A 60 year-old male has just been extubated following coronary artery bypass grafting.

His chest X-ray demonstrates platelike infiltrates with scattered densities and he is

noted to have decreased chest expansion with an increased respiratory rate. Which of

the following treatments should be recommended for this patient?

• diuretics

• antibiotics

• lung expansion therapy

• thoracentesis - ANSWER- lung expansion therapy

A 42 year-old trauma patient in the ED has been intubated with a 6.5 mm oral

endotracheal tube equipped with a high-residual-volume, low-pressure cuff. The

respiratory therapist notes that a cuff pressure of 42 cm H2O is necessary to achieve a

minimal occluding volume. This would indicate that the

• tube is not of the appropriate size.

• pilot balloon and line are obstructed.

• pressure manometer is defective.

• cuff has herniated over the tip of the tube. - ANSWER- tube is not of the appropriate

size.

A patient is receiving oxygen via nasal cannula at 2 L/min and has the following ABG

results: pH 7.37, PaCO2 42 torr, PaO2 80, HCO3 38 mEq/L. The most likely

explanation for these results is that

• the sample was not iced properly.

• there was excess heparin in the syringe.

• the numbers were not reported correctly.

• The sample contains venous blood. - ANSWER- the numbers were not reported

correctly.

The respiratory therapist is completing oxygen rounds on the ward and checking oxygen

saturations on a number of patients. What solution would be most appropriate for

disinfecting the surface of the pulse oximeter between patients?

• 70% ethyl alchohol

• Warm soapy water

• Bleach

• Acid glutaraldehyde - ANSWER- 70% ethyl alchohol

Evaluation of a spontaneously breathing patient reveals tachypnea, tracheal deviation to

the right and an absence of breath sounds on the left. The most likely etiology would be

• bronchiectasis.

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 - 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.

• Activate the medical emergency team to intubate the patient. - 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. - 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. - ANSWER- deep breathing and

coughing to clear secretions.Downloaded by zena ahmad ([email protected]) lOMoARcPSD|35287698
