Question 1

Which of the following is not a cause of pneumonia?&#10;A) Aspiration of food&#10;B) Inhalation of toxic chemicals&#10;C) Bacterial infection&#10;D) Congestive heart failure

Accepted Answer

Pneumonia is an inflammation of the lungs that can be caused by aspiration of food, fluids, or vomitus; inhalation of toxic or caustic chemicals, smoke, dust, or gasses; or a bacterial, viral, or mycoplasmal infection.

Question 2

Sudden dilatation of which chamber of the heart could be the result of a pulmonary embolism (PE)?&#10;A) Right atrium&#10;B) Right ventricle&#10;C) Left atrium&#10;D) Left ventricle

Accepted Answer

Cor pulmonale is a serious cardiac condition and an emergency situation arising from a sudden dilatation of the right ventricle as a result of PE.

Question 3

Which lung disease is characterized by abnormal and permanent dilation of the large passages leading into the lungs and by destruction of bronchial walls?&#10;A) Emphysema&#10;B) Bronchiectasis&#10;C) Chronic bronchitis&#10;D) Acute bronchitis

Accepted Answer

Bronchiectasis is a form of obstructive lung disease and is actually a type of bronchitis. It is characterized by abnormal and permanent dilation of the large passages leading into the lungs and by destruction of the bronchial walls.

Question 4

A client with cystic fibrosis (CF) is unable to pass which of the following ions in and out of cells?&#10;A) Sodium&#10;B) Chloride&#10;C) Potassium&#10;D) Iron

Accepted Answer

In healthy people a protein called CF transmembrane conductance regulator provides a channel by which chloride can pass in and out of cells. People with CF have a defective copy of this gene that normally enables cells to construct that channel.

Question 5

What is most often the first sign or symptom of lung cancer?&#10;A) Shortness of breath&#10;B) Hemoptysis&#10;C) Cough&#10;D) Shoulder pain

Accepted Answer

In many instances lung cancer may mimic other pulmonary conditions or may initially appear as chest, shoulder, or arm pain. Pulmonary symptoms such as cough, hemoptysis, and dyspnea are uncommon until late in the disease.

Question 6

Which of the following individuals has the least chance for the development of tuberculosis (TB)?&#10;A) Healthcare worker&#10;B) A 12-year-old white child&#10;C) An individual who is incarcerated&#10;D) Immigrant from Southeast Asia

Accepted Answer

The other individuals mentioned in the question all are at greater risk for development of TB.

Question 7

Textile workers are at greatest risk for development of which of the following lung disorders?&#10;A) Black lung disease&#10;B) Asbestosis&#10;C) Byssinosis&#10;D) Mesothelioma

Accepted Answer

Byssinosis (brown lung disease), caused by dust from hemp, flax, and cotton processing, results in chronic obstruction of the small airways, impairing lung function. Textile workers are at greatest risk for disability from byssinosis.

Question 8

What type of emphysema usually occurs in the upper lung regions?&#10;A) Centrilobular emphysema&#10;B) Panlobular emphysema&#10;C) Paraseptal emphysema&#10;D) Panacinar emphysema

Accepted Answer

Centrilobular emphysema, the most common type, destroys the bronchioles, usually in the upper lung regions. Inflammation develops in the bronchioles, but the alveolar sac remains intact.

Question 9

What is the most common cause of Cheyne-Stokes respiration (CSR)?&#10;A) Basilar artery infarct&#10;B) Congestive heart failure&#10;C) Damage to the medulla&#10;D) Paralysis of the chest wall muscles and thorax

Accepted Answer

The most common cause of CSR is severe congestive heart failure, but it can also occur with renal failure, meningitis, drug overdose, and increased intracranial pressure.

Question 10

A productive cough with nonpurulent sputum indicates which of the following?&#10;A) Infection&#10;B) Simple airway irritation&#10;C) Pneumonia&#10;D) Tumor

Accepted Answer

A productive cough with purulent sputum may indicate infection, whereas a productive cough with nonpurulent sputum is nonspecific and indicates airway irritation. Rust-colored sputum may be a sign of pneumonia, and hemoptysis indicates a pathologic condition such as infection, inflammation, abscess, tumor, or infarction.

Question 11

Stimulation of the central portion of the diaphragmatic pleura results in sharp pain referred to what body structure?&#10;A) Lumbar area&#10;B) Upper trapezius muscle and shoulder on the contralateral side of the stimulation&#10;C) Upper trapezius muscle and shoulder on the ipsilateral side of the stimulation&#10;D) Upper trapezius muscle and lumbar area

Accepted Answer

The answer of Stimulation of the central portion of the...

Question 12

What is the normal pH range of the human body?&#10;A) 7-7.25&#10;B) 7.25-7.35&#10;C) 7.35-7.45&#10;D) 7.40-7.50

Accepted Answer

The answer of What is the normal pH range of...

Question 13

Chronic bronchitis is characterized by&#10;A) Mucous hypersecretion and hypertrophy of mucus-producing cells in the bronchi&#10;B) Mucous hypersecretion and atrophy of mucus-producing cells in the bronchi&#10;C) Mucous hyposecretion and hypertrophy of mucus-producing cells in the bronchi&#10;D) Mucous hyposecretion and atrophy of mucus-producing cells in the bronchi

Accepted Answer

The answer of Chronic bronchitis is characterized by&#10;A) Mucous hypersecretion...

Question 14

Which of the following is the most common pulmonary manifestation of systemic sclerosis?&#10;A) Aspiration pneumonia&#10;B) Pneumothorax&#10;C) Neoplasm&#10;D) Pulmonary vascular disease

Accepted Answer

The answer of Which of the following is the most...

Question 15

What is the usual cause of respiratory alkalosis?&#10;A) Overdose of respiratory depressant drugs&#10;B) Obstruction of lung airways&#10;C) Weakness of respiratory muscles&#10;D) Hyperventilation
