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.

Correct Answer is A
Explanation
A. "My son might complain of feeling shaky when he has a low blood glucose level."
Explanation: Correct Choice. Shaking or feeling shaky is a common symptom of low blood glucose levels, also known as hypoglycemia. When blood sugar drops too low, the body releases adrenaline, causing shaking or trembling. This response is indicative of an understanding of hypoglycemia symptoms.
B. "My son might have nausea and vomiting with hypoglycemia."
Explanation: Nausea and vomiting are not typical symptoms of hypoglycemia (low blood sugar). They are more commonly associated with hyperglycemia (high blood sugar) or other conditions. This statement is not accurate in the context of hypoglycemia.
C. "Sweating can occur with hyperglycemia."
Explanation: Sweating is more commonly associated with hypoglycemia (low blood sugar) rather than hyperglycemia (high blood sugar). When blood sugar levels drop too low, the body can respond with sweating as part of the adrenaline release. Sweating is not a typical symptom of hyperglycemia.
D. "The onset of low blood glucose usually occurs slowly."
Explanation: The onset of low blood glucose (hypoglycemia) can vary. It can occur suddenly, especially if the individual takes too much insulin or diabetes medication, leading to a rapid drop in blood sugar. The correct understanding is that the onset of low blood glucose can be rapid and not always slow.
Correct Answer is B
Explanation
A) Document intake and output:
Documenting intake and output is an important nursing task, but it is not the top priority in a suspected case of bacterial meningitis. Timely administration of antibiotics to treat the infection takes precedence over documentation of intake and output.
B) Administer antibiotics when available.
Explanation:
Bacterial meningitis is a serious and potentially life-threatening infection of the membranes covering the brain and spinal cord. Rapid administration of antibiotics is crucial to effectively treat the infection and prevent its spread. Delay in antibiotic administration can lead to worsening symptoms and complications. Therefore, getting the appropriate antibiotics to the child as soon as they are available is the nurse's priority.
C) Reduce environmental stimuli:
Reducing environmental stimuli can be helpful in managing symptoms and providing comfort to the child with meningitis, but it is not the priority action. The immediate concern in a suspected case of bacterial meningitis is to treat the infection.
D) Maintain seizure precaution:
While maintaining seizure precautions is important, especially if the child has a history of seizures, it is not the top priority in a suspected case of bacterial meningitis. Administering antibiotics to treat the infection and prevent its progression is the primary concern.
