Flashcards in Midterm 1 Deck (31):
What breathing pattern is associated with diabetic ketoacidosis?
Your 50-year-old patient has a heart rate by palpation of 120 bpm. How should this be interpreted?
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:
Deep breaths followed by shallow breathing and apnea?
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
breathlessness as perceived by the patient
An inability to breathing while lying down
What breathing pattern is associated with fatigue of the diaphragm?
What clinical disorder will cause decreased resonance to percussion?
Which of the following devices are most commonly used to deliver aerosols by inhalation route?
dry powder inhaler, metered dose inhaler, small-volume nebulizer
For chest compressions to be effective, in what position must the patient be placed?
Horizontal supine, on a firm surface
What is the proper rate of external chest compressions for adults
During two-person CPR applied to an adult, what is the proper ratio of compressions to ventilation?
30 compressions for every two breaths
What is the primary goal of humidity therapy
Maintain normal physiologic conditions
The greater the temperature of the gas, the:
more water vapor it can hold
Which of the following types of humidifiers are used in clinical practice?
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
What is the most common device used to generate bland aerosols?
Large-volume jet nebulizer
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
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
Which of the following best defines an aerosol?
Suspension of liquid or solid particles in a gas
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)
Most nebulizers used in respiratory care produce which type of aerosol suspension?
What is the retention of aerosol particles resulting from contact with the respiratory tract mucosa called?
What is the primary mechanism for deposition of large, high-mass particles (greater than 5 µm) in the respiratory tract?
Where do most aerosol particles in the 5- to 10- µm range deposit?
What is the primary mechanism for central airway deposition of particles in the 1- 5- µm range?
Which of the following techniques will increase aerosol deposition by sedimentation in the lungs?
10-second breath hold
What term describes the primary mechanism for deposition of small particles?
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
