Perfusion

 Definition: Adequate arterial blood flow through the tissues.  Key disorders: Heart failure, shock, hypertension.  Assessment cues: Cap refill >3 s, cool extremities, dusky skin, ↓ urine output.  Priority interventions: Elevate HOB, O ₂therapy, IV fluids/vasopressors as ordered, monitor MAP.  NGN link: Prioritize interventions for multiple clients with impaired perfusion.

Intracranial Regulation

 Definition: Mechanisms that facilitate or impair neurologic function.  Concepts: ICP, cerebral perfusion pressure (CPP), stroke types.  Signs of ↑ ICP: Cushing triad (↑ BP, bradycardia, irregular respirations), vomiting, LOC change.  Interventions: Head midline, HOB 30°, avoid hip flexion, osmotic diuretics (mannitol).  NGN application: Bow-tie question selecting meds & monitoring parameters.

Mobility

 Normal movement requires intact musculoskeletal & nervous systems.  Immobility complications: DVT, pressure injuries, constipation, atelectasis.  Fall-risk assessment: Morse, STRATIFY; implement multifactorial precautions.  Rehabilitation: ROM exercises, assistive devices, PT/OT collaboration.

Acid-Base Balance

 ROME: Respiratory Opposite, Metabolic Equal for pH/CO /HCO .₂ ₃  Common causes: DKA (metabolic acidosis), vomiting (metabolic alkalosis).  Arterial blood gas interpretation flowchart (pH → CO ₂ → HCO ).₃

Immunity

 Innate vs. adaptive immunity; vaccine schedules; herd immunity thresholds.  Autoimmune exemplars: SLE, RA – nursing care focuses on pain & fatigue management.

Elimination

 Urinary vs. bowel elimination patterns; neurogenic bladder strategies.  C. difficile isolation, stool specimen collection, laxative stewardship.

Cellular Regulation

 Oncogenesis, cancer staging (TNM), chemotherapy safety (PPE, extravasation).  Client education on neutropenic precautions.

Clinical Judgment (NGN Framework)

 Recognize cues → Analyze cues → Prioritize hypotheses → Generate solutions → Take action → Evaluate outcomes (RAPPGE).  Sample case study workflow with unfolding data tables.
