PNP301 - Test 3 Questions With Correct
Answers
What is shock? - CORRECT ANSWER✔✔-Widespread abnormal cellular
| | | | | | | |
metabolism that occurs when the human need for oxygenation and tissue
| | | | | | | | | | |
perfusion is not met to the level needed to maintain cell function.
| | | | | | | | | | |
What is tissue perfusion? - CORRECT ANSWER✔✔-blood flow through body
| | | | | | | | | |
tissues
What is shock the result of? - CORRECT ANSWER✔✔-decreased circulating blood
| | | | | | | | | | |
volume leading to decreased tissue perfusion and general hypoxia
| | | | | | | |
Why is shock considered a syndrome? - CORRECT ANSWER✔✔-Identified through
| | | | | | | | |
S&S
|
Because the cellular, tissue, and organ events that occur in response to its
| | | | | | | | | | | | |
presence happen in a predictable sequence.
| | | | |
What type of response is usually triggered when someone goes into shock? -
| | | | | | | | | | | | |
CORRECT ANSWER✔✔-whole-body
|
What are main initial manifestations of shock? (2) - CORRECT ANSWER✔✔--
| | | | | | | | | | |
hypotension
,- anaerobic cellular metabolism
| | |
What is hypovalemic shock? - CORRECT ANSWER✔✔-extensive loss of blood/
| | | | | | | | | |
fluid volume
|
What commonly causes hypovalemic shock? - CORRECT ANSWER✔✔-Commonly
| | | | | | | |
caused by hemorrhage (external or internal) and dehydration (diarrhea/vomiting)
| | | | | | | |
What is cardiogenic shock? - CORRECT ANSWER✔✔-Occurs when the heart is
| | | | | | | | | | |
damaged and unable to supply sufficient blood to the body
| | | | | | | | |
What is vasogenic shock? - CORRECT ANSWER✔✔-caused by sepsis, deep
| | | | | | | | | |
anesthesia, or anaphylaxis | |
circulatory failure resulting from vasodilation
| | | |
What is sepsis? - CORRECT ANSWER✔✔-- systemic inflammatory response to
| | | | | | | | | |
documented or suspected infection | | |
- presence of tissue perfusion abnormalities
| | | | |
What is anaphylaxis? - CORRECT ANSWER✔✔--Severe allergic reaction
| | | | | | |
- Massive vasodilation
| |
- Increased capillary permeability
| | |
,What are clinical manifestations of anaphylaxis? - CORRECT ANSWER✔✔--
| | | | | | | | |
Anxiety, confusion, dizziness
| |
- Sense of impending doom
| | | |
- Chest pain
| |
- Incontinence
|
- Swelling of the lips and tongue, angioedema
| | | | | | |
- wheezing
| |
- respiratory distress and circulatory failure
| | | | |
What is neurogenic shock? - CORRECT ANSWER✔✔-Hemodynamic phenomenon
| | | | | | | |
that can occur within 30 minutes of a spinal cord injury at the fifth thoracic (T5)
| | | | | | | | | | | | | | | |
vertebra or above and can last up to 6 weeks.
| | | | | | | | |
- spinal cord injury
| | | |
- opiod overdose
| |
Sequence of Neurogenic Shock - CORRECT ANSWER✔✔-- loss of sympathetic
| | | | | | | | | |
tone |
- venous and arterial vasodilation
| | | |
- decreased BP
| |
- decreased venous return
| | |
- decreased stroke volume
| | | |
- decreased cardiac output
| | | |
- decreased cellular oxgen supply
| | | | |
, - decreased tissue perfusion
| | |
- impaired cellular metabolism
| | |
What is poikilothermia? - CORRECT ANSWER✔✔-inability to regulate body
| | | | | | | | |
temperature
taking on the temperature of the environment
| | | | | |
Stages of Circulatory Shock - CORRECT ANSWER✔✔-1) compensatory
| | | | | | | |
2) progressive
| |
3) decompensated/refractory
|
What is the difference between relative and absolute hypovalemia? - CORRECT
| | | | | | | | | | |
ANSWER✔✔-absolute = reduction in total circulating blood volume | | | | | | | |
relative = decrease in the effective circulating blood volume (ex sepsis)
| | | | | | | | | |
What are the precipitating factors of cardiogenic shock? - CORRECT
| | | | | | | | | |
ANSWER✔✔-- Myocardial infarction | | |
- Cardiomyopathy
|
- Blunt cardiac injury
| | |
- Severe systemic or pulmonary hypertension
| | | | |
- Cardiac tamponade
| |
- Myocardial depression from metabolic problems
| | | | |
