Foundational Decision Making: When approaching ATI-style priority questions, the first step is to evaluate if the client is oxygenating, perfusing, and protecting their airway.
Priority Hierarchies:
- Acute vs. Chronic: Acute changes generally outrank chronic expected abnormalities (e.g., new confusion in a COPD patient outranks their chronic barrel chest).
- Unstable vs. Stable: Unstable findings outrank stable ones.
- Actual vs. Potential: Actual physiological problems take precedence over potential risks.
Critical Findings (Never Normal):
- New-onset confusion or decreasing level of consciousness (LOC).
- Chest pain.
- Severe dyspnea.
- Hypotension and signs of shock.
- Absent pulses.
- Rapidly worsening pain.
System-Specific Focuses:
- Electrolytes: Focus on heart rhythm, muscle function, neurological status, and seizure risk.
- Endocrine/Diabetes: Identify fluid status and blood glucose levels first.
- Respiratory: Do not rely on pulse oximetry alone. Assess work of breathing, mental status, arterial blood gases (ABGs), breath sounds, and tracheal position.
Specific Frameworks:
- ABCs (Airway, Breathing, Circulation): Severe dyspnea, stridor, absent breath sounds, tracheal deviation, cyanosis, SpO2 not improving, and hypotension are top priorities.
- Safety: Includes falls, seizures, aspiration, bleeding, infection, self-harm, elopement, burns, and sensory impairment. Nursing actions include padding side rails for seizures, using call lights, and maintaining neutropenic or bleeding precautions.
- Expected vs. Unexpected: Expected symptoms are managed; unexpected symptoms must be reported immediately (e.g., report chest pain after thrombolytics, absent pulse after a cast, or sudden vision loss).
- Least Invasive First: Perform assessments (vitals, glucose, pulses) before interventions unless the client is actively "crashing."
- Maslow's Hierarchy: Physiological needs (oxygen, fluids, glucose, electrolytes, elimination, temperature) outrank psychosocial needs.
Fatal Conditions (Immediate Priorities):
- Airway obstruction, respiratory failure, tension pneumothorax, and pulmonary embolism.
- Shock, cardiac tamponade, and malignant dysrhythmias.
- Severe electrolyte imbalances (hypo/hyperkalemia) and glucose crises (hypoglycemia, DKA/HHS fluid collapse).
- Thyroid storm, adrenal crisis, and disseminated intravascular coagulation (DIC).
- Sepsis, compartment syndrome, and ruptured abdominal aortic aneurysm (AAA).
- Sudden vision loss (retinal detachment, acute glaucoma).
High-Yield Comparison: Diabetes and Endocrine Disorders
DKA vs. HHS vs. Hypoglycemia:
- DKA (Diabetic Ketoacidosis):
- Pathophysiology: No insulin leads to fat breakdown, resulting in ketones, metabolic acidosis, and dehydration.
- Typical Client: Type 1 diabetics; triggered by infection, missed insulin, MI, or stress.
- Assessment/Labs: High glucose, positive ketones, anion gap acidosis, Kussmaul respirations, and fruity breath. Total body potassium is low even if serum levels look high.
- Priority: Fluids first, then regular insulin IV. Monitor potassium before starting insulin.
- HHS (Hyperglycemic Hyperosmolar Syndrome):
- Pathophysiology: Enough insulin available to prevent ketosis, but not enough to utilize glucose, leading to extreme hyperglycemia (>600) and hyperosmolar dehydration.
- Typical Client: Type 2 diabetics, older adults, and those with poor intake or illness.
