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 A
Explanation
A. Spina bifida.
Explanation: Correct Choice. Spina bifida is a neural tube defect (NTD) that occurs during early fetal development when the neural tube doesn't close completely. It can result in various degrees of spinal cord and nerve damage. This is a suitable example to include when teaching about neural tube defects.
B. Hydrocephalus.
Explanation: Hydrocephalus is not a neural tube defect itself. It's a condition characterized by the accumulation of cerebrospinal fluid in the brain, leading to increased intracranial pressure. It can be caused by various factors, but it's not directly related to neural tube development.
C. Cerebral palsy.
Explanation: Cerebral palsy is a group of motor disorders caused by damage to the developing brain, usually before birth. It is not a neural tube defect. Instead, it's related to brain injury or abnormal development.
D. Muscular dystrophy.
Explanation: Muscular dystrophy is a group of genetic disorders characterized by progressive muscle weakness and degeneration. It's not related to neural tube defects. Muscular dystrophy affects muscle tissue, while neural tube defects involve improper development of the neural tube.
Correct Answer is ["C","D","E"]
Explanation
A) Place a tongue depressor in the client's mouth:
Incorrect. Placing a tongue depressor in the client's mouth is not recommended during a seizure. Doing so can lead to injury, as the child may bite down on the depressor and cause harm to their teeth or mouth.
B) Restrain the client:
Incorrect. Restraining a person during a seizure can be extremely dangerous. It can lead to physical harm to both the person experiencing the seizure and the person trying to restrain them. Restraining can increase the risk of fractures, dislocations, and other injuries.
C) Assess the client's airway patency:
Correct. Assessing the client's airway patency is essential during a seizure. The nurse should ensure that the child's airway is clear and open to maintain proper breathing. This involves observing for any obstruction or difficulty in breathing and taking appropriate measures to keep the airway open.
D) Remove objects from the client's bed:
Correct. Removing objects from the client's bed is a necessary action to prevent injury during a seizure. Objects on the bed can pose a risk of harm to the child if they were to strike them during the seizure. Creating a safe environment by removing potential hazards is important.
E) Place the client in a side-lying position:
Correct. Placing the client in a side-lying position is recommended during a seizure. This position helps prevent aspiration and maintains a clear airway. It also reduces the risk of choking and allows any fluids to drain from the mouth, minimizing the risk of choking.
In summary:
Choice A is incorrect because placing a tongue depressor can cause injury.
Choice B is incorrect because restraining can lead to harm.
Choice C is correct because assessing the airway ensures proper breathing.
Choice D is correct because removing objects reduces the risk of injury.
Choice E is correct because placing the client in a side-lying position helps maintain a clear airway and prevents aspiration.
