TEST BANK: NURSINGA CONCEPT-BASED APPROACH TO LEARNING, VOLUMESI, II & III, 3RD EDITION, PEARSON EDUCATIONNursing: A Concept-Based Approach to Learning Vol. 1 2 & 3, 3e (Pearson) Module 1 Acid-Base Balance The Concept of Acid-Base Balance 1) A client is brought to the emergency department (ED) after passing out in a local department store. The client has been fasting and has ketones in the urine. Which acid-base imbalance would the nurse expect to assess in this client? A) Metabolic acidosis B) Respiratory alkalosis C) Metabolic alkalosis D) Respiratory acidosis Answer: A Explanation: A) A client who is fasting is at risk for development of metabolic acidosis. The body recognizes fasting as starvation and begins to metabolize its own fatty acids into ketones, which are metabolic acids. Starvation would not result in respiratory acidosis or alkalosis or in metabolic alkalosis. B) A client who is fasting is at risk for development of metabolic acidosis. The body recognizes fasting as starvation and begins to metabolize its own fatty acids into ketones, which are metabolic acids. Starvation would not result in respiratory acidosis or alkalosis or in metabolic alkalosis. C) A client who is fasting is at risk for development of metabolic acidosis. The body recognizes fasting as starvation and begins to metabolize its own fatty acids into ketones, which are metabolic acids.

Select all that apply. A) Abdominal fistulas B) Chronic obstructive pulmonary disease C) Pneumonia D) Acute renal failure E) Hypovolemic shock Answer: A, D, E Explanation: A) Metabolic acidosis is rarely a primary disorder. It usually develops during the course of another disease; presence of abdominal fistulas, which can cause excess bicarbonate loss; acute renal failure; and hypovolemic shock. Chronic obstructive pulmonary disease and pneumonia place the client at risk for respiratory acidosis with the increased retention of carbon dioxide in the blood.

The nurse interprets these findings as indicative of which condition? A) Metabolic acidosis B) Respiratory alkalosis C) Respiratory acidosis D) Metabolic alkalosis Answer: C Explanation: A) If the pH is decreased and the PaCO2 is increased with a normal HCO3, it is uncompensated respiratory acidosis. Uncompensated respiratory alkalosis has an increased pH, decreased PaCO2, and normal HCO3. Uncompensated metabolic acidosis has a decreased pH, normal PaCO2, and decreased HCO3. Uncompensated metabolic alkalosis has an increased pH, normal PaCO2, and increased HCO3. B) If the pH is decreased and the PaCO2 is increased with a normal HCO3, it is uncompensated respiratory acidosis. Uncompensated respiratory alkalosis has an increased pH, decreased PaCO2, and normal HCO3. Uncompensated metabolic acidosis has a decreased pH, normal PaCO2, and decreased HCO3. Uncompensated metabolic alkalosis has an increased pH, normal PaCO2, and increased HCO3. C) If the pH is decreased and the PaCO2 is increased with a normal HCO3, it is uncompensated respiratory acidosis. Uncompensated respiratory alkalosis has an increased pH, decreased PaCO2, and normal HCO3. Uncompensated metabolic acidosis has a decreased pH, normal PaCO2, and decreased HCO3. Uncompensated metabolic alkalosis has an increased pH, normal PaCO2, and increased HCO3. D) If the pH is decreased and the PaCO2 is increased with a normal HCO3, it is uncompensated respiratory acidosis. Uncompensated respiratory alkalosis has an increased pH, decreased PaCO2, and normal HCO3. Uncompensated metabolic acidosis has a decreased pH, normal PaCO2, and decreased HCO3.

Which result indicates that the metabolic alkalosis is compensated? A) pH 7.32 B) PaCO2 18 mmHg C) HCO3 8 mEq/L D) PaCO2 48 mmHg Answer: D Explanation: A) A normal pH level is 7.35-7.45. A pH of less than 7.35 is acidosis. A PaCO2 level of 18 mmHg is low and is seen in respiratory alkalosis. A HCO3 level of 8 mEq/L is low and is most likely associated with metabolic acidosis. In metabolic alkalosis, there is an excess of bicarbonate. To compensate for this imbalance, the rate and depth of respirations decrease, leading to retention of carbon dioxide. The PaCO2 will be elevated. B) A normal pH level is 7.35-7.45. A pH of less than 7.35 is acidosis. A PaCO2 level of 18 mmHg is low and is seen in respiratory alkalosis.

Which of the tests will provide the most accurate indicator of the client's acid-base balance? A) Arterial blood gases (ABGs) B) Pulse oximetry C) Sputum studies D) Bronchoscopy Answer: A Explanation: A) ABGs are done to assess alterations in acid-base balance caused by respiratory disorders, metabolic disorders, or both. A bronchoscopy provides visualization of internal respiratory structures. Sputum studies can provide specific information about bacterial organisms. Pulse oximetry is a noninvasive test that evaluates the oxygen saturation level of blood.
