Immunity produced after 1st attack of disease is:

Appeared in: IGNOU PB Bsc Entrance-2022

Explanation

Immunity produced after a natural infection is a type of acquired (or adaptive) immunity.
When the body is exposed to a pathogen from a disease, it actively creates its own antibodies and memory cells.
This specific process is called 'naturally acquired active immunity', which is a major sub-category of acquired immunity.
Therefore, 'Acquired immunity' is the correct broad classification for the immunity gained after a first attack of a disease.

Option B: The term 'Natural immunity' is most commonly used to refer to innate immunity, which is the non-specific defense system a person is born with. It does not develop in response to a specific infection.
Option C: Passive immunity involves receiving pre-formed antibodies from another source, not producing them oneself. The body is not actively involved in creating the immunity.
Option D: Artificial immunity is obtained through deliberate medical intervention, not through a natural disease process.

Clinical Relevance

Nursing practice connection: Safe nursing care depends on performing Types and classification of immunity in the correct sequence, documenting the action clearly, and monitoring for the expected response.
Understanding the different types of immunity is fundamental for nurses to educate patients about vaccinations, infectious diseases, and recovery.
It helps in explaining why vaccines (artificial active immunity) are effective and why some diseases confer lifelong immunity (natural active immunity) while others do not.
A nurse's knowledge of immunity is crucial for implementing infection control measures and managing care for immunocompromised patients.

How to Approach the Question

First, identify the key phrase in the question: 'immunity produced after 1st attack of disease'.
Recognize that an 'attack of disease' is a natural exposure to a pathogen.
Recall the major types of immunity: Innate and Acquired.
Differentiate between them: Innate is inborn and non-specific, while Acquired develops during life and is specific.
Since the immunity is developed after an event, it must be Acquired immunity.
Evaluate the options provided. 'Acquired immunity' is listed and is the correct broad category for immunity developed after an infection.
