NSG-3130 EXAM 4
NSG 3130 Exam 4 | Questions and
Answers | 2026 Update with complete
solutions
Components of the heart - correct answer-the
pump
the electrical system
the vascular system
the blood volume
serum lipid levels - correct answer-fats can clog
blood vessels and decrease blood flow. LDL
should be less than 130. HDL greater than 45
males, 55 females. total cholesterol lower than
200. Triglycerides less than 160 males, females
135 or less.
Serum Electrolytes - correct answer-can affect the
conduction of the heart
,Hemoglobin - correct answer-An iron-containing
protein in red blood cells that reversibly binds
oxygen.
Creatinine kinase and troponin - correct answer-is
elevated with cardiac cell death. usually indicates
an MI
Preload - correct answer-amount of blood and
pressure in the ventricle at the end of diastole.
Increases due to increase of volume.
Afterload - correct answer-the resistance that has
to be exceeded for the ventricle to eject the blood
during systole. Increases due to HTN or
vasoconstriction.
cardiac output - correct answer-heart rate x stroke
volume
Lifespan considerations - correct answer--HR
goes down in older adults
-heart loses muscle tone which causes decrease
of cardiac output
-BP will trend up with age
-Irregularities in infants and children in common
, -atherosclerosis is the build up of plaque in the
vascular walls. more common in older adults
-HTN typically elevates in older populations
African American and hispanic populations -
correct answer-are more likely to develop chronic
HTN and heart diseases
Geriatric concerns - correct answer--blood vessels
are less elastic
-impaired valves due to stiffness causing a
decrease in CO
-Decreased baroreceptor response
Non-modifiable risk factors - correct answer-age,
race, family, gender ethnicity
Modifiable risk factors - correct answer-lifestyle,
diseases, and stress
metabolic syndrome - correct answer-A syndrome
marked by the presence of usually three or more
of a group of factors:
-central obesity
-increased triglycerides
-elevated cholesterol levels
