Pentavalent vaccine provide protection against?

Appeared in: RUHS, Jaipur, PB B.Sc Nursing Entrance-2018

Explanation

The Pentavalent vaccine is a 5-in-1 combination vaccine designed to protect against five different diseases with a single injection.
It contains antigens for Diphtheria, Pertussis (whooping cough), and Tetanus (DPT), along with Hepatitis B (HepB) and Haemophilus influenzae type b (Hib).
This combination simplifies the immunization schedule under the Universal Immunization Programme (UIP), reducing the number of injections a child receives.

Option B: This option incorrectly includes Polio, TB, measles, and mumps.
Option C: This option incorrectly lists Measles, mumps, rubella, and TB.
Option D: This option incorrectly includes Measles, mumps, and rubella, which are the components of the MMR vaccine.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Components and coverage of the Pentavalent vaccine as background academic context rather than a clinical decision trigger.
Nurses play a crucial role in educating parents about the importance of the Pentavalent vaccine in preventing five serious childhood diseases, ensuring adherence to the vaccination schedule (6, 10, 14 weeks).
Proper administration technique (0.5 mL, intramuscularly in the anterolateral aspect of the thigh) is essential to ensure efficacy and minimize local reactions like pain and swelling.
Counseling parents on managing common side effects like fever and irritability, and advising them on when to seek medical help for rare, severe reactions is a key nursing responsibility.

How to Approach the Question

First, identify the core term in the question: 'Pentavalent vaccine'.
Recall the meaning of the prefix 'penta,' which is five. This indicates the vaccine protects against five diseases.
Systematically review your knowledge of the National Immunization Schedule. Recall the components of the Pentavalent vaccine: DPT (Diphtheria, Pertussis, Tetanus) + Hepatitis B + Haemophilus influenzae type b (Hib).
Compare this combination with each of the given options.
Option A perfectly matches these five components.
Eliminate the other options by identifying the incorrect diseases listed, such as Polio, TB, Measles, Mumps, and Rubella, which belong to different vaccines (OPV/IPV, BCG, MMR).
