Sodium Lab Value - correct answer ✔135-145 mEq/L
Potassium Lab Value - correct answer ✔3.5-5.0 mEq/L
Magnesium Lab Value - correct answer ✔1.3-2.3 mEq/L
Calcium Lab Value - correct answer ✔8.6-10.2 mg/dL
Phosphate Lab Value - correct answer ✔2.5-4.5 mg/dL
Chloride Lab Value - correct answer ✔97-107 mEq/L
Bicarbonate (HCO3) Lab Value - correct answer ✔22-26 mEq/L
Normal blood pH - correct answer ✔7.35-7.45
PaCO2 Normal Range - correct answer ✔35-45 mm Hg
Albumin Normal Range - correct answer ✔3.4-5.4 g/dL
, Fluid Volume Deficit (hypovolemia) - correct answer ✔s/sx: tachycardia, slow skin turgor,
pinched/drawn facial expression
Causes: V/D, low water intake, burns, liver failure, crush injury, CHF, hyponatremia
*old, young, ill at highest risk
*15% weight loss due to fluid deficiency = LIFE THREATENING
Fluid Volume Excess (hypervolemia) - correct answer ✔Excess retention of H2O & Na+ in ECF+
-can be hypervolemia (intravascular) or edema (interstitial) both = weight gain
Interstitial - correct answer ✔space between cells
symptoms of hypervolemia - correct answer ✔tachypnea, neck vein distention, moist crackles
causes of hypervolemia - correct answer ✔excess H2O and Na+ intake, organ dysfunction of kidney or
heart
What is the best indicator of fluid balance? - correct answer ✔weight
Sodium function - correct answer ✔Swells to regulate BP, BV, and pH (regulates ECF volume), muscle
contraction, and nerve impulse conduction
*MOST ABUNDANT ELECTROLYTE/CATION in ECF
Examples of nonverbal communication - correct answer ✔facial expression, eye contact, space, time,
boundaries, body movements
What are the three phases of interviewing? - correct answer ✔Orientation phase, working phase,
termination phase
