Oxygenation Practice Questions

The clinic nurse is caring for a patient who has been diagnosed with emphysema and who has just had a pulmonary function test (PFT) ordered. The patient asks, What exactly is this test for? What would be the nurses best response? A) A PFT measures how much air moves in and out of your lungs when you breathe. B) A PFT measures how much energy you get from the oxygen you breathe. C) A PFT measures how elastic your lungs are. D) A PFT measures whether oxygen and carbon dioxide move between your lungs and your blood.

A) A PFT measures how much air moves in and out of your lungs when you breathe. PFTs are routinely used in patients with chronic respiratory disorders. They are performed to assess respiratory function and to determine the extent of dysfunction. Such tests include measurements of lung volumes, ventilatory function, and the mechanics of breathing, diffusion, and gas exchange. Lung elasticity and diffusion can often be implied from PFTs, but they are not directly assessed. Energy obtained from respiration is not measured directly.

The nurse at a long-term care facility is assessing each of the residents. Which resident most likely faces the greatest risk for aspiration? A) A resident who suffered a severe stroke several weeks ago B) A resident with mid-stage Alzheimers disease C) A 92-year-old resident who needs extensive help with ADLs D) A resident with severe and deforming rheumatoid arthritis

A) A resident who suffered a severe stroke several weeks ago Aspiration may occur if the patient cannot adequately coordinate protective glottic, laryngeal, and cough reflexes. These reflexes are often affected by stroke. A patient with mid-stage Alzheimers disease does not likely have the voluntary muscle problems that occur later in the disease. Clients that need help with ADLs or have severe arthritis should not have difficulty swallowing unless it exists secondary to another problem.

You are providing care for a patient who has a diagnosis of pneumonia attributed toStreptococcus pneumonia infection. Which of the following aspects of nursing care would constitute part of the planning phase of the nursing process? A) Achieve SaO2 92% at all times. B) Auscultate chest q4h. C) Administer oral fluids q1h and PRN. D) Avoid overexertion at all times.

A) Achieve SaO2 92% at all times. The planning phase entails specifying the immediate, intermediate, and long-term goals of nursing action, such as maintaining a certain level of oxygen saturation in a patient with pneumonia. Providing fluids and avoiding overexertion are parts of the implementation phase of the nursing process. Chest auscultation is an assessment.

Postural drainage has been ordered for a patient who is having difficulty mobilizing her bronchial secretions. Before repositioning the patient and beginning treatment, the nurse should perform what health assessment? A) Chest auscultation B) Pulmonary function testing C) Chest percussion D) Thoracic palpation

A) Chest auscultation Chest auscultation should be performed before and after postural drainage in order to evaluate the effectiveness of the therapy. Percussion and palpation are less likely to provide clinically meaningful data for the nurse. PFTs are normally beyond the scope of the nurse and are not necessary immediately before postural drainage.

A nurse is working with a child who is undergoing a diagnostic workup for suspected asthma. What are the signs and symptoms that are consistent with a diagnosis of asthma? Select all that apply. A) Chest tightness B) Crackles C) Bradypnea D) Wheezing E) Cough

A) Chest tightness D) Wheezing E) Cough Asthma is a chronic inflammatory disease of the airways that causes airway hyperresponsiveness, mucosal edema, and mucus production. This inflammation ultimately leads to recurrent episodes of asthma symptoms: cough, chest tightness, wheezing, and dyspnea. Crackles and bradypnea are not typical symptoms of asthma.

A nurse is caring for a patient who has been admitted with an exacerbation of chronic bronchiectasis. The nurse should expect to assess the patient for which of the following clinical manifestations? A) Copious sputum production B) Pain on inspiration C) Pigeon chest D) Dry cough

A) Copious sputum production Clinical manifestations of bronchiectasis include hemoptysis, chronic cough, copious purulent sputum, and clubbing of the fingers. Because of the copious production of sputum, the cough is rarely dry. A pigeon chest is not associated with the disease and patients do not normally experience pain on inspiration.

The perioperative nurse is writing a care plan for a patient who has returned from surgery 2 hours prior. Which measure should the nurse implement to most decrease the patients risk of developing pulmonary emboli (PE)? A) Early ambulation B) Increased dietary intake of protein C) Maintaining the patient in a supine position D) Administering aspirin with warfarin

A) Early ambulation For patients at risk for PE, the most effective approach for prevention is to prevent deep vein thrombosis. Active leg exercises to avoid venous stasis, early ambulation, and use of elastic compression stocking are general preventive measures. The patient does not require increased dietary intake of protein directly related to prevention of PE, although it will assist in wound healing during the postoperative period. The patient should not be maintained in one position, but frequently repositioned, unless contraindicated by the surgical procedure. Aspirin should never be administered with warfarin because it will increase the patients risk for bleeding.

The medical nurse who works on a pulmonology unit is aware that several respiratory conditions can affect lung tissue compliance. The presence of what condition would lead to an increase in lung compliance? A) Emphysema B) Pulmonary fibrosis C) Pleural effusion D) Acute respiratory distress syndrome (ARDS)

A) Emphysema High or increased compliance occurs if the lungs have lost their elasticity and the thorax is overdistended, in conditions such as emphysema. Conditions associated with decreased compliance include pneumothorax, hemothorax, pleural effusion, pulmonary edema, atelectasis, pulmonary fibrosis,

The nurse is caring for a patient with a lower respiratory tract infection. When planning a focused respiratory assessment, the nurse should know that this type of infection most often causes what? A) Impaired gas exchange B) Collapsed bronchial structures C) Necrosis of the alveoli D) Closed bronchial tree

A) Impaired gas exchange The lower respiratory tract consists of the lungs, which contain the bronchial and alveolar structures needed for gas exchange. A lower respiratory tract infection does not collapse bronchial structures or close the bronchial tree. An infection does not cause necrosis of lung tissues.

The nurse is caring for a patient at risk for atelectasis. The nurse implements a first-line measure to prevent atelectasis development in the patient. What is an example of a first-line measure to minimize atelectasis? A) Incentive spirometry B) Intermittent positive-pressure breathing (IPPB) C) Positive end-expiratory pressure (PEEP) D) Bronchoscopy

A) Incentive spirometry Strategies to prevent atelectasis, which include frequent turning, early ambulation, lung-volume expansion maneuvers (deep breathing exercises, incentive spirometry), and coughing, serve as the first-line measures to minimize or treat atelectasis by improving ventilation. In patients who do not respond to first-line measures or who cannot perform deep-breathing exercises, other treatments such as positive end-expiratory pressure (PEEP), continuous or intermittent positive-pressure breathing (IPPB), or bronchoscopy may be used.

A critical-care nurse is caring for a patient diagnosed with pneumonia as a surgical complication. The nurses assessment reveals that the patient has an increased work of breathing due to copious tracheobronchial secretions. What should the nurse encourage the patient to do? A) Increase oral fluids unless contraindicated. B) Call the nurse for oral suctioning, as needed. C) Lie in a low Fowlers or supine position. D) Increase activity.

A) Increase oral fluids unless contraindicated. The nurse should encourage hydration because adequate hydration thins and loosens pulmonary secretions. Oral suctioning is not sufficiently deep to remove tracheobronchial secretions. The patient should have the head of the bed raised, and rest should be promoted to avoid exacerbation of symptoms.

A nurse has been asked to give a workshop on COPD for a local community group. The nurse emphasizes the importance of smoking cessation because smoking has what pathophysiologic effect? A) Increases the amount of mucus production B) Destabilizes hemoglobin C) Shrinks the alveoli in the lungs D) Collapses the alveoli in the lungs

A) Increases the amount of mucus production Smoking irritates the goblet cells and mucous glands, causing an increased accumulation of mucus, which, in turn, produces more irritation, infection, and damage to the lung.

