NU 545 - UNIT 5 PRACTICE QUESTIONS AND ANSWERS
WITH COMPLETE SOLUTIONS VERIFIED
Which statement is true regarding the pulmonary system?
The larynx connects the upper and lower airways
Which statement is true regarding the lower airways?
The right and left main bronchi enter the lungs at the hila.
What process describes the exchange of carbon dioxide (CO2) for oxygen?
Respiration
Which receptor monitors the pH, partial pressure of CO2 (PaCO2), and the partial pressure of oxygen
(PaO2) in arterial blood?
Central chemoreceptors
Which physiologic alteration is present in an individual with emphysema?
Increased compliance
Which steps are involved in the process of gas exchange? (Select all that apply.)
Ventilation, Diffusion, Perfusion
Which structures are considered part of the upper airway? (Select all that apply.)
Nasopharynx, Oropharynx
, Which structures are considered part of the acinus? (Select all that apply.)
Respiratory bronchioles, Alveolar ducts, Alveoli
Which structures are major accessory muscles of respiration? (Select all that apply.)
Diaphragm, External Intercostals
Which alterations involved with aging are considered normal? (Select all that apply.)
Increased flow resistance, Alterations in gas exchange, Loss of recoil
The binding of oxygen to hemoglobin occurs in the lungs; the reverse process in which oxygen is
released from hemoglobin occurs in the?
Tissues
The mechanical movement of gas or air into and out of the lungs is known as ventilation. Breathing is
usually involuntary because changes in the rate and volume are adjusted automatically by the nervous
system to maintain normal gas exchange. The respiratory system in the brain that becomes active
when increased ventilatory effort is required is the?
Dorsal respiratory group
Which illness is a type of liquefactive necrosis?
Abscess
Which statement is true regarding bronchiolitis?
Respiratory distress develops within 24-72 hours
What is the appropriate term for inadequate alveolar ventilation in relation to metabolic demands?
Hypoventilation
