Which of the following statements should the provider offer to the patient? "Spend time outside, especially in spring and fall" "Avoid secondhand smoke" "Pets reduce stress and decrease attack." "Vigorous exercise will prevent attacks"

"Avoid secondhand smoke"

At what age does a fetus have fully functional lungs (though its respiratory system is still underdeveloped)? 40 weeks 28 weeks 8 weeks 1 week

28 weeks

Regarding the physiology of the lungs, the right lung has ____ lobes, while the left lung has ____. 2 ... 4 2 ... 2 3 ... 2 1 ... 1

3 ... 2

In triage, a healthcare provider reviews vital signs for a group of patients. Which patient's rate would cause immediate concern? Child with a rate of 30 breaths per minute Toddler with a rate of 50 breaths per minute Adult with a rate of 24 breaths per minute Teenager with a rate of 12 breaths per minute

Adult with a rate of 24 breaths per minute

A healthcare provider is caring for a patient with respiratory zone insufficiencies. The provider understands that the respiratory zone involves the ____. Larynx Naris Trachea Alveoli

Alveoli

Gas exchange in the lungs is accomplished through the capillaries into the Bronchioles Alveoli Diaphragm Bronchi

Alveoli

The body compensates for excessive carbon dioxide to return to homeostasis. Place in order the steps that occur when the carbon dioxide level is too high.

Carbon dioxide crosses the blood brain barrier Increased level of hydrogen ions Blood pH decreases Chemoreceptors stimulate the respiratory center Respiratory rate increases

Which factor is the primary stimulus for breathing? Oxygen levels Limbic system Blood pH Carbon dioxide levels

Carbon dioxide levels

When the diaphragm contracts, what is the result? Decreased thoracic cavity volume Air exits the lungs Increased pulmonary pressure Decreased intrapulmonary pressure

Decreased intrapulmonary pressure

A patient presents to the healthcare provider with hyperventilation. The provider understands that the body responds initially to high carbon dioxide levels when: Respiratory rate increases Chemoreceptors stimulate the respiratory center Hydrogen ion levels increase Carbon dioxide crosses the blood-brain barrier Blood pH decreases

Hydrogen ion levels increase

A healthcare provider assesses a patient who lives in an area of high altitude. The healthcare provider reasons that the patient's blood will contain more erythrocytes, and their breathing pattern will most likely be classified as: Hyperpnea Hypoventilation Hyperventilation Hypertussic

Hyperpnea

Which parts of the central nervous system are involved in respiration? Pineal gland, amygdala, and hippocampus Thalamus, occipital lobe, and frontal lobe Hypothalamus, medulla, and pons Temporal lobe, parietal lobe, and cerebral cortex

Hypothalamus, medulla, and pons

A healthcare provider is caring for an elderly patient. The provider understands that all of the below factors have a negative impact on his patient's respiratory status except: Decreased lung volume Increased tidal volume Increased residual volume Loss of lung elasticity

Increased tidal volume

What is the difference between Internal and External Respiration? External is between the intrapleural space and the alveoli for gas exchange Internal respiration is between the tissues and blood on a cellular level External respiration is between the respiratory membrane and the lungs Internal respiration is between the pleura and the lungs as they expand with air

Internal respiration is between the tissues and blood on a cellular level

Which of the following is a result of hyperventilation? Internal respiration equals external respiration Low levels of Carbon dioxide in the blood, and thus respiratory alkalosis High levels of Carbon dioxide in the blood, and thus respiratory acidosis Respiratory membranes become flooded with Calcium ions

Low levels of Carbon dioxide in the blood, and thus respiratory alkalosis

A patient presents to the emergency room with a thoracic puncture wound. The healthcare provider notes that the wound has not breached the mesentery surrounding the lungs, which is known as the: Placenta Peritoneum Perineum Pleura

Pleura

The only artery in the body that carries truly deoxygenated blood is the ____ because it contains blood that has not yet gone through the pulmonary circuit. Pulmonary Carotid Aorta Vena cava

Pulmonary

Which respiratory volume is not included in determining a patient's vital capacity? Inspiratory reserve volume Tidal volume Residual volume Expiratory reserve volume

Residual volume

A healthcare provider is assessing an infant with respiratory issues. The provider reasons that there is a chance the infant is not making enough ____, a lipoprotein in the alveolar space that reduces surface tension in the lungs. Edema Glycoproteins Surfactant Capillaries

Surfactant

What is the function of the diaphragm in terms of the physical act of breathing? To pull the lungs upwards with each inhalation To exert negative pressure on the lungs To push the lungs downwards with each exhalation To expand the lungs with positive pressure

To exert negative pressure on the lungs

A patient presents to the healthcare provider with a sore throat and laryngitis. The provider understands that inflammation of the larynx is essential to monitor since it leads into the ____ and provides a passageway for air towards the lungs. Alveoli Bronchi Pharynx Trachea

Trachea

The bronchial tree begins with the ____ and terminates in the ____. Pharynx ... lungs Trachea ... alveoli Esophagus ... stomach Epiglottis ... bronchioles

Trachea ... alveoli

Which of the following shows the correct pathway of Respiration? nasal cavity - pharynx - larynx - trachea - bronchi epiglottis - glottis - esophagus - bronchi - alveoli nasal cavity - bronchi - larynx - pharynx - alveoli larynx - pharynx - bronchi - bronchioles - alveoli

nasal cavity - pharynx - larynx - trachea - bronchi

Perfusion refers to: the amount of gas exchange occurring in the respiratory zone the movement of air into and out of the lungs the number of respirations during intense exercise the flow of blood in the pulmonary capillaries

the flow of blood in the pulmonary capillaries

What is the function of respiratory mucosa? to allow lymph to contact the oral cavity to pass air through the esophagus to provide protection for the vocal cords to filter, moisten, and warm incoming air

to filter, moisten, and warm incoming air
