Health Assessment Exam 3 NSG3160
Questions With Correct Answers|
Latest Update- Galen
**Q1: What is S1 and what causes the sound?**
**A)** Closure of semilunar valves
**B)** Closure of AV valves – "LUB" sound at the apex
**C)** Closure of the aortic valve
**D)** Rapid ventricular filling
**Correct Answer: B**
**Rationale:** S1 is the start of systole and serves as a reference point for timing of all cardiac sounds.
It is caused by the closure of the atrioventricular (AV) valves (mitral and tricuspid). The "LUB" sound is
best heard at the apex of the heart .

**Q2: What causes the sound of S2?**
,**A)** Closure of AV valves
**B)** Closure of semilunar valves – "DUB" at the base
**C)** Rapid ventricular filling
**D)** Atrial contraction
**Correct Answer: B**
**Rationale:** S2 is caused by the closure of the semilunar valves (aortic and pulmonic). The "DUB"
sound is best heard at the base of the heart. S2 marks the end of systole and the beginning of diastole .

**Q3: What are the locations of the heart valves for auscultation?**
**A)** Aortic: 2nd LICS, Pulmonic: 2nd RICS
**B)** Aortic: 2nd RICS, Pulmonic: 2nd LICS, Erb's: 3rd LICS, Tricuspid: LLSB, Mitral: 5th ICS MCL
**C)** Aortic: 5th ICS MCL, Mitral: 2nd RICS
**D)** All valves are heard at the apex
**Correct Answer: B**
**Rationale:** The correct auscultation locations are:
- **Aortic:** 2nd intercostal space, right sternal border
- **Pulmonic:** 2nd intercostal space, left sternal border
- **Erb's Point:** 3rd intercostal space, left sternal border
, - **Tricuspid:** Left lower sternal border (4th–5th ICS)
- **Mitral:** 5th intercostal space, left midclavicular line

**Q4: What is a murmur?**
**A)** Normal heart sound caused by valve closure
**B)** Turbulent blood flow in the heart – blowing, swooshing sound
**C)** Inflammation of the pericardium
**D)** Palpable vibration on the chest wall
**Correct Answer: B**
**Rationale:** A murmur occurs with turbulent blood flow in the heart. It is described as a blowing or
swooshing sound. Murmurs can be systolic, diastolic, or continuous and may indicate valve stenosis or
regurgitation .
---
**Q5: What is pericardial friction rub?**
**A)** Normal S1 sound
**B)** Inflammation of the pericardium – high-pitched, scratchy sound heard with diaphragm when
patient sits up
**C)** A type of murmur
**D)** Closure of the AV valves
