What Is the Nursing Process?

The nursing process is the structured, five-step framework nurses use to think through and deliver patient care: assessment, diagnosis, planning, implementation, and evaluation. For a surgery patient, this framework is what turns a chaotic series of events, admission, consent, anesthesia, incision, recovery, into a coherent, monitored journey. The nursing process is not paperwork. It is a clinical reasoning tool, and learning to apply it correctly is one of the clearest ways nursing students demonstrate readiness for safe practice. Many students reach out for nursing assignment help specifically when asked to build a full ADPIE care plan around a surgical case study, because the assignment requires synthesizing pathophysiology, pharmacology, and patient communication into one continuous plan.

According to the NCBI Bookshelf overview of the nursing process, the framework was first introduced by Ida Jean Orlando in 1958 and has since become the standard structure taught in nursing programs across the United States and the United Kingdom. The nursing process blends critical thinking, evidence-based practice, and patient-centered goals into five sequential, interrelated steps. Each step depends on the one before it. Skipping or rushing the assessment step, for example, produces a diagnosis built on incomplete information, which in turn produces a plan that does not actually fit the patient in front of you.

What Does ADPIE Stand For?

ADPIE is the acronym nurses and nursing students use to remember the five steps in order: Assessment, Diagnosis, Planning, Implementation, Evaluation. It is not a one-time checklist completed at admission and forgotten. ADPIE is cyclical. A surgical patient’s plan of care is reassessed constantly, before surgery, immediately afterward in the post-anesthesia care unit, and again on the surgical floor as recovery progresses. Each loop through the cycle either confirms that the plan is working or signals that something needs to change.

Why Does the Nursing Process Matter Specifically for Surgery Patients?

Surgical patients face a unique risk profile compared to medical patients admitted for chronic disease management. They move through anesthesia, tissue trauma, blood loss, and a recovery period where pain, immobility, and infection risk all spike at once. The nursing process gives the surgical nurse a repeatable method for catching problems early, rather than reacting to a crisis. A 2026 narrative review in Cureus examining peri-anaesthesia nursing found that structured, protocol-driven nursing care during the perioperative period is directly linked to improved patient safety outcomes in the post-anaesthesia care unit and the immediate postoperative window.

Who Uses the Nursing Process in Surgical Settings?

The nursing process is applied by registered nurses across every point of the surgical journey: the pre-admission testing nurse who completes the initial workup, the circulating nurse and scrub nurse in the operating room, the post-anesthesia care unit (PACU) nurse managing emergence from anesthesia, and the surgical floor nurse overseeing days of recovery. Students preparing case studies on surgical nursing often need to demonstrate how the same five-step process looks different in each of these roles while still following the same underlying logic.

The Three Phases of Surgical Care the Nursing Process Must Cover

Before walking through each ADPIE step in detail, it helps to understand the three phases of surgical care that the nursing process has to flex around. Each phase has different risks, different priorities, and different members of the care team involved.

What Is the Difference Between Perioperative and Postoperative Nursing?

Perioperative nursing is the umbrella term covering all three phases above, the preoperative, intraoperative, and postoperative periods combined. Postoperative nursing refers specifically to care delivered after the surgery is complete. Students sometimes use the two terms interchangeably in assignments, which costs marks. A care plan built for the perioperative period needs assessment data and interventions for all three phases, not just recovery.

How Long Does the Postoperative Recovery Phase Last?

Postoperative recovery is generally described in three stages. The immediate phase covers the first hours after surgery in the PACU, focused on emergence from anesthesia. The intermediate phase covers the hospital stay, where mobility, pain, and wound healing are managed. The extended recovery phase continues at home and can last days to months depending on the procedure. A growing body of research on Enhanced Recovery After Surgery (ERAS) protocols shows that structured, nurse-led care across all three of these stages shortens hospital length of stay and lowers complication rates, with one 2025 cohort study reporting fewer 30-day complications when ERAS elements were consistently applied.

