Symptoms = marked water retention and dilutional hyponantremia
Treatment = fluid restriction (mild cases), diuretics such as mannitol and furosemide

Question 4

Isotonic Fluid Volume Deficit (Dehydration)

Answer 4

A decrease in the ECF including the circulating blood volume
There are proportionate losses in sodium and water
A loss in body fluids and is accompanied by a decrease in fluid intake
Loss of body fluids due to loss of GI fluids, polyuria, or sweating due to fever and exercise
Symptoms = thirst, loss of body weigh, signs of water conservation by the kidney, impaired temperature regulation, signs of reduced interstitial vascular volume
Treatment = fluid replacement, usually isotonic electrolyte solutions are used for fluid replacement

Question 5

Isotonic Fluid Volume Excess (Water intoxication)

Question 11

Metabolic Acidosis

Answer 11

Decreased plasm HC03- concentration along with a decrease in pH

The body compensates for the decrease in pH by increasing the respiratory rate in an effort to decrease PC02 and H2C03 levels

Question 21

Diabetes Ketoacidosis (DKA)

Answer 21

Most commonly occurs in a person with Type 1 diabetes, whom the lack of insulin leads to mobilization of fatty acids from adipose tissue because of the unsuppressed adipose cell lipase activity that breaks down triglycerides into fatty acids and glycerol.

The increase in fatty acids levels leads to ketone production by the liver

Causes= stress increases the release of gluconeogenic hormones, infection, pregnancy, or extreme anxiety , omission or inadequate use of insulin

Symptoms = polyuria, polydipsia, nausea, vomiting, and marked fatigue, abdominal pain, and tenderness, fruity smelling breath, hypotension and tachycardia, decreased blood volume

The heart rate increases as the body compensates for a decrease in blood volume and the rate and depth of respirations increase to prevent further decreases in pH
