Answer to Question 1
Correct Answer: 1,2,3
Rationale 1: Removing or limiting exposure to animal dander will decrease exposure and subsequent allergic symptoms.
Rationale 2: Frequently cleaning surfaces to eliminate and prevent mold will decrease exposure and subsequent allergic symptoms.
Rationale 3: Frequent cleaning is recommended to decrease exposure to dust mites and subsequent allergic symptoms.
Rationale 4: While this would be very helpful, it may not be reasonable for most clients.
Rationale 5: Dust mites can never be totally removed from mattresses, but regularly decreasing their numbers by frequent cleaning will help decrease symptoms. There is no need to buy new mattresses every 2 years.
Global Rationale: Nurses should help patients identify the sources of the allergy and recommend appropriate actions. These may include removing pets from the home environment or limiting their exposure (such as not allowing the pet on furniture); cleaning moldy surfaces; using and routinely cleaning or replacing microfilters on air-conditioning units; and frequent cleaning to remove dust mites from bedding, carpet, or furniture. Although dust mites can never be totally removed from mattresses, regularly decreasing their numbers can help lessen symptoms of allergic rhinitis. Removal of carpet may not be a reasonable solution for many families.
Answer to Question 2
Correct Answer: 1,2,3
Rationale 1: A nonallergic release of histamine can occur with radiographic contrast dye, resulting in allergic symptoms.
Rationale 2: A nonallergic release of histamine can occur with certain drugs, resulting in allergic symptoms.
Rationale 3: A nonallergic release of histamine can occur with plasma expanders used to restore circulating blood volume in hypovolemia, resulting in allergic symptoms.
Rationale 4: The cause of allergic, not nonallergic, rhinitis is prior exposure to an antigen such as pollen.
Rationale 5: The cause of allergic, not nonallergic, rhinitis is prior exposure to an antigen such as animal dander.
Global Rationale: Nonallergic releases of histamine can occur with cell damage, certain drugs, plasma expanders, or radiographic contrast media. Pollens and animal dander are sources of allergic rhinitis.
