Which of these assessments is the priority for an infant who is diagnosed with Hirschsprung disease?

Total white blood cell count 7,000/mm.

Serum potassium 4.2 mEq/L.

Nonbilious vomiting.

Watery diarrhea.

Answer and Explanation

The Correct Answer is C

Choice A rationale:

While monitoring the total white blood cell count is important, it is not the priority assessment for a child with Hirschsprung disease. The disease primarily affects the gastrointestinal system.

Choice B rationale:

Serum potassium level within the normal range (4.2 mEq/L) is relevant, but it doesn't take precedence over assessing symptoms directly related to Hirschsprung disease.

Choice C rationale:

Nonbilious vomiting could indicate a bowel obstruction, a potential complication of Hirschsprung disease. Prompt assessment is necessary to prevent further complications.

Choice D rationale:

Watery diarrhea might occur in Hirschsprung disease, but it's not as urgent as addressing vomiting, which could indicate a more immediate problem like bowel obstruction.

Correct Answer is B

Explanation

Choice A rationale:

Neck vein distention might be seen in conditions affecting venous return to the heart, such as heart failure, but it's not a specific symptom of closed head injury.

Choice B rationale:

Fixed, dilated pupils are a classic sign of increased intracranial pressure. The pressure can compress the cranial nerves, leading to changes in pupillary size and reactivity.

Choice C rationale:

Shortness of breath is more related to respiratory issues and might not be directly linked to a closed head injury.

Choice D rationale:

Glycosuria, the presence of glucose in the urine, is not a primary symptom of closed head injury. It could be related to diabetes or other metabolic conditions.

A. "The improvement may indicate a misdiagnosis of insulin-dependent diabetes mellitus.". B. "The improvement is evidence of the creation of new insulin-producing cells in the pancreas.". C. "The improvement is a temporary response of the insulin-producing cells of the pancreas.". D. "The improvement is the beginning of a complete recovery for your child.".

Correct Answer is C

Explanation

Choice A rationale:

Misdiagnosis is unlikely since the glucose levels are improving, indicating a valid diagnosis.

Choice B rationale:

Insulin-producing cells don't regenerate in substantial amounts to normalize glucose levels within a month. This process takes longer.

Choice C rationale:

This choice correctly identifies the situation as a temporary improvement due to the remaining insulin-producing cells functioning better temporarily.

Choice D rationale:

Complete recovery is not likely in such a short time frame.
