A woman comes to the clinic for a routine checkup. After obtaining the client's history, the nurse identifies that the client is at increased risk for cervical cancer based on her history of exposure to which virus?

A. Hepatitis:

- Hepatitis viruses (such as hepatitis B and hepatitis C) primarily affect the liver and are not directly associated with an increased risk of cervical cancer. Hepatitis B virus (HBV) and hepatitis C virus (HCV) infections can lead to liver inflammation, cirrhosis, and liver cancer (hepatocellular carcinoma), but they do not specifically increase the risk of cervical cancer.

B. Human papillomavirus (HPV):

- Human papillomavirus (HPV) infection is strongly associated with an increased risk of cervical cancer. HPV is a sexually transmitted virus that can infect the cells of the cervix, leading to cellular changes that may progress to cervical dysplasia and cervical cancer over time. Persistent infection with high-risk strains of HPV, particularly HPV types 16 and 18, is a major risk factor for the development of cervical cancer.

C. Cytomegalovirus (CMV):

- Cytomegalovirus (CMV) is a common virus in the herpesvirus family. While CMV infection can cause complications in certain populations, such as congenital CMV infection in infants born to mothers with primary CMV infection during pregnancy, it is not known to be directly associated with an increased risk of cervical cancer.

D. Epstein-Barr virus (EBV):

- Epstein-Barr virus (EBV) is a herpesvirus that is best known for causing infectious mononucleosis (mono). EBV infection has been associated with certain types of cancers, such as Burkitt's lymphoma, Hodgkin's lymphoma, and nasopharyngeal carcinoma. However, EBV infection is not directly linked to an increased risk of cervical cancer.

A. Stability of the woman's emotional and psychological status:

Emotional and psychological well-being are undoubtedly important factors in pregnancy outcomes. However, in the context of gestational diabetes, while stress and psychological factors can influence overall health, including blood sugar levels, they are not the primary focus when discussing reducing complications associated with diabetes during pregnancy. While managing stress and promoting emotional stability are important aspects of prenatal care, they are not directly related to reducing complications specifically associated with gestational diabetes.

B. Reduction in retinopathy risk by frequent ophthalmologic evaluations:

Diabetic retinopathy is a complication of diabetes that affects the eyes and can lead to vision impairment or blindness if left untreated. While regular ophthalmologic evaluations are crucial for individuals with diabetes to monitor for retinopathy and other eye complications, this factor is not the most important in reducing complications associated with pregnancy and diabetes. Gestational diabetes primarily affects pregnancy outcomes, and while retinopathy risk is a concern in the long term for individuals with diabetes, it is not the primary focus during pregnancy.

C. Control of blood urea nitrogen (BUN) levels for optimal kidney function:

Blood urea nitrogen (BUN) levels are markers of kidney function, and kidney complications can be a concern in individuals with diabetes, including gestational diabetes. However, during pregnancy, the focus is primarily on controlling blood glucose levels to reduce complications associated with gestational diabetes. While kidney function is important and should be monitored in pregnant women with gestational diabetes, it is not the most crucial factor in reducing complications specifically related to pregnancy and diabetes.

D. Degree of blood glucose control achieved during the pregnancy:

This is the most important factor in reducing complications associated with pregnancy and gestational diabetes. Controlling blood glucose levels is paramount in managing gestational diabetes to reduce the risk of complications for both the mother and the baby. Tight glycemic control helps to minimize the risk of adverse outcomes such as macrosomia, birth trauma, preterm birth, and other complications associated with uncontrolled blood sugar levels during pregnancy.
