A 52 year-old post-operative cholecystectomy patient's breath sounds
become more coarse upon completion of postural drainage with percussion.
The respiratory therapist should recommend:

B. administering dornase alpha.
C. administering albuterol therapy.
D. deep breathing and coughing to clear secretions. - Correct answer-D. deep

See Patient Assessment
A healthy adult female can exhale what portion of her forced vital capacity in
the first second? - Correct answer-70%
Following cardiac surgery, a 55 year-old patient has the following ABG
results: pH 7.50, PaCO2 30 torr, PaO2 62 torr, HCO3 25 mEq/L, SaO2 92%,
HB 14 g/dL, BE +2. Venous blood gas results are pH 7.39, PvCO2 43 torr,
PvO2 37 torr, and SvO2 66%. Calculate the patient's C(a-v)O2. - Correct
answer-5% volume
What value for the apnea-hypopnea index (AHI) is consistent with mild
obstructive sleep apnea? - Correct answer-5 to 15
The respiratory therapist is asked to evaluate the presence of Auto-PEEP
on a patient receiving mechanical ventilation. In order to do this, what
should the RT do? - Correct answer-Initiate an expiratory hold just prior to
the next ventilator-delivered breath
What do bronchial breath sounds heard over the lung periphery
indicate? - Correct answer-lung consolidation (pneumonia)
Rationale: should be vesicular in periphery
,A 60 kg (132 lb) patient is mechanically ventilated at the following settings:
VC, A/C; VT 500 mL, respiratory rate 12/min, FIO2 1.00 and 10 cm H2O
PEEP. The patient's peak airway pressure is 60 cm H2O and his SpO2 is 85%.
A current chest x-ray shows diffuse bilateral infiltrates. Which of the
following is the most appropriate action in order to reduce peak airway
pressure?
A. Increase the frequency.
B. Change to airway pressure release ventilation.
, C. Decrease the inspiratory time.
D. Increase PEEP to 15 cm H2O. - Correct answer-B. Change to airway
pressure release ventilation.
A 19-year-old patient is brought to the Emergency Department after taking a
handful of pills. The patient is obtunded but is making regular, sonorous
respiratory efforts.
Auscultation reveals coarse rhonchi bilaterally. Which of the following should
be done FIRST to assess this patient?
A. Obtain a sputum specimen.
B. Obtain an ABG.
C. Measure peak expiratory flow.
D. Determine the Glasgow Coma Score. - Correct answer-B. Obtain an ABG.
A young healthy adult with complaints of intermittent wheezing is seen in the
pulmonary clinic. A pre/post bronchodilator spirometry reveals a normal
study with no reversibility. Which of the following should the respiratory
therapist recommend?
A. Helium dilution study
B. DLCO
C. Plethysmography
D. Bronchial provocation - Correct answer-D. Bronchial provocation
Following abdominal surgery, a 70 year-old patient receives mechanical
ventilation in the ICU at the following settings: VC, A/C; VT 550 mL,
respiratory rate 14/min, FIO2
0.50 and 10 cm H2O PEEP. Bedside monitoring results demonstrate that the
PvO2 is 35 torr and the SpO2 is 90%. The patient is alert and oriented
with stable vital signs. Which of the following should the respiratory
therapist recommend?
A. Decrease the PEEP.
B. Increase the FIO2.
C. Initiation diuretic therapy.
D. Continue to monitor closely. - Correct answer-B. Increase the FIO2.
The respiratory therapist obtains a blood gas sample from the patient's radial
artery and applies pressure to the site for 10 minutes. After removing any
excess air from the syringe, the next step for proper handling of the blood
sample is:
A. adding liquid heparin to the sample.
B. placing the syringe in an ice bath.
C. shaking the sample continuously.
