Before administering prescribed oxygen therapy via face mask, the nurse would
assess whether the patient has a history of which problem? - ANSWER-
Claustrophobia
Face masks may cause anxiety in the patient with claustrophobia, worsening the
symptoms of respiratory distress. Hyperglycemia is not a contraindication to or
complication of face mask use. Deviated septum may make a nasal cannula
uncomfortable but would not affect the use of a face mask. Addison's disease will
not affect the use of a face mask, although prescribed corticosteroid dose may be
affected by Addison's disease.
Which finding in patient with possible acute respiratory distress syndrome (ARDS)
is most important for the nurse to communicate to the health care provider? -
ANSWER-PaO2/FIO2 (P/F) ratio decrease from 300 to 100
Since a P/F ratio change from 300 to 100 indicates severe ARDS, the nurse will
rapidly report this change to the health care provider and expect immediate
changes in the patient's treatment such as use of noninvasive positive pressure
ventilation, intubation, and mechanical ventilation. The elevated heart rate is a
compensatory mechanism for hypoxemia but is not as clear an indicator of ARDS.
A chest x-ray showing bilateral infiltrates helps to confirm a diagnosis of ARDS but
does not necessarily need rapid intervention. Bilateral crackles are a common
finding in ARDS but may occur in many other diagnoses that will not require rapid
intervention.

Which finding by the nurse who is caring for a patient with acute respiratory
distress syndrome (ARDS) is most important to report to the health care provider?
- ANSWER-Creatinine 2.8 mg/dL
An elevated creatinine level in a patient with ARDS indicates development of
acute kidney injury and possible multiple organ dysfunction syndrome (MODS).
The nurse will report the creatinine and expect to implement actions such as
further diagnostic testing, fluid infusion, and possibly discontinuing medications
that might cause kidney damage. Because permissive hypercapnia is a common
strategy in ARDS, the PaCO2 does not need to be reported immediately. The
hematocrit is slightly low but does not require immediate medical intervention
such as transfusion. The oxygen saturation is at the low end of normal, which is
acceptable for a patient with ARDS.
In which order do the pathophysiologic changes leading to clinical manifestations
of acute respiratory distress syndrome occur? - ANSWER-Acute injury to the
alveolar-capillary membrane
Damage to type II alveolar cells
Decreased surfactant production
Decreased alveolar compliance and recoil
Atelectasis
Following lung injury and damage to the alveolar capillary membrane,
inflammatory changes lead to damage to the type II alveolar cells, which are
responsible for producing surfactant. As surfactant level decreases, alveoli can no
longer maintain stability and collapse, leading to decreased alveolar compliance

and recoil, and finally resulting in atelectasis. The nurse will observe increased
work of breathing and auscultate lung crackles at this stage.
Which finding by the nurse is the best indicator that measures to improve
oxygenation in a patient on mechanical ventilation for acute respiratory distress
syndrome have been effective? - ANSWER-Oxygen saturation 90% to 93%
Since oxygen saturations of 90% to 93% are in the low normal range, this is the
best indicator that treatment has improved oxygen saturation. Clearing lung
sounds may also indicate improvement, but oxygen saturation is a better indicator
for improvement in oxygenation. Patient report of improvement in dyspnea is also
an indicator of effective treatment, but oxygen saturation in the normal range is a
clearer indicator. Heart rate and BP stabilization also occurs with improvement in
respiratory status but is not as clear an indicator of improvement in oxygenation
as oxygen saturation.
Which finding in a patient with acute respiratory distress syndrome (ARDS) is the
best indicator that placing the patient in the prone position has been effective? -
ANSWER-Oxygen saturation improves.
Prone positioning improves atelectasis and is used for patients with severe ARDS
and refractory hypoxemia to improve oxygenation. Secretions may be mobilized in
the prone position and lead to a more effective cough, but this is not the major
purpose of prone positioning in severe ARDS. Turning the patient to the prone
position may help to prevent skin breakdown, but this is not the reason for prone
positioning. Breath sounds may improve as alveoli in the posterior part of the lung
are able to expand, but the major reason for prone positioning is improvement in
hypoxemia.

When a patient who has been successfully treated for acute respiratory distress
syndrome (ARDS) reports anxiety and vivid dreams that interfere with sleep,
which action will the nurse take? - ANSWER-Refer the patient for counselling.
Survivors of ARDS may have anxiety, depression, poor memory, and posttraumatic
stress disorder as long-term complications, and counselling is helpful in identifying
and addressing these mental health issues. Since the patient has recovered from
ARDS, assessment of oxygen saturation is not needed. There is no data indicating
that the patient has diet or exercise habits that are contributing to the symptoms.
Since the patient data do not indicate delirium or disorientation, assessment of
orientation is not necessary.
When teaching the patient about the use of range of motion (ROM), which
explanations would the nurse give to the patient? Select all that apply. - ANSWER-
ROM will show the patient that movement still is possible.
Active and passive ROM maintain function of body parts.
Movement facilitates mobilization of leaked exudates back into the vascular bed.
The explanations that should be used are that active and passive ROM maintain
the function of body parts and reassure the patient that movement still is
possible. Contractures are prevented with ROM as well as splints. Movement
facilitates mobilization of fluid in the interstitial fluid back into the vascular bed.
Although it is good to collaborate with physical therapy to perform ROM during
dressing changes because the patient has already taken analgesics, ROM can and
should be done throughout the day.
