endotracheal intubation image
*Note: endotracheal is NOT a tracheostomy
What therapy is provided to a patient with acute respiratory distress syndrome (ARDS)? 1. Mechanical ventilation 2. Oxygen via a Venturi mask 3. Oxygen via a non-rebreather mask 4. Small volume nebulizer treatments
1 A patient with acute respiratory distress syndrome (ARDS) would be intubated and receive mechanical ventilation. Small volume nebulizer treatments would open airways; however, this intervention will not sufficiently treat ARDS. Oxygen via a Venturi mask or a non-rebreather mask would be insufficient to promote oxygenation and perfusion. Text Reference - p. 1651
Which information about a patient who is receiving cisatracurium (Nimbex) to prevent asynchronous breathing with the positive pressure ventilator requires action by the nurse? a. No sedative has been ordered for the patient. b. The patient does not respond to verbal stimulation. c. There is no cough or gag reflex when the patient is suctioned. d. The patient's oxygen saturation remains between 90% to 93%.
ANS: A Because neuromuscular blockade is extremely anxiety provoking, it is essential that patients who are receiving neuromuscular blockade receive concurrent sedation and analgesia. Absence of response to stimuli is expected in patients receiving neuromuscular blockade. The O2 saturation is adequate. DIF: Cognitive Level: Apply (application) REF: 1619
A nurse is caring for a patient who is orally intubated and receiving mechanical ventilation. To decrease the risk for ventilator-associated pneumonia, which action will the nurse include in the plan of care? a. Elevate head of bed to 30 to 45 degrees. b. Give enteral feedings at no more than 10 mL/hr. c. Suction the endotracheal tube every 2 to 4 hours. d. Limit the use of positive end-expiratory pressure.
ANS: A Elevation of the head decreases the risk for aspiration. Positive end-expiratory pressure is frequently needed to improve oxygenation in patients receiving mechanical ventilation. Suctioning should be done only when the patient assessment indicates that it is necessary. Enteral feedings should provide adequate calories for the patient's high energy needs. DIF: Cognitive Level: Apply (application) REF: 1616
A patient with acute respiratory distress syndrome (ARDS) and acute kidney injury has the following drugs ordered. Which drug should the nurse discuss with the health care provider before giving? a. gentamicin 60 mg IV b. pantoprazole (Protonix) 40 mg IV c. sucralfate (Carafate) 1 g per nasogastric tube d. methylprednisolone (Solu-Medrol) 60 mg IV
ANS: A Gentamicin, which is one of the aminoglycoside antibiotics, is potentially nephrotoxic, and the nurse should clarify the drug and dosage with the health care provider before administration. The other drugs are appropriate for the patient with ARDS. DIF: Cognitive Level: Apply (application) REF: 1623
When admitting a patient with possible respiratory failure and a high PaCO2, which assessment information should be immediately reported to the health care provider? a. The patient is very somnolent. b. The patient complains of weakness. c. The patient's blood pressure is 164/98. d. The patient's oxygen saturation is 90%.
ANS: A Increasing somnolence (aka drowsiness) will decrease the patient's respiratory rate and further increase the PaCO2 and respiratory failure. Rapid action is needed to prevent respiratory arrest. An SpO2 of 90%, weakness, and elevated blood pressure all require ongoing monitoring but are not indicators of possible impending respiratory arrest. REF: 1615
A nurse is caring for a patient with acute respiratory distress syndrome (ARDS) who is receiving mechanical ventilation using synchronized intermittent mandatory ventilation (SIMV). The settings include fraction of inspired oxygen (FIO2) of 80%, tidal volume of 450, rate of 16/minute, and positive end-expiratory pressure (PEEP) of 5 cm. Which assessment finding is most important for the nurse to report to the health care provider? a. O2 saturation of 99% b. Heart rate 106 beats/minute c. Crackles audible at lung bases d. Respiratory rate 22 breaths/minute
ANS: A The FIO2 of 80% increases the risk for O2 toxicity. Because the patient's O2 saturation is 99%, a decrease in FIO2 is indicated to avoid toxicity. The other patient data would be typical for a patient with ARDS and would not be the most important data to report to the health care provider. DIF: Cognitive Level: Analyze (analysis) REF: 1616
The nurse is caring for a patient who arrived in the emergency department with acute respiratory distress. Which assessment finding by the nurse requires the most rapid action? a. The patient's PaO2 is 45 mm Hg. b. The patient's PaCO2 is 33 mm Hg. c. The patient's respirations are shallow. d. The patient's respiratory rate is 32 breaths/min.
