premature ventricular contraction (PVC) correct answersA patient has had 12-lead ECG testing once per
week for three weeks. The last ECG shows the following tracing. What can be identified in this tracing?
(PVC)
use of a chamber. correct answersA patient with COPD is being instructed on the use of a metered dose
inhaler (MDI). During instruction, the respiratory therapist notes that the patient is unable to coordinate
the actuation of the inhaler with inhalation, despite repeated attempts at instruction. The therapist
should recommend
Miller correct answersDuring intubation by direct laryngoscopy, the laryngoscope blade is inserted past
the vallecula before upward pressure is applied. Which of the following laryngoscope blade types is in
use?
oxygen consumption correct answersC(a-v)O2 values have been increasing over the last eight hours on a
patient who is post-operative for coronary artery bypass. Which of the following is most likely
increasing?
continue mechanical ventilatory support. correct answersA patient is receiving mechanical ventilatory
support by VC ventilation in the A/C mode following a bariatric surgery. Current ventilatory parameters
show:
MIP -32 cm H2O
VT(spont) 7 mL/kg
VC 12 mL/kg
RSBI 86
Qs/Qt 10%
A-aDO2 110 mm Hg
ABGs
pH 7.35
,PaCO2 44 torr
PaO2 87 torr
The patient follows most commands but has confusion regarding person, time, and place. The
respiratory therapist should
Calibration should be done on the analyzer. correct answersA respiratory therapist is utilizing a point-of-
care blood gas analyzer on a critically ill patient in the cardiac intensive care unit (CICU). Which of the
following is the most important consideration prior to use of the analyzer?
incineration correct answersWhich method of sterilization is most appropriate for used disposable
needles?
flow correct answersWhich of the following should be adjusted, given the following ventilator graphic on
a patient receiving VC A/C ventilation? (DICROTIC NOTCH DURING INSPIRATORY BREATHING)
COPD correct answersWhich of the following patients would benefit most by inspiratory muscle training
(IMT)?
AutoPEEP determination correct answersA patient is receiving VC A/C ventilation at a rate of 18/min, VT
600 mL, FIO2 0.6, PEEP 5 cm H2O, I:E ratio of 1:1.8. A flow-time ventilator graphic shows the exhalation
phase fails to return to baseline prior to the initiation of the inspiratory phase, possibly promoting air-
trapping. What additional data would be helpful in further assessing this problem?
decrease in I:E ratio correct answersA patient with COPD, who is receiving mechanical ventilation, is
determined to have an increasing level of autoPEEP. Which of the following would help to alleviate this
situation?
leukocyte count correct answersWhich of the following laboratory values would help to determine the
presence of a blood-borne infection?
, distance correct answersA respiratory therapist is documenting the results of a six-minute walk test
(6MWT). Which of the following is the primary criterion to be documented?
avoid patient testing. correct answersPrior to performing pulmonary function testing on several patients,
a respiratory therapist is performing quality control on the pneumotachometer. After injecting a 3.0 L
syringe through the pneumotachometer, the therapist notes a measurement of 2.81 L. Based on this
result the therapist should
decreasing FIO2 to 0.55. correct answersA 75-kg (165 lb), 180-cm (5-ft, 11-in) patient with left-side heart
failure is in the intensive care unit (ICU) receiving VC SIMV ventilation on the following settings:
reduced SVC values correct answersA 32-year old patient has had kyphoscoliosis since childhood. Which
of the following is most likely?
flushing the PA catheter. correct answersA patient in the ICU has a pulmonary artery catheter in place.
The following pressure waveform is showing on the monitor.
The respiratory therapist should consider (pap 30/8)
use of a subglottic suction device correct answersA patient with COPD is placed on mechanical
ventilatory support after being intubated orally. Proceedings from the multi-disciplinary care council
identifies elevated risk for ventilatory associated pneumonia. Which of the following would help to
minimize this risk?
cardioversion for atrial tachycardia correct answersFor which of the following would conscious sedation
mostly like be employed?
