Not a Treatment Failure Yet: Fever at Hour Sixty of Ceftriaxone in a 66-Year-Old With Pyelonephritis
NU652 · Unit 1 Discussion Board Post
Posted by [Student Name]
The patient is composite; temperatures, hours and values are bracketed.
Initial Post
My patient this week is a [66]-year-old woman admitted with right flank pain, rigors and pyuria. By hour [40], her urine culture grew Escherichia coli susceptible to ceftriaxone, the drug she had been on since admission. At hour [60] she still spiked to [101.9] F, and at rounds the word "failure" came up, along with a suggestion to broaden to a carbapenem and order a CT.
I argued that she has not failed yet, and I would like the group to test that. Susceptibility matters first: fever on a drug the organism resists is a mismatch, not a slow response, but her organism is susceptible. The second point is timing. In a chart review of patients hospitalized with pyelonephritis, the median duration of fever on treatment was 34 hours, 26 percent were still febrile at 48 hours and 13 percent at 72 hours, and fever sometimes took four days to settle without any complication being found (Behr et al., 1996). She is at hour [60], which puts her in a group that is common and usually uncomplicated.
The third point is that persistent fever and lack of improvement are different claims. Her daily peaks have fallen from [103.1] to [102.4] to [101.9]. Her flank pain is less, she ate most of her breakfast, her white count has fallen from [18.2] to [12.4], her blood pressure has held at [124/70] and her creatinine is flat at [0.9]. Every sign except the thermometer says she is getting better, and the thermometer is heading the same way, only more slowly.
That does not mean waiting indefinitely. I would stop the clock early and image for obstruction or abscess if her pressure fell, her creatinine rose, her white count climbed again, her pain worsened or blood cultures stayed positive. Without those, I would continue ceftriaxone and reassess at [72 to 96] hours, when a persistent fever becomes a reason to look.
My question for classmates: where would you put the line, and would you image her today if she had diabetes or a history of kidney stones?
Reply to a Classmate Who Would Image Today
You would order a renal ultrasound today because an obstructed, infected kidney is a surgical emergency, and I agree that obstruction is the one cause we cannot afford to miss. For this patient I would still wait, because her pain is improving and her creatinine is flat, which argues against obstruction. But your point about diabetes is a good one: patients with diabetes are more likely to have complications such as emphysematous pyelonephritis, and I would lower my threshold for imaging in that group.
Reply to a Classmate Who Would Broaden Coverage
You raised the concern that a resistant organism could be hiding behind the culture result. I think that is less likely here, since the culture grew a single susceptible organism and she is improving on every other measure. Broadening to a carbapenem would expose her to a wider drug without a clear reason, and IDSA guidance on pyelonephritis bases the antibiotic on the culture and local resistance rather than on fever alone (Gupta et al., 2011). If a second organism appeared or she worsened, I would change my view.

Reading the NU 652 Unit 1 instructions
The opening NU652 discussion asks what to do when a first plan seems not to be working. Most prompts give or invite a case in which a patient has not improved on the expected schedule and ask whether the treatment has failed, what the usual time course of response is, and what findings would justify changing course. You are expected to take a position, support it with evidence on the natural history of the condition and name the triggers that would change your mind. The initial post is usually 350 to 500 words with two scholarly sources, and two replies are due later in the week. A composite patient keeps the case shareable.
How the NU 652 Unit 1 example is put together
The example opens with the case in a few lines and states its position by the second sentence, so a reader knows the post argues for patience with conditions attached. Susceptibility is settled before timing, because fever on a drug the organism resists is a different problem. The timing paragraph uses a chart review of fever duration in pyelonephritis with its actual percentages. A paragraph separates the thermometer from everything else, listing falling peaks, less pain, better appetite, a falling white count and stable pressure and creatinine. The post then names five findings that would end the wait and closes with a question about diabetes and stones. Each reply takes one classmate's argument seriously and answers it.
Reading the NU652 Unit 1 grading rubric
The Unit 1 rubric typically scores clinical reasoning, use of evidence, application to the case, peer engagement and writing mechanics. Reasoning earns full points when the post distinguishes failure from slow response and names what would change the plan. Evidence counts when the source addresses the natural history of the condition rather than treatment in general; a chart review of fever duration is more useful here than a general antibiotic reference. Application is judged on whether the numbers from the case are used. Peer replies must add a new point or source. Mechanics include APA citations and clear, concise writing. Posts that argue a position rather than listing options tend to score higher.
NU652 Unit 1 help: mistakes that cost points
The most common error in this unit is treating persistent fever as proof of failure and broadening antibiotics without checking susceptibility or time course. Another is arguing for patience without naming the findings that would end it, which reads as complacency. Students often cite a treatment guideline for a question about natural history. Some posts ignore the other signs of improvement and focus only on temperature. Replies may simply agree or repeat the original argument. Finally, remember that a patient with diabetes, a stone or an obstruction changes the threshold for imaging, and say so if your case includes one of them.

Whatever condition appears in the opening prompt, cellulitis, pneumonia or a kidney infection, pass it along with any posting rules on length and citations. The first sample is free and back within 24-48h, arguing its own clock for that condition and naming the finding that would cut the wait short. The paper above is an original model document written by our desk, not a submitted student paper and not an official Purdue University Global document.

NU652 Unit 1 questions, answered
Could the sample post use a different infection?
Yes. The response window changes with the condition, so a post on cellulitis, pneumonia or bacteremia would cite a different timeline and a different set of early-exit findings. Tell us the case your prompt supplies, and the sample builds its clock around that infection and the evidence behind it, keeping the same order: coverage first, then time, then exceptions.
Why not simply broaden the antibiotic now?
Because the culture already shows the drug covers the organism. Broadening at that point adds toxicity and resistance pressure without addressing the likely reasons for a persisting fever: a response still under way, an obstruction or abscess, or a noninfectious cause. The post argues for imaging or patience depending on the findings, which is usually what this unit is testing.
How do replies to classmates differ from the initial post?
They are shorter, often 100 to 150 words, and they work best when they add something the original post lacked, such as a case, a counterargument or a newer source. The sample's two replies do exactly that. Your own posting requirements, including how many replies are expected, come from your course and are followed as written.
Where can I find a free NU652 Unit 1 sample paper?
This page holds the full NU652 Unit 1 discussion post with both replies, including the fever timeline and the findings that would stop the clock. If your case involves a different infection, the desk can prepare a free post built on that case.
How long does fever last in treated pyelonephritis in NU652 Unit 1?
In the chart review the sample cites, the median was 34 hours, 26 percent of patients were still febrile at 48 hours and 13 percent at 72 hours, and fever sometimes took four days to resolve without complications.
