NSG3160 | NSG3160 Health Assessment Exam 2
Version 1 | Questions with Correct Answers and
Expert Explanation for Each Question | Galen
1. When auscultating the heart, the nurse identifies the S1 sound. Which physiological
event is primarily responsible for this sound?
A. Closure of the semilunar valves
B. Opening of the aortic valve
C. Closure of the atrioventricular valves
D. Filling of the ventricles during diastole
Correct Answer: C
Expert Explanation: The S1 heart sound, often described as ‘lub,’ marks the
beginning of systole. It is caused by the closure of the mitral and tricuspid valves to
prevent backflow into the atria. This sound is usually loudest at the apex of the
heart. The nurse should synchronize this sound with the carotid pulse for accuracy.
Understanding the cardiac cycle helps the nurse distinguish between normal and
abnormal findings.
2. A nurse is assessing a patient for jugular venous distention (JVD). At what angle
should the head of the bed be positioned?
A. 90 degrees (High Fowler’s)
,B. 0 degrees (Flat)
C. 60 degrees
D. 30 to 45 degrees
Correct Answer: D
Expert Explanation: JVD assessment is most accurate when the patient is in a semi-
Fowler’s position. The 30 to 45-degree angle allows for the visualization of the
internal jugular vein’s pulsation relative to the sternal angle. If the patient is flat, the
veins may appear distended even in healthy individuals. If the patient is upright, the
vein may collapse and hide important clinical data. Consistent positioning ensures
reliable monitoring of central venous pressure.
3. The nurse notes a ‘thrill’ while palpating the patient’s precordium. What does this
finding indicate?
A. A normal heart contraction
B. Fluid accumulation in the pericardial sac
C. A palpable vibration signaling a loud murmur
D. An expected finding in a thin patient
Correct Answer: C
,Expert Explanation: A thrill is a fine, rushing vibration felt over the precordium or
an artery. It is generally associated with turbulent blood flow and indicates a
significant heart murmur, usually grade IV or higher. During palpation, the nurse
should use the palmar surface of the hand to detect this. Finding a thrill requires
further auscultation to characterize the associated murmur. This abnormality often
suggests underlying valvular disease or structural defects.
4. Where is the best anatomical location to auscultate the mitral valve?
A. Second intercostal space, right sternal border
B. Fourth intercostal space, left sternal border
C. Second intercostal space, left sternal border
D. Fifth intercostal space, left midclavicular line
Correct Answer: D
Expert Explanation: The mitral valve area is located at the apex of the heart.
Specifically, this is found at the fifth intercostal space along the left midclavicular
line. This site is also where the point of maximal impulse (PMI) is typically palpated.
Auscultating here allows the nurse to hear S1 more clearly than S2. Proper
identification of this site is crucial for accurate heart rate measurement and murmur
detection.
, 5. During a physical exam, the nurse uses the bell of the stethoscope to listen to the
carotid arteries. What is the nurse assessing for?
A. A thrill
B. A bruit
C. Normal S2 sounds
D. Pulse deficit
Correct Answer: B
Expert Explanation: The bell of the stethoscope is used to pick up low-pitched
sounds like bruits. A bruit is a blowing or swishing sound indicating turbulent blood
flow, often due to narrowing or plaque. Patients should be asked to hold their breath
briefly during this assessment to avoid lung sound interference. Auscultating for
bruits is an essential step in identifying potential stroke risks. Normal carotid
assessment should yield no audible sounds.
6. A patient has a pulse that is easily palpable but can be obliterated with firm
pressure. How should the nurse document this pulse grade?
A. 1+
B. 4+
C. 3+
