What do we include as part of our concussion/head injury prevention teaching to children and parents:

Fluid Requirement (mL/24 hours) = Weight (kg) × Fluid Requirement (mL/kg)

Given that the child weighs 70.4 pounds, we first need to convert this weight to kilograms (1 lb = 0.453592 kg):

Weight in kg = 70.4 lb × 0.453592 kg/lb ≈ 31.89 kg

Now, let's calculate the fluid requirement using the given choices:

A) 1740:

Fluid Requirement = 31.89 kg × 55 mL/kg = 1753.95 mL

B) 134056:

This number is significantly larger than any reasonable fluid requirement and is likely an error.

C) 2:

This value is far too low to represent the fluid requirements of a child.

D) 12:

This value is also too low to represent the fluid requirements of a child.

So, the correct answer is A) 1740 mL. The child's estimated daily fluid requirement would be around 1740 mL in a 24-hour period, based on a weight of 70.4 pounds.

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.
