Hondros 205 Exam 3 (2026 Updated)
Includes verified questions, correct
answers, and rationales covering all key
Nursing 205 topics
Ischemia -CORRECTANSWER inadequate blood supply to organ or other parts of the
body
Hypoxia -CORRECTANSWER Low oxygen saturation of the body, not enough oxygen
in the blood
hypoxemia -CORRECTANSWER deficient amount of oxygen in the blood
Perfusion -CORRECTANSWER The supply of oxygen to and removal of wastes from
the cells and tissues of the body as a result of the flow of blood through the capillaries.
Why are newborns at risk for gas exchange deficiencies -CORRECTANSWER
Reduced lung capacity and increased lung compliance
Why are children at risk for gas exchange impairment -CORRECTANSWER Decreased
alveolar surface and increased exposure to respiratory pathogens
,Why are older adults at risk for gas exchange impairment -CORRECTANSWER Chest
wall increase in stiffness
Loss of elastic recoil
Less tidal volume capacity
What is a barreled chest? -CORRECTANSWER Barrel chest is a visible symptom of
COPD, emphysema, osteoarthritis, and CF
What is an ABG test? -CORRECTANSWER arterial blood gas test
endoscopy/bronchoscopy -CORRECTANSWER Bronchoscopy is a procedure to look
directly at the airways in the lungs using a thin, lighted tube (bronchoscope)
Examples of primary prevention for gas exchange impairment -CORRECTANSWER
Infection Control
Smoking Cessation
Immunizations
Preventing postoperative complications(DVT, Pneumonia)
Examples of Secondary prevention for gas exchange impairment -CORRECTANSWER
TB skin test
,Collaborative Interventions for impaired gas exchange -CORRECTANSWER
Pharmacotherpy - Albuterol, steroid inhalers
Oxygen Therapy - Limit to 2 Liters unless ordered
Chest Physiotherapy
Postural Drainage - Position changes
Invasive Procedures - Chest tubes, thoracentesis
Nutrition
What is asthma? -CORRECTANSWER Constricting of the airway due to inflammation
and muscular contraction of the bronchioles. Also called Reactive Airway Disease
What is COPD? -CORRECTANSWER Chronic Obstructive Pulmonary Disease.
Irreversible decrease in the ability to force air out of the lungs.
Symptoms of COPD -CORRECTANSWER History of progressive shortness of breath,
excessive cough, and sputum production.
Patients with predominantly emphysematous COPD may have dry cough, weight loss,
tachycardia, hypertension
What is pneumonia? -CORRECTANSWER infection of lungs where theres fluid or pus
in the alveoli; poor gas exchange
, What is anemia? -CORRECTANSWER a decrease in the oxygen-carrying
ability(hemoglobin) of the blood or low RBC count
What is a pulmonary embolism? -CORRECTANSWER clot dislodged from peripheral
venous system into pulmonary arterial system. S/S: dyspnea, sudden chest pain,
tachycardia, low BP, tachypnea, low O2 saturation, cyanosis. Treatment: oxygen, semi-
fowlers position, fluids, monitor vital signs often, ECG, ABG, Heparin, cardiopulmonary
support.
What is the blood PH? -CORRECTANSWER 7.35-7.45
What is acidic blood PH? -CORRECTANSWER Below 7.35
What is alkalotic blood PH? -CORRECTANSWER Above 7.45
What would increased diarrhea do to body PH? -CORRECTANSWER Acidosis
What would increased vomitting do to body PH? -CORRECTANSWER Alkalosis
Normal Range of PCO2 in blood -CORRECTANSWER 35-45 mmHg
Normal range:
HCO3-
