NUR 505 Module 4-6 Questions with CORRECT
Answers (Grade A+)
Question 1:
atrioventricular valves: Tricuspid (Right)
Answer:
Anatomic Location:
Separates the right atrium from the right ventricle.
Function/Blood Flow:
S1 Valves close; stop back flow when AV shuts.
Auscultation Location:
Fourth left intercostal space along the lower left sternal boarder.
Question 2:
atrioventricular valves: Mitral
(Left)
Answer:
Anatomic Location:
Separates the left atrium from the left ventricle.
Function/Blood Flow:
S1 Valves close; stops during systole and opens during diastole
Auscultation Location:
the apex of the heart in the fifth left intercoastal space,
midclavicular line.
Question 3:
Semilunar Valves: Aortic (Left)
Answer:
Anatomic Location:
Lies Between the left ventricle and the aorta
Function/Blood Flow:
S2 valves close
Auscultation Location:
Fourth left intercostal space along the lower left sternal boarder.
,Question 4:
Semilunar Valves: Pulmonic
(Right)
Answer:
Anatomic Location:
Separates the right ventricle from the pulmonary artery
Function/Blood Flow:
S2Valves close
Auscultation Location:
Second left intercostal space along the lower left sternal
boarder.
Question 5:
Contraction of the ventricles (systole) opens semilunar
valves cause blood rush to
the pulmonary artery and aorta, when ventriculus relax who
occurs?
Answer:
diastole happens and the valves close shutting off back blood
flow.
Question 6:
S3 - ventricular feel -
Answer:
- aorta contracts to ensure ejection of blood
,Question 7:
What are some differences in
an infants heart function?
Answer:
Fetal circulation compensates for the nonfunctional fetal
lungs.
Blood flows from the right atrium into the left atrium via the
foramen ovale (RA - foramen ovale - LA)
The right ventricle pumps blood through the patent ductus
arteriosus rather than into the lungs ( RV - patent ductus
arteriosus NO lungs)
The right and left ventricles are equal in weight and muscle
mass because they both pump blood into the systemic circulation.
Question 8:
What are some differences in a
children heart function?
Answer:
Bye age ONE, the relative sizes of the left and right ventricles
approximately the adult ratio 2:1
The heart lies more horizontally in the chest in infants and
young children compared to adults.
the apex of the heart rides higher, 4th intercostal space
The adult heart position is reached by age 7 - by this age it's
in the same location as the average adult.
Question 9:
What are some differences in
Pregnancy heart function?
Answer:
Blood volume increases
Workload of the heart is increased due to increased HR and
stroke volume (high bp sometimes)
Returns to normal 3-4 weeks after delivery
, Question 10:
What are some differences in
Elderly heart function?
Answer:
Heart size may decrease (If HTN or HD is not present)
LV wall thickens, valves fibrose
SV decreases
Question 11:
What happens in an infant's
heart after birth?
Answer:
Closure of ductus arteriosus in 24-48 hours.
The functional closure of the interatrial foramen ovale as pressure rises in the left atrium.
The mass of the left ventricle increases after birth in response
to the left ventricle assuming responsibility for systemic circulation.
Question 12:
What are some more changes
to occur in the elderly population?
Answer:
Heart size may decrease - if no comorbidities like HTN or HD
because they will increase the size.
The left ventricular wall thickness, and the valves tend to fibrose and calcify.
Stroke volume decreases, and cardiac output during exercise
declines by 30-40%
The endocardium thickens
The myocardium becomes less elastic and more rigid so that
recovery of the myocardial contractility is delayed.
The response to stress and increased oxygen demand is less
efficient.
