A) A tube is passed into the mouth and through the larynx B) A tube is passed through the nose and into the trachea C) A puncture is made through the cricothyroid cartilage D) A surgical incision is made into the trachea

D) A surgical incision is made into the trachea

A client with chest trauma has ABGs drawn. The nurse anticipates which scenario upon ABG analysis? A) Respiratory alkalosis B) Respiratory acidosis C) Metabolic acidosis D) Metabolic alkalosis

B) Respiratory acidosis Chest trauma usually correlates with breathing difficulties. The nurse would anticipate respiratory acidosis upon analysis of the client's ABG results.

Which of the following is a common finding in an open pneumothorax? a) A flail chest b) Trachea deviated to the side of the injury c) Trachea deviated to the side opposite the injury d) A sucking sound on inspiration and expiration

d) A sucking sound on inspiration and expiration In an open pneumothorax, there is an open wound to the outside so a sucking sound is heard on inspiration and expiration.

D) End tidal CO2 monitoring End tidal CO2 monitoring is the first intervention to determine if the endotracheal tube is in place, but a chest x-ray is still needed to confirm proper placement.

A patient is admitted with the diagnosis of severe left-sided heart failure. The nurse expects to auscultate which adventitious lung sounds? A: Sonorous wheezes in the left lower lung B: Rhonchi midsternumC: Crackles only in apex of lungs D: Inspiratory crackles in lung bases

D: Inspiratory crackles in lung bases

Which action will the nurse plan to take for a patient who is scheduled for pulmonary function testing (PFT)? a. Explain reasons for NPO status. b. Administer sedative drug before PFT. c. Assess pulse and BP after the procedure. d. Teach deep inhalation and forceful exhalation.

d. Teach deep inhalation and forceful exhalation. For PFT, the patient should inhale deeply and exhale as long, hard, and fast as possible. The other actions are not needed with PFT.

The nurse is assessing a client who presented to the emergency room for shortness of breath. The client states, "I just cannot breath deeply, it feels like there is someone holding my ribs tight." What is the priority for this client? A) Check the client's airway B) Get an EKG (ECG) C) Tell the client to take a deep breath D) Call a rapid response

B) Get an EKG (ECG) Chest pressure can indicate a myocardial infarction. This client is able to speak a complete sentence, so the client has an airway and is breathing. The nurse will need to contact the provider for an EKG (ECG) right away.

The nurse is caring for a Spanish-speaking client admitted for exacerbation of chronic obstructive pulmonary disease (COPD). The client speaks very little English and is a smoker. Which action would be the most beneficial for this client? A) Have the adult child of the client translate during the assessment process B) Encourage aerobic activity C) Encourage the client to write down questions prior to seeing the healthcare provider D) Obtain educational materials about smoking cessation written in Spanish.

D) Obtain educational materials about smoking cessation written in Spanish. A Spanish-speaking client who smokes and is diagnosed with COPD requires information regarding smoking cessation. For clients who do not speak English, it is appropriate for the nurse to obtain written education material for the client in the client's native language, Spanish.

A nurse providing care of a patient's chest drainage system observes that the chest tube has become separated from the drainage device. What would be the first action that should be taken by the nurse in this situation? A. Notify the health care provider. B. Apply an occlusive dressing on the site. C. Assess the patient for signs of respiratory distress. D. Put on gloves and insert the chest tube in a bottle of sterile saline.

D. Put on gloves and insert the chest tube in a bottle of sterile saline. When a chest tube becomes separated from the drainage device, the nurse should submerge the end in water, creating a water seal, but allowing air to escape, until a new drainage unit can be attached. This is done instead of clamping to prevent another pneumothorax. Then the nurse should assess vital signs and notify the health care provider.

Which of the following statements made by a student nurse indicates the need for further teaching about suctioning a patient with an endotracheal tube? A: "Suctioning the patient requires sterile technique." B: "I'll apply suction while rotating and withdrawing the suction catheter." C: "I'll suction the mouth after I suction the endotracheal tube." D: "I'll instill 5 mL of normal saline into the tube before hyperoxygenating the patient."

