A female client with asthma is receiving a theophylline preparation to promote bronchodilation. Because of the risk of drug toxicity, the nurse must monitor the client's serum theophylline level closely. The nurse knows that the therapeutic theophylline concentration falls within which range? a. 1 to 2 mcg/ml b. 2 to 5 mcg/ml c. 5 to 10 mcg/ml d. 10 to 20 mcg/ml
Answer D. The therapeutic serum theophylline concentration ranges from 10 to 20 mcg/ml. Values below 10 mcg/ml aren't therapeutic.
A nurse is suctioning fluids from a male client via a tracheostomy tube. When suctioning, the nurse must limit the suctioning time to a maximum of: a. 1 minute b. 5 seconds c. 10 seconds d. 30 seconds
Answer C. Hypoxemia can be caused by prolonged suctioning, which stimulates the pacemaker cells in the heart. A vasovagal response may occur, causing bradycardia. The nurse must preoxygenate the client before suctioning and limit the suctioning pass to 10 seconds.
For a male client with an endotracheal (ET) tube, which nursing action is most essential? a. Auscultating the lungs for bilateral breath sounds b. Turning the client from side to side every 2 hours c. Monitoring serial blood gas values every 4 hours d. Providing frequent oral hygiene
Answer A. For a client with an ET tube, the most important nursing action is auscultating the lungs regularly for bilateral breath sounds to ensure proper tube placement and effective oxygen delivery. Although the other options are appropriate for this client, they're secondary to ensuring adequate oxygenation.
The amount of air inspired and expired with each breath is called: a. tidal volume. b. residual volume. c. vital capacity. d. dead-space volume.
Answer A. Tidal volume is the amount of air inspired and expired with each breath. Residual volume is the amount of air remaining in the lungs after forcibly exhaling. Vital capacity is the maximum amount of air that can be moved out of the lungs after maximal inspiration and expiration. Dead-space volume is the amount of air remaining in the upper airways that never reaches the alveoli. In pathologic conditions, dead space may also exist in the lower airways.
The nurse assesses a male client's respiratory status. Which observation indicates that the client is experiencing difficulty breathing? a. Diaphragmatic breathing b. Use of accessory muscles c. Pursed-lip breathing d. Controlled breathing
Answer B. The use of accessory muscles for respiration indicates the client is having difficulty breathing. Diaphragmatic and pursed-lip breathing are two controlled breathing techniques that help the client conserve energy.
Gina, a home health nurse is visiting a home care client with advanced lung cancer. Upon assessing the client, the nurse discovers wheezing, bradycardia, and a respiratory rate of 10 breaths/minute. These signs are associated with which condition? a. Hypoxia b. Delirium c. Hyperventilation d. Semiconsciousness
Answer A. As the respiratory center in the brain becomes depressed, hypoxia occurs, producing wheezing, bradycardia, and a decreased respiratory rate. Delirium is a state of mental confusion characterized by disorientation to time and place. Hyperventilation (respiratory rate greater than that metabolically necessary for gas exchange) is marked by an increased respiratory rate or tidal volume, or both. Semiconsciousness is a state of impaired consciousness characterized by limited motor and verbal responses and decreased orientation.
A nurse is assessing a male client with chronic airflow limitations and notes that the client has a "barrel chest." The nurse interprets that this client has which of the following forms of chronic airflow limitations? a. Emphysema b. Bronchial asthma c. Chronic obstructive bronchitis d. Bronchial asthma and bronchitis
Answer A. The client with emphysema has hyperinflation of the alveoli and flattening of the diaphragm. These lead to increased anteroposterior diameter, referred to as "barrel chest." The client also has dyspnea with prolonged expiration and has hyperresonant lungs to percussion.
What is the normal pH range for arterial blood? a. 7 to 7.49 b. 7.35 to 7.45 c. 7.50 to 7.60 d. 7.55 to 7.65
Answer B. A pH less than 7.35 is indicative of acidosis; a pH above 7.45 indicates alkalosis.
The nurse is caring for a male client with a chest tube. If the chest drainage system is accidentally disconnected, what should the nurse plan to do? a. Place the end of the chest tube in a container of sterile saline. b. Apply an occlusive dressing and notify the physician. c. Clamp the chest tube immediately. d. Secure the chest tube with tape.
qAnswer A. If a chest drainage system is disconnected, the nurse may place the end of the chest tube in a container of sterile saline or water to prevent air from entering the chest tube, thereby preventing negative respiratory pressure. The nurse should apply an occlusive dressing if the chest tube is pulled out — not if the system is disconnected. The nurse shouldn't clamp the chest tube because clamping increases the risk of tension pneumothorax. The nurse should tape the chest tube securely to prevent it from being disconnected, rather than taping it after it has been disconnected.
A nurse is taking pulmonary artery catheter measurements of a male client with acute respiratory distress syndrome. The pulmonary capillary wedge pressure reading is 12mm Hg. The nurse interprets that this readings is: a. High and expected b. Low and unexpected c. Normal and expected d. Uncertain and unexpected
Answer C. The normal pulmonary capillary wedge pressure (PCWP) is 8 to 13 mm Hg, and the client is considered to have high readings if they exceed 18 to 20 mm Hg. The client with acute respiratory distress syndrome has a normal PCWP, which is an expected finding because the edema is in the interstitium of the lung and is noncardiac.
Nurse Paul is assisting a physician with the removal of a chest tube. The nurse should instruct the client to: a. Exhale slowly. b. Stay very still. c. Inhale and exhale quickly. d. Perform the Valsalva maneuver.
