a
When fluid is present in the alveoli: a. alveoli collapse and atelectasis occurs. b. diffusion of oxygen and carbon dioxide is impaired. c. hypoventilation occurs. d. the patient is in heart failure.
B
The nurse assesses a patient who is admitted for an overdose of sedatives. The nurse expects to find which acid-base alteration? a. Hyperventilation and respiratory acidosis b. Hypoventilation and respiratory acidosis c. Hypoventilation and respiratory alkalosis d. Respiratory acidosis and normal oxygen levels
B
The basic underlying pathophysiology of acute respiratory distress syndrome results from: a. a decrease in the number of white blood cells available. b. damage to the right mainstem bronchus. c. damage to the type II pneumocytes, which produce surfactant. d. decreased capillary permeability.
C
The nurse is caring for a patient with acute respiratory distress syndrome who is hypoxemic despite mechanical ventilation. The physician orders a nontraditional ventilator mode as part of treatment. Despite sedation and analgesia, the patient remains restless and appears to be in discomfort. The nurse informs the physician of this assessment and anticipates an order for: a. continuous lateral rotation therapy. b. guided imagery. c. neuromuscular blockade. d. prone positioning.
C
Which of the following acid-base disturbances commonly occurs with the hyperventilation and impaired gas exchange seen in severe exacerbation of asthma? a. Metabolic acidosis b. Metabolic alkalosis c. Respiratory acidosis d. Respiratory alkalosis
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
assessing a patient, the nurse understands that an early sign of hypoxemia is: a. clubbing of nail beds b. cyanosis c. hypotension d. restlessness
D
During rounds, the physician alerts the team that proning is being considered for a patient with acute respiratory distress syndrome. The nurse understands that proning is: a. an optional treatment if the PaO2/FiO2 ratio is less 100. b. less of a risk for skin breakdown because the patient is face down. c. possible with minimal help from co-workers. d. used to provide continuous lateral rotational turnin
a
The nurse is caring for a patient who is being turned prone as part of treatment for acute respiratory distress syndrome. The nurse understands that the priority nursing concern for this patient is which of the following? a. Management and protection of the airway b. Prevention of gastric aspiration c. Prevention of skin breakdown and nerve damage d. Psychological support to patient and family
a
Which of the following are physiological effects of positive end-expiratory pressure (PEEP) used in the treatment of ARDS? (Select all that apply.) a. Increase functional residual capacity b. Prevent collapse of unstable alveoli c. Improve arterial oxygenation d. Open collapsed alveoli
a, b, c, d
dentify diagnostic criteria for ARDS. (Select all that apply.) a. Bilateral infiltrates on chest x-ray study b. Decreased cardiac output c. PaO2/ FiO2 ratio of less than 200 d. Pulmonary artery occlusion pressure (PAOP) of more than 18 mm Hg
a, c
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
The nurse calculates the PaO2/FiO2 ratio for the following values: PaO2 is 78 mm Hg; FiO2 is 0.6 (60%). a. 46.8; meets criteria for ARDS b. 130; meets criteria for ARDS c. 468; normal lung function d. Not enough data to compute the ratio
b
The nurse is assessing a patient with acute respiratory distress syndrome. An expected assessment is: a. cardiac output of 10 L/min and low systemic vascular resistance. b. PAOP of 10 mm Hg and PaO2 of 55. c. PAOP of 20 mm Hg and cardiac output of 3 L/min. d. PAOP of 5 mm Hg and high systemic vascular resistance.
b
The nurse is assessing a patient. Which assessment would cue the nurse to the potential of acute respiratory distress syndrome (ARDS)? a. Increased oxygen saturation via pulse oximetry b. Increased peak inspiratory pressure on the ventilator c. Normal chest radiograph with enlarged cardiac structures d. PaO2/FiO2 ratio > 300