D: "I'll instill 5 mL of normal saline into the tube before hyperoxygenating the patient."

When auscultating a patients chest while the patient takes a deep breath, the nurse hears loud, high-pitched, blowing sounds at both lung bases. The nurse will document these as a. normal sounds. b. vesicular sounds. c. abnormal sounds. d. adventitious sounds.

c. abnormal sounds. The description indicates that the nurse hears bronchial breath sounds that are abnormal when heard at the lung base. Adventitious sounds are extra breath sounds such as crackles, wheezes, rhonchi, and friction rubs. Vesicular sounds are low-pitched, soft sounds heard over all lung areas except the major bronchi.

When preparing the patient with a right-sided pleural effusion for a thoracentesis, how will the nurse position the patient? a. Supine with the head of the bed elevated 45 degrees b. In the Trendelenburg position with both arms extended c. On the left side with the right arm extended above the head d. Sitting upright with the arms supported on an over bed table

d. Sitting upright with the arms supported on an over bed table The upright position with the arms supported increases lung expansion, allows fluid to collect at the lung bases, and expands the intercostal space so that access to the pleural space is easier. The other positions would increase the work of breathing for the patient and make it more difficult for the health care provider performing the thoracentesis.

Of the following instructions, which is most important for the nurse to teach the client to help loosen secretions and increase comfort during medical treatment for sinusitis? a. blow the nose frequently b. elevate the head of the bed by 45 degrees c. engage in normal activity d. increase fluid intake

d. increase fluid intake the nurse needs to inform the client receiving medical treatment for sinusitis that use of mouthwashes and humidification as well as increased fluid intake may loosen secretions and increase comfort; the nurse should also instruct the client to take nasal decongestants and antihistamines as ordered.

The nurse is caring for a patient who has decreased mobility. Which intervention is a simple and cost-effective method for reducing the risks of stasis of pulmonary secretions and decreased chest wall expansion? A: Antibiotics B: Frequent change of position C: Oxygen humidification D: Chest physiotherapy

B: Frequent change of position

The nurse understands that this patient has an increased risk for being diagnosed with which disorder: A: Alcoholism and hypertension B: Obesity and diabetes C: Stress-related illnesses D: Cardiopulmonary disease and lung cancer

D: Cardiopulmonary disease and lung cancer

The nurse is caring for a patient who exhibits labored breathing and uses accessory muscles. The patient has crackles in both lung bases and diminished breath sounds. Which would be priority assessments for the nurse to perform? (Select all that apply.) A: SpO2 levels B: Amount of sputum production C: Change in respiratory rate and pattern D: Pain in lower calf area

A: SpO2 levels B: Amount of sputum production C: Change in respiratory rate and pattern

The nurse obtains this information when assessing a patient with chronic obstructive pulmonary disease (COPD) who has been admitted with increasing dyspnea over the last 3 days. Which finding is most important to report to the health care provider? a. Respirations are 36 breaths/minute. b. Anterior-posterior chest ratio is 1:1. c. Lung expansion is decreased bilaterally. d. Hyperresonance to percussion is present.

a. Respirations are 36 breaths/minute. The increase in respiratory rate indicates respiratory distress and a need for rapid interventions such as administration of oxygen or medications. The other findings are common chronic changes occurring in patients with COPD.

A patient with acute shortness of breath is admitted to the hospital. Which action should the nurse take during the initial assessment of the patient? a. Complete a full physical examination to determine the systemic effect of the respiratory distress. b. Obtain a comprehensive health history to determine the extent of any prior respiratory problems. c. Delay the physical assessment and ask family members about any history of respiratory problems. d. Perform a respiratory system assessment and ask specific questions about this episode of respiratory distress.

d. Perform a respiratory system assessment and ask specific questions about this episode of respiratory distress.When a patient has severe respiratory distress, only information pertinent to the current episode is obtained, and a more thorough assessment is deferred until later. Obtaining a comprehensive health history or full physical examination is unnecessary until the acute distress has resolved. A focused physical assessment should be done rapidly to help determine the cause of the distress and suggest treatment. Although family members may know about the patients history of medical problems, the patient is the best informant for these data.

