Explanation

The correct schedule for the three primary doses of the Pentavalent vaccine under India's National Immunization Schedule (NIS) is at 6, 10, and 14 weeks of age.
This vaccine is a cornerstone of the Universal Immunization Programme (UIP), providing combined protection against five critical childhood diseases: Diphtheria, Pertussis, Tetanus (DPT), Hepatitis B, and Haemophilus influenzae type b (Hib).
Administering the doses at these specific intervals is crucial for developing a robust and timely immune response in infants before they are likely to be exposed to these pathogens.

Option A: The schedule of 4, 8, and 12 weeks is not the standard for the Pentavalent vaccine in the Indian National Immunization Schedule.
Option B: The schedule of 5, 10, and 15 weeks is incorrect. The intervals and starting week do not align with the recommended guidelines.
Option D: While the first two doses might seem plausible, the 16-week mark is incorrect for the third dose of the Pentavalent vaccine. The correct interval is 4 weeks between doses.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain National Immunization Schedule (NIS) for the Pentavalent vaccine as background academic context rather than a clinical decision trigger.
Adherence to the national immunization schedule is a critical nursing responsibility to ensure effective public health outcomes and prevent outbreaks of vaccine-preventable diseases.
Nurses play a vital role in educating caregivers about the importance of timely vaccination, managing vaccine inventory, maintaining the cold chain, and documenting administration accurately.
What if an infant presents at 12 weeks for their second dose, having missed the 10-week appointment? The nurse should administer the second dose immediately ('catch-up' vaccination) and schedule the third dose for 4 weeks later (at 16 weeks of age). The schedule should be resumed, not restarted.

How to Approach the Question

Identify the keyword in the question: 'Pentavalent vaccine'.
Recognize that the question is asking for a specific fact: the timing of its administration.
This is a direct recall question based on the National Immunization Schedule (NIS) of India.
Mentally review the key milestones for infant vaccinations: birth, 6 weeks, 10 weeks, 14 weeks, 9 months, etc.
Evaluate the given options against the standard schedule. The combination of 6, 10, and 14 weeks is the well-established timing for several primary infant vaccines, including Pentavalent.
Select the option that correctly matches this established schedule.