ANS: A The PaO2 indicates severe hypoxemia and respiratory failure. Rapid action is needed to prevent further deterioration of the patient. Although the shallow breathing, rapid respiratory rate, and low PaCO2 also need to be addressed, the most urgent problem is the patient's poor oxygenation. Normal Values: PaO2: 75 - 100 mmHg PaCO2: 35 - 45 mmHg Arterial blood pH: 7.35 to 7.45 SaO2: 94% - 100%
The nurse is caring for a patient who is intubated and receiving positive pressure ventilation to treat acute respiratory distress syndrome (ARDS). Which finding is most important to report to the health care provider? a. Red-brown drainage from nasogastric tube b. Blood urea nitrogen (BUN) level 32 mg/dL c. Scattered coarse crackles heard throughout lungs d. Arterial blood gases: pH of 7.31, PaCO2 of 50, and PaO2 of 68
ANS: A The nasogastric drainage indicates possible gastrointestinal bleeding or stress ulcer and should be reported. The pH and PaCO2 are slightly abnormal, but current guidelines advocating for permissive hypercapnia indicate that these would not indicate an immediate need for a change in therapy. The BUN is slightly elevated but does not indicate an immediate need for action. Adventitious breath sounds are commonly heard in patients with ARDS. DIF: Cognitive Level: Analyze (analysis) REF: 1623
When prone positioning is used for a patient with acute respiratory distress syndrome (ARDS), which information obtained by the nurse indicates that the positioning is effective? a. The patient's PaO2 is 89 mm Hg, and the SaO2 is 91%. b. Endotracheal suctioning results in clear mucous return. c. Sputum and blood cultures show no growth after 48 hours. d. The skin on the patient's back is intact and without redness.
ANS: A The purpose of prone positioning is to improve the patient's oxygenation as indicated by the PaO2 and SaO2. The other information will be collected but does not indicate whether prone positioning has been effective. DIF: Cognitive Level: Apply (application) REF: 1625 PaO2 normal: 75-100 mmHg SaO2 normal: 94-100%
A patient admitted with acute respiratory failure has ineffective airway clearance related to thick secretions. Which nursing intervention would specifically address this patient problem? a. Encourage use of the incentive spirometer. b. Offer the patient fluids at frequent intervals. c. Teach the patient the importance of ambulation. d. Titrate oxygen level to keep O2 saturation above 93%.
ANS: B Because the reason for the poor airway clearance is the thick secretions, the best action will be to encourage the patient to improve oral fluid intake. Patients should be instructed to use the incentive spirometer on a regular basis (e.g., every hour) to facilitate the clearance of the secretions. The other actions may also be helpful in improving the patient's gas exchange, but they do not address the thick secretions that are causing the poor airway clearance. DIF: Cognitive Level: Apply (application) REF: 1617
Which statement by the nurse when explaining the purpose of positive end-expiratory pressure (PEEP) to the patient's caregiver is accurate? a. "PEEP will push more air into the lungs during inhalation." b. "PEEP prevents the lung air sacs from collapsing during exhalation." c. "PEEP will prevent lung damage while the patient is on the ventilator." d. "PEEP allows the breathing machine to deliver 100% O2 to the lungs."
ANS: B By preventing alveolar collapse during expiration, PEEP improves gas exchange and oxygenation. PEEP will not prevent lung damage (e.g., fibrotic changes that occur with ARDS), push more air into the lungs, or change the fraction of inspired oxygen (FIO2) delivered to the patient. DIF: Cognitive Level: Understand (comprehension) REF: 1624
While caring for a patient who has been admitted with a pulmonary embolism, the nurse notes a change in the patient's oxygen saturation (SpO2) from 94% to 88%. Which action should the nurse take? a. Suction the patient's oropharynx. b. Increase the prescribed O2 flow rate. c. Instruct the patient to cough and deep breathe. d. Help the patient to sit in a more upright position.
ANS: B Increasing O2 flow rate will usually improve O2 saturation in patients with ventilation-perfusion mismatch, as occurs with pulmonary embolism. Because the problem is with perfusion, actions that improve ventilation, such as deep breathing and coughing, sitting upright, and suctioning, are not likely to improve oxygenation.
