NRP511 Advanced Pathophysiology

Week 5 Quiz

Question 1A patient is having a spirometry measurement done and asks the healthcare professional to explain this test. What response by the professional is best?

To evaluate the cause of hypoxia

To measure the volume and flow rate during forced expiration

To measure the gas diffusion rate at the alveolocapillary membrane

To determine pH and oxygen and carbon dioxide concentrations

Question 2A 7 year-old-child presents to the clinic where parents report signs and symptoms consistent with asthma. What does the healthcare professional do in order to confirm this diagnosis?

Assess for a parental history of asthma

Draw serum levels of immunoglobulin E (IgE) and eosinophil levels

Measure expiratory flow rate with spirometry testing

Give a trial of asthma medication and check for improvement

Question 3Why is nasal congestion a serious threat to young infants?

Infants are obligatory nose breathers.

Their nares are small in diameter.

Infants become dehydrated when mouth breathing.

Their epiglottis is proportionally greater than the epiglottis of an adult’s.

Question 4The core defects of asthma include: (choose the best response)

inflammation/alveolar destruction/bronchoconstriction

mucous production/alveolar destruction/bronchoconstriction

inflammation/mucous production/bronchoconstriction

obstruction/mucous production/bronchoconstriction

Question 5What does the student learn about ventilation?

Hypoventilation causes hypocapnia.

Hypoventilation causes alkalosis.

Hyperventilation causes hypocapnia.

Question 7Bronchiolitis tends to occur during the first years of life and is most often caused by what type of infection?

Respiratory syncytial virus (RSV)

Influenza virus

Adenoviruses

Rhinovirus

Question 8Which statement best describes cystic fibrosis?

Obstructive airway disease characterized by reversible airflow obstruction, bronchial hyperreactivity, and inflammation

Respiratory disease characterized by severe hypoxemia, decreased pulmonary compliance, and diffuse densities on chest x-ray imaging

Pulmonary disorder involving an abnormal expression of a protein-producing viscous mucus that obstructs the airways, pancreas, sweat ducts, and vas deferens

Pulmonary disorder characterized by atelectasis and increased pulmonary resistance as a result of a surfactant deficiency
