TMC MOCK EXAM Actual Questions & Verified Answers Correctly 1.Although treated with several antiarrhythmic drugs, a patient with ventricular tachycardia begins to exhibit hypotension and decreased consciousness. Which of the following actions would you recommend at this time?immediately initiate CPR apply cardioversion administer epinephrine

defibrillate the patient:

Answer apply cardioversion *If drug management fails, if the ventricular rate exceeds 150/min, or if the patient becomes hemodynamically unstable, synchronous cardioversion is indicated.

2.A physician orders intubation and volume-controlled A/C ventilation for a 6-foot, 3-inch tall 190-lb (86-kg) adult male patient with ARDS. Which of the following ventilator settings would you aim for to support this patient?rate/min: 10; VT (mL): 800 rate/min: 15; VT (mL): 500 1 / 4

2 / 78

rate/min: 20; VT (mL): 900 rate/min: 8; VT (mL): 1200: Answer rate/min: 15; VT (mL): 500 Tidal volume 6ml/kg IBW 6ft 3= 85kg IBW Vt= 500 Rate= 10 to 20 3.A doctor institutes volume-controlled ventilation for a 70-kg ARDS patient with a targeted tidal volume of 420 mL to maintain adequate ventilation with this tidal volume, the maximum respiratory rate you would

allow is:

25/min 35/min 20/min

30/min:

Answer 35/min 4.Which of the following PaCO2 levels would be considered a positive result for brain death determination at the end of an apnea test?-at least 50 mm Hg -at least 45 mm Hg -at least 60 mm Hg

-at least 55 mm Hg: 2 / 4

3 / 78

Answer at least 60 mm Hg or 20+ from baseline CO2 5.A COPD patient receiving volume-controlled A/C ventilation at a rate of 15 and a VT of 650 mL exhibits signs of air trapping (auto-PEEP). Which of the following alternatives would you recommend to help overcome this problem?

1.add an end-inspiratory pause 2.switch to SIMV and decrease the rate 3.increase the inspiratory flow

• and 3 only

1, 2, and 3

• and 3 only

1 and 2 only:

Answer 2 and 3 only

• Adding an end-inspiratory pause would cause more air-trapping

6.A patient who just underwent major thoracic surgery is placed on pres- sure-controlled A/C ventilation with 10 cmH2O PEEP. You observe continuous bubbling in the water seal chamber of his pleural drainage system. Which of the following is the most likely cause of this observation?-the patient has a pleural effusion 3 / 4

4 / 78

-the suction/ vacuum pressure is too low -the drainage system is obstructed

-the patient has a bronchopleural fistula:

Answer the patient has a bronchopleural fistula

• Constant bubbling indicates a leak; either in the patient or in the

tubing/chamber system.

7.To measure the amount of auto-PEEP present in a patient receiving

ventila- tory support, you would:

-measure pressure during an end-expiratory pause -measure expiratory flow before and after bronchodilator -measure pressure at volume increments using a super syringe

-measure pressure during an end-inspiratory pause:

Answer measure pressure during an end-expiratory pause 8.Which of the following indicate that a pleural drainage system is working properly?

1.the water seal chamber level rises and falls with breathing 2.there is continuous bubbling in the suction control chamber 3.there is continuous bubbling in the water seal chamber 1, 2, and 3

• only
