HEME IMMUNE

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 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.

p. 1061.

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 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 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.

1063.

A woman who is in her third trimester of pregnancy has been experiencing an

exacerbation of iron-deficiency anemia in recent weeks. When providing the

client with nutritional guidelines and meal suggestions, what foods would be

most likely to increase the woman's iron stores?
