Eustachian tubes *The nasopharynx contains the adenoids and openings of the eustachian tubes. The eustachian tubes connect the pharynx to the middle ear and are the means by which upper respiratory infections spread to the middle ear. The client's infection is not caused by genetics. The oropharynx contains the tongue. The epiglottis closes during swallowing and relaxes during respiration.

Kussmaul respirations *Kussmaul respirations are seen in patients with diabetic ketoacidosis. In Cheyne-Stokes respiration, rate and depth increase, then decrease until apnea occurs.

When assessing a client, which adaptation indicates the presence of respiratory distress?

Orthopnea

The nurse is performing an assessment for a patient with congestive heart failure. The nurse asks if the patient has difficulty breathing in any position other than upright. What is the nurse referring to?

Orthopnea *Orthopnea (inability to breathe easily except in an upright position) may be found in patients with heart disease and occasionally in patients with chronic obstructive pulmonary disease (COPD). Dyspnea (subjective feeling of difficult or labored breathing, breathlessness, shortness of breath) is a multidimensional symptom common to many pulmonary and cardiac disorders, particularly when there is decreased lung compliance or increased airway resistance. Tachypnea is abnormally rapid respirations. Bradypnea is abnormally slow respirations.

The nurse answers the call light of a male patient. The patient is complaining of an irritating tickling sensation in the throat, a salty taste, and a burning sensation in the chest.

The lungs

The body of a critically ill client may use which of the following homeostatic mechanisms to maintain normal pH?

The lungs eliminate carbonic acid by blowing off more CO2. *To maintain normal pH in critically ill clients, the lungs eliminate carbonic acid by blowing off more CO2. To maintain normal pH in critically ill clients, the lungs conserve CO2 by slowing respiratory volume. This is the way the body would compensate during an acid-base imbalance in cases of metabolic alkalosis. This is the way the body would compensate during an acid-base imbalance in cases of metabolic acidosis.

The client is returning from the operating room following a broncho scopy. Which action, performed by the nursing assistant, would the nurse stop if began prior to nursing assessment?

The nursing assistant is pouring a glass of water to wet the client's mouth.

A client experiences a head injury in a motor vehicle accident. The client's level of consciousness is declining, and respirations have become slow and shallow. When monitoring a client's respiratory status, which area of the brain would the nurse realize is responsible for the rate and depth?

The pons *The pons in the brainstem controls rate and depth of respirations. When injury occurs or increased intracranial pressure results, respirations are slowed. The frontal lobe completes executive functions and cognition. The central sulcus is a fold in the cerebral cortex called the central fissure. The Wernicke's area is the area linked to speech.

An 18-year-old male client is described as having pectus carinatum. The nurse is aware that the manifestation of this condition would be:

The sternum protrudes and the ribs are sloped backward.

The nurse is caring for a client diagnosed with asthma. While performing the shift assessment, the nurse auscultates breath sounds including sibilant wheezes, which are continuous musical sounds. What characteristics describe sibilant wheezes?

They can be heard during inspiration and expiration.

The volume of air inhaled and exhaled with each breath is termed which of the following?

Tidal volume

The instructor of the pre-nursing physiology class is explaining respiration to the class. What does the instructor explain is the main function of respiration?

To exchange oxygen and CO2 between the atmospheric air and the blood and between the blood and the cells

Knowing respiratory physiology is important to understand how the disease process can work within that system. Which hollow tube transports air from the laryngeal pharynx to the bronchi?

Trachea

Which of the following alveolar cells secrete surfactant?

Type II *Type II alveolar cells are metabolically active and secrete surfactant, a phospholipid that decrease the surface tension in the alveoli and prevents their collapse. Type I alveolar cells are epithelial cells that form the alveolar walls. Type III alveolar cell macrophages are large phagocytic cells that ingest foreign matter and act as an important defense mechanism. Type IV is not a category of alveolar cells.

A 53-year-old male is a regular client in the respiratory group where you practice nursing. As with all adults, millions of alveoli form most of the pulmonary mass. The squamous epithelial cells lining each alveolus consist of different types of cells. Which type of the alveoli cells produce surfactant?

Type II cells

A nurse caring for a patient with a pulmonary embolism understands that a high ventilation-perfusion ratio may exist. What does this mean for the patient?

Ventilation exceeds perfusion.

You are caring for a 65-year-old client who has been newly diagnosed with emphysema. The client is confused by the new terms and wants to know what ventilation means. Which of the following can instruct this client?

Ventilation is breathing air in and out of the lungs.

What is the difference between respiration and ventilation?

Ventilation is the movement of air in and out of the respiratory tract.

The nurse documents breath sounds that are soft, with inspiratory sounds longer than expiratory and found over the periphery of the lungs. Which of the following will the nurse chart?

Vesicular

The nursing instructor is teaching a pre-nursing pathophysiology class. The class is covering the respiratory system. The instructor explains that the respiratory system is comprised of both the upper and lower respiratory system. The nose is part of the upper respiratory system. The instructor continues to explain that the nasal cavities have a vascular and ciliated mucous lining. What is the purpose of the vascular and ciliated mucous lining of the nasal cavities?

Warm and humidify inspired air

Wheezes

The nurse is performing chest auscultation for a patient with asthma. How does the nurse describe the high-pitched, sibilant, musical sounds that are heard?

Wheezes

While auscultating the lungs of a client with asthma, the nurse hears a continuous, high-pitched whistling sound on expiration. The nurse will document this sound as which of the following?

Wheezes *Wheezes, usually heard on expiration, are continuous, musical, high pitched, and whistle-like sounds caused by air passing through narrowed airways. Often, wheezes are associated with asthma.

A nurse is preparing a client with a pleural effusion for a thoracentesis. The nurse should:

assist the client to a sitting position on the edge of the bed, leaning over the bedside table.

A black client with asthma seeks emergency care for acute respiratory distress. Because of this client's dark skin, the nurse should assess for cyanosis by inspecting the:

mucous membranes. *Skin color doesn't affect the mucous membranes. Therefore, the nurse can assess for cyanosis by inspecting the client's mucous membranes. The lips, nail beds, and earlobes are less-reliable indicators of cyanosis because they're affected by skin color.

The nurse auscultates lung sounds that are harsh and cracking, sounding like two pieces of leather being rubbed together. The nurse would be correct in documenting this finding as

pleural friction rub. *A pleural friction rub is heard secondary to inflammation and loss of lubricating pleural fluid. Crackles are soft, high-pitched, discontinuous popping sounds that occur during inspiration. Sonorous wheezes are deep, low-pitched rumbling sounds heard primarily during expiration. Sibilant wheezes are continuous, musical, high-pitched, whistlelike sounds heard during inspiration and expiration.

Pink frothy sputum may be an indication of

pulmonary edema.

The term for the volume of air inhaled and exhaled with each breath is

tidal volume.
