PN 150 PrepU 19

A patient is concerned about his inability to speak clearly due to an infection in the upper respiratory system. Which structure serves as the patient's resonating chamber in speech? Trachea Pharynx Paranasal sinuses Larynx

Paranasal sinuses

What would the critical care nurse recognize as a condition that may indicate a client's need to have a tracheostomy? A client has a respiratory rate of 10 breaths per minute. A client requires permanent ventilation. A client exhibits symptoms of dyspnea. A client has respiratory acidosis.

A client requires permanent ventilation.

The nurse is caring for a client admitted with an acute exacerbation of chronic obstructive pulmonary disease. During assessment, the nurse finds that the client is experiencing increased dyspnea. What is the most accurate measurement of the concentration of oxygen in the client's blood? A capillary blood sample Pulse oximetry An arterial blood gas (ABG) study A complete blood count (CBC)

An arterial blood gas (ABG) study (ABG studies aid in assessing the ability of the lungs to provide adequate oxygen and remove carbon dioxide and the ability of the kidneys to reabsorb or excrete bicarbonate ions to maintain normal body pH.)

The nurse has assessed a client's family history for three generations. The presence of which respiratory disease would justify this type of assessment? Asthma Obstructive sleep apnea Community-acquired pneumonia Pulmonary edema

Asthma

The nurse is assessing a client who has a chest tube in place for the treatment of a pneumothorax. The nurse observes that the water level in the water seal rises and falls in rhythm with the client's respirations. How should the nurse best respond to this assessment finding? Gently reinsert the chest tube 1 to 2 cm and observe if the water level stabilizes. Inform the physician promptly that there is in imminent leak in the drainage system. Encourage the client to do deep breathing and coughing exercises. Document that the chest drainage system is operating as it is intended.

Document that the chest drainage system is operating as it is intended.

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 Aspiration of the fluid that has accumulated around the lungs Injection of radioactive dye to measure the integrity of the lung's blood flow Inspection and examination of the larynx, trachea, and bronchi

Exploration and biopsy of the lymph nodes that drain the lungs

The nurse has instructed a client on how to perform pursed-lip breathing. The nurse recognizes the purpose of this type of breathing is to accomplish which result? Promote more efficient and controlled ventilation and to decrease the work of breathing Improve oxygen transport; induce a slow, deep breathing pattern; and assist the client to control breathing Promote the strengthening of the client's diaphragm Promote the client's ability to take in oxygen

Improve oxygen transport; induce a slow, deep breathing pattern; and assist the client to control breathing

A critical care nurse is caring for a client with an endotracheal tube who is on a ventilator. The nurse knows that meticulous airway management of this client is necessary. What is the main rationale for this? Maintaining a patent airway Preventing the need for suctioning Maintaining the sterility of the client's airway Increasing the client's lung compliance

Maintaining a patent airway

The nurse is caring for a client who has a pleural effusion and who underwent a thoracoscopic procedure earlier in the morning. The nurse should prioritize assessment for which of the following? Sputum production Shortness of breath Throat discomfort Epistaxis

SOB (Follow-up care in the health care facility and at home involves monitoring the client for shortness of breath (which might indicate a pneumothorax). All of the listed options are relevant assessment findings, but shortness of breath is the most serious complication.)

The nurse should convey which information to a client prior to a pulmonary function test? Select all that apply. The client should not eat 2 hours prior to the test. The client should wear loose-fitting clothing. The client will be reclining during the test. The client may be tired after the test. The client will receive contrast medium via catheter.

The client should not eat 2 hours prior to the test. The client should wear loose-fitting clothing. The client may be tired after the test.

The nurse suctions a patient through the endotracheal tube for 20 seconds and observes dysrhythmias on the monitor. What does the nurse determine is occurring with the patient? The patient is hypoxic from suctioning. The patient is having a stress reaction. The patient is having a myocardial infarction. The patient is in a hypermetabolic state.

The patient is hypoxic from suctioning.

A client is exhibiting signs of a pneumothorax following tracheostomy. The surgeon inserts a chest tube into the anterior chest wall. What should the nurse tell the family is the primary purpose of this chest tube? To remove air from the pleural space To drain copious sputum secretions To monitor bleeding around the lungs To assist with mechanical ventilation

To remove air from the pleural space

A nurse is discussing squamous epithelial cells lining each alveolus, which consist of different types of cells. Which type of alveolar cells produce surfactant? Type I cells Type II cells Type III cells Type IV cells

Type II cells

The ED nurse is assessing a client complaining of dyspnea. The nurse auscultates the clent's chest and hears wheezing throughout the lung fields. What might this indicate about the client? A narrowed airway. Pneumonia. The need for physiotherapy. Hemothorax.

a narrowed airway

The nurse is performing a respiratory assessment of a client who has been experiencing episodes of hypoxia. The nurse is aware that this is ultimately attributable to impaired gas exchange. On what factor does adequate gas exchange primarily depend? An appropriate perfusion-diffusion ratio An adequate ventilation-perfusion ratio Adequate diffusion of gas in shunted blood Appropriate blood nitrogen concentration

an adequate ventilation-perfusion ratio

A client is undergoing a thoracentesis. Which nursing action will the nurse perform following the procedure? Maintain the client on bed rest for several hours. Ambulate the client following the procedure. Instruct the client to cough forcefully every ten minutes. Place the client in a supine position

maintain the client on bed rest for several hours

A nurse is educating a client in anticipation of a procedure that will require a water-sealed chest drainage system. What should the nurse tell the client and the family that this drainage system is used for? Maintaining positive chest-wall pressure Monitoring pleural fluid osmolarity Providing positive intrathoracic pressure Removing excess air and fluid

remove excess air and fluid

Which type of ventilator has a preset volume of air to be delivered with each inspiration? Negative pressure Volume cycled Time cycled Pressure cycled

volume cycled