The nurse is caring for a patient who needs education on his medication therapy for allergic rhinitis. The patient is to take cromolyn (Nasalcrom) daily. In providing education for this patient, how should the nurse describe the action of the medication? A) It inhibits the release of histamine and other chemicals. B) It inhibits the action of proton pumps. C) It inhibits the action of the sodium-potassium pump in the nasal epithelium. D) It causes bronchodilation and relaxes smooth muscle in the bronchi.

A) It inhibits the release of histamine and other chemicals. Cromolyn (Nasalcrom) inhibits the release of histamine and other chemicals. It is prescribed to treat allergic rhinitis. Beta-adrenergic agents lead to bronchodilation and stimulate beta-2adrenergic receptors in the smooth muscle of the bronchi and bronchioles. It does not affect proton pump action or the sodium-potassium pump in the nasal cells.

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 patient is necessary. What is the main rationale for this? A) Maintaining a patent airway B) Preventing the need for suctioning C) Maintaining the sterility of the patients airway D) Increasing the patients lung compliance

A) Maintaining a patent airway Maintaining a patent (open) airway is achieved through meticulous airway management, whether in an emergency situation such as airway obstruction or in long-term management, as in caring for a patient with an endotracheal or a tracheostomy tube. The other answers are incorrect.

The nurse is assessing an adult patient following a motor vehicle accident. The nurse observes that the patient has an increased use of accessory muscles and is complaining of chest pain and shortness of breath. The nurse should recognize the possibility of what condition? A) Pneumothorax B) Anxiety C) Acute bronchitis D) Aspiration

A) Pneumothorax If the pneumothorax is large and the lung collapses totally, acute respiratory distress occurs. The patient is anxious, has dyspnea and air hunger, has increased use of the accessory muscles, and may develop central cyanosis from severe hypoxemia. These symptoms are not definitive of pneumothorax, but because of the patients recent trauma they are inconsistent with anxiety, bronchitis, or aspiration.

The nurse is caring for a patient who has returned to the unit following a bronchoscopy. The patient is asking for something to drink. Which criterion will determine when the nurse should allow the patient to drink fluids? A) Presence of a cough and gag reflex B) Absence of nausea C) Ability to demonstrate deep inspiration D) Oxygen saturation of 92%

A) Presence of a cough and gag reflex After the procedure, it is important that the patient takes nothing by mouth until the cough reflex returns because the preoperative sedation and local anesthesia impair the protective laryngeal reflex and swallowing for several hours. Deep inspiration, adequate oxygen saturation levels, and absence of nausea do not indicate that oral intake is safe from the risk of aspiration.

The nurse has admitted a patient who is scheduled for a thoracic resection. The nurse is providing preoperative teaching and is discussing several diagnostic studies that will be required prior to surgery. Which study will be performed to determine whether the planned resection will leave sufficient functioning lung tissue? A) Pulmonary function studies B) Exercise tolerance tests C) Arterial blood gas values D) Chest x-ray

A) Pulmonary function studies Pulmonary function studies are performed to determine whether the planned resection will leave sufficient functioning lung tissue. ABG values are assessed to provide a more complete picture of the functional capacity of the lung. Exercise tolerance tests are useful to determine if the patient who is a candidate for pneumonectomy can tolerate removal of one of the lungs. Preoperative studies, such as a chest x-ray, are performed to provide a baseline for comparison during the postoperative period and to detect any unsuspected abnormalities.

A cardiovascular patient with a previous history of pulmonary embolism (PE) is experiencing a sudden onset of dyspnea, rapid breathing, and chest pain. The nurse recognizes the characteristic signs and symptoms of a PE. What is the nurses best action? A) Rapidly assess the patients cardiopulmonary status. B) Arrange for an ECG. C) Increase the height of the patients bed. D) Manage the patients anxiety.

A) Rapidly assess the patients cardiopulmonary status. Patient management in the event of a PE begins with cardiopulmonary assessment and intervention. This is a priority over ECG monitoring, management of anxiety, or repositioning of the patient, even though each of these actions may be appropriate and necessary.

A patient who is being treated for pneumonia starts complaining of sudden shortness of breath. An arterial blood gas (ABG) is drawn. The ABG has the following values: pH 7.21, PaCO2 64 mm Hg, HCO3 = 24 mm Hg. What does the ABG reflect? A) Respiratory acidosis B) Metabolic alkalosis C) Respiratory alkalosis D) Metabolic acidosis

A) Respiratory acidosis The pH is below 7.40, PaCO2 is greater than 40, and the HCO3 is normal; therefore, it is a respiratory acidosis, and compensation by the kidneys has not begun, which indicates this was probably an acute event. The HCO3 of 24 is within the normal range so it is not metabolic alkalosis. The pH of 7.21 indicates an acidosis, not alkalosis. The pH of 7.21 indicates it is an acidosis but the HCO3 of 24 is within the normal range, ruling out metabolic acidosis.

A patient with emphysema is experiencing shortness of breath. To relieve this patients symptoms, the nurse should assist her into what position? A) Sitting upright, leaning forward slightly B) Low Fowlers, with the neck slightly hyperextended C) Prone D) Trendelenburg

A) Sitting upright, leaning forward slightly The typical posture of a person with COPD is to lean forward and use the accessory muscles of respiration to breathe. Low Fowlers positioning would be less likely to aid oxygenation. Prone or Trendelenburg positioning would exacerbate shortness of breath.

A nurse is admitting a new patient who has been admitted with a diagnosis of COPD exacerbation. How can the nurse best help the patient achieve the goal of maintaining effective oxygenation? A) Teach the patient strategies for promoting diaphragmatic breathing. B) Administer supplementary oxygen by simple face mask. C) Teach the patient to perform airway suctioning. D) Assist the patient in developing an appropriate exercise program.

A) Teach the patient strategies for promoting diaphragmatic breathing. The breathing pattern of most people with COPD is shallow, rapid, and inefficient; the more severe the disease, the more inefficient the breathing pattern. With practice, this type of upper chest breathing can be changed to diaphragmatic breathing, which reduces the respiratory rate, increases alveolar ventilation, and sometimes helps expel as much air as possible during expiration. Suctioning is not normally necessary in patients with COPD. Supplementary oxygen is not normally delivered by simple face mask and exercise may or may not be appropriate.

The ED nurse is assessing a patient complaining of dyspnea. The nurse auscultates the patients chest and hears wheezing throughout the lung fields. What might this indicate? A) The patient has a narrowed airway. B) The patient has pneumonia. C) The patient needs physiotherapy. D) The patient has a hemothorax.

A) The patient has a narrowed airway. Wheezing is a high-pitched, musical sound that is often the major finding in a patient with bronchoconstriction or airway narrowing. Wheezing is not normally indicative of pneumonia or hemothorax. Wheezing does not indicate the need for physiotherapy.

A nurse is planning the care of a client with bronchiectasis. What goal of care should the nurse prioritize? A) The patient will successfully mobilize pulmonary secretions. B) The patient will maintain an oxygen saturation level of 98%. C) The patients pulmonary blood pressure will decrease to within reference ranges. D) The patient will resume prediagnosis level of function within 72 hours.

A) The patient will successfully mobilize pulmonary secretions. Nursing management focuses on alleviating symptoms and helping patients clear pulmonary secretions. Pulmonary pressures are not a central focus in the care of the patient with bronchiectasis. Rapid resumption of prediagnosis function and oxygen saturation above 98% are unrealistic goals.

