NSG 3160- EXAM 3 QUESTIONS AND CORRECT
VERIFIED ANSWERS) ALREADY GRADED A
_____ Tough, fibrous, double-walled sac that surrounds and
protects the heart
_____ Thin layer of endothelial tissue that lines the inner
surface of the heart chambers and valves
_____ Reservoir for holding blood
_____ Ensures smooth, friction-free movement of the heart
muscle
_____ Muscular pumping chamber
_____ Muscular wall of the heart
a. Pericardial fluid
b. Ventricle
c. Endocardium
d. Myocardium
e. Pericardium
f. Atrium - correct answer- __E___ Tough, fibrous,
double-walled sac that surrounds and protects the heart
__C___ Thin layer of endothelial tissue that lines the inner
surface of the heart chambers and valves
,__F___ Reservoir for holding blood
_A____ Ensures smooth, friction-free movement of the heart
muscle
__B___ Muscular pumping chamber
__D___ Muscular wall of the heart
•Decreased vital capacity: - correct answer- maximum
amount of air that a person can expel from the lungs after first
filling the lungs to the maximum
•age related changes result in an increase in small airway
closure.
•First seven ribs attach to sternum by - correct answer-
costal cartilages. 8,9,10 attached to costal cartilage, ribs 11 and
12 are "floating" with free palpable tips
12th rib - correct answer- palpate midway b/w the spine
& the patient's side to identify the free tip
A bruit heard while auscultating the carotid artery of a 65-year-
old patient is caused by:
decreased velocity of blood flow through the carotid artery.
,turbulent blood flow through the carotid artery.
rapid blood flow through the carotid artery.
increased viscosity of blood. - correct answer- turbulent
blood flow through the carotid artery.
A carotid bruit is a blowing, swishing sound indicating blood flow
turbulence. A bruit indicates atherosclerotic narrowing of the
vessel.
A murmur is heard after S1 and before S2. This murmur would
be classified as:
a. Diastolic (possibly benign)
b. Diastolic (always pathologic)
c. Systolic (possibly benign)
d. Systolic (always pathologic) - correct answer- c.
Systolic (possibly benign)
abnormal chest findings - correct answer- -increased
chest size/altered contour >90 degrees
-unequal chest expansion
-abnormal breathing pattern
-use of accessory muscle to breathe (tripod stance)
, -nasal flaring
-greater or lower than 12-20 respirations per minute
-clubbing of distal phalanx occurs with COPD or chronic hypoxia
acute bronchitis - correct answer- an inflammation of
the lower respiratory tract that is usually due to infection. sore
throat, low-grade fever, cough, no pain, resonance
predominates, no crackles
acute cough - correct answer- less than 2-3 weeks vs
chronic=last 2+ months
Acute heart failure - correct answer- following a
myocardial infarction, when contractibility has been damaged
aging adult - correct answer- costal cartilage more
calcified = thorax less mobile. •Respiratory muscle strength
DECLINES
•DECREASE in elastic properties equals less distensible &
lessening the tendency to collapse & recoil
•Aging lung is a more rigid structure that is harder to inflate
