Explanation

The Pentavalent vaccine is a 5-in-1 combination vaccine, as indicated by the prefix 'penta'.
It provides protection against five key diseases: Diphtheria, Pertussis (whooping cough), and Tetanus (DPT), along with Hepatitis B and Haemophilus influenzae type b (Hib).
This combination simplifies the immunization schedule by consolidating multiple vaccines into a single injection.
The vaccine is administered in three primary doses at 6, 10, and 14 weeks of age.

Option A: This option incorrectly includes Typhoid and omits Pertussis. The Typhoid vaccine is separate, and Pertussis is a core component of the Pentavalent vaccine.
Option B: This option incorrectly includes Typhoid. The Typhoid vaccine (like TCV) is not part of the Pentavalent combination vaccine.
Option D: This option is a duplicate of option B and is incorrect for the same reason: it includes Typhoid instead of Haemophilus influenzae type b.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Composition and schedule of the Pentavalent vaccine under the Universal Immunization Programme (UIP) as background academic context rather than a clinical decision trigger.
The introduction of the Pentavalent vaccine into the Universal Immunization Programme (UIP) in India was a major step to improve vaccination coverage and reduce infant mortality.
Nurses play a crucial role in educating parents about the importance of completing the three-dose schedule and managing common side effects like mild fever and local pain with paracetamol and cold compresses.
What if a child comes for vaccination at 12 weeks, having missed the 6 and 10-week doses? The nurse should administer the first dose immediately and schedule the next two doses at a minimum interval of 4 weeks each. The schedule is picked up where it was left off, not restarted.

How to Approach the Question

First, identify the key term in the question: 'Pentavalent vaccine'.
Recall the meaning of the prefix 'penta', which is five. This tells you the vaccine protects against five diseases.
Systematically review the components listed in each option.
Remember the standard DPT combination (Diphtheria, Pertussis, Tetanus) which forms the base for many childhood vaccines.
Eliminate options that include diseases not covered by the standard combination vaccine, such as Typhoid. The Typhoid vaccine is given separately.
Select the option that correctly lists the DPT components plus Hepatitis B and Haemophilus influenzae type b (Hib).
