Chapter 34 : Caring for Clients With Immune-Mediated Disorders Questions
Question 1 of 5
A client received 2 units of packed red blood cells while in the hospital with rectal bleeding. Three days after discharge, the client experienced an allergic response and began to itch and break out with hives. What type of reaction does the nurse understand could be occurring?
Correct Answer: A
Rationale: A delayed hypersensitivity response may develop over several hours or days, or it may reach maximum severity after repeated exposure. Examples of a delayed hypersensitivity response include a blood transfusion reaction that occurs days to weeks after blood administration, rejection of transplanted tissues, and reaction to a tuberculin skin test. Anaphylaxis is a rapid and profound type I hypersensitivity response. Sensitization is the process by which cellular and chemical events occur after a second or subsequent exposure to an allergen. An immediate hypersensitivity response is due to antibodies interacting with allergens and occurs rapidly.
Question 2 of 5
A client comes to the clinic to see the physician, reporting, 'I think I ate something that I am allergic to.' What symptoms would be appropriate for the nurse to ask questions about?
Correct Answer: D
Rationale: Clinical manifestations generally correlate with the manner in which the allergen enters the body. Inhaled allergens usually cause respiratory symptoms, including nasal congestion, runny nose, sneezing, coughing, dyspnea, and wheezing. Contactants cause skin reactions such as hives, which appear as vesicles filled with clear fluid surrounded by a margin of redness, rash, and localized itching. Cramping, vomiting, and diarrhea are associated with ingested food allergens. Allergic skin responses may also occur with allergies to foods.
Question 3 of 5
The nurse is talking with a client who was stung by a bee and began having difficulty breathing. What serious complication from injected venom should the nurse discuss with the client?
Correct Answer: C
Rationale: Injectants, such as bee venom, and some other allergens can produce systemic and potentially fatal effects, including shock and airway obstruction caused by laryngeal swelling. Although all other answers can occur with an allergen, they are not the most serious complication.
Question 4 of 5
A client is scheduled to have a prick test to determine what specific allergens are creating problems for the client. What should the nurse inform the client is involved with the testing?
Correct Answer: C
Rationale: The scratch or prick test involves scratching the skin and applying a small amount of the liquid test antigen to the scratch. The tester applies one allergen per scratch over the client's forearm, upper arm, or back. The back is more sensitive than the arm. Results of the test are identifiable in as little as 20 minutes. If a raised wheal with localized erythema appears, the tester measures its length and width in millimeters. The client does not taste in any of the skin tests.
Question 5 of 5
A client informs the nurse of being very allergic to poison ivy but expresses enjoying and having several camping trips planned for the summer months. What suggestions can the nurse make to protect the client against poison ivy?
Correct Answer: B
Rationale:
To protect against poison ivy, clients can apply bentoquatam 5% to the skin 15 minutes prior to exposure and at least every 4 hours as long as risk of exposure continues. The cream forms a protective layer on top of the skin. Calamine lotion can be used for the itching related to poison ivy exposure. Vinegar and water is not an effective way to manage the prevention of poison ivy. Benadryl will not protect against poison ivy.
