A client is to receive enoxaparin 30 mg subcutaneously. Available is enoxaparin 40 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Choice A: A 26-year-old client who has migraine headaches at the start of each menstrual cycle is not the correct answer because they do not have a contraindication for receiving oral contraceptives. Oral contraceptives are pills that contain synthetic hormones (estrogen and progestin) that prevent ovulation and pregnancy. They can also help reduce menstrual cramps, bleeding, and migraines in some women. However, oral contraceptives may increase the risk of stroke in women who have migraines with aura (visual disturbances), so they should be used with caution and under medical supervision.

Choice B: A 28-year-old client who has a history of pelvic inflammatory disease is not the correct answer because they do not have a contraindication for receiving oral contraceptives. Pelvic inflammatory disease is an infection that affects the female reproductive organs, such as the uterus, fallopian tubes, or ovaries. It can be caused by various bacteria, such as chlamydia or gonorrhea, and can lead to infertility, ectopic pregnancy, or chronic pelvic pain if left untreated. Oral contraceptives can help prevent pelvic inflammatory disease by creating a thick cervical mucus that blocks the entry of bacteria into the uterus.

Choice C: A 32-year-old client who has benign breast disease is not the correct answer because they do not have a contraindication for receiving oral contraceptives. Benign breast disease is a term that refers to various noncancerous conditions that affect the breast tissue, such as fibrocystic changes, fibroadenomas, or mastitis. They can cause symptoms such as breast pain, tenderness, or lumps. Oral contraceptives can help reduce the symptoms of benign breast disease by regulating the hormonal fluctuations that influence breast tissue growth.

Choice D: A 38-year-old client who reports smoking one pack of cigarettes every day is the correct answer because they have a contraindication for receiving oral contraceptives. Smoking is a habit that involves inhaling tobacco smoke, which contains harmful substances such as nicotine, tar, or carbon monoxide. Smoking can increase the risk of various diseases such as lung cancer, chronic obstructive pulmonary disease (COPD), or cardiovascular disease. Oral contraceptives can further increase the risk of cardiovascular disease in smokers, especially those who are over 35 years old, by increasing blood pressure, cholesterol levels, and clotting factors. Therefore, oral contraceptives are not recommended for smokers and alternative methods of contraception should be used instead.

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.
