OXYGENATION AND PERFUSION TEST BANK
2026 VERIFIED ANSWERS GRADED A+
⫸ A nurse is suctioning the nasopharyngeal airway of a patient to
maintain a patent airway. For which condition would the nurse
anticipate the need for a nasal trumpet?
a) The patient vomits during suctioning.
b) The secretions appear to be stomach contents.
c) The catheter touches an unsterile surface.
d) Epistaxis is noted with continued suctioning.. Answer: d) Epistaxis
is noted with continued suctioning.
When epistaxis is noted with continued suctioning, the nurse should
notify the physician and anticipate the need for a nasal trumpet. The
nasal trumpet will protect the nasal mucosa from further trauma
related to suctioning.
⫸ A nurse is inserting an oropharyngeal airway for a patient who
vomits when it is inserted. Which action would be the first that should
be taken by the nurse related to this occurrence?
a) Quickly position the patient on his or her side.
b) Put on disposable gloves and remove the oral airway.
c) Check that the airway is the appropriate size for the patient.
,d) Put on sterile gloves and suction the airway.. Answer: a) Quickly
position the patient on his or her side.
⫸ A nurse is choosing a catheter to use to suction a patient's
endotracheal tube via an open system. On which variable would the
nurse base the size of the catheter to use?
a) The age of the patient
b) The size of the endotracheal tube
c) The type of secretions to be suctioned
d) The height and weight of the patient. Answer: b) The size of the
endotracheal tube
⫸ A nurse is caring for a 16-year-old male patient who has been
hospitalized for an acute asthma exacerbation. Which testing methods
might the nurse use to measure the patient's oxygen saturation? Select
all that apply.
a) Thoracentesis
b) Spirometry
c) Pulse oximetry
d) Peak expiratory flow rate
e) Diffusion capacity
f) Maximal respiratory pressure. Answer: b, c, d
,Spirometers are used to monitor the health status of patients with
respiratory disorders, such as asthma. Pulse oximetry is used to obtain
baseline information about the patient's oxygen saturation level and is
also performed for patients with asthma, along with PEFR to monitor
airflow. These three tests may be administered by the nurse.
⫸ A patient with COPD is unable to perform activities of daily living
(ADLs) without becoming exhausted. Which nursing diagnosis best
describes this alteration in oxygenation as the etiology?
a) Decreased Cardiac Output related to difficulty breathing
b) Impaired Gas Exchange related to use of bronchodilators
c) Fatigue related to impaired oxygen transport system
d) Ineffective Airway Clearance related to fatigue. Answer: c) Fatigue
related to impaired oxygen transport system
⫸ A nurse working in a long-term care facility is providing teaching
to patients with altered oxygenation due to conditions such as asthma
and COPD. Which measures would the nurse recommend? Select all
that apply.
a) Refrain from exercise.
b) Reduce anxiety.
c) Eat meals 1 to 2 hours prior to breathing treatments.
d) Eat a high-protein/high-calorie diet.
e) Maintain a high-Fowler's position when possible.
, f) Drink 2 to 3 pints of clear fluids daily.. Answer: b, d, e
When caring for patients with COPD, it is important to create an
environment that is likely to reduce anxiety and ensure that they eat a
high-protein/high-calorie diet. People with dyspnea and orthopnea are
most comfortable in a high Fowler's position because accessory
muscles can easily be used to promote respiration. Patients with
COPD should pace physical activities and schedule frequent rest
periods to conserve energy. Meals should be eaten 1 to 2 hours after
breathing treatments and exercises, and drinking 2 to 3 quarts (1.9-2.9
L) of clear fluids daily is recommended.
⫸ A nurse is providing postural drainage for a patient with cystic
fibrosis. In which position should the nurse place the patient to drain
the right lobe of the lung?
a) High Fowler's position
b) Left side with pillow under chest wall
c) Lying position/half on abdomen and half on side
d) Trendelenberg position. Answer: b) Left side with pillow under
chest wall
⫸ A nurse is teaching a patient how to use a meter-dosed inhaler for
her asthma. Which comments from the patient assure the nurse that
the teaching has been effective? Select all that apply.
a) "I will be careful not to shake up the canister before using it."
