DPT contains all the following, EXCEPT?

Appeared in: ESIC Nursing Officer 2016 (Shift -2)

Explanation

Measles is not a component of the DPT vaccine.
DPT is a trivalent combination vaccine that specifically protects against three bacterial diseases: Diphtheria, Pertussis (Whooping Cough), and Tetanus.
Protection against measles, which is a viral disease, is provided by a separate vaccine, typically the MMR (Measles, Mumps, Rubella) vaccine.

Option A: This is incorrect because Diphtheria is the 'D' component in the DPT vaccine.
Option B: This is incorrect because Pertussis (whooping cough) is the 'P' component in the DPT vaccine.
Option C: This is incorrect because Tetanus is the 'T' component in the DPT vaccine.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Components of combination vaccines (DPT) as background academic context rather than a clinical decision trigger.
Nurses must know the exact components of combination vaccines to ensure correct administration, prevent medication errors, and provide accurate health education to parents.
Understanding vaccine components is crucial for managing inventory and for correctly documenting which diseases a child has been immunized against.
What if a parent asks if their child is now protected from measles after receiving the DPT shot? The nurse must clarify that DPT does not cover measles and explain the schedule for the separate MMR vaccine to ensure the child is fully protected according to the national schedule.

How to Approach the Question

First, identify the keyword 'EXCEPT'. This indicates you are looking for the option that does not fit with the others.
Next, recall the full form of the acronym DPT, which is a common vaccine.
DPT stands for Diphtheria, Pertussis, and Tetanus.
Compare the options to the components of the DPT vaccine. Diphtheria, Pertussis, and Tetanus are all parts of the vaccine.
The option that is not a component of DPT is 'Measles'. Therefore, it is the correct answer to this 'EXCEPT' question.
