Q1 QUESTION 1 OF 222
What are two pulmonary causes leading to respiratory acidosis?
a. Asthma and shortness of breath
b. Hyperventilation and fever
c. Cystic fibrosis and hypoventilation
d. Anemia and pain
CORRECT ANSWER
c. Cystic fibrosis and hypoventilation
RATIONALE
Cystic fibrosis impairs gas exchange by obstructing airways, and hypoventilation leads to insufficient exhalation of carbon
dioxide, both increasing arterial CO2 levels and causing respiratory acidosis. This question assesses understanding of
conditions that impede alveolar ventilation and CO2 elimination.
Q2 QUESTION 2 OF 222
Which issue would a child with Neurobehavioral Disorder
Associated with Prenatal Alcohol Experts (HD-PAE) exhibit?
a. Nearsightedness
b. Trouble planning
c. Frequent nausea
d. Helpfulness
CORRECT ANSWER
b. Trouble planning
RATIONALE
Executive dysfunction, particularly impaired planning and organization, is a hallmark cognitive deficit in children with HD-PAE
due to disruptions in frontal lobe development from prenatal alcohol exposure. This core deficit underlies difficulties with
goal-directed behavior and impulse control.

, Q3 QUESTION 3 OF 222
Which assessment findings are associated with chronic
obstructive pulmonary disease (COPD)?
a. Bradycardia and decreased urine output
b. Weak, thready pulse and warm, dry skin
c. Dyspnea and audible wheezing
d. Unlabored respirations and leg edema
CORRECT ANSWER
c. Dyspnea and audible wheezing
RATIONALE
Dyspnea and audible wheezing are hallmark signs of airflow obstruction and bronchoconstriction characteristic of COPD. This
reflects the underlying pathophysiology of impaired gas exchange and increased airway resistance.
Q4 QUESTION 4 OF 222
What is an upper respiratory tract infection?
CORRECT ANSWER
Common cold, laryngitis, croup, pharyngitis,
rhinitis, sinusitis, and tonsillitis
RATIONALE
Upper respiratory tract infections (URTIs) are infectious diseases affecting the nasal cavity, pharynx, larynx, and trachea,
commonly manifesting as conditions like the common cold, sinusitis, pharyngitis, laryngitis, croup, rhinitis, and tonsillitis. This
category encompasses a range of viral and bacterial illnesses localized to the upper airway structures.
Q5 QUESTION 5 OF 222
What is a lower respiratory tract infection?
CORRECT ANSWER
Pneumonia, bronchitis, tuberculosis
Page 3
, RATIONALE
Lower respiratory tract infections affect the bronchi and lungs, with pneumonia and bronchitis being common examples, while
tuberculosis is a specific infectious disease of the lungs. This question assesses understanding of anatomical localization for
respiratory pathologies.
Q6 QUESTION 6 OF 222
What conditions lead to COPD?
CORRECT ANSWER
Smoking, asthma, dust, chemicals, genetics
RATIONALE
Chronic obstructive pulmonary disease (COPD) arises from prolonged exposure to irritants like cigarette smoke and air
pollutants, or from genetic factors such as alpha-1 antitrypsin deficiency, which impair lung function and cause inflammation.
Asthma can also contribute to COPD development due to persistent airway inflammation and remodeling.
Q7 QUESTION 7 OF 222
What is pneumonia?
CORRECT ANSWER
An inflammation in the lung caused by
infection from bacteria, viruses, fungi, or parasites, or resulting
from aspiration of chemicals. Hear crackles and rhonchi
RATIONALE
Pneumonia is an inflammatory condition of the lung parenchyma often caused by infectious agents, leading to alveolar
consolidation and impaired gas exchange, evidenced by adventitious lung sounds like crackles. The key concept tested is the
definition and characteristic physical findings of pneumonia.
Q8 QUESTION 8 OF 222
What is asthma?
CORRECT ANSWER
Treatment-resistant bronchospasm, same
category as COPD
