Correct Answers)
1) In a client with a tracheostomy, the nurse should monitor for complications
related to the loss of which protective mechanism?
A) Filtration and humidification of inspired air
B) The ability to cough
C) Decrease in oxygen-carrying capacity of the trachea
D) The sneeze reflex initiated by irritants in the nasal passages
Ans: Answer: A
Explanation: A) When the nasal passages are bypassed, as they would be in the case
of a client with a tracheostomy, the filtration, humidification, and warming of the
nasal passages are also bypassed. The client can still cough and sneeze, and there is
no decrease in the oxygen-carrying capacity of the trachea.
B) When the nasal passages are bypassed, as they would be in the case of a client
with a tracheostomy, the filtration, humidification, and warming of the nasal
passages are also bypassed. The client can still cough and sneeze, and there is no
decrease in the oxygen-carrying capacity of the trachea.

D) Exposure to second-hand smoke
E) Nutritional status
Ans: Answer: C, D
Explanation: A) The nurse should assess the client for exposure to airborne
pollutants and secondhand smoke. A number of factors affect a healthy respiratory
system. The air an individual breathes, either indoors or outdoors, may be polluted.
Exposure to airborne irritants may produce an inflammatory response within the
airways. Assessing the client's participation in recreational activities and nutritional
status is important
3) A firefighter has been admitted to the ED. He has no visible burn injuries. He is
somewhat inattentive and uncoordinated and is frequently attempting to get off the
gurney and leave the ED. What might the nurse hypothesize about his condition?
Select all that apply.
A) The firefighter is exhibiting normal anxiety after a traumatic event and is ready
for discharge.
B) The firefighter is showing signs of mild cerebral hypoxia related to smoke
inhalation.
C) The firefighter has severe cerebral hypoxia.
D) The firefighter is suffering from ARDS.
E) Further tests are indicated to determine the extent of the problem.
Ans: Answer: B, E
Explanation: Symptoms of mild cerebral hypoxia include change in attention, poor
judgment, and uncoordinated movement. Symptoms of severe cerebral hypoxia
include complete unawareness and unresponsiveness, no breathing, and no response
of the pupils of the eye to light. ARDS is a severe form of acute respiratory failure.
Inattention and lack of coordination are not anxiety-related symptoms. X-rays and
blood tests may be used to further assess the problem.
4) What therapies may the nurse expect to provide to a client with asthma?
Select all that apply.
A) Ventilatory support
B) Oral and nasal suctioning
C) Instruction on aggravating factors
