What are common signs of respiratory distress in patients?

Increased respiratory rate, wheezing, and cyanosis are clear indicators of respiratory distress in patients. An elevated respiratory rate often signifies that the body is struggling to get enough oxygen, prompting the lungs to work harder. Wheezing, a high-pitched whistling sound during breathing, can indicate obstruction or narrowing of the airways, which is commonly associated with conditions like asthma or bronchitis. Cyanosis, a bluish tint to the skin or lips, is a serious sign that the body is not receiving sufficient oxygen, indicating a critical need for intervention.

While the other options may indicate health issues, they aren't specific signs of respiratory distress. Lethargy and drowsiness could suggest a range of conditions including fatigue or infections, but they do not directly signal respiratory issues. Excessive coughing and sneezing typically reflect irritation or infection in the respiratory tract but don't necessarily indicate distress. Pale skin and a rapid heartbeat can relate to numerous medical situations including shock or anemia, rather than being direct indicators of respiratory distress.
