RATIONALES
When caring for a patient who is receiving supplemental oxygen by face tent, which action
ensures that the oxygen is flowing?
A. Testing the closing capacity of the mask's valves
B. Routinely monitoring the seal over the patient's mouth and nose
C. Ensuring that a mist is always present
D. Regularly verifying that the mask is positioned loosely --CORRECT ANSWER--C.
Ensuring that a mist is always present
Rationale: It is appropriate to ensure that a mist is always present when oxygen is delivered
by face tent. Testing the closing capacity of the mask's valves is appropriate only for a
nonrebreathing mask. Monitoring the seal over the patient's mouth and nose is appropriate
only for a nonrebreathing mask. Such an assessment is appropriate, but correct positioning of
the mask does not indicate that oxygen is flowing from it.
When placing an intraocular disk, the nurse recognizes that it is in the correct position by
assessing what?
A. Visibility of the disk over the cornea
Page 1 of 101
,B. Lack of visibility of the disk as it is placed under the lower eyelid
C. Lack of visibility as it is placed under the upper eyelid
D. Visibility of a small portion of the disk extending slightly above the lower eyelid --
CORRECT ANSWER--B. Lack of visibility of the disk as it is placed under the lower eyelid
What would the nurse do when receiving an order to increase the delivery rate of a patient's
oxygen per nasal cannula from 1 L/min to 3 L/min?
A. Encourage the patient to take deeper breaths in order to get more oxygen
B. Change the device from nasal cannula to simple face mask
C. Ensure that humidification is present
D. Adjust the float ball on the flow meter to 3 L/min --CORRECT ANSWER--D. Adjust the
float ball on the flow meter to 3 L/min
Rationale: The nurse would increase the flow rate by moving the ball on the oxygen delivery
system from 1 L/min to 3 L/min. Taking deeper breaths will not change the flow rate from 1
L/min to 3 L/min. There is no need to change the delivery device. The provider has ordered
oxygen to be administered per nasal cannula, not per simple face mask. If the flow rate of
oxygen is 4 L/min or higher, humidification is added. Oxygen delivered at the rate of 3 L/min
need not be humidified.
Which instruction should be given to a patient to ensure safety when self-applying an
antibiotic ointment?
A. It is not necessary to allow refrigerated eye medication to warm to room temperature
before administration.
Page 2 of 101
,B. Do not apply pressure directly to the eyeball when removing excess medication.
C. When cleaning the eye before administration, gently wash from the outer to the inner
canthus.
D. Apply a warm, damp washcloth to the eye for several minutes to remove any crusted
discharge. --CORRECT ANSWER--B. Do not apply pressure directly to the eyeball when
removing excess medication.
A patient who had surgery yesterday has the initial dressing covering the surgical site. What
is the nurse's responsibility in assessing this patient's wound?
A. Remove the dressing, inspect the wound, and reapply a new dressing.
B. Inspect the wound and reapply the surgical dressing every 2 hours.
C. Inspect the wound, and keep the dressing off until the health care provider arrives.
D. Wait until the health care provider orders the removal of the surgical dressing. --
CORRECT ANSWER--D. Wait until the health care provider orders the removal of the
surgical dressing.
Rationale: The nurse would want to wait until the provider orders the dressing to be removed
to ensure that the initial dressing is ready to come off. The nurse would not remove an initial
surgical dressing for direct wound inspection until the health care provider has written an
order for its removal.
What is the best way to minimize discomfort caused by the instillation of ear medication?
A. Warm the eardrops to room temperature before instillation.
B. Wear treatment gloves during the application process.
C. Ask the patient to sit while introducing the medication.

, D. Use a cotton-tipped applicator to remove any visible cerumen. --CORRECT ANSWER--
A. Warm the eardrops to room temperature before instillation.
Which instruction would help ensure the maximum therapeutic response when a patient self-
administers ear medication?
A. Remain in the lateral position (unaffected side) for a few minutes after instillation.
B. Bring refrigerated ear medication to room temperature before instillation.
C. Place a cotton ball firmly into the ear canal for 30 minutes after instillation.
D. Apply a warm, damp washcloth to the external ear to remove any crusted discharge. --
CORRECT ANSWER--A. Remain in the lateral position (unaffected side) for a few minutes
after instillation.
When caring for a patient receiving oxygen by nasal cannula, which of the following is a
priority to help maintain good skin integrity?
A. Frequently applying moisturizing lotion to facial areas that come into contact with the
cannula.
B. Removing the cannula every 2 hours for no longer than 10 minutes.
C. Assessing the patient's external ears, nares, and nasal mucosa for breakdown at least once
per shift.
D. Instructing the patient to inform staff of any problems with facial dryness or cracking. --
CORRECT ANSWER--C. Assessing the patient's external ears, nares, and nasal mucosa for
breakdown at least once per shift.
