This sentence uses the expression 'to knock out' correctly, in the same sense as Kevin uses the expression in this dialogue. 'To be knocked out' before an operation refers to being drugged (using anesthesia or gas for example). Note that the expression indicates 'losing consciousness' or being 'rendered unconscious'.
This sentence uses the expression 'to knock out' incorrectly. Although 'being knocked out' refers to being rendered unconscious, the expression can't be used to describe 'fainting' or 'losing consciousness' as a result of drinking to much. A better choice here is 'pass out': I drank so much that I passed out. Note that a strong cocktail can 'knock you out', but you can't 'knock out on the floor' as the result of drinking too much.
This sentence uses the expression 'to knock out' incorrectly. We knock 'on' or 'at' someone's door, not 'out'. The use of prepositions after the verb 'to knock' changes the meaning of the expression entirely. To knock out (a person): to render unconscious. To knock on, at (a door): to tap on it. To knock up (a girl): to impregnate!
This sentence uses the expression 'to knock out' correctly, meaning to physically render someone unconscious, usually by striking them in the head. Boxers often 'knock each other out' with punches, and their 'knock outs' (or 'K.O.s') are recorded as a measure of their success. This is also the origin of the term 'k.o.' (sometimes used as a verb)! This use of the expression is similar to Kevin's question in the dialogue about 'using anesthetic to knock him out'), however Kevin wants to be rendered unconscious by the use of drugs, and not a punch!
This sentence uses the expression 'to knock out' correctly, meaning to 'eliminate from a competition'. This is a very different use of the expression than in the dialogue, when Kevin is asking to be drugged during the surgery!
