Exam 33: Acid-Base Balance

Edith is pregnant and experiencing repeated vomiting episodes.Her obstetrician becomes concerned,admits her to the hospital,and begins intravenous administration of normal saline.How will this help Edith?

On the pH scale,as the value moves from 14 toward 7,the concentration of hydroxide ions decreases.

An increase in blood pH accelerates the renal tubule excretion of both hydrogen and ammonia.

The loss of chloride from the stomach will tend to lower the pH of the body.

Respiratory acidosis is also:

The compensatory mechanisms that respond to acidosis may lead to hyperkalemia and cause heart blockage or death.

Identify the main buffer pairs present in body fluids.How do these buffer pairs function to limit large changes in pH?

If NaOH were buffered by H-HCO₃,what would not occur?

Ketone bodies are associated with cellular metabolism of:

Some athletes engage in a technique called bicarbonate loading that is said to counteract the lactic acid buildup.This practice raises concerns because excess bicarbonate intake:

Explain the pH scale

The metabolism of ribonucleotides increases the hydrogen ion concentration of extracellular fluid.

Explain why a change in pH is so detrimental to the functioning of the body.

The most acidic substance in the body is:

Which of the following type(s)of acids would be produced as a result of glucose catabolism?

What substances or processes in the body might cause a change in the blood pH?

Match each term with it corresponding definition. -bicarbonate deficit that could be caused by untreated diabetes mellitus or starvation

The pH of the blood is maintained at approximately:

Citrus fruits are mainly acid-forming when metabolized.

An increase in respiratory rate would result in a decrease in all of the following except:
