Matching the method to the client
Contraceptive counselling starts with the client's goals: desired effectiveness, plans for future pregnancy, tolerance of hormones, ability to adhere to a daily routine, breastfeeding status, cost and protection from infection. Nursing responsibility is to give accurate, non-judgemental information and support the client's informed choice, not to recommend a personal preference — and answers that impose the nurse's values are always wrong.
Effectiveness is described in typical use as well as perfect use. Long-acting reversible methods — intrauterine devices and the subdermal implant — are the most effective because they remove user error. Injectables, pills, patches and rings depend on adherence, and barrier methods and fertility awareness methods have the widest gap between perfect and typical use.
Sterilisation is permanent and requires informed consent with counselling that reversal is not guaranteed. Emergency contraception is more effective the sooner it is taken, generally within seventy-two to one hundred and twenty hours depending on the method, and works primarily by delaying ovulation. A copper IUD is the most effective emergency option and provides ongoing contraception.
| Method | How it works | Key teaching point |
|---|---|---|
| Combined pill, patch, ring | Suppresses ovulation | Same time daily; ACHES warning signs; smoking risk over 35 |
| Progestin-only pill | Thickens cervical mucus | Strict timing — within a 3-hour window each day |
| Depot injection | Suppresses ovulation for 3 months | Bone density loss; calcium, vitamin D, weight-bearing exercise |
| Implant | Progestin for up to 3–5 years | Irregular bleeding is common and not harmful |
| Hormonal or copper IUD | Local effect, up to 3–10 years | Check strings monthly; report fever or foul discharge |
| Condom | Barrier | Only method reducing STI transmission |
Hormonal methods: teaching and cautions
Combined hormonal methods contain oestrogen and progestin. Absolute contraindications tested repeatedly include a history of deep vein thrombosis or pulmonary embolism, known thrombogenic mutations, stroke or ischaemic heart disease, migraine with aura, uncontrolled hypertension, active liver disease, oestrogen-dependent cancer, smoking in a client over thirty-five, and pregnancy. Recognising one of these in a stem means the method is unsafe regardless of the client's preference.
Missed-dose rules appear often. For combined pills, one missed dose is taken as soon as remembered, even if that means two in a day, and no backup is required. Two or more missed doses require taking the most recent missed pill, continuing the pack, and using backup contraception for seven days, with consideration of emergency contraception if intercourse occurred. Progestin-only pills are stricter: if the dose is more than three hours late, take it and use backup for forty-eight hours.
Side effects to normalise include breakthrough bleeding in the first months, breast tenderness and nausea; encourage taking pills with food or at bedtime. Interactions matter: certain anticonvulsants, rifampin and St John's wort reduce effectiveness. Depot medroxyprogesterone is given every eleven to thirteen weeks and causes amenorrhoea, weight gain and reversible bone mineral density loss, so calcium, vitamin D and weight-bearing exercise are taught and return to fertility may be delayed up to a year.
IUDs, implants and barrier methods
Intrauterine devices are inserted by a provider and are effective for three to ten years depending on type. Hormonal devices often reduce bleeding and cramping, while the copper device may increase both, especially in the first months. Clients check for the strings monthly after menses and report strings that feel longer, shorter or absent, which may indicate expulsion or migration. Warning signs are remembered as period late, abnormal spotting or bleeding, abdominal pain or pain with intercourse, infection with abnormal discharge, and not feeling well with fever or chills. Pregnancy with an IUD in place raises ectopic risk and requires prompt evaluation.
The subdermal implant is placed in the upper inner arm and lasts three to five years, with irregular bleeding as the most common reason for discontinuation. Teaching normalises this pattern and confirms the client can palpate the implant.
Barrier methods include male and female condoms, diaphragms and cervical caps with spermicide. Diaphragms are fitted by a provider, refitted after significant weight change or childbirth, inserted before intercourse, left in place at least six hours afterwards but no more than twenty-four because of toxic shock risk, and washed and inspected for holes. Only condoms protect against sexually transmitted infections, so dual method use is taught when infection risk exists. Oil-based lubricants damage latex.
- •IUD: check strings monthly; report absence, fever, foul discharge or severe pain
- •Implant: irregular bleeding is expected and not dangerous
- •Diaphragm: keep in place 6 hours, remove within 24
- •Only condoms reduce STI transmission — teach dual protection
- •Water-based lubricants only with latex
Fertility awareness, postpartum and lactation
Fertility awareness methods rely on identifying the fertile window through basal body temperature, which rises about half a degree Celsius after ovulation, cervical mucus that becomes clear, stretchy and slippery near ovulation, and calendar tracking. These methods require regular cycles, consistent daily observation and partner cooperation, and have high typical-use failure rates. Teaching includes abstaining or using a barrier through the fertile window.
After birth, method choice depends on breastfeeding and thrombosis risk. Combined hormonal contraceptives are generally avoided in the first weeks postpartum because of clot risk, and progestin-only methods are preferred while breastfeeding. Lactational amenorrhoea provides some protection only when the infant is under six months, exclusively breastfed including at night, and menses have not returned — all three conditions are required, and clients are counselled that ovulation can precede the first period.
Perimenopausal clients still require contraception until twelve consecutive months without menses. Counselling in this group also covers cardiovascular risk, cycle irregularity and the fact that hormonal contraception may mask menopausal transition.
Exam strategy for contraception items
Most items are teaching or evaluation questions phrased as which statement indicates understanding or requires further teaching. Read for the specific number — three-hour window, seven days of backup, six to twenty-four hours for a diaphragm, twelve weeks for injections — because the distractors usually differ only in the number.
Safety items hinge on contraindications and warning signs. If the stem includes a smoker over thirty-five, a clot history, migraine with aura or uncontrolled hypertension and offers a combined method, that method is the wrong choice. If it describes chest pain, sudden severe headache, visual change or unilateral leg pain in a pill user, treat it as a possible thrombotic event and act immediately.
Finally, watch for values-based distractors. Answers that judge the client's choices, involve a partner without consent or steer toward a specific method are wrong; the correct option gives accurate information and supports informed decision-making.