Assessment: Building the Foundation of Surgical Patient Care

Assessment is the first and arguably most important step of the nursing process, because every later decision depends on the quality of the data gathered here. For a surgical patient, assessment begins well before the operating room. The initial nursing assessment involves systematic collection of subjective data (what the patient reports) and objective data (what the nurse observes, measures, or finds in the chart), according to the NCBI Bookshelf chapter on nursing admission assessment.

What Is Included in a Preoperative Nursing Assessment?

A complete preoperative assessment covers far more than vital signs. It typically includes the following:

• Medical and surgical history: prior surgeries, anesthesia complications, chronic conditions such as diabetes, hypertension, or COPD that raise surgical risk
• Medication reconciliation: anticoagulants, insulin, herbal supplements, and any drug that needs to be held or adjusted before surgery
• Allergy history: drug allergies, latex sensitivity, and reactions to anesthesia in family members
• Baseline vital signs and physical exam: cardiovascular and respiratory status, skin integrity, nutritional status
• Laboratory and diagnostic data: CBC, coagulation studies, electrolytes, ECG, imaging as ordered
• Psychosocial assessment: anxiety level, coping mechanisms, support system, cultural and spiritual considerations
• Functional and discharge-planning assessment: mobility baseline, home environment, who will assist with recovery

What Is a Functional Health Pattern Assessment?

Many nursing programs require students to organize assessment data using Marjory Gordon’s Functional Health Patterns, an eleven-category framework covering everything from nutrition to coping and stress tolerance. Using this structure for a surgical patient ensures nothing gets missed, particularly psychosocial and self-care domains that are easy to overlook when the focus is on the surgical site. Students working through this model in coursework often consult the functional health patterns framework to organize their data systematically before moving to diagnosis.

What Risk Factors Should the Nurse Identify Before Surgery?

Preoperative assessment exists in large part to catch risk factors early. Age over 65, obesity, smoking history, poorly controlled diabetes, anticoagulant use, and a history of deep vein thrombosis all change the surgical and anesthesia plan. Identifying these factors during assessment, rather than discovering them mid-procedure, is what allows the surgical team to adjust anesthesia choice, prophylactic antibiotics, and postoperative monitoring in advance.

Intraoperative and Postoperative Assessment

Assessment does not stop once the patient enters the operating room. The circulating nurse continuously assesses positioning, skin integrity at pressure points, and physiological status throughout the procedure. Once the patient reaches the PACU, assessment shifts to airway patency, level of consciousness, oxygen saturation, surgical site bleeding, and pain. This is where the nursing process becomes visibly cyclical: assessment in the PACU directly feeds a new round of diagnosis, planning, and intervention specific to recovery from anesthesia.

Nursing Diagnosis: Turning Assessment Data Into Clinical Judgment

Once assessment data is collected, the nurse must interpret it. This is the diagnosis step, and it is where many nursing students confuse a nursing diagnosis with a medical diagnosis. A medical diagnosis (appendicitis, osteoarthritis) names a disease. A nursing diagnosis names a patient response that nursing care can address, things like pain, anxiety, or risk for infection. The North American Nursing Diagnosis Association International (NANDA-I) maintains the standardized terminology most U.S. and UK nursing programs use to write these diagnoses in a consistent, comparable format.

What Is the Format of a Nursing Diagnosis?

A complete nursing diagnosis statement typically follows the PES format: Problem, Etiology (related to), and Signs/Symptoms (as evidenced by). For example: “Acute pain related to surgical tissue trauma as evidenced by patient-reported pain score of 8/10 and guarding of the incision site.” Risk diagnoses, used when a problem has not yet occurred but is likely, drop the “as evidenced by” portion since there are no current symptoms to cite.

Common Nursing Diagnoses for Surgical Patients

Below is a working reference table of nursing diagnoses that appear frequently across surgical case studies, along with the phase of care where each is most relevant and a representative nursing intervention.

