Examples of sexual risk behaviors associated with exposure to a sexually transmitted infection (STI) include: (Select all that apply.)

Choice A reason: Syphilis is a bacterial STI caused by Treponema pallidum. It is characterized by three stages: primary, secondary, and tertiary. It can cause serious complications such as neurosyphilis, cardiovascular syphilis, and congenital syphilis. However, it is not the most common bacterial STI.

Choice B reason: Candidiasis is a fungal infection caused by Candida albicans. It is not a STI, but rather an opportunistic infection that can affect the vagina, mouth, skin, or other mucous membranes. It can cause symptoms such as itching, burning, discharge, and inflammation.

Choice C reason: Gonorrhea is a bacterial STI caused by Neisseria gonorrhoeae. It can infect the urethra, cervix, rectum, throat, or eyes. It can cause symptoms such as dysuria, discharge, pelvic pain, and bleeding. It can also lead to complications such as pelvic inflammatory disease, epididymitis, infertility, and disseminated gonococcal infection. However, it is not the most common bacterial STI.

Choice D reason: Chlamydia is a bacterial STI caused by Chlamydia trachomatis. It is the most common bacterial STI, affecting about 2.86 million people in the United States in 2018. It can infect the urethra, cervix, rectum, throat, or eyes. It can cause symptoms such as dysuria, discharge, pelvic pain, and bleeding. It can also lead to complications such as pelvic inflammatory disease, epididymitis, infertility, and ectopic pregnancy.

Choice A reason: An antiemetic such as pyridoxine may be used to control vomiting in women with hyperemesis gravidarum, but it is not the initial treatment. The first priority is to restore fluid and electrolyte balance and prevent dehydration and hypovolemia.

Choice B reason: IV therapy is the initial treatment for women with hyperemesis gravidarum. It helps to correct fluid and electrolyte imbalances, prevent dehydration and hypovolemia, and restore normal blood pressure and urine output. IV fluids may also contain glucose, vitamins, and electrolytes to replenish losses.

Choice C reason: Enteral nutrition may be used to meet nutritional needs in women with hyperemesis gravidarum, but it is not the initial treatment. Enteral nutrition involves feeding through a tube inserted into the stomach or intestine. It may be considered if oral intake is not tolerated or adequate after IV therapy.

Choice D reason: Corticosteroids are not used to treat hyperemesis gravidarum. They are used to reduce inflammation in conditions such as asthma, rheumatoid arthritis, and allergic reactions. They have no effect on nausea and vomiting in pregnancy.
