A nurse is assessing a client who has left-sided heart failure. Which of the following findings should the nurse identify as a manifestation of pulmonary congestion?

A. Bradypnea: This refers to a slower than normal respiratory rate, which is not a typical manifestation of pulmonary congestion. In fact, pulmonary congestion often leads to tachypnea (increased respiratory rate). B. Jugular vein distention: This is more indicative of right-sided heart failure or fluid overload rather than left-sided heart failure, where the primary issue is related to pulmonary congestion. C. Weight gain: While weight gain can occur due to fluid retention in heart failure, it is not specific to pulmonary congestion and can be seen in both left-sided and right-sided heart failure. D. Frothy, pink sputum: This is a classic manifestation of pulmonary congestion and indicates the presence of fluid in the lungs, often seen in left-sided heart failure. The pink color is due to the presence of blood, which may leak into the alveoli due to increased pressure. This finding is critical and should be closely monitored.
