A client requests a recommendation for a hormone-free, easy to use form of contraception.
Which should the nurse suggest?

Choice A rationale

The copper intrauterine device (IUD) is a highly effective, long-acting reversible contraceptive option that does not contain hormones. It works by releasing copper ions, which create an inflammatory reaction in the uterus, toxic to sperm and eggs, thus preventing fertilization and implantation. Its mechanism is entirely non-hormonal, meeting the client's request.

Choice B rationale

A cervical ring, often referring to a vaginal ring like the NuvaRing, releases hormones (estrogen and progestin) to prevent ovulation. This contradicts the client's request for a hormone-free method of contraception. Hormonal methods work by altering the menstrual cycle and preventing the release of an egg.

Choice C rationale

A cervical cap is a barrier method that requires the use of spermicide to be effective. While it is hormone-free, it is not considered "easy to use" as it requires precise placement over the cervix before each act of intercourse and removal afterward, often necessitating practice for proper insertion and fit.

Choice D rationale

A diaphragm is a barrier method that, similar to a cervical cap, requires the use of spermicide for efficacy. It must be inserted before intercourse and left in place for several hours afterward. This method, while hormone-free, is not considered "easy to use" due to the dexterity and understanding required for proper placement and removal.

Choice A rationale

A normal serum sodium level ranges from 135 to 145 mEq/L. A value of 120 mEq/L is significantly below the normal range, indicating hyponatremia, not an elevated level. Therefore, reporting it as elevated would be incorrect.

Choice B rationale

While laboratory errors can occur, a serum sodium level of 120 mEq/L in a client with chronic renal failure is a plausible finding due to impaired fluid and electrolyte balance, making a repeat analysis not the immediate primary interpretation without further clinical context.

Choice C rationale

While electrolyte abnormalities are common in chronic renal failure, a serum sodium of 120 mEq/L is a low sodium level (hyponatremia), not necessarily an "expected" abnormality in the sense of being benign or typical without specific context. It reflects a significant imbalance.

Choice D rationale

Chronic renal failure often leads to fluid retention due to impaired kidney excretion. This excessive water retention dilutes the body's sodium concentration, leading to a condition known as dilutional hyponatremia, where the total body sodium may be normal or even elevated, but its concentration is lowered by the excess fluid.
