NURSING 201 EXAM 1
HYPERTENSION QUESTIONS AND
ANSWERS
HTN learning objectives - Correct Answers -Review normal physiology of BP
Review definition of perfusion and relationship with blood pressure (BP)
Review categories of HTN
Distinguish between primary and secondary hypertension
Identify risk factors for hypertension
Discuss treatment modalities for hypertension
Discuss complications of HTN
Discuss hypertensive crisis and treatment
Discuss nursing education of the patient with HTN
Definition of Perfusion - Correct Answers -Circulation of blood through tissues,
supplying cells with nutrients and oxygen and removal of cellular waste products
Requires: functioning cardio-respiratory system;(pump), adequate fluid volume (blood),
transportation mode clear from clots (arteries)
What are some attributes of perfusion? Nursing assessment?
What happens when cells are not perfused?
Nursing assessment
What is required for perfussion? - Correct Answers -Requires:
functioning cardio-respiratory system;(pump), adequate fluid volume (blood),
transportation mode clear from clots (arteries)
waste is Co2 (lungs), kidney and liver helps
What happens when cells are not perfused?
Nursing assessment - Correct Answers -decreased LOC
Demisished GI/ decrease BS
, decreased Urine output
Decreased cap refill
lactic acid builds up
What are some attributes of perfusion? Nursing assessment? - Correct Answers -color
of skin
cap refill good
LOC good
respirations normal
urine output
BP normal
GI moving and BS
Blood Pressure and Perfusion - Correct Answers -MAP(mean arterial pressure):
average pressure within the arterial system that is felt by the organs in the body
MAP=(SBP + 2DBP) / 3
MAP > 60 mm Hg needed to adequately sustain and perfuse vital organs. If not;
ischemia develops.
HTN develops when one or more of the BP regulating mechanisms are defective(affects
CO or SVR or both)
when does HTN develop? - Correct Answers -HTN develops when one or more of the
BP regulating mechanisms are defective(affects CO or SVR or both)
atherosclerosis affects BP
What is MAP and level needed? - Correct Answers -MAP(mean arterial pressure):
average pressure within the arterial system that is felt by the organs in the body
MAP=(SBP + 2DBP) / 3
MAP > 60 mm Hg needed to adequately sustain and perfuse vital organs. If not;
ischemia develops.
What factors are related to BP. What are these factors - Correct Answers -Blood
Pressure= Cardiac output X Systemic Vascular Resistance
Cardiac output determined by:
-HR
-Contractibilty
-conductivity
and renin fluid control