A nurse educator is reviewing the implications of the oxyhemoglobin dissociation curve with regard to the case of a current patient. The patient currently has normal hemoglobin levels, but significantly decreased SaO2 and PaO2 levels. What is an implication of this physiological state? A) The patients tissue demands may be met, but she will be unable to respond to physiological stressors. B) The patients short-term oxygen needs will be met, but she will be unable to expel sufficient CO2 C) The patient will experience tissue hypoxia with no sensation of shortness of breath or labored breathing. D) The patient will experience respiratory alkalosis with no ability to compensate.

A) The patients tissue demands may be met, but she will be unable to respond to physiological stressors. With a normal hemoglobin level of 15 mg/dL and a PaO2 level of 40 mm Hg (SaO2 75%), there is adequate oxygen available for the tissues, but no reserve for physiological stresses that increase tissue oxygen demand. If a serious incident occurs (e.g., bronchospasm, aspiration, hypotension, or cardiac dysrhythmias) that reduces the intake of oxygen from the lungs, tissue hypoxia results.

A patient 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? A) To remove air from the pleural space B) To drain copious sputum secretions C) To monitor bleeding around the lungs D) To assist with mechanical ventilation

A) To remove air from the pleural space Chest tubes and closed drainage systems are used to re-expand the lung involved and to remove excess air, fluid, and blood. The primary purpose of a chest tube is not to drain sputum secretions, monitor bleeding, or assist with mechanical ventilation.

The nurse is assessing a newly admitted medical patient and notes there is a depression in the lower portion of the patients sternum. This patients health record should note the presence of what chest deformity? A) A barrel chest B) A funnel chest C) A pigeon chest D) Kyphoscoliosis

B) A funnel chest A funnel chest occurs when there is a depression in the lower portion of the sternum, and this may lead to compression of the heart and great vessels, resulting in murmurs. A barrel chest is characterized by an increase in the anteroposterior diameter of the thorax and is a result of overinflation of the lungs. A pigeon chest occurs as a result of displacement of the sternum and includes an increase in the anteroposterior diameter. Kyphoscoliosis, which is characterized by elevation of the scapula and a corresponding S-shaped spine, limits lung expansion within the thorax.

A patient with thoracic trauma is admitted to the ICU. The nurse notes the patients chest and neck are swollen and there is a crackling sensation when palpated. The nurse consequently identifies the presence of subcutaneous emphysema. If this condition becomes severe and threatens airway patency, what intervention is indicated? A) A chest tube B) A tracheostomy C) An endotracheal tube D) A feeding tube

B) A tracheostomy In severe cases in which there is widespread subcutaneous emphysema, a tracheostomy is indicated if airway patency is threatened by pressure of the trapped air on the trachea. The other listed tubes would neither resolve the subcutaneous emphysema nor the consequent airway constriction.

A hospital has been the site of an increased incidence of hospital-acquired pneumonia (HAP). What is an important measure for the prevention of HAP? A) Administration of prophylactic antibiotics B) Administration of pneumococcal vaccine to vulnerable individuals C) Obtaining culture and sensitivity swabs from all newly admitted patients D) Administration of antiretroviral medications to patients over age 65

B) Administration of pneumococcal vaccine to vulnerable individuals Pneumococcal vaccination reduces the incidence of pneumonia, hospitalizations for cardiac conditions, and deaths in the general older adult population. A onetime vaccination of pneumococcal polysaccharide vaccine (PPSV) is recommended for all patients 65 years of age or older and those with chronic diseases. Antibiotics are not given on a preventative basis and antiretroviral medications do not affect the most common causative microorganisms. Culture and sensitivity testing

A nurse is assessing a patient who is suspected of having bronchiectasis. The nurse should consider which of the following potential causes? Select all that apply. A) Pulmonary hypertension B) Airway obstruction C) Pulmonary infections D) Genetic disorders E) Atelectasis

B) Airway obstruction C) Pulmonary infections D) Genetic disorders Bronchiectasis is a chronic, irreversible dilation of the bronchi and bronchioles. Under the new definition of COPD, it is considered a disease process separate from COPD. Bronchiectasis may be caused by a variety of conditions, including airway obstruction, diffuse airway injury, pulmonary infections and obstruction of the bronchus or complications of long-term pulmonary infections, or genetic disorders such as cystic fibrosis. Bronchiectasis is not caused by pulmonary hypertension or atelectasis.

A nurse is caring for a patient who has been hospitalized with an acute asthma exacerbation. What drugs should the nurse expect to be ordered for this patient to gain underlying control of persistent asthma? A) Rescue inhalers B) Anti-inflammatory drugs C) Antibiotics D) Antitussives

B) Anti-inflammatory drugs Because the underlying pathology of asthma is inflammation, control of persistent asthma is accomplished primarily with regular use of anti-inflammatory medications. Rescue inhalers, antibiotics, and antitussives do not aid in the first-line control of persistent asthma.

An interdisciplinary team is planning the care of a patient with bronchiectasis. What aspects of care should the nurse anticipate? Select all that apply. A) Occupational therapy B) Antimicrobial therapy C) Positive pressure isolation D) Chest physiotherapy E) Smoking cessation

B) Antimicrobial therapy D) Chest physiotherapy E) Smoking cessation Chest physiotherapy, antibiotics, and smoking cessation are cornerstones of the care of patients with bronchiectasis. Occupational therapy and isolation are not normally indicated.

A perioperative nurse is caring for a postoperative patient. The patient has a shallow respiratory pattern and is reluctant to cough or to begin mobilizing. The nurse should address the patients increased risk for what complication? A) Acute respiratory distress syndrome (ARDS) B) Atelectasis C) Aspiration D) Pulmonary embolism

B) Atelectasis A shallow, monotonous respiratory pattern coupled with immobility places the patient at an increased risk of developing atelectasis. These specific factors are less likely to result in pulmonary embolism or aspiration. ARDS involves an exaggerated inflammatory response and does not normally result from factors such as immobility and shallow breathing.

The physician has ordered continuous positive airway pressure (CPAP) with the delivery of a patients high-flow oxygen therapy. The patient asks the nurse what the benefit of CPAP is. What would be the nurses best response? A) CPAP allows a higher percentage of oxygen to be safely used. B) CPAP allows a lower percentage of oxygen to be used with a similar effect. C) CPAP allows for greater humidification of the oxygen that is administered. D) CPAP allows for the elimination of bacterial growth in oxygen delivery systems.

B) CPAP allows a lower percentage of oxygen to be used with a similar effect. Prevention of oxygen toxicity is achieved by using oxygen only as prescribed. Often, positive end- expiratory pressure (PEEP) or CPAP is used with oxygen therapy to reverse or prevent microatelectasis, thus allowing a lower percentage of oxygen to be used. Oxygen is moistened by passing through a humidification system. Changing the tubing on the oxygen therapy equipment is the best technique for controlling bacterial growth.

A nurse is developing the teaching portion of a care plan for a patient with COPD. What would be the most important component for the nurse to emphasize? A) Smoking up to one-half of a pack of cigarettes weekly is allowable. B) Chronic inhalation of indoor toxins can cause lung damage. C) Minor respiratory infections are considered to be self-limited and are not treated. D) Activities of daily living (ADLs) should be clustered in the early morning hours.

B) Chronic inhalation of indoor toxins can cause lung damage. Environmental risk factors for COPD include prolonged and intense exposure to occupational dusts and chemicals, indoor air pollution, and outdoor air pollution. Smoking cessation should be taught to all patients who are currently smoking. Minor respiratory infections that are of no consequence to the person with normal lungs can produce fatal disturbances in the lungs of the person with emphysema. ADLs should be paced throughout the day to permit patients to perform these without excessive distress.

