Question 1 See full question After assessing a client's family history, the nurse determines the need for a genetic referral based on which of the following? Correct response: Several relatives diagnosed with colon cancer Explanation: A genetic referral would be appropriate when the family history reveals several relatives who have been diagnosed with colon cancer because of the associated possible genetic involvement. A history of two or more unexplained miscarriages as well as consanguinity would be appropriate indications for a genetic referral. If the client has problems with unexplained infertility, then this may be an appropriate reason for a genetic referral. However, a sister's infertility due to the spouse's low sperm count would not be an appropriate indication. Question 2 See full question A newborn has been diagnosed with cleft lip and cleft palate. The parents ask, "How did this happen?" The nurse would incorporate an understanding of which of the following when responding to the parents? Correct response: The conditions result from multiple gene mutations and environmental influences. Explanation: Conditions such as cleft lip and cleft palate result from multiple gene mutations and environmental influences. A recessive gene is not involved. Conditions involving autosomal-dominant inheritance can appear to skip a generation, illustrating incomplete penetrance. These conditions are not the result of X-linked recessive inheritance, so the mother would not be a carrier. Question 3 See full question The nurse, planning an educational program on cystic fibrosis, should include information explaining that cystic fibrosis is an example of which of the following types of inherited conditions? Correct response: Autosomal recessive Explanation: Cystic fibrosis is an autosomal recessive inherited condition. Huntington’s disease would be an example of an autosomal dominant inherited condition. Hemophilia is an X-linked recessive inherited condition. Cleft lip is a multifactorial inherited condition. Question 4 See full question A patient is receiving targeted therapy for treatment of her stage 2 breast cancer. The nurse explains to the patient that this means that the therapy is matched/based on which of the following? Correct response: Tumor’s genetic signature Explanation: Targeted therapy for cancer is based on the genetic signature of the tumor. The therapy is matched to the specific malfunctioning genes expressed in the tumor or it is matched to inhibit genetic factors that facilitate the cancer’s growth. Question 5 See full question

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
