MULTIPLE CHOICE

 

1. ANS:  C

 

	Feedback
A	The intercostal muscles relax during expiration.
B	The ribs move inward during expiration.
C	When the diaphragm contracts in response to stimulus from the phrenic nerves, it moves downward, which increases the size of the chest cavity, resulting in inspiration/inhalation. Chapter Objective: Explain the mechanics of inhalation and exhalation.
D	Pressure within the lungs raises above atmospheric pressure during expiration.

2. ANS:  A

 

	Feedback
A	When carbon dioxide increases above normal amounts, it causes the blood to become more acidic. The chemoreceptors respond by sending the message to the medulla, which, in turn, causes the respiratory rate to increase to “blow off” or remove excess carbon dioxide, returning the blood pH to normal levels. Chapter Objective: Describe chemical and nervous regulation of respirations.
B	The breathing rate will increase, not slow.
C	The breathing rate will increase.
D	The breathing rate will increase, not stop.

3. ANS:  D

 

	Feedback
A	This is not the biggest concern.
B	Clubbing is often seen with long-term lung disease.
C	This is a normal finding.
D	When the patient has dark skin, the color may appear more ashen than cyanotic and the nurse will depend more on the color of the mucous membranes. The nurse should check the palms of the hands and soles of the feet for color changes as well. Safety: This is a late sign of hypoxia. The nurse should take action immediately and notify the health care provider stat. Chapter Objective: List inspection points in the assessment of a patient with impaired oxygenation.

4. ANS:  B

 

	Feedback
A	Cyanosis refers to skin discoloration.
B	When the patient is having difficulty moving air in and out of the lungs, it is referred to as dyspnea. Charting should be as specific as possible and use correct terminology. Chapter Objective: Define key terms associated with respiratory rate.
C	This is not specific.
D	Hypoxemia refers to decreased oxygenation and would require measurement of oxygen saturation to determine.