Risk Diagnoses vs. Actual Diagnoses in Surgical Care

Surgical nursing leans heavily on risk diagnoses because much of preventive nursing care exists precisely to stop a problem before it starts. Writing “Risk for Infection” rather than waiting for an actual infection to diagnose reflects how surgical nursing actually works: proactive, not reactive. Case studies that only list actual diagnoses, with no risk diagnoses, often miss the preventive backbone of perioperative nursing care, a point frequently emphasized in coursework built around the nursing care plan and nursing process framework.

How Many Nursing Diagnoses Should a Surgical Care Plan Include?

There is no fixed number, but most academic surgical case studies expect three to five prioritized nursing diagnoses, ranked using a framework such as Maslow’s Hierarchy of Needs or the ABC (Airway, Breathing, Circulation) priority model. Airway and breathing-related diagnoses are prioritized first in the immediate postoperative period, followed by circulation, pain, infection risk, and finally psychosocial or educational diagnoses.

Planning: Setting Goals and Building the Surgical Care Plan

Planning translates the diagnosis into action. For every nursing diagnosis identified, the nurse sets a measurable, patient-centered goal and selects interventions designed to achieve it. Planning for a surgical patient has to stretch across the entire continuum, what happens before surgery, what is monitored during, and what milestones define a safe recovery afterward.

What Makes a Strong Nursing Goal? The SMART Framework

Goals in a surgical care plan should be Specific, Measurable, Achievable, Realistic, and Time-bound (SMART). “Patient will feel better” is not a usable goal. “Patient will report pain at or below 4/10 within 30 minutes of analgesic administration” is. SMART goals give the evaluation step something concrete to measure against later.

How Does ERAS Fit Into Surgical Care Planning?

Enhanced Recovery After Surgery (ERAS) protocols are a structured, multimodal approach to perioperative planning built specifically to speed recovery and reduce complications. ERAS planning typically bundles preoperative patient education, carbohydrate loading instead of prolonged fasting, minimally invasive surgical technique where possible, opioid-sparing multimodal pain control, and early postoperative mobilization and oral intake. A randomized controlled trial on early mobilization within an ERAS framework found that patients following a structured mobilization plan reached ambulation milestones significantly faster than those receiving standard postoperative instructions. Nursing students writing surgical care plans are increasingly expected to reference ERAS principles rather than older, more passive postoperative routines.

What Is the PICOT Framework and How Does It Relate to Planning?

When a care plan is built around a specific clinical question, for example, whether early ambulation reduces postoperative pneumonia compared to delayed mobilization, nursing students often use the PICOT format (Population, Intervention, Comparison, Outcome, Time) to structure the evidence search behind their plan. This format is widely taught alongside the PICOT framework for evidence-based practice and pairs naturally with the planning step of ADPIE, since both require translating a clinical question into a measurable, testable statement.

Implementation: Carrying Out Surgical Nursing Interventions

Implementation is where the plan becomes action. This is the step most visible to patients and families: medication administration, wound care, repositioning, education, and emotional support. Implementation for a surgical patient spans three distinct settings, each with its own demands.

Preoperative Implementation: Preparing the Patient

Preoperative nursing interventions focus on safety checks and education. The nurse confirms informed consent is signed and understood, verifies the surgical site has been marked correctly, completes the preoperative checklist, administers prophylactic antibiotics or anticoagulant adjustments as ordered, and provides teaching on what to expect during recovery, including pain management options, expected activity restrictions, and incentive spirometer use.

What Should Preoperative Patient Teaching Include?

Effective preoperative teaching covers the procedure in plain language, what the patient will feel like waking up, pain management expectations, deep breathing and coughing exercises to prevent pneumonia, and early mobilization expectations. Patients who receive structured preoperative education report lower anxiety and tend to participate more actively in their own recovery, a pattern echoed across multiple ERAS studies that build preoperative counseling into the protocol itself.

Intraoperative Implementation: Maintaining Safety in the Operating Room

During surgery, nursing implementation centers on the circulating nurse and scrub nurse roles: maintaining the sterile field, verifying instrument and sponge counts, positioning the patient to prevent nerve and skin injury, and supporting the surgical team’s adherence to safety protocols. The WHO Surgical Safety Checklist, a nineteen-item tool used at three critical points in every procedure, is one of the clearest examples of the nursing process operating inside the operating room itself. Research synthesizing checklist adoption found that consistent use is associated with measurable reductions in surgical complications and mortality across both high-income and resource-limited hospital settings.

