and is widened in which of the following disorders?

• Early hypovolemic shock
• Increased intracranial pressure
• Cardiac tamponade
• Neurogenic shock - ANSWER-b. Increased ICP

Systemic vascular resistance (SVR) is decreased in which type of shock?

• Hypovolemic
• Cardiogenic
• Obstructive
• Distributive - ANSWER-d. Distributive

Rationale: Afterload (pressure) is low in distributive shock (neurogenic,

septic and anaphylactic) d/t vasodilation, and high in all other forms of shock d/t vasoconstriction.

• A 64 yr old female fell and transported to the ED via EMS for severe

• A patient is transported to the ED via EMS for headache, vomiting,

and progressive confusion after a fall three days ago. Which of the following head injuries is the most likely cause of these symptoms?

• Concussion

• Subdural hematoma
• Basilar skull fracture - ANSWER-c. Subdural hematoma

Rationale: Subdural hematomas are slower bleeds since venous. Seen

commonly in alcoholics, elderly, and from shaken impact syndrome

• Which of the following is the hallmark symptom of Prinzmetal's

angina?

• CP with physical exertion
• CP at rest d/t coronary vasospasm
• CP relieved by NTG and rest
• Atypical S/S such as epigastric pain - ANSWER-B. CP at rest d/t

coronary vasospasm

Rationale: The hallmark sign of Prinzmetals angina is pain at rest. It is

d/t coronary vasospasm, so may be seen w/ stimulant use.
