PN3 exam 31. a condition, not a disease: What is shock?
2. hypovolemic, cardiogenic, septic, neurogenic, and anaphylactic: Main types
of shock
3. cardiogenic, hypovolemic, anaphylactic, neurogenic, and septic: CHANS
4. decrease in circulating blood volume. Deprives cells from oxygen resulting
in inadequate tissue perfusion and hypoxia: Hypovolemic Shock
5. most common cause: acute blood loss from trauma, fluid loss from burns,
severe diarrhea/vomiting: Causes of hypovolemic shock
6. subtle changes in vitals signs, anxiety, restlessness, delayed cap. refill, and
increased respiratory rate: Symptoms of hypovolemic shock
7. correct circulating blood volume and identify and treat the cause of the
volume loss. Watch for hypokalemia after large volume fluid replacement.: -
treatment for hypovolemic shock
8. hypotension, cellular hypoxia, and inadequate tissue perfusion. Resulting
from decreased cardiac output (heart is the cause): Cardiogenic shock
9. early sign: tachycardia: symptoms of cardiogenic shock
10. inflammatory cascade of events.: septic shock
11. caused by endotoxins released from bacteria within the body that results
in hypotension, hypo perfusion, and hypoxia. increased risk with age: cause
of septic shock
12. warm flushed skin, fever above 100.4, mild tachycardia, resp rate above
20, WBC count lower than 4,000 or grater than 10,000: early symptoms of septic
shock
13. client may seem anxious, high fever, neurological changes occur: as sepsis
progresses...
14. find and treat cause. IV antibiotics, fluid resuscitation, vasopressors, and
supplemental oxygenation. Surgical: incision to expose source: treatment of
septic shock
15. results in hypotension, bradycardia, low perfusion, and hypoxia to body
tissues as a result of the interruption of the sympathetic nervous system
response. all vitals are low.: Neurogenic Shock
16. flaccidity and paralysis below the level of injury, loss of bowel and bladder
control, loss of reflex activity, abnormal increase or absence of sweating below
the level of injury: symptoms of neurogenic shock
17. monitor vital signs for evidence of worsening or improving status, ensure
stability of the client's neck and back during position changes: Nursing man-
agement of neurogenic shock
18. occurs when the body reacts to a foreign substance: Anaphylactic Shock
19. penicillin. can lead to death: Anaphylactic shock- high risk

, PN3 exam 3
20. get EPI administered asap, establish IV site, monitor VS, attend to ABC's,
start cardiac monitoring: anaphylactic shock nursing management
21. bronchoconstriction with wheezing, chest pain, arrhythmias, severe hy-
potension. itching, hives, nasal congestion: symptoms of anaphylactic shock
22. trendelenburg: blood to the heart and brain--> feet higher than the heart: -
Shock position
23. administer epinephrin, then antihistamines and corticosteroids--> open
airway, stop histamine response, stops inflammation response.--don't need
parental consent to bring child in: medical-surgical management of anaphylactic
shock
24. toxins allowed to circulate freely in brain (ammonia) producing hepatic
encephalopathy: Cirrhosis
25. chronic alcohol abuse: Most common causes of cirrhosis
26. lactulose: treatment for cirrhosis
27. replacement of liver tissue by scar tissue: cirrhosis of the liver
28. fatigue, weight loss, bleeding easily, jaundice, confusion (build up of waste
body/brain), ascites (water around belly): cirrhosis S&S
29. alcohol avoidance, low protein diet, lactulose promotes ammonia excretion
through GI tract, abdominal paracentesis to relieve pressure from fluid of
ascites: cirrhosis treatment
30. bag to get water off the liver. Diagnosis purposes is to relieve ascites and
fluid. Therapeutic abdominal tap: abdominal paracentesis
31. swollen, fragile blood vessels in the esophagus. When varies hemorrhage,
it is a medical emergency associated with high mortality (people can choke
on their own blood): esophageal varices
32. chronic progressive disease= nerve cells that make dopamine are de-
stroyed. Without dopamine nerve cells cannot properly send messages and
it leads to loss of muscle function: Parkinson's Disease
33. bradykinesia, tremors, limbs and trunk become rigid, severe tremors
(pill-rolling): Parkinson's Disease S&S
34. carbidopa/levodopa--> aka sinamite (increases supply of dopamine to
brain) helps control symptoms. high-calorie, low protein diet.: Parkinson's Dis-
ease treatment
35. handle threats to public health (disasters, disease outbreaks, chemical
warfare, manage national stockpile (stockpile of meds for mass tragedy): -
Functions of CDC
36. early s&s: nausea, vomiting, diarrhea.
later s&s: immunosuppressive disorders: Radiation exposure
