Pentavalent vaccine protects children from which diseases?

Appeared in: NHM UP Staff Nurse - 2016

Explanation

The term 'Pentavalent' signifies protection against five different diseases.
This combination vaccine includes antigens for Diphtheria, Pertussis (whooping cough), Tetanus, Hepatitis B, and Haemophilus influenzae type b (Hib).
It is a cornerstone of the Universal Immunization Programme (UIP) in India, simplifying the schedule by reducing the number of injections.
Since the diseases listed in options A, B, and C are all covered by the vaccine, the most comprehensive and correct choice is 'All of the above'.

Option A: This option is incomplete. While the Pentavalent vaccine does protect against Diphtheria and Tetanus, it also covers three other major diseases.
Option B: This option is incomplete. The vaccine protects against whooping cough (Pertussis), but this option omits the other four diseases covered.
Option C: This option is incomplete. The vaccine covers Hepatitis B and Hib, but it also protects against Diphtheria, Tetanus, and Pertussis.

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 life-threatening diseases with a single injection, which improves compliance with the immunization schedule.
Proper administration technique (0.5 mL, IM, anterolateral thigh) and maintaining the cold chain (2-8°C, do not freeze) are critical nursing responsibilities to ensure vaccine efficacy and safety.
Post-vaccination monitoring for common side effects (fever, local pain) and rare adverse events (seizures, anaphylaxis) is a key patient-safety function for nurses.

How to Approach the Question

First, analyze the keyword 'Pentavalent'. The prefix 'penta-' means five.
Recall or deduce that this is a 5-in-1 combination vaccine.
Review the options to see which diseases are listed.
Option A lists Diphtheria and Tetanus (part of the traditional DTP).
Option B lists Whooping cough (Pertussis, the 'P' in DTP).
Option C lists Hepatitis B and Haemophilus influenzae type b (Hib), the two additional components.
