N432 exam 1 Davis edge QUESTIONS
AND ANSWERS GRADED A+
The charge nurse is revising the ventilated patients in the intensive care unit for their risk of
developing acute respiratory distress syndrome (ARDS). Which patients should be most closely
monitored for symptoms? Select all that apply. - correct answer ✔✔ * 88 year old with
aspiration pneumonia after a stroke (aspiration is a high risk for ARDS development)
* 19 year old involved in a multi-car accident (severe trauma such as a car accident is a risk
factor for ARDS)
* 45 year old who had a five-vessel coronary bypass graft surgery (those who have been on
cardiopulmonary bypass are at risk)
x 54 year old with a colostomy from diverticulitis (abdominal surgeries are not higher risk,
unless in the presence of sepsis)
* 62 year old with a left lobe removal from lung cancer (a pneumonectomy is a risk factor)
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 - correct 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? -
correct 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? - correct 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? - correct 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
The nurse is caring for a patient with acute respiratory distress syndrome (ARDS) whose
condition is deteriorating. What ventilatory options may be considered to improve refractory
hypoxemia? Select all that apply. - correct answer ✔✔ * reduce the tidal volume (the most
common is conventional ventilation using reduced tidal volumes and positive end-expiratory
pressure (PEEP). This allows the alveoli to open and remain open while at the same time
keeping peak airway pressure low.
