Which hormone regulates the production of milk after childbirth?

Correct Answer: A

Rationale: The correct answer is Prolactin. Prolactin is the hormone responsible for regulating the production of milk after childbirth. It stimulates the mammary glands in the breasts to produce milk. Oxytocin, on the other hand, is responsible for the ejection of milk from the breasts. Estrogen and progesterone play roles in the menstrual cycle and pregnancy but are not directly involved in milk production. Therefore, choices B, C, and D are incorrect.

Correct Answer: B

Rationale: The endometrial tissue of the cervix is arranged in folds known as rugae, not Arbor vitae. Rugae are commonly found in anatomical structures like the stomach and bladder to allow expansion. Choices A, C, and D are incorrect. Racemose glands refer to branched compound glands, Arbor vitae is the tree-like appearance of the cerebellum, and Peritoneum is the serous membrane lining the abdominal cavity.

Correct Answer: B

Rationale: Vaginitis is characterized by symptoms such as vaginal itching, irritation, pain during coitus, and painful urination. However, heavy vaginal bleeding is not typically associated with vaginitis. Vaginal bleeding could be indicative of other conditions like cervical or endometrial issues, but it is not a common symptom of vaginitis.

Correct Answer: B

Rationale: The correct answer is B: Cord blood stem cells. The umbilical cord contains stem cells that are found in cord blood, known as cord blood stem cells. These stem cells have the potential to develop into various types of cells and are used in medical treatments. Pluripotent stem cells are typically found in embryos and have the ability to develop into any type of cell in the body, not specifically in the umbilical cord. Choice C, blood stem cells, is a vague term that does not specifically refer to the stem cells found in the umbilical cord. Choice D is incorrect as the umbilical cord does contain cord blood stem cells.

Correct Answer: A

Rationale: The correct answer is within a 20 Km radius. Primary Health Care services should be accessible within a 20 Km radius to ensure adequate coverage for all patients. This distance allows for a reasonable reach while ensuring that individuals can access essential healthcare services in a timely manner. Choices B, C, and D are incorrect as they offer distances that may limit accessibility and coverage, potentially leaving some patients without timely access to necessary healthcare.

Correct Answer: A

Rationale: Incomplete abortion is defined as part of the products of conception, especially the fetus, being expelled while the placenta and membranes are retained. This is the correct definition, making option A the right choice. Option B is incorrect as it describes a complete abortion. Option C is incorrect because in incomplete abortion, the products of conception are not retained in the uterus, and the cervix may be open. Option D is incorrect as it describes a situation more likely to be seen in an inevitable abortion.

Correct Answer: C

Rationale: Dysmenorrhoea is the medical term for painful menstruation. It is characterized by cramp-like abdominal pain that occurs just before or during menstruation. Choice A, heavy menstruation, is referred to as menorrhagia. Choice B, light menstruation, is not a term used to describe a specific menstrual condition. Choice D, infrequent menstruation, is known as oligomenorrhea, not dysmenorrhoea.

Correct Answer: A

Rationale: The correct answer is A: Ischiopubic arch. The outlet of the true pelvis is indeed anteriorly bounded by the ischiopubic arch, which consists of the ischium and the pubic bones. This structure forms the lower boundary of the pelvic outlet. The other choices, B, C, and D, are incorrect. The linea terminalis (pelvic brim) forms the upper boundary of the true pelvis, the coccyx is part of the bony pelvis but does not bound the pelvic outlet anteriorly, and the promontory of the sacrum is located in the posterior part of the pelvis, not the anterior boundary of the pelvic outlet.

Correct Answer: A

Rationale: During an ectopic pregnancy, a rupture in the ampullary portion of the tube is frequent. This is due to the increased pressure within the fallopian tube as the embryo grows, leading to the rupture of the tube. Choices B, C, and D are incorrect as they do not accurately describe the common occurrence of rupture in this specific part of the tube during an ectopic pregnancy.
