Which factor is least likely to contribute to respiratory alkalosis? A) Pain B) Salicylate overdose C) Increased metabolic states D) Hypoventilation

Understand the Problem

The question is asking which factor among the given options is least likely to cause respiratory alkalosis, a condition characterized by a deficiency of carbon dioxide in the blood due to increased respiration. We would evaluate the choices based on their known effects on respiration and acid-base balance.

More Information

Respiratory alkalosis typically results from hyperventilation, which causes excessive expulsion of CO2. Hypoventilation, on the other hand, leads to increased CO2 levels in the blood, contributing to respiratory acidosis instead.

Tips

A common mistake is to confuse hypoventilation with hyperventilation. Always remember that hyperventilation decreases CO2, leading to alkalosis, while hypoventilation increases CO2, resulting in acidosis.
