Question

Address the following items.

1. Define necessary and sufficient conditions. Provide an example from healthcare that articulates the differences.

2. Define inductive versus deductive reasoning. Provide an example from healthcare that articulates the differences.

Answer 1

1.

necessary conditions

A necessary condition is a condition that must be present for an event. eg, if A is necessary for B, B will not occur without A

sufficient conditions

A sufficient condition is a set of conditions that will produce the event. eg, If A is sufficient for B, means if A is there B also will be there.

example:

consider HIV and AIDS

Here, HIV is later converting to AIDS. so, HIV is a necessary condition for AIDS. But, all HIV infected would not develop AIDS. It is not sufficient to cause AIDS.

2.

inductive reasoning

the process of making generalised view by considering some specific instances.it may be a false hypothesis.

example: nurse name 'A' do not like to draw blood. nurse B does not like to draw blood, Also, Nurse C do not like to draw blood. So, all nurses do not like to draw blood. (the statement is false). here, trying to generalise from some cases.

deductive reasoning

the process of making some specific decision from a generalised view.mostly it would be true.

example: A patient said all nurses like to draw blood. (general). you are a nurse and you are going to like to draw blood. (true statement).
