Abstract
Older adults on medical units are woken repeatedly at night for tasks that are scheduled rather than needed. Sleep loss is one of several modifiable contributors to delirium, which is common, often preventable and linked to poor outcomes after discharge. This paper proposes a protected sleep window from 2300 to 0500 for patients 65 and older on a 30-bed medical unit, in which routine tasks pause, comfort measures precede sleep aids and specific exceptions preserve safety. Evidence supports multicomponent delirium prevention strongly and sleep-specific changes more thinly. The paper describes the protocol, a plan staged by the Iowa Model, and a run-chart evaluation with balancing measures and a stopping rule. [Implementation status is reported by the author.]
Introduction
At 0412 on a Tuesday, a nursing assistant switches on the overhead light in room 14 and helps an 84-year-old woman with dementia onto the bed scale. It is her fourth interruption since 2300: vital signs at midnight, a repositioning at 0200, a blood draw at 0400 and now the weight, due before morning rounds. She has slept about ninety minutes. At 0800, she cannot name the day, pulls at her IV line and does not recognize her daughter. Her 4AT is positive.
None of the four tasks was triggered by a change in her condition. Each was scheduled, and each could have been moved. This paper argues that protecting sleep in older medical inpatients is a nursing intervention with evidence behind it, and that a nurse-controlled night protocol can deliver it safely. The argument moves from where the problem sits in nursing's scope, to what the evidence can and cannot support, to what a night nurse would do differently, and finally to how anyone would know whether it worked.
Where the Project Sits
Among the four spheres of care in the AACN Essentials (American Association of Colleges of Nursing, 2021), the project belongs first to disease prevention, because delirium usually begins in the hospital rather than arriving with the patient. It belongs second to chronic disease care, because dementia, heart failure and Parkinson's disease raise the risk and change how night care is delivered. Its restorative claim ends at discharge destination. Palliative care marks its boundary: patients on comfort-focused plans are excluded. The question that follows is how strongly the evidence supports the prevention claim.
Evidence
Delirium is common in older inpatients, and roughly a third or more of cases may be preventable (Inouye et al., 2014). Patients who develop it are more likely to die, to move into a care facility or to develop dementia in the years that follow (Witlox et al., 2010). Three themes emerged from [11] sources.
First, multicomponent programs reduce new delirium. The original Hospital Elder Life Program trial, which bundled a sleep protocol with five other components, cut the rate of new delirium by about a third, to 9.9 percent in the program group (Inouye et al., 1999). Pooled analysis of similar programs found lower odds of delirium and falls (Hshieh et al., 2015), and the Cochrane reviewers, looking at wards other than intensive care, agreed and rated the evidence moderate in certainty (Burton et al., 2021). In each, sleep was bundled with other components, so its separate effect is unknown.
Second, night disruptions can be reduced. Hospital nights are noisy, and medical inpatients sleep less than at home (Yoder et al., 2012). Using record prompts and nurse education, the SIESTA project cut the number of vital-sign checks and medicine passes that fell during the night (Arora et al., 2019), though it did not measure delirium.
Third, sleep medicine carries risk and can be reduced. Sleeping pills of both the benzodiazepine and the newer hypnotic kind are on the Beers list of drugs for older adults to avoid (American Geriatrics Society Beers Criteria Update Expert Panel, 2023), and a nonpharmacologic sleep protocol cut the use of sleep medicine among older medical inpatients from 54 to 31 percent (McDowell et al., 1998).
The gap is clear. Nothing in the set isolates a sleep window run by nurses and measures delirium as its outcome on a general medical ward. The project is therefore a practice project that applies well-supported principles, not a test that could prove sleep alone prevents delirium. The next question is what the protocol asks a night nurse to do.
The Protocol
The protected sleep window runs from 2300 to 0500 for older patients on 4 West. At 2200, the nurse clusters care, treats pain and offers toileting, and asks about the patient's home bedtime routine. At 2230, lights dim, doors close, and earplugs, eye masks and comfort measures are offered before any sleep aid. During the window, routine vital signs, weights, baths and clock-timed repositioning pause, while hourly safety rounding continues by flashlight.
