Question 1

The region of the chest containing the heart,aorta,esophagus,trachea,bronchial tubes,and thymus is known as the ____.
A) manubrium
B) mediastinum
C) pleural cavity
D) pleural space

Accepted Answer

The mediastinum is the central region of the thoracic cavity and contains vital organs such as the heart, great vessels, trachea, bronchi, esophagus, and thymus. The other three options do not accurately describe this particular region of the chest.

Question 2

What structure,commonly known as the Adam's apple,protects the larynx?
A) epiglottis
B) mediastinum
C) thyroid cartilage
D) trachea

Accepted Answer

The thyroid cartilage, also known as the Adam's apple, is the structure that protects the larynx, which contains the vocal cords. The other options (epiglottis, mediastinum, trachea) are not directly involved in protecting the larynx.

Question 3

A ____ pumps air or oxygen through a liquid medicine to turn it into a vapor,which is then inhaled by the patient via a face mask or mouthpiece.
A) nasal cannula
B) nebulizer
C) positive pressure ventilator
D) respirator

Accepted Answer

A nebulizer is a device that turns liquid medication into a mist or vapor that can be inhaled by a patient. This is done by pumping air or oxygen through the liquid medication, which is then turned into a mist or vapor that can be inhaled by the patient via a face mask or mouthpiece. A nasal cannula is a different type of device used to deliver oxygen directly into a patient's nose. Positive pressure ventilators and respirators are also different types of devices used to help patients breathe, but they do not involve the use of nebulizers.

Question 4

Which term describes the exchange of gases within the cells of all the body organs and tissues?
A) alveolar exchange
B) external respiration
C) intercellular exchange
D) internal respiration

Accepted Answer

Internal respiration describes the exchange of gases (oxygen and carbon dioxide) within the cells of all the body's organs and tissues. This process involves the uptake of oxygen by the cells for cellular respiration and the release of carbon dioxide, which then enters the bloodstream for transport back to the lungs for elimination. Alveolar exchange and external respiration both involve the exchange of gases between the respiratory system and the environment, while intercellular exchange is a more general term and does not specifically refer to gas exchange.

Question 5

____ is the abnormal buildup of carbon dioxide in the blood.
A) Anoxia
B) Hypercapnia
C) Hypernea
D) Hypoxemia

Accepted Answer

Hypercapnia is the medical term for an abnormal buildup of carbon dioxide in the blood. Anoxia refers to a complete lack of oxygen, hypernea is an increase in the depth and rate of breathing and hypoxemia is a low level of oxygen in the blood.

Question 6

Functional endoscopic sinus surgery is performed to ____.
A) enlarge the opening between the nose and sinus
B) endoscopically examine the ethmoid sinuses
C) examine the frontal sinuses
D) repair the nasal septum

Accepted Answer

Functional endoscopic sinus surgery is performed to enlarge the opening between the nose and sinus in order to improve drainage of the sinuses and relieve symptoms of chronic sinusitis. It is not performed to examine specific sinuses or repair the nasal septum.

Question 7

Which upper respiratory bacterial infection is characterized by a paroxysmal cough?
A) croup
B) diphtheria
C) influenza
D) pertussis

Accepted Answer

Pertussis, also known as whooping cough, is a bacterial infection that is characterized by a paroxysmal cough, which is a severe, uncontrollable cough that may be followed by a high-pitched intake of breath (the "whoop" sound). The other options (croup, diphtheria, and influenza) may cause respiratory symptoms but do not typically result in a paroxysmal cough.

Question 8

Which of the following surrounds each lung?
A) parietal pleura
B) pleural cavity
C) pleural space
D) visceral pleura

Accepted Answer

The visceral pleura is the thin membrane that tightly covers the surface of each lung.

Question 9

The term ____ describes paralysis of the larynx.
A) dysphonia
B) laryngitis
C) laryngoplegia
D) laryngospasm

Accepted Answer

Laryngoplegia is the term used to describe paralysis of the larynx. A is incorrect because dysphonia refers to difficulty in speaking, not necessarily paralysis. B is incorrect because laryngitis is an inflammation of the larynx, not paralysis. D is incorrect because laryngospasm refers to a sudden involuntary contraction of the larynx, not paralysis.

Question 10

____ is the absence of oxygen from the body's gases,blood,or tissues.
A) Anoxia
B) Asphyxiation
C) Cyanosis
D) Suffocation

Accepted Answer

Anoxia specifically refers to the absence of oxygen from the body's gases, blood, or tissues. Asphyxiation and suffocation both involve a lack of oxygen, but can also refer to other mechanisms such as a blocked airway or inability to breathe. Cyanosis refers to a bluish coloration of the skin or mucus membranes due to a lack of oxygen in the blood.

