· Clients with asthma should be instructed to avoid asthma attack triggers such as mold,
cold air, pet dander, air pollution, and cigarette smoke.
The nurse reviews the laboratory reports of four clients. Which client would the
nurse suspect as having type I–mediated asthma?
o Client A
o Client B
,o Client C
o Client D
o Client A
· Asthma is a type I or IgE-mediated hypersensitivity reaction. Client A, with IgE
antibodies in the blood, has type 1–mediated asthma. Client B, with no antibodies, may
not have humoral allergy or may have a humoral deficiency. Client C and client D may
have either type II or type III hypersensitivity reactions.
Which type of hypersensitivity may have occurred in the client with elevated
histamine and prostaglandin levels, allergic rhinitis, and asthma?
o Type I
o Type II
o Type III
o Type IV
o Type I
· Type I hypersensitivity reactions (immediate hypersensitivity reactions) involve the
immunoglobulin E (IgE)-mediated release of histamines and other mediators from mast
cells and basophils. Allergic rhinitis and asthma may occur when mediators such as
histamine and prostaglandins are involved as mediators of injury. Type II
hypersensitivity reaction is cytotoxic mediated; it occurs in transfusion reactions. Type
III reactions are immune complex–mediated hypersensitivity reactions such as
rheumatoid arthritis. Type IV hypersensitivity reactions are delayed hypersensitivity
reactions; an example is contact dermatitis.
,A client with asthma is pregnant. Which nursing intervention is advisable to
ensure the safe delivery of the baby?
o Have the client stop taking her medication.
o Advise the client to abort the pregnancy.
o Have the client continue the asthma treatment.
o Have the client reduce the dose of the medication.
o Have the client continue the asthma treatment.
· Untreated maternal asthma poses a high risk to the fetus. The client should continue
the medication. The medication should not be stopped because this action may have
harmful effects on both the fetus and the mother. The pregnancy does not need to be
aborted. A reduction in the dose may not give the desired therapeutic action.
The nurse in the health clinic is counseling a college student who recently was
diagnosed with asthma. Which aspect of counseling would the nurse focus on?
o Teaching how to make a room allergy-free
o Referring to a support group for individuals with asthma
o Arranging with the college to ensure a speedy return to classes
o Evaluating whether the necessary lifestyle changes are understood
o Evaluating whether the necessary lifestyle changes are understood
· Understanding the disorder and the details of care are essential for the client to be
self-sufficient. Although teaching is important, a perceived understanding of the need
for specific interventions must be expressed before there is a readiness for learning.
Referring to a support group is premature; this may be done eventually. Although
, ensuring a speedy return to classes is important, involving the college should be the
client’s decision.
Which intervention would the nurse implement for a client admitted for an
exacerbation of asthma?
o Determine the client’s emotional state.
o Give prescribed medications to promote bronchiolar dilation.
o Provide education about the effect of a family history.
o Encourage the client to use an incentive spirometer routinely.
o Give prescribed medications to promote bronchiolar dilation.
· Asthma involves spasms of the bronchi and bronchioles as well as increased
production of mucus; this decreases the size of the lumina, interfering with inhalation
and exhalation. Bronchiolar dilation will reduce airway resistance and improve the
client’s breathing. Although identifying and addressing a client’s emotional state is
important, maintaining airway and breathing are the priority. In addition, emotional
stress is only one of many precipitating factors, such as allergens, temperature
changes, odors, and chemicals. Although recent studies indicate a genetic correlation
along with other factors that may predispose a person to the development of asthma,
exploring this issue is not the priority. The use of an incentive spirometer is not helpful
because of mucosal edema, bronchoconstriction, and secretions, all of which cause
airway obstruction.
The nurse is preparing to discharge a client who presented to the emergency
room for an acute asthma attack. The nurse notes that upon discharge the health
