A client has been diagnosed with allergic rhinitis. Which symptoms would the nurse expect to observe?

(Select All that Apply.)

A) Antihistamines:
Antihistamines are commonly used in the treatment of allergic reactions, including anaphylaxis. They work by blocking the effects of histamine, which is released during an allergic reaction, and can help alleviate symptoms such as itching, hives, and nasal congestion. Antihistamines are typically included in the treatment regimen for anaphylaxis but should not be relied upon as the sole treatment.

B) Vasodilators.
Vasodilators are medications that widen blood vessels, leading to a decrease in blood pressure. In the context of anaphylaxis, where blood pressure can drop precipitously due to systemic vasodilation, the use of vasodilators can exacerbate hypotension, potentially worsening the patient's condition. Therefore, vasodilators should be avoided in the management of anaphylaxis.

C) Corticosteroids:
Corticosteroids, such as prednisone or methylprednisolone, are used in the management of anaphylaxis to reduce inflammation and prevent late-phase allergic reactions. They are not typically used as first-line treatment during the acute phase of anaphylaxis but may be administered after initial stabilization to prevent recurrence of symptoms.

D) Bronchodilators:
Bronchodilators, such as albuterol, are used to relieve bronchospasm and improve airflow in conditions such as asthma and chronic obstructive pulmonary disease (COPD). While bronchospasm can occur during anaphylaxis, bronchodilators may still be used to address this symptom. However, they should be used cautiously, and their administration should not delay the administration of epinephrine, which is the primary treatment for anaphylaxis.

A. This is normal.
Guaifenesin is an expectorant medication commonly used to help loosen and thin mucus in the airways, making it easier to cough up. Coughing up phlegm after taking guaifenesin is a typical and expected response to the medication. Therefore, reassuring the client that this is a normal effect of the medication is appropriate.

B. This requires further investigation: Coughing up phlegm after taking guaifenesin is a common and expected outcome, so further investigation is not necessary unless there are other concerning symptoms or indications.

C. This is indicative of an allergic reaction: Coughing up phlegm after taking guaifenesin is not indicative of an allergic reaction. Allergic reactions to guaifenesin are rare and typically present with more severe symptoms such as rash, itching, swelling, or difficulty breathing.

D. This means there is probably more pathology present: Coughing up phlegm after taking guaifenesin does not necessarily indicate the presence of additional pathology. Guaifenesin is intended to help clear mucus from the airways and is commonly used in the treatment of respiratory conditions associated with excess mucus production, such as cough due to cold or bronchitis.
