A nurse in an emergency department is caring for a client who is receiving treatment for excessive ingestion of antacids. The nurse should identify that this client is at risk for which of the following acid- base imbalances?
Metabolic acidosis
Respiratory alkalosis
Metabolic alkalosis
Respiratory acidosis
The Correct Answer is C
C. Metabolic alkalosis is characterized by an increase in serum bicarbonate levels, resulting in an imbalance in the body's acid-base equilibrium towards alkalinity. Excessive ingestion of antacids, particularly those containing bicarbonate or calcium carbonate, can lead to an excessive accumulation of bicarbonate ions in the body, causing metabolic alkalosis.
A. Excessive ingestion of antacids would not typically cause metabolic acidosis because antacids containing bicarbonate or calcium carbonate actually increase bicarbonate levels, leading to alkalosis rather than acidosis.
B. Respiratory alkalosis occurs due to hyperventilation, leading to a decrease in carbon dioxide levels and subsequent alkalosis. Excessive ingestion of antacids is not typically associated with respiratory alkalosis.
D. Respiratory acidosis occurs due to hypoventilation, leading to an increase in carbon dioxide levels and subsequent acidosis. Excessive ingestion of antacids is not typically associated with respiratory acidosis.
