Chapter 37 : Assessment and Management of Patients With Allergic Disorders Questions
Question 1 of 5
A patient has been admitted to the emergency department with signs of anaphylaxis following a bee sting. The nurse knows that if this is a true allergic reaction the patient will present with what alteration in laboratory values?
Correct Answer: A
Rationale: Higher percentages of eosinophils are considered moderate to severe eosinophilia. Moderate eosinophilia is defined as 15% to 40% eosinophils and is found in patients with allergic disorders. Hypersensitivity does not result in hypoglycemia or increased albumin and neutrophil counts.
Question 2 of 5
A nurse is aware of the need to assess patients risks for anaphylaxis. What health care procedure constitutes the highest risk for anaphylaxis?
Correct Answer: C
Rationale: Radiocontrast agents present a significant threat of anaphylaxis in the hospital setting. Vaccinations less often cause anaphylaxis. Bronchodilators and IV fluids are not implicated in hypersensitivity reactions.
Question 3 of 5
After the completion of testing, a childs allergies have been attributed to her familys cat. When introducing the family to the principles of avoidance therapy, the nurse should promote what action?
Correct Answer: A
Rationale: In avoidance therapy, every attempt is made to remove the allergens that act as precipitating factors. Fully removing the cat from the environment is preferable to just keeping the cat out of the childs bedroom. Avoidance therapy does not involve improving airflow or using antihistamines.
Question 4 of 5
The nurse is providing health education to the parents of a toddler who has been diagnosed with food allergies. What should the nurse teach this family about the childs health problem?
Correct Answer: D
Rationale: Many food allergies disappear with time, particularly in children. About one-third of proven allergies disappear in 1 to 2 years if the patient carefully avoids the offending food. Antihistamines do not cure allergies and an EpiPen is carried, not a steroid inhaler.
Question 5 of 5
A child has been diagnosed with a severe walnut allergy after suffering an anaphylactic reaction. What is a priority for health education?
Correct Answer: B
Rationale: All patients with food allergies, especially seafood and nuts, should have an EpiPen device prescribed. The child does not necessarily need to avoid all common food allergens. Immunotherapy is not indicated in the treatment of childhood food allergies. Immunizations are important, but do not address food allergies.
