NURS 441: OXYGENATION STUDY QUESTIONS
(WEEK 1) STUDY GUIDE WITH COMPLETE
SOLUTION!!
Effects of nicotine on blood vessels and lung tissue have been proven to increase
pathological changes, leading to heart disease and lung cancer.
answers: A patient who started smoking in adolescence and continues to smoke 40
years later comes to the clinic. The nurse understands that this patient has an
increased risk for being diagnosed with which disorder:
a. Alcoholism and hypertension
b. Obesity and diabetes
c. Stress-related illnesses
d. Cardiopulmonary disease and lung cancer
ANS: D
Hypoxia occurs because of decreased circulating blood volume, which leads to
decreased oxygen to muscles, causing fatigue, decreased activity tolerance, and a
feeling of shortness of breath.
answers: A patient has been diagnosed with severe iron deficiency anemia. During
physical assessment for which of the following symptoms would the nurse assess
to determine the patient's oxygen status?
a. Increased breathlessness but increased activity tolerance
b. Decreased breathlessness and decreased activity tolerance
c. Increased activity tolerance and decreased breathlessness
d. Decreased activity tolerance and increased breathlessness
ANS: B
,Carbon monoxide strongly binds to hemoglobin, making it unavailable for oxygen
binding and transport.
answers: A patient is admitted to the emergency department with suspected carbon
monoxide poisoning. Even though the patient's color is ruddy, not cyanotic, the
nurse understands that the patient is at a risk for decreased oxygen-carrying
capacity of blood because carbon monoxide does which of the following:
a. Stimulates hyperventilation, causing respiratory alkalosis
b. Forms a strong bond with hemoglobin, creating a functional anemia.
c. Stimulates hypoventilation, causing respiratory acidosis
d. Causes alveoli to overinflate, leading to atelectasis
ANS: A
When the body cannot meet the increased oxygenation need, the increased
metabolic rate causes breakdown of protein and wasting of respiratory muscles,
increasing the work of breathing.
answers: A 6-year-old boy is admitted to the pediatric unit with chills and a fever
of 104°F (40°C). What physiological process explains why the child is at risk for
developing dyspnea?
a. Fever increases metabolic demands, requiring increased oxygen need.
b. Blood glucose stores are depleted, and the cells do not have energy to use
oxygen.
c. Carbon dioxide production increases as result of hyperventilation.
d. Carbon dioxide production decreases as a result of hypoventilation.
ANS: D
,Decreased effective contraction of left side of heart leads to back up of fluid in the
lungs, increasing hydrostatic pressure and causing pulmonary edema, resulting in
crackles in lung bases.
answers: A patient is admitted with the diagnosis of severe left-sided heart failure.
The nurse expects to auscultate which adventitious lung sounds?
a. Sonorous wheezes in the left lower lung
b. Rhonchi midsternum
c. Crackles only in apex of lungs
d. Inspiratory crackles in lung bases
ANS: B
Movement not only mobilizes secretions but helps strengthen respiratory muscles
by impacting the effectiveness of gas exchange processes.
answers: The nurse is caring for a patient who has decreased mobility. Which
intervention is a simple and cost-effective method for reducing the risks of stasis of
pulmonary secretions and decreased chest wall expansion?
a. Antibiotics
b. Frequent change of position
c. Oxygen humidification
d. Chest physiotherapy
ANS: C
Impaired ability to cough up mucus caused by weakness or very thick secretions
indicates a need for suctioning when you know the patient has pneumonia.
, answers: A patient is admitted with severe lobar pneumonia. Which of the
following assessment findings would indicate that the patient needs airway
suctioning?
a. Coughing up thick sputum only occasionally
b. Coughing up thin, watery sputum easily after nebulization
c. Decreased independent ability to cough
d. Lung sounds clear only after coughing
ANS: A
When the lung collapses, the thoracic space fills with air on each inspiration, and
the atmospheric air irritates the parietal pleura, causing pain.
answers: A patient was admitted after a motor vehicle accident with multiple
fractured ribs. Respiratory assessment includes signs/symptoms of secondary
pneumothorax, which includes which of the following?
a. Sharp pleuritic pain that worsens on inspiration
b. Crackles over lung bases of affected lung
c. Tracheal deviation toward the affected lung
d. Increased diaphragmatic excursion on side of rib fractures
ANS: D
Hypoxia is the drive to breathe in a patient with chronic obstructive pulmonary
disease who has become used to acidic pH and elevated CO2 levels. Turning up to
6 L/min increases the oxygen level, which turns off the drive to breathe.
answers: A patient has been newly diagnosed with emphysema. In discussing his
condition with the nurse, which of his statements would indicate a need for further
education?