A patient is being admitted to the preoperative holding area for a thoracotomy. Preoperative teaching includes what? A) Correct use of a ventilator B) Correct use of incentive spirometry C) Correct use of a mini-nebulizer D) Correct technique for rhythmic breathing

B) Correct use of incentive spirometry Instruction in the use of incentive spirometry begins before surgery to familiarize the patient with its correct use. You do not teach a patient the use of a ventilator; you explain that he may be on a ventilator to help him breathe. Rhythmic breathing and mini-nebulizers are unnecessary.

The nurse doing rounds at the beginning of a shift notices a sputum specimen in a container sitting on the bedside table in a patients room. The nurse asks the patient when he produced the sputum specimen and he states that the specimen is about 4 hours old. What action should the nurse take? A) Immediately take the sputum specimen to the laboratory. B) Discard the specimen and assist the patient in obtaining another specimen. C) Refrigerate the sputum specimen and submit it once it is chilled. D) Add a small amount of normal saline to moisten the specimen.

B) Discard the specimen and assist the patient in obtaining another specimen. Sputum samples should be submitted to the laboratory as soon as possible. Allowing the specimen to stand for several hours in a warm room results in the overgrowth of contaminated organisms and may make it difficult to identify the pathogenic organisms. Refrigeration of the sputum specimen and the addition of normal saline are not appropriate actions.

An admitting nurse is assessing a patient with COPD. The nurse auscultates diminished breath sounds, which signify changes in the airway. These changes indicate to the nurse to monitor the patient for what? A) Kyphosis and clubbing of the fingers B) Dyspnea and hypoxemia C) Sepsis and pneumothorax D) Bradypnea and pursed lip breathing

B) Dyspnea and hypoxemia These changes in the airway require that the nurse monitor the patient for dyspnea and hypoxemia. Kyphosis is a musculoskeletal problem. Sepsis and pneumothorax are atypical complications. Tachypnea is much more likely than bradypnea. Pursed lip breathing can relieve dyspnea.

The nurse is caring for a patient with chronic obstructive pulmonary disease (COPD). The patient has been receiving high-flow oxygen therapy for an extended time. What symptoms should the nurse anticipate if the patient were experiencing oxygen toxicity? A) Bradycardia and frontal headache B) Dyspnea and substernal pain C) Peripheral cyanosis and restlessness D) Hypotension and tachycardia

B) Dyspnea and substernal pain Oxygen toxicity can occur when patients receive too high a concentration of oxygen for an extended period. Symptoms of oxygen toxicity include dyspnea, substernal pain, restlessness, fatigue, and progressive respiratory difficulty. Bradycardia, frontal headache, cyanosis, hypotension, and tachycardia are not symptoms of oxygen toxicity.

An asthma nurse educator is working with a group of adolescent asthma patients. What intervention is most likely to prevent asthma exacerbations among these patients? A) Encouraging patients to carry a corticosteroid rescue inhaler at all times B) Educating patients about recognizing and avoiding asthma triggers C) Teaching patients to utilize alternative therapies in asthma management D) Ensuring that patients keep their immunizations up to date

B) Educating patients about recognizing and avoiding asthma triggers Asthma exacerbations are best managed by early treatment and education, including the use of written action plans as part of any overall effort to educate patients about self-management techniques, especially those with moderate or severe persistent asthma or with a history of severe exacerbations. Corticosteroids are not used as rescue inhalers. Alternative therapies are not normally a high priority, though their use may be appropriate in some cases. Immunizations should be kept up to date, but this does not necessarily prevent asthma exacerbations.

While assessing a patient who has pneumonia, the nurse has the patient repeat the letter E while the nurses auscultates. The nurse notes that the patients voice sounds are distorted and that the letter A is audible instead of the letter E. How should this finding be documented? A) Bronchophony B) Egophony C) Whispered pectoriloquy D) Sonorous wheezes

B) Egophony This finding would be documented as egophony, which can be best assessed by instructing the patient to repeat the letter E. The distortion produced by consolidation transforms the sound into a clearly heard A rather than E. Bronchophony describes vocal resonance that is more intense and clearer than normal. Whispered pectoriloquy is a very subtle finding that is heard only in the presence of rather dense consolidation of the lungs. Sound is so enhanced by the consolidated tissue that even whispered words are heard. Sonorous wheezes are not defined as a voice sound, but rather as a breath sound.

A sputum study has been ordered for a patient who has developed coarse chest crackles and a fever. At what time should the nurse best collect the sample? A) Immediately after a meal B) First thing in the morning C) At bedtime D) After a period of exercise

B) First thing in the morning Sputum samples ideally are obtained early in the morning before the patient has had anything to eat or drink.

An asthma educator is teaching a patient newly diagnosed with asthma and her family about the use of a peak flow meter. The educator should teach the patient that a peak flow meter measures what value? A) Highest airflow during a forced inspiration B) Highest airflow during a forced expiration C) Airflow during a normal inspiration D) Airflow during a normal expiration

B) Highest airflow during a forced expiration Peak flow meters measure the highest airflow during a forced expiration.

The nurse is caring for a patient who is scheduled to have a thoracotomy. When planning preoperative teaching, what information should the nurse communicate to the patient? A) How to milk the chest tubing B) How to splint the incision when coughing C) How to take prophylactic antibiotics correctly D) How to manage the need for fluid restriction

B) How to splint the incision when coughing Prior to thoracotomy, the nurse educates the patient about how to splint the incision with the hands, a pillow, or a folded towel. The patient is not taught how to milk the chest tubing because this is performed by the nurse. Prophylactic antibiotics are not normally used and fluid restriction is not indicated following thoracotomy.

A patient is brought to the ED by ambulance after a motor vehicle accident in which the patient received blunt trauma to the chest. The patient is in acute respiratory failure, is intubated, and is transferred to the ICU. What parameters of care should the nurse monitor most closely? Select all that apply. A) Coping B) Level of consciousness C) Oral intake D) Arterial blood gases E) Vital signs

B) Level of consciousness D) Arterial blood gases E) Vital signs Patients are usually treated in the ICU. The nurse assesses the patients respiratory status by monitoring the level of responsiveness, ABGs, pulse oximetry, and vital signs. Oral intake and coping are not immediate priorities during the acute stage of treatment, but would become more important later during recovery.

A patient is receiving thrombolytic therapy for the treatment of pulmonary emboli. What is the best way for the nurse to assess the patients oxygenation status at the bedside? A) Obtain serial ABG samples. B) Monitor pulse oximetry readings. C) Test pulmonary function. D) Monitor incentive spirometry volumes.

B) Monitor pulse oximetry readings. The nurse assesses the patient with pulmonary emboli frequently for signs of hypoxemia and monitors the pulse oximetry values to evaluate the effectiveness of the oxygen therapy. ABGs are accurate indicators of oxygenation status, but are not analyzed at the bedside. PFTs and incentive spirometry volumes do not accurately reveal oxygenation status.

A patient has been diagnosed with pulmonary hypertension, in which the capillaries in the alveoli are squeezed excessively. The nurse should recognize a disturbance in what aspect of normal respiratory function? A) Acidbase balance B) Perfusion C) Diffusion D) Ventilation

B) Perfusion Perfusion is influenced by alveolar pressure. The pulmonary capillaries are sandwiched between adjacent alveoli and, if the alveolar pressure is sufficiently high, the capillaries are squeezed. This does not constitute a disturbance in ventilation (air movement), diffusion (gas exchange), or acidbase balance.

A patient with a longstanding diagnosis of generalized anxiety disorder presents to the emergency room. The triage nurse notes upon assessment that the patient is hyperventilating. The triage nurse is aware that hyperventilation is the most common cause of which acidbase imbalance? A) Respiratory acidosis B) Respiratory alkalosis C) Increased PaCO2 D) CNS disturbances

B) Respiratory alkalosis The most common cause of acute respiratory alkalosis is hyperventilation. Extreme anxiety can lead to hyperventilation. Acute respiratory acidosis occurs in emergency situations, such as pulmonary edema, and is exhibited by hypoventilation and decreased PaCO2 . CNS disturbances are found in extreme hyponatremia and fluid overload.

