Diagnostic tests for fluid and electrolyte balance

Question 1

This test gives direct information on extracellular levels and indirect information on intracellular levels of the electrolytes.

Answer 1

Levels of serum electrolytes- sodium, potassium, magnesium, calcium, chloride, and phosphate

Question 2

This lab test indicates renal function

Answer 2

Blood urea nitrogen BUN, creatine

Question 3

This lab test gives information on hydration status, useful in managing fluid requirements

Answer 3

Serum osmolarity/osmolality

Question 4

This lab test indicates oxygen carrying capacity, fluid volume deficit/excess.

Answer 4

Red blood cells, hemoglobin, hematocrit

Question 5

This lab test indicates colloid oncotic pressure capability

Answer 5

Levels of serum albumin

Question 6

This lab test gives information about the hydrogen ion concentration in the urine. Increases or decreases based on acid-base balance.

Answer 6

Urinalysis pH

Question 7

This test shows increase when fluid volume is concentrated, and low when there is a fluid volume excess.

Answer 7

Urinalysis specific gravity

Question 8

This test reflects solute concentration of the urine. urine osmolarity/osmolality is increased in fluid volume deficit and decreased in fluid volume excess.

Answer 8

urinalysis
urine osmolarity/osmolality

Question 9

This is a common diagnostic test that diagnosis UTIs and helpful in detecting diseases and disorders unrelated to renal system. Reagent strip is used

Answer 9

Urinalysis