Answer D. When the chest tube is removed, the client is asked to perform the Valsalva maneuver (take a deep breath, exhale, and bear down). The tube is quickly withdrawn, and an airtight dressing is taped in place. An alternative instruction is to ask the client to take a deep breath and hold the breath while the tube is removed. Options A, B, and C are incorrect client instructions.
Nurse Kim is caring for a client with a pneumothorax and who has had a chest tube inserted notes continuous gentle bubbling in the suction control chamber. What action is appropriate? a. Do nothing, because this is an expected finding. b. Immediately clamp the chest tube and notify the physician. c. Check for an air leak because the bubbling should be intermittent. d. Increase the suction pressure so that bubbling becomes vigorous.
Answer A. Continuous gentle bubbling should be noted in the suction control chamber. Option B is incorrect. Chest tubes should only be clamped to check for an air leak or when changing drainage devices (according to agency policy). Option C is incorrect. Bubbling should be continuous and not intermittent. Option D is incorrect because bubbling should be gentle. Increasing the suction pressure only increases the rate of evaporation of water in the drainage system.
Nurse Julia is caring for a client who has a tracheostomy and temperature of 103° F (39.4° C). Which of the following interventions will most likely lower the client's arterial blood oxygen saturation? a. Endotracheal suctioning b. Encouragement of coughing c. Use of cooling blanket d. Incentive spirometry
Answer A. Endotracheal suctioning removes secretions as well as gases from the airway and lowers the arterial oxygen saturation (SaO2) level. Coughing and incentive spirometry improves oxygenation and should raise or maintain oxygen saturation. Because of superficial vasoconstriction, using a cooling blanket can lower peripheral oxygen saturation readings, but SaO2 levels wouldn't be affected.
On arrival at the intensive care unit, a critically ill female client suffers respiratory arrest and is placed on mechanical ventilation. The physician orders pulse oximetry to monitor the client's arterial oxygen saturation (SaO2) noninvasively. Which vital sign abnormality may alter pulse oximetry values? a. Fever b. Tachypnea c. Tachycardia d. Hypotension
Answer D. Hypotension, hypothermia, and vasoconstriction may alter pulse oximetry values by reducing arterial blood flow. Likewise, movement of the finger to which the oximeter is applied may interfere with interpretation of SaO2. All of these conditions limit the usefulness of pulse oximetry. Fever, tachypnea, and tachycardia don't affect pulse oximetry values directly.
A male client with Guillain-Barré syndrome develops respiratory acidosis as a result of reduced alveolar ventilation. Which combination of arterial blood gas (ABG) values confirms respiratory acidosis? a. pH, 5.0; PaCO2 30 mm Hg b. pH, 7.40; PaCO2 35 mm Hg c. pH, 7.35; PaCO2 40 mm Hg d. pH, 7.25; PaCO2 50 mm Hg
Answer D. In respiratory acidosis, ABG analysis reveals an arterial pH below 7.35 and partial pressure of arterial carbon dioxide (PaCO2) above 45 mm Hg. Therefore, the combination of a pH value of 7.25 and a PaCO2 value of 50 mm Hg confirms respiratory acidosis. A pH value of 5.0 with a PaCO2 value of 30 mm Hg indicates respiratory alkalosis. Options B and C represent normal ABG values, reflecting normal gas exchange in the lungs.
A male client admitted to an acute care facility with pneumonia is receiving supplemental oxygen, 2 L/minute via nasal cannula. The client's history includes chronic obstructive pulmonary disease (COPD) and coronary artery disease. Because of these history findings, the nurse closely monitors the oxygen flow and the client's respiratory status. Which complication may arise if the client receives a high oxygen concentration? a. Apnea b. Anginal pain c. Respiratory alkalosis d. Metabolic acidosis
Answer A. Hypoxia is the main breathing stimulus for a client with COPD. Excessive oxygen administration may lead to apnea by removing that stimulus. Anginal pain results from a reduced myocardial oxygen supply. A client with COPD may have anginal pain from generalized vasoconstriction secondary to hypoxia; however, administering oxygen at any concentration dilates blood vessels, easing anginal pain. Respiratory alkalosis results from alveolar hyperventilation, not excessive oxygen administration. In a client with COPD, high oxygen concentrations decrease the ventilatory drive, leading to respiratory acidosis, not alkalosis. High oxygen concentrations don't cause metabolic acidosis.
Nurse Murphy administers albuterol (Proventil), as prescribed, to a client with emphysema. Which finding indicates that the drug is producing a therapeutic effect? a. Respiratory rate of 22 breaths/minute b. Dilated and reactive pupils c. Urine output of 40 ml/hour d. Heart rate of 100 beats/minute
Answer A. In a client with emphysema, albuterol is used as a bronchodilator. A respiratory rate of 22 breaths/minute indicates that the drug has achieved its therapeutic effect because fewer respirations are required to achieve oxygenation. Albuterol has no effect on pupil reaction or urine output. It may cause a change in the heart rate, but this is an adverse, not therapeutic, effect.
An unconscious male client is admitted to an emergency room. Arterial blood gas measurements reveal a pH of 7.30, a low bicarbonate level, a normal carbon dioxide level, a normal oxygen level, and an elevated potassium level. These results indicate the presence of: a. Metabolic acidosis b. Respiratory acidosis c. Overcompensated respiratory acidosis d. Combined respiratory and metabolic acidosis
Answer A. In an acidotic condition, the pH would be low, indicating the acidosis. In addition, a low bicarbonate level along with the low pH would indicate a metabolic state. Therefore, options B, C, and D are incorrect.
