Which of the following sampling techniques involves selecting the medical record of every fifth patient undergoing cardiovascular bypass?

  1. convenience

  2. simple random

  3. stratified

  4. systematic

The correct answer is: convenience

The other options are not the correct answers for this scenario: - B. simple random sampling involves selecting a random sample from the entire population, not selecting every fifth patient. - C. stratified sampling involves dividing the population into subgroups and then selecting samples from each subgroup, which is not the case in this scenario. - D. systematic sampling involves selecting every nth member from a list, which is the sampling technique described in the question, but it is not the correct answer in this particular case.
