Question 1 of 5
A nurse is collecting data from a client who reports persistent vomiting, dizziness, palpitations, and numbness and tingling in his fingers and toes and around his mouth. The nurse notes the client's respirations are slow and shallow. The nurse should suspect that the client has developed which of the following acid-base imbalances?
Correct Answer: B
Rationale: The correct answer is B: Metabolic alkalosis. The client's symptoms of vomiting, dizziness, palpitations, numbness and tingling, along with slow and shallow respirations, indicate a loss of hydrogen ions (H⁺) and chloride ions (Cl⁻) due to prolonged vomiting, leading to metabolic alkalosis. Vomiting causes a loss of stomach acid (HCl), leading to an increase in blood pH. Respiratory acidosis (
C) results from inadequate ventilation, causing CO₂ retention and increased carbonic acid in the blood. Respiratory alkalosis (
D) is characterized by hyperventilation and decreased CO₂ levels. Metabolic acidosis (
A) involves a decrease in blood pH due to an excess of metabolic acids or a loss of bicarbonate ions.