A male client has been admitted with chest trauma after a motor vehicle accident and has undergone subsequent intubation. A nurse checks the client when the high-pressure alarm on the ventilator sounds, and notes that the client has absence of breathe sounds in right upper lobe of the lung. The nurse immediately assesses for other signs of: a. Right pneumothorax b. Pulmonary embolism c. Displaced endotracheal tube d. Acute respiratory distress syndrome
Answer A. Pneumothorax is characterized by restlessness, tachycardia, dyspnea, pain with respiration, asymmetrical chest expansion, and diminished or absent breath sounds on the affected side. Pneumothorax can cause increased airway pressure because of resistance to lung inflation. Acute respiratory distress syndrome and pulmonary embolism are not characterized by absent breath sounds. An endotracheal tube that is inserted too far can cause absent breath sounds, but the lack of breath sounds most likely would be on the left side because of the degree of curvature of the right and left main stem bronchi.
Nurse Joana is teaching a client with emphysema how to perform pursed-lip breathing. The client asks the nurse to explain the purpose of this breathing technique. Which explanation should the nurse provide? a. It helps prevent early airway collapse. b. It increases inspiratory muscle strength c. It decreases use of accessory breathing muscles. d. It prolongs the inspiratory phase of respiration.
Answer A. Pursed-lip breathing helps prevent early airway collapse. Learning this technique helps the client control respiration during periods of excitement, anxiety, exercise, and respiratory distress. To increase inspiratory muscle strength and endurance, the client may need to learn inspiratory resistive breathing. To decrease accessory muscle use and thus reduce the work of breathing, the client may need to learn diaphragmatic (abdominal) breathing. In pursed-lip breathing, the client mimics a normal inspiratory-expiratory (I:E) ratio of 1:2. (A client with emphysema may have an I:E ratio as high as 1:4.)
A nurse teaches a male client about the use of a respiratory inhaler. Which action by the client indicates a need for further teaching? a. Inhales the mist and quickly exhales b. Removes the cap and shakes the inhaler well before use c. Presses the canister down with the finger as he breathes in d. Waits 1 to 2 minutes between puffs if more than one puff has been prescribed
Answer A. The client should be instructed to hold his or her breath for at least 10 to 15 seconds before exhaling the mist. Options B, C, and D are accurate instructions regarding the use of the inhaler.
A female client is suspected of having a pulmonary embolus. A nurse assesses the client, knowing that which of the following is a common clinical manifestation of pulmonary embolism? a. Dyspnea b. Bradypnea c. Bradycardia d. Decreased respiratory
Answer A. The common clinical manifestations of pulmonary embolism are tachypnea, tachycardia, dyspnea, and chest pain.
A male client with pneumococcal pneumonia is admitted to an acute care facility. The client in the next room is being treated for mycoplasmal pneumonia. Despite the different causes of the various types of pneumonia, all of them share which feature? a. Inflamed lung tissue b. Sudden onset c. Responsiveness to penicillin. d. Elevated white blood cell (WBC) count
Answer A. The common feature of all types of pneumonia is an inflammatory pulmonary response to the offending organism or agent. Although most types of pneumonia have a sudden onset, a few (such as anaerobic bacterial pneumonia and mycoplasmal pneumonia) have an insidious onset. Antibiotic therapy is the primary treatment for most types of pneumonia; however, the antibiotic must be specific for the causative agent, which may not be responsive to penicillin. A few types of pneumonia, such as viral pneumonia, aren't treated with antibiotics. Although pneumonia usually causes an elevated WBC count, some types, such as mycoplasmal pneumonia, don't.
A nurse is caring for a male client immediately after removal of the endotracheal tube. The nurse reports which of the following signs immediately if experienced by the client? a. Stridor b. Occasional pink-tinged sputum c. A few basilar lung crackles on the right d. Respiratory rate of 24 breaths/min
Answer A. The nurse reports stridor to the physician immediately. This is a high-pitched, coarse sound that is heard with the stethoscope over the trachea. Stridor indicates airway edema and places the client at risk for airway obstruction. Options B, C, and D are not signs that require immediate notification of the physician.
For a male client who has a chest tube connected to a closed water-seal drainage system, the nurse should include which action in the plan of care? a. Measuring and documenting the drainage in the collection chamber b. Maintaining continuous bubbling in the water-seal chamber c. Keeping the collection chamber at chest level d. Stripping the chest tube every hour
Answer A. The nurse should measure and document the amount of chest tube drainage regularly to detect abnormal drainage patterns, such as may occur with a hemorrhage (if excessive) or a blockage (if decreased). Continuous bubbling in the water-seal chamber indicates a leak in the closed chest drainage system, which must be corrected. The nurse should keep the collection chamber below chest level to allow fluids to drain into it. The nurse should not strip chest tubes because doing so may traumatize the tissue or dislodge the tube.
A male client who takes theophylline for chronic obstructive pulmonary disease is seen in the urgent care center for respiratory distress. Once the client is stabilized, the nurse begins discharge teaching. The nurse would be especially vigilant to include information about complying with medication therapy if the client's baseline theophylline level was: a. 10 mcg/mL b. 12 mcg/mL c. 15 mcg/mL d. 18mcg/mL
Answer A. The therapeutic range for the serum theophylline level is 10 to 20 mcg/mL. If the level is below the therapeutic range, the client may experience frequent exacerbations of the disorder. Although all the options identify values within the therapeutic range, option A is the option that reflects a need for compliance with medication.
