A client with trichomoniasis is to receive metronidazole. What should the nurse instruct the client to avoid while taking this drug?

Choice A: Menstrual is not the correct answer because it is the phase when estrogen levels are lowest. The menstrual phase occurs when the endometrium (the lining of the uterus) is shed along with blood and mucus through the vagina.

Choice B: Ischemic is not the correct answer because it is the phase when estrogen levels are decreasing. The ischemic phase occurs when the blood supply to the endometrium is reduced due to vasoconstriction (narrowing of blood vessels). This phase prepares the endometrium for shedding if fertilization does not occur.

Choice C: Secretory is not the correct answer because it is the phase when progesterone levels are highest. The secretory phase occurs when the endometrium becomes thick and spongy due to increased secretion of mucus and glycogen (a form of sugar). This phase provides a suitable environment for implantation if fertilization occurs.

Choice D: Proliferative is the correct answer because it is the phase when estrogen levels are highest. The proliferative phase occurs when the endometrium regenerates and grows due to increased stimulation by estrogen. This phase prepares the endometrium for implantation if fertilization occurs.

Choice A: Rectal incontinence is not the correct answer because it is not a disorder related to pelvic organ prolapse. Rectal incontinence is a condition that causes loss of control over bowel movements, resulting in leakage of stool or gas. It can be caused by various factors, such as nerve damage, muscle weakness, or diarrhea.

Choice B: Rectocele is the correct answer because it is a disorder related to pelvic organ prolapse. Rectocele is a condition that occurs when the rectum bulges into the vagina due to weakening of the pelvic floor muscles and connective tissue. It can cause symptoms such as constipation, difficulty emptying the bowel, or a feeling of pressure or fullness in the vagina.

Choice C: Urinary incontinence is the correct answer because it is a disorder related to pelvic organ prolapse. Urinary incontinence is a condition that causes loss of control over urination, resulting in leakage of urine or urgency to urinate. It can be caused by various factors, such as stress, urge, overflow, or mixed types of incontinence.

Choice D: Cystocele is the correct answer because it is a disorder related to pelvic organ prolapse. Cystocele is a condition that occurs when the bladder bulges into the vagina due to weakening of the pelvic floor muscles and connective tissue. It can cause symptoms such as frequent urination, difficulty emptying the bladder, or a feeling of pressure or fullness in the vagina.

Choice E: Enterocele is the correct answer because it is a disorder related to pelvic organ prolapse. Enterocele is a condition that occurs when the small intestine bulges into the vagina due to weakening of the pelvic floor muscles and connective tissue. It can cause symptoms such as lower back pain, pelvic pressure, or difficulty having bowel movements.
