal saline is the priority for fluid resuscitation.

Correct Answer: C

Rationale: Encouraging the child to drink liquids is essential in managing ketones in urine. Increased fluid intake can help prevent dehydration and aid in flushing out ketones, which is crucial in managing diabetic ketoacidosis, a serious complication of uncontrolled diabetes.

Correct Answer: A

Rationale: The correct answer is 108.3mL. This amount is calculated based on the total daily fluid requirement, ensuring a consistent infusion rate over the hour.

Correct Answer: B

Rationale: The appropriate diagnosis for the symptoms described in Kanjaga, a 7-year-old child, is hypothyroidism. Hypothyroidism can lead to symptoms such as fatigue, slow heart rate, dry skin, slower growth, and delayed puberty in children.
