ARDS Nursing Sem 4 (Lewis) Questions and
Answers (100% Correct Answers) Already
Graded A+
Which diagnostic test will provide the nurse with the most
specific information to evaluate the effectiveness of
interventions for a patient with ventilatory failure?
a.
Chest x-ray
b.
O2 saturation
c.
Arterial blood gas analysis
d.
Central venous pressure monitoring [ Ans: ] ANS: C
Arterial blood gas (ABG) analysis is most useful in this
setting because ventilatory failure causes problems with
CO2 retention, and ABGs provide information about the
PaCO2 and pH. The other tests may also be done to help in
assessing oxygenation or determining the cause of the
patient's ventilatory failure.
,While caring for a patient who has been admitted with a
pulmonary embolism, the nurse notes a change in the
patient's oxygen saturation (SpO2) from 94% to 88%. Which
action should the nurse take?
a.
Suction the patient's oropharynx.
b.
Increase the prescribed O2 flow rate.
c.
Instruct the patient to cough and deep breathe.
d.
Help the patient to sit in a more upright position. [ Ans: ]
ANS: B
Increasing O2 flow rate will usually improve O2 saturation
in patients with ventilation-perfusion mismatch, as occurs
with pulmonary embolism. Because the problem is with
perfusion, actions that improve ventilation, such as deep
breathing and coughing, sitting upright, and suctioning,
are not likely to improve oxygenation.
A patient with respiratory failure has a respiratory rate of
6 breaths/min and an oxygen saturation (SpO2) of 88%.
,The patient is increasingly lethargic. Which intervention
will the nurse anticipate?
a.
Administration of 100% O2 by non-rebreather mask
b.
Endotracheal intubation and positive pressure ventilation
c.
Insertion of a mini-tracheostomy with frequent suctioning
d.
Initiation of continuous positive pressure ventilation
(CPAP) [ Ans: ] ANS B
The patient's lethargy, low respiratory rate, and SpO2
indicate the need for mechanical
ventilation with ventilator-controlled respiratory rate.
Giving high-flow O2 will not be helpful
because the patient's respiratory rate is so low. Insertion
of a mini-tracheostomy will facilitate
removal of secretions, but it will not improve the patient's
respiratory rate or oxygenation.
, CPAP requires that the patient initiate an adequate
respiratory rate to allow adequate gas
exchange.
The oxygen saturation (SpO2) for a patient with left lower
lobe pneumonia is 90%. The
patient has wheezes, a weak cough effort, and complains
of fatigue. Which action should the
nurse take next?
a. Position the patient on the left side.
b. Assist the patient with staged coughing.
c. Place a humidifier in the patient's room.
d. Schedule a 4-hour rest period for the patient. [ Ans: ]
ANS: B
The patient's assessment indicates that assisted coughing
is needed to help remove secretions,
which will improve oxygenation. A 4-hour rest period at
this time may allow the O2 saturation
to drop further. Humidification will not be helpful unless
the secretions can be mobilized.
