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.

Pilonidal dimpling with the presence of an abnormal tuft of hair in or near the dimple

Explanation:

Spina bifida is a congenital condition where there is incomplete closing of the backbone and membranes around the spinal cord during early development in the womb. Pilonidal dimpling with the presence of an abnormal tuft of hair in or near the dimple is a specific sign of spina bifida. This condition is called "sacral dimple," and it can indicate an underlying issue with the spinal cord and nerves. An abnormal tuft of hair in or near the dimple suggests a neural tube defect, which is characteristic of spina bifida.

Why the other choices are incorrect:

A. complete paralysis:

Complete paralysis is a severe neurological symptom but it is not specific to spina bifida. It can occur due to various other conditions as well, such as spinal cord injuries, infections, and neurological disorders. It's not a characteristic sign of spina bifida.

B. Petechiae:

Petechiae are small, red or purple spots on the skin that are caused by bleeding under the skin. They are usually associated with bleeding disorders, infections, or other medical conditions. Petechiae are not a characteristic sign of spina bifida.

C. Abnormal Vital Signs:

While spina bifida can potentially lead to neurological complications that might influence vital signs, the presence of abnormal vital signs is a non-specific symptom. Abnormal vital signs could be caused by a wide range of medical conditions, and they are not directly indicative of spina bifida.
