Module 1 Acid-Base Balance The Concept of Acid-Base Balance 1) A client who has been fasting and has ketones in the urine is brought to the emergency department (ED) unconscious. 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. 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 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. Starvation would not result in metabolic alkalosis. D) 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.

NLN Competencies: Knowledge and Science: Relationships between knowledge/science and quality and safe patient care. Nursing Process: Assessment Learning Outcome: 1.2. Differentiate alterations in acid-base balance. MNL LO: Analyze the concept of acid-base balance and its application to nursing care. 2) The nurse is caring for a client in the emergency department. Which factors will the nurse identify that increase the client's risk for metabolic acidosis? Select all that apply. A) Abdominal fistulas B) Chronic obstructive pulmonary disease C) Pneumonia D) Chronic 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 condition such as an abdominal fistula which can cause the loss of bicarbonate from the intestine