Postoperative Implementation: Supporting Recovery

This is where the bulk of surgical nursing implementation happens, and it is organized below by phase.

How Does Pain Management Fit Into Implementation?

Postoperative pain management has moved decisively toward multimodal analgesia, combining non-opioid medications, regional anesthesia techniques, and non-pharmacological comfort measures to reduce reliance on opioids alone. This shift is not just about comfort. Research on ERAS-based nursing interventions in spinal surgery patients found that structured multimodal pain protocols led to significantly lower pain scores at 24 and 48 hours, along with shorter hospital stays and faster return to daily activities compared to standard postoperative pain care.

Why Is Early Mobilization Such a High Priority?

Early ambulation, getting the patient out of bed within the first 24 hours where clinically appropriate, reduces the risk of pneumonia, deep vein thrombosis, pressure injury, and constipation. It is one of the most consistently supported interventions across ERAS literature. Nurses implement this through structured mobility schedules, adequate pain control before activity, and close coordination with physical therapy. Documentation of mobility progress is a routine part of nursing documentation practice on a surgical unit.

Communication as an Implementation Skill

Implementation is not only physical care. Clear, structured nurse-to-patient and nurse-to-team communication directly affects surgical outcomes. Tools like SBAR (Situation, Background, Assessment, Recommendation) structure handoffs between shifts and escalate concerns to physicians efficiently. Strong nurse-patient communication also reduces preoperative anxiety and improves adherence to discharge instructions, both of which influence how smoothly recovery proceeds after the patient leaves the hospital.

Evaluation: Measuring Recovery Against the Plan

Evaluation closes the loop. The nurse compares the patient’s actual outcomes against the goals set during planning and decides whether the plan worked, needs adjustment, or needs to be replaced entirely. Evaluation is continuous in surgical nursing, not a single end-of-stay event.

What Does Successful Postoperative Evaluation Look Like?

For the pain example used earlier, evaluation asks directly: did the patient’s pain reach 4/10 or below within 30 minutes of intervention? If yes, the goal was met and the plan continues. If not, the nurse reassesses, perhaps the dose was inadequate, the patient under-reported pain out of fear of dependency, or a non-pharmacological measure needs to be added, and the plan is revised. This reassessment is, in effect, a return to the assessment step, which is exactly why the nursing process is described as cyclical rather than linear.

What Are Common Discharge Readiness Criteria After Surgery?

• Vital signs stable and within the patient’s normal baseline range
• Pain controlled on an oral regimen the patient can manage independently at home
• Surgical site clean, dry, and showing no signs of infection
• Patient tolerating oral intake appropriate to the procedure
• Patient ambulating safely or able to use assistive devices appropriately
• Patient or caregiver demonstrates understanding of wound care, medications, and warning signs
• Follow-up appointment scheduled and confirmed

How Does Evidence Support Outcome-Based Evaluation?

Evaluation in modern surgical nursing increasingly leans on standardized recovery milestones rather than subjective impressions of “doing well.” A 2024 cohort study on nurse-led ERAS programs reported that structured outcome tracking, length of stay, time to first ambulation, and 30-day complication rate, allowed care teams to identify which patients were falling behind expected recovery trajectories early enough to intervene, rather than after a complication had already developed. This is the practical value of the evaluation step: it turns recovery from a guess into a measured process.

Nursing Theories That Inform Surgical Care Planning

The nursing process does not operate in a vacuum. Several foundational nursing theories shape how nurses interpret assessment data and choose interventions for surgical patients specifically.

Dorothea Orem’s Self-Care Deficit Theory

Orem’s theory frames nursing care around the patient’s ability, or temporary inability, to meet their own self-care needs. A surgical patient who could independently manage all activities of daily living before surgery suddenly cannot dress a wound, ambulate safely, or manage pain alone in the early postoperative period. This is precisely the self-care deficit Orem’s framework describes, and it directly informs discharge planning. Students applying this lens often reference Orem’s self-care deficit theory when justifying why discharge teaching and caregiver involvement are prioritized in the planning step.

