💉 Drug Administration in an Unconscious Patient

✅ Answer: (d) Parenteral Route

📖 What is the Parenteral Route?

Par = Outside
Enteral = Intestine (gastrointestinal tract)

👉 The parenteral route means administering medications outside the digestive tract, usually by injection.

Common parenteral routes include:

• Intravenous (IV)
• Intramuscular (IM)
• Subcutaneous (SC)
• Intradermal (ID)

🩺 Why is it Preferred for an Unconscious Patient?

An unconscious patient cannot swallow safely because protective airway reflexes are reduced or absent.

Using the parenteral route:

• Provides rapid drug action
• Avoids the risk of aspiration
• Ensures accurate drug delivery
• Does not depend on gastrointestinal absorption

👉 Therefore, the parenteral route is the safest and most effective choice.

❌ Why Other Options Are Wrong?

(a) Inhalation Route
❌ Used only for specific medications (e.g., bronchodilators, anesthetic gases) and is not the general preferred route for unconscious patients.

(b) Enteral Route
❌ Involves the gastrointestinal tract (oral, gastric tube, etc.) and is generally avoided unless a feeding tube is already in place.

(c) Oral Route
❌ Contraindicated in unconscious patients because of the high risk of choking and aspiration.

📝 Common Routes of Drug Administration

📌 Exam Tip: In unconscious patients, the oral route is contraindicated because of aspiration risk. The intravenous (IV) route, a type of parenteral administration, is most commonly preferred for rapid and reliable drug delivery in emergencies.
