In this instructional monologue, the speaker outlines the key signs and symptoms of pneumonia, emphasizing how the infection impairs gas exchange through mucus buildup and pulmonary edema, leading to decreased oxygenation. The body compensates with an increased respiratory rate and heart rate, as the heart attempts to maintain perfusion. Clinically, patients may exhibit decreased oxygen saturation, altered mental status, and use of accessory muscles for breathing. Additional infection-related findings include fever, auscultatory sounds such as wheezes, crackles, or rhonchi, a productive cough indicating mucus production, and pleuritic chest pain. The speaker concludes by promoting Nursing SOS flashcards for med‑surg nursing study.

Lets walk through some signs and symptoms for pneumonia. Pneumonia is an infection in the lungs and this decreases gas exchange through mucus buildup and edema or swelling in the lungs. So that gas exchange and that oxygenation is going to be decreased. Now what's going to happen here is an increased respiratory rate and an increased heart rate. Remember the heart and the lungs are best friends. If the lungs are in trouble, the heart will try to compensate by increasing the heart rate to try to get more blood flow to the body. You'll see decreased oxygen saturation, possibly mental status changes and accessory muscle use. And then with the infection, increased temperature, wheezes, crackles or rhonchi productive cough and pleuritic pain. Now remember productive cough. The lungs are producing gunk. So when you the patient has a productive cough and the lungs have that mucus in it, it's a productive producing cough. You can find all these med surg flashcards inside the nursing SOS shop.
