NURS 403 Week 4 Questions With
Complete Solutions
Hemodynamics concerns which 2 systems? correct answer: 1.
cardiovascular
2. pulmonary
What are hemodynamics? correct answer: The forces that
circulate blood through the body
What is hemodynamic monitoring? correct answer:
Measurement of pressure, flow, and oxygenation of blood within
the cardiovascular system
What are the 3 reasons that we do hemodynamic monitoring?
correct answer: 1. To allow for early detection, identification,
treatment
2. To evaluate response to treatment
3. Evaluation of cardiovascular function
What are the 3 goals of hemodynamic monitoring? correct
answer: 1. maitain adequate tissue perfusion
2. Alert health care team of cardiovascular crisis before organ
injury occurs
3. Evaluate response to treatment modalities
What are some types of non-invasive hemodynamic monitoring?
correct answer: o Blood pressure
,o HR, O2
o Cap refill
o Pulses
o Skin temperature
o Urine output
What are 2 types of invasive hemodynamic monitoring? correct
answer: 1. arterial blood pressure monitoring
2. central venous pressure monitoring
What is the other way that we classify types of hemodynamic
monitoring? correct answer: 1. continuous
2. intermittent
Hemodynamic monitoring can tell us about what 4 things?
correct answer: 1. vasular capacity
2. blood volume
3. pump effectiveness
4. tissue perfusion
- we rely on this information because there is no way to directly
measure organ flow
What are the 3 factors/measurements that make up
hemodynamics? correct answer: 1. cardiac output (HR x SV)
2. BP
3. central venous pressure/ pulmonary wedge pressure
What 3 things make up stroke volume? correct answer: 1.
preload
2. afterload
3. contractility
, What is cardiac index? correct answer: CI = CO/total body
surface area
- compares CO to SA
Heart rate can cause alteration in hemodynamics, what about
heart rhythm? correct answer: Yes- ex. dysrhythmias like afib
or flutter
- causes lack of synchronization
What is preload? correct answer: Volume of blood in a ventricle
before it contracts (pressure on ventricle walls)
How do we measure preload?
Explain this. correct answer: Central Venous Pressure (CVP)
also called Right Atrial Pressure (RAP)
- We cannot measure volumes, so instead, we measure the
pressure in the right atria
What are the 2 presures that relate to preload? correct answer:
1. Pulmonary artery occlusion pressure (PAOP) or Wedge
Pressure
2. Central Venous Pressure (CVP)/ Right Artial Pressure (RAP)
What is the normal value for PAOP/ wedge pressure?
CVP/RAP? correct answer: Wedge Pressure- 4-12 mmHg
CVP- 2-8 mmHg
Would would increased circulating volume like a bolus affect
preload? correct answer: Increase
