17 Questions
Which term refers to the accumulation of fluid in body spaces, such as ascites in the abdominal cavity or pleural effusion in the pleural space?
Third spacing
What is the term used for low circulating volume, which can occur due to hemorrhage or plasma-to-interstitial fluid shift?
Hypovolemia
In which spacing does edema in tissues occur, leading to an excessive accumulation in the interstitial fluid and possibly the intracellular fluid?
Second spacing
What is the goal when managing dehydration or fluid volume deficit, according to the text?
Replace water & electrolytes, give blood if due to hemorrhage
Which term describes the abnormal retention of fluids, such as in congestive heart failure (CHF), resulting in high circulating volume?
Hypervolemia
Where is the fluid located in the extracellular space?
In the space between cells
Which electrolyte is mainly focused on in terms of distribution in the body?
Sodium (Na+)
