NURS 265 Pediatrics Exam 1 Fluids & Electrolytes (Latest 2026
Update) 100% Verified Questions & Answers | Grade A+
Fluid volume deficit - CORRECT ANSWER --decrease in intravascular, interstitial &/or
intracellular fluid in the body
-common
-may exist alone or in combo with electrolyte or acid base imbalances
-dehydration- loss of fluid alone
-occurs slowly or rapidly
How infants and younger children - CORRECT ANSWER --differ from older children and adults:
--the are more vulnerable to alterations in fluid & electrolyte balance
--disturbances occur more often & quicker
--slower adjustments to these alterations
--greater fluid intake & output relative to their size
--length of small intestine - greater in infant (larger surface for absorption)
--more susceptible to infection
infants and young children - CORRECT ANSWER --extracellular fluid compartment is larger and
constitutes greater proportion of body weight
-infants have a high daily fluid requirement with little reserve. Kidneys are immature and
inefficient
-greater body surface area
-Higher basal metabolic rate (BMR)
factors that affect fluid and electrolyte - CORRECT ANSWER --age
- body size
, -gender
-environmental temperature
-lifestyle - diet exercise stress phototherapy
-pediatric specific examples
---water weight higher at birth
---women more body fat and less water then in men
-obese have more fat cells than water and lean has more water
dehydration - CORRECT ANSWER --common fluid imbalance in both infants and children
-total output >total intake
-a number of diseases may cause insensible losses
---respiratory and renal type diseases
---medications cause insensible loss
---diarrhea and vomiting -most common
---GI losses
types of dehydration - CORRECT ANSWER --isotonic
-hypotonic
-hypertonic
isotonic dehydration - CORRECT ANSWER --Primary form in children
-electrolyte and water deficits are equal (signs of hypovolemic shock)
-occurs from vomiting and diarrhea
hypotonic dehydration - CORRECT ANSWER --electrolyte deficits greater than water deficits
(ECF more concentrated -more severe symptoms)
