NAECB Immunotherapy & Allergen Management Flashcards

A grade 3 systemic reaction during SCIT is characterized by:

Answer: Bronchospasm, stridor, or hypotension requiring epinephrine

A grade 3 systemic reaction involves bronchospasm, laryngeal edema, or hypotension and mandates immediate epinephrine administration.

The first-line treatment for a systemic anaphylactic reaction following an immunotherapy injection is:

Answer: Epinephrine 0.3–0.5 mg IM into the lateral thigh

Intramuscular epinephrine 0.3–0.5 mg injected into the anterolateral thigh is the first-line and life-saving treatment for anaphylaxis.

Which allergen sensitization pattern in a US asthma patient most strongly supports initiating immunotherapy?

Answer: Perennial aeroallergen sensitization (dust mite, cockroach) with year-round symptom burden

Perennial aeroallergen sensitization causing year-round asthma and rhinitis symptoms provides the strongest indication for immunotherapy.

Before administering a scheduled SCIT injection, the asthma educator or nurse should verify that the patient's peak flow is:

Answer: At or above 80% of personal best

Peak flow should be at or above 80% of personal best before administering SCIT to ensure the patient is not in a compromised respiratory state that increases reaction risk.

House dust mite (HDM) allergen avoidance measures recommended for sensitized asthma patients include:

Answer: Encasing mattresses and pillows in allergen-impermeable covers and washing bedding in hot water weekly

Allergen-impermeable mattress/pillow encasings and weekly hot-water washing of bedding significantly reduce HDM allergen exposure in sensitized patients.

Cockroach allergen sensitization is particularly prevalent among which US patient population?

Answer: Inner-city, low-income urban residents

Cockroach allergen sensitization disproportionately affects inner-city, low-income urban children and adults due to housing conditions that favor cockroach infestation.
