EVALUATION 2026 COMPLETE QUESTIONS
AND ANSWERS
◉ Phase B of Waveform
Answer: Second phase, abrupt rise in CO2 due to a mixture of
alveolar gas with dead space gas, called the upslope. Also phase B-C.
◉ Phase C of Waveform
Answer: Expiratory or alveolar plateau is represented by phase C-D,
and the gas sampled is essentially alveolar.
◉ Phase D of Waveform
Answer: Point D is maximal ETCO2 level, the best reflection of teh
alveolar CO2 level.
◉ Phase E of Waveform
Answer: Fresh gas is introduced during the inspiratory downstroke
(phase D-E), and the waveform returns to the baseline level of CO2-
approx 0.
◉ Bag Valve Mask
, Answer: Whenever possible, you and your partner should work
together to provide ventilation's with the BVM, to ensure the
artificial ventilations are adequate, you must look for CHEST RISE
AND FALL, make sure the RATE IS NOT TOO FAST or SLOW, and
make sure the PULSE RATE IMPROVES.
◉ CPAP
Answer: CHF pt's, pulm edema, COPD, and acute bronchospasm
(acute asthma), submersion accidents, pulse ox less than 90, and
rapid breathing, are indications for CPAP. Do not use if pt has
abnormal LOC, hypoventilation, pneumothorax, tracheostomy, and
active GI bleed.
◉ PEEP
Answer: Positive end expiratory pressure; during the epxiratory
phase the pt exhales against this resistance. A PEEP of 5-10 is
generally what is used.
◉ Suctioning a Trache
Answer: Preoxygenate, insert 3ml of saline into stoma, instruct the
pt to exhale while inserting the catheter, then begin suctioning on
the way out.
