DAVIS EDGE CARDIAC PART 1
EXAMINATION TEST 2026 QUESTIONS AND
SOLUTIONS GRADED A+
⩥ The nurse is caring for a patient with an increased risk for developing
acute respiratory distress syndrome (ARDS). Calculate the ARDS ratio
if the patient's PaO2 is 70 on an FiO2 of 60%. Round to the nearest
whole number. Enter numeral only.
Answer
Correct Answer: 117
Rationale: To calculate the ARDS ratio, divide the PaO2 by the percent
of FiO2. 70/0.60 = 116.6 = 117 Answer: to calculate the ARDS ratio,
70/0.60 = 117
⩥ The nurse is caring for a patient with acute respiratory distress
syndrome with a severity ratio of 101 on positive end-expiratory
pressure (PEEP). What category of severity is this patient? Answer:
moderate.
x Mild
Rationale: This is a severity ratio of 200-300 on ventilator settings that
include positive end-expiratory pressure (PEEP) or continuous positive
airway pressure (CPAP).
, * Moderate
Rationale: This is a severity ratio of 100-200 on ventilator settings that
include PEEP.
x Progressive
Rationale: This is not a severity ratio option.
x Severe
Rationale: This is a severity ratio of less than 100 on ventilator settings
that include PEEP.
Test Taking
⩥ During the early stages of acute respiratory distress syndrome
(ARDS), the nurse should monitor for which arterial blood gas change?
Answer: respiratory alkalosis
arterial blood gases initially reveal a respiratory alkalosis due to the
tachypnea
⩥ The nurse is reviewing the chest x-ray report of a ventilated patient
requiring an FiO2 of 70%. Which finding is most concerning? Answer:
bilateral infiltrates
during the early phases of acute respiratory distress syndrome (ARDS),
serial chest x-ray can be used to identify the bilateral infiltrates that are
the hallmark sign of this disease process
