NR602 I HUMAN CASE WEEK 6 EXAM NEWEST
2025/2026
The nurse has attached the probe of a pulse oximeter to the finger of a
client to monitor oxygen saturation. The nurse notices that the oximeter
reads a low saturation of 88 percent with irregular meter pulsations;
however, upon assessment of the client, the nurse finds no symptoms
of respiratory distress. What might be causing this failure to obtain an
accurate reading? - ANSWER -Peripheral vascular disease.
The nurse is turning on the pulse oximeter and notices a bar form on
the machine. What does this bar represent? - ANSWER -Signal strength.
A nurse takes a client's pulse oximetry reading and finds that it is
normal. What does this finding indicate? - ANSWER -The client's
available hemoglobin is adequately saturated with oxygen.
What would the nurse use to prepare the site for attachment of a pulse
oximeter probe? - ANSWER -An alcohol wipe.
The nurse is using a pulse oximeter to monitor a client who is receiving
oxygen therapy via a nasal cannula. The nurse explains to the client that
which factor might affect the results of pulse oximetry? - ANSWER -
Alterations in circulation.
pg. 1
, The nurse is checking capillary refill to measure circulation in the client's
index finger prior to using a pulse oximeter. What would be the next
best site to place the probe if circulation is found to be inadequate at
this site? - ANSWER -The bridge of the nose.
A nurse must take a client's pulse oximetry reading. The nurse is
explaining the technique to the client. Which statements about pulse
oximetry are true? Select all that apply. - ANSWER -Sensors are
available for use on the finger, toe, foot, earlobe, forehead, and bridge
of the nose.,
Once the oximetry probe is correctly placed, a beam of red and infrared
light travels through the tissue and blood vessels.
The nurse is using a pulse oximeter to measure the oxygen saturation
for a client with lung cancer. Normally, where would the nurse place the
probe of the device? - ANSWER -The index finger.
What assessment would the nurse make prior to using a pulse oximeter
to measure oxygen saturation? - ANSWER -Capillary refill.
The nurse is checking a client's oxygen saturation level using a pulse
oximeter. How should the probe be placed on the finger? - ANSWER -
With the light-emitting sensor and light-receiving sensor opposite each
other.
