The nurse is doing a neurologic assessment on a 2-month-old infant after a car accident. Moro, tonic neck, and withdrawal reflexes are present. The nurse should recognize that these reflexes are:
Symptomatic of decorticate posturing
Symptomatic of decerebrate posturing
Indicators of severe brain damage
Normal Findings
The Correct Answer is D
Reflexes play a crucial role in evaluating the neurological status of infants.
Moro reflex: Also known as the startle reflex, the Moro reflex is a normal response in infants. It occurs when an infant is startled by a sudden noise or movement. The baby responds by extending their arms and legs, followed by a quick contraction. This reflex usually disappears around 4-6 months of age.
Tonic neck reflex (fencer's reflex): This reflex involves turning an infant's head to one side, causing the arm on that side to extend and the opposite arm to flex. It's a normal reflex that typically disappears around 4-6 months of age.
Withdrawal reflex: The withdrawal reflex is a normal response to a stimulus, such as touching a baby's foot with a cold object. The baby will pull their leg away in response to the stimulus.
Symptomatic of decorticate or decerebrate posturing (options A and B):
Decorticate and decerebrate posturing are abnormal postures seen in individuals with severe brain damage or injury. Decorticate posturing involves the arms being flexed and held close to the body, while decerebrate posturing involves the arms being extended and the wrists being pronated. These reflexes are typically indicative of significant neurological dysfunction and are not expected in a 2-month-old infant after a car accident.
Indicators of severe brain damage (option C):
The reflexes described (Moro, tonic neck, and withdrawal reflexes) are not indicative of severe brain damage in a 2-month-old infant. These reflexes are normal for an infant of this age and are part of their typical neurological development.
Normal findings (option D):
The reflexes described are normal findings in a 2-month-old infant and are expected as part of their developmental milestones.

Related Questions
Correct Answer is D
Explanation
A. Assess the bowel sounds:
Bowel sounds are not directly related to the assessment of ascites. Bowel sounds are more relevant in assessing gastrointestinal function and peristalsis. While bowel changes could potentially be a sign of complications, monitoring abdominal girth is more specific to tracking ascites.
B. Frequently ambulate child:
While ambulation is important for overall health, it's not a direct assessment method for monitoring ascites. Ambulating a child might have benefits, but it won't provide specific information about the presence or progression of ascites.
C. Weigh child weekly:
Weekly weighing can provide some information about overall fluid balance, but it might not be as sensitive as measuring abdominal girth when it comes to detecting changes in ascites. Additionally, monitoring weight alone might not give insight into the distribution of fluid in the abdominal cavity.
D. Monitor and measure the abdominal girth.
Explanation: The presence of ascites (accumulation of fluid in the abdominal cavity) in a child with nephrotic syndrome could indicate worsening kidney function and fluid balance. Monitoring and measuring the abdominal girth is a reliable way to assess changes in the amount of fluid accumulation over time. An increase in abdominal girth could suggest a worsening condition.
Correct Answer is D
Explanation
A) Places the infant in a side-lying position:
Positioning is important in the care of an infant with myelomeningocele. The infant is usually placed in a prone (on the abdomen) position to prevent pressure on the sac and protect the neural tissue. Placing the infant in a side-lying position may not provide the needed protection.
B) Maintains a dry dressing over the sac:
The sac should be kept moist with a sterile, non-adherent dressing moistened with saline to prevent drying and cracking, which could lead to infection.
C) Performs range of motion on the infant's hips:
Infants with myelomeningocele often have flaccid paralysis below the lesion, and excessive manipulation of the lower limbs could cause injury.
D) Takes an axillary temperature:
Rectal temperatures should never be taken, as they can cause mucosal damage or irritate the exposed spinal cord, leading to complications like meningitis. The axillary route is the safest method for temperature assessment.
