Chapter 15: Acute Respiratory Failure

The nurse is caring for a patient with a diagnosis of pulmonary embolism. The nurse understands that the most common cause of a pulmonary embolus is: a. amniotic fluid embolus. b. deep vein thrombosis from lower extremities. c. fat embolus from a long bone fracture. d. vegetation that dislodges from an infected central venous catheter.

b.

Which of the following are components of the Institute for Healthcare Improvement's (IHI's) ventilator bundle? (Select all that apply.) a. Interrupt sedation each day to assess readiness to extubate. b. Maintain head of bed at least 30 degrees elevation. c. Provide deep vein thrombosis prophylaxis. d. Provide prophylaxis for peptic ulcer disease. e. Swab the mouth with foam swabs every 2 hours.

a, b, c, d

Select the strategies for preventing deep vein thrombosis (DVT) and pulmonary embolus (PE). (Select all that apply.) a. Graduated compression stockings b. Heparin or low-molecular weight heparin for patients at risk c. Sequential compression devices d. Strict bed rest

a,b,c

The nurse is caring for a mechanically ventilated patient. The nurse understands that strategies to prevent ventilator-associated pneumonia include which of the following? (Select all that apply.) a. Drain condensate from the ventilator tubing away from the patient. b. Elevate the head of the bed 30 to 45 degrees. c. Instill normal saline as part of the suctioning procedure. d. Perform regular oral care with chlorhexidine.

a,b,d

Which of the following statements is true regarding venous thromboembolism (VTE) and pulmonary embolus (PE)? a. PE should be suspected in any patient who has unexplained cardiorespiratory complaints and risk factors for VTE. b. Bradycardia and hyperventilation are classic symptoms of PE. c. Dyspnea, chest pain, and hemoptysis occur in nearly all patients with PE. d. Most critically ill patients are at low risk for VTE and PE and do not require prophylaxis.

a.

Which of the following statements is true regarding oral care for the prevention of ventilator-associated pneumonia (VAP)? (Select all that apply.) a. Tooth brushing is performed every 2 hours for the greatest effect. b. Implementing a comprehensive oral care program is an intervention for preventing VAP. c. Oral care protocols should include oral suctioning and brushing teeth. d. Protocols that include chlorhexidine gluconate have been effective in preventing VAP.

b, c, d

A patient at high risk for pulmonary embolism is receiving Lovenox. The nurse explains to the patient: a. "I'm going to contact the pharmacist to see if you can take this medication by mouth." b. "This injection is being given to prevent blood clots from forming." c. "This medication will dissolve any blood clots you might get." d. "You should not be receiving this medication. I will contact the physician to get it stopped."

b.

The nurse is discharging a patient home following treatment for community-acquired pneumonia. As part of the discharge teaching, the nurse instructs: a. "If you get the pneumococcal vaccine, you'll never get pneumonia again." b. "It is important for you to get an annual influenza shot to reduce your risk of pneumonia." c. "Stay away from cold, drafty places because that increases your risk of pneumonia when you get home." d. "Since you have been treated for pneumonia, you now have immunity from getting it in the future."

b.

A definitive diagnosis of pulmonary embolism can be made by: a. arterial blood gas (ABG) analysis. b. chest x-ray examination. c. pulmonary angiogram. d. ventilation-perfusion scanning.

c.

A patient presents to the emergency department in acute respiratory failure secondary to community-acquired pneumonia. The patient has a history of chronic obstructive pulmonary disease. The nurse anticipates which treatment to facilitate ventilation? a. Emergency tracheostomy and mechanical ventilation b. Mechanical ventilation via an endotracheal tube c. Noninvasive positive-pressure ventilation (NPPV) d. Oxygen at 100% via bag-valve-mask device

c.

The nurse is caring for a patient with acute respiratory failure and identifies "Risk for Ineffective Airway Clearance" as a nursing diagnosis. A nursing intervention relevant to this diagnosis is: a. Elevate head of bed to 30 degrees. b. Obtain order for venous thromboembolism prophylaxis. c. Provide adequate sedation. d. Reposition patient every 2 hours.

d.

The nurse is concerned that a patient is at increased risk of developing a pulmonary embolus and develops a plan of care for prevention to include which of the following? a. Antiseptic oral care b. Bed rest with head of bed elevated c. Coughing and deep breathing d. Mobility

d.

Which of the following treatments may be used to dissolve a thrombus that is lodged in the pulmonary artery? a. Aspirin b. Embolectomy c. Heparin d. Thrombolytics

d.