A patient who involved in a workplace accident suffered a penetrating wound of the chest that led to acute respiratory failure. What goal of treatment should the care team prioritize when planning this patients care? A) Facilitation of long-term intubation B) Restoration of adequate gas exchange C) Attainment of effective coping D) Self-management of oxygen therapy

B) Restoration of adequate gas exchange The objectives of treatment are to correct the underlying cause of respiratory failure and to restore adequate gas exchange in the lung. This is priority over coping and self-care. Long-term ventilation may or may not be indicated.

The nurse is caring for a patient 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? A) Sputum production B) Shortness of breath C) Throat discomfort D) Epistaxis

B) Shortness of breath Follow-up care in the health care facility and at home involves monitoring the patient 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.

An older adult patient has been diagnosed with COPD. What characteristic of the patients current health status would preclude the safe and effective use of a metered-dose inhaler (MDI)? A) The patient has not yet quit smoking. B) The patient has severe arthritis in her hands. C) The patient requires both corticosteroids and beta2 -agonists. D) The patient has cataracts.

B) The patient has severe arthritis in her hands. Safe and effective MDI use requires the patient to be able to manipulate the device independently, which may be difficult if the patient has arthritis. Smoking does not preclude MDI use. A modest loss of vision does not preclude the use of an MDI and a patient can safely use more than one MDI.

A nurses assessment reveals that a client with COPD may be experiencing bronchospasm. What assessment finding would suggest that the patient is experiencing bronchospasm? A) Fine or coarse crackles on auscultation B) Wheezes or diminished breath sounds on auscultation C) Reduced respiratory rate or lethargy D) Slow, deliberate respirations

B) Wheezes or diminished breath sounds on auscultation Wheezing and diminished breath sounds are consistent with bronchospasm. Crackles are usually attributable to other respiratory or cardiac pathologies. Bronchospasm usually results in rapid, inefficient breathing and agitation.

While caring for a patient with an endotracheal tube, the nurses recognizes that suctioning is required how often? A) Every 2 hours when the patient is awake B) When adventitious breath sounds are auscultated C) When there is a need to prevent the patient from coughing D) When the nurse needs to stimulate the cough reflex

B) When adventitious breath sounds are auscultated It is usually necessary to suction the patients secretions because of the decreased effectiveness of the cough mechanism. Tracheal suctioning is performed when adventitious breath sounds are detected or whenever secretions are present. Unnecessary suctioning, such as scheduling every 2 hours, can initiate bronchospasm and cause trauma to the tracheal mucosa.

The nurse is assessing a patient whose respiratory disease in characterized by chronic hyperinflation of the lungs. What would the nurse most likely assess in this patient? A) Signs of oxygen toxicity B) Chronic chest pain C) A barrel chest D) Long, thin fingers

C) A barrel chest In COPD patients with a primary emphysematous component, chronic hyperinflation leads to the barrel chest thorax configuration. The nurse most likely would not assess chest pain or long, thin fingers; these are not characteristic of emphysema. The patient would not show signs of oxygen toxicity unless he or she received excess supplementary oxygen.

A school nurse is caring for a 10-year-old girl who is having an asthma attack. What is the preferred intervention to alleviate this clients airflow obstruction? A) Administer corticosteroids by metered dose inhaler B) Administer inhaled anticholinergics C) Administer an inhaled beta-adrenergic agonist D) Utilize a peak flow monitoring device

C) Administer an inhaled beta-adrenergic agonist Asthma exacerbations are best managed by early treatment and education of the patient. Quick-acting beta-adrenergic medications are the first used for prompt relief of airflow obstruction. Systemic corticosteroids may be necessary to decrease airway inflammation in patients who fail to respond to inhaled beta-adrenergic medication. A peak flow device will not resolve short-term shortness of breath.

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

C) An arterial blood gas (ABG) study The arterial oxygen tension (partial pressure or PaO2) indicates the degree of oxygenation of the blood, and the arterial carbon dioxide tension (partial pressure or PaCO2) indicates the adequacy of alveolar ventilation. 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. Capillary blood samples are venous blood, not arterial blood, so they are not as accurate as an ABG. Pulse oximetry is a useful clinical tool but does not replace ABG measurement, because it is not as accurate. A CBC does not indicate the concentration of oxygen.

The nurse is providing discharge teaching for a patient who developed a pulmonary embolism after total knee surgery. The patient has been converted from heparin to sodium warfarin (Coumadin) anticoagulant therapy. What should the nurse teach the client? A) Coumadin will continue to break up the clot over a period of weeks B) Coumadin must be taken concurrent with ASA to achieve anticoagulation. C) Anticoagulant therapy usually lasts between 3 and 6 months. D) He should take a vitamin supplement containing vitamin K

C) Anticoagulant therapy usually lasts between 3 and 6 months. Anticoagulant therapy prevents further clot formation, but cannot be used to dissolve a clot. The therapy continues for approximately 3 to 6 months and is not combined with ASA. Vitamin K reverses the effect of anticoagulant therapy and normally should not be taken.

The nurse is preparing to suction a patient with an endotracheal tube. What should be the nurses first step in the suctioning process? A) Explain the suctioning procedure to the patient and reposition the patient. B) Turn on suction source at a pressure not exceeding 120 mm Hg. C) Assess the patients lung sounds and SAO2 via pulse oximeter. D) Perform hand hygiene and don nonsterile gloves, goggles, gown, and mask.

C) Assess the patients lung sounds and SAO2 via pulse oximeter. Assessment data indicate the need for suctioning and allow the nurse to monitor the effect of suction on the patients level of oxygenation. Explaining the procedure would be the second step; performing hand hygiene is the third step, and turning on the suction source is the fourth step.

The nurse is caring for a patient who is receiving oxygen therapy for pneumonia. How should the nurse best assess whether the patient is hypoxemic? A) Assess the patients level of consciousness (LOC). B) Assess the patients extremities for signs of cyanosis. C) Assess the patients oxygen saturation level. D) Review the patients hemoglobin, hematocrit, and red blood cell levels.

C) Assess the patients oxygen saturation level. The effectiveness of the patients oxygen therapy is assessed by the ABG analysis or pulse oximetry. ABG results may not be readily available. Presence or absence of cyanosis is not an accurate indicator of oxygen effectiveness. The patients LOC may be affected by hypoxia, but not every change in LOC is related to oxygenation. Hemoglobin, hematocrit, and red blood cell levels do not directly reflect current oxygenation status.

The ED nurse is assessing the respiratory function of a teenage girl who presented with acute shortness of breath. Auscultation reveals continuous wheezes during inspiration and expiration. This finding is most suggestive what? A) Pleurisy B) Emphysema C) Asthma D) Pneumonia

C) Asthma Sibilant wheezes are commonly associated with asthma. They do not normally accompany pleurisy, emphysema, or pneumonia.

A nurse is completing a focused respiratory assessment of a child with asthma. What assessment finding is most closely associated with the characteristic signs and symptoms of asthma? A) Shallow respirations B) Increased anterior-posterior (A-P) diameter C) Bilateral wheezes D) Bradypnea

C) Bilateral wheezes The three most common symptoms of asthma are cough, dyspnea, and wheezing. There may be generalized wheezing (the sound of airflow through narrowed airways), first on expiration and then, possibly, during inspiration as well. Respirations are not usually slow and the childs A-P diameter does not normally change.

