Article: Vital Signs (knowledge) Which condition can cause bradypnea? Alcohol consumption Anxiety states Pulmonary embolism Respiratory failure

Bradypnea refers to an abnormally slow breathing rate. Among the given options, respiratory failure (option D) is the condition most likely to cause bradypnea. Respiratory failure occurs when the respiratory system fails to adequately exchange oxygen and carbon dioxide, leading to a decrease in the breathing rate. Alcohol consumption (option A) may lead to respiratory depression, but it is not a direct cause of bradypnea. Anxiety states (option B) typically result in increased respiratory rate (hyperventilation) rather than bradypnea. Pulmonary embolism (option C) can cause tachypnea (rapid breathing) rather than bradypnea. Therefore, the correct answer is option D.