Question 11

A pattern of alternating periods of hypopnea or apnea,followed by hyperpnea is known as ____.
A) Cheyne-Stokes respiration
B) dyspnea
C) hyperventilation
D) hypoxemia

Accepted Answer

The pattern of alternating periods of hypopnea or apnea, followed by hyperpnea is known as Cheyne-Stokes respiration. This is a type of abnormal breathing pattern often seen in patients with heart failure, neurological disorders, or sleep apnea. Dyspnea refers to difficult or labored breathing, hyperventilation refers to excessive breathing, and hypoxemia refers to low oxygen levels in the blood.

Question 12

Which diagnostic test measures the oxygen saturation level in the blood?
A) pulmonary function test
B) peak flow meter
C) pulse oximeter
D) spirometry

Accepted Answer

Pulse oximeter measures the oxygen saturation level in the blood by detecting the amount of oxygen attached to hemoglobin in red blood cells.

Question 13

Which condition is the absence of spontaneous respiration?
A) apnea
B) bradypnea
C) eupnea
D) tachypnea

Accepted Answer

Apnea is defined as the complete absence of spontaneous respiration. Bradypnea refers to slow breathing, eupnea is normal breathing, and tachypnea is rapid breathing.

Question 14

The loss of the ability of the larynx to produce normal speech sounds is known as
A) aphasia
B) aphonia
C) dysphonia
D) laryngitis

Accepted Answer

Aphonia refers to the loss of the ability to produce normal speech sounds, often due to damage or disease of the larynx. Aphasia refers to difficulty with language and communication, typically due to brain damage. Dysphonia refers to a hoarse or strained voice, often due to vocal cord disorders. Laryngitis refers to inflammation of the larynx, which can cause hoarseness or voice loss but is typically temporary.

Question 15

In ____ the airways have become inflamed and thickened,and there is an increase in the number and size of mucus-producing cells.
A) asthma
B) chronic bronchitis
C) chronic obstructive pulmonary disease
D) emphysema

Accepted Answer

The description is characteristic of chronic bronchitis, which is a type of chronic obstructive pulmonary disease (COPD). Asthma involves inflammation and narrowing of the airways, but there is not necessarily an increase in mucus-producing cells. Emphysema involves damage to the air sacs and loss of elasticity in the lungs.

Question 16

Which condition is the abnormal escape of fluid into the pleural cavity?
A) pleural effusion
B) pneumothorax
C) pyothorax
D) hemothorax

Accepted Answer

Pleural effusion is the abnormal accumulation of fluid in the pleural cavity, which can occur due to various reasons such as heart failure, pneumonia, cancer, or kidney disease. Pneumothorax is the presence of air in the pleural cavity, while pyothorax (also known as empyema) is the accumulation of pus. Hemothorax is the accumulation of blood in the pleural cavity.

Question 17

Which respiratory condition is a viral infection that occurs most commonly during the colder months?
A) croup
B) diphtheria
C) influenza
D) pertussis

Accepted Answer

Influenza or the "flu" is a respiratory condition caused by a viral infection that commonly occurs during the colder months. Croup, diphtheria, and pertussis are also respiratory conditions but are caused by different types of infections, and their occurrence is not limited to the colder months.

Question 18

Which procedure is a surgical incision of the pharynx?
A) pharyngoplasty
B) pharyngotomy
C) tracheostomy
D) tracheotomy

Accepted Answer

Pharyngotomy is a surgical incision of the pharynx. Pharyngoplasty is a surgical procedure to repair or reconstruct the pharynx. Tracheostomy and tracheotomy are surgical procedures that involve creating an opening in the trachea, not the pharynx.

Question 19

In ____ the lung fails to expand,because air cannot pass beyond the bronchioles that are blocked by secretions.
A) atelectasis
B) empyema
C) hemothorax
D) pleurisy

Accepted Answer

Atelectasis is a condition in which the lung fails to expand properly. It occurs when the bronchioles are blocked by secretions or other obstructions, preventing air from reaching the alveoli. This can result in collapsed lung tissue and impaired gas exchange. Empyema, hemothorax, and pleurisy all involve inflammation or fluid accumulation in the pleural space surrounding the lungs, but do not directly affect air flow within the bronchioles.

Question 20

Which structure carries both food and air?
A) esophagus
B) nasopharynx
C) oropharynx
D) trachea

Accepted Answer

The oropharynx is part of the throat that serves as a passageway for both food and air.
