You are evaluating a patient with a suspected dissecting aortic aneurysm. The patient is bradycardia at a rate of 42 bpm. What most likely causes the bradycardia? A The massive loss of blood caused by the dissection B A dissecting aneurysm causes vagal stimulation C The dissection causes a release of epinephrine from the adrenal medulla D The break in the heart's conduction system

The nurse is administering atropine $0.3 \mathrm{mg} \mathrm{IV}$ to a 75-year-old patient with a heart rate of $45,$ and his heart rate decreases to 38. What is the most likely explanation? a. Atropine exerts its effects by stimulating the vagus nerve. b. The ordered dose was too low. c. Adenosine was indicated, not atropine. d. Atropine typically slows heart rate first and then increases it.
Which of the following could be a cause for stocks Adam syndrome? a. Third degree heart block b. Increased AV conduction c. Excessive sympathetic stimulation d. Low parasympathetic stimulation

A young woman is brought to the emergency department by ambulance after a severe motor vehicle accident. She is unconscious. Her blood pressure is 64/40 mm Hg; heart rate is 150 bpm. She is intubated and is being hand-ventilated. There is no evidence of head trauma. The pupils are 2 mm and reactive. She withdraws to pain. Cardiac examination reveals no murmurs, gallops, or rubs. The lungs are clear to auscultation. The abdomen is tense, with decreased bowel sounds. The extremities are cool and clammy, with thready pulses. Despite aggressive blood and fluid resuscitation, the patient dies. Questions: A. What is the likely diagnosis? Why? B. What are the major pathophysiologic causes of this condition? Which was likely in this patient? C. What pathogenetic mechanism accounts for this patient's unresponsiveness? For the cool, pale extremities?
