💥treatment of anaphylaxis

assessment and support of the airway, breathing, and circulation. Epinephrine is usually required, and intramuscular or intravenous diphenhydramine is used secondarily. Late-onset reactions can be prevented with corticosteroids

💥anaphylaxis

Anaphylaxis is an acute IgE-mediated response to an allergen that involves many organ systems and may be life-threatening.

💥Cellular immunity

Antibodies produced by native T-cell lymphocytes

15. A school-aged child, who is allergic to bee stings, states, "I think I was stung by a bee outside." Which intervention by the school nurse is most appropriate? Determine if the client was stung Apply an ice compress to the site Assess the client for signs of anaphylactic shock Administer epinephrine

Assess the client for signs of anaphylactic shock

9. The parents of a 3-month-old infant report concerns the infant is irritable, feeds poorly, and has a rash. The nurse notes weeping, crusty lesions on the infant's cheeks and neck. Which action by the nurse is most appropriate? Advise the parents to change the infant's formula. Instruct the parents to soak the lesions in mineral oil. Contact the health care provider to request treatment. Encourage parents to avoid feeding the infant peanuts.

Contact the health care provider to request treatment

💥common cause of anaphylaxis

In addition to nuts, shellfish, eggs, and bee or wasp stings, drugs such as penicillin and NSAIDs, radiopaque dyes, and latex are the leading causes of anaphylaxis

17. The nurse is caring for a school-age child recently diagnosed with an allergy to peanuts. Which nursing action is a priority? Advise parents the child may benefit from skin testing. Remind parents to report the allergy to the child's school teacher. Include the child when discussing foods that contain peanuts. Offer the parents information about a community support group.

Include the child discussing foods that contain peanuts

4. The parents of an adolescent tell the nurse, "Our child seems to have allergy symptoms every time we visit our favorite cafe. I don't understand since the only allergy indicated in the testing was to eggs?" How should the nurse respond? "Does your child get a whipped cream or foam topping on their favorite drink?" "Maybe the allergy testing didn't evaluate everything your child is allergic to." "That doesn't really make any sense if your child is only allergic to eggs." "Maybe coffee drinks just don't agree with your child's system."

Does your child get whipped cream or foam topping on their favorite drink

💥common food allergens in first years & older children and adults

During the first few years of life, the most common food allergens are milk, eggs, peanuts, tree nuts, fish and shellfish, wheat, and soy. Older children and adults most often demonstrate allergy to peanuts, tree nuts, fish, and shellfish

💥treatment of Severe Combined Immune Disease SCID

IVIG infusions to decrease infections until stem cell transplant

💥treatment of wiskott-aldrich syndrome

IVIG, high-dose steroids, splenectomy to correct thrombocytopenia, stem cell transplant (only cure)

💥food allergy onset & symptoms

Most reactions occur within minutes of exposure, but they may occur up to 2 hours after ingestion. Signs and symptoms of a food allergy reaction include hives, flushing, facial swelling, mouth and throat itching, and runny nose. Many children also have a gastrointestinal reaction, including vomiting, abdominal pain, and diarrhea. In extreme cases, swelling of the tongue, uvula, pharynx, or upper airway may occur. Wheezing can be an ominous sign that the airway is edematous. Rarely, cardiovascular collapse occurs.

20. A pediatric client is newly diagnosed with a stinging-insect allergy. Which advice is mostappropriate for the nurse to provide this client's parent? "I recommend you consult a genetic counselor to reveal other susceptible family members." "Your child should join a peer support group to help relieve anxiety about this problem." "Obtain your child a medical alert ID bracelet so the presence of the allergy can be identified easily." "Arrange for your child to receive allergy testing for foods with ingredients similar to those in insect venom."

Obtain your child a medical alert ID bracelet so the presence of the allergy can be identified easily

2. A nurse is providing education to pregnant women diagnosed with HIV. Which statement indicates the need for further teaching? Pregnancy will accelerate the progression of the disease. My health care provider may want me to have a cesarean birth. Antiretroviral treatment is effective in reducing maternal-fetal transmission. It is not safe to breastfeed my baby, so I will use formula.

Pregnancy will accelerate the progression of the disease FALSE

5. The nurse is explaining patterns of incidence and transmission of HIV to a group of adolescent girls. She explains that the risks for this population are much higher because of the possibility of both vertical and horizontal transmission. Horizontal transmission refers to transmission of the disease during: feeding with breast milk. sexual contact. the birthing process. pregnancy.

Sexual contact

16. The nurse is preparing a care plan for a 4-year-old client newly diagnosed with severe combined immune deficiency. What is the priority goal for this client? The client will return to normal activities after discharge. The client will demonstrate basic knowledge of the disorder. The client will perform hygiene care with assistance. The client will remain free from infection.

The client will remain free from infection

💥body reaction with anaphylaxis

The reaction is severe and usually starts within 5 to 10 minutes of exposure, though delayed reactions are possible. Histamines and secondary mediators are released from the mast cells and eosinophils in response to contact with an allergen. Cutaneous, cardiopulmonary, gastrointestinal, and neurologic symptoms occur. Vasodilation results in a rapid decrease in plasma volume, leading to the risk of circulatory collapse.

Educate the parents about possible side effects of penicillin in children. Encourage the child to wear a medical alert bracelet for penicillin.

Encourage the child to wear a medical alert bracelet for penicillin

6. The parent of a school-age child comments to the nurse, "Every time my child eats enchiladas at our local Mexican restaurant the child gets a rash. It just does not make sense to me." How should the nurse respond? "Has your child ever been tested for a peanut allergy?" "Maybe it is an allergy to something else and you just notice after eating there by coincidence." "That is odd. Does anyone else in your family react that way?" "Is your child allergic to milk?"

Has your child ever been tested for a peanut allergy

10. The nursing instructor has completed a presentation on normal immune function. Which statement by a student would suggest a need for further education? "Humoral immunity is generally functional at birth." "Phagocytosis is the process in which phagocytes swallow up and break down microorganisms." "Cellular immunity is cell-mediated immunity controlled by T cells." "Humoral immunity is immunity mediated by antibodies secreted by B cells."

Humoral immunity is generally functional at birth Humoral immunity, which involves antibodies secreted by B cells, is not fully developed at birth. While some passive immunity is passed from the mother to the infant

If our child does not have a positive rheumatoid factor, our child does not have the disease

18. The nurse has completed an education session with parents of children diagnosed with food allergies. Which statement by a parent would indicate a need for additional education? "The grey part of the EpiPen® should never be removed until right before we use it." "I have found a website that makes medical alert bracelets in my daughter's favorite color." "If we need to use the EpiPen® we will need to notify her physician's office the next business day." "I will make sure my daughter always has her EpiPen® with her all the time."

If we need to use the EpiPen we will need to notify her physician's office the next business day is FALSE
