Prevention

A client has been taking a decongestant for allergic rhinitis. During a follow-up visit, which finding suggests that the decongestant has been effective? a)Increased tearing b)Headache c)Reduced sneezing d)Increased salivation

Reduced sneezing Explanation: Decongestants relieve congestion and sneezing and reduce labored respirations. When effective, decongestants dry the mucous membranes; therefore, the client shouldn't experience increased salivation or tearing. Because decongestants alleviate congestion, they also relieve headaches, which may be caused by congestion.

A client comes to the clinic reporting nasal congestion and states, "I've been using an over-the-counter nasal spray that seemed to help at first, but then I got even more congested than before I started the medication. I continued the nasal spray, but it seems to be worse." The nurse suspects which of the following? Tolerance to the medication Drug overdose Development of a new allergy Rhinitis medicamentosa

A client presents at the clinic with an allergic disorder. The client asks the nurse what an "allergic disorder" means. What would be the nurse's best response? "It means you are very sensitive to something inside of yourself." "It is a harmless reaction to something in the environment." "It is a muted response to something in the environment." "It is a hyperimmune response to something in the environment that is usually harmless."

"It is a hyperimmune response to something in the environment that is usually harmless."

A patient was seen in the clinic 3 days previously for allergic rhinitis and was given a prescription for a corticosteroid nasal spray. The patient calls the clinic and tells the nurse that the nasal spray is not working. What is the best response by the nurse? "I am sorry that you are feeling poorly but this is the only medication that will work for your problem." "The full benefit of the medication may take up to 2 weeks to be achieved." "You may be immune to the effects of this medication and will need something else in its place." "You need to come back to the clinic to get a different medication since this one is not working for you."

"The full benefit of the medication may take up to 2 weeks to be achieved."

A client is receiving immunotherapy as part of the treatment plan for an allergic disorder. After administering the therapy, the client states, "I guess I can go home now." Which response by the nurse would be most appropriate? a) "You need to stay about another half-hour so we can make sure you don't have a reaction." b)"It's okay to leave but make sure to call us if you start to feel strange after an hour or so." c) "You must stay here so that you can get another injection of a different substance to which you're allergic." d)"We need to schedule your next appointment first and then you can leave."

"You need to stay about another half-hour so we can make sure you don't have a reaction." Explanation: Although severe systemic reactions are rare, the risk of serious and potentially fatal anaphylaxis exists. Therefore, the client needs to remain in the office or clinic for at least 30 minutes after the injection to be observed for possible systemic symptoms. The client should not be allowed to leave until 30 minutes pass. If more than one allergen is being used, the injections typically occur at the same time.

Which of the following would indicate to the nurse that the outcome has been met? Client demonstrates appropriate coping strategies for dealing with a chronic disorder. Client identifies methods for reducing exposure risk to allergens. Client states the need for coughing and deep breathing. Client reports an absence of symptoms associated with the allergy.

Client identifies methods for reducing exposure risk to allergens. Explanation: 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 with an allergic disorder calls the nurse and asks what treatment is available for allergic disorders. The nurse explains to the client that there is more than one treatment available. What treatments would the nurse tell the client about? Sublingual-swallow immunotherapy (SLIT) Desensitization Sublingual-topical immunotherapy (STIT) Resensitization

Desensitization Explanation: Desensitization is another option. Desensitization is a form of immunotherapy in which a person receives weekly or twice-weekly injections of dilute but increasingly higher concentrations of an allergen without interruption. SLIT is a form of desensitization therapy. Options C and D are distractors for this question.

Histamine

The nurse working in an allergy clinic is preparing to administer skin testing to a patient. Which of the following routes is the safest for the nurse to use to administer the solution? Subcutaneous Intramuscular Intravenous Intradermal

Intradermal Explanation: The intradermal route is the correct route of administration for skin testing and therefore a safe route. Another safe route is epicutaneous. The type of skin testing being performed determines whether the nurse will administer the solution via the epicutaneous or intradermal route.

A patient has had a "stuffy nose" and obtained Afrin nasal spray. What education should the nurse provide to the patient in order to prevent "rebound congestion"? a)Use the medication every 4 hours to prevent congestion from recurring. b)Drink plenty of fluids. c)Be sure to use the Afrin for at least 10 days to ensure the stuffiness is gone. d)Only use the Afrin for 3 to 4 days once every 12 hours.

Only use the Afrin for 3 to 4 days once every 12 hours. Explanation: Adrenergic agents, which are vasoconstrictors of mucosal vessels, are used topically in nasal (Afrin) and ophthalmic (Alphagan P) formulations in addition to the oral route (pseudoephedrine [Sudafed]) (Karch, 2012). The topical route (drops and sprays) causes fewer side effects than oral administration; however, the use of drops and sprays should be limited to a few days to avoid rebound congestion.
