Shock Flashcards
(32 cards)
What does hypovolemic mean?
A loss in fluid
Categories of shock?
Hypovolemic, distribution and cardio genie
What is distributive shock mean?
Loss of vascular tone
Which shock is due to sepsis?
Distributive shock
What is cardiogenic shock?
Due to a Heart pump failure
If hypovolemic shock is suspected, what is a nursing intervention?
Monitor vitals, ECG, and pulse ox
Signs of early compensated shock include?
Tachycardia, poor skin color, cool /dry skin, and delayed capillary refill.
Aside from sepsis, what other causes of distributive shock?
Anaphylaxis , toxic chemicals, or spinal cord injury.
What does high blood pressure mean?
Is the force of the blood against your artery walls is high enough that it may eventually cause health problems, such as heart disease.
HTN signs and symptoms? select all that apply
a. Nosebleeds
b. SOB
c. diarrhea
d. HA
a, b, and d.
Headaches, shortness of breath, or nosebleeds, but these signs and symptoms aren’t specific and usually don’t occur until high blood pressure has reached a severe or life-threatening stage.
Complications of HTN, and isn’t resolved?
Heart attack or stroke. High blood pressure can cause hardening and thickening of the arteries (atherosclerosis), which can lead to a heart attack, stroke or other complications.
What is the number reading for hypotension?
a. 90mmHg
b. 80 mmHg
c. 60 mmHg
d. 75 mmHg
a. A blood pressure reading lower than 90 mmHg for the top number (systolic)
C, for 60 mm Hg for the bottom number (diastolic) is generally considered low blood pressure.
True or false.
The cause of hypotension can be d/t dehydration, large amounts of blood loss through injury, and a state of shock.
Can be from as low as dehydration to higher (medical conditions)
Ex. Losing blood, sepsis, lack of nutrition, allergic reaction, or heart problems
Extreme hypotension leads to shock, what are the signs and symptoms of that you will see as a result of shock? select all that apply.
a. Rapid and shallow breathing
b. pale skin
c. confusion
d. strong and slow pulse
e. cool and clammy skin
answer: A, B, C, E
Extreme hypotension can result in this life-threatening condition. Signs and symptoms include:
Confusion, especially in older people
Cold, clammy, pale skin
Rapid, shallow breathing
Weak and rapid pulse
Signs & symptoms of hypotension?
select all that apply
a. fatigue
b. dizziness
c. Nausea
d. LOC
e. Blurry vision
S/Sx:
Dizziness or lightheadedness Fainting Blurred or fading vision Nausea Fatigue Lack of concentration
How many stages of shock?
a. 4- Initial, compensatory, impressive, and refractory.
b. 5- Initial, refractory, compensatory, progressive, and recovery.
c. 3- Initial, progressive, and recovery
d. 2- initial and compensatory
There are 4 stages of shock. Initial, compensatory, impressive, and refractory.
During the initial stage of shock, the body is the demand for oxygen is increasing. What will you start to see change?
a. metabolic changes from aerobic to anaerobic in order to get oxygen to the cells.
b. overcome increasing consequences of anaerobic metabolism to maintain homeostasis
c. impaired GI motility
a. metabolic changes, at the cellular level. Lactic acid builds up and must be removed by the liver:
• The body makes lactic acid when it is low in the oxygen it needs to convert glucose into energy. Lactic acid buildup can result in muscle pain, cramps, and muscular fatigue
b and c, are in the compensatory stage of shock.
The baroreceptors in the caratoid and aortic body will activate the SNS in response to decrease blood pressure occurring d/t what?
a. respiratory depression
b. lactic acid builds up
c. oxygen demand from the ANS
d. volume loss
d. d/t volume loss, the heart, and the brain will make attempts to overcome the infection, then induces vasoconstriction to maintain perfusion.
O2 demand is also happening but in the SNS, NOT ANS, RESULTING in V/Q MISMATCH.
Things that are mportant for nurses need to prevent sepsis? select all that apply.
a. increase in Na+ intake
b. start antibiotic therapy
c. fluid resuscitation
d. give vasopressin (if necessary)
o Start antibiotic early
o Fluid resuscitation
o Give vasopressin (if necessary)
True or false.
the decrease in blood to the kidneys inactivates the RAAS SYSTEM.
False. the RAAS system activates because it essential for the regulation of blood pressure and fluid balance.
primarily it is regulated by the rate of renal blood flow.
True or False.
In stage 3 of progressive shock stage, organs are starting to fail.
True.
The cardiac output begins to decrease= ↓ blood pressure
what is the importance of both cardiac output and cardiac index?
a. a decreased in tissue perfusion and impaired cellular metabolism
b. cardiac output is s determined by stroke volume. And the cardiac index is a marker of how well the heart is functioning.
c. cardiac output is the volume of blood the heart pumps out per min. Cardiac Index is an assessment of the cardiac output (relating to the heart’s performance).
d. coagulation and hemodynamic dysfunction
important to let us know if a patient’s heart is pumping enough blood and delivering enough oxygen to cells.
although for “B”, is true about the cardiac index, the cardiac output is not only determined by stroke volume, it is also a combination of stroke volume & heart rate
How is stroke volume determined?
a. BP
b. Preload, afterload and contractility
c. Preload and afterload
d. Contractility and BP
It is determined by Preload, contractility and afterload.
what is shock characterized as?
it is a decrease in tissue perfusion and impaired cellular metabolism.
