Case study
I would have to say Pneumonia, because of the fever.and rust colored sputum. I have the other symptoms right now, r/t type A flu, diagnosis reactive airway disorder. The organism could be the initial virus, or an advanticious bacteria. The high temp seems to point to the virus, as does the green sputum. I would want a cbc with diff and sed rate, chest xray, sputum c+s for definitive dx. UA to r/o a Uti causing the fever, and mono spot, to r/o mono, as this is a student situation, + a TB test to r/o tb. I would expect if its purely respiratory, that the ua would be ok, the WBC would be high, and if viral even higher, the sed rate high. The chest xray would show an area of consolidation. Of course you cannot make an accurate diagnosis until you examine the patient and see those lab results. I would treat with Tylenol for fever+aches, plenty of fluids, quiafenesin, and dextromethorpan to ease the coughs, and a broad spectrum antibiotic until all test results were returned.

I agree with Martina, probably a pneumonia. Organism might be a gram + cocci, streptococci, for example. I disagree with the choice to use a cough suppressant. Most evidence is now showing that it is better to "cough up" the sputum in order to heal. ABX therapy is certainly indicated. But, before starting Tx, we shoud get blood cultures to r/o sepsis. Although the pneunomia index scale would not indicate hospitalization, close monitoring is needed. May consider a bronchodialator to help with breathing and bringing up some of that phelgm. Tylenol is a good choice for an antipyretic, but initially, one should avoid it's use because it can mask fever possible indication ABX failure or worsening of illness. Good luick with your case study!
