Which viral sexually transmitted infection is characterized by a primary infection followed by recurrent episodes?

Herpes simplex virus (HSV)-2

Human papillomavirus (HPV)

Cytomegalovirus (CMV)

Human immunodeficiency virus (HIV)

Answer and Explanation

The Correct Answer is A

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.

Correct Answer is D

Explanation

Choice A reason: This is incorrect because oral antiviral therapy is not effective for PID, which is caused by bacterial infection. Antiviral therapy is used for viral infections, such as herpes or HIV.

Choice B reason: This is incorrect because antibiotics only until symptoms subside is not sufficient for PID, which can cause serious complications, such as infertility, ectopic pregnancy, or chronic pelvic pain. Antibiotics should be continued for the full course of treatment, usually 14 days, to ensure complete eradication of the infection.

Choice C reason: This is incorrect because frequent pelvic examination to monitor the progress of healing is not recommended for PID, which can cause inflammation and irritation of the pelvic organs. Pelvic examination should be avoided or minimized to prevent further trauma or spread of the infection.

Choice D reason: This is correct because bed rest in a semi-Fowler position is beneficial for PID, which can cause fluid accumulation and pressure in the pelvic cavity. Bed rest helps to reduce inflammation and pain, while semi-Fowler position helps to drain the fluid and prevent abscess formation.

A. compensate for decreased renal plasma flow. B. prevent maternal and fetal dehydration. C. provide adequate perfusion of the placenta. D. eliminate metabolic wastes of the mother.

Correct Answer is C

Explanation

Choice A reason: Vascular volume increases during pregnancy to meet the increased oxygen and nutrient demands of the fetus, not to compensate for decreased renal plasma flow. In fact, renal plasma flow increases by 50% to 80% during pregnancy to facilitate the excretion of metabolic wastes.

Choice B reason: Vascular volume increases during pregnancy to ensure adequate blood supply to the uterus and other organs, not to prevent maternal and fetal dehydration. Dehydration can occur due to vomiting, diarrhea, or inadequate fluid intake, and it can be prevented by drinking enough fluids and replacing electrolytes.

Choice C reason: Vascular volume increases during pregnancy to provide adequate perfusion of the placenta, which is the main organ of gas exchange and nutrient delivery for the fetus. The placenta receives about 10% of the maternal cardiac output at term.

Choice D reason: Vascular volume increases during pregnancy to support the growth and development of the fetus and the maternal tissues, not to eliminate metabolic wastes of the mother. Metabolic wastes are eliminated by the kidneys, lungs, skin, and gastrointestinal tract.
