After teaching a group of adolescent girls about female reproductive development, the nurse determines that teaching was successful when the girls state that menarche is defined as a woman's first:

Choice A: Diarrhea is not the correct answer because it is not a common adverse effect of radiation treatment for breast cancer. Diarrhea is a condition that causes loose, watery, or frequent stools. It can be caused by various factors such as infection, medication, or food intolerance. It is more likely to occur as an adverse effect of radiation treatment for cancers that affect the digestive system, such as colorectal or stomach cancer.

Choice B: Anorexia is not the correct answer because it is not a common adverse effect of radiation treatment for breast cancer. Anorexia is a condition that causes loss of appetite or interest in food. It can be caused by various factors such as depression, stress, or nausea. It is more likely to occur as an adverse effect of chemotherapy or other systemic treatments for cancer that affect the whole body.

Choice C: Fatigue is the correct answer because it is a common adverse effect of radiation treatment for breast cancer. Fatigue is a condition that causes extreme tiredness or exhaustion that is not relieved by rest or sleep. It can be caused by various factors such as anemia, inflammation, or pain. It is a common adverse effect of radiation treatment for any type of cancer, as radiation can damage healthy cells and tissues and affect the body's energy production.

Choice D: Alopecia is not the correct answer because it is not a common adverse effect of radiation treatment for breast cancer. Alopecia is a condition that causes hair loss or thinning on the scalp or other parts of the body. It can be caused by various factors such as genetics, hormones, or infection. It is more likely to occur as an adverse effect of chemotherapy or other systemic treatments for cancer that affect the whole body.

Choice A: Vaginal pH of 3 is not the correct answer because it is not a finding of bacterial vaginosis. Vaginal pH is a measure of how acidic or alkaline the vaginal environment is. A normal vaginal pH ranges from 3.8 to 4.5, which helps prevent infections by maintaining a balance of healthy bacteria (lactobacilli). Bacterial vaginosis can cause an increase in vaginal pH above 4.5, which allows harmful bacteria (anaerobes) to grow and cause symptoms.

Choice B: Cervical bleeding on contact is not the correct answer because it is not a finding of bacterial vaginosis. Cervical bleeding on contact is a sign of inflammation or injury to the cervix, which is the lower part of the uterus that connects to the vagina. It can be caused by various factors such as infection, trauma, or cancer. Bacterial vaginosis does not affect the cervix directly, but it can increase the risk of other infections or complications that may cause cervical bleeding.

Choice C: Fishy odor of discharge is the correct answer because it is a finding of bacterial vaginosis. The fishy odor of discharge is a characteristic symptom of bacterial vaginosis that occurs due to the breakdown of organic compounds (amines) by the anaerobic bacteria. The odor is usually more noticeable after sexual intercourse or during menstruation.

Choice D: Yellowish-green discharge is not the correct answer because it is not a finding of bacterial vaginosis. Yellowish-green discharge is a sign of infection or inflammation of the vagina or cervix, such as trichomoniasis, gonorrhea, or chlamydia. These infections can cause symptoms such as itching, burning, or pain in the genital area. Bacterial vaginosis usually causes a thin, gray-white, or milky discharge that does not cause irritation or discomfort.
