Urgent Care Urgent Care for Allergic Reactions and Anaphylaxis 3

Question 1

Which of the following is NOT a commonly recognized trigger of anaphylaxis?

Accepted Answer

Vitamin C supplements

Answer

Vitamin C supplements are not a recognized cause of anaphylaxis, whereas NSAIDs, radiocontrast media, and insect venom are all well-documented triggers.

Question 2

What discharge instructions must a patient who experienced anaphylaxis receive from urgent care?

Accepted Answer

Prescription for an epinephrine auto-injector and referral to an allergist

Answer

All patients who experienced anaphylaxis must be discharged with an epinephrine auto-injector prescription and referred to an allergist for allergen identification and immunotherapy evaluation.

Question 3

Why is beta-blocker use an important consideration when treating anaphylaxis?

Accepted Answer

Patients on beta-blockers may have more severe anaphylaxis and be resistant to epinephrine

Answer

Beta-blockers blunt epinephrine's effects on heart rate and bronchodilation and can cause refractory anaphylaxis; glucagon may be needed to overcome the blockade.

Question 4

A patient with anaphylaxis develops hypotension. In addition to epinephrine, what body position is most appropriate?

Accepted Answer

Supine with legs elevated

Answer

Placing the hypotensive anaphylaxis patient supine with legs elevated improves venous return and cardiac output, supporting blood pressure while epinephrine takes effect.

Question 5

What is the primary role of corticosteroids in anaphylaxis management?

Accepted Answer

Adjunctive treatment that may reduce the risk and severity of biphasic reactions

Answer

Corticosteroids act too slowly to treat acute anaphylaxis but are given as adjuncts to potentially blunt late-phase and biphasic reactions over the following hours.