A student nurse is preparing to care for a patient with bronchiectasis. The student nurse should recognize that this patient is likely to experience respiratory difficulties related to what pathophysiologic process? A) Intermittent episodes of acute bronchospasm B) Alveolar distention and impaired diffusion C) Dilation of bronchi and bronchioles D) Excessive gas exchange in the bronchioles

C) Dilation of bronchi and bronchioles Bronchiectasis is a chronic, irreversible dilation of the bronchi and bronchioles that results from destruction of muscles and elastic connective tissue. It is not characterized by acute bronchospasm,

The nurse is completing a patients health history with regard to potential risk factors for lung disease. What interview question addresses the most significant risk factor for respiratory diseases? A) Have you ever been employed in a factory, smelter, or mill? B) Does anyone in your family have any form of lung disease? C) Do you currently smoke, or have you ever smoked? D) Have you ever lived in an area that has high levels of air pollution?

C) Do you currently smoke, or have you ever smoked? Smoking the single most important contributor to lung disease, exceeds the significance of environmental, occupational, and genetic factors.

The nurse is assessing the respiratory status of a patient who is experiencing an exacerbation of her emphysema symptoms. When preparing to auscultate, what breath sounds should the nurse anticipate? A) Absence of breath sounds B) Wheezing with discontinuous breath sounds C) Faint breath sounds with prolonged expiration D) Faint breath sounds with fine crackles

C) Faint breath sounds with prolonged expiration The breath sounds of the patient with emphysema are faint or often completely inaudible. When they are heard, the expiratory phase is prolonged.

A patients severe asthma has necessitated the use of a long-acting beta2 -agonist (LABA). Which of the patients statements suggests a need for further education? A) I know that these drugs can sometimes make my heart beat faster. B) Ive heard that this drug is particularly good at preventing asthma attacks during exercise. C) Ill make sure to use this each time I feel an asthma attack coming on. D) Ive heard that this drug sometimes gets less effective over time.

C) Ill make sure to use this each time I feel an asthma attack coming on. LABAs are not used for management of acute asthma symptoms. Tachycardia is a potential adverse effect and decreased protection against exercise-induced bronchospasm may occur with regular use.

A medical nurse has admitted a patient to the unit with a diagnosis of failure to thrive. The patient has developed a fever and cough, so a sputum specimen has been obtained. The nurse notes that the sputum is greenish and that there is a large quantity of it. The nurse notifies the patients physician because these symptoms are suggestive of what? A) Pneumothorax B) Lung tumors C) Infection D) Pulmonary edema

C) Infection The nature of the sputum is often indicative of its cause. A profuse amount of purulent sputum (thick and yellow, green, or rust-colored) or a change in color of the sputum is a common sign of a bacterial infection. Pink-tinged mucoid sputum suggests a lung tumor. Profuse, frothy, pink material, often welling up into the throat, may indicate pulmonary edema. A pneumothorax does not result in copious,

A patient is undergoing testing to see if he has a pleural effusion. Which of the nurses respiratory assessment findings would be most consistent with this diagnosis? A) Increased tactile fremitus, egophony, and a dull sound upon percussion of the chest wall B) Decreased tactile fremitus, wheezing, and a hyperresonant sound upon percussion of the chest wall C) Lung fields dull to percussion, absent breath sounds, and a pleural friction rub D) Normal tactile fremitus, decreased breath sounds, and a resonant sound upon percussion of the chest wall

C) Lung fields dull to percussion, absent breath sounds, and a pleural friction rub Assessment findings consistent with a pleural effusion include affected lung fields being dull to percussion and absence of breath sounds. A pleural friction rub may also be present. The other listed signs are not typically associated with a pleural effusion.

A nurse has performed tracheal suctioning on a patient who experienced increasing dyspnea prior to a procedure. When applying the nursing process, how can the nurse best evaluate the outcomes of this intervention? A) Determine whether the patient can now perform forced expiratory technique (FET). B) Percuss the patients lungs and thorax. C) Measure the patients oxygen saturation. D) Have the patient perform incentive spirometry.

C) Measure the patients oxygen saturation. The patients response to suctioning is usually determined by performing chest auscultation and by measuring the patients oxygen saturation. FET, incentive spirometry, and percussion are not normally used as evaluative techniques.

The critical care nurse is precepting a new nurse on the unit. Together they are caring for a patient who has a tracheostomy tube and is receiving mechanical ventilation. What action should the critical care nurse recommend when caring for the cuff? A) Deflate the cuff overnight to prevent tracheal tissue trauma. B) Inflate the cuff to the highest possible pressure in order to prevent aspiration. C) Monitor the pressure in the cuff at least every 8 hours D) Keep the tracheostomy tube plugged at all times.

C) Monitor the pressure in the cuff at least every 8 hours Cuff pressure must be monitored by the respiratory therapist or nurse at least every 8 hours by attaching a handheld pressure gauge to the pilot balloon of the tube or by using the minimal leak volume or minimal occlusion volume technique. Plugging is only used when weaning the patient from tracheal support. Deflating the cuff overnight would be unsafe and inappropriate. High cuff pressure can cause tissue trauma.

A gerontologic nurse is teaching a group of medical nurses about the high incidence and mortality of pneumonia in older adults. What is a contributing factor to this that the nurse should describe? A) Older adults have less compliant lung tissue than younger adults. B) Older adults are not normally candidates for pneumococcal vaccination. C) Older adults often lack the classic signs and symptoms of pneumonia. D) Older adults often cannot tolerate the most common antibiotics used to treat pneumonia.

C) Older adults often lack the classic signs and symptoms of pneumonia. The diagnosis of pneumonia may be missed because the classic symptoms of cough, chest pain, sputum production, and fever may be absent or masked in older adult patients. Mortality from pneumonia in the elderly is not a result of limited antibiotic options or lower lung compliance. The pneumococcal vaccine is appropriate for older adults.

The nurse is reviewing the electronic health record of a patient with an empyema. What health problem in the patients history is most likely to have caused the empyema? A) Smoking B) Asbestosis C) Pneumonia D) Lung cancer

C) Pneumonia Most empyemas occur as complications of bacterial pneumonia or lung abscess. Cancer, smoking, and asbestosis are not noted to be common causes.

A patient arrives in the emergency department with an attack of acute bronchiectasis. Chest auscultation reveals the presence of copious secretions. What intervention should the nurse prioritize in this patients care? A) Oral administration of diuretics B) Intravenous fluids to reduce the viscosity of secretions C) Postural chest drainage D) Pulmonary function testing

C) Postural chest drainage Postural drainage is part of all treatment plans for bronchiectasis, because draining of the bronchiectatic areas by gravity reduces the amount of secretions and the degree of infection. Diuretics and IV fluids will not aid in the mobilization of secretions. Lung function testing may be indicated, but this assessment will not relieve the patients symptoms.

A nurse is creating a health promotion intervention focused on chronic obstructive pulmonary disease (COPD). What should the nurse identify as a complication of COPD? A) Lung cancer B) Cystic fibrosis C) Respiratory failure D) Hemothorax

C) Respiratory failure Complications of COPD include respiratory failure, pneumothorax, atelectasis, pneumonia, and pulmonary hypertension (corpulmonale). Lung cancer, cystic fibrosis, and hemothorax are not common complications.

A student nurse is developing a teaching plan for an adult patient with asthma. Which teaching point should have the highest priority in the plan of care that the student is developing? A) Gradually increase levels of physical exertion. B) Change filters on heaters and air conditioners frequently. C) Take prescribed medications as scheduled. D) Avoid goose-down pillows.

C) Take prescribed medications as scheduled. Although all of the measures are appropriate for a client with asthma, taking prescribed medications on time is the most important measure in preventing asthma attacks.

