• Obstructive apnea . Answer: During sleep, which of the following is
characterized by cessation of airflow for 10 seconds associated with
paradoxical movement of the chest and abdomen?
• worsened . Answer: A patient is admitted to the ED for asthma. An RT
auscultates loud wheezing. Following two bronchodilator treatments,
BBS and wheezes are markedly diminished. RT should conclude the
patient's bronchospasm has
• Body temp greater than 36 Celsius (96.8) . Answer: An RT is asked to
perform an apnea test on a patient for whom brain death is clinically
suspected. Which of the following should be confirmed prior to
performing the test?
• Patient is ready for extubation . Answer: A 22 year old patient is being
considered for possible extubation after being treated for status
asthmaticus over the past 48 hours. breath sounds are clear and no
current distress is noted. While receiving an FIO2 of 0.40, Ps of 6 cm
h20 of PEEP for one hour, her vital signs are

an RT should conclude?
, • The sample site was warmed to 36° C (96.8° F). . Answer:
Transcutaneous monitoring of a 3-week-old female in the NICU with an
SpO2 of 97% reveals a PTCCO2 of 42 mm Hg. ConcurrentCBG
analysis results are:pH 7.37PCO2 62PO2 46HCO3- 36BE +8SO2 (calc)
81%Which of the following is the most likely cause of the discrepancy
in this patient's values?
• continue current o2 therapy . Answer: The patient with pulmonary
emphysema has been receiving 24% oxygen for 30 minutes. PaCo2 has
risen from 45 to 48 mmHg, and PaO2 has risen from 45 to 60 mmHg.
Which of the following should an RT do next?
• decrease the fio2 . Answer: The following CBG results are obtained for
a 34-week gestational age infant receiving 35% oxygen by nasal cannula
at 0.5 L/min:pH 7.34PCO2 45 mm HgPO2 52 mm HgHCO3- 24

therapist should recommend
• premature ventricular complexes . Answer: the following ECG tracting
is observed
• check integrity of ETT cuff . Answer: A RT notes a prolonged i time
and variable cycling to exhalation for a patient receiving PS ventilation.
Circuit is intact. RT should NEXT
• water in the tubing . Answer: RT is checking jet nebulizer with an
entrainment setting of 35%. A properly calibrated o2 analyzer measures
the concentration at 45%. What best explains this finding?