A hypothermic patient is admitted to the emergency department, and pulse oximetry (SpO2) indicates that the O2 saturation is 94%. Which action should the nurse take next? a. Initiate rewarming of the patient. b. Complete a head-to-toe assessment. c. Obtain arterial blood gases (ABGs). d. Place the patient on high-flow oxygen.

d. Place the patient on high-flow oxygen. Although the O2 saturation is adequate, the left shift in the oxyhemoglobin dissociation curve will decrease the amount of oxygen delivered to tissues, so high oxygen concentrations should be given until the patient is normothermic. The other actions also are appropriate, but the initial action should be to administer oxygen.

The nurse has just received arterial blood gas (ABG) results on four patients. Which result is most important to report rapidly to the health care provider? a. pH 7.34, PaO2 82 mm Hg, PaCO2 40 mm Hg, and O2 sat 97% b. pH 7.35, PaO2 85 mm Hg, PaCO2 45 mm Hg, and O2 sat 95% c. pH 7.46, PaO2 90 mm Hg, PaCO2 32 mm Hg, and O2 sat 98% d. pH 7.31, PaO2 91 mm Hg, PaCO2 50 mm Hg, and O2 sat 96%

d. pH 7.31, PaO2 91 mm Hg, PaCO2 50 mm Hg, and O2 sat 96% These ABGs indicate uncompensated respiratory acidosis and should be reported to the health care provider. The other values are normal or close to normal.

The nurse is caring for a client with asthma who must receive regular breathing treatments. Which of the following are adverse drug reactions for bronchodilators? Select all that apply. A) Headache B) Sneezing C) Tachycardia D) Palpitations E) Back pain

A) Headache C) Tachycardia D) Palpitations Common adverse reactions for bronchodilators include allergic reactions such as a rash, hives or itching, headache, tachycardia, restlessness, and palpitations.

A nurse is caring for a client who is receiving chest physiotherapy (CPT). Which of the following is the desired outcome of this treatment? A) Loosen secretions and re-inflate alveoli B) Reduce intrapulmonary pressure C) Reduce alveolar pressure D) Drain fluid from the pleural space

A) Loosen secretions and re-inflate alveoli CPT involves using vibrations to loosen secretions. It may be in the form of cupping, using a vest that vibrates, or activating the bed setting (on certain beds) to vibrate. Once mobilized, the client can expel the secretions and inhale deeply to re-inflate the alveoli.

What are strategies to prevent Ventilator-associated Pneumonia? (select all that apply) A. Oral care every 4 hours, B. HOB elevated 30-45 degrees unless contraindicated by the patient's condition C. HOB elevated 10-15 degrees, unless contraindicated by the patient's condition D. Allow family to suction patient as needed to remove secretions

A. Oral care Q4h B. HOB elevated 30-45 degrees unless contraindicated by patients condition

A 6-year-old boy is admitted to the pediatric unit with chills and a fever of 104°F (40°C). What physiological process explains why the child is at risk for developing dyspnea? A: Fever increases metabolic demands, requiring increased oxygen need. B: Blood glucose stores are depleted, and the cells do not have energy to use oxygen. C: Carbon dioxide production increases as result of hyperventilation. D: Carbon dioxide production decreases as a result of hypoventilation.

A: Fever increases metabolic demands, requiring increased oxygen need.

The nurse needs to apply oxygen to a patient who has a precise oxygen level prescribed. Which of the following oxygen-delivery systems should the nurse select to administer the oxygen to the patient? A: Nasal cannula B: Venturi mask C: Simple face mask without inflated reservoir bag D: Plastic face mask with inflated reservoir bag

A: Nasal cannula

The nurse goes to assess a new patient and finds him lying supine in bed. The patient tells the nurse that he feels short of breath. Which nursing action should the nurse perform first? A: Raise the head of the bed to 45 degrees. B: Take his oxygen saturation with a pulse oximeter. C: Take his blood pressure and respiratory rate. D: Notify the health care provider of his shortness of breath

A: Raise the head of the bed to 45 degrees.

