The nurse is preparing to administer a medication that has an affinity for H1 receptors. Which medication would the nurse administer? A. Diphenhydramine (Benadryl) B. Omeprazole (Prilosec) C. Cimetidine (Tagamet) D. Ranitidine (Zantac)

A. Diphenhydramine (Benadryl) Certain medications are categorized by their action at these receptors. Diphenhydramine (Benadryl) is an example of an antihistamine, a medication that displays an affinity for H1 receptors. Cimetidine (Tagamet) and ranitidine (Zantac) target H2 receptors to inhibit gastric secretions in peptic ulcer disease.

Preventive health education includes informing patients about the symptoms associated with allergic rhinitis. The nurse is aware that the most common trigger to this respiratory allergic response is: A. Plant pollen. B. Animal dander. C. Dust mites. D. Mold spores.

The nurse is evaluating the plan of care for a client with an allergic disorder who has a nursing diagnosis of deficient knowledge related to measures for allergy control. Which of the following would indicate to the nurse that the outcome has been met? A. Client states the need for coughing and deep breathing. B. Client demonstrates appropriate coping strategies for dealing with a chronic disorder. C. Client identifies methods for reducing exposure risk to allergens. D. Client reports an absence of symptoms associated with the allergy.

C. Client identifies methods for reducing exposure risk to allergens. For the nursing diagnosis of deficient knowledge, the client's ability to identify methods for reducing the risk of allergen exposure indicates that the outcome has been met. The statment about coughing and deep breathing and an absence of symptoms would be appropriate for evaluating the nursing diagnosis of ineffective breathing pattern. Positive coping strategies would be an appropriate outcome for a nursing diagnosis of ineffective coping.

A client develops a facial rash and urticaria after receiving penicillin. Which laboratory value does the nurse expect to be elevated? A. IgA B. IgB C. IgE D. IgG

C. IgE Immunoglobulin E (IgE) is involved with an allergic reaction. IgA combines with antigens and activates complement. IgB coats the surface of B lymphocytes. IgG is the principal immunoglobulin formed in response to most infectious agents.
