Question 1 of 5
A nurse is assisting with the admission of a client who is hyperventilating, reports lightheadedness and paresthesias, and has blurred vision and a new onset of confusion. The nurse should suspect that the client has developed which of the following imbalances?
Correct Answer: D
Rationale: The correct answer is D, respiratory alkalosis. Hyperventilation causes excessive loss of carbon dioxide, leading to respiratory alkalosis. This is evidenced by lightheadedness, paresthesias, blurred vision, and confusion due to decreased carbon dioxide levels in the blood. Metabolic acidosis (
A) is characterized by low pH and bicarbonate levels, not seen in this scenario. Metabolic alkalosis (
B) is due to excess bicarbonate, which is not present in hyperventilation. Respiratory acidosis (
C) is caused by retention of carbon dioxide, opposite of what is seen in hyperventilation.
