Study Notes
Critical Care Nursing
- Specialty focused on life-threatening responses and conditions as defined by AACN.
- Involves assessment, intervention initiation, and outcome evaluation.
Critical Care Units
- Known as Intensive Care Units (ICU) for acutely ill patients requiring specialized monitoring and support.
Progressive Care Units
- Also referred to as Intermediate Care or Step-down units, providing a transition from ICU to general care.
Nursing Responsibilities
- Ensure aseptic technique during care activities: suctioning, oral care, and patient positioning (elevating head of bed at least 30 degrees).
- Monitor for subtle changes to prevent complications like infections and Ventilator Associated Pneumonia (VAP).
Irreversible/Refractory Stage
- Identified by failure of 2-3 organs, leading to severe damage and risk of death.
- Treatment focus on comfort, family support, and safety.
Types of Shock
- Distributive Shock: Caused by excessive vasodilation and impaired blood flow. Subtypes include septic, neurogenic, and anaphylactic shock.
- Septic Shock: Characterized by hypotension despite fluid resuscitation, often linked to infection. Symptoms include respiratory compromise and arrhythmias.
- Anaphylactic Shock: Rapid allergic reaction often triggered by foods like peanuts; requires immediate intervention with IM epinephrine.
- Obstructive Shock: Involves physical blockages such as tension pneumothorax or pulmonary embolism hindering blood flow.
Management of Shock
- Fluid Resuscitation: Core treatment to expand blood volume with appropriate fluids; early intervention is crucial.
- Medication Administration: Sympathomimetics and vasodilators given IV for improving tissue perfusion.
- Assess for allergies and previous reactions in patients suspected of anaphylactic shock.
Diagnostic Studies
- No specific tests for shock exist; history and physical exams are vital. Key diagnostic studies include:
- 12-Lead ECG
- Continuous cardiac monitoring
- Chest X-ray (CXR)
- Continuous pulse oximetry
- Hemodynamic monitoring (CVP).
Nutritional Therapy
- Address protein-calorie malnutrition indicative of hypermetabolism; enteral feeding at 3000 calories/day is often necessary.
- Regular weight monitoring serves as an indicator of fluid status.
Nursing Interventions for Monitoring
- Ongoing assessment of physical and emotional health.
- Identifying trends in patient condition for timely intervention.