Two hours after surgery the nurse assesses a patient who had a chest tube inserted during surgery. There is 200 mL of dark-red drainage in the chest tube at this time. What is the appropriate action for the nurse to perform? A: Record the amount and continue to monitor drainage B: Notify the health care provider C: Strip the chest tube starting at the chest D: Increase the suction by 10 mm Hg

A: Record the amount and continue to monitor drainage

A: Sharp pleuritic pain that worsens on inspiration B: Crackles over lung bases of affected lung C: Tracheal deviation toward the affected lung D: Increased diaphragmatic excursion on side of rib fractures

A: Sharp pleuritic pain that worsens on inspiration

While checking vital signs on an adult client admitted to the hospital from home, the nurse notes that the client's oxygen saturation level is 95% on room air. Which action of the nurse is most appropriate? A) Place the client in the Trendelenburg position B) Continue to monitor and assess for changes C) Provide heated and humidified oxygen via nasal cannula D) Administer 100 percent oxygen by facemask

B) Continue to monitor and assess for changes A desirable oxygen saturation level is between 95 and 100 percent for an adult. If the client has an oxygen saturation of 95 percent on room air, the nurse should continue to monitor for changes in respiratory status.

A female client presents to the ER reporting difficulty breathing. Upon assessment, the client reports "it feels like it's squeezing all around my ribs when I try to take a deep breath and it's making me nauseous." What is the priority nursing intervention for this patient? A) Auscultate lung sounds B) Obtain a 12-lead EKG C) Check a blood pressure D) Apply oxygen

B) Obtain a 12-lead EKG The priority will be to obtain a 12-lead EKG. Because female clients tend to report atypical cardiac symptoms when having a myocardial infarction, it is imperative to rule out MI in this client.

A 23-year-old client requires chest physiotherapy while in the hospital for treatment for cystic fibrosis. The nurse assists the respiratory therapist by helping the client with postural drainage. Which of the following actions best describes this process? A) Encourage the client to cough and deep breathe B) Place the client in Trendelenburg position C) Teach the client how to clap or percuss the affected area D) Assist the client to sit up in bed at a 90-degree angle

B) Place the client in Trendelenburg position Chest physiotherapy involves working with the client to loosen and expectorate secretions in the respiratory system. Postural drainage involves placing the client into a position in which the trachea is lower than the affected area of the lung so the secretions will drain. The client remains in this position for a period of time to allow secretions to drain into the main bronchus and the trachea and then the secretions are removed through suctioning or expectoration.

A patient is admitted to the emergency department with suspected carbon monoxide poisoning. Even though the patient's color is ruddy, not cyanotic, the nurse understands that the patient is at a risk for decreased oxygen-carrying capacity of blood because carbon monoxide does which of the following: A: Stimulates hyperventilation, causing respiratory alkalosis B: Forms a strong bond with hemoglobin, creating a functional anemia. C: Stimulates hypoventilation, causing respiratory acidosis D: Causes alveoli to overinflate, leading to atelectasis

B: Forms a strong bond with hemoglobin, creating a functional anemia.

The low tidal volume alarm on a client's ventilator keeps sounding. What is the nurse's first action? A) Manually ventilate the client. B) Put air into the endotracheal tube cuff. C) Check ventilator connections. D) Call the physician.

C) Check ventilator connections Ventilator connections should be check initially and loose connections or disconnections should be fixed. If there is no immediate problem found, the client should be manually ventilated and another person should check the ventilator connections. Test Plan: Management of care

During shift report, the oncoming nurse is told that an assigned client has atelectasis. The nurse knows this could be caused by which of the following? Select all that apply. A) Brain aneurysm B) Ventricular tachycardia C) Intubation during general anesthesia D) Deep vein thrombosis E) Collapsed lung

C) Intubation during general anesthesia E) Collapsed lung When a client is intubated, a machine breathes for the client. Normally a person's diaphragm contracts, which increases the space in the chest cavity and causes air to enter the lungs. When intubated, a machine forces air into the lungs, which is the opposite mechanism for lung inflation than normal, and can cause a certain measure of obstruction. Clients who are intubated nearly always have some amount of atelectasis afterward. A person with a collapsed lung will have atelectasis in the affected area.

