HEME IMMUNE - correct answer ✔✔HEME IMMUNE
An office worker takes a cookie that contains peanut butter. The worker begins
wheezing, with an inspiratory stridor and air hunger and the occupational health
nurse is called to the office. The nurse should recognize that the worker is likely
suffering from which type of hypersensitivity?
Cytotoxic (type II)
Immune complex (type III)
Delayed-type (type IV)
Anaphylactic (type 1) - correct answer ✔✔Correct response:
Anaphylactic (type 1)
Explanation:
The most severe form of a hypersensitivity reaction is anaphylaxis. An
unanticipated severe allergic reaction that is often explosive in onset, anaphylaxis
is characterized by edema in many tissues, including the larynx, and is often
accompanied by hypotension, bronchospasm, and cardiovascular collapse in
,severe cases. Type II, or cytotoxic, hypersensitivity occurs when the system
mistakenly identifies a normal constituent of the body as foreign. Immune
complex (type III) hypersensitivity involves immune complexes formed when
antigens bind to antibodies. Type III is associated with systemic lupus
erythematosus, rheumatoid arthritis, certain types of nephritis, and bacterial
endocarditis. Delayed-type (type IV), also known as cellular hypersensitivity,
occurs 24 to 72 hours after exposure to an allergen.

A client comes to the clinic reporting fatigue and the health interview is suggestive
of pica. Laboratory findings reveal a low serum iron level and a low ferritin level.
With what would the nurse suspect that the client will be diagnosed?
Iron deficiency anemia
Hemolytic anemia
Sickle cell disease
Pernicious anemia - correct answer ✔✔Correct response:
Iron deficiency anemia
Explanation:
,A low serum iron level, a low ferritin level, and symptoms of pica are associated
with iron deficiency anemia. TIBC may also be elevated. None of the other
anemias are associated with pica.

A client who is scheduled for a skin test informs the nurse that he has been taking
corticosteroids to help control his allergy symptoms. What nursing intervention
should the nurse implement?
The client should only be tested for grass, mold, and dust initially.
The client should take his corticosteroids regularly prior to testing.
The client's test should be cancelled until he is off his corticosteroids.
The nurse should have an emergency cart available in case of anaphylaxis during
the test. - correct answer ✔✔Correct response:
The client's test should be cancelled until he is off his corticosteroids.
Explanation:
, Corticosteroids and antihistamines, including over-the-counter (OTC) allergy
medications, suppress skin test reactivity and should be stopped 48 to 96 hours
before testing, depending on the duration of their activity. Emergency equipment
must be at hand during allergy testing, but the test would be postponed.
