The apostrophe is used for possessive nouns and for contractions. In some rare cases, such as letters and numbers, an apostrophe is used with S to create a plural noun.
An apostrophe is used, alone or with an S, to make a noun possessive.Example sentence: Jim's father fixed my bicycle. (the father of Jim)An apostrophe is used to form a contraction, taking the place of some letters left out from one of the joined words.Example sentence: They've finally repaired the potholes. (they have)The same symbol on a keyboard is used for the apostrophe and the single quotation mark.
The apostrophe is generally used to show possession or a contraction. Example 1: "Melissa broke her brother'sskateboard." In this sentence we can see that the apostrophe is used to tell us that the skateboard Melissa broke belongs to her brother. Hence, the apostrophe is used to show possession. Example 2: "Melissa thinks that her brother's a jerk." In this sentence we can see that the apostrophe is used to contract or shorten "brother is." Hence, the apostrophe is used to show a contraction. Other, more common contractions, such as "isn't" (is not) and "don't" (do not) are formed similarly. The best way to decide the proper use of an apostrophe is to know what it is you are writing about. Ask yourself, "Am I writing about a thing that belongs to someone, or am I trying to shorten two words into one?"
It's up to you to decide what to do. The apostrophe is almost never used to form plurals, but rather possessives. The apostrophe is used to indicate a contraction (it is) in the first sentence.
Yes, that is correct because it's is short for it is.
If you mean the apostrophe in the word "patient's," yes, it is used correctly. The hint is the use of the singular possessive, "her," which refers to one patient, thus, "the patient's cardia..."; if the sentence were worded to include a plurality, "are secondary to their thyrotoxicosis," then one should use the plural possessive, "the patients' cardia...". If, however, you mean the apostrophe before the first word in the sentence, no, it is not used correctly: to be correct it requires a closing apostrophe at he conclusion of the sentence.

As written in the question, no. But the apostrophe serves to clarify the function of the word in a sentence. Nests can be used with or without an apostrophe, depending on how the word is used in a sentence. Nests can be a plural noun, or it can be the third personal singular of the verb to nest in the present tense.
I think that the above sentence used in this term, is correctly used in this way.
