Convenience sampling refers to a non-quality control of individuals that are used for studies. From a nursing standpoint it can limit the accuracy of findings as well as prevent certain aspects from being discovered. By excluding certain variables from a test, the results will not be accurate meaning that they can not be transferred to real-world applications effectively.
You are correct; convenience sampling is not random sampling.
The difference between convenience and incidental sampling is that convenience sampling chooses the easiest people to reach when a sampling is done, whereas incidental sampling is done at random.
Convenience sampling or quota sampling
No. Convenience sampling involves the active participation of the researcher. It's called convenience sampling because the researcher simply grabs whomever happens to be close to hand. It's not whether people volunteer themselves. Please see the link.

Simple Random Sample Stratified Random Sampling Cluster Sampling Systematic Sampling Convenience Sampling
convenience sampling consists of two or more sample events.
It is a form of nonrandom sampling. In essence it means obtaining observations that are easiest to get. For example, asking your friends how they plan to vote would be a political poll based on a convenience sample. Many types of formal, probability statistics are meaningless when convenience sampling is done. The researcher cannot claim to "generalize" their findings to any particular population. You probably could not accurately (i.e., within a couple percentage points) predict an election result based only on what your friends say. Therefore most typical statistical studies would avoid convenience sampling. It may be very useful for qualitative studies, but less so for quantitative work.

Standing in a shooping mall and selecting people as they walk by to fill out a survey is an example of convenient sampling.
