NUFT 204 - Respiratory Assessment (Latest 2023 - 2024) Actual Questions and Answers 100% Correct
- What body systems work together to supply oxygen to the body?
Answer: Cardio- vascular and respiratory
- What is the major function of the lungs?
Answer: Continuous gas exchange between inspired air and blood in the pulmonary
circulation
- What are the 3 steps of respiration?
Answer:
- Ventilation
- Perfusion
- Diffusion
- What is ventilation?
Answer: When oxygen comes into the lungs
- What is perfusion?
Answer: The blood flow that goes to the lungs and the tissues
- What is diffusion?
Answer: The exchange of gases that occurs in the alveoli
- Where does the respiratory tract begin and end?
Answer:
- Begins at the mouth/nose
- Ends at the alveoli of the lungs
- What is the function of the upper airway?
Answer: .
- Filters airborne particles
- Humidifies and warms inspired gases
- What is the function of the lower airway?
Answer: Serves as location for gas exchange
- / 3
- Which respiratory structures are part of the upper airway?
Answer:
- nose/nasal passages
- Pharynx
- Larynx
- Which respiratory structures are part of the lower airway?
Answer:
- Trachea
- Bronchi
- Bronchioles
- Alveoli
- Where is respiration controlled?
Answer: In the brainstem
- How many lobes does the right lung have? How many does the left lung have?
Answer:
- Right has 3
- Left has 2
- What type of process is expiration?
Answer: Passive
- What muscles mediate respiration?
Answer:
- Diaphragm
2. SCM
- Scalenes
- Intercostal
- Obliques
- What is the primary muscle of inspiration?
Answer: diaphragm
- / 3
- What occurs to the diaphragm and thorax during inspiration?
Answer:
- Diaphragm contracts
- Thorax expands (increases in size)
- What occurs to the diaphragm and thorax during expiration?
Answer:
- Diaphragm relaxes
- Thorax deflates (decreases in size)
*note: decreased size in thorax space assists with pushing air out*
- Describe the technique for doing a respiratory exam.
Answer:
- Ensure a quiet environment
- Properly position patient
-when listening posteriorly should be seated -when listening anteriorly can be supine or seated
- Ensure patient comfort
-make sure hands and stethoscope are warm -use drape sheet to cover women's chest
- Inspect then palpate then percuss then auscultate lungs
-auscultation should be done on bare skin -palpation and percussion aren't done often by nurses -for auscultation should start posteriorly then laterally then anteriorly -for auscultation should compare B/L (i.e. use ladder pattern)
- What is the normal adult respiration rate?
Answer: 12 to 20
- What should be assessed during initial respiratory survey?
Answer:
- Observe patient's breathing pattern (includes RATE, DEPTH, and EFFORT)
- Assess A-P diameter
- Assess patient's color
