All of the following are given Intradermally except?

Appeared in: RUHS, Jaipur, M.Sc Nursing Entrance Exam-2021

Explanation

Insulin is administered via the subcutaneous (SC) route, not intradermally.
It is injected into the fatty tissue (subcutis) just below the skin for a slow, steady, and predictable absorption rate.
This absorption profile is crucial for maintaining stable blood glucose levels in patients with diabetes.
Common sites for subcutaneous insulin injection include the abdomen, outer thighs, and the back of the upper arms.

Option B: This is incorrect because the Bacille Calmette-Guérin (BCG) vaccine is a classic example of a substance administered intradermally.
Option C: This is incorrect because the Mantoux test, a type of tuberculin skin test, is administered intradermally to check for tuberculosis exposure.
Option D: This is incorrect because sensitivity test doses for drugs, like penicillin, are given intradermally to detect potential allergic reactions safely.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Routes of parenteral drug administration as background academic context rather than a clinical decision trigger.
Using the correct injection route is fundamental to patient safety and medication efficacy. Administering a drug via the wrong route can lead to incorrect absorption rates, therapeutic failure, or adverse reactions.
A nurse must always verify the prescribed route as part of the 'rights' of medication administration (right patient, drug, dose, route, and time).
What if? If insulin were given intradermally, its absorption would be slow and erratic, leading to poor glycemic control. It would also be painful and could cause local tissue irritation or necrosis.

How to Approach the Question

First, identify the core concept of the question, which is the intradermal route of administration.
The keyword 'except' is crucial; it signals that you must find the option that does NOT follow this route.
Systematically review each option and recall its standard route of administration.
Recall that BCG, Mantoux tests, and allergy tests are all classic examples of intradermal injections.
Identify Insulin as the outlier, which is primarily administered subcutaneously.
Select the option that is the exception to the rule stated in the stem.