The home care nurse is assessing a patient who requires home oxygen therapy. What criterion indicates that an oxygen concentrator will best meet the needs of the patient in the home environment? A) The patient desires a low-maintenance oxygen delivery system that delivers oxygen flow rates up to 6 L/min. B) The patient requires a high-flow system for use with a tracheostomy collar. C) The patient desires a portable oxygen delivery system that can deliver 2 L/min. D) The patients respiratory status requires a system that provides an FiO2 of 65%.

C) The patient desires a portable oxygen delivery system that can deliver 2 L/min. The use of oxygen concentrators is another means of providing varying amounts of oxygen, especially in the home setting. They can deliver oxygen flows from 1 to 10 L/min and provide an FiO2 of about 40%. They require regular maintenance and are not used for high-flow applications. The patient desiring a portable oxygen delivery system of 2L/min will benefit from the use of an oxygen concentrator.

A nurse is providing discharge teaching for a client with COPD. When teaching the client about breathing exercises, what should the nurse include in the teaching? A) Lie supine to facilitate air entry B) Avoid pursed lip breathing C) Use diaphragmatic breathing D) Use chest breathing

C) Use diaphragmatic breathing Inspiratory muscle training and breathing retraining may help improve breathing patterns in patients with COPD. Training in diaphragmatic breathing reduces the respiratory rate, increases alveolar ventilation, and, sometimes, helps expel as much air as possible during expiration. Pursed-lip breathing helps slow expiration, prevents collapse of small airways, and controls the rate and depth of respiration. Diaphragmatic breathing, not chest breathing, increases lung expansion. Supine positioning does not aid breathing.

A patient with a severe exacerbation of COPD requires reliable and precise oxygen delivery. Which mask will the nurse expect the physician to order? A) Non-rebreather air mask B) Tracheostomy collar C) Venturi mask D) Face tent

C) Venturi mask The Venturi mask provides the most accurate method of oxygen delivery. Other methods of oxygen delivery include the aerosol mask, tracheostomy collar, and face tents, but these do not match the precision of a Venturi mask.

The nurse is performing nasotracheal suctioning on a medical patient and obtains copious amounts of secretions from the patients airway, even after inserting and withdrawing the catheter several times. How should the nurse proceed? A) Continue suctioning the patient until no more secretions are obtained. B) Perform chest physiotherapy rather than nasotracheal suctioning. C) Wait several minutes and then repeat suctioning. D) Perform postural drainage and then repeat suctioning.

C) Wait several minutes and then repeat suctioning. If additional suctioning is needed, the nurse should withdraw the catheter to the back of the pharynx, reassure the patient, and oxygenate for several minutes before resuming suctioning. Chest physiotherapy and postural drainage are not necessarily indicated.

A patient is being treated for a pulmonary embolism and the medical nurse is aware that the patient suffered an acute disturbance in pulmonary perfusion. This involved an alteration in what aspect of normal physiology? A) Maintenance of constant osmotic pressure in the alveoli B) Maintenance of muscle tone in the diaphragm C) pH balance in the pulmonary veins and arteries D) Adequate flow of blood through the pulmonary circulation.

D) Adequate flow of blood through the pulmonary circulation. Pulmonary perfusion is the actual blood flow through the pulmonary circulation. Perfusion is not defined in terms of pH balance, muscle tone, or osmotic pressure.

A patients plan of care specifies postural drainage. What action should the nurse perform when providing this noninvasive therapy? A) Administer the treatment with the patient in a high Fowlers or semi-Fowlers position. B) Perform the procedure immediately following the patients meals. C) Apply percussion firmly to bare skin to facilitate drainage. D) Assist the patient into a position that will allow gravity to move secretions.

D) Assist the patient into a position that will allow gravity to move secretions. Postural drainage is usually performed two to four times per day. The patient uses gravity to facilitate postural draining. The skin should be covered with a cloth or a towel during percussion to protect the skin. Postural drainage is not administered in an upright position or directly following a meal.

A nurse is teaching a patient how to perform flow type incentive spirometry prior to his scheduled thoracic surgery. What instruction should the nurse provide to the patient? A) Hold the spirometer at your lips and breathe in and out like you normally would. B) When youre ready, blow hard into the spirometer for as long as you can. C) Take a deep breath and then blow short, forceful breaths into the spirometer. D) Breathe in deeply through the spirometer, hold your breath briefly, and then exhale.

D) Breathe in deeply through the spirometer, hold your breath briefly, and then exhale. The patient should be taught to lace the mouthpiece of the spirometer firmly in the mouth, breathe air in through the mouth, and hold the breath at the end of inspiration for about 3 seconds. The patient should then exhale slowly through the mouthpiece.

The home care nurse is planning to begin breathing retraining exercises with a client newly admitted to the home health service. The home care nurse knows that breathing retraining is especially indicated if the patient has what diagnosis? A) Asthma B) Pneumonia C) Lung cancer D) COPD

D) COPD Breathing retraining is especially indicated in patients with COPD and dyspnea. Breathing retraining may be indicated in patients with other lung pathologies, but not to the extent indicated in patients with COPD.

A nurse is documenting the results of assessment of a patient with bronchiectasis. What would the nurse most likely include in documentation? A) Sudden onset of pleuritic chest pain B) Wheezes on auscultation C) Increased anterior-posterior (A-P) diameter D) Clubbing of the fingers

D) Clubbing of the fingers Characteristic symptoms of bronchiectasis include chronic cough and production of purulent sputum in copious amounts. Clubbing of the fingers also is common because of respiratory insufficiency. Sudden pleuritic chest pain is a common manifestation of a pulmonary embolism. Wheezes on auscultation are common in patients with asthma. An increased A-P diameter is noted in patients with COPD.

A patient has been diagnosed with heart failure that has not yet responded to treatment. What breath sound should the nurse expect to assess on auscultation? A) Expiratory wheezes B) Inspiratory wheezes C) Rhonchi D) Crackles

D) Crackles Crackles reflect underlying inflammation or congestion and are often present in such conditions as pneumonia, bronchitis, and congestive heart failure. Rhonchi and wheezes are associated with airway obstruction, which is not a part of the pathophysiology of heart failure.

The nurse is assessing a patient 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 patients respirations. How should the nurse best respond to this assessment finding? A) Gently reinsert the chest tube 1 to 2 cm and observe if the water level stabilizes. B) Inform the physician promptly that there is in imminent leak in the drainage system. C) Encourage the patient to do deep breathing and coughing exercises. D) Document that the chest drainage system is operating as it is intended.

D) Document that the chest drainage system is operating as it is intended. Fluctuation of the water level in the water seal shows effective connection between the pleural cavity and the drainage chamber and indicates that the drainage system remains patent. No further action is needed.

A nurse is caring for a patient with COPD. The patients medication regimen has been recently changed and the nurse is assessing for therapeutic effect of a new bronchodilator. What assessment parameters suggest a consequent improvement in respiratory status? Select all that apply. A) Negative sputum culture B) Increased viscosity of lung secretions C) Increased respiratory rate D) Increased expiratory flow rate E) Relief of dyspnea

D) Increased expiratory flow rate E) Relief of dyspnea The relief of bronchospasm is confirmed by measuring improvement in expiratory flow rates and volumes (the force of expiration, how long it takes to exhale, and the amount of air exhaled) as well as by assessing the dyspnea and making sure that it has lessened. Increased respiratory rate and viscosity of secretions would suggest a worsening of the patients respiratory status. Bronchodilators would not have a direct result on the patients infectious process.

A patient is scheduled to have excess pleural fluid aspirated with a needle in order to relieve her dyspnea. The patient inquires about the normal function of pleural fluid. What should the nurse describe? A) It allows for full expansion of the lungs within the thoracic cavity. B) It prevents the lungs from collapsing within the thoracic cavity. C) It limits lung expansion within the thoracic cavity. D) It lubricates the movement of the thorax and lungs.

