NUR 101/NUR101 Exam 2 V1 | Health Assessment
Q&A with Rationale | Fortis College
1. During a thoracic assessment, the nurse identifies the ‘Angle of Louis.’ Which of the
following is the clinical significance of this landmark?
A. It is the location where the carotid pulse is most easily palpated.
B. It marks the site of the bifurcation of the trachea into the right and left main bronchi.
C. It corresponds to the level of the fourth intercostal space.
D. It is the anatomical landmark used to locate the apex of the heart.
Correct Answer: B
Explanation: The Angle of Louis, or sternal angle, is the articulation of the manubrium and
the body of the sternum. It is continuous with the second rib and marks the site where the
trachea bifurcates into the bronchi. Identifying this landmark is essential for accurate rib
counting and auscultation.
2. When auscultating the lungs of a healthy adult, the nurse hears low-pitched, soft sounds
over the peripheral lung fields. How should the nurse document these sounds?
A. Bronchial breath sounds
B. Vesicular breath sounds
C. Bronchovesicular breath sounds
D. Adventitious breath sounds
,Correct Answer: B
Explanation: Vesicular breath sounds are normal sounds heard over most of the lung
fields, characterized by a soft, rustling quality. They are typically low-pitched and have an
inspiration phase that is longer than the expiration phase. Documentation of these sounds
indicates normal air movement in the smaller bronchioles and alveoli.
3. A nurse is assessing a patient with suspected lobar pneumonia. Which finding would the
nurse expect when performing tactile fremitus?
A. Increased fremitus over the affected area
B. Decreased fremitus over the affected area
C. Absent fremitus over the affected area
D. Normal fremitus throughout all lung fields
Correct Answer: A
Explanation: Tactile fremitus is the vibration felt on the chest wall when the patient
speaks. Increased fremitus occurs with compression or consolidation of lung tissue, such as
in lobar pneumonia, because sound travels better through solid or fluid-filled medium than
air. The nurse should use the palmar base or ulnar edge of the hand for this assessment.
4. The nurse is auscultating the heart at the left fifth intercostal space, midclavicular line.
Which heart sound is best heard in this area?
A. S2 at the Aortic area
B. S1 at the Mitral area
, C. S2 at the Pulmonic area
D. S1 at the Tricuspid area
Correct Answer: B
Explanation: The mitral area (apex of the heart) is located at the fifth intercostal space at
the left midclavicular line. S1, which signifies the closure of the atrioventricular valves, is
heard loudest at the apex. This is also the site where the apical pulse is assessed for one full
minute.
5. Which of the following descriptions best characterizes the S2 heart sound?
A. It is caused by the closure of the aortic and pulmonic valves.
B. It marks the beginning of systole.
C. It is caused by the closure of the mitral and tricuspid valves.
D. It is best heard at the apex of the heart.
Correct Answer: A
Explanation: The S2 heart sound, often described as ‘dub,’ is produced by the closure of
the semilunar valves (aortic and pulmonic) at the end of systole. It is loudest at the base of
the heart, specifically the second intercostal space. This sound marks the beginning of
diastole in the cardiac cycle.
