Which of these is true regarding S1?
a. occurs with the closure of the AV valves
b. occurs with the closure of the semilunar valves
c. is usually a silent event
d. is indicative of CHF ✅A
S1 occurs with the closure of the AV valves and signals the start of systole
S1 is loudest at the:
a. base
b. apex ✅B
S1 is heard loudest at the apex of the heart
Which of these is true regarding S2?
a. occurs with the closure of the AV valves
b. occurs with the closure of the semilunar valves
c. is usually a silent event
d. is indicative of an MI ✅B
S2 occurs with the closure of the semilunar valves and signals the end of systole
S1 signifies the __ wave of JVP
a. A wave
b. B wave
c. C wave
d. D wave ✅C
S1 is represented by the C wave of the JVP
S2 is loudest at the:
a. base
b. apex ✅A
S2 is heard loudest at the base of the heart
When auscultating, you hear audible S3 noises. What do these noises represent?
a. atrial gallop
b. ventricular gallop
c. tachycardia
d. bradycardia ✅B
S3 is usually a silent event that occurs with ventricular filling. An audible S3 noise
represents a ventricular gallop.
When assessing an athlete, you hear S3 sounds. What does this mean?
a. the patient may have CAD
,b. the patient may have CHF
c. the patient has a heart murmur
d. this is a normal finding ✅D
Although S3 sounds in older adults can represent CHF (congestive heart failure), an
audible S3 sound in an athlete is a normal finding
When assessing an older patient, you hear S4 sounds. What does this mean?
a. the patient may have CAD
b. the patient may have CHF
c. the patient has a heart murmur
d. this is a normal finding ✅A
Audible S4 sounds in an older person may represent CAD (coronary artery disease)
Blood volume usually increases by _______ % during pregnancy, with the most rapid
expansion during the second trimester. ✅30-40%

apex of the heart?

at/around the 4th intercostal space.
What are normal age-related changes that occur with an older person's CV system?
(Select all that apply)
a. increases systolic blood pressure
b. increased pulse pressure
c. thickening of left ventricle

When palpating the carotid arteries, what is the correct method?
a. palpate the carotid arteries one at a time
b. apply firm pressure to ensure you are feeling the correct pulse
c. palpate both arteries simultaneous to have a more accurate assessment of bilateral

Lightly palpate one carotid artery at a time to prevent cutting off blood flow
, When auscultating a patient's carotid pulse, you hear a rapid, swooshing turbulence.
What is this called?
a. ronchi
b. bruit
c. thready pulse
d. murmur ✅B
That noise is called bruit, which indicates a LOCAL vascular cause
Why is the absence of bruit not necessarily reflective of a patient being free from an
artery obstruction? ✅Once an artery is 2/3 occluded, the bruit becomes significantly
quieter. When is is fully occluded, bruit disappears.
What does a carotid sinus hypersensitivity lead to? (Select all that apply)
a. leads to decreased HR
b. leads to increase HR
c. leads to decreased BP
d. leads to increased BP ✅A, C
Carotid sinus hypersensitivity leads to decreased heart rate and blood pressure, as well
as syncope and ischemia.
