Exam 43: Fluid and Electrolyte Balance

Extracellular fluid depletion is the last line of defense against dehydration.

Cerebrospinal fluid is part of the:

Vomiting or diarrhea each may cause fluid and electrolyte output to exceed intake.

Because the GFR is almost constant, the amount of hormone in the blood has the biggest impact on urine volume.

Too much potassium can be more dangerous than too little potassium.

The amount of water removed by the kidney as urine is greater than all the other sources of water loss combined.

Physiologically, the valence of an electrolyte is more important than the number of particles in a solution.

Because fat tissue contains the least amount of water of any tissue in the body, obese people tend to have a lower percentage of body water.

ANH assists in the regulation of urine volume.

How does an electrolyte imbalance lead to fluid imbalances?

Match each term with its corresponding definition. -An ion with a negative charge

Which of the following is not a method used for parenteral administration?

Which of the following electrolytes is not a cation?

The most crucial mechanisms for maintaining fluid balance adjust output to intake, as in the aldosterone mechanism and the renin-angiotensin mechanism.

Which of the following is not considered a "transcellular fluid"?

The most accurate measurement of the body's store of potassium is an arterial blood sample.

The composition of sodium in the blood plasma is equal to _____ mEq/L.

Intracellular fluids constitute about 50% of body weight.

With an equal milligram percent in solution, calcium would have a(n) _____ milliequivalent than potassium.

Positive ions of electrolytes are cations and are attracted to a cathode.