A male client is to receive I.V. vancomycin (Vancocin). When preparing to administer this drug, the nurse should keep in mind that: a. vancomycin should be infused over 60 to 90 minutes in a large volume of fluid. b. vancomycin may cause irreversible neutropenia. c. vancomycin should be administered rapidly in a large volume of fluid. d. vancomycin should be administered over 1 to 2 minutes as an I.V. bolus.
Answer A. To avoid a hypotensive reaction from rapid I.V. administration, the nurse should infuse vancomycin slowly, over 60 to 90 minutes, in a large volume of fluid. Although neutropenia may occur in approximately 5% to 10% of clients receiving vancomycin, this adverse effect reverses rapidly when the drug is discontinued
slightly obese female client with a history of allergy-induced asthma, hypertension, and mitral valve prolapse is admitted to an acute care facility for elective surgery. The nurse obtains a complete history and performs a thorough physical examination, paying special attention to the cardiovascular and respiratory systems. When percussing the client's chest wall, the nurse expects to elicit: a. Resonant sounds. b. Hyperresonant sounds. c. Dull sounds. d. Flat sounds.
Answer A. When percussing the chest wall, the nurse expects to elicit resonant sounds — low-pitched, hollow sounds heard over normal lung tissue. Hyperresonant sounds indicate increased air in the lungs or pleural space; they're louder and lower pitched than resonant sounds. Although hyperresonant sounds occur in such disorders as emphysema and pneumothorax, they may be normal in children and very thin adults. Dull sounds, normally heard only over the liver and heart, may occur over dense lung tissue, such as from consolidation or a tumor. Dull sounds are thudlike and of medium pitch. Flat sounds, soft and high-pitched, are heard over airless tissue and can be replicated by percussing the thigh or a bony structure.
A male client abruptly sits up in bed, reports having difficulty breathing and has an arterial oxygen saturation of 88%. Which mode of oxygen delivery would most likely reverse the manifestations? a. Simple mask b. Non-rebreather mask c. Face tent d. Nasal cannula
Answer B. A non-rebreather mask can deliver levels of the fraction of inspired oxygen (FIO2) as high as 100%. Other modes — simple mask, face tent and nasal cannula — deliver lower levels of FIO2.
Nurse Mickey is administering a purified protein derivative (PPD) test to a homeless client. Which of the following statements concerning PPD testing is true? a. A positive reaction indicates that the client has active tuberculosis (TB). b. A positive reaction indicates that the client has been exposed to the disease. c. A negative reaction always excludes the diagnosis of TB. d. The PPD can be read within 12 hours after the injection.
Answer B. A positive reaction means the client has been exposed to TB; it isn't conclusive of the presence of active disease. A positive reaction consists of palpable swelling and induration of 5 to 15 mm. It can be read 48 to 72 hours after the injection. In clients with positive reactions, further studies are usually done to rule out active disease. In immunosuppressed clients, a negative reaction doesn't exclude the presence of active disease.
A female client with interstitial lung disease is prescribed prednisone (Deltasone) to control inflammation. During client teaching, the nurse stresses the importance of taking prednisone exactly as prescribed and cautions against discontinuing the drug abruptly. A client who discontinues prednisone abruptly may experience: a. hyperglycemia and glycosuria. b. acute adrenocortical insufficiency. c. GI bleeding. d. restlessness and seizures.
Answer B. Administration of a corticosteroid such as prednisone suppresses the body's natural cortisol secretion, which may take weeks or months to normalize after drug discontinuation. Abruptly discontinuing such therapy may cause the serum cortisol level to drop low enough to trigger acute adrenocortical insufficiency. Hyperglycemia, glycosuria, GI bleeding, restlessness, and seizures are common adverse effects of corticosteroid therapy, not its sudden cessation.
Before weaning a male client from a ventilator, which assessment parameter is most important for the nurse to review? a. Fluid intake for the last 24 hours b. Baseline arterial blood gas (ABG) levels c. Prior outcomes of weaning d. Electrocardiogram (ECG) results
Answer B. Before weaning a client from mechanical ventilation, it's most important to have baseline ABG levels. During the weaning process, ABG levels will be checked to assess how the client is tolerating the procedure. Other assessment parameters are less critical. Measuring fluid volume intake and output is always important when a client is being mechanically ventilated. Prior attempts at weaning and ECG results are documented on the client's record, and the nurse can refer to them before the weaning process begins.
A nurse is caring for a male client hospitalized with acute exacerbation of chronic obstructive pulmonary disease. Which of the following would the nurse expect to note on assessment of this client? a. Hypocapnia b. A hyperinflated chest noted on the chest x-ray c. Increase oxygen saturation with exercise d. A widened diaphragm noted on the chest x-ray
Answer B. Clinical manifestations of chronic obstructive pulmonary disease (COPD) include hypoxemia, hypercapnia, dyspnea on exertion and at rest, oxygen desaturation with exercise, and the use of accessory muscles of respiration. Chest x-rays reveal a hyperinflated chest and a flattened diaphragm if the disease is advanced.
Nurse Eve formulates a nursing diagnosis of Activity intolerance related to inadequate oxygenation and dyspnea for a client with chronic bronchitis. To minimize this problem, the nurse instructs the client to avoid conditions that increase oxygen demands. Such conditions include: a. drinking more than 1,500 ml of fluid daily. b. being overweight. c. eating a high-protein snack at bedtime. d. eating more than three large meals a day.
