Respiratory System Introduction
questions with correct answers 100%.

Which action would be done first if it is suspected that the patient has acute epiglottis? ANS - Ordering
radiographs of the neck.



Rationale: Radiographs of the neck should be ordered to confirm epiglottis.



Which type of breathing pattern is most likely to occur in a patient with renal failure? ANS - Kussmaul
respirations.



Rationale: Kussmaul respirations can occur with metabolic acidosis, diabetic keto acidosis, and renal
failure.



A patient's breathing pattern is regular, the depth is even, and the rate is faster than 20 beats per
minute. Which breathing pattern will be documented by the Licensed Practical Nurse (LPN)? ANS -
Tachypnea



Rationale: This breathing pattern is tachypnea, which can result from fever, pain, and anxiety. Normal
breathing has a regular pattern, an even depth, and a rate of 12 to 20 breaths per minute.



A patient reports smoking 2.5 packs of cigarettes per day for 24 years. Calculate the pack-years of this
patient's smoking. Record your answer using a whole number. ANS - 60 pack-years



Rationale: To calculate packs-years for a patient, multiply the number of packs smoked per day by the
number of years the patient smoked. For this patient, 2.5 packs per day times 24 years equals 60 pack-
years.



Where does the exchange of oxygen and carbon dioxide take place in the respiratory system? ANS -
Through the walls of the alveoli.

, Rationale: The exchange of oxygen and carbon dioxide takes place through the walls of the alveoli.



Which features/structures are part of the internal nose? Select all that apply. ANS - Mucus, vestibule,
turbinates, olfactory cells, branch of the internal and external carotids.



Rationale: The outermost portion of the internal nose is called the vestibule. The internal nose is
supplied with blood by branches of the internal and external carotids. A layer of mucus covers the
membrane. The side walls of the internal nose have folds of tissue called turbinates. Olfactory cells line
the roof of the nasal cavity. The external nose is made up of bone, cartilage, and mucous membrane.



Which sound is caused by secretions accumulating in the large airways, and usually clears with
coughing? ANS - Coarse crackles.



Rationale: A coarse crackle is a discontinuous, popping lung sound that usually results from secretions
accumulating in the larger airways; these crackles usually clear with coughing.



A patient has smoked two packs of cigarettes per day for the past 25 years. Calculate the cigarette pack-
year history for this patient. Record your answer using a whole number. _____ pack-years ANS - 50
pack-years



Pack-years are calculated by multiplying the number of years the patient smoked cigarettes by the
number of packs smoked each day. 25 years × 2 packs a day = 50 pack-years.



A patient complains of difficulty with breathing when in a lying position. Which term describes this
phenomenon? ANS - Orthopnea



Rationale: Orthopnea is shortness of breath that occurs when someone is lying flat. Apnea is the
temporary cessation of breathing, which often occurs while someone is asleep. Dyspnea is difficult or
labored breathing. Emphysema is a condition in which the air sacs of the lungs are damaged and
enlarged, leading to difficulty breathing.



Which radiologic study is most appropriate for measuring the speed and degree of lung expansion? ANS
- Fluoroscopy.
