Critical Illness Shock Flashcards
Patients with suspected infection can be predicted to have poor outcomes typical of sepsis if they have at least two of the following clinical criteria:_____
respiratory rate ≥22 breaths/min
altered mental status
systolic blood pressure ≤100 mmHg.
Shock clinical indicators
Reduced mean arterial pressure (MAP)
Tachycardia, tachypnea
Cool skin and extremities
Acute altered mental status
Oliguria
MAP = ___
Cardiac Output (CO) × Systemic Vascular Resistance (SVR)
Diminished CO
Narrow pulse pressure (systolic BP – diastolic BP)
Cool extremities, delayed capillary refill
Check proximal extremities for relative “coolness.”
Increased CO
Widened pulse pressure (low diastolic pressure)
Warm extremities,
bounding pulses
Rapid capillary refill
Patient has increased JVP with noted crackles on PE. Patient has possible _____ shock and should be evaluated for _____
cardiogenic shock
MI
Patient has decreased JVP with orthostatis. Patient has possible _____ shock and should be initially given _____
hypovolemic shock
IVF
Positive-pressure ventilation increases right ventricular afterload, decreasing _____
cardiac output.
A 45-year-old female with a history of septic shock presents with warm, bounding extremities and a widened pulse pressure. What is the next best step in management?
A) Administer intravenous fluids
B) Initiate inotropes
C) Begin antibiotics and aggressive resuscitation
D) Perform an echocardiogram
B
A patient with shock presents with cold extremities, hypotension, and a history of significant blood loss. Physical examination reveals orthostasis and decreased JVP. What is the most appropriate intervention?
A) Inotropes and afterload reduction
B) Intravenous fluid resuscitation
C) Vasopressor administration
D) Perform echocardiogram
B
A 60-year-old female presents with refractory hypotension despite volume resuscitation. She has cold extremities and a “flat” inferior vena cava on ultrasound. She fails to improve with fluid therapy. What is the next diagnostic consideration?
A) Evaluate for adrenal crisis
B) Perform an echocardiogram for heart failure
C) Initiate vasopressors
D) Administer broad-spectrum antibiotics
