A client 12 weeks pregnant comes to the emergency department with abdominal cramping and moderate vaginal bleeding. Speculum examination reveals 2 to 3 cm cervical dilation. The nurse would document these findings as which of the following?
- A. Threatened abortion
- B. Inevitable abortion
- C. Complete abortion
- D. Missed abortion
Correct Answer: B
Rationale: The nurse would document these findings as an inevitable abortion. Inevitable abortion is characterized by cervical dilation with or without rupture of membranes and is associated with moderate to heavy vaginal bleeding. 'Threatened abortion' (choice A) refers to vaginal bleeding with a closed cervical os and no tissue passage. 'Complete abortion' (choice C) involves the passage of all products of conception. 'Missed abortion' (choice D) is the retention of a failed intrauterine pregnancy for an extended period without symptoms.
What is the role of the prolactin hormone?
- A. Stimulates the development of milk-producing tissue.
- B. Stimulates milk storage.
- C. Stimulates milk production.
- D. Stimulates milk ejection.
Correct Answer: C
Rationale: The correct answer is C: 'Stimulates milk production.' Prolactin hormone is responsible for promoting the production of milk in the mammary glands. This hormone does not directly stimulate the development of milk-producing tissue (Choice A), milk storage (Choice B), or milk ejection (Choice D). While these functions are related to lactation, the primary role of prolactin is to facilitate milk production.

- A. Placenta
- B. Chorion
- C. Endometrium
- D. None of the above
Correct Answer: A
Rationale: The correct answer is A: Placenta. The placenta is a temporary organ that connects a mammalian mother to its foetus.

Choice B, Chorion, is incorrect as it is a part of the fetal membrane but not the organ that connects the mother to the fetus. Choice C, Endometrium, is incorrect as it is the lining of the uterus where implantation occurs but is not the organ responsible for connecting the mother to the fetus. Choice D, None of the above, is incorrect as the placenta specifically fits the description provided in the question.
