A nurse is caring for a patient on a ventilator in the critical care unit. The nurse understands which of the following are common manifestations of ventilator-associated pneumonia?

Choice A rationale Low blood pressure and bradycardia are not typical. manifestations of ventilator-associated pneumonia (VAP). VAP is an. infectious process that commonly triggers a systemic inflammatory response. This response usually presents with an increase in heart rate (tachycardia). and fever. While a severe, septic presentation could lead to hypotension,. bradycardia is a rare finding and not a primary symptom. Choice B rationale Nausea and vomiting are common gastrointestinal. symptoms, but they are not specific or typical manifestations of. ventilator-associated pneumonia (VAP). VAP is a pulmonary infection, and its. primary symptoms relate to the respiratory and systemic inflammatory. responses. These include fever, leukocytosis (elevated WBC count), and changes. in pulmonary secretions, rather than GI disturbances. Choice C rationale Weight gain and hypertension are not manifestations of. ventilator-associated pneumonia (VAP). Weight gain is often a result of fluid. retention or anabolism, while VAP is a catabolic, infectious process that can. lead to weight loss. Hypertension is also not a direct consequence of VAP,. which typically presents with hypotension in severe septic cases. Choice D rationale Fever, an elevated white blood cell (WBC) count, and. pulmonary infiltrates are classic manifestations of ventilator-associated. pneumonia (VAP). Fever is a systemic response to infection, and an elevated. WBC count (leukocytosis) is the body's attempt to fight the infection. Pulmonary infiltrates, as seen on chest imaging, represent the inflammatory. response and fluid accumulation in the lung tissue.
