RRT TMC Exam Questions And Answers 100% Verified The patient's lung has an air leak - answerYou are called to the emergency department to help care for a patient who was in a vehicle accident and has chest injuries including broken ribs. Crepitations are felt while palpitating the patient's neck. What is most likely the cause of this? Reversible airway obstruction - answerA forced expiratory measurement obtained after the administration of a bronchodilator shows an increase in FEV1 from 60% to 80% of predicted. This indicates a: complete airway obstruction - answerDuring capnography monitoring of a mechanically ventilated patient, you note that the end-tidal PCO2 (PetCO2) has dropped to 0 mm Hg. This finding may indicate: inserting an esophageal-tracheal combitube - answerAn unconscious apneic patient with a full stomach cannot be orally intubated in the emergency room. Which of the following would your recommend be? patients size and clinical condition - answerWhile establishing initial ventilatory support settings for a new patient, the most important consideration is the: Fever (hyperthermia) - answerA male patient has a lower than normal mixed venous O2 content. Which of the following is the most likely cause of this condition? apply 5-10 cm H20 pressure support - answerYou are trying to wean an alert intubated patient off full ventilatory support using the CPAP protocol with 40% O2. Early in the initial effort her respiratory rate increases from 24 to 30/min and you start to observe some use of her accessory muscles while breathing. Which of the following would be your first action at this time? 70 minutes - answerWhat is the approximate duration of flow of an oxygen E-cylinder at 1000 psi running at 4 L/min? increase the suction pressure to -120 mm Hg - answerWhile using a Yankauer device to suction an adult patient, you are unable to remove thick secretions. The regulator attached to the oropharyngeal suctioning device displays a reading of -70 mm Hg. Which of the following actions should you take at this time? a missing lead - answerWhile setting up a 12-lead EKG on a patient, you are unable obtain any electrical signal. The batteries are fully charged and the device was able to power-on. The most likely cause of this problem is which of the following? angiography - answerWhich of the following imaging procedures is used to evaluate the arteries for abnormalities such as aneurysm, atherosclerosis, embolism, occlusion, stenosis, thrombosis, trauma, or vasculitis? has smoked within the prior 12-24 hours - answerYou obtain an expired carbon monoxide (CO) reading of 18 ppm on a COPD patient participating in a pulmonary rehabilitation program. Based on this finding, you can conclude that the patient: decrease in O2 saturation from 91% to 82% - answerWhile monitoring a patient during a spontaneous breathing trial, which of the following observations would cause you to stop the trial and return the patient to ventilatory support? increased ventilation - answerYour patient is receiving volume control A/C ventilation. She has become increasingly agitated and the end-tidal CO2 has decreased from 38 to 27 torr over the last 3 hours. Which of the following is most likely the cause? 3500 mL - answerA normal vital capacity for a female patient who is five feet three inches tall and weighs fifty kilograms would be approximately: the sensitivity - answerAn asthmatic patient is struggling to initiate inspiration on a ventilator operating in the assist-control mode. Which of the following ventilator settings would you first check in order to resolve of this problem? atrial fibrillation - answerOn inspection of a patient's EKG strip, you note that there are no identifiable P waves; rapid irregular undulations of the isoelectric line; and an irregular ventricular rhythm. In addition, the precordial cardiac rate is greater than the peripheral pulse rate. What is the most likely problem? Vital Capacity (VC) - answerWhich of the following is the best bedside measurement for assessing the integrated function of the respiratory muscles and mechanical properties of the lungs and thorax? Sinus Tachycardia - answerWhile inspecting an EKG rhythm strip from an adult patient, you note the following: rate of 148; regular rhythm; normal P waves, P-R intervals, and QRS complexes. What is most likely the problem? whether the patient is stable on low FiO2s and PEEP - answerWhich of the following is a prerequisite for discharging a ventilator-dependent patient to the homecare setting? a large volume (3 L) calibration syringe - answerYou would need which of the following equipment in order to calibrate a portable bedside spirometer? Ventilator-associated pneumonia (VAP) - answerA physician orders a blind bronchoalveolar lavage procedure for a patient in intensive care unit. What is the most likely potential diagnosis that the doctor is trying to confirm with this procedure? croup - answerAn AP X-ray of a 4-year-old child with wheezing and stridor shows an area of prominent subglottic edema, but the lateral neck X-ray appears normal. The most likely problem is? sternocleidomastoid muscles used at rest - answerIf noted on inspiration, which of the following respiratory signs of an adult patient would be considered abnormal? between the 2nd and 4th thoracic vertebra - answerWhile reviewing the chest X-ray of a 30-year-old male receiving ventilatory support via an oral endotracheal tube. To assure proper placement of the tube, you would look for its tip to be positioned pulseless ventricular tachycardia - answerDefibrillation should be done immediately in which of the following patient situations? variable flow control and adjustable I:E ratios - answerAn intubated adult 65-year-old male patient with severe expiratory airway obstruction requires ventilatory support. Which of the following capabilities would be most important in selecting a ventilator for this patient? the patient cannot sustain prolonged spontaneous ventilation - answerYou are called to obtain a bedside vital capacity (VC) of 450 ml on a 122 lb female patient receiving ventilatory support in the CMV mode. Which of the following can you draw from this finding? hyperventilation/hypocapnia - answerWhich of the following is the most common problem encountered when applying assist-control mode during ventilation? flowmeter-humidifier connection for leaks - answerA bubble humidifier is not bubbling during oxygen therapy, despite the flowmeter set and running at 5 L/min. Which of the following should you check? bronchospasm - answerWhich of the following would cause an increase in a patient's peak airway pressure while receiving volume control ventilation? inspissated secretions - answerAfter review a patient's chart, you note that an admission diagnosis of fluid depletion/dehydration. Which of the following findings would be most likely on bedside assessment of this patient? it would underestimate the CVP - answerYou are called to help a nurse in ICU measure a patient's central venous pressure (CVP) with a strain-gauge pressure transducer. The pressure transducer appears to be positioned well above the middle of the patient's lateral chest wall. What effect if any would this have on the measurement?
