a, b, c, e, f

Which diagnostic test will provide the nurse with the most specific information to evaluatethe effectiveness of interventions for a patient with ventilatory failure?a. Chest x-rayb. O2 saturationc. Arterial blood gas analysisd. Central venous pressure monitoring

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.


A patient with respiratory failure has a respiratory rate of 6 breaths/min and an oxygensaturation (SpO2) of 88%. The patient is increasingly lethargic. Which intervention will thenurse anticipate?a. Administration of 100% O2 by non-rebreather maskb. Endotracheal intubation and positive pressure ventilationc. Insertion of a mini-tracheostomy with frequent suctioningd. Initiation of continuous positive pressure ventilation (CPAP)


A nurse is caring for an obese patient with right lower lobe pneumonia. Which position willbe best to improve gas exchange?a. On the left sideb. on the right sidec. in the tripod positiond. in the high fowler's position

aThe patient should be positioned with the "good" lung in the dependent position to improvethe match between ventilation and perfusion. The obese patient's abdomen will limitrespiratory excursion when sitting in the high-Fowler's or tripod positions

A patient develops increasing dyspnea and hypoxemia 2 days after heart surgery. Todetermine whether the patient has acute respiratory distress syndrome (ARDS) or pulmonaryedema caused by heart failure, the nurse will plan to assist witha. 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.

dpulmonary artery wedge pressures are normal in the patient with ARDS bc 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 with cardiogenic pulmonary edema)

A nurse is caring for a patient with ARDS who is being treated with mechanical ventilationand high levels of positive end-expiratory pressure (PEEP). Which assessment finding by thenurse 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.

bthe subQ 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

Which statement by the nurse when explaining the purpose of positive end-expiratorypressure (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.

bby preventing alveolar collapse during expiration, PEEP improves gas exchange and oxygenation. PEEP will not prevent lung damage, push more air into the lungs, or change the fraction of inspired oxygen delivered to the pt

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 includein 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.

aelevation of the head decreases the risk for aspiration.

A patient with acute respiratory distress syndrome (ARDS) who is intubated and receivingmechanical ventilation develops a right pneumothorax. Which collaborative action will thenurse 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).

dbecause barotrauma is associated with high airway pressure, the level of PEEP should be decreased The other actions will not decrease the risk for another pneumothorax

After receiving change-of-shift report on a medical unit, which patient should the nurse assessfirst?a. A patient with cystic fibrosis who has thick, green-colored sputumb. A patient with pneumonia who has crackles bilaterally in the lung basesc. A patient with emphysema who has an oxygen saturation of 90% to 92%d. A patient with septicemia who has intercostal and suprasternal retractions

D this patient's history of septicemia and labored breathing suggest the onset of ARDS, which will require rapid intervention such as administration of O2 and use of positive pressure ventilation.

The nurse is caring for an older patient who was hospitalized 2 days earlier withcommunity-acquired pneumonia. Which assessment information is most important tocommunicate to the health care provider?a. Persistent cough of blood-tinged sputum.b. Scattered crackles in the posterior lung bases.c. Oxygen saturation 90% on 100% O2 by nonrebreather mask.d. Temperature 101.5° F (38.6° C) after 2 days of IV antibiotics.

cthe pt's low SpO2 despite receiving a high fraction of inspired oxygen indicates the possibility of acute respiratory distress syndrome

nurse is caring for a patient with acute respiratory distress syndrome (ARDS) who isreceiving 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 assessmentfinding is most important for the nurse to report to the health care provider?a. O2 saturation of 99%b. HR 106 beats/minutec. crackles audible at lung basesd. respiratory rate 22 breaths/minute

athe FIO2 of 80% increases the risk for O2 toxicity. Because O2 sat is 99%, a decrease in FIO2 is indicated to avoid toxicity

The nurse is caring for a patient who is intubated and receiving positive pressure ventilation totreat acute respiratory distress syndrome (ARDS). Which finding is most important to reportto the health care provider?a. Red-brown drainage from nasogastric tubeb. Blood urea nitrogen (BUN) level 32 mg/dLc. Scattered coarse crackles heard throughout lungsd. Arterial blood gases: pH of 7.31, PaCO2 of 50, and PaO2 of 68

athe nasogastric drainage indicates possible GI bleeding or stress ulcer and should be reported.

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
