Which of the following patients would have the greatest potential for an
alteration in respiration?
A.) 15 year-old male with a migraine headache.
B.) 44 year-old female with anemia.
C.) 19 year-old female with diarrhea.
D.) 32 year-old male with an ear ache. - ANSWER✔✔ B
REASON: Hemoglobin carries about 97% of oxygen to the tissues. Anemia lowers
the oxygen-carrying capacity of the blood and potentially leads to hypoxia.
Which of the following, if exhibited by the patient, would indicate late hypoxia?
A.) Restlessness
B.) Anxiety
C.) Eupnea
D.) Cyanosis - ANSWER✔✔ D
REASON: Restlessness and anxiety are early indicators of hypoxia. Cyanosis is a
late indicator of hypoxia. Eupnea is normal respiration.
Which of the following would lead to an increase in oxygen demand?
A.) A fever
, B.) Sleep
C.) Taking a narcotic
D.) Postural drainage - ANSWER✔✔ A
REASON: Increased metabolic activity associated with a fever increases tissue
oxygen demand. Postural drainage is an intervention used to mobilize secretions
and maintain an open airway.

sputum?
A.) Perform nasotracheal suctioning every hour
B.) Encourage the patient to cough every hour while awake

D.) Avoid all milk products - ANSWER✔✔ B
REASON: A patient with a large amount of sputum should be encouraged to cough
every hour while awake. Suctioning should be performed on an as-needed basis.
Adequate fluids should be maintained to help keep secretions thin and easy to
expectorate. Although milk has a protein structure similar to sputum, it does not
increase sputum production and plays an important role in nutrition.
An elderly woman is hospitalized with pneumonia and anemia. She is weak and
has a poor cough effort. She has a history of cardiomyopathy. Her current vital
signs are temperature 100.2 °F, pulse 114, respiration 26, blood pressure 106/58.
She has oxygen ordered at 2 liters by nasal cannula. Her oxygen saturation
measures 88% when on room air, 93% with supplemental oxygen. She develops
shortness of breath on any activity and eats little because it is difficult for her to