A patient with respiratory failure has a respiratory rate of 6 breaths/min and an oxygen saturation (SpO2) of 88%. The patient is increasingly lethargic. Which intervention will the nurse anticipate? a. Administration of 100% O2 by non-rebreather mask b. Endotracheal intubation and positive pressure ventilation c. Insertion of a mini-tracheostomy with frequent suctioning d. Initiation of continuous positive pressure ventilation (CPAP)
ANS: B The patient's lethargy, low respiratory rate, and SpO2 indicate the need for mechanical ventilation with ventilator-controlled respiratory rate. Giving high-flow O2 will not be helpful because the patient's respiratory rate is so low. Insertion of a mini-tracheostomy will facilitate removal of secretions, but it will not improve the patient's respiratory rate or oxygenation. CPAP requires that the patient initiate an adequate respiratory rate to allow adequate gas exchange.
A nurse is caring for a patient with ARDS who is being treated with mechanical ventilation and high levels of positive end-expiratory pressure (PEEP). Which assessment finding by the nurse indicates that the PEEP may need to be reduced? a. The patient's PaO2 is 50 mm Hg and the SaO2 is 88%. b. The patient has subcutaneous emphysema on the upper thorax. c. The patient has bronchial breath sounds in both the lung fields. d. The patient has a first-degree atrioventricular heart block with a rate of 58 beats/min.
ANS: B The subcutaneous emphysema indicates barotrauma caused by positive pressure ventilation and PEEP. Bradycardia, hypoxemia, and bronchial breath sounds are all concerns and will need to be addressed, but they are not specific indications that PEEP should be reduced. DIF: Cognitive Level: Apply (application) REF: 1623
Which actions should the nurse start to reduce the risk for ventilator-associated pneumonia (VAP) (select all that apply)? a. Obtain arterial blood gases daily. b. Provide a "sedation holiday" daily. c. Give prescribed pantoprazole (Protonix). d. Elevate the head of the bed to at least 30°. e. Provide oral care with chlorhexidine (0.12%) solution daily.
ANS: B, C, D, E All of these interventions are part of the ventilator bundle that is recommended to prevent VAP. Arterial blood gases may be done daily but are not always necessary and do not help prevent VAP .DIF: Cognitive Level: Apply (application) REF: 1623
During change-of-shift report on a medical unit, the nurse learns that a patient with aspiration pneumonia who was admitted with respiratory distress has become increasingly agitated. Which action should the nurse take first? a. Give the prescribed PRN sedative drug. b. Offer reassurance and reorient the patient. c. Use pulse oximetry to check the oxygen saturation. d. Notify the health care provider about the patient's status.
ANS: C Agitation may be an early indicator of hypoxemia. The other actions may also be appropriate, depending on the findings about O2 saturation. DIF: Cognitive Level: Analyze (analysis) REF: 1610
Which diagnostic test will provide the nurse with the most specific information to evaluate the effectiveness of interventions for a patient with ventilatory failure? a. Chest x-ray b. O2 saturation c. Arterial blood gas analysis d. Central venous pressure monitoring
ANS: C Arterial blood gas (ABG) analysis is most useful in this setting because ventilatory failure causes problems with CO2 retention, and ABGs provide information about the PaCO2 and pH. The other tests may also be done to help in assessing oxygenation or determining the cause of the patient's ventilatory failure.
The nurse assesses vital signs for a patient admitted 2 days ago with gram-negative sepsis: temperature of 101.2° F, blood pressure of 90/56 mm Hg, pulse of 92 beats/min, and respirations of 34 breaths/min. Which action should the nurse take next? a. Give the scheduled IV antibiotic. b. Give the PRN acetaminophen (Tylenol). c. Obtain oxygen saturation using pulse oximetry. d. Notify the health care provider of the patient's vital signs.
ANS: C The patient's increased respiratory rate in combination with the admission diagnosis of gram-negative sepsis indicates that acute respiratory distress syndrome (ARDS) may be developing. The nurse should check for hypoxemia, a hallmark of ARDS. The health care provider should be notified after further assessment of the patient. Giving the scheduled antibiotic and the PRN acetaminophen will also be done, but they are not the highest priority for a patient who may be developing ARDS. DIF: Cognitive Level: Analyze (analysis) REF: 1620
A patient with acute respiratory distress syndrome (ARDS) who is intubated and receiving mechanical ventilation develops a right pneumothorax. Which collaborative action will the nurse anticipate next? a. Increase the tidal volume and respiratory rate. b. Decrease the fraction of inspired oxygen (FIO2). c. Perform endotracheal suctioning more frequently. d. Lower the positive end-expiratory pressure (PEEP).
