A client arrives in the emergency department with epigastric pain and prolonged vomiting. Assessment findings include rapid and shallow respirations, dry and flushed skin, weakness, and lethargy. What is the primary nursing concern?

Answer: Metabolic alkalosis

Explanation: Metabolic alkalosis refers to a metabolic condition in which the tissue's pH is increased above the normal range (7.35-7.45). This occurs as a result of decrease in the concentration of Hydrogen ion, which results to increased bicarbonate in the body system. It can also be caused by direct increase in the bicarbonate concentrations.
