Questions
1. 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 ans- -C. Assessing the patient's external ears, nares, and nasal mucosa for
breakdown at least once per shift.
Rationale: Frequent assessment is a priority and will help the nurse identify early signs
of skin breakdown. Although applying lotion is appropriate, this option is not the best
way to maintain good skin integrity. It may not be appropriate to remove the cannula in a
patient for whom oxygen therapy has been ordered. The patient may be unaware of
facial skin areas that are dry or cracking.
What is the best way for the nurse to minimize the risk of contaminating the patient's
eye during the instillation of eye drops?
A. Encourage the patient to self-apply the medication.
B. Wear gloves during the entire application process.
C. Introduce the medication onto the inner canthus of the eye.
,D. Perform effective hand hygiene before and after the instillation. - - correct ans- -B.
Wear gloves during the entire application process.
2. When caring for a patient who is receiving oxygen by simple face mask, which action
ensures that the rate of oxygen being delivered is appropriate?
A. Frequently asking the patient how he or she is breathing.
B. Ensuring that the oxygen tubing is pulled tight, with little or no slack.
C. Securing the oxygen tubing to the patient's clothing to prevent tugging.
D. Assessing for proper placement of the mask on the patient's face. - - correct ans- -D.
Assessing for proper placement of the mask on the patient's face.
Rationale: Monitoring placement of the cannula tips helps ensure that the patient
receives the oxygen prescribed. Asking the patient if he or she is having trouble
breathing does not address oxygen delivery. Oxygen tubing should not be pulled tight.
There should be enough slack in the tubing to allow the patient to turn his or her head
comfortably. Securing the oxygen tubing to keep the patient from pulling out the
cannula does not address oxygen delivery.
Which statement or question best illustrates the nurse's understanding of the role of
nursing assistive personnel (NAP) in the instillation of eye medications?
A. "Did you let the eye medication warm to room temperature?"
B. "Do you think the patient is capable of instilling his own eye drops?"
C. "Be sure to slightly hyperextend her neck when instilling the medication."
D. "Her vision may be temporarily impaired, so please help her to the bathroom." - -
correct ans- -D. "Her vision may be temporarily impaired, so please help her to the
bathroom."
When caring for a patient for whom oxygen by nonrebreathing mask has been ordered,
which action ensures appropriate oxygen delivery?
,A. Looping the oxygen tubing around the side rail of the bed
B. Assessing breath sounds every shift
C. Securing the tubing snugly to the patient's gown
D. Assessing that the reservoir bag stays inflated - - correct ans- -D. Assessing that the
reservoir bag stays inflated
Rationale: A mask that fits properly will deliver the prescribed amount of oxygen. The
oxygen tubing should not be looped around the side rail of the bed. Assessing breath
sounds does not ensure that the oxygen is being delivered appropriately. The tubing
should have some slack so that the patient can move his or her head.
After instructing a patient in the self-administration of antibiotic eye drops, what is the
nurse's highest priority assessment?
A. The patient's understanding of the medication's purpose
B. The patient's hand grasp, strength, coordination, and ability to manipulate the
applicator
C. The patient's comprehension of the dosage instructions provided with the
medication
D. The patient's ability to recognize the signs of an allergic reaction to the medication - -
correct ans- -B. The patient's hand grasp, strength, coordination, and ability to
manipulate the applicator
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 ans- -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
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 ans- -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 ans- -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.