A preceptor asks a student nurse where carbon dioxide and oxygen exchange occurs in the lungs. Which response is correct? A) The atrium B) The pulmonary veins C) The alveoli D) The alveolar ducts

C) The alveoli Gas exchange occurs in the alveoli. The alveoli are the functional unit of the lungs.

A patient is admitted with severe lobar pneumonia. Which of the following assessment findings would indicate that the patient needs airway suctioning? A: Coughing up thick sputum only occasionally B: Coughing up thin, watery sputum easily after nebulization C: Decreased independent ability to cough D: Lung sounds clear only after coughing

C: Decreased independent ability to cough

Which nursing intervention is appropriate for preventing atelectasis in the postoperative patient? A: Postural drainage B: Chest percussion C: Incentive spirometer D: Suctioning

C: Incentive spirometer

A patient has been newly diagnosed with emphysema. In discussing his condition with the nurse, which of his statements would indicate a need for further education? A: "I'll make sure that I rest between activities so I don't get so short of breath." B: "I'll rest for 30 minutes before I eat my meal." C: "If I have trouble breathing at night, I'll use two to three pillows to prop up." D: "If I get short of breath, I'll turn up my oxygen level to 6 L/min."

D: "If I get short of breath, I'll turn up my oxygen level to 6 L/min."

A nurse is caring for a client after having a tracheostomy placed. Which of the following are appropriate nursing interventions for the client with a tracheostomy? a) Hyperoxygenate the client prior to suctioning b) Ensure that the cuff is deflated during meals c) Monitor arterial blood gases rather than pulse oximetry d)Insert the plug into the tracheostomy tube prior to removing the inner cannula

a) Hyperoxygenate the client prior to suctioning When a client has a tracheostomy tube, it will need to be suctioned regularly to prevent airflow occlusion. Each time the tracheostomy is suctioned, the client's oxygen level will drop because they are unable to take a breath. It is important to hyperoxygenate the client prior to suctioning the tracheostomy tube.

A client comes to the doctor's office describing shortness of breath and strange breath sounds when inhaling deeply. Upon auscultation of the lung fields, sibilant wheezes are noted. Which of the following statements by the nurse most correct? a. "Wheezes result from air passing through narrowed passages." b. "Wheezes result from air escaping through a pneumothorax." c. "Wheezes result from air collecting in the pleural cavity." d. "Wheezes result from air between visceral and parietal pleurae."

a. "Wheezes result from air passing through narrowed passages." wheezes may be sibilant (hissing/whistling) or sonorous (full and deep). Sibilant wheezes (formerly called wheezes) are continuous musical sounds that can be heard during inspiration and expiration; and result from air passing through narrowed or partially obstructed air passages and are heard in clients with increased secretions.

A patient with chronic hypoxemia (SaO2 levels of 89% to 90%) caused by chronic obstructive pulmonary disease (COPD) has been hospitalized with increasing shortness of breath. In planning for discharge, which of these actions by the nurse will be most effective in improving compliance with discharge teaching? a. Arrange for the patients spouse to be present during the teaching. b. Start giving the patient discharge teaching on the day of admission. c. Accomplish the patient teaching just before the scheduled discharge. d. Have the patient repeat the instructions immediately after the teaching.

a. Arrange for the patients spouse to be present during the teaching. Hypoxemia interferes with the patients ability to learn and retain information, so having the patients spouse present will increase the likelihood that discharge instructions will be followed. Having the patient repeat the instructions will indicate that the information is understood at the time, but it does not guarantee retention of the information. Because the patient is likely to be distracted just before discharge, giving discharge instructions just before discharge is not ideal. The patient is likely to be anxious and even more hypoxemic than usual on the day of admission, so teaching about discharge should be postponed.

