A client in the Emergency Department comes with hypo tension, facial swelling, and urticaria. Which of the following is the best initial management for this client?

1. A

   IV hydrocortisone

2. B

   Give IV fluids

3. C

   Oral antihistamine

4. D

   IM adrenaline

Appeared in: AIIMS M.Sc. Nsg Entrance exam-2026

Explanation

• The client's presentation of hypotension, facial swelling, and urticaria is characteristic of anaphylaxis, a medical emergency.
• Intramuscular (IM) adrenaline (epinephrine) is the first-line, life-saving treatment for anaphylaxis.
• Adrenaline acts rapidly to reverse the life-threatening effects by constricting blood vessels to raise blood pressure, relaxing airway muscles to improve breathing, and reducing swelling.
• Delaying adrenaline administration in anaphylaxis increases the risk of a fatal outcome.

Why Other Options Were Wrong

• Option A: IV hydrocortisone is a corticosteroid with a slow onset of action (several hours). It is not effective for immediate stabilization of life-threatening symptoms.
• Option B: While IV fluids are necessary to treat hypotension in anaphylaxis, they are a supportive measure and not the first-line intervention. Adrenaline must be given first to address the root cause of vasodilation.
• Option C: Oral antihistamines are too slow-acting and only treat cutaneous symptoms like hives and itching. They do not reverse the life-threatening respiratory and cardiovascular collapse seen in anaphylaxis.

Clinical Relevance

• Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Initial Management of Anaphylaxis as background academic context rather than a clinical decision trigger.
• Nurses must be able to rapidly recognize the signs of anaphylaxis and act immediately. The nurse's role includes administering adrenaline promptly as per protocol, calling for help, and continuously monitoring the patient's airway, breathing, circulation, and vital signs.
• Patient safety is paramount. Any delay in administering adrenaline can lead to irreversible airway obstruction, cardiovascular collapse, and death.
• What if the patient is on a beta-blocker? The anaphylactic reaction may be more severe, and the patient may not respond well to adrenaline. In such cases, glucagon may be required as it has inotropic and chronotropic effects on the heart that are not dependent on adrenergic receptors.

How to Approach the Question

• First, analyze the clinical scenario. The patient presents with a constellation of acute symptoms: hypotension (a circulation problem), facial swelling (a potential airway problem), and urticaria (a sign of a systemic allergic reaction).
• Recognize that this combination of symptoms affecting multiple body systems points to a life-threatening condition, which is anaphylaxis.
• Apply the principle of prioritization in emergency medicine. The 'best initial management' must be the intervention that provides the most rapid and effective reversal of the life-threatening process.
• Evaluate the options based on their mechanism and speed of action. Adrenaline (epinephrine) is the only option that rapidly addresses the cardiovascular collapse and airway compromise of anaphylaxis.
• Differentiate between first-line life-saving treatments (adrenaline) and second-line or supportive treatments (corticosteroids, antihistamines, IV fluids). This will lead you to select IM adrenaline as the correct initial action.

Concept Tested & Keywords

• Concept Tested: Initial Management of Anaphylaxis
• Stem keywords: Emergency Department, hypotension, facial swelling, urticaria
• Lead-in keywords: best initial management
• Clinical cues: The combination of hypotension, facial swelling, and urticaria is a classic triad for anaphylaxis, indicating a systemic and severe allergic reaction.
