TMC exam form B
| Question | Answer |
|---|---|
| A patient with bronchiectasis who uses postural drainage at home has had three recent exacerbation requiring hospitalization. What should the RT recommend? | -HFCWO provides a effective method to loosen and mobilize secretions. |
| A RT is assisting with a tracheostomy for a patient on PC ventilation. Following placement of the tube, the therapist observes increased heart rate, decreasing exhaled tidal volume, and increasingly distant breath sounds over the right chest. | -pneumothorax will result in tachycardia, decreased ventilation, and decreased breath sounds on the affected side. |
| What is an indication for a placement of an oropharyngeal airway? | -prevention of upper airway obstruction in an unconscious patient |
| A patient is intubated with a tidal volume of 600mL. The patients pH was normal, the patient was switched to A/C ventilation at the same rate. Exhaled tidal volume is averaging 750mL. The patient is at risk for? | -Alkalosis due to the increased tidal volume and minute ventilation |
| Which of the following may be caused by the administration of aerosolized pentamidine isethionate (NebuPent)? | -Bronchospasm |
| A fixed wing medical transport with an unpressurized cabin has ascended to 10,000 ft. while transporting a patient with COPD. The patient is receiving nasal oxygen at 2L/min and becomes agitated and confused. A respiratory therapist should? | -Increase the oxygen flow, the patient is experiencing hypoxemia associated with altitude and a lower inspired PaO2. Increasing the O2 flow with increase the inspired FiO2. |
| A pt. w/ COPD is on PC ventilation with flow triggering and has significant air trapping displayed on the ventilator graphics. The patients spontaneous breathing efforts are not always detected by the ventilator. What change will improve sychrony? | -Increase the peep for significant air trapping and dyssynchrony |
| When calibrating a fuel cell oxygen analyzer, the analyzer should be set to? | -21% while exposed to room air |
| A 4 year old child is seen for a follow up asthma visit. No dyspnea present, however he is using his albuterol inhaler twice daily. What do you recommend? | -explain the purpose of the quick relief medication |
| A pt. with COPD and pneumonia is receiving VC,SIMV. FiO2-0.28, R 8, total rate 16, VT 700mL, Sp. Vt 425mL, PS 5, PEEP 4. ABG: 7.33, 54(high), 78, 28 | -initiate a spontaneous breathing trial, these are within normal limits for a COPD patient. |
| What is the amount of air that can be maximally exhaled from maximum inspira ion? | -Vital CapacityA |
| A pt. receiving mechanical ventilation had a total fluid intake of 4200mL and a total fluid output of 1200mL over a 24-hour period. What will increase in this situation? | -P(A-a)O2 |
| Furosemide (Lasix) and oxygen therapy re initiated for a pt. with pulmonary edema, Which of the following should a RT recommend? | -Pulse oximetry and monitoring of electrolyte levels |
| An adult pt. is receiving beta blocker medication and requires bronchodilator therapy. What medicine do you recommend? | -Ipratropium bromide (atrovent) is an anticholinergic and beta blockers don't affect it's ability to achieve bronchodilation. |
| IBW formula female (45.5kg + 2.3(inches over 5") Pt. is 5"2 (45.5 + 2.3(2) = 50 50(6)=300 50(10)=500 Vt Range 300-500mL | |
| While administering an IPPB tx a RT notes the system pressure fails to rise during inspiration and the patient has difficulty keeping her lips around the mouthpiece. What do you recommend? | -Use a mask |
| What is the major component of pulmonary surfactant? | -Phospholipid |
| During mechanical ventilation, MAP will always change with a change in? | -inspiratory time, lengthening the inspiratory time allows the ventilator to increase the tidal volume and the MAP |
| What values are needed to determine a patients physiologic deadspace? | -Arterial PCO2 and mixed expired PCO2 Vd/Vt=(PaCo2-PeCo2)/Paco2 |
| What is the static compliance? Cs= VT/PpL -PEEP Exhaled Vt- 500mL PpL- 15 PEEP 5 | Cs= 500/15-5= 50 |
| Which of the following factors will influence the oxygen concentration delivered to a self inflating manual resuscitator? | -Oxygen flow and reservoir size. |
| Which of the following should a RT recommend for a patient who is receiving mechanical ventilator support and has moderate muscuskeletal pain? | -Fentanyl citrate is an analgesic agent and will be helpful to reduce muscoskeletal pain. |
| What assessments can be made from a pressure volume loop? | -Presence of inspiratory work -pulmonary compliance -spontaneous tidal volume Not: amount of air trapping |
| a male is admitted to the ICU following a drug OD. VC/A/C ventilation is initiated: the high pressure alarm is sounding with wide fluctuations in pressure. | -increase the flow |
| when measuring vital capacity, a RT should instruct a patient to inhale. | -maximally and exhale maximally |
| while reviewing a medical record, a RT notes a pt. has SOB, pleuritic chest pain, tachypnea, and tachycardia, and a swollen and tender right leg. what do these findings indicate? | -Pulmonary Embolism |
| a pt. with muscular dystrophy is seen in the ED following a 2 day history of increasing SOB. ABG shows: 7.31, 65,58,33 what should you recommend? |
