Medicinal calcium salts are indicated for:

Correct Answer: A

Rationale: The correct answer is A: Prevention of osteoporosis. Medicinal calcium salts are commonly prescribed to prevent osteoporosis due to their role in maintaining bone density. Calcium is essential for bone health and helps prevent bone loss associated with osteoporosis. Choice B: Hastening fracture union is incorrect because while calcium is important for bone healing, it is not typically used as the primary treatment to hasten fracture union. Choice C: Peripheral neuritis is incorrect because calcium salts are not indicated for the treatment of peripheral neuritis. Peripheral neuritis is often treated with medications such as B vitamins. Therefore, the correct choice is A as medicinal calcium salts are specifically indicated for the prevention of osteoporosis.

Correct Answer: C

Rationale: The correct answer is C: Endometrial carcinoma. Oral contraceptives actually decrease the risk of developing endometrial cancer by regulating hormone levels. A: Hypertension can be a side effect of oral contraceptives due to changes in blood pressure. B: Leg vein thrombosis risk increases due to estrogen in oral contraceptives causing blood clotting. D: Gall stones risk can increase with oral contraceptives due to changes in bile composition.

Correct Answer: B

Rationale: Rationale: Levonorgestrel is the recommended emergency contraceptive. Choice A includes ethinylestradiol, which is not needed. Choice C uses Mifepristone, which is not typically used for emergency contraception. Choice D is incorrect because it includes options A and C, which are not recommended. Choice B, Levonorgestrel 0.75 mg taken twice 12 hours apart, is the correct regimen as per guidelines. It provides effective protection against unintended pregnancy without the need for additional unnecessary components.

Correct Answer: A

Rationale: The correct answer is A: Combined estrogen + progestin oral pill. This form of hormonal contraception is the most popular because it is highly effective in preventing pregnancy by inhibiting ovulation, thickening cervical mucus, and altering the endometrium. It is easy to use, reversible, and offers additional non-contraceptive benefits like reducing menstrual cramps and acne. Phased estrogen + progestin oral pill (B) and postcoital estrogen + progestin pill (C) are not commonly used methods. Depot progestin injection (D) is effective but less popular due to the need for healthcare provider administration and potential side effects like irregular bleeding.

Correct Answer: C

Rationale: The correct answer is C: First term abortion. Mifepristone is primarily indicated for medical abortion in the first trimester of pregnancy. It works by blocking the hormone progesterone, leading to the detachment of the embryo from the uterine wall. Endometriosis (A) is not a primary indication for mifepristone. Cushing's syndrome (B) is typically treated with medications that lower cortisol levels, not mifepristone. Second term abortion (D) is usually performed through other methods like dilation and curettage, not with mifepristone.
