During cardiopulmonary resuscitation, a patient's cardiac rhythm and pulse are revived.
Because IV access has been impossible, epinephrine and other code medications have been
administered by endotracheal instillation. The follow up ECG shows a normal tracing with a
heart rate of 55 bpm. The respiratory therapist should suggest a(n)
A. Pronestyl given sublingually.
B. ET instillation of atropine sulfate.
C. IM bolus of epinephrine.
D. cardiac pacing with synchronization set to active.
The correct answer is : B
While performing a pre-operative test on a volume-controlled ventilator with a test lung, the
machine emits a sound related to a low-volume alarm during the assessment. For which of the
following should the respiratory therapist check first?
A. faulty pressure transducer
B. perforation in the test lung
C. inadequate circuit connections
D. malfunctioning Clark electrode
,The correct answer is : C
A patient is placed on a VC ventilator immediately after bariatric surgery. Due to slow
emergence from sedation, the patient is transferred from the recovery unit to the intensive care
unit (ICU) to rest for the night while receiving ventilatory support on the following settings:
FIO2 0.45
Mode SIMV
Mandatory rate 14/min
VT 650 mL
PEEP 5 cm H2O
I:E ratio 1:2
The respiratory therapist notices that the initial volume-pressure ventilator graphic
demonstrates a small 'bird beak' indicating a slight amount of overdistension. However, the
most current graphic no longer shows the overdistension despite no change in tidal volume.
What could best explain this?
A. There is an increase in atelectasis.
B. Alveoli were naturally recruited.
C. There is an increase in dynamic compliance.
D. A pleural effusion is present.
The correct answer is : B
Which of the following conditions should cardiac compressions be started?
1. atrial tachycardia
2. confirmed asystole
,3. heart rate of 35/min
4. complete loss of ventilation
A. 1, 2, 3, and 4
B. 2 and 3 only
C. 2 and 4 only
D. 2, 3, and 4 only
The correct answer is : B
The following data is available on a 61-kg (135-lb) male patient receiving VC SIMV ventilation:
Ventilator settings:
FIO2 0.45
VT 450 mL
PEEP 4 cm H2O
Mandatory rate 12/min
ABGs
pH 7.41
PaCO2 39 mm Hg
PaO2 85 mm Hg
HCO3- 24 mEq/L
BE 0 mEq/L
If PAO2 is determined to be 204 mm Hg, which of the following best represents the patient's
condition?
A. pulmonary embolism
, B. venous admixture (shunting)
C. V/Q mismatching
D. pulmonary hypertension
The correct answer is : C
Which of the following is used to assess a patient's cardiac work load ability?
A. oximetry with ambulation
B. ECG
C. 6-minute walk test
D. DLCO
The correct answer is : C
A patient diagnosed with obstructive sleep apnea has returned to the polysomnography lab for
a titration study with a full-face mask. During the night, despite raising the CPAP pressure to 15
cm H2O, the patient continues to demonstrate hypoventilation and the inability to achieve stage
IV sleep. Which of the following would be an appropriate next step?
A. raise CPAP to 20 cm H2O and reassess
B. document a failed titration, refer to surgery for soft tissue resection
C. switch to bi-level therapy
D. switch to a nasal mask
The correct answer is : C
A patient is taking xanthine medication to help control asthma symptoms. They have orders for
Theo-dur (theophylline) 400 mg extended release by mouth daily. After three weeks of
