A 72 year-old female post stem cell transplant patient in the ICU is complaining of difficulty breathing and is noted to have diffuse fluffy infiltrates on chest X-ray. The B-type Natriuretic Peptide (BNP) test result demonstrates 700 pg/mL. What is the patient's possible condition?

• severe heart failure
• respiratory distress syndrome
• severe renal failure
• moderate heart failure - ---Answers___-moderate heart

failure

Following blunt chest trauma, a 35-year-old male is orally intubated and continuous mechanical ventilation is initiated.Physical assessment of the neck and chest reveal a midline trachea and significant reduction in thoracic expansion of the left chest. There are diminished breath sounds in the left lung compared to the right lung. These findings most likely indicate which of the following?

• flail chest on right thorax 1 / 4

• right tension pneumothorax
• endobronchial intubation
• subcutaneous emphysema - ---Answers___-endobronchial

intubation

A patient receiving pressure-controlled ventilation has acute hypoventilation with an ETCO2 of 70 torr. His vital signs

include: heart rate 90/min, respiratory rate 18/min, SpO2 94%.

Which of the following change(s) will address the situation?

• Increase the pressure limit
• Increase the sensitivity
• Increase the mandatory rate
• Decrease the inspiratory time - ---Answers___-1 and 3

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 - ---Answers___-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. - ---Answers___-

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. - ---Answers___-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 3 / 4

disinfecting the surface of the pulse oximeter between patients?

• 70% ethyl alchohol
• Warm soapy water
• Bleach
• Acid glutaraldehyde - ---Answers___-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.
• myasthenia gravis.
• acute asthmatic attack.
• left tension pneumothorax. - ---Answers___-left tension

pneumothorax.

The most serious complication associated with airway suctioning is

• hypoxemia.
• bradycardia.
• mucosal trauma.
• gag reflex stimulation. - ---Answers___-hypoxemia.
