Chapter 25 - The Respiratory System Flashcards
What carries nerve impulses to the brain?
Olfactory nerve (CN I).
What provides resonance for the voice?
Sinuses.
What connects the nasopharynx to the middle ear?
Auditory tubes.
What guards the entrance of the larynx?
Epiglottis.
What is the correct sequence of the respiratory system organs?
- Nasal cavity
- Nasopharynx
- Epiglottis
- Larynx
- Trachea
- Alveolar sac
A client is having difficulty with diaphragmatic breathing because of the discomfort from upper abdominal surgery. Which describes the function of the diaphragm?
It separates the thoracic from the abdominal activity.
A student nurse is learning new terminology about the respiratory system. What is surfactant?
A chemical that lines the walls of the alveoli.
While describing the exchange of gases in the body. How will the nurse explain the formation of carbonic acid (H2CO3)?
Reaction to the carbon dioxide with water.
There are several protective respiratory reflexes in the human body. Which are the protective respiratory reflexes?
Yawning, sneezing, and coughing.
Why should the nurse encourage clients to perform deep-breathing exercises?
To improve oxygen delivery to the lungs and tissues.
A client’s blood gas results indicate respiratory acidosis. Which are the causes of respiratory acidosis?
Emphysema, Asthma, severe pneumonia.
A nurse is reviewing a client the function of the pleura. What is the function of the pleura?
To allow lungs to move without causing any pain or friction against the chest walls.
A client with severe COPD has difficulty maintaining homeostasis during breathing. How is homeostasis maintained during respiration?
Interactions between the respiratory and renal systems.
The client is a miner and many of the hairs of the nostril have been destroyed over the years in this occupation. What is the function of the hairs in the nostril?
To filter air and remove foreign particles to prevent them from entering the lungs.
A client’s oropharynx is inflamed. What is the function of the oropharynx?
It carries food to the esophagus and air to the trachea.
A client has a defective cranial nerve I. Which data would the nurse gather in order to determine function?
Instruct the client to smell and identify a variety of scents.
A client is eating supper and begins coughing. Which action should the nurse take first?
Do nothing. Coughing will usually dislodge the foreign body.
The rescue squad brings into the emergency department a client who has a blocked airway after choking on a piece of steak. The client is unresponsive, and resuscitation efforts are continued with a bag valve mask. Which action by the nurse is a priority?
Gather equipment for an emergency tracheotomy.
The nurse is caring for a client with left lower lobe pneumonia. Which nursing action would assist in improving oxygen delivery to the lungs and tissues?
Encourage frequent coughing and deep breathing.