Answer B. Conditions that increase oxygen demands include obesity, smoking, exposure to temperature extremes, and stress. A client with chronic bronchitis should drink at least 2,000 ml of fluid daily to thin mucus secretions; restricting fluid intake may be harmful. The nurse should encourage the client to eat a high-protein snack at bedtime because protein digestion produces an amino acid with sedating effects that may ease the insomnia associated with chronic bronchitis. Eating more than three large meals a day may cause fullness, making breathing uncomfortable and difficult; however, it doesn't increase oxygen demands. To help maintain adequate nutritional intake, the client with chronic bronchitis should eat small, frequent meals (up to six a day).
The nurse caring for a male client with a chest tube turns the client to the side, and the chest tube accidentally disconnects. The initial nursing action is to: a. Call the physician. b. Place the tube in a bottle of sterile water. c. Immediately replace the chest tube system. d. Place the sterile dressing over the disconnection site.
Answer B. If the chest drainage system is disconnected, the end of the tube is placed in a bottle of sterile water held below the level of the chest. The system is replaced if it breaks or cracks or if the collection chamber is full. Placing a sterile dressing over the disconnection site will not prevent complications resulting from the disconnection. The physician may need to be notified, but this is not the initial action.
While changing the tapes on a tracheostomy tube, the male client coughs and the tube is dislodged. The initial nursing action is to: a. Call the physician to reinsert the tube. b. Grasp the retention sutures to spread the opening. c. Call the respiratory therapy department to reinsert the tracheotomy. d. Cover the tracheostomy site with a sterile dressing to prevent infection.
Answer B. If the tube is dislodged accidentally, the initial nursing action is to grasp the retention sutures and spread the opening. If agency policy permits, the nurse then attempts immediately to replace the tube. Covering the tracheostomy site will block the airway. Options 1 and 3 will delay treatment in this emergency situation.
A female client has a tracheostomy but doesn't require continuous mechanical ventilation. When weaning the client from the tracheostomy tube, the nurse initially should plug the opening in the tube for: a. 15 to 60 seconds. b. 5 to 20 minutes. c. 30 to 40 minutes. d. 45 to 60 minutes.
Answer B. Initially, the nurse should plug the opening in the tracheostomy tube for 5 to 20 minutes, and then gradually lengthen this interval according to the client's respiratory status. A client who doesn't require continuous mechanical ventilation already is breathing without assistance, at least for short periods; therefore, plugging the opening of the tube for only 15 to 60 seconds wouldn't be long enough to reveal the client's true tolerance to the procedure. Plugging the opening for more than 20 minutes would increase the risk of acute respiratory distress because the client requires an adjustment period to start breathing normally
The nurse is caring for a male client who recently underwent a tracheostomy. The first priority when caring for a client with a tracheostomy is: a. helping him communicate. b. keeping his airway patent. c. encouraging him to perform activities of daily living. d. preventing him from developing an infection.
Answer B. Maintaining a patent airway is the most basic and critical human need. All other interventions are important to the client's well-being but not as important as having sufficient oxygen to breathe.
A nurse is caring for a male client with emphysema who is receiving oxygen. The nurse assesses the oxygen flow rate to ensure that it does not exceed: a. 1 L/min b. 2 L/min c. 6 L/min d. 10 L/min
Answer B. Oxygen is used cautiously and should not exceed 2 L/min. Because of the long-standing hypercapnia that occurs in emphysema, the respiratory drive is triggered by low oxygen levels rather than increased carbon dioxide levels, as is the case in a normal respiratory system.
A male elderly client is admitted to an acute care facility with influenza. The nurse monitors the client closely for complications. What is the most common complication of influenza? a. Septicemia b. Pneumonia c. Meningitis d. Pulmonary edema
Answer B. Pneumonia is the most common complication of influenza. It may be either primary influenza viral pneumonia or pneumonia secondary to a bacterial infection. Other complications of influenza include myositis, exacerbation of chronic obstructive pulmonary disease, and Reye's syndrome. Myocarditis, pericarditis, transverse myelitis, and encephalitis are rare complications of influenza. Although septicemia may arise when any infection becomes overwhelming, it rarely results from influenza. Meningitis and pulmonary edema aren't associated with influenza.
A black male 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: a. lips. b. mucous membranes. c. nail beds. d. earlobes.
Answer B. Skin color doesn't affect the mucous membranes. The lips, nail beds, and earlobes are less reliable indicators of cyanosis because they're affected by skin color.
Which of the following would be most appropriate for a male client with an arterial blood gas (ABG) of pH 7.5, PaCO2 26 mm Hg, O2 saturation 96%, HCO3 24 mEq/L, and PaO2 94 mm Hg? a. Administer a prescribed decongestant. b. Instruct the client to breathe into a paper bag. c. Offer the client fluids frequently. d. Administer prescribed supplemental oxygen.
Answer B. The ABG results reveal respiratory alkalosis. The best intervention to raise the PaCO2 level would be to have the client breathe into a paper bag. All of the other options — such as administering a decongestant, offering fluids frequently, and administering supplemental oxygen — wouldn't raise the lowered PaCO2 level.
A nurse is caring for a female client diagnosed with tuberculosis. Which assessment, if made by the nurse, is inconsistent with the usual clinical presentation of tuberculosis and may indicate the development of a concurrent problem? a. Cough b. High-grade fever c. Chills and night sweats d. Anorexia and weight loss
Answer B. The client with tuberculosis usually experiences cough (productive or nonproductive), fatigue, anorexia, weight loss, dyspnea, hemoptysis, chest discomfort or pain, chills and sweats (which may occur at night), and a low-grade fever.
