Explanation:
A physician usually performs a thoracentesis when the client is sitting in a chair or on the edge of the bed, with the legs supported and the arms

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

Warm and humidify inspired air
Correct
Explanation:
The vascular and ciliated mucous lining of the nasal cavities warms and humidifies inspired air. It is the function of the cilia alone to move mucus in the nasal cavities and filter the inspired air.

You are the hospice nurse caring for a client with pulmonary fibrosis who wants to die at home. The client is having difficulty breathing. The family asks why it is so hard for the client to breathe. What would be the nurse's best response?

The fibrosis of the lungs makes the lungs stiff, which makes it harder to breathe.
Correct
Explanation:
Decreased surfactant, fibrosis, edema, and atelectasis (alveolar collapse) affect lung compliance. Greater pressure gradients are needed when lungs ar

Your client has just had an invasive procedure to assess the respiratory system. What do you know should be assessed on this client?

Respiratory distress
Correct
Explanation:
After invasive procedures, the nurse must carefully check for signs of respiratory distress and blood-streaked sputum. Masses in the pleural space are a condition that affects fremitus. General examination of over

A nonverbal client has just finished undergoing a bronchoscopy procedure and writes that he want to eat lunch now. Which intervention is necessary for the nurse to complete at this time?

Assess for a cough reflex.
Correct
Explanation:
Before a bronchoscopy procedure, the nurse will administer preoperative medications, usually atropine and a sedative. These are prescribed to inhibit vagal stimulation, suppress the cough reflex, sedate the

Upon palpation of the sinus area, what would the nurse identify as a normal finding?

No sensation during palpation
Explanation:
Sinus assessment involves using the thumbs to apply gentle pressure in an upward fashion at the sinuses. Tenderness suggests inflammation. The sinuses can be inspected by transillumination, where a light is passe

An 83-year-old client was originally admitted for surgery and has suffered multiple postoperative complications. The pulmonologist has scheduled a thoracentesis to obtain a sample of pleural fluid or a biopsy specimen from the pleural wall for diagnostic

Inflammation
Explanation:
A thoracentesis may be performed to obtain a sample of pleural fluid or to biopsy a specimen from the pleural wall for diagnostic purposes. Serous fluid may be associated with cancer, inflammatory conditions, or heart failure.

Which of the following results in decreased gas exchange in older adults?

The alveolar walls contain fewer capillaries.
Explanation:
Although the number of alveoli remains stable with age, the alveolar walls become thinner and contain fewer capillaries, resulting in decreased gas exchange. The lungs also lose elasticity and bec

During a routine visit to the pulmonologist, a client is told to undergo a mediastinoscopy. After the physician leaves the room, the nurse enters and is asked about this procedure. How should the nurse respond?

Exploration and biopsy of the lymph nodes that drain the lungs
Correct
Explanation:
A mediastinoscopy is the endoscopic examination of the mediastinum for exploration and biopsy of mediastinal lymph nodes that drain the lungs. The remaining options are ex

n which position should the patient be placed for a thoracentesis?

Sitting on the edge of the bed
Explanation:
If possible place the patient upright or sitting on the edge of the bed with the feet supported and arms and head on a padded over-the-bed table. Other positions in which the patient could be placed include stra

Which assessment finding would be most consistent with advanced emphysema?

Barrel-shaped chest
Correct
Explanation:
Barrel chest occurs as result of overinflation of the lungs. In a client with emphysema, the ribs are more widely spaced and the intercostal spaces tend to bulge on expiration. The apprearance of a such a client wi

The nursing instructor is talking with senior nursing students about diagnostic procedures used in respiratory diseases. The instructor discusses thoracentesis, defining it as a procedure performed for diagnostic purposes or to aspirate accumulated excess

nfection
Explanation:
A small amount of fluid lies between the visceral and parietal pleurae. When excess fluid or air accumulates, the physician aspirates it from the pleural space by inserting a needle into the chest wall. This procedure, called thorace

Which ventilation-perfusion ratio is exhibited by a pulmonary emboli?

Dead space
Explanation:
When ventilation exceeds perfusion a dead space exists. An example of a dead space is pulmonary emboli. A low ventilation-perfusion ratio exists in pneumonia or with a mucus plug. A silent unit occurs in pneumothorax or ARDS.

A son brings his father into the clinic, stating that his father's color has changed to bluish around the mouth. The father is confused, with a respiratory rate of 28 breaths per minute and scattered crackles throughout. The son states this condition just

Cyanosis
Explanation:
The client's appearance may give clues to respiratory status. Cyanosis, a bluish coloring of the skin, is a very late indicator of hypoxia. The presence of cyanosis is from decreased unoxygenated hemoglobin. In the presence of a pulm

Which of the following is a deformity of the chest that occurs as a result of over inflation of the lungs?

Explanation:
A barrel chest occurs as a result of over inflation of the lungs. There is an increase in the anteroposterior diameter of the thorax. Funnel chest occurs when there is a depression in the lower portion of the sternum, which may r

Which of the following alveolar cells secrete surfactant?

Type II
Explanation:
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 wal

A nurse is concerned that a client may develop postoperative atelectasis. Which nursing diagnosis would be most appropriate if this complication occurs?

Impaired gas exchange
Explanation:
Airflow is decreased with atelectasis, which is a bronchial obstruction from collapsed lung tissue. If there is an obstruction, there is limited or no gas exchange in this area. Impaired gas exchange is thus the most lik

Pink frothy sputum may be an indication of

pulmonary edema.
Explanation:
Profuse, frothy pink material, often welling up into the throat, may indicate pulmonary edema. Foul-smelling sputum and bad breath may indicate a lung abscess, bronchiectasis, or an infection caused by fusospirochetal or othe

A client with chronic bronchitis is admitted with an exacerbation of symptoms. During the nursing assessment, the nurse will expect which of the following findings? Select all that apply.
