105 TMC EXAM 6 Latest Actual Questions & Verified Answers Correctly 1.The respiratory therapist should evaluate which of the following to develop a teaching plan for a patient who will be using a metered dose inhaler (MDI) at home?A.manual dexterity and language skills B.disease history and current diagnosis C.visual acuity and color blindness D.highest achieved grade level and GPA

Answer: A

Explanation: A patient taking nebulizer treatments should be able to

demonstrate manual dexterity, or the ability to hold and manipulate the nebulizer device. It is also important that they demonstrate appropriate language skills so they may understand the instruction provided them regarding the use of the device. Their ability to see, or visual acuity, and disease history is not important or critical in learning how to use a nebulizer device.

2.Which of the following should be excluded in an evaluation of a patient's ability to learn to self-administer medication by metered dose inhaler

(MDI)? 1 / 4

• /

105 A.manual dexterity B.language skill C.level of dementia D.disease history

Answer: D

Explanation: A patient that is taking nebulizer treatments needs to be

able to demonstrate manual dexterity, and the ability to hold and manipulate the nebulizer. During the instruction, appropriate language skills and mental capabilities are also important. The patient should also have the mental ability to learn. What is NOT important is the patient's disease history. This will have no effect on their ability to self administer nebulizer treatments.

3.How is exhaled volume determined with IPPB?A.Directly measured at the exhalation valve outlet B.Pre-set using the tidal volume control knob C.Peak- inspiratory pressure divided by flowrate D.Calculation using Dalton's law of partial pressures

Answer: A

Explanation: IPPB machines are pressure ventilators without volume

measuring devices. Tidal volume must be measured externally at the exhalation port. 2 / 4

105 4.In preparing to cap a fenestrated tracheostomy tube on a patient who is scheduled for speech therapy, the respiratory therapist should remember to A.deflate the cuff and remove the inner cannula B.inflate the cuff C.switch to a liquid diet 8 hours prior to speech therapy D.evacuate the foam cuff

Answer: A

Explanation: In order to configure a fenestrated tracheostomy tube for

speech, the button or cap must be placed on the tube after the inner cannula is removed and the cuff is deflated.

5.While performing manual ventilation with a self-inflating resuscitator bag through a properly placed endotracheal tube, a respiratory therapist observes no chest rise. To troubleshoot the problem, the therapist should A.adjust the PEEP valve B.increase the flowrate.C.assure the large bore reservoir tubing is connected.D.check for proper function of the air inlet valve.

Answer: D

Explanation: The scenario suggests that the ET tube is properly placed, 3 / 4

105 therefore the problem must be in the resuscitator. When the therapist squeezes the device, the air is not being delivered to the patient, which is why there is no chest rise.

6.You are called to the emergency room to provide ventilation with a manual resuscitator for a patient receiving CPR. The patient is intubated and the endotracheal tube position has been confirmed. It is difficult to squeeze the bag. A possible causes is A.low pulmonary compliance.B.insufficient oxygen flow to the bag C.a deflated ET tube cuff D.right maintstem bronchus

Answer: A

Explanation: A trained respiratory therapist is able to assess the

appropriate effort required to manually ventilate a patient by squeezing a resuscitator bag. There are numerous causes of increased difficulty in squeezing the bag, including low pulmonary compliance.

7.Which of the following equipment is required to determine VD/VT ratio on a patient receiving mechanical ventilation?A.Fleisch pneumotachometer B.EZ® cap CO2 detector