A male adult client with cystic fibrosis is admitted to an acute care facility with an acute respiratory infection. Prescribed respiratory treatment includes chest physiotherapy. When should the nurse perform this procedure? a. Immediately before a meal b. At least 2 hours after a meal c. When bronchospasms occur d. When secretions have mobilized
Answer B. The nurse should perform chest physiotherapy at least 2 hours after a meal to reduce the risk of vomiting and aspiration. Performing it immediately before a meal may tire the client and impair the ability to eat. Percussion and vibration, components of chest physiotherapy, may worsen bronchospasms; therefore, the procedure is contraindicated in clients with bronchospasms. Secretions that have mobilized (especially when suction equipment isn't available) are a contraindication for postural drainage, another component of chest physiotherapy.
A nurse has assisted a physician with the insertion of a chest tube. The nurse monitors the adult client and notes fluctuation of the fluid level in the water seal chamber after the tube is inserted. Based on this assessment, which action would be appropriate? a. Inform the physician. b. Continue to monitor the client. c. Reinforce the occlusive dressing. d. Encourage the client to deep-breathe.
Answer B. The presence of fluctuation of the fluid level in the water seal chamber indicates a patent drainage system. With normal breathing, the water level rises with inspiration and falls with expiration. Fluctuation stops if the tube is obstructed, if a dependent loop exists, if the suction is not working properly, or if the lung has reexpanded. Options A, C, and D are incorrect.
An emergency room nurse is assessing a female client who has sustained a blunt injury to the chest wall. Which of these signs would indicate the presence of a pneumothorax in this client? a. A low respiratory b. Diminished breathe sounds c. The presence of a barrel chest d. A sucking sound at the site of injury
Answer B. This client has sustained a blunt or a closed chest injury. Basic symptoms of a closed pneumothorax are shortness of breath and chest pain. A larger pneumothorax may cause tachypnea, cyanosis, diminished breath sounds, and subcutaneous emphysema. Hyperresonance also may occur on the affected side. A sucking sound at the site of injury would be noted with an open chest injury.
Nurse Hannah is preparing to obtain a sputum specimen from a client. Which of the following nursing actions will facilitate obtaining the specimen? a. Limiting fluids b. Having the clients take three deep breaths c. Asking the client to split into the collection container d. Asking the client to obtain the specimen after eating
Answer B. To obtain a sputum specimen, the client should rinse the mouth to reduce contamination, breathe deeply, and then cough into a sputum specimen container. The client should be encouraged to cough and not spit so as to obtain sputum. Sputum can be thinned by fluids or by a respiratory treatment such as inhalation of nebulized saline or water. The optimal time to obtain a specimen is on arising in the morning.
The nursing instructor asks a nursing student to describe the route of transmission of tuberculosis. The instructor concludes that the student understands this information if the student states that the tuberculosis is transmitted by: a. Hand and mouth b. The airborne route c. The fecal-oral route d. Blood and body fluids
Answer B. Tuberculosis is an infectious disease caused by the bacillus Mycobacterium tuberculosis and is spread primarily by the airborne route. Options A, C, and D are incorrect.
A nurse performs an admission assessment on a female client with a diagnosis of tuberculosis. The nurse reviews the results of which diagnostic test that will confirm this diagnosis? a. Bronchoscopy b. Sputum culture c. Chest x-ray d. Tuberculin skin test
Answer B. Tuberculosis is definitively diagnosed through culture and isolation of Mycobacterium tuberculosis. A presumptive diagnosis is made based on a tuberculin skin test, a sputum smear that is positive for acid-fast bacteria, a chest x-ray, and histological evidence of granulomatous disease on biopsy.
A male client with pneumonia develops respiratory failure and has a partial pressure of arterial oxygen of 55 mm Hg. He's placed on mechanical ventilation with a fraction of inspired oxygen (FIO2) of 0.9. The nursing goal should be to reduce the FIO2 to no greater than: a. 0.21 b. 0.35 c. 0.5 d. 0.7
Answer C. An FO2 greater than 0.5 for as little as 16 to 24 hours can be toxic and can lead to decreased gas diffusion and surfactant activity. The ideal oxygen source is room air F IO 2 0.18 to 0.21.
Nurse Oliver observes constant bubbling in the water-seal chamber of a closed chest drainage system. What should the nurse conclude? a. The system is functioning normally b. The client has a pneumothorax. c. The system has an air leak. d. The chest tube is obstructed.
Answer C. Constant bubbling in the chamber indicates an air leak and requires immediate intervention. The client with a pneumothorax will have intermittent bubbling in the water-seal chamber. Clients without a pneumothorax should have no evidence of bubbling in the chamber. If the tube is obstructed, the nurse should notice that the fluid has stopped fluctuating in the water-seal chamber.
For a male client with chronic obstructive pulmonary disease, which nursing intervention would help maintain a patent airway? a. Restricting fluid intake to 1,000 ml/day b. Enforcing absolute bed rest c. Teaching the client how to perform controlled coughing d. Administering prescribed sedatives regularly and in large amounts
Answer C. Controlled coughing helps maintain a patent airway by helping to mobilize and remove secretions. A moderate fluid intake (usually 2 L or more daily) and moderate activity help liquefy and mobilize secretions. Bed rest and sedatives may limit the client's ability to maintain a patent airway, causing a high risk of infection from pooled secretions.
A nurse is suctioning fluids from a female client through an endotracheal tube. During the suctioning procedure, the nurse notes on the monitor that the heart rate is decreasing. Which of the following is the appropriate nursing intervention? a. Continue to suction. b. Notify the physician immediately. c. Stop the procedure and reoxygenate the client. d. Ensure that the suction is limited to 15 seconds.
