AND CORRECT ANSWERS
◉What is the corrected osmolality of 0.9% NaCl? Answer: 286
mOsm/kg, which is within the normal range and is considered
isotonic.
◉What is the osmolality of 3% NaCl? Answer: 953 mOsm/kg.
◉What is the osmolality of 0.45% NaCl? Answer: 143 mOsm/kg.
◉What is the osmolality of dextrose 5%? Answer: 252 mOsm/kg.
◉What is the estimated water content in an adult male? Answer:
Approximately 60% of body weight.
◉How does dehydration affect plasma sodium levels? Answer:
Plasma sodium levels often rise due to water depletion.
, ◉What formula is used to estimate volume deficit from sodium
concentration? Answer: Volume deficit = [Na+]obs / (percentage of
total body water).
◉How much total body water has a 70 kg male lost if his plasma
sodium is 150 mEq/L? Answer: He has lost 3 L of total body water.
◉What is the normal range of sodium concentration? Answer: 135-
145 mEq/L.
◉What is the formula for calculating sodium deficit in
hyponatremia? Answer: Sodium deficit = [Na+]desired -
[Na+]actual.
◉How much normal saline is needed to replace a sodium deficit of
154 mEq? Answer: Approximately 5 L of normal saline.
◉What is the fractional excretion of sodium (FENa)? Answer: The
percentage of filtered sodium that is excreted in urine.
◉What FENa value indicates prerenal azotemia? Answer: FENa <
1%.
