A 32-year-old primigravida is admitted with a diagnosis of ectopic pregnancy. Nursing care is based on the knowledge that:

Choice A reason: HSV-2 is a viral infection that causes genital herpes. It is transmitted through sexual contact and can cause painful blisters and ulcers in the genital area. The primary infection is usually the most severe and lasts for several weeks. After the primary infection, the virus remains dormant in the nerve cells and can reactivate periodically, causing recurrent episodes of genital herpes. The frequency and severity of the recurrences vary from person to person.

Choice B reason: HPV is a viral infection that causes genital warts and cervical cancer. It is transmitted through sexual contact and can infect the skin and mucous membranes of the genital area. The primary infection is often asymptomatic and may clear spontaneously or persist for years. HPV does not cause recurrent episodes of genital warts or cervical cancer, but it can increase the risk of developing these conditions over time.

Choice C reason: CMV is a viral infection that causes flu-like symptoms and can affect various organs. It is transmitted through bodily fluids such as saliva, urine, blood, and semen. The primary infection is usually mild and may go unnoticed. After the primary infection, the virus remains latent in the body and can reactivate in people with weakened immune systems, causing serious complications. CMV does not cause recurrent episodes of flu-like symptoms or organ damage, but it can worsen the condition of people with HIV or AIDS.

Choice D reason: HIV is a viral infection that causes acquired immunodeficiency syndrome (AIDS). It is transmitted through sexual contact, blood transfusion, or sharing of needles. The primary infection is often accompanied by flu-like symptoms and lasts for a few weeks. After the primary infection, the virus gradually destroys the immune system and makes the person vulnerable to opportunistic infections and cancers. HIV does not cause recurrent episodes of flu-like symptoms or AIDS, but it can progress to AIDS over time.

Choice A reason: Quickening is the first perception of fetal movement by the mother, usually occurring between 16 and 20 weeks of gestation. It is a presumptive sign of pregnancy, as it can be subjective and influenced by other factors such as gas or peristalsis.

Choice B reason: A positive pregnancy test is a probable sign of pregnancy, as it indicates the presence of human chorionic gonadotropin (hCG) in the urine or blood. However, it is not conclusive, as it can be affected by false positives or false negatives, or by other conditions that produce hCG.

Choice C reason: Braxton Hicks contractions are irregular, painless uterine contractions that occur throughout pregnancy. They are a probable sign of pregnancy, as they indicate uterine activity and preparation for labor. However, they are not diagnostic, as they can also occur in non-pregnant women or in response to other stimuli.

Choice D reason: Fetal movement palpated by the nurse-midwife is a positive sign of pregnancy, as it confirms the presence of a living fetus in the uterus. It is an objective and reliable sign that can be detected by a skilled examiner after 20 weeks of gestation.
