_____________ the ability or tendency to maintain internal stability in spite of external changes.
Explanation
Homeostasis refers to the ability or tendency of an organism to maintain internal stability despite external changes. It is a vital process that allows the body to regulate various physiological variables, such as temperature, blood pressure, and pH levels, within a narrow range. This balance is essential for the proper functioning of cells, tissues, and organs. Homeostasis is achieved through feedback mechanisms that sense changes in the internal environment and initiate appropriate responses to restore equilibrium. It ensures that the body can adapt and respond to external stimuli while keeping its internal conditions relatively constant.Rate this question:

Which statement best describes why infants are at greater risk for dehydration than older children?
- A.
Infants have an increased ability to concentrate urine.
- B.
Infants have a greater volume of intracellular fluid.
- C.
Infants have a smaller body surface area.
- D.
Infants have an increased extracellular fluid volume.
Correct Answer
D. Infants have an increased extracellular fluid volume.Explanation
Feedback Because the kidneys are immature in early infancy, there is a decreased ability to concentrate the urine. Infants have a larger proportion of fluid in the extracellular space. Infants have proportionately greater body surface area in relation to body mass, which creates the potential for greater fluid loss through the skin and gastrointestinal tract. Answer* The larger ratio of extracellular fluid to intracellular fluid predisposes the infant to dehydration.Rate this question:

What is the most important factor in determining the rate of fluid replacement in the dehydrated child?
- A.
The child's weight
- B.
The type of dehydration
- C.
Urine output
- D.
Serum potassium level
Correct Answer
B. The type of dehydrationExplanation
Feedback
The child's weight determines the amount of fluid needed, not the rate of fluid
replacement. One milliliter of body fluid is equal to 1 g of body weight; therefore
a loss of 1 kg (2.2 lb) is equal to 1 L of fluid.
answer* Isonamtremic and hyponatremic dehydration resuscitation involves fluid
replacement over 24 hours. Hypernatremic dehydration involves a slower
replacement rate to prevent a sudden decrease in the sodium level.
Urine output is not a consideration for determining the rate of administration of
replacement fluids.
Potassium level is not as significant in determining the rate of fluid replacement
as the type of dehydration.Rate this question:
