Rationale: Saheli' is not a steroidal preparation, it is a non-steroidal oral contraceptive.

Correct Answer: A

Rationale: The correct answer is A: Mons veneris. The mons veneris and labia majora are considered external genitalia as they are visible externally. The vagina and cervix, on the other hand, are internal structures. The vagina is the canal leading from the external genitals to the cervix, which is the lower, narrow portion of the uterus.

Correct Answer: A

Rationale: The correct answer is A: 'by providing adequate information and counseling.' Respecting clients' rights to informed consent involves ensuring that patients are adequately informed about the procedures they will undergo. This includes providing them with all necessary information and counseling to make an informed decision. Choice B is incorrect because forcing patients to sign consent forms does not ensure that they are fully informed or that their rights are respected. Choice C is incorrect as involving a senior medical superintendent to sign consent forms does not guarantee that patients are adequately informed. Choice D is incorrect because simply telling the patient to sign the consent form does not fulfill the requirement of providing adequate information for informed consent.

Correct Answer: A

Rationale: Metrorrhagia refers to irregular menstrual bleeding that occurs between periods. Cervical carcinoma, a type of cancer that develops in the cervix, can lead to metrorrhagia. Uterine polyps, which are growths attached to the inner wall of the uterus, can also cause abnormal bleeding. While infections like Chlamydia can cause abnormal vaginal bleeding, they are not common causes of metrorrhagia. Cervical endometriosis, although a possible gynecological condition, is not a typical cause of metrorrhagia. Therefore, the correct answer is cervical carcinoma as it is a known cause of metrorrhagia, making the other options incorrect.

Correct Answer: A

Rationale: Contraceptive oral pills primarily work by preventing ovulation, which means Choice A is correct. Choices B and C are incorrect because oral contraceptive pills do not kill ova or sperms. Choice D is incorrect because only preventing ovulation is the primary mechanism of action for oral contraceptive pills.
