Clinical safety: Educational summaries simplify real care. Actual decisions require current orders, institutional policy,
patient-specific assessment, scope of practice, and qualified clinical judgment.

behaviors.
Catalog-confirmed scope
The September 2026 WGU catalog describes D446 as medical-surgical nursing care for diverse adults with acute
and chronic conditions. Named areas are perioperative nursing and the neurological, hematological, renal,
cardiovascular, endocrine, and musculoskeletal systems, with the nursing process, clinical judgment, health
promotion, maintenance, and social determinants of health.
Universal clinical-judgment sequence
Recognize cues → analyze cues → prioritize hypotheses → generate solutions → take action → evaluate outcomes.
Reassess after every meaningful intervention. An answer that treats but never evaluates response is usually
incomplete.

Preoperative safety
Recognize: Verify identity, procedure/site, consent completion, allergies, NPO status, medications, labs, and
baseline assessment.
Priority: Resolve discrepancies before transport; confirm consent was obtained by the responsible provider and
witness signature per policy.
Therapy/monitor: Antibiotic timing, VTE prophylaxis, medication holds and glucose plans are order-specific.
Teach: Incentive spirometry, early mobility, pain plan, tubes/lines, and postoperative expectations.
Escalate: Wrong-patient/site/procedure risk, unstable condition, unresolved consent, or new abnormal finding.
Post-anesthesia recovery
Recognize: Airway obstruction, hypoventilation, hypoxemia, hypotension, pain, nausea, temperature and
consciousness changes.
Priority: Airway and ventilation first; position, stimulate, support oxygenation and escalate per recovery criteria.
Therapy/monitor: Reversal agents, antiemetics, analgesia and fluids require respiratory/hemodynamic
reassessment.
Teach: Deep breathing, splinting, mobility and safety after sedation.
Escalate: Stridor, apnea, difficult arousal, persistent hypoxemia, shock, hemorrhage or malignant hyperthermia
signs.
Postoperative complications
Recognize: Atelectasis, pneumonia, VTE, urinary retention, ileus, infection, dehiscence and bleeding.
Priority: Trend vital signs, oxygenation, wound/drainage, pain, output and mobility; address the most immediate
physiologic threat.
Therapy/monitor: Pulmonary hygiene, prophylaxis, analgesia, fluids and early ambulation as ordered.
Teach: Report calf/chest symptoms, fever, wound separation, heavy drainage or inability to void.
Escalate: Sudden dyspnea, hemorrhage, evisceration, sepsis, anuria or rapidly worsening pain.