The nurse is caring for a client who has been brought to the ED for an asthma exacerbation. Which of the following would NOT be an expected finding when completing a comprehensive respiratory assessment of this client? a) Tachypnea b) Cheyne-Stokes respirations c) Wheezes d) Diminished breath sounds

b) Cheyne-Stokes respirations This is an abnormal respiratory pattern with periods of apnea. It is not an expected clinical finding in a client experiencing an acute asthma exacerbation. All other assessment findings would be expected with this clinical picture.

A nurse is working in the ED and has just received a client with an asthma exacerbation. Which of the following positions would be the MOST conducive to effective gas exchange for this client? a) Trendelenburg b) High-Fowler's c) Prone d) Dorsal Recumbant

b) High-Fowler's High-Fowler's - client sitting straight upright which would best facilitate breathing and gas exchange in a client with an asthma exacerbation.

A patient with a chronic cough has a bronchoscopy. Which action will be included in the nursing care plan after the procedure? a. Elevate the head of the bed to 80 to 90 degrees. b. Keep the patient NPO until the gag reflex returns. c. Place on bed rest for at least 4 hours postbronchoscopy. d. Notify the health care provider about blood-tinged mucus.

b. Keep the patient NPO until the gag reflex returns. Because a local anesthetic is used to suppress the gag/cough reflexes during bronchoscopy, the nurse should monitor for the return of these reflexes before allowing the patient to take oral fluids or food. Blood-tinged mucus is not uncommon after bronchoscopy. The patient does not need to be on bed rest, and the head of the bed does not need to be in the high-Fowlers position.

A patient is admitted with a metabolic acidosis of unknown origin. Based on this diagnosis, the nurse would expect the patient to have a. intercostal retractions. b. Kussmaul respirations. c. a low oxygen saturation (SpO2). d. a decrease in venous O2 pressure.

b. Kussmaul respirations. Kussmaul (deep and rapid) respirations are a compensatory mechanism for metabolic acidosis. Intercostal retractions, a low oxygen saturation rate, and a decrease in PvO2 would not be caused by acidosis.

When the nurse is analyzing the results of a patients arterial blood gases (ABGs), which finding indicates the need for most immediate action? a. The arterial oxygen saturation (SaO2) is 92%. b. The partial pressure of oxygen in arterial blood (PaO2) is 59 mm Hg. c. The partial pressure of CO2 in arterial blood (PaCO2) is 31 mm Hg. d. The bicarbonate level (HCO3) is 29 mEq/L.

b. The partial pressure of oxygen in arterial blood (PaO2) is 59 mm Hg. All the values are abnormal, but the low PaO2 indicates that the patient is at the point on the oxyhemoglobin dissociation curve where a small change in the PaO2 will cause a large drop in the O2 saturation and a decrease in tissue oxygenation. The nurse should intervene immediately to improve the patients oxygenation.

On auscultation of a patients lungs, the nurse hears short, high-pitched sounds during exhalation in the lower 1/3 of both lungs. The nurse records this finding as a. expiratory crackles at the bases. b. expiratory wheezes in both lungs. c. abnormal lung sounds in the bases of both lungs. d. pleural friction rub in the right and left lower lobes.

b. expiratory wheezes in both lungs. Wheezes are high-pitched sounds. In this case they are heard during the expiratory phase of the respiratory cycle. Abnormal breath sounds are either bronchial or bronchovesicular sounds heard in the peripheral lung fields. Crackles are low-pitched, bubbling sounds. Pleural friction rubs are grating sounds that are usually heard during both inspiration and expiration.

A nurse needs to obtain a sputum specimen from an adult client. Which nursing action will best facilitate obtaining the specimen? a. ask the client to spit into the collection container b. have the client take deep breaths c. restrict the client's fluids d. wait until after the client has eaten to get the specimen.

b. have the client take deep breaths collecting a sputum specimen have the client rinse their mouth with tap water; instruct the client to take several deep breaths, cough forcefully, and expectorate into the container.

