4 | Page D. DDD 44. You know that a demand pacing mode means the following except: A. Delivers a pacing stimulus at a set rate B. Delivers a pacing stimulus only when the heart’s intrinsic pacemaker fails C. A predetermined rate is set D. Pacing stimulus activity is determined by the sensing of intrinsic activity 45. You are modifying your patient’s pacemaker settings and have to determine the threshold of the device. Everything is true about thresholds of pacemakers except? A. Depolarization occurs at this point B. Determining the threshold involves losing the 1:1 capture C. The threshold to pace is less than 1 mA D. This is the ability of the pacemaker to detect the heart’s intrinsic electrical activity 46. Your patient is on mechanical ventilation. The machine is there to assist the patient with breathing. As a nurse, you are familiar with the anatomy and physiology of the lung. Which is true about the effects of gravity and alveolar pressure on pulmonary blood flow? (Pa = arterial pressure; PA = alveolar pressure) A. Zone 1 involves Pa>PA B. Zone 3 involves Pa>PA C. Zone 1 is where blood flow occurs in the lungs D. Zone 2 has fluctuating blood flow dependent on arterial and venous pressures 47. Your patient is being monitored with a capnography at the bedside. You notice that the PETCO2 is increased. The following can be possible causes for this except? A. Respiratory depression B. Hyperthermia C. Sepsis D. Hypothermia 48. A patient is on mechanical ventilation. As a nurse, you are expected to understand and know how to manipulate mechanical ventilators. Which variables maintains inspiration? A. Trigger B. Cycle C. Limit D. Baseline 49. Which of the following variables ends the inspiration? A. Trigger B. Cycle C. Limit D. Baseline 50. Your patient has a stable respiratory drive to overcome any imposed mechanical resistance. He is able to have spontaneous breaths but it is not yet enough to provide his body with adequate oxygenation. What mode of ventilation is the most appropriate for this patient? A. Volume-assured pressure support ventilation B. Airway pressure release ventilation C. Adaptive support ventilation D. Pressure support ventilation 51. Your patient is in acute respiratory distress and was placed on mechanical ventilation. You except the tidal volume to be set with the following: A. 6-10 mL/kg B. 4-8 mL/kg C. 7-10 mL/kg D. 4-6 mL/kg 52. You need to set the amount of effort the patient must generate to initiate a ventilator breath. This can be done through pressure-triggering or flow-triggering. What parameter will you have to control to achieve this? A. Sensitivity B. High pressure limit C. Pressure support D. PEEP 53. Your patient is no longer in acute respiratory distress and is being considered for weaning from mechanical ventilation. Obtaining his rapid shallow breathing index (RSBI) will give you an idea of weaning success. The patient’s respiratory rate is 30 breaths per minute, and his weight is 50 kg. If his tidal volume is set at 7 mL/kg, calculate his RSBI: A. 88 breaths/min/L B. 86 breaths/min/L C. 12 breaths/min/L D. 13 breaths/min/L 54. You can interpret the previously calculated RSBI as? A. Successful weaning B. Unsuccessful weaning C. Inconclusive D. Monitor more before weaning 55. Your RSBI is calculated at 104. The patient’s conventional weaning parameters were obtained and they are within weanable values. What is the next step? A. Recommend removing the patient from mechanical ventilation B. Prepare the equipment for extubation C. Perform a spontaneous breathing trial D. Nothing 56. Which of the following weaning methods can you consider for your patient? A. Pressure support ventilation B. Continuous mandatory ventilation C. Adaptive support ventilation D. Independent lung ventilation 57. When the patient was undergoing weaning, you noticed that his spontaneous tidal volume was at 350 mL, with a heart rate of 100. His SPO2 is also found to be 91%. What action should you take next? A. Stop weaning because the patient is unable to tolerate this B. Continue weaning due to no indication of weaning intolerance C. Increase the patient’s FiO2 D. Position the patient in an upright position Situation – Nurse Lexi is caring for multiple patients with respiratory problems in the emergency department of Lorenzo General Hospital. The following questions apply. 58. While inspecting the chest of a client, she assessed that the anteroposterior diameter is exactly the same as the lateral diameter. This implies that the client has:* A. Pigeon chest B. Normal chest C. Barrel chest D. Pectus excavatum 59. Nurse Lexi assessed that the patient has tracheal shifting to the right. The following respiratory conditions are possible causes of the tracheal deviation except: A. Pleural effusion of the left lung field B. Empyema thoracis of the right lung field C. Atelectasis of the right lung field D. Pleural fibrosis of the right lung field   60. One of the physical characteristic of blood is its temperature being
