Match the following correctly as name of the vaccine column first to route of the vaccine column second?

	Vaccine		Route
A	Measles	1	Oral
B	BCG	2	IM
C	Hib	3	ID
D	OPV (Sabin)	4	SC

1. A

   A-4, B-3, C-2, D-1

2. B

   A-3, B-4, C-1, D-2

3. C

   A-4, B-2, C-3, D-1

4. D

   A-2, B-3, C-4, D-1

Explanation

• The question requires matching each vaccine to its correct route of administration.
• Measles vaccine is administered via the Subcutaneous (SC) route (A-4).
• Bacillus Calmette-Guérin (BCG) vaccine is given through the Intradermal (ID) route (B-3).
• Haemophilus influenzae type b (Hib) vaccine is given via the Intramuscular (IM) route (C-2).
• Oral Polio Vaccine (OPV) is administered Orally (D-1).
• Therefore, the correct combination is A-4, B-3, C-2, D-1.

Why Other Options Were Wrong

• Option B: This option incorrectly matches Measles with Intradermal (ID) and BCG with Subcutaneous (SC). Measles is SC, and BCG is ID.
• Option C: This option incorrectly pairs BCG with Intramuscular (IM) and Hib with Intradermal (ID). BCG is ID, and Hib is IM.
• Option D: This option incorrectly matches Measles with Intramuscular (IM) and Hib with Subcutaneous (SC). Measles is SC, and Hib is IM.

Clinical Relevance

• Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Vaccine Administration Routes as background academic context rather than a clinical decision trigger.
• Administering a vaccine via the wrong route can lead to reduced efficacy or an increased risk of local or systemic adverse reactions. For example, giving BCG subcutaneously instead of intradermally can cause a severe local reaction or abscess.
• Nurses must be proficient in different injection techniques and know the specific requirements for each vaccine to ensure patient safety and optimal immunization outcomes.
• What if? If a live vaccine like measles (SC) were accidentally given intramuscularly, it might still be effective, but it deviates from the manufacturer's and national guidelines. The primary concern is ensuring proper technique for every administration to guarantee the standardized, proven immune response.

How to Approach the Question

• First, identify the core task: matching vaccines to their administration routes.
• Scan the list and identify the easiest or most certain matches. For instance, 'Oral Polio Vaccine' (OPV) directly states its route is 'Oral'. So, D must match with 1.
• Use this confirmed pair (D-1) to eliminate options that do not contain it. All four given options end with D-1, so this doesn't narrow it down this time, but it's a good strategy.
• Next, recall the most unique administration route. BCG is famously given intradermally (ID) to produce a scar. So, B must match with 3.
• Now look for the option that contains both B-3 and D-1. Only option A (A-4, B-3, C-2, D-1) fits this criterion.
• Finally, verify the remaining pairs in the selected option: Measles is Subcutaneous (A-4) and Hib is Intramuscular (C-2). This confirms the entire sequence is correct.
