Question 1

The nurse notes the client experienced a temporary cessation of breathing while sleeping.The nurse would document this as "The client experienced periods of _____."

Accepted Answer

Apnea is a temporary cessation of breathing,most frequently occurring during sleep.

Question 2

What is the purpose of the alveolar macrophages?

Accepted Answer

The alveolar ducts are smooth,muscular tubes containing abundant alveolar macrophages that remove foreign particles such as bacteria.

Question 3

What is the movement of gases across the alveolar capillary membrane from areas of high concentration to areas of lower concentration called?

Accepted Answer

Diffusion is the movement of a solute from an area of higher solute concentration to an area of lower solute concentration across a membrane.

Question 4

When administering oxygen to clients with conditions such as emphysema,it is important for the nurse to remember that for these clients the:

Accepted Answer

The drive to breathe is based on the concentration of carbon dioxide levels and may be dependent on low levels of oxygen in the blood.

Question 5

The nurse is aware that the movement of gases into and out of the lung is called:

Accepted Answer

The movement of gases into and out of the lung is called perfusion.

Question 6

The flow of blood through the vessels of a specific organ or body part is called:

Accepted Answer

The flow of blood through the vessels of a specific organ or body part is called perfusion.

Question 7

What is the mechanism of gas exchange at the alveolar capillary membrane?

Accepted Answer

Diffusion is the movement of a solute from an area of higher solute concentration to an area of lower solute concentration across a membrane.

Question 8

The respiratory tissues perform which of these functions?

Accepted Answer

The appearance of the alveoli and the alveolar ducts resemble a cluster of grapes.Gas exchange occurs in these respiratory tissues.

Question 9

What is the primary site for gas exchange?

Accepted Answer

The primary site for gas exchange occurs in the alveoli.

Question 10

When blood within the pulmonary capillary network is oxygenated,it travels to the heart via which structure?

Accepted Answer

Once the blood within the pulmonary capillary network is oxygenated,it travels to the heart via the pulmonary vein.

Question 11

Which of these statements about the pressure within the pleural space is TRUE?

Accepted Answer

The pressure of the pleural space is less than the pressure of outside air.

Question 12

Collectively,what do the alveoli and the alveolar ducts resemble?

Accepted Answer

The appearance of the alveoli and the alveolar ducts resemble a cluster of grapes.

Question 13

What is the function of type I alveolar cells?

Accepted Answer

The primary site for gas exchange occurs in the alveoli.Type I alveolar cells function to produce surfactant.

Question 14

What is the result of the difference between the pressure within the pleural space and the pressure of the outside air?

Accepted Answer

The pressure of the pleural space has less than the pressure of outside air,which prevents the lungs from collapsing on exhalation.

Question 15

How do the mucus of the goblet cells and the cilia of the conducting airways protect the respiratory system from invasion from foreign particles?

Accepted Answer

The goblet cells and the cilia of the conducting airways protect the respiratory system from invasion from foreign particles.The constant upward motion of the cilia propels the mucociliary blanket toward the pharynx where foreign matter may be expectorated.

Question 16

The conducting airways are lined with which of the following?

Accepted Answer

The conducting airways are lined with cilia to filter and trap particles from entering the lungs.

Question 17

Exchange of gases at the cellular level between tissue cells and blood is an example of:

Accepted Answer

Exchange of gases at the cellular level between tissue cells and blood is called internal respiration.

Question 18

When the nurse assesses the function that provides the body with a means of gas exchange,it includes an evaluation of:

Accepted Answer

The function that provides the body with a means of gas exchange is respiration.

Question 19

Which of these routes delivers blood to the alveoli for gas exchange?

Accepted Answer

Blood is returned in the pulmonary system to the alveoli for gas exchange.

Question 20

What is the name of the transparent membrane covering the lungs?

Accepted Answer

The pleura is the transparent membrane covering the lungs.