D) It lubricates the movement of the thorax and lungs. The visceral pleura cover the lungs; the parietal pleura line the thorax. The visceral and parietal pleura and the small amount of pleural fluid between these two membranes serve to lubricate the thorax and lungs and permit smooth motion of the lungs within the thoracic cavity with each breath. The pleura do not allow full expansion of the lungs, prevent the lungs from collapsing, or limit lung expansion within the thoracic cavity.

The medical nurse is creating the care plan of an adult patient requiring mechanical ventilation. What nursing action is most appropriate? A) Keep the patient in a low Fowlers position. B) Perform tracheostomy care at least once per day. C) Maintain continuous bedrest. D) Monitor cuff pressure every 8 hours.

D) Monitor cuff pressure every 8 hours. The cuff pressure should be monitored every 8 hours. It is important to perform tracheostomy care at least every 8 hours because of the risk of infection. The patient should be encouraged to ambulate, if possible, and a low Fowlers position is not indicated.

The nurse is explaining the safe and effective administration of nasal spray to a patient with seasonal allergies. What information is most important to include in this teaching? A) Finish the bottle of nasal spray to clear the infection effectively. B) Nasal spray can only be shared between immediate family members. C) Nasal spray should be administered in a prone position. D) Overuse of nasal spray may cause rebound congestion.

D) Overuse of nasal spray may cause rebound congestion. The use of topical decongestants is controversial because of the potential for a rebound effect. The patient should hold his or her head back for maximal distribution of the spray. Only the patient should use the bottle.

A patient in the ICU is status post embolectomy after a pulmonary embolus. What assessment parameter does the nurse monitor most closely on a patient who is postoperative following an embolectomy? A) Pupillary response B) Pressure in the vena cava C) White blood cell differential D) Pulmonary arterial pressure

D) Pulmonary arterial pressure If the patient has undergone surgical embolectomy, the nurse measures the patients pulmonary arterial pressure and urinary output. Pressure is not monitored in a patients vena cava. White cell levels and pupillary responses would be monitored, but not to the extent of the patients pulmonary arterial pressure.

In addition to heart rate, blood pressure, respiratory rate, and temperature, the nurse needs to assess a patients arterial oxygen saturation (SaO2). What procedure will best accomplish this? A) Incentive spirometry B) Arterial blood gas (ABG) measurement C) Peak flow measurement D) Pulse oximetry

D) Pulse oximetry Pulse oximetry is a noninvasive procedure in which a small sensor is positioned over a pulsating vascular bed. It can be used during transport and causes the patient no discomfort. An incentive spirometer is used to assist the patient with deep breathing after surgery. ABG measurement can measure SaO2, but this is an invasive procedure that can be painful. Some patients with asthma use peak flow meters to measure levels of expired air.

The home care nurse is monitoring a patient discharged home after resolution of a pulmonary embolus. For what potential complication would the home care nurse be most closely monitoring this patient? A) Signs and symptoms of pulmonary infection B) Swallowing ability and signs of aspiration C) Activity level and role performance D) Residual effects of compromised oxygenation

D) Residual effects of compromised oxygenation The home care nurse should monitor the patient for residual effects of the PE, which involved a severe disruption in respiration and oxygenation. PE has a noninfectious etiology; pneumonia is not impossible, but it is a less likely sequela. Swallowing ability is unlikely to be affected; activity level is important, but secondary to the effects of deoxygenation.

The decision has been made to discharge a ventilator-dependent patient home. The nurse is developing a teaching plan for this patient and his family. What would be most important to include in this teaching plan? A) Administration of inhaled corticosteroids B) Assessment of neurologic status C) Turning and coughing D) Signs of pulmonary infection

D) Signs of pulmonary infection The nurse teaches the patient and family about the ventilator, suctioning, tracheostomy care, signs of pulmonary infection, cuff inflation and deflation, and assessment of vital signs. Neurologic assessment and turning and coughing are less important than signs and symptoms of infection. Inhaled corticosteroids may or may not be prescribed.

The nurse caring for a patient recently diagnosed with lung disease encourages the patient not to smoke. What is the primary rationale behind this nursing action? A) Smoking decreases the amount of mucus production. B) Smoke particles compete for binding sites on hemoglobin. C) Smoking causes atrophy of the alveoli. D) Smoking damages the ciliary cleansing mechanism.

D) Smoking damages the ciliary cleansing mechanism. In addition to irritating the mucous cells of the bronchi and inhibiting the function of alveolar macrophage (scavenger) cells, smoking damages the ciliary cleansing mechanism of the respiratory tract. Smoking also increases the amount of mucus production and distends the alveoli in the lungs. It reduces the oxygen-carrying capacity of hemoglobin, but not by directly competing for binding sites.

A nurse is providing health education to the family of a patient with bronchiectasis. What should the nurse teach the patients family members? A) The correct technique for chest palpation and auscultation B) Techniques for assessing the patients fluid balance C) The technique for providing deep nasotracheal suctioning D) The correct technique for providing postural drainage

D) The correct technique for providing postural drainage A focus of the care of bronchiectasis is helping patients clear pulmonary secretions; consequently, patients and families are taught to perform postural drainage. Chest palpation and auscultation and assessment of fluid balance are not prioritized over postural drainage. Nasotracheal suctioning is not normally necessary.

The nurse caring for a patient with an endotracheal tube recognizes several disadvantages of an endotracheal tube. What would the nurse recognize as a disadvantage of endotracheal tubes? A) Cognition is decreased. B) Daily arterial blood gases (ABGs) are necessary. C) Slight tracheal bleeding is anticipated. D) The cough reflex is depressed.

D) The cough reflex is depressed. There are several disadvantages of an endotracheal tube. Disadvantages include suppression of the patients cough reflex, thickening of secretions, and depressed swallowing reflexes. Ulceration and stricture of the larynx or trachea may develop, but bleeding is not an expected finding. The tube should not influence cognition and daily ABGs are not always required.

A clinic nurse is caring for a patient who has just been diagnosed with chronic obstructive pulmonary disease (COPD). The patient asks the nurse what he could have done to minimize the risk of contracting this disease. What would be the nurses best answer? A) The most important risk factor for COPD is exposure to occupational toxins. B) The most important risk factor for COPD is inadequate exercise. C) The most important risk factor for COPD is exposure to dust and pollen. D) The most important risk factor for COPD is cigarette smoking.

D) The most important risk factor for COPD is cigarette smoking. The most important risk factor for COPD is cigarette smoking. Lack of exercise and exposure to dust and pollen are not risk factors for COPD. Occupational risks are significant but are far exceeded by smoking.

A nurse is explaining to a patient with asthma what her new prescription for prednisone is used for. What would be the most accurate explanation that the nurse could give? A) To ensure long-term prevention of asthma exacerbations B) To cure any systemic infection underlying asthma attacks C) To prevent recurrent pulmonary infections D) To gain prompt control of inadequately controlled, persistent asthma

D) To gain prompt control of inadequately controlled, persistent asthma Prednisone is used for a short-term (310 days) burst to gain prompt control of inadequately controlled, persistent asthma. It is not used to treat infection or to prevent exacerbations in the long term.

The nurse is caring for a patient who has been scheduled for a bronchoscopy. How should the nurse prepare the patient for this procedure? A) Administer a bolus of IV fluids. B) Arrange for the insertion of a peripherally inserted central catheter. C) Administer nebulized bronchodilators every 2 hours until the test. D) Withhold food and fluids for several hours before the test.

D) Withhold food and fluids for several hours before the test. Food and fluids are withheld for 4 to 8 hours before the test to reduce the risk of aspiration when the cough reflex is blocked by anesthesia. IV fluids, bronchodilators, and a central line are unnecessary.
