SECTION 1: OXYGENATION & RESPIRATORY CARE
Questions 1-15
Question 1
A patient with chronic obstructive pulmonary disease (COPD) has an oxygen saturation of 88%. The nurse
should:
A) Apply oxygen at 2 L/min via nasal cannula
B) Apply oxygen at 4 L/min via nasal cannula
C) Not apply oxygen because COPD patients are at risk for hypercapnia
D) Apply oxygen as prescribed and monitor for respiratory depression
Correct Answer: D
Rationale: Patients with COPD may have a hypoxic drive to breathe. Oxygen should be administered as
prescribed to maintain SpO2 -92%.
88 The nurse should monitor for respiratory depression, which is indicated
by a decreased respiratory rate and increased2.CO
Low-flow oxygen is appropriate for these patients.
Applying oxygen at -24 L/min is appropriate if prescribed, but the nurse should not apply oxygen without an
order .
Question 2
The nurse is assessing a patient's respiratory status. Which finding indicates inadequate oxygenation?
A) Respiratory rate 18 breaths per minute
B) SpO2 98%
C) Use of accessory muscles
D) Clear breath sounds
Correct Answer: C

NGN-ALIGNED | MULTIPLE-CHOICES | DETAILED RATIONALES - A+ GRADED
Rationale: Use of accessory muscles (sternocleidomastoid, intercostals, abdominal muscles) indicates
increased work of breathing and inadequate oxygenation. This is a sign of respiratory distress. Normal
respiratory rate, SpO2 98%, and clear breath sounds
are all normal findings .
Question 3
A nurse is suctioning a patient with a tracheostomy. What is the maximum time the nurse should suction?
A) 5 seconds
B) 10 seconds
C) 15 seconds
D) 20 seconds
Correct Answer: B
Rationale: The nurse should suction for no more than 10 seconds at a time to prevent hypoxia and tissue
damage. Prolonged suctioning can cause trauma, hypoxia, and vagal stimulation leading to bradycardia. The
nurse should pre
-oxygenate the patient before
suctioning .
Question 4
A patient is on a non
-rebreather mask with the reservoir bag. The bag must be inflated with oxygen before
placing the mask on the patient. This is done to:
A) Prevent carbon dioxide rebreathing
B) Ensure oxygen delivery
C) Prevent aspiration
D) Increase humidity
Correct Answer: B

NURSING I | GALEN COLLEGE OF NURSING | MOST TESTED | 100 VERIFIED Q&A |
NGN-ALIGNED | MULTIPLE-CHOICES | DETAILED RATIONALES - A+ GRADED
Rationale: The reservoir bag must be inflated with oxygen before applying the mask to ensure that the patient
receives oxygen immediately. A deflated bag indicates the oxygen flow is insufficient, and the patient may
rebreathe carbon dioxide. The bag shoul
d be kept inflated during use. If the bag deflates, the patient is not
receiving enough oxygen .
Question 5
A patient is using an incentive spirometer. Which is the correct technique?
A) Inhale slowly and deeply, holding the breath for
-5 seconds
3
B) Exhale forcefully into the spirometer
C) Inhale quickly through the mouth
D) Inhale while sitting upright
Correct Answer: A
Rationale: The patient should inhale slowly and deeply through the mouthpiece, holding the breath
-5 for 3
seconds, then exhale normally. This helps expand the lungs and prevent atelectasis. The patient should use the
spirometer every hour while awake .
Question 6
A patient with pneumonia has a productive cough. The nurse should:
A) Suction the patient
B) Encourage coughing and deep breathing
C) Administer a cough suppressant
D) Position the patient in supine position
Correct Answer: B
