Q: Which formula would you use to calculate pulse deficit if the apical pulse is 90 bpm and the radial pulse is 80 bpm?

Pulse deficit $$= \text{Apical pulse} - \text{Radial pulse}$$ $$= 90 - 80 = 10$$

Question 1

Which of the following best describes the clinical significance of auscultating the carotid arteries before palpating them during a cardiovascular assessment?

Accepted Answer

It prevents the risk of inducing a carotid sinus reflex, which can cause bradycardia or syncope.

Question 2

A patient presents with paroxysmal nocturnal dyspnea (PND). Which underlying cardiac condition is most likely associated with this symptom?

Accepted Answer

Left-sided heart failure

Question 3

During auscultation, you hear a split S2 sound at the end of inspiration in the pulmonic area. What is the physiological explanation for this finding?

Accepted Answer

Delayed closure of the pulmonic valve due to increased venous return during inspiration

Question 4

Which formula would you use to calculate pulse deficit if the apical pulse is 90 bpm and the radial pulse is 80 bpm?

Accepted Answer

Pulse deficit $$= 	ext{Apical pulse} - 	ext{Radial pulse}$$ 
$$= 90 - 80 = 10$$

Question 5

Which heart sound is louder at the base of the heart and what does it represent?

Accepted Answer

S2, representing closure of the semilunar valves

Question 6

A grade IV heart murmur is described as:

Accepted Answer

Loud with a palpable thrill

Question 7

Which of the following is a reliable indicator of central venous pressure (CVP) during neck vessel inspection?

Accepted Answer

Internal jugular vein

Question 8

In infants, the apical impulse is best palpated at which location?

Accepted Answer

4th intercostal space lateral to the midclavicular line

Question 9

A pregnant patient in her second trimester is likely to experience which cardiovascular change?

Accepted Answer

Decrease in blood pressure

Question 10

Which of the following is a common finding in older adults during cardiovascular assessment?

Accepted Answer

Gradual increase in systolic blood pressure

Question 11

When assessing the precordium, which sequence is recommended for a regional cardiovascular assessment?

Accepted Answer

Pulse and blood pressure, extremities, neck vessels, precordium

Question 12

Which of the following best describes an innocent murmur in children?

Accepted Answer

A murmur with no valvular or pathologic cause

Question 13

During auscultation, which area is best for listening to the mitral valve?

Accepted Answer

5th intercostal space at the left midclavicular line

Question 14

A patient is found to have a mid-systolic click during auscultation. This finding is most likely associated with:

Accepted Answer

Mitral valve prolapse

Question 15

Which of the following is a plausible explanation for a pulse deficit?

Accepted Answer

Some heartbeats do not result in a palpable pulse at the radial artery

Question 16

Which of the following is NOT a recommended position for auscultating abnormal heart sounds?

Accepted Answer

Standing upright

Question 17

Which developmental consideration is unique to infants regarding cardiovascular assessment?

Accepted Answer

Fetal shunts close within 10-15 hours after birth

Question 18

Which of the following best describes the pattern of a crescendo murmur?

Accepted Answer

Intensity increases throughout the murmur

Question 19

Which equation would you use to estimate cardiac output if stroke volume is 70 mL and heart rate is 75 bpm?

Accepted Answer

Cardiac output $$= 	ext{Stroke volume} 	imes 	ext{Heart rate}$$ 
$$= 70 	imes 75 = 5250 mL/$$min
