TMC EXAM A LATEST UPDATED 2024 QUESTIONS WITH 100% CORRECT ANSWERS

A patient who complains of dyspnea is noted to have a dry, non-productive cough. On
physical examination, breath sounds are diminished on the right, tactile fremitus is
decreased and there is dullness to percussion over the right lower lobe. The respiratory
therapist should suspect that the patient is suffering from pleural effusion
Which of the following suction catheters would be appropriate to use for a patient with a size
8.0 mm ID endotracheal tube? 12 Fr
A patient who is receiving continuous mechanical ventilation is fighting the ventilator. His
breath sounds are markedly diminished on the left, there is dullness to percussion on the
left, and the trachea is shifted to the left. The most likely explanation for the problem is that
the endotracheal tube has slipped into the right main stem bronchus.
The respiratory therapist notes a developing hematoma after an arterial blood gas was
drawn from the right radial artery. The immediate response is to apply pressure to
the site
A patient's breathing pattern irregularly increases and decreases and is interspersed with
periods of apnea up to 1 minute. Which of the following conditions is the most likely cause of
this problem?elevated intracranial pressure
What value for the apnea-hypopnea index (AHI) is consistent with mild obstructive sleep
apnea? 5 to 15
While monitoring a newborn utilizing a transcutaneous monitor, the respiratory therapist
notices a change in PtcO2 from 60 to 142 torr and simultaneously the PtcCO2 changes from
37 to 2 torr. What is the most likely explanation for these changes? air leak around the
sensor
A patient on the general medical ward receives oxygen via 28% air entrainment mask with
the flowmeter set at 5 L/min. What is the total flow delivered to the patient? 55 L/min
Which of the following measurements is most indicative of congestive heart failure?
pulmonary capillary wedge pressure of 30 mmHg
Sleep apnea can be defined as repeated episodes of complete cessation of airflow for10
seconds or longer
A patient in the ICU receiving mechanical ventilation underwent fiberoptic bronchoscopy
during which a tissue biopsy was collected. Immediately following the procedure, the
respiratory therapist notes that the peak inspiratory pressure on the ventilator has
increased. Potential causes for this include all of the following EXCEPT hypoxemia
What size endotracheal tube would be appropriate for an adult female patient?7.0 to 7.5 mm
The respiratory therapist is asked to evaluate the presence of Auto-PEEP on a patient
receiving mechanical ventilation. In order to do this, the therapist should initiate an
expiratory hold just prior to the next ventilator-delivered breath.
A patient who suffered trauma in an ATV accident is being monitored in the ICU. A pulmonary
artery catheter has been placed and the following data is available:
PCWP 4 mm Hg
PAP (mean) 8 mm Hg
CVP 2 cm H2O
Cardiac Output 3L/min
A 48 year-old female is admitted to the ED with diaphoresis, jugular venous distension, and
3+ pitting edema in the ankles. These findings are consistent with heart failure
A patient is admitted to the ED following a motor vehicle accident. On physical exam, the
respiratory therapist discovers that breath sounds are absent in the left chest with a
hyperresonant percussion note. The trachea is shifted to the right. The patient's heart rate
is 45/min, respiratory rate is 30/min, and blood pressure is 60/40 mm Hg. What action
should the therapist recommend first? Needle aspirate the 2nd left intercostal space
All of the following strategies are likely to decrease the likelihood of damage to the tracheal
mucosa EXCEPT using a low residual volume, low compliance cuff
A 52 year-old post-operative cholecystectomy patient's breath sounds become more coarse
upon completion of postural drainage with percussion. The respiratory therapist should
recommend deep breathing & coughing to clear secretions
A 65 kg spinal cord injured patient develops atelectasis. His inspiratory capacity is 30% of
his predicted value. What bronchial hygiene therapy would be most appropriate initially?
IPPB
A healthy adult female can exhale what portion of her forced vital capacity in the first
second? 70%
A patient on VC ventilation demonstrates auto-PEEP on ventilator graphics. Which of the
following controls, when adjusted independently, would increase expiratory time?
1. Tidal volume
2. respiratory rate
3. inspiratory flow
4. sensitivity 1, 2, and 3 only
Which of the following would be the most appropriate therapy for a dyspneic patient who has
crepitus with tracheal deviation to the left and absent breath sounds on the right? insert
a chest tube
Following cardiac surgery, a 55 year-old patient has the following ABG results: pH 7.50,
PaCO2 30 torr, PaO2 62 torr, HCO3 25 mEq/L, SaO2 92%, HB 14 g/dL, BE +2. Venous blood
gas results are pH 7.39, PvCO2 43 torr, PvO2 37 torr, and SvO2 66%. Calculate the patient's
C(a-v)O2. 5.0 vol %
A patient on VC, SIMV with a VT of 500 mL has a PIP of 25 cm H2O, Pplat of 15 cm H2O and
PEEP of 5 cm H2O. What is the patient's static lung compliance? 50 mL/cm H2O
Immediately after extubation of a patient in the ICU, the respiratory therapist observes
increasing respiratory distress with intercostal retractions and marked stridor. The SpO2
on 40% oxygen is noted to be 76%. Which of the following would be most appropriate at this
time? Reintubation
