Stress ulcer prophylaxis, argued aloud and then defended in narrower form on paper, carries this MN650 Unit 5 seminar reflection, which leans on the SUP-ICU and REVISE trials. Searches like "mn 650 unit 5 assignment example", "mn650 unit 5 sample" and "mn650 unit 5 example" land here.

The case discussed is a composite prepared for teaching. Classmates are not named.
The Case
A composite 58-year-old man was intubated two days ago after a cardiac arrest at home, with return of circulation after twelve minutes. He is on mechanical ventilation, receiving enteral feeds through a nasogastric tube and subcutaneous heparin for clot prevention. His platelets are 88,000. He has no history of ulcers or bleeding. He was started on [ceftriaxone] for a suspected aspiration pneumonia.
My Opening Position
I opened by saying, "Every ventilated patient should be on pantoprazole; the bleeding it prevents is dangerous and the drug is cheap." I believed that stress ulcer prophylaxis was standard and that questioning it was a distraction from more important decisions.
The Objection
A classmate with years of bedside intensive care experience objected. Acid suppression, she said, may raise the risk of pneumonia, because stomach acid is one of the body's defenses against bacteria reaching the lungs, and of C. difficile infection, which is a real concern in a patient already on antibiotics. She asked whether the benefit was large enough, and in whom, to justify those risks for every ventilated patient.
The Evidence We Found
Two large trials settled much of the exchange. In SUP-ICU, about 3,300 adults in intensive care at risk of bleeding were randomized to pantoprazole or placebo; 90-day mortality did not differ, and clinically important gastrointestinal bleeding was less common with pantoprazole (Krag et al., 2018). That trial did not show a mortality benefit, but it also did not show a clear increase in pneumonia or C. difficile.
REVISE, published in 2024, enrolled 4,821 invasively ventilated adults. Clinically important upper gastrointestinal bleeding occurred in 1.0 percent of patients on pantoprazole and 3.5 percent on placebo, with no significant difference in 90-day mortality and no detectable increase in ventilator-associated pneumonia or C. difficile infection (Cook et al., 2024). Mechanical ventilation had long been identified as one of the strongest risk factors for clinically important bleeding in critically ill patients (Cook et al., 1994).
I granted the part of the objection that survives. Neither trial was powered to exclude small increases in pneumonia or C. difficile, and my patient is already on antibiotics, which is itself a risk for C. difficile. The worry is reasonable even if the trials did not confirm it.
My Revised Position
Pantoprazole is reasonable for invasively ventilated patients like those REVISE enrolled, and it should stop at extubation unless another indication exists.
This patient fits: he is ventilated, and his low platelets add to his bleeding risk. I would start pantoprazole. But a patient off the ventilator and eating would fall outside the population the trial studied, and I would not start it, or I would stop it, in that patient.
The Step the Seminar Exposed
The seminar exposed a problem I had not considered: acid suppression begun in intensive care is often continued long after the patient leaves, sometimes for months, without a reason anyone can name. The trials tested pantoprazole during ventilation, not after. So my revised position includes a stop date. When I write the order, I will write the condition for stopping it in the same order: "pantoprazole for stress ulcer prophylaxis while ventilated; stop at extubation." At transfer out of intensive care, I will check the medication list for any acid suppression without a current indication and stop it.
What I Would Say to the Team
If I were presenting this patient on rounds, I would now say: "He meets the REVISE population, ventilated with low platelets, so pantoprazole is reasonable, and I have written it to stop at extubation." If someone objected that he is on antibiotics and at risk of C. difficile, I would agree that the concern is real, say that the trials did not detect an increase, and add that the stop date limits his exposure to the days when his bleeding risk is highest. That answer is shorter than the one I gave at the start of seminar, and it is more honest, because it names both the benefit and the uncertainty.
I also noticed that my opening position rested on habit. I had seen pantoprazole ordered for nearly every ventilated patient during my clinical hours and had taken the pattern for evidence. The seminar taught me to ask which trial a habit rests on, and whether my patient resembles the people in it.
I came to the seminar with a rule and left with a narrower rule and a stop date, and I think the stop date is the more useful change.

How this MN650 Unit 5 example is structured
The reflection is chronological and depends on that order: position, challenge, evidence, revision. Each stage is short and the revision carries the most words, because the seminar rewards movement in thinking more than a restated case. The objection is reported fairly, in the classmate's terms, before any rebuttal, and the writer grants the part of it that survives: neither trial was powered to exclude small harms, and C. difficile remains a reasonable worry in a patient already on antibiotics. Risk factors carry the revised position. Low platelets and mechanical ventilation put this patient in the population REVISE enrolled; a patient off the ventilator and eating would fall outside it. Transfer is where the course's attention to step-down shows, since acid suppression begun in intensive care is often continued for months without a reason, and the reflection closes on that.

MN650 Unit 5 questions, answered
What if my position did not change during the seminar?
A reflection can show movement in reasoning without a reversal. Sharpening a view, adding a condition, or recognizing a weakness in the evidence behind it all count. The sample shows one version of that; if the actual seminar left a view intact, the reflection can explain which challenge tested it and why the view held.
Should the reflection include trial statistics?
Briefly, where they carry the argument. A single figure, such as the difference in clinically important bleeding, can anchor a claim better than a paragraph of summary. The sample reports what each trial found in plain terms, names its population, and avoids stacking numbers that the reflection never goes on to use.
Can the reflection use first person?
Most seminar reflections expect it, since the task is to describe how the writer's thinking moved. The sample uses first person in the reflective parts and plain third-person description for the trial evidence, which keeps the evidence from sounding like opinion. A section with different expectations would be followed instead, and the rubric usually settles it.
