A nurse assessing a client's respiratory status gets a weak signal from the
pulse oximeter. The client's other vital signs are within reference ranges.
What is the nurse's best action?
A. Shine available light on the equipment to facilitate accurate reading.
B. Use a blood pressure cuff to increase circulation to the site.
C. Warm the client's hands and try again.
D. Place the probe on the client's earlobe. Ans✓✓✓ C. Warm the client's
hands and try again.
The nurse is caring for a client who has had a percutaneous
tracheostomy (PCT) following a motor vehicle accident and has been
prescribed oxygen. What delivery device will the nurse select that is
most appropriate for this client?
A. face tent
B. tracheostomy collar
C. simple mask
D. nasal cannula Ans✓✓✓ B. tracheostomy collar
A tracheostomy collar delivers oxygen near an artificial opening in the
neck. This is appropriate for a client who has had a PCT. All other
devices are less appropriate for this client.
,A nurse takes a client's pulse oximetry reading and finds that it is
normal. What does this finding indicate?
A.The client's available hemoglobin is adequately saturated with
oxygen.
B. The client's respiratory rate is in the normal range.
C. The client's red blood cell (RBC) count is in the normal range.
D. The client's oxygen demands are being met. Ans✓✓✓ A.The client's
available hemoglobin is adequately saturated with oxygen.
Pulse oximetry is a noninvasive technique that measures the arterial
oxyhemoglobin saturation (SaO2 or SpO2) of arterial blood. This test
measures only the percentage of oxygen carried by the available
hemoglobin. Thus, even a client with a low hemoglobin level could
appear to have a normal SpO2 because most of that hemoglobin is
saturated. However, the client may not have enough oxygen to meet
body needs. A normal pulse oximetry reading does not necessarily
indicate a normal RBC count or heart rate.
Which should the nurse teach the family about caring for a client with
emphysema at home? Select all that apply.
Maintain a smoke-free environment.
Follow health care provider's prescription for oxygen administration.
, Watch for increased wheezing or signs of a flare-up.
Take advantage of pulmonary rehabilitation programs.
Create a long-term caregiving plan.
Even if the person with emphysema is not smoking anymore, the person
may be living in a home where family members still smoke. Family
must understand why it is important to keep tobacco smoke out of the
house. Caregivers need to be ready and know the signs of a flare-up. For
instance, the client may wheeze more, get increasingly short of breath,
cough more than usual, or have more or a change in color of mucus. If
there is a flare-up, the sooner the client can get treatment, the less likely
the client will require hospitalization. It is worthwhile for clients wi

Which teaching about the oxygen analyzer is important for the nurse to
provide to a client using oxygen?
A. It determines whether the client is getting enough oxygen.
B. It prescribes oxygen concentration.
C. It regulates the amount of oxygen received.
