Practice
The nurse administers a booster dose of DTaP (diphtheria, tetanus, and pertussis) vaccine to an infant. Which level of prevention is the nurse implementing?
Correct answer
A
Rationale
The correct answer is A: Primary prevention. Administering a booster dose of DTaP vaccine to an infant is an example of primary prevention. Primary prevention aims to prevent disease or injury before it occurs by preventing exposure to risk factors. Tertiary prevention focuses on reducing the impact of a disease or injury that has already occurred, while secondary prevention involves early detection and treatment to prevent the progression of disease. Choice B, tertiary prevention, is incorrect as it deals with managing the consequences of a disease rather than preventing it. Choice C, secondary prevention, is also incorrect as it focuses on early detection and treatment rather than vaccination to prevent the disease. Choice D, primary nursing, is unrelated to the level of prevention being implemented in this scenario.
