NR 509 APEA Test 3PQuestion 1
A 3 year-old presents with a history of fever and cough over the past 24 hours. Findings on exam reveal:
temperature of 102°F, apical heart rate of 157 beats/minute, and respiratory rate of 40 breaths/minute.
Tachypnea in this child is most likely related to
Paradoxical respirations.
the child's febrile state. Correct
the child's age.
an airway obstruction.
Explanation:
In children, heart and respiratory rates will increase with fever. For every degree of fever the respiratory
rate will increase 3-4 breaths/minutes and the heart rate will increase 8-10 beats/minute.
Question 2
Q) When percussing the lower posterior chest, begin by:
Correct: standing on the side rather than directly behind the
patient. having the patient lie supine on the examining table.
carefully palpating any area the patient has reported pain. using the
ball or the ulnar surface of the hand.
Explanation:
When percussing the lower posterior chest, stand on the side rather than directly behind the patient.
This position allows the ability to place the pleximeter finger more firmly on the chest and the plexor is
more effective in making a better percussion note. If the patient is lying supine, the posterior chest will
not be able to be percussed. Palpating painful areas is not percussion, so is not correct. Using the bony
part of the palm at the base of the fingers or the ulnar surface is a technique used to detect tactile
fremitus.
Question 3
The palpation technique used to assess respiratory expansion of the chest is placing the hands on the
eight or tenth ribs posteriorly with the thumbs close to the vertebrae, sliding the hand medially and
grasping a small fold of skin between the thumbs. Then:
ask the patient to cough and note chest expansion.
,Correct: ask the patient to take a deep breathe and note any delay in expansion during
inhalation. have the patient hold his breath for 15 seconds then note chest expansion. have the
patient exhale forcefully noting expansion on expiration.
Explanation:
To assess the respiratory expansion of the chest, the examiner places his hands on the eight or tenth
ribs posteriorly with the thumbs close to the vertebrae, slides the hand medially and grasps a small fold
of skin between the thumbs then asks the patient to take a deep breath. The thumbs should move
evenly away from the vertebrae during inspiration and there should be no delay in expansion.
Question 4
When trying to differentiate between hemoptysis or blood streaked material, which one of the
following observations is correct?
Hemoptysis is seen frequently in infants, children, and adolescents with allergic rhinitis.
Blood originating in the stomach is usually brighter than blood originating from the respiratory tract.
Hemoptysis is common in children with cystic fibrosis.
Correct: Blood streaked material often originates from the gastrointestinal tract.
Explanation:
Hemoptysis is rare in infants, children, and adolescents, although common in those with cystic fibrosis.
Blood originating in the stomach is usually darker than blood from the respiratory tract and may be
mixed with food particles. Blood or blood-streaked material may originate in the mouth, pharynx, or
less commonly from the gastrointestinal tract.
Question 5
When percussing the chest in a patient who has left sided heart failure, the sound emanated would be:
Resonant. Correct dull tympany. Diffusely hyper resonant.
Explanation: A patient with left sided heart failure experiences increased pressure in the pulmonary
veins causing congestion and interstitial edema. Percussion sounds emitted would most likely be
resonant. Consolidation in the lungs produces a dull sound on percussion. Tympany (low-high pitched
musical sound) is usually audible when percussing a distended abdomen or when a pneumothorax is
present. Chronic obstructive lung disease produces diffusely hyperresonant sound on percussion.
, Question 6
The line that extends through the inferior angle of the scapula when the arms are at the sides of
the body is the: mid vertebral line. Correct : Scapular line.
midclavicular line mid-
spinal line
Explanation: The line that extends through the inferior angle of the scapula when the arms are at the
sides of the body is the scapular line.
Question 7
A condition associated with a chronic cough that produces copious amounts of purulent sputum is
most likely: tracheobronchitis. chronic bronchitis.
Bronchiectasis. laryngitis.
Explanation: An acute viral illness that presents with a burning retrosternal discomfort and a dry cough
is tracheobronchitis. An acute, mild illness often associated with viral nasopharyngitis and hoarseness is
laryngitis. The initial cough is dry and nonproductive but may become productive over time. A chronic
bronchitis cough is characteristically productive with mucoid to purulent sputum and may be blood
tinged. Bronchiectasis produces a chronic cough with sputum that is copious and foul-smelling. It may
be blood tinged.
Question 8
A patient who walked into the examination room, may be observed to be sitting and leaning forward in
his chair. Lips were pursed during exhalation and arms are supported on the table. This position could
be consistent with patients who have: pneumonia.
chronic obstructive pulmonary disease (COPD)
asthma croup.
Explanation: People who have chronic obstructive pulmonary disease experience shortness of breath
and dyspnea. Breathing with pursed lips and use of abdominal muscles help reduce shortness of breath
and dyspnea. Leaning forward while seated and having arms supported on the table facilitate breathing.
This position is not characteristic of the other diseases.
Question 9
Breath sounds heard over the periphery of the lung fields
are: bronchial. abnormal.
