Critical Care Exam 1 Oxygenation
questions with answers
When preparing a patient with possible asthma for pulmonary function testing, the nurse will
teach the patient to
a.
avoid eating or drinking for several hours before the testing.
b.
use rescue medications immediately before the tests are done.
c.
take oral corticosteroids at least 2 hours before the examination.
d.
withhold bronchodilators for 6 to 12 hours before the examination. - ANS ✔✔withhold
bronchodilators for 6 to 12 hours before the examination.
Bronchodilators are held before pulmonary function testing so that a baseline assessment of
airway function can be determined.
Which information will the nurse include when teaching the patient with asthma about the
prescribed medications?
a.
Utilize the inhaled corticosteroid when shortness of breath occurs.
b.
Inhale slowly and deeply when using the dry-powder inhaler (DPI).
c.
Hold your breath for 5 seconds after using the bronchodilator inhaler.
,d.
Tremors are an expected side effect of rapidly acting bronchodilators. - ANS ✔✔Tremors are an
expected side effect of rapidly acting bronchodilators
Tremors are a common side effect of short-acting b2-adrenergic (SABA) medications and not a
reason to avoid using the SABA inhaler. Inhaled corticosteroids do not act rapidly to reduce
dyspnea. Rapid inhalation is needed when using a DPI. The patient should hold the breath for
10 seconds after using inhalers.
When the nurse is evaluating the effectiveness of therapy for a patient who has received
treatment during an asthma attack, which finding is the best indicator that the therapy has been
effective?
a.
No wheezes are audible.
b.
Oxygen saturation is >90%.
c.
Accessory muscle use has decreased.
d.
Respiratory rate is 16 breaths/minute. - ANS ✔✔ANS: B
The goal for treatment of an asthma attack is to keep the oxygen saturation >90%. The other
patient data may occur when the patient is too fatigued to continue with the increased work of
breathing required in an asthma attack.
A patient seen in the asthma clinic has recorded daily peak flows that are 85% of the baseline.
Which action will the nurse plan to take?
a.
Teach the patient about the use of oral corticosteroids.
b.
, Administer a bronchodilator and recheck the peak flow.
c.
Instruct the patient to continue to use current medications.
d.
Evaluate whether the peak flow meter is being used correctly. - ANS ✔✔ANS: C
The patients peak flow readings indicate good asthma control, and no changes are needed. The
other actions would be used for patients in the yellow or red zones for peak flow.
Which action by a patient who has asthma indicates a good understanding of the nurses
teaching about peak flow meter use?
a.
The patient records an average of three peak flow readings every day.
b.
The patient inhales rapidly through the peak flow meter mouthpiece.
c.
The patient uses the albuterol (Proventil) metered-dose inhaler (MDI) for peak flows in the
yellow zone.
d.
The patient calls the health care provider when the peak flow is in the green zone. - ANS
✔✔ANS: C
Readings in the yellow zone indicate a decrease in peak flow; the patient should use short-
acting b2-adrenergic (SABA) medications. The best of three peak flow readings should be
recorded. Readings in the green zone indicate good asthma control. The patient should exhale
quickly and forcefully through the peak flow meter mouthpiece to obtain the readings.
Which information given by an asthmatic patient while the nurse is doing the admission
assessment is most indicative of a need for a change in therapy?
a.
The patient uses cromolyn (Intal) before any aerobic exercise.
