A nurse is assessing the effectiveness of a patient's contraceptive method.
The patient is using spermicide alone.
Which of the following statements is correct?
Spermicide alone is 90% effective at preventing pregnancy when used correctly and consistently.
Spermicide alone is 72% effective at preventing pregnancy when used correctly and consistently.
Spermicide alone is 100% effective at preventing pregnancy when used correctly and consistently.
Spermicide alone is 50% effective at preventing pregnancy when used correctly and consistently.
The Correct Answer is B
The correct answer is choice B. Spermicide alone is 72% effective at preventing pregnancy when used correctly and consistently.
This means that out of 100 people who use spermicide as their only birth control method, about 28 will become pregnant in a year.
Choice A is wrong because spermicide alone is not 90% effective at preventing pregnancy. It is much less effective than other methods of birth control.
Choice C is wrong because spermicide alone is not 100% effective at preventing pregnancy. No method of birth control is 100% effective, except for abstinence.
Choice D is wrong because spermicide alone is not 50% effective at preventing pregnancy. It is slightly more effective than that, but still not very reliable.
Spermicide works by damaging the sperm and blocking the entrance to the cervix.
It needs to be inserted into the vagina before sex and reapplied every time. It does not protect against sexually transmitted infections (STIs) and may increase the risk of some STIs by irritating the vaginal lining. Spermicide is more effective when combined with another method of birth control, such as condoms or diaphragms.

Correct Answer is C
Explanation
The correct answer is choice C.Cervical infections are a contraindication for the use of spermicide because they can cause irritation and inflammation of the cervix, which can increase the risk of HIV and other STDs.Spermicide can also worsen existing infections by altering the vaginal flora and pH.
Choice A is wrong because history of cervical cancer is not a contraindication for the use of spermicide.However, women with cervical cancer should consult their doctor before using any form of contraception.
Choice B is wrong because allergy to latex condoms is not a contraindication for the use of spermicide.Spermicide can be used with non-latex condoms or other barrier methods, such as cervical caps or diaphragms.
Choice D is wrong because endometriosis is not a contraindication for the use of spermicide.Spermicide does not affect the growth of endometrial tissue outside the uterus.
