Flashcards in Common Causes of Ward Emergencies Deck (10):
What can cause hypotension?
Hypovolemia (iatrogenic, hemorrhage); sepsis; MI; cardiac dysrhythmia, hypoxia, false reading (e.g. wrong cuff size, arterial line twist or clot), PTX, PE, cardiac tamponade, medications (e.g. morphine)
How do you act in the setting of hypotension?
ABCs, examine, recheck BP, IV access, IV bolus, labs (e.g. Hct), EKG, vital signs monitoring, CXR, supplemental O2, check medications/history, give IV antibiotics if sepsis likely, compress all bleeding sites
What are the common causes of postoperative hypertension?
Pain (from catecholamine release), anxiety, hypercapnia, hypoxia (which may also cause hypotension), preexisting condition, bladder distention
What can cause hypoxia or SOB?
Atelectasis, pneumonia, mucous plug, PTX, PE, MI, dysrhythmia, venous blood in ABG syringe, SAT% machine malfunction or probe malposition, iatrogenic (wrong ventilator settings), severe anemia, hypovolemia, low cardiac output, CHF, ARDS, fluid overload
How do you act in the setting of hypoxia?
ABCs, physical exam, vital signs monitoring, supplemental O2, IV access, ABG, EKG, CXR
What can cause mental status changes?
Hypoxia (until ruled out), hypotension (e.g. cardiogenic shock), hypovolemia, iatrogenic (narcotics, benzodiazepines), drug reaction, alcohol withdrawal, drug withdrawal, seizure, ICU psychosis, CVA, sepsis, metabolic derangements, intracranial bleeding, urinary retention in the elderly
What are the signs of alcohol withdrawal?
Confusion, tachycardia, autonomic instability, seizure, hallucinations
What are the causes of tachycardia?
Hypovolemia, third-spacing, pain, alcohol withdrawal, anxiety/agitation, urinary retention, cardiac dysrhythmia (e.g. sinoventricular tachycardia, AFib with rapid rate), MI, PE, beta-blocker withdrawal, anastomotic leak
What are the causes of decreased urine output?
Hypovolemia, urinary retention, Foley catheter malfunction, cardiac failure, MI, ATN, ureteral or urethral injury, abdominal compartment syndrome, sepsis
