B) remove the telephone to reduce myocardial oxygen demand.
C) add a box of surgical masks to the nursing supplies near the door.
D) remove the water pitcher to comply with anticipated fluid restrictions.

Question 5

The hyper-secretion of mucus resulting for chronic bronchitis is the result of

A) recurrent infection.
B) destruction of alveolar septa.
C) reduced inflammation.
D) barrel chest.

Question 6

Croup is characterized by

A) a productive cough.
B) a barking cough.
C) an inability to cough.
D) drooling, sore throat, and difficulty swallowing.

Question 7

Emphysema results from destruction of alveolar walls and capillaries, which is due to

A) release of proteolytic enzymes from immune cells.
B) air trapping with resultant excessive alveolar pressure.
C) excessive a1-antitrypsin.
D) autoantibodies against pulmonary basement membrane.

Question 8

When a client diagnosed with COPD type A asks, "Why is my chest so big and round?", the nurse responds that

A) "Loss of elastic tissue in your lungs allows your airways to close and trap air, which makes your chest round."
B) "Swelling and mucus in your airways causes air to be trapped in your lungs, which makes your chest round."
C) "Coughing caused by your condition has changed the structure of your airways, which makes your chest round."
D) "Scar tissue in your lungs makes them stiff and more full of air than usual, which makes your chest round."

Question 9

To best prevent emphysema, a patient is instructed to stop smoking since cigarette smoke

A) impairs alpha1-antitrypsin, allowing elastase to predominate.
B) paralyzes the cilia, causing impaired mucociliary clearance.
C) predisposes to respiratory infections.
D) introduces carcinogens into the lungs.

Question 10

When exposed to inhaled allergens, a patient with asthma produces large quantities of

A) IgG.
B) IgE.
C) IgA.
D) IgM.

Question 11

After evaluation, a child's asthma is characterized as "extrinsic." This means that the asthma is

A) of unknown pathogenesis.
B) associated with specific allergic triggers.
C) associated with respiratory infections.
D) induced by psychological factors (stress).

Question 12

Cystic fibrosis is associated with

A) asthma.
B) chronic bronchitis.
C) bronchiectasis.
D) emphysema.

Question 13

Copious amounts of foul-smelling sputum are generally associated with

A) emphysema.
B) epiglottitis.
C) pulmonary edema.
D) bronchiectasis.

Question 14

Lack of alpha₁-antitrypsin in emphysema causes

A) chronic mucus secretion and airway fibrosis.
B) destruction of alveolar tissue.
C) pulmonary edema and increased alveolar compliance.
D) bronchoconstriction and airway edema.

Question 15

Which pulmonary function test result is consistent with a diagnosis of asthma?

A) Reduced forced expiratory volume in 1 second (FEV1)
B) Decreased functional residual capacity
C) Increased FEV1
D) Reduced total lung volume

Question 16

Chronic bronchitis often leads to cor pulmonale because of

A) ventricular hypoxia.
B) increased pulmonary vascular resistance.
C) left ventricular strain.
D) hypervolemia.

Question 17

Allergic (extrinsic)asthma is associated with

A) hyporesponsiveness of airways.
B) unknown precipitating factors.
C) IgE-mediated airway inflammation.
D) irreversible airway obstruction.

Question 18

In individuals who have asthma, exposure to an allergen to which they are sensitized leads to which pathophysiological event?

A) Loss of alveolar elastin and premature closure of airways
B) Pulmonary edema and decreased alveolar compliance
C) Mast cell degranulation that causes decreased surfactant
D) Inflammation, mucosal edema, and bronchoconstriction

Question 19

All obstructive pulmonary disorders are characterized by

A) resistance to airflow.
B) hyperresponsiveness.
C) decreased residual volumes.
D) decreased lung compliance.

Question 20

Obstructive disorders are associated with

A) low residual volumes.
B) low expiratory flow rates.
C) increased expiratory reserve volume.
D) decreased total lung capacity.

Question 21

Characteristics of asthma include

A) chronic inflammatory disorder.
B) airway hyperresponsiveness.
C) alveolar collapse.
D) genetic susceptibility.
E) airway remodeling.

Question 22

The increased anterior-posterior chest diameter associated with obstructive lung disease is caused by

A) increased pulmonary blood flow.
B) increased expiratory flow rates.
C) increased residual lung volumes.
D) decreased chest wall compliance.

Question 23

When assessing an individual during an acute asthma episode, you should expect to find

A) use of accessory breathing muscles.
B) expiratory wheezing.
C) foul-smelling sputum.
D) coughing.
E) feeling of chest tightness.

Question 24

An acute asthma attack is associated with

A) bronchoconstriction.

Question 26

The assessment findings of a 5 year old with a history of asthma include extreme shortness of breath, nasal flaring, coughing, pulsus paradoxus, and use of accessory respiratory muscles.There is no wheezing and the chest is silent in many areas.How should you interpret your assessment?

A) The child probably has consolidated pneumonia; oxygen should be started immediately.
B) Since there is not wheezing, asthma is the problem, but oxygen should be started immediately anyway.
C) The signs and symptoms are consistent with asthma; start oxygen and then check to see that your stethoscope is working properly.
D) The child may be having such a severe asthma episode that the airways are closed, so start oxygen and get the doctor immediately.
