Question 1 of 5
When a 2-week-old infant is seen for irritability, poor appetite, and rapid head growth with observable distended scalp veins, the nurse recognizes these signs as indicative of which disorder?
Correct Answer: C
Rationale: The correct answer is C: Hydrocephalus. In a 2-week-old infant presenting with irritability, poor appetite, rapid head growth, and distended scalp veins, these signs are classic indicators of hydrocephalus. Rapid head growth is a key feature of hydrocephalus due to the accumulation of cerebrospinal fluid in the brain. The distended scalp veins are a result of increased intracranial pressure. Irritability and poor appetite can be attributed to the discomfort and pressure caused by the condition. Cerebral palsy (
A) is a motor disorder, not typically associated with rapid head growth. Syndrome of inappropriate antidiuretic hormone (SIADH) (
B) involves abnormal water balance regulation, not head growth. Reye's syndrome (
D) is characterized by acute encephalopathy and liver dysfunction, unrelated to head growth or scalp veins in this context.
