NUR 170 Exam 2 Questions And Answers.
Updated And Verified.
What is perfusion? - Answer✔the cardiovascular and pulmonary systems providing a supply of
oxygenated blood to every cell in the body, and this requires the to generate sufficient cardiac
output to transfer the blood through the body to be distributed in the tissues throughout the body
What does impaired infusion do? - Answer✔cause tissue damnage such as ischemia or necrossis
What is ischemia? - Answer✔decrease blood/oxygen supply to a tissue, which can lead to a
blockage and then a ♡ attack
What is necrosis? - Answer✔tissue death from lack of blood supply
What is central perfusion? - Answer✔Generated by cardiac output- the amount of blood pumped
by the heart each minute
propels blood to organs and their tissues
systemic
What is a normal cardiac output? - Answer✔4-8 L/min
What happens when cardiac output is low? - Answer✔Thins are not getting enough blood that is
needed to do things such as walking to the bathroom, and will cause your body tow rok harder
and be out of breath
What is tissue perfusion? - Answer✔Volume of blood that flows through tissues, supplied by
blood flow from arteries to cappilaries, and the amount of blood varies by organs
How do you differentiate tissue perfision? - Answer✔a clot in the renal artery is tissue perfusion,
not the kidney as a whole is inpaired, the renal artery is interrupting the kidney as a whole
What are some assessment findings of impaired central perfusion? - Answer✔-hypotension
(decreased blood pressure less than 90/60) and at this level it can affect the blood flow of the
organs and people will start to feel side effects of low blood pressure
-tachycardia (increased heart rate, above 100 bpm)

-change in mental status
-shortness of breath
-peripheral edema
-change in heart rhythm
-diaphoresis (sweating) or anxiety
What are the S1 and S2 sounds? - Answer✔Every apical pulse is a combination two sounds,
defined as S1 and S2. The S1 is the low-pitched, dull sound ("lub") heard when the tricuspid and
mitral valves close as ventricular filling ends. The S2 is the higher pitched, shorter sound ("dub")
heard when the pulmonic and aortic valves close at the end of ventricular ejection.
What are some assessment findings of impaired tissue perfusion? - Answer✔-pale, cool skin
-less hair on legs
-diminished dorsalis pedis and posterior tibial pulses
-slowed capillary refill (supposed to be less than 3 seconds
-decreased urine output
-can affect brain depends of extent of ischemia
What are some non-modifiable risk factors of impaired perfusion? - Answer✔-older adults
because of anatomical changes such as sclerosis (hardening of the skin)
-men more at tirsk until women hit menopause (estorgen is gone, and that protects the heart)
(men presented more textbook while women are often overlooked)

-race (African-Americans can have more severe hypertension and are at higher risk for heart
disease)
-genertics, heredity, family history
What are modifiable risk factors of impaired perfusion? - Answer✔-smoking
-high BP (increases the workload of the heart
-high blood cholesterol (increases risk for coronary artery disease
-physical inactivity (risk of diabetes and atherosclerosis)
-diabetes mellitus (risk of artherosclerosis and cardiovascular disease)
What are the numbers of obesity and overweight? - Answer✔obesity: BMI of 30 or above
overweight: BMI of 25 or above
What are contributing risk factors of impaired perfusion? - Answer✔-stress
-alcohol
-diet and nutrition
What does a blood pressure reading tell you? - Answer✔the systolic number measures the
pressure in your arteries when your heart beats while the diastolic number measures the pressure
in your arteries when your heart rests between beats
What does a chest X-Ray read? - Answer✔shows the heart, how big it is
What is total cholesterol? - Answer✔the total amount of cholesterol in your blood, should be less
than 200, and needs to be look at because you do not see symptoms and it can be a big risk factor
What is an ECG (electrocardiogram)? - Answer✔looks at the electrical activity, shows rhythm
you are in and can show only previous MI, not that you are about to have one
What is a stress test? - Answer✔to show how your heart work during physical activity
What is an exercise stress test? - Answer✔speeding the heart to check it during physical activity,
while someone watches you heart during it
