NSG 122 Fundamentals Exam 5 Questions with
Verified Correct Answers
Sensible Fluid Loss
can be measured and include fluid lost during urination, defecation, and wounds.
Insensible Fluid Loss
cannot be measured or seen and include fluid lost from evaporation through the skin and as
water vapor from the lungs during respiration
3 Body Regulation of Fluid Intake
1. Hypothalamus (controls thirst)
2. Kidneys (control Na retention & urine output)
3. Metabolic Oxidation (fluid from food breakdown)
Intracellular Fluid
Fluid within cells (ICF)
Extracellular Fluid
Fluid outside the cells (ECF)
Causes of Third Space Fluid Shift
Burns & Sepsis
Third Space Fluid Shift Definition
1. Distributional shift of body fluids into the transcellular compartment, such as the pleural,
peritoneal (ascites), or pericardial areas; joint cavities; the bowel
2. Excess accumulation of fluid in the interstitial space.
, 3. Deficit of fluid in ECF
4. Fluid trapped in the body
Normal pH
7.35-7.45
Acidosis
is the condition characterized by an excess of H ions or loss of base ions (bicarbonate) in
ECF in which the pH falls below 7.35
Alkalosis
occurs when there is a lack of H ions or a gain of base (bicarbonate) and the pH exceeds 7.45.
HCO3- Normal Range
Acid Range & Basic Range
22-26
Below 22 Acid
Above 26 Alkalosis
PaCO2 Normal Range
Acid Range & Basic Range
35-45
Above 45 Acid
Below 35 Base
Respiratory Acidosis
Is a primary excess of carbonic acid in the ECF. It is produced by inadequate excretion of
CO2 with inadequate ventilation, resulting in elevated plasma CO2 and increased levels of
