Document Content and Description Below

A patient in the hospital is recovering from hip surgery. She begins to complain of chest pain and dyspnea. Her RR is 30. 1. A lung scan is performed and the V/Q ratio is reported to the nurse as �... �high.” This patient has most likely suffered a(n) a. MI. b. pulmonary embolus. c. atelectasis. d. episode of pulmonary edemaArterial blood gases (ABGs) are drawn. The results are: pH: 7.50; PO2: 100; PCO2: 29; HCO3: 26. This altered state is called a. respiratory acidosis b. metabolic acidosis c. respiratory alkalosis. d. metabolic alkalosisWhat mechanism is likely causing the disturbance noted in question #2? a. Hypoventilation b. Hyperventilation c. Hemoptysis. d. Orthopnea.The nurse taking care of a pulmonary patient notes that he is very thin and barrel-chested, has a respiratory rate of 28, and uses accessory muscles to breathe. 7. The nurse thinks it is most likely that the patient’s S&S are due to a. chronic bronchitis. b. a VQ ratio. c. emphysema. d. Kussmaul respirationsAn arterial blood gas report shows pH = 7.50, PCO2 = 32, PO2= 90, SO2= 92% HCO3 = 26. These numbers mean the patient a. is in metabolic alkalosis. b. has hypercapnia, which is his normal state of compensation. c. is probably in respiratory failure. d. is probably in his normal state of compensatory hyperventilation.A 50 year old male is evaluated in the emergency room (ER) for a complaint of dyspnea. The dyspnea has become worse over many years but today is especially bad. He reports a history of smoking. His breath sounds are clear but greatly diminished throughout his lungs. ABGs, peak flow test (PF), VQ scan and chest x-ray (CXR) are completed. Results are below. ABGs: pH 7.48, PCO2: 30, HCO3 : 24, PO2 80, SO2 94%. PF: 50% of predicted norm (ie, “low” PF). V/Q scan 0.8. CXR shows hyperinflated aveoli and air trapping [Show More]