Answer C. During suctioning, the nurse should monitor the client closely for side effects, including hypoxemia, cardiac irregularities such as a decrease in heart rate resulting from vagal stimulation, mucosal trauma, hypotension, and paroxysmal coughing. If side effects develop, especially cardiac irregularities, the procedure is stopped and the client is reoxygenated.
Before seeing a newly assigned female client with respiratory alkalosis, the nurse quickly reviews the client's medical history. Which condition is a predisposing factor for respiratory alkalosis? a. Myasthenia gravis b. Type 1 diabetes mellitus c. Extreme anxiety d. Narcotic overdose
Answer C. Extreme anxiety may lead to respiratory alkalosis by causing hyperventilation, which results in excessive carbon dioxide (CO2) loss. Other conditions that may set the stage for respiratory alkalosis include fever, heart failure, and injury to the brain's respiratory center, overventilation with a mechanical ventilator, pulmonary embolism, and early salicylate intoxication. Type 1 diabetes mellitus may lead to diabetic ketoacidosis; the deep, rapid respirations occurring in this disorder (Kussmaul's respirations) don't cause excessive CO2 loss. Myasthenia gravis and narcotic overdose suppress the respiratory drive, causing CO2 retention, not CO2 loss; this may lead to respiratory acidosis, not alkalosis.
A female client with chest injury has suffered flail chest. A nurse assesses the client for which most distinctive sign of flail chest? a. Cyanosis b. Hypotension c. Paradoxical chest movement d. Dyspnea, especially on exhalation
Answer C. Flail chest results from fracture of two or more ribs in at least two places each. This results in a "floating" section of ribs. Because this section is unattached to the rest of the bony rib cage, this segment results in paradoxical chest movement. This means that the force of inspiration pulls the fractured segment inward, while the rest of the chest expands. Similarly, during exhalation, the segment balloons outward while the rest of the chest moves inward. This is a telltale sign of flail chest.
A nurse is caring for a female client after a bronchoscope and biopsy. Which of the following signs, if noted in the client, should be reported immediately to the physicians? a. Dry cough b. Hematuria c. Bronchospasm d. Blood-streaked sputum
Answer C. If a biopsy was performed during a bronchoscopy, blood-streaked sputum is expected for several hours. Frank blood indicates hemorrhage. A dry cough may be expected. The client should be assessed for signs of complications, which would include cyanosis, dyspnea, stridor, bronchospasm, hemoptysis, hypotension, tachycardia, and dysrhythmias. Hematuria is unrelated to this procedure.
A male client with chronic obstructive pulmonary disease (COPD) is recovering from a myocardial infarction. Because the client is extremely weak and can't produce an effective cough, the nurse should monitor closely for: a. Pleural effusion. b. Pulmonary edema. c. Atelectasis. d. Oxygen toxicit
Answer C. In a client with COPD, an ineffective cough impedes secretion removal. This, in turn, causes mucus plugging, which leads to localized airway obstruction — a known cause of atelectasis. An ineffective cough doesn't cause pleural effusion (fluid accumulation in the pleural space). Pulmonary edema usually results from left-sided heart failure, not an ineffective cough. Although many noncardiac conditions may cause pulmonary edema, an ineffective cough isn't one of them. Oxygen toxicity results from prolonged administration of high oxygen concentrations, not an ineffective cough.
A nurse is teaching a male client with chronic respiratory failure how to use a metered-dose inhaler correctly. The nurse instructs the client to: a. Inhale quickly b. Inhale through the nose c. Hold the breath after inhalation d. Take two inhalations during one breath
Answer C. Instructions for using a metered-dose inhaler include shaking the canister, holding it right side up, inhaling slowly and evenly through the mouth, delivering one spray per breath, and holding the breath after inhalation.
Pulmonary disease (COPD), which nursing action best promotes adequate gas exchange? a. Encouraging the client to drink three glasses of fluid daily b. Keeping the client in semi-Fowler's position c. Using a high-flow Venturi mask to deliver oxygen as prescribed d. Administering a sedative as prescribed
Answer C. The client with COPD retains carbon dioxide, which inhibits stimulation of breathing by the medullary center in the brain. As a result, low oxygen levels in the blood stimulate respiration, and administering unspecified, unmonitored amounts of oxygen may depress ventilation. To promote adequate gas exchange, the nurse should use a Venturi mask to deliver a specified, controlled amount of oxygen consistently and accurately. Drinking three glasses of fluid daily wouldn't affect gas exchange or be sufficient to liquefy secretions, which are common in COPD. Clients with COPD and respiratory distress should be placed in high Fowler's position and shouldn't receive sedatives or other drugs that may further depress the respiratory center.
A female client is receiving supplemental oxygen. When determining the effectiveness of oxygen therapy, which arterial blood gas value is most important? a. pH b. Bicarbonate (HCO3-) c. Partial pressure of arterial oxygen (PaO2) d. Partial pressure of arterial carbon dioxide (PaCO2)
Answer C. The most significant and direct indicator of the effectiveness of oxygen therapy is the PaO2 value. Based on the PaO2 value, the nurse may adjust the type of oxygen delivery (cannula, venturi mask, or mechanical ventilator), flow rate, and oxygen percentage. The other options reflect the client's ventilation status, not oxygenation.
