MULTIPLE CHOICE

 

1. The primary indication for lung expansion therapy is:

a.	asthma.	c.	chronic bronchitis.
b.	atelectasis.	d.	respiratory distress.

 

 

ANS:  B

Lung expansion therapy is used to either prevent or treat atelectasis.

 

PTS:   1                    REF:   Page 213

 

2. Factors that increase the risk of atelectasis include:

a.	productive cough.
b.	lower extremity paralysis.
c.	decreased intra-abdominal pressure.
d.	chronic obstructive pulmonary disease.

 

 

ANS:  D

Factors that contribute to the development of atelectasis include retained secretions, altered breathing patterns, pain associated with surgery and trauma, chronic obstructive pulmonary disease, prolonged immobilization in a supine position, and increased intra-abdominal pressure.

 

PTS:   1                    REF:   Pages 213-214

 

3. Untreated atelectasis can result in which of the following?
4. Decreased shunting
5. Increased shunting
6. Hypercapnia
7. Hypocapnia

a.	1 and 3	c.	1 and 4
b.	2 and 3	d.	2 and 4

 

 

ANS:  B

If atelectasis goes untreated, it can lead to pulmonary shunting, hypoxemia, hypercapnia, and ultimately respiratory failure.

4. Contraindications for incentive spirometry include:

a.	post-thoracic surgery.
b.	vital capacity less than 10 mL/kg.
c.	restrictive pulmonary disease.
d.	inspiratory capacity greater than predicted value.

 

 

ANS:  B

A vital capacity of less than 10 mL/kg demonstrates that the patient is unable to breathe deeply, effectively rendering the patient unable to perform the maneuver that is necessary to achieve positive results. Incentive spirometry is indicated for post-thoracic surgery and restrictive pulmonary disease. If a patient has an inspiratory capacity greater than predicted, that patient would be able to perform incentive spirometry.

 

PTS:   1                    REF:   Page 214

 

5. Indications for incentive spirometry include:

a.	post-abdominal surgery.
b.	respiratory muscle weakness.
c.	optimization of bronchodilator therapy.
d.	inability to effectively deep breathe.

 

 

ANS:  A

Abdominal surgery predisposes a patient to the development of pulmonary atelectasis. Patients with respiratory muscle weakness or the inability to effectively deep breathe will not be able to perform incentive spirometry and therefore will not benefit from its use. Incentive spirometry is not used to optimize bronchodilator therapy.
