If the temperature of a gas decreases:
A) molecular activity increases
B) molecular activity decreases
C) molecular activity remains the same
D) the concentration gradient increases
Q. 2 Which of the following are assumptions regarding the kinetic theory of gases?
I. Gases are composed of discrete molecules.
II. Gas molecules are in random motion.
III. All collisions between molecules are elastic in nature.
IV. Temperature affects the molecular activity.
A) I
B) I and II
C) I, II, and III
D) I, II, III, and IV
Q. 3 While the therapist provides HFJV to a neonate, which of the following factors serve as the basis for establishing ventilator settings? I. peak and airway pressure monitoring II. arterial blood gas data III. capnography data IV. visual inspection of the neonate's thorax
A. I, II only
B. II, III only
C. I, II, III only
D. I, II, IV only
Q. 4 The therapist is setting up an INOvent to administer inhaled NO to a neonatal patient. The therapist wants to deliver a concentration of 20 ppm of NO to this patient. What must the therapist do to the INOvent before attaching it to the patient?
A. Disconnect the INOvent from the Y-piece in the inspiratory breathing circuit before turning on the flowmeter.
B. Turn off the following alarms before setting the O2 flow and the injector: loss of gas pressure, calibration required, and delivery system failure.
C. Set an O2 flow of 15 L/minute and squeeze the bag four times to clear residual NO2.
D. Activate the dual channels to control NO delivery and to monitor the INOvent output.
Q. 5 A patient is receiving iNO via the INOvent delivery system. The therapist is concerned that the patient will not receive a constant NO concentration because the patient experiences altered ventilatory flow patterns. What should the therapist do to ensure that a constant NO concentration is delivered to the patient?
A. Do nothing because the INOvent ensures that a constant NO concentration is delivered.
B. Set the INOvent on the variable ventilatory pattern mode to ensure a constant NO concentration is delivered.
C. Activate the injection module on the INOvent to ensure a constant NO concentration is delivered.
D. Because the range of variation of the delivered iNO dose is so small, the concern is unimportant.
Q. 6 What physiologic response is caused by inhaled nitric oxide?
A. systemic vasodilatation
B. pulmonary vasodilatation
C. increased cardiac output
D. increased gastrointestinal motility