Movement of air into and out of the lungs sufficient to maintain normal arterial oxygen and carbon dioxide tensions is termed what? a. perfusion b. ventilation c. diffusion d. inspiration

b. ventilation ventilation is the actual movement of air in and out of the respiratory tract. This process requires a patent airway and intact and functioning respiratory muscles.

After the nurse has received change-of-shift report, which of these patients should be assessed first? a. A patient with pneumonia who has crackles in the right lung base b. A patient with chronic obstructive pulmonary disease (COPD) and pulmonary function testing (PFT) that indicates low forced vital capacity c. A patient with possible lung cancer who has just returned after bronchoscopy d. A patient with hemoptysis and a 16-mm induration with tuberculin skin testing

c. A patient with possible lung cancer who has just returned after bronchoscopy Since the cough and gag are decreased after bronchoscopy, this patient should be assessed for airway maintenance. The other patients do not have clinical manifestations or procedures that require immediate assessment by the nurse.

The nurse palpates the posterior chest while the patient says 99 and notes that no vibration is felt. How should this be charted? a. Diminished expansion b. Dullness to percussion c. Absent tactile fremitus d. Decreased breath sounds

c. Absent tactile fremitus To assess for tactile fremitus, the nurse should use the palms of the hands to assess for vibration when the patient repeats a word or phrase such as 99. Different techniques are used to assess for dullness to percussion, decreased breath sounds, and diminished expansion.

While caring for a patient with respiratory disease, the nurse observes that the patients SpO2 drops from 92% to 88% while the patient is ambulating in the hallway. Which action should the nurse take next? a. Notify the health care provider. b. Document the response to exercise. c. Administer the PRN supplemental O2. d. Encourage the patient to pace activity.

c. Administer the PRN supplemental O2. The drop in SpO2 to 85% indicates that the patient is hypoxemic and needs supplemental oxygen when exercising. The other actions also are appropriate, but the first action should be to correct the hypoxemia.

When assessing the respiratory system of a 78-year-old patient, which finding indicates that the nurse should take immediate action? a. The chest appears barrel shaped. b. The patient has a weak cough effort. c. Crackles are heard from the lung bases to the midline. d. Hyperresonance is present across both sides of the chest.

c. Crackles are heard from the lung bases to the midline. Crackles in the lower half of the lungs indicate that the patient may have an acute problem such as heart failure. The nurse should immediately accomplish further assessments, such as oxygen saturation, and notify the health care provider. A barrel-shaped chest, hyperresonance to percussion, and a weak cough effort are associated with aging. Further evaluation may be needed, but immediate action is not indicated.

The nurse completes a shift assessment on a patient admitted in the early phase of heart failure. When auscultating the patients lungs, which finding would the nurse most likely hear? a. Continuous rumbling, snoring, or rattling sounds mainly on expiration b. Continuous high-pitched musical sounds on inspiration and expiration c. Discontinuous, high-pitched sounds of short duration heard on inspiration d. A series of long-duration, discontinuous, low-pitched sounds during inspiration

c. Discontinuous, high-pitched sounds of short duration heard on inspiration Fine crackles are likely to be heard in the early phase of heart failure. Fine crackles are discontinuous, high- pitched sounds of short duration heard on inspiration. Rhonchi are continuous rumbling, snoring, or rattling sounds mainly on expiration. Course crackles are a series of long-duration, discontinuous, low-pitched sounds during inspiration. Wheezes are continuous high-pitched musical sounds on inspiration and expiration.

The nurse is observing a student who is listening to a patients lungs. Which action by the student indicates a need to review respiratory assessment skills? a. The student compares breath sounds from side to side. b. The student listens only over the posterior part of the chest. c. The student places the stethoscope over the scapulae and then auscultates. d. The student starts at the base of the posterior lung and moves to the apices.

c. The student places the stethoscope over the scapulae and then auscultates. The stethoscope should be placed over lung tissue, not over bony structures.
