I moonlight in clinics on my off weeks to help pay down debt. The doctors I fill in for are often way too coddling of their patients for my tastes. A few of them will give into any demand. In my opinion this transforms you from a physician to a prescription-writing automaton. You aren't there to be their friend, you are there to do the right thing for them, despite their objections. You can be nice about it, but stand by your training and your knowledge. That's your job. Also, it's not a fever unless it's 100.5 or greater. I don't care if you "run low," that's the cutoff.
Patient: "I've been running a low-grade fever."
Me: "What was your temperature?"
Me (later in same conversation): "Ok, well this seems viral to me. I think with a few days of Tylenol and rest it will pass."
Patient: "You aren't going to give me an antibiotic?"
Me: "No, it's a viral illness and you have only had symptoms for two hours."
Patient: "Well, I will just wait until my regular doctor comes back and have her give me one. I can't believe they can't find a good doctor to fill in for her."
