Final answer:
It is important to avoid allergy medications such as antihistamines before allergy tests to prevent false-negative results. Montelukast, used to treat asthma, may contain aspirin derivatives, so when administering montelukast, the nurse should check for aspirin allergies and consult with the healthcare provider as needed.
Step-by-step explanation:
Critical Thinking on Allergy Medications and Testing
It is important to avoid allergy medications before undergoing allergy testing because these medications can suppress the immune response to allergens, potentially leading to false-negative results. Allergens are typically nonpathogenic, and reactions to them can range from mild, treated with antihistamines, to severe cases like anaphylactic shock, which may necessitate epinephrine administration. Following an allergic reaction, patients are usually treated with antihistamines and slow-acting corticosteroids. Patients are encouraged to carry epinephrine injectors, especially when access to hospitals is limited
In response to inhaled allergens, mast cell degranulation occurs, leading to immediate hypersensitivity reactions characterized by symptoms such as nasal edema and runny nose. Treatment for milder allergies typically includes antihistamines, antileukotriene, and antiprostaglandin drugs, often used in combination for a more effective therapy regime.
Regarding the nurse's question about administering montelukast, the correct action is to check for allergies to aspirin and notify the healthcare provider, because montelukast may contain aspirin derivatives that could cause a severe allergic reaction. Allergies to cellulose, lactose, zolpidem, xylitol, and ampicillin are not directly related to montelukast administration.
