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. You do not need to lose consciousness to suffer a concussion.
This statement is true. Concussion is a type of traumatic brain injury (TBI) that can occur without loss of consciousness. Many concussions happen without the person losing consciousness at all.
B. You will suffer permanent brain damage.
This statement is not necessarily true. While some concussions can lead to lasting effects, not all cases result in permanent brain damage. The severity and long-term effects of a concussion can vary widely.
C. We encourage fluids after a concussion.
This statement is true. Adequate hydration is important after a concussion. Staying hydrated can help support the brain's recovery process.
D. Bleeding always occurs with a concussion.
This statement is not true. Concussion is defined by the disruption of normal brain function due to a blow or jolt to the head or body, and bleeding is not always a necessary component of a concussion. However, more severe head injuries could involve bleeding and would not be classified as just a concussion.
Correct Answer is ["5.625"]
Explanation
To calculate the dose of amoxicillin for the toddler:
Step 1: Convert the toddler's weight from pounds to kilograms.
33 lb ÷ 2.2 (lb to kg conversion factor) = approximately 15 kg
Step 2: Calculate the total daily dose of amoxicillin.
Dose = 30 mg/kg/day × 15 kg = 450 mg/day
Step 3: Divide the total daily dose into equal doses every 12 hours.
450 mg/day ÷ 2 doses = 225 mg/dose
Step 4: Calculate the amount of amoxicillin suspension needed for each dose.
The available concentration is 200 mg/5 mL, so for 225 mg, you would use the proportion:
225 mg : 200 mg = x mL : 5 mL
Cross-multiplying: x = (225 mg × 5 mL) / 200 mg ≈ 5.625 mL
Therefore, the nurse should administer approximately 5.625 mL of amoxicillin suspension for each dose.
