The nurse is preparing to administer the contraceptive form of medroxyprogesterone. What route is appropriate?

Choice A reason: A 32-year-old client who has benign breast disease does not have a contraindication for receiving oral contraceptives. Benign breast disease is not associated with an increased risk of breast cancer or thromboembolic events. However, the nurse should advise the client to perform regular breast self-examinations and report any changes.

Choice B reason: A 26-year-old client who has migraine headaches at the start of each menstrual cycle does not have a contraindication for receiving oral contraceptives. Migraine headaches that are related to the menstrual cycle may actually improve with oral contraceptives, as they can regulate the hormonal fluctuations. However, the nurse should monitor the client for any signs of stroke or hypertension, as these are rare but serious complications of oral contraceptives.

Choice C reason: A 28-year-old client who has a history of pelvic inflammatory disease does not have a contraindication for receiving oral contraceptives. Pelvic inflammatory disease is an infection of the reproductive organs that can cause infertility, chronic pain, and ectopic pregnancy. Oral contraceptives can reduce the risk of pelvic inflammatory disease by creating a thick cervical mucus that prevents the entry of bacteria. However, the nurse should remind the client that oral contraceptives do not protect against sexually transmitted infections, and that barrier methods should be used in addition.

Choice D reason: A 38-year-old client who reports smoking one pack of cigarettes every day has a contraindication for receiving oral contraceptives. Smoking increases the risk of cardiovascular diseases, such as myocardial infarction, stroke, and peripheral vascular disease. Oral contraceptives also increase the risk of these diseases, especially in women older than 35 years. Therefore, the combination of smoking and oral contraceptives can have a synergistic effect and cause serious harm. The nurse should recommend other methods of contraception for this client, such as intrauterine devices, implants, or injections.

Choice A reason: Vaginal cultures are not necessary for oral contraceptive therapy. They are used to diagnose infections such as bacterial vaginosis, yeast infection, or sexually transmitted diseases.

Choice B reason: Complete blood count is not essential for oral contraceptive therapy. It is used to measure the number and types of blood cells, such as red blood cells, white blood cells, and platelets.

Choice C reason: Serum potassium level is the most important laboratory test for oral contraceptive therapy. This is because some oral contraceptives can increase the risk of hyperkalemia, which is a high level of potassium in the blood. Hyperkalemia can cause serious complications such as cardiac arrhythmias, muscle weakness, and paralysis.

Choice D reason: Pregnancy test is not a laboratory test, but a urine test. It is important to rule out pregnancy before starting oral contraceptive therapy, but it is not the most important test for the nurse to assess.