ANS: D Because barotrauma is associated with high airway pressures, the level of PEEP should be decreased. The other actions will not decrease the risk for another pneumothorax. DIF: Cognitive Level: Apply (application) REF: 1624
Which nursing interventions included in the care of a mechanically ventilated patient with acute respiratory failure can the registered nurse (RN) delegate to an experienced licensed practical/vocational nurse (LPN/LVN) working in the intensive care unit? a. Assess breath sounds every hour. b. Monitor central venous pressures. c. Place patient in the prone position. d. Insert an indwelling urinary catheter.
ANS: D Insertion of indwelling urinary catheters is included in LPN/LVN education and scope of practice and can be safely delegated to an LPN/LVN who is experienced in caring for critically ill patients. Placing a patient who is on a ventilator in the prone position requires multiple staff, and should be supervised by an RN. Assessment of breath sounds and obtaining central venous pressures require advanced assessment skills and should be done by the RN caring for a critically ill patient. DIF: Cognitive Level: Apply (application) REF: 1615
A patient develops increasing dyspnea and hypoxemia 2 days after heart surgery. To determine whether the patient has acute respiratory distress syndrome (ARDS) or pulmonary edema caused by heart failure, the nurse will plan to assist with a. obtaining a ventilation-perfusion scan. b. drawing blood for arterial blood gases. c. positioning the patient for a chest x-ray. d. insertion of a pulmonary artery catheter.
ANS: D Pulmonary artery wedge pressures are normal in the patient with ARDS because the fluid in the alveoli is caused by increased permeability of the alveolar-capillary membrane rather than by the backup of fluid from the lungs (as occurs in cardiogenic pulmonary edema). The other tests will not help in differentiating cardiogenic from noncardiogenic pulmonary edema. DIF: Cognitive Level: Apply (application) REF: 1625
After receiving change-of-shift report on a medical unit, which patient should the nurse assess first? a. A patient with cystic fibrosis who has thick, green-colored sputum b. A patient with pneumonia who has crackles bilaterally in the lung bases c. A patient with emphysema who has an oxygen saturation of 90% to 92% d. A patient with septicemia who has intercostal and suprasternal retractions
ANS: D This patient's history of septicemia and labored breathing suggest the onset of ARDS, which will require rapid interventions such as administration of O2 and use of positive-pressure ventilation. The other patients should also be assessed, but their assessment data are typical of their disease processes and do not suggest deterioration in their status. DIF: Cognitive Level: Analyze (analysis) REF: 1622
A client diagnosed with acute respiratory distress syndrome (ARDS) is restless and has a low oxygen saturation level. If the client's condition does not improve and the oxygen saturation level continues to decrease, what procedure will the nurse expect to assist with in order to help the client breathe more easily? A. Intubate the client and control breathing with mechanical ventilation B. Increase oxygen administration C. Administer a large dose of furosemide (Lasix) IVP stat D. Schedule the client for pulmonary surgery
Answer Key:A Rationale: A client with ARDS may need mechanical ventilation to assist with breathing while the underlying cause of the pulmonary edema is corrected. The other options are not appropriate.
A nurse assesses arterial blood gas results for a patient in acute respiratory failure (ARF). Which results are consistent with this disorder? A. pH 7.28, PaO2 50 mm Hg B. pH 7.46, PaO2 80 mm Hg C. pH 7.36, PaCO2 32 mm Hg D. pH 7.35, PaCO2 48 mm Hg
Answer Key:A Rationale: ARF is defined as a decrease in arterial oxygen tension (PaO2) to less than 60 mm Hg (hypoxemia) and an increase in arterial carbon dioxide tension (PaCO2) to >50 mm Hg (hypercapnia), with an arterial pH less than 7.35.
A child is brought to the emergency department late one evening and is diagnosed with croup. The child was noted to have a shrill, harsh respiratory sound when breathing in. This symptom is referred to as: A. stridor. B. hoarseness. C. barking cough. D. wheezing.
Answer Key:A Rationale: In the child with croup syndrome, inspiratory stridor (shrill, harsh respiratory sound) is often noted.
