Study Notes
Care of Patients in Shock
Definition and Types of Shock
- Shock: inadequate tissue perfusion leading to cellular hypoxia and organ dysfunction
- Types of shock:
- Hypovolemic shock: decreased blood volume
- Cardiogenic shock: impaired cardiac function
- Distributive shock: abnormal distribution of blood flow
- Obstructive shock: obstruction of blood flow
- Septic shock: infection-induced inflammation
Stages of Shock
- Compensatory stage: body compensates for decreased perfusion
- Decompensatory stage: body's compensatory mechanisms fail
- Irreversible stage: organ damage and death
Assessment and Diagnosis
- Vital signs: tachycardia, tachypnea, hypotension, decreased urine output
- Physical examination: altered mental status, cool and clammy skin, delayed capillary refill
- Laboratory tests: complete blood count, electrolyte panel, blood urea nitrogen, creatinine
Management and Interventions
- Fluid resuscitation: crystalloids, colloids, and blood products
- Vasopressors: dopamine, norepinephrine, and vasopressin
- Inotropic agents: dobutamine and milrinone
- Cardiac support: invasive hemodynamic monitoring, mechanical ventilation
- Pain management: analgesics and sedatives
Care of Patients with Burn Injury
Classification of Burns
- First-degree burns: epidermal damage
- Second-degree burns: epidermal and dermal damage
- Third-degree burns: full-thickness skin damage
- Fourth-degree burns: damage to muscle, bone, and organs
Assessment and Diagnosis
- Burn size and depth estimation: rule of nines, Lund-Browder chart
- Burn severity assessment: American Burn Association (ABA) criteria
- Wound inspection: eschar, discharge, and signs of infection
Management and Interventions
- Fluid resuscitation: Parkland formula, colloid solutions
- Wound care: debridement, topical antibiotics, and dressing changes
- Pain management: analgesics, sedatives, and anxiolytics
- Infection prevention: antibiotics, wound cleaning, and isolation precautions
- Nutrition and hydration: high-calorie, high-protein diet, and hydration therapy
Care of Patients in Shock
Definition and Types of Shock
- Inadequate tissue perfusion leads to cellular hypoxia and organ dysfunction
- Four main types of shock: hypovolemic (decreased blood volume), cardiogenic (impaired cardiac function), distributive (abnormal blood flow distribution), and obstructive (obstruction of blood flow)
- Septic shock is a type of distributive shock caused by infection-induced inflammation
Stages of Shock
- Compensatory stage: body tries to compensate for decreased perfusion
- Decompensatory stage: body's compensatory mechanisms fail, leading to organ dysfunction
- Irreversible stage: organ damage and death occur
Assessment and Diagnosis
- Vital sign changes: tachycardia, tachypnea, hypotension, and decreased urine output
- Physical examination findings: altered mental status, cool and clammy skin, delayed capillary refill
- Laboratory tests: complete blood count, electrolyte panel, blood urea nitrogen, and creatinine
Management and Interventions
- Fluid resuscitation with crystalloids, colloids, and blood products
- Vasopressors (dopamine, norepinephrine, vasopressin) and inotropic agents (dobutamine, milrinone) to support blood pressure
- Cardiac support: invasive hemodynamic monitoring and mechanical ventilation
- Pain management: analgesics and sedatives
Care of Patients with Burn Injury
Classification of Burns
- First-degree burns affect only the epidermis
- Second-degree burns affect both epidermis and dermis
- Third-degree burns affect the full thickness of the skin
- Fourth-degree burns extend to muscle, bone, and organs
Assessment and Diagnosis
- Estimating burn size and depth: rule of nines and Lund-Browder chart
- Burn severity assessment using American Burn Association (ABA) criteria
- Wound inspection: eschar, discharge, and signs of infection
Management and Interventions
- Fluid resuscitation with Parkland formula and colloid solutions
- Wound care: debridement, topical antibiotics, and dressing changes
- Pain management: analgesics, sedatives, and anxiolytics
- Infection prevention: antibiotics, wound cleaning, and isolation precautions
- Nutrition and hydration: high-calorie, high-protein diet, and hydration therapy
Care of Patients in Shock
Definition and Types of Shock
- Inadequate tissue perfusion leads to cellular hypoxia and organ dysfunction
- Types of shock include:
- Hypovolemic shock: decreased blood volume due to hemorrhage or dehydration
- Cardiogenic shock: heart failure caused by myocardial infarction (MI) or cardiomyopathy
- Distributive shock: abnormal blood vessel tone resulting from sepsis or anaphylaxis
- Obstructive shock: mechanical obstruction caused by pulmonary embolism or cardiac tamponade
Assessment and Interventions
- Assess vital signs, including blood pressure, heart rate, respiratory rate, and temperature
- Evaluate level of consciousness, skin condition, and urine output
- Interventions include:
- Fluid resuscitation using IV fluids and blood products
- Vasopressors, such as dopamine and norepinephrine, to increase blood pressure
- Inotropes, such as dobutamine, to increase cardiac contractility
- Oxygen therapy to improve oxygen delivery
- Cardiac monitoring to track cardiac rhythm and function
Care of Patients with Burn Injury
Burn Classification
- First-degree burns: epidermal damage, redness, and pain
- Second-degree burns: partial-thickness burns, blisters, and pain
- Third-degree burns: full-thickness burns, charring, and no pain
- Fourth-degree burns: burns extending to muscle, bone, or organs
Assessment and Interventions
- Assess burn size and depth, as well as airway, breathing, and circulation (ABCs)
- Evaluate pain level and fluid status
- Interventions include:
- Wound care, including debridement and dressing changes
- Pain management using opioids and non-pharmacological methods
- Fluid resuscitation using the Parkland formula
- Infection prevention using antibiotics and wound cleaning
NCLEX Style Questions
Shock
- In hypovolemic shock, the priority intervention is initiating fluid resuscitation
- In cardiogenic shock, the next action is inserting an intra-aortic balloon pump
Burn Care
- In second-degree burns, the priority intervention is initiating fluid resuscitation
- Patients with third-degree burns are at risk for infection, hypovolemia, and respiratory distress