Patients are woken and assessed for any of these exceptions: a new admission; an early warning score that reaches the unit's trigger level; a rise of [two] or more points since the last observations, added after night staff raised it; an insulin infusion; neurological checks; a request from the patient or family; or nurse concern. Patients on heparin infusions keep their [0400] draws, a narrowing the laboratory requested for timed anticoagulation levels. Time-critical medications, such as Parkinson's medicines, are not moved. The next question is how the protocol reaches the unit.
Plan
Staging follows the revised Iowa Model, from team formation through a pilot to a decision on adoption (Iowa Model Collaborative, 2017). The team includes night and day charge nurses, a clinical nurse specialist, a pharmacist, a hospitalist and the laboratory supervisor. Nursing-controlled components start on the nurse manager's approval; changes to draws, medication times and vital-sign orders are requests to their owners, each with a fallback. Staff learn the protocol in a twelve-minute huddle module that opens with a case and tests the exceptions. Families receive a card explaining why visits thin out at night. The pilot runs for [56] nights after a baseline of equal length. The remaining question is how the team will judge the result.
Evaluation
Four objectives are measured: nursing-scheduled interruptions in the window, from record timestamps; checklist completion; sedative-hypnotic doses; and twice-daily 4AT screening. Incident delirium, counted only among patients negative on admission, and sleep quality on the Richards-Campbell Sleep Questionnaire (Richards et al., 2000) are reported as outcomes without targets. Overnight rapid response calls, night falls and late medications are balancing measures. Weekly run charts are read by standard rules for shifts, trends and runs (Perla et al., 2011), and [two] protocol-related rapid response calls would halt the pilot for review.
Implementation Status
[The author reports here what has been completed: approvals obtained, staff educated, baseline nights audited and any pilot nights run, in the past tense.] Everything above describes the protocol and plan as they stand; the evaluation describes what will be done.
Discussion
Implications. If the protocol reduces interruptions and sedative use without harm, it offers a nurse-led contribution to delirium prevention that needs little money and no new staff. It also extends the chronic and restorative spheres: patients with dementia keep their home routines, and a patient who leaves the hospital without delirium is more likely to go home.
Limitations. The project runs on one unit over a short pilot, so its results may not transfer. The pre-post design cannot establish cause. The sleep questionnaire was validated in intensive care rather than on medical units. Interruptions measured by timestamps may lag the tasks themselves.
Sustainability. If adopted, the checklist becomes part of night orientation, the family card part of admission packets, and the interruption measure part of the unit's quarterly quality report.
Conclusion
The woman in room 14 did not need to be weighed at 0412. A night nurse with a protocol, a list of exceptions and the backing of the unit could have let her sleep. The evidence does not promise that this alone would have spared her delirium, but it supports protecting sleep as part of preventing it, and the plan offers a way to find out.

How this NU480 Unit 8 example is structured
A single claim organizes the paper, and every section is asked what it contributes to that claim. The vignette makes the problem concrete; the spheres section shows where the claim applies; the evidence section shows how far it can be supported and where it cannot; the project sections show what a night nurse would actually do; the evaluation shows how anyone would learn whether it worked. Each section's last sentence names the question the next one takes up, which keeps the thread visible across 18 pages. Verb tense marks status throughout: the protocol and plan in the present, completed activity in the past and in brackets, evaluation in the future. The discussion returns to the four spheres to argue implications for chronic and restorative care. Limitations are specific: one unit, a short pilot, an instrument validated elsewhere.

NU480 Unit 8 questions, answered
Can I paste my earlier assignments into the capstone paper?
Most instructors expect the earlier work to be revised, not pasted. Carry forward the content, update anything that changed, and redraft so the paper speaks in one voice with consistent figures throughout. The sample condenses each earlier deliverable and carries the progress report's changes into every section that depends on them.
How long is a typical BSN capstone paper?
Your instructions set the length, and it varies by program. Many capstone papers run somewhere between fifteen and twenty-five pages before references, with appendices for tools and materials. The sample sits near eighteen pages and moves the checklist, family card and measures table to appendices so the argument stays readable from start to finish.
What if my project was never implemented?
That is common, and the paper can still be strong. Present the project as designed, the evaluation as planned, and your own activities as they actually happened. The sample keeps implementation status in a separate bracketed paragraph and writes the rest in terms that do not claim outcomes, which is how many capstones end.
