BSN 346 EXAM 4 QUESTIONS AND
CORRECT ANSWERS!!
Respiratory System:
Question 1 of 3
Which component of the respiratory system contracts and flattens to cause inspiration?
Diaphragm
Alveoli
Trachea
Lungs
Diaphragm
The diaphragm is a muscle of the respiratory system that contracts and flattens to increase lung
volume and cause inspiration.
Question 3 of 3
Which statements correctly describe the structures in the lower respiratory tract?
Select all that apply.
The parietal pleura encases each lung.
The left main bronchus branches off the trachea.
The upper, middle, and lower lobes comprise the right lung.
The trachea conducts air between the pharynx and the lungs.
The alveoli are found at the terminal end of the main bronchi.
The upper, middle, and lower lobes comprise the right lung.
The right lung has three lobes namely: upper, middle, and lower lobes.
The alveoli are found at the terminal end of the main bronchi.
The main bronchi, which are divided into lobar bronchi, segmental bronchi, and bronchioles,
terminate in alveoli.

Question 1 of 5
A 12-month-old child with a respiratory infection begins crying while the nurse is
auscultating for posterior lung sounds. Which intervention is most appropriate?
, Stop the assessment to avoid stressing the child
Compress the stethoscope against the chest wall
Allow parent to hold child and continue with assessment
Encourage child to blow bubbles and continue assessment
Allow parent to hold child and continue with assessment
Allowing the parent to hold a child who begins crying while the nurse is auscultating the lungs
may console the child from crying and it is the most appropriate intervention for this situation.
Question 2 of 5
A 9-year-old child presents at the Outpatient Unit with reports of runny nose, cough, and
fever for two days. Demonstrate the appropriate method of conducting respiratory
assessment in this child by organizing the sequential steps listed.
Inspect chest configuration
Count respiratory rate
Auscultate starting in the posterior then anterior thorax
Palpate chest for pectus carinatum
Perform chest percussion
Question 3 of 5
While inspecting the thorax of a 3-year-old child, the nurse notes an increased respiratory
rate and retractions while the child is supine on the examining table. Which action can the
nurse perform next to obtain an accurate respiratory assessment?
Reposition the child upright.
Begin auscultating the lungs.
Ask the child to blow a tissue.
Allow the child to hold the stethoscope.
Reposition the child upright.
Positioning the child upright (a position of comfort) can assist with auscultation of the lungs,
which is the next step of the assessment for a child with signs of respiratory distress, and can
facilitate precise respiratory assessment findings.