The nurse is assessing a client who, after an extensive surgical procedure, is at risk for developing acute respiratory distress syndrome (ARDS). The nurse assesses for which most common early sign of ARDS? A. Rapid onset of severe dyspnea B. Inspiratory crackles C. Bilateral wheezing D. Cyanosis
Answer Key:A Rationale: The acute phase of ARDS is marked by a rapid onset of severe dyspnea that usually occurs less than 72 hours after the precipitating event.
The nurse is auscultating the patient's lung sounds to determine the presence of pulmonary edema. What adventitious lung sounds are significant for pulmonary edema? A. Crackles in the lung bases B. Low-pitched rhonchi during expiration C. Pleural friction rub D. Sibilant wheezes
Answer Key:A Rationale: When clinically significant atelectasis develops, it is generally characterized by increased work of breathing and hypoxemia. Decreased breath sounds and crackles are heard over the affected area.
A client who sustained a pulmonary contusion in a motor vehicle crash develops a pulmonary embolism. What is the priority nursing concern with this client? A. Acute pain B. Ineffective breathing pattern C. Activity intolerance D. Excess fluid volume
Answer Key:B Rationale: Ineffective breathing pattern takes priority for a client with a pulmonary contusion with a pulmonary embolism. The objective of immediate management is to restore and maintain cardiopulmonary function. After an adequate airway is ensured and ventilation is established, examination for shock and intrathoracic and intra-abdominal injuries is necessary. Fluid volume, pain, and activity intolerance are not priority concerns.
A client is receiving thrombolytic therapy for the treatment of pulmonary emboli. What is the best way for the nurse to assess the client's oxygenation status at the bedside? A. Obtain serial ABG samples B. Monitor pulse oximetry readings C. Perform chest auscultation D. Monitor incentive spirometry volumes
Answer Key:B Rationale: The nurse assesses the client 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 client hospitalized with pneumonia has thick, tenacious secretions. Which intervention should the nurse include when planning this client's care? A. Turning the client every 2 hours B. Elevating the head of the bed 30 degrees C. Encouraging increased fluid intake D. Maintaining a cool room temperature
Answer Key:C Rationale: Increasing the client's intake of oral or I.V. fluids helps liquefy thick, tenacious secretions, and ensures adequate hydration. Turning the client every 2 hours would help prevent atelectasis, but will not adequately mobilize thick secretions. Elevating the head of the bed would reduce pressure on the diaphragm and ease breathing, but wouldn't help the client with secretions. Maintaining a cool room temperature wouldn't help the client with secretions.
The nurse is interpreting blood gases for a client with acute respiratory distress syndrome (ARDS). Which set of blood gas values indicates respiratory acidosis? A. pH 7.87, PaCO2 38, HCO3 28 B. pH 7.47, PaCO2 28, HCO3 30 C. pH 7.49, PaCO2 34, HCO3 25 D. pH 7.25, PaCO2 48, HCO3 24
Answer Key:D Rationale: pH<7.35, PaCO2 48, HCO3 24 indicate respiratory acidosis; pH 7.87, PaCO2 38, HCO3 28 indicate metabolic alkalosis; pH 7.47, PaCO2 28, HCO3 30 indicate respiratory alkalosis; pH 7.49, PaCO2 34, HCO3 25 indicate respiratory alkalosis.
The nurse has assessed a 6-year-old child as having respiratory distress due to swelling of the epiglottis and surrounding structures. Which signs and symptoms would support this assessment? A. The child is pale and has vomited. B. The child has pale, elevated patches on the skin. C. The child is irritable and tachycardiac. D. The child is in tripod position.
Answer Key:D Rationale: Inflammation and swelling of the epiglottis and surrounding structures are common in children ages 2 to 7 years. The child will attempt to improve his/her airway by sitting forward and extending the neck forward with the jaw up, in a "sniffing position" (tripod position). Being pale, vomiting, and having elevated patches on the skin are not associated with epiglottis. Stridor, tachycardia, and the rapid onset are classical signs of epiglottitis.

Pulmonary embolism overview
The mortality of diagnosed and treated PE is 7%. Many more people die from undiagnosed PE. Most patients present with dyspnea +/- chest pain. The main risk factors is the development of DVT from immobility; surgery, pregnancy, chronic disease, increasing age. There are two forms of imaging for PE: CT pulmonary angiography and V/Q scanning. Other investigations include bloods taking a d-dimer test. General treatment includes IV heparin followed by oral warfarin therapy. For massive (serious) PE thrombolytic therapy is initiated.
