A 1600g neonate is receiving O2 by oxyhood at an FiO2 of 0.60. the flowmeter is set at 5L/min. While analyzing the O2, the RT notices varying FiO2 readings at a different locations inside the oxyhood. Which of the following should the RT do to correct the problem?

• Re-calibrate the O2 analyzing device
• Increase the flow to the oxyhood
• Place the neonate in an isolette at an FiO2 of 0.60

to the oxyhood

A 19 y/o patient has a size 7 mm ID nasotracheal tube placed through the right nare.While attempting to suction the patient with a size 12 Fr catheter, resistance is met as

the catheter is introduced into the ETT. The RT should:

• Lubricate the catheter with petroleum jelly prior to suctioning
• Instill acetylcysteine into the ETT
• Switch to a 10 Fr suction catheter
• Extubate the patient and reintubate with a size 9 mm ID ETT - CORRECT ANSWER:
• Switch to a 10 Fr suction catheter

A 2 y/o child with croup has been intubated for 4 days with a 4mm ID uncuffed ETT.Heated aerosol at an FiO2 of 30% has been delivered to the patient. The physician asks the RT to evaluate the pt for possible extubation. Which of the following would most likely indicate that the pt is ready for extubation?

• Pt is making normal quiet ventilatory efforts 1 / 3

• Negative sputum culture and sensitivity has been reported
• Pt's ABG are within normal range

D. Breath sounds are heard around the tube on auscultation - CORRECT ANSWER: D.

Breath sounds are heard around the tube on auscultation

A 43 y/o female patient has just undergone a total abdominal hysterectomy. The pt arrives in the post anesthesia care unit obtunded with minimal response to painful

stimulus. what treatment should the RT recommend for this pt? - CORRECT ANSWER:

A 58 y/o male patient is hypoxic on volume control ventilation and is receiving 15 cm H20 of PEEP on an FiO2 0.60. Shortly after increasing the PEEP therapy to 18 cm H20, the RT notes that the systemic blood pressure has fallen from 110/72 mm Hg to 94/50 mm Hg and the cardiac output has fallen from 4.3 L/min to 2.5 L/min. The most

appropriate action at this time would be to:

• maintain the present therapy and re-evaluate the patient in thirty minutes
• decrease the PEEP to 15 cm H20 and increase the FiO2 to 0.70
• decrease the PEEP to 12 cm H20 and maintain the FiO2 at 0.60

D. discontinue the PEEP and increase the FiO2 to 0.80 - CORRECT ANSWER: B.

decrease the PEEP to 15 cm H20 and increase the FiO2 to 0.70