A male client is admitted to the health care facility for treatment of chronic obstructive pulmonary disease. Which nursing diagnosis is most important for this client? a. Activity intolerance related to fatigue b. Anxiety related to actual threat to health status c. Risk for infection related to retained secretions d. Impaired gas exchange related to airflow obstruction
Answer D. A patent airway and an adequate breathing pattern are the top priority for any client, making impaired gas exchange related to airflow obstruction the most important nursing diagnosis. The other options also may apply to this client but are less important.
A female client has just returned to a nursing unit following bronchoscopy. A nurse would implement which of the following nursing interventions for this client? a. Administering atropine intravenously b. Administering small doses of midazolam (Versed) c. Encouraging additional fluids for the next 24 hours d. Ensuring the return of the gag reflex before offering food or fluids
Answer D. After bronchoscopy, the nurse keeps the client on NPO status until the gag reflex returns because the preoperative sedation and local anesthesia impair swallowing and the protective laryngeal reflexes for a number of hours. Additional fluids are unnecessary because no contrast dye is used that would need flushing from the system. Atropine and midazolam would be administered before the procedure, not after.
A community health nurse is conducting an educational session with community members regarding tuberculosis. The nurse tells the group that one of the first symptoms associated with tuberculosis is: a. Dyspnea b. Chest pain c. A bloody, productive cough d. A cough with the expectoration of mucoid sputum
Answer D. One of the first pulmonary symptoms is a slight cough with the expectoration of mucoid sputum. Options A, B, and C are late symptoms and signify cavitation and extensive lung involvement.
A nurse instructs a female client to use the pursed-lip method of breathing and the client asks the nurse about the purpose of this type of breathing. The nurse responds, knowing that the primary purpose of pursed-lip breathing is to: a. Promote oxygen intake. b. Strengthen the diaphragm. c. Strengthen the intercostal muscles. d. Promote carbon dioxide elimination.
Answer D. Pursed-lip breathing facilitates maximal expiration for clients with obstructive lung disease. This type of breathing allows better expiration by increasing airway pressure that keeps air passages open during exhalation. Options A, B, and C are not the purposes of this type of breathing.
After undergoing a thoracotomy, a male client is receiving epidural analgesia. Which assessment finding indicates that the client has developed the most serious complication of epidural analgesia? a. Heightened alertness b. Increased heart rate c. Numbness and tingling of the extremities d. Respiratory depression
Answer D. Respiratory depression is the most serious complication of epidural analgesia. Other potential complications include hypotension, decreased sensation and movement of the extremities, allergic reactions, and urine retention. Typically, epidural analgesia causes central nervous system depression (indicated by drowsiness) as well as a decreased heart rate and blood pressure.
A nurse is assessing the respiratory status of a male client who has suffered a fractured rib. The nurse would expect to note which of the following? a. Slow deep respirations b. Rapid deep respirations c. Paradoxical respirations d. Pain, especially with inspiration
Answer D. Rib fractures are a common injury, especially in the older client, and result from a blunt injury or a fall. Typical signs and symptoms include pain and tenderness localized at the fracture site and exacerbated by inspiration and palpation, shallow respirations, splinting or guarding the chest protectively to minimize chest movement, and possible bruising at the fracture site. Paradoxical respirations are seen with flail chest.
At 11 p.m., a male client is admitted to the emergency department. He has a respiratory rate of 44 breaths/minute. He's anxious, and wheezes are audible. The client is immediately given oxygen by face mask and methylprednisolone (Depo-medrol) I.V. At 11:30 p.m., the client's arterial blood oxygen saturation is 86% and he's still wheezing. The nurse should plan to administer: a. alprazolam (Xanax). b. propranolol (Inderal) c. morphine. d. albuterol (Proventil).
Answer D. The client is hypoxemic because of bronchoconstriction as evidenced by wheezes and a subnormal arterial oxygen saturation level. The client's greatest need is bronchodilation, which can be accomplished by administering bronchodilators. Albuterol is a beta2 adrenergic agonist, which causes dilation of the bronchioles. It's given by nebulization or metered-dose inhalation and may be given as often as every 30 to 60 minutes until relief is accomplished. Alprazolam is an anxiolytic and central nervous system depressant, which could suppress the client's breathing. Propranolol is contraindicated in a client who's wheezing because it's a beta2 adrenergic antagonist. Morphine is a respiratory center depressant and is contraindicated in this situation.
A nurse is assessing a female client with multiple trauma who is at risk for developing acute respiratory distress syndrome. The nurse assesses for which earliest sign of acute respiratory distress syndrome? a. Bilateral wheezing b. Inspiratory crackles c. Intercostal retractions d. Increased respiratory rate
Answer D. The earliest detectable sign of acute respiratory distress syndrome is an increased respiratory rate, which can begin from 1 to 96 hours after the initial insult to the body. This is followed by increasing dyspnea, air hunger, retraction of accessory muscles, and cyanosis. Breath sounds may be clear or consist of fine inspiratory crackles or diffuse coarse crackles.
A female client is undergoing a complete physical examination as a requirement for college. When checking the client's respiratory status, the nurse observes respiratory excursion to help assess: a. Lung vibrations. b. Vocal sounds. c. Breath sounds. d. Chest movements.
Answer D. The nurse observes respiratory excursion to help assess chest movements. Normally, thoracic expansion is symmetrical; unequal expansion may indicate pleural effusion, atelectasis, pulmonary embolus, or a rib or sternum fracture. The nurse assesses vocal sounds to evaluate air flow when checking for tactile fremitus; after asking the client to say "99," the nurse palpates the vibrations transmitted from the bronchopulmonary system along the solid surfaces of the chest wall to the nurse's palms. The nurse assesses breath sounds during auscultation.