Virginia Henderson’s Need Theory

Henderson defined nursing’s unique function as helping patients perform activities they would do unaided if they had the strength, will, or knowledge to do so, and helping them gain independence as quickly as possible. For surgical recovery, this translates directly into early mobilization and structured teaching rather than simply performing tasks for the patient. The framework is covered in depth in resources on Henderson’s need theory.

How Do Nursing Theories Differ From the Nursing Process Itself?

The nursing process is the method, the five-step structure for delivering care. Nursing theories are the underlying philosophy that shapes how a nurse interprets what they find during assessment and what “good outcomes” actually mean for a given patient. A broader comparison of major frameworks is available in a comprehensive guide to nursing theories and models for students building theoretical foundations into a surgical case study.

Common Mistakes When Applying the Nursing Process to Surgical Patients

Mistake: Treating the Nursing Process as Linear, Not Cyclical

Students sometimes write a care plan as if assessment happens once and the rest of the steps follow in a straight line to discharge. In real surgical nursing, the cycle repeats constantly, every shift, every PACU check, every time a new symptom appears. A strong surgical case study should show at least one example of reassessment triggering a revised plan.

Mistake: Skipping the Psychosocial and Educational Dimensions

It is easy to focus a surgical care plan entirely on physical recovery, pain, wound, mobility, while ignoring anxiety, knowledge deficits, and discharge readiness. Strong academic work and strong clinical practice both treat psychosocial assessment as equally important, not an afterthought tacked onto the end of the plan.

Mistake: Weak Documentation

A care plan that is well thought out but poorly documented fails both academically and clinically. Documentation needs to reflect the full ADPIE cycle: what was assessed, what was diagnosed, what was planned, what was done, and what the outcome was. This is also a legal requirement in real practice, since the patient’s chart is the official record of care delivered.

Key Organizations Behind Surgical Nursing Standards

Strong academic work on the nursing process benefits from showing awareness of the institutions that set and enforce the standards behind surgical patient care, not just the clinical steps themselves.

NANDA International (NANDA-I)

NANDA-I maintains the standardized taxonomy of nursing diagnoses used across most U.S. and UK nursing programs. Without this shared language, two nurses describing the same patient problem might use entirely different terms, undermining continuity of care across shifts and facilities.

The Association of periOperative Registered Nurses (AORN)

AORN sets evidence-based perioperative practice standards specifically for the intraoperative phase, covering everything from sterile technique to patient positioning and surgical counts. These standards directly shape the implementation step of the nursing process inside the operating room.

The World Health Organization (WHO)

The WHO’s Surgical Safety Checklist, introduced in 2008, standardized critical safety pauses before anesthesia, before incision, and before the patient leaves the operating room. Multiple studies cited in perioperative literature associate consistent checklist use with measurable reductions in surgical mortality and complication rates worldwide.

The Joint Commission

The Joint Commission accredits U.S. hospitals and sets National Patient Safety Goals that directly intersect with surgical nursing, including correct-site surgery verification, medication reconciliation, and standardized handoff communication between shifts and care settings.

Building a Surgical Care Plan: A Step-by-Step Checklist

1. Review the patient’s chart, history, and surgical plan before beginning assessment.
2. Conduct a complete preoperative assessment covering physical, psychosocial, and discharge-planning domains.
3. Identify and prioritize three to five nursing diagnoses, written in correct PES format.
4. Set a SMART goal for each diagnosis, with both short-term and long-term targets.
5. Select evidence-based interventions matched specifically to each goal, referencing current research where possible.
6. Implement the plan, documenting actions and the patient’s response in real time.
7. Evaluate outcomes against each goal at defined intervals, and revise the plan if goals are not met.
8. Repeat the cycle as the patient moves from preoperative, to intraoperative, to postoperative, to discharge.
