Questions and Answers

What is hypovolemia?

A decrease in the volume of blood in the body (correct)

A condition resulting from excessive fluid intake

A condition causing excessive perspiration

An increase in the volume of blood in the body

Which of the following can cause blood loss leading to hypovolemia?

Diarrhea and vomiting (correct)

Adequate fluid intake

Excessive perspiration

How does the body initially compensate for volume loss in hypovolemia?

By decreasing the heart rate

By dilating blood vessels in the periphery

By increasing the heart rate and the strength of heart contractions (correct)

By reducing the strength of heart contractions

Study Notes

Hypovolemia and Hypervolemia: Causes, Symptoms, and Treatment

Hypovolemia results in loss of color and less noticeable warmth in the skin, increased heart rate, and decreased blood pressure if not corrected
Symptoms of untreated hypovolemia include sweating, lightheadedness, confusion, fatigue, and decreased blood pressure
Internal bleeding, gastrointestinal bleeding, and shifting fluid out of the bloodstream can cause hypovolemia
Severe dehydration and even severe edema can lead to hypovolemia
There is no definitive blood test for hypovolemia; vital signs and history are important
Treatment for hypovolemia involves fluid replacement, addressing the underlying cause, and blood transfusion in severe cases
Hypervolemia, or fluid overload, results from an increase in total body sodium content and water
Causes of hypervolemia include congestive heart failure, kidney failure, liver failure, excessive sodium intake, hemodialysis, and peritoneal dialysis
Signs and symptoms of hypervolemia include rapid weight gain, swelling, cramping, high blood pressure, and heart problems
Kidney failure, congestive heart failure, liver failure, hormonal changes, and excessive IV fluids can cause hypervolemia
Treatment for hypervolemia involves diuretics to increase urine production and dialysis in extreme cases
Restriction of sodium and water intake is vital for the treatment of hypervolemia to return the extracellular compartment to normal
