TMC PRACTICE EXAM UPDATED

ACTUAL EXAM WITH CORRECT SOLUTIONS.

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

• liver failure.
• pulmonary embolism.
• heart failure.
• electrolyte imbalances - correct answer- 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?

• Call for a STAT chest x-ray.
• Insert a chest tube into the left chest.
• Needle aspirate the 2nd left intercostal space. 1 / 4

• Activate the medical emergency team to intubate the patient.
• correct answer- 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

• maintaining cuff pressures between 20 and 25 mm Hg.
• using the minimal leak technique for inflation.
• using a low-residual-volume, low-compliance cuff.
• monitoring intracuff pressures. - correct answer- monitoring

intracuff pressures.

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

• continuing the therapy until breath sounds improve.
• administering dornase alpha.
• administering albuterol therapy.
• deep breathing and coughing to clear secretions. - correct

answer- deep breathing and coughing to clear secretions.
