Infants Exam Newest 2026 Questions and
Correct Detailed Answers Already Graded A+
What is the major constituent of body tissues? - CORRECT ANSWER-Water
What does Total Body Water (TBW) include? - CORRECT ANSWER-All water
within the body, including intracellular and extracellular water, plus water in the
GI and urinary tracts.
What is the significance of third spacing in fluid balance? - CORRECT ANSWER-
It refers to the pooling of body fluids in a body space, affecting fluid distribution.
What physiological consequences can arise from alterations in body fluid volume?
- CORRECT ANSWER-Severely damaging physiologic consequences can occur.
What happens to metabolism when there is an increase? - CORRECT ANSWER-
Greater heat production occurs, leading to insensible fluid loss and an increased
need for water for excretion.
, What is BMR and why is it higher in infants? - CORRECT ANSWER-Basal
Metabolic Rate (BMR) is higher in infants to support cellular and tissue growth.
What factors affect fluid loss in infants? - CORRECT ANSWER-Kidney function,
fluid requirements, hydration status, size, environmental factors, and underlying
disease.
Why are infants' kidneys functionally immature at birth? - CORRECT ANSWER-
They are inefficient in excreting waste products, concentrating or diluting urine,
conserving or excreting sodium, and acidifying urine.
What can lead to dehydration in infants? - CORRECT ANSWER-Concentrated
formulas can lead to dehydration, while excessive free water or dilute formula
can cause overhydration.
What are the symptoms of short-term dehydration? - CORRECT ANSWER-Low
blood pressure, increased heart rate, and dry mucous membranes.
What percentage of total body weight does TBW range from in late adolescence
to term newborn? - CORRECT ANSWER-From 45% in late adolescence to 75%
in term newborns.
