Which statement best describes why infants are at greater risk for dehydration than older children?
Infants have an increased ability to concentrate urine.
Infants have an increased extracellular flued volume
Infants have a greater volume of intracellular fluid.
Infants have a smaller body surface area.
The Correct Answer is B
The statement that best describes why infants are at greater risk for dehydration than older children is option B. Infants have an increased extracellular fluid volume compared to older children. This means that a larger proportion of their total body fluid is located outside the cells, in the extracellular compartment. This higher extracellular fluid volume makes infants more susceptible to fluid losses and dehydration if they experience inadequate fluid intake or increased fluid losses.
infants have an increased ability to concentrate urine in (option A), is incorrect. Infants have limited renal function and may have difficulty concentrating urine compared to older children and adults. This can contribute to a higher risk of dehydration in infants.
infants have a greater volume of intracellular fluid in (option C), is incorrect. The volume of intracellular fluid is not the primary factor contributing to the increased risk of dehydration in infants.
infants have a smaller body surface area in (option D) is incorrect because it, is not directly related to the increased risk of dehydration. Body surface area influences heat exchange and fluid loss through sweating but is not the main factor contributing to the higher risk of dehydration in infants.

Correct Answer is A
Explanation
A subdural hematoma is a type of intracranial bleeding that occurs between the dura mater (the
outermost layer of the meninges) and the skull. The dura mater is a tough membrane that covers
and protects the brain. When a subdural hematoma occurs, blood collects between the dura mater
and the skull, resulting in increased pressure on the brain.
Bleeding is generally arterial, and brain compression occurs rapidly in (Option B) is incorrect because
while bleeding in a subdural hematoma can be arterial, it can also be venous. The rate of bleeding
and brain compression can vary depending on the size and severity of the hematoma.
Bleeding occurs between the dura and the cerebrum in (Option C) is incorrect because the bleeding
in a subdural hematoma does not occur between the dura and the cerebrum (the largest part of the
brain). It specifically occurs between the dura and the skull.
The hematoma commonly occurs in the pretemporal region in (Option D) is incorrect because the
location of a subdural hematoma can vary. While pretemporal region is a possible location, subdural
hematomas can occur in different areas of the brain, depending on the site of injury.
Correct Answer is A
Explanation
During adolescence, there is a period of rapid physical growth and development. This growth spurt requires additional energy and resources from the body, which can lead to increased fatigue and a heightened need for sleep. The body utilizes sleep as a time for rest, repair, and growth, and during this growth phase, the demand for restorative sleep tends to increase.
decreased activity in (option B) is incorrect because it, does not necessarily contribute to an increased need for sleep. While decreased activity may result in less fatigue and the perception of needing less sleep, it is not a predisposing factor for feeling an increased need for sleep.
typical lack of ambition in (option C) is incorrect because it, is not associated with an increased need for sleep. Lack of ambition refers to a lack of motivation or drive, which is not directly related to the physiological need for sleep.
an inadequate diet in (option D) is incorrect because it, can affect overall health and well- being, but it is not specifically associated with an increased need for sleep. However, a well- balanced and nutritious diet can support healthy growth and development, including adequate sleep patterns.
