Shock Questions
Fever might not occur in those that have -----. - ANS immunosuppression
Explain the Blood flow of the heart and the rest of the body - ANS Right side of the heart pumps
blood to the alveoli of the lungs to get oxygenated.
Left side of the heart pumps blood to the rest of the body.
The cells pick up oxygen from the blood.
Where does oxygen bind to? - ANS Hemoglobin (hgb)
**What DOES the pulse oximeter measure and what does pulse oximeter NOT measure?** - ANS
The pulse oximeter measures the percent of oxygen bound to hemoglobin
The pulse oximeter does not measure the level of hemoglobin or ability of cell to take up or utilize
oxygen**
____can have a high O2 sat and a very low Hgb resulting in hypoxemia/anoxia. - ANS Anemia
____can have a high O2 sat but oxygen is either not released at the cell or cells do not accept
oxygen. - ANS Carbon Monoxide Poisoning
Other than anemia, ___can result in hypoxemia/anoxia. - ANS Sepsis
Carbon monoxide in the system........(finish the sentence) hint: relates to O2 - ANS does not release
oxygen for the cells to use.
T/F: O2 Sat is reliable in shock patients. - ANS FALSE
What is Cardiac Output?*** - ANS amount of blood pumped by the heart each minute.
,CO=SVxHR (important to know for shock)***
Normal level for cardiac output - ANS 4-6 L/min (normal range for adults)-amt of volume
What is Stroke Volume? - ANS amount of blood ejected with each contraction of the left ventricle.
What is Shock? - ANS A life-threatening circulatory failure with inadequate delivery of oxygen to
cells, or inadequate cellular oxygen utilization, leading to cellular and tissue hypoxia and necrosis.
What are the two most common type of shock? - ANS 1. Distributive
2. Hypovolemic
Shock commoly presents as hypotension of SBP ----- or MAP -----*** - ANS SBP <90*** or MAP
<65***
A nursing student is reviewing the categories of shock with her preceptor. Which of the student's
following choices shows an understanding of the topic? (SATA)
a. Cardiogenic shock
b. Hypervolemic shock
c. Obstructive shock
d. DVT shock
e. Hypovolemic shock
f. Distributive shock
g. Gastrointestinal shock - ANS a. Cardiogenic shock
c. Obstructive shock
e. Hypovolemic shock
f. Distributive shock
, What is Distributive shock? - ANS Peripheral vasodilation which increases capillary permeability.
A nurse is discussing the types of distributive shock with a new nurse. Which types should the new
nurse keep in mind? (SATA)
a. Brady shock
b.Sepsis shock
c. Pneumonia
d. Systemic Inflammatory Response Syndrome (SIRS)
e. Endocrine shock - ANS b. Sepsis shock
d. Systemic Inflammatory Response Syndrome (SIRS)
e. Endocrine shock
Septic shock: caused by? What is it? Lactate level? Mortality rate? - ANS - Caused by sepsis (systemic
infection of the blood)
- Severe circulatory, cellular and metabolic abnormalities leading to inadequate tissue perfusion
- Results in hypotension and elevated lactate level (lactate normal range: >2 mmol/L
- Mortality rate 40 - 50% ***
Systemic Inflammatory Response Syndrome (SIRS)? causes? - ANS - Intense inflammatory response
of the immune system
- caused by pathogens (believed to occur with covid-19 virus)
- can also be caused by burns, embolism, pancreatitis, anaphylaxis
