Flashcards in Midterm 1 Deck (31):
1

What breathing pattern is associated with diabetic ketoacidosis?

Kussmal's Breathing

2

Your 50-year-old patient has a heart rate by palpation of 120 bpm. How should this be interpreted?

Tachycardia

3

While assessing an unconscious patient, you observe that her breathing becomes progressively faster and deeper and then progressively becomes slower and more shallow. After that, there is a period of apnea before the cycle begins again. This breathing pattern would be identified as:

Cheyne stokes

4

Deep breaths followed by shallow breathing and apnea?

Cheyne stokes

5

You're patient with bronchiectasis has a productive cough. As the respiratory therapist, what should you be evaluating about the patient's sputum?

Color, Odor, Amount, Consistency

6

breathlessness as perceived by the patient

dyspnea

7

An inability to breathing while lying down

orthopnea

8

What breathing pattern is associated with fatigue of the diaphragm?

Abdominal paradox

9

What clinical disorder will cause decreased resonance to percussion?

Pneumonia

10

Which of the following devices are most commonly used to deliver aerosols by inhalation route?

dry powder inhaler, metered dose inhaler, small-volume nebulizer

11

For chest compressions to be effective, in what position must the patient be placed?

Horizontal supine, on a firm surface

12

What is the proper rate of external chest compressions for adults

100/min

13


During two-person CPR applied to an adult, what is the proper ratio of compressions to ventilation?

30 compressions for every two breaths

14

What is the primary goal of humidity therapy

Maintain normal physiologic conditions

15

The greater the temperature of the gas, the:

more water vapor it can hold

16

Which of the following types of humidifiers are used in clinical practice?

heat-moisture exchanger,
Passover humidifier,
bubble humidifier

17


For which of the following patients might you recommend bland aerosol therapy administration?

patient with upper airway edema,
patient with a bypassed upper airway,
patient who must provide a sputum specimen

18

What is the most common device used to generate bland aerosols?

Large-volume jet nebulizer

19

A physician orders bland water aerosol administration to a patient with an intact upper airway. Which of the following airway appliances could you use to meet this goal?

face tent and aerosol mask

20

A patient receiving nasal oxygen at 3 L/min complains of nasal dryness and irritation. Which of the following actions would be appropriate?

Adding a humidifier to the delivery system

21

Which of the following best defines an aerosol?

Suspension of liquid or solid particles in a gas

22


What measure is used to identify the particle diameter, which corresponds to the most typical settling behavior of an aerosol?

Mean mass aerodynamic diameter (MMAD)

23

Most nebulizers used in respiratory care produce which type of aerosol suspension?

Heterodisperse

24

What is the retention of aerosol particles resulting from contact with the respiratory tract mucosa called?

Deposition

25

What is the primary mechanism for deposition of large, high-mass particles (greater than 5 µm) in the respiratory tract?

Inertial impaction

26

Where do most aerosol particles in the 5- to 10- µm range deposit?

Upper airways

27

What is the primary mechanism for central airway deposition of particles in the 1- 5- µm range?

Sedimentation

28

Which of the following techniques will increase aerosol deposition by sedimentation in the lungs?

10-second breath hold

29

What term describes the primary mechanism for deposition of small particles?

Brownian diffusion

30

A physician wants to deliver a therapeutic aerosol to the central and lower airways. To help ensure maximum deposition in this area, you would select an aerosol generator with an MMAD in what range?

2 to 5 µm

31

Which of the following devices depends on the patient's INSPIRATORY EFFORT to dispense the dose?

DPI
