Answers
1. A student nurse is explaining to a pt about the respiratory system. Which
statement by the student nurse would require correction from the clinical
instructor?
a. Neural & chemical regulators control the rate and depth of respiration in
response to changing tissue O2 demands.
b. The respiratory system is the system responsible for supplying O2 to the rest of
the body.
c. The exchange of respiratory gases occurs between the environment and the
blood.
d. Respiration is the exchange of O2 and CO2 during cellular metabolism. correct
answer B: Both the respiratory and cardiac systems are responsible for supplying
O2 to the rest of the body.
1. Which of the following is not a nursing obligation in ethical decisions?
a. Maximize the client's wellbeing.
b. Focus on the family members' responsibilities for the client's wellbeing.
c. Support each family member and enhance family support system.
d. Protect the nurse's own standards of care while carrying out hospital policies.
correct answer B: The nurse should balance the client's need for autonomy with
family members' responsibilities for the client's wellbeing. Other nursing
obligations include protecting other clients' wellbeing.

a. She has an orientation towards service and ethical principles.
,b. She uses evidence-based practice.
c. She adheres to legal requirements.
d. She is part of the ANA.
e. She communicates therapeutically.
f. She is licensed by the American Association of Colleges of Nursing.

the professional nurse include a strong knowledge base, orientation toward
service, adherence to ethical principles, use of evidence-based practice,
adherence to legal requirements, licensed by the STATE BOARD OF NURSING, and
involvement in professional organizations. Communicating therapeutically is good
practice, but not an attribute of professional nursing.
10. A pt presents with polycythemia secondary to anemia. The student nurse
knows that which factor affecting oxygenation is being affected?
a. Decreased inspired O2 concentration
b. Decreased O2 carrying capacity
c. Increase metabolic rate
d. Hypovolemia correct answer B: Decreased O2-carrying capacity is caused by
conditions that affect Hgb, such as anemia and inhaled toxins (CO). Hypovolemia
is a reduced circulatory blood volume caused by shock and dehydration.
Decreased inspired O2 concentration is caused by airway obstruction, less FiO2,
and hypoventilation secondary to drug overdose. Increased metabolic rate
increases O2 demands and is caused by fever, exercise, pregnancy, & wound
healing.
11. Which of the following affect chest wall movement and therefore affect
oxygenation? SATA.
a. Developmental stages
, b. MS
c. Pregnancy
d. Smoking
e. Substance abuse
f. Obesity
g. Rib fractures
h. Workplace
i. Kyphosis correct answer B, C, F, G, & I: Pregnancy, obesity, neuromuscular
disease (MS, ALS), musculoskeletal abnormalities (scoliosis, kyphosis, & lordosis),
trauma (rib fractures, surgical incision, & opioids), and CNS alterations all affect
chest wall movement. Smoking and substance abuse are lifestyle factors that
affect oxygenation. Workplace and urban living are environmental factors that
affect oxygenation. Development also affects oxygenation.
12. Which of the following ages are matched with their correct risk factor that
could affect oxygenation? SATA.
a. SA & adolescents: risk for 2nd hand smoke & cigarette smoking
b. OA: risk for pneumonia & respiratory infection bc of changes in cardiac and
pulmonary systems
c. infants & toddlers: risk for decreased oxygenation as a result from immature
lungs and low surfactant levels
d. YA & MA: cardiopulmonary risk factors & occupational risks correct answer C:
Infants are at risk for decreased oxygenation due to immature lungs and low
surfactant levels. Infants and toddlers are at risk for upper respiratory tract
infections.
