The Broad Concern
The capstone began with a concern that almost every orthopedic nurse shares: patients recovering from joint replacement suffer from the side effects of the opioids they need for pain. On the 26-bed orthopedic unit where the author works, a composite described for this assignment, patients after hip and knee replacement routinely receive oxycodone for the first several days, and nurses spend part of every shift managing nausea, drowsiness, itching and constipation. The concern is real, and it is far too broad for a capstone. It spans several side effects with different causes and treatments, it involves prescribing decisions that belong to surgeons and anesthesiologists, and it offers no single measure that would show whether anything improved.
A capstone problem has to be narrow enough for one nurse, working within a nursing scope, to change something measurable in the time the course allows. The work of this module is subtraction: removing everything a single nurse cannot move until what is left is small enough to change and important enough to matter.
First Narrowing: One Side Effect
The first step was to choose one side effect. Nausea and drowsiness are often managed by adjusting or changing the opioid, which is a prescriber's decision. Constipation is different. Opioids slow gut motility by acting on opioid receptors in the gastrointestinal tract, and tolerance to this effect develops poorly, so constipation tends to persist as long as the drug is taken (Kumar et al., 2014). Prevention depends largely on nursing actions: giving scheduled laxatives, encouraging mobility and fluids, and recognizing early when a patient has not had a bowel movement. Constipation after surgery also causes real harm, including abdominal pain, nausea, reduced appetite and, in some patients, delayed discharge.
Choosing constipation narrowed the problem to something within nursing's reach. It was still too broad, because it did not say which patients, how constipation would be defined or what counted as a problem.
Second Narrowing: A Population and a Definition
The second step was to choose a population and a definition. The unit admits patients after hip and knee replacement, spine surgery and fracture repair. Fracture patients are often older and frailer, with more variable opioid use, and spine patients have different mobility restrictions. Elective hip and knee replacement patients form the most uniform group: similar ages, similar opioid regimens, early mobilization protocols and a predictable length of stay of two to four days. Limiting the problem to them makes a baseline meaningful and a change detectable.
Constipation needed a definition that a nurse could apply from the chart without a new assessment tool. The unit already documents bowel movements on the flowsheet, so the definition chosen was the absence of a documented bowel movement by 2359 on the third postoperative day. That threshold is practical rather than diagnostic; it does not capture stool form or discomfort, which a later module can add using a stool form scale (Lewis & Heaton, 1997), but it can be counted retrospectively and reliably from existing records.
The Baseline
With a population and definition in hand, the author reviewed the records of the 80 most recent consecutive patients admitted after elective hip or knee replacement, with approval from the unit manager and the hospital's quality department. Of the 80, 37, or 46 percent, had no documented bowel movement by the end of the third postoperative day. The bowel regimen ordered on admission was docusate alone for 56 patients, or 70 percent, although a randomized trial found that adding docusate to a stimulant laxative gave no benefit over adding a placebo (Tarumi et al., 2013). Senna was ordered as needed for 48 patients, but only 15 of those 48 received at least one dose before the third day.
Two points stand out. The regimen most often ordered is the one with the least evidence behind it, and the more effective option was available but rarely given. The problem is not a missing treatment; it is a treatment that exists on paper and does not reach the patient. That finding places the problem squarely within nursing practice, where a capstone can act on it.
What the Problem Is Not
Narrowing also means stating what the capstone will not attempt. It will not try to reduce opioid use after joint replacement, although multimodal analgesia that lowers opioid doses would likely reduce constipation too; that work belongs to the acute pain service and the surgeons, and it is already the subject of a separate hospital initiative. It will not address constipation in fracture or spine patients, whose needs differ enough to require their own baseline. It will not introduce new medications such as peripherally acting opioid antagonists, which are reserved for constipation that does not respond to laxatives and require prescriber decisions. And it will not rely on patient-reported symptoms at this stage, because the unit has no validated symptom tool in routine use and adding one would make the baseline impossible to compare.
Stating these exclusions protects the project from drift. When colleagues suggest adding fracture patients or a new drug, the problem statement gives a reason to say not yet, and the later modules can return to those ideas once the narrowed problem has been addressed. A capstone that tries to fix everything a colleague mentions usually finishes having changed nothing it can measure.
Testing the Narrowed Problem
The narrowed problem was tested against four criteria. It is significant, because nearly half of a large, predictable patient group experiences it and it causes discomfort and possible delays. It is within nursing scope, because the gap lies in how as-needed laxatives are given and how bowel status is monitored, though changing the default order set will need a prescriber partner. It is measurable from existing data, with a baseline already calculated. And it is feasible within the capstone timeline, because the unit admits about 25 joint replacement patients a month, enough to see a change within two to three months.
Stated in one sentence, the capstone problem is: on a 26-bed orthopedic unit, 46 percent of adults after elective hip or knee replacement have no documented bowel movement by the end of the third postoperative day, while an effective as-needed laxative that is already ordered for most of them is rarely given. Every later module in this capstone will be checked against that sentence.
Conclusion
The capstone began with a concern about opioid side effects and ended, three narrowing steps later, with a problem one nurse can move: nearly half of joint replacement patients on one unit reach day three without a bowel movement, and the laxative that could help sits unused in their orders. Each step removed something that was real but out of reach, and each left the problem more measurable. The result is a problem statement with a population, a setting, a definition, a baseline and a gap that nursing practice can close.

How this NUR 4093 Module 1 example is structured
NUR 4093 Module 1 often narrows a broad concern into a problem one person could actually move; your classroom's instructions decide the template and whether a PICOT question is required at this stage. This example shows the narrowing as a sequence, from a concern too broad to act on, through two intermediate versions, to a problem with a defined population, setting, measure and baseline. Each step says what was cut and why. The final section tests the narrowed problem against four criteria for a capstone and states it in one sentence, which is the sentence every later module will have to agree with.
NUR4093 Module 1 questions, answered
What does NUR4093 Module 1 usually ask for?
NUR4093 Module 1 often asks students to identify a practice problem for the senior capstone and narrow it to something one nurse can realistically influence. Many sections expect a problem statement with a population, setting, measure and some baseline evidence. Your classroom's instructions decide the template and whether a PICOT question is required at this stage.
How narrow should a capstone problem be?
Narrow enough that you can measure it with data you can actually get, change it within nursing scope and see a difference within the course timeline. A single side effect in one patient group on one unit is usually right; a broad topic such as pain management or patient safety is too wide to show any change.
Do I need baseline data in a capstone problem statement?
Baseline data make the problem concrete and give later modules something to compare against. A small, approved review of recent records or existing unit reports is usually enough. Report numerators and denominators, explain how you defined the problem and note what the baseline does not capture.
