PART A1 True/False 1. Septic shock has the lowest mortality rate of the various types of shock. 2. Symptoms of shock are not evident until there is a 2,000-mL loss of fluid volume. 3. A myocardial infarction is a leading cause of cardiogenic shock. 4. Once shock develops, treatment depends on its type and level. 5. In shock, the pulse pressure tends to narrow as the falling systolic pressure nears the diastolic pressure. PART A2 Fill in the Blank 1. __________ is a severe allergic reaction that follows exposure to a substance to which a person is extremely sensitive. 2. __________ are neurotransmitters that stimulate responses via the sympathetic nervous system. 3. __________ refers to decreased oxygen reaching the cells. 4. __________ is the pressure of the blood in the right atrium or venae cava. 5. In shock, __________ L of intravenous fluid is administered for every 1 L of fluid lost. PART B Shock is a life-threatening condition occurring in a body when oxygen to tissues and cells are inadequate, usually from disrupted blood flow. Shock develops in three stages or events for one reason or another; blood volume decreases, which then causes the heart to fail as a pump, causing blood vessels to dilate peripherally, leading the body to try to compensate. As compensation ensues, shock progresses, and if left uncorrected, organs become damaged and death is ultimate. 1. What are the four types of shock and how do they affect the body? 2. What are the three categories of distributive shock? 3. What are the stages of shock? PART C1 True/False 1. Natural disasters include fires, explosions, and acts of terrorism. 2. Internal radiologic contamination occurs from exposure to fallout on skin, hair, and clothing. 3. Three high-priority agents likely to be used in bioterrorist warfare include anthrax, botulism, and smallpox. 4. Botulinum antitoxin is the only immediate treatment after exposure to lessen the severity of botulism. 5. There are many vesicant antidotes available that are effective for a variety of vesicant agents. PART C2 Fill in the Blank 1. A(n) __________ is a conventional explosive device (e.g., dynamite) that spreads small amounts of radiation in the form of powder or pellets. 2. A(n) __________ is an explosion that produces an intense wave of heat, light, air pressure, and radiation. 3. __________ prevents radioactive iodine from reaching the thyroid gland by saturating the gland with nonradioactive iodine. 4. __________ is a highly contagious disease caused by the variola virus. 5. Blistering agents, also known as __________, are chemicals that damage exposed skin and mucous membranes on contact.
