مريض في العناية على جهاز تنفس، وعند الشفط صارت الإفرازات صديدية كثيفة، وظهرت حرارة، وارتشاح جديد في الأشعة، والأكسجة ساءت. ما الأرجح؟

An ICU client on a ventilator now has thick purulent suctioned secretions, fever, a new infiltrate on X-ray and worsening oxygenation. What is most likely?

1. Simple atelectasis without infection
2. Cardiogenic pulmonary oedema only
3. Ventilator-associated pneumonia
4. Expected progress after 3 days on the ventilator

Answer: C) Ventilator-associated pneumonia. Purulent secretions, fever, new infiltrates and worsening oxygenation after 48 hours of ventilation suggest VAP. Cultures are taken and antibiotics started per protocol.
