patho test 4 chapter 25

Vomiting of stomach contents or continuous nasogastric suctioning may predispose to development of

metabolic acid deficit

Diarrhea and other lower intestinal fluid losses will contribute to

metabolic acidosis

Diarrhea causes

metabolic acidosis

The finding of ketones in the blood suggests that a person may have

metabolic acidosis

Emesis causes

metabolic alkalosis

Two primary acid-base disorders that are present independently are referred to as

mixed acid-base imbalance

The major buffer in the extracellular fluid is

bicarbonate

Which acid are kidneys unable to excrete

carbonic

Renal compensation for respiratory acidosis is evidence by

elevated bicarbonate ion concentration

The patient who requires the most careful monitoring for development of metabolic acidosis is a patient who

has had diarrhea for over week

Early manifestations of developing metabolic acidosis include

headache

Respiratory alkalosis is caused by

hyperventilation

Metabolic alkalosis is often accompanied by

hypokalemia

Respiratory acidosis may be caused by

hypoventilation

The body compensates for metabolic alkalosis by

hypoventilation

If an individual has fluffy compensated metabolic acidosis, the blood pH is

in the normal range

Respiratory acidosis is associated with

increased carbonic acid

Uncompensated metabolic alkalosis would result in

increased pH, increased HCO3-

A person who experiences a panic attack and develops hyperventilation symptoms may experience

numbness and tingling in the extremities

Full compensated respiratory acidosis is demonstrated by

pH 7.36, PaCO2 55, HCO3-36

A patient has been hospitalized several times in 6 months with severe, ECV depletion and hypokalemia resulting from chronic laxative abuse. Which blood gas results should be relayed to the physician ?

pH in high part of normal range PaO2 normal, PaCO2 high, bicarbonate high

A 3 year old is diagnosed with starvation ketoacidosis. What signs and symptoms should you anticipate in your assessment?

rapid, deep breathing, lethargy, abdominal pain

The _____ system compensates for metabolic acidosis and alkalosis

respiratory

A person with acute hypoxemia may hyperventilate and develop

respiratory alkalosis

The arterial blood gas pH= 7.52, PaCO2 + 30 mm Hg, HCO3- + 24 mEq/L demonstrates

respiratory alkalosis

Causes of metabolic acidosis include

tissue anoxia
