Which is a genetic counselor least likely to recommend for a client who has been unable to become pregnant? a. vision testing b. fertility testing c. blood analysis d. family history analysis

Option A, Vision testing

Explanation:

Vision testing has no relevance with the “inability of a patient to get pregnant”. However other test like fertility  test is appropriate in this case as it shall reveal the problems linked to the client’s infertility and on the basis of identified problem the genetic counselor may suggest him/her treatment.

Also the family history analysis will reveal the hierarchical/genetic issues (if any) related to the pregnancy of women in this particular family.

Blood analysis are also assessed for understanding of genetic history of the family .

Thus considering the relevance of test conducted, option A, vision testing is the test which will be least likely recommended by genetic counselor.
