Oxytocin is the hormone responsible for stimulating contractions during labor. Therefore, the presence of Braxton Hicks contractions indicates the preparation of the uterus for labor under the influence of oxytocin. Choices A, C, and D are incorrect as they do not directly relate to the physiological mechanism of Braxton Hicks contractions.

Soft spots that refers to unossified areas in an infants skull is termed as
- A. Sulcus
- B. Sinus
- C. Fontanelle
- D. Suture
Correct Answer: C
Rationale: The correct answer is C: Fontanelle. Fontanelles are soft spots in an infant's skull where the bones have not yet fully fused. They allow for the baby's brain to grow and accommodate the rapid brain development during the early months of life. Sulcus refers to a groove or furrow, sinus is a cavity within a bone, and suture is the line where two bones meet. These terms do not specifically refer to the unossified areas in an infant's skull, making them incorrect choices.
During the week following ovulation, the endometrium increases in thickness to 5 to 6 millimeters. What stimulates this increase in thickness?
- A. Luteinizing hormone
- B. Estrogen from the corpus luteum
- C. Progesterone from the corpus luteum
- D. Follicle-stimulating hormone
Correct Answer: C
Rationale: The correct answer is C: Progesterone from the corpus luteum. After ovulation, the corpus luteum forms from the ruptured follicle and secretes progesterone. Progesterone is responsible for preparing the endometrium for potential implantation of a fertilized egg by increasing its thickness. Luteinizing hormone (A) triggers ovulation but does not directly affect endometrial thickness. Estrogen from the corpus luteum (B) also plays a role in preparing the endometrium but does not specifically stimulate the increase in thickness. Follicle-stimulating hormone (D) primarily regulates the development of ovarian follicles and does not directly influence endometrial thickness.

What is produced by the ovaries?
- A. Primary oocytes, insulin and estrogen
- B. Secondary oocytes, progesterone and cortisol
- C. Tertiary oocytes, insulin and estrogen
- D. Secondary oocytes, estrogen and progesterone
Correct Answer: D
Rationale: The correct answer is D because the ovaries produce secondary oocytes, which are released during ovulation for fertilization. Additionally, the ovaries produce estrogen and progesterone, which are essential for the menstrual cycle and reproductive health. Choice A is incorrect as primary oocytes are present before birth and insulin is produced by the pancreas. Choice B is incorrect because cortisol is produced by the adrenal glands, not the ovaries. Choice C is incorrect as tertiary oocytes do not exist, and insulin is produced by the pancreas.
The following structures are felt during bimanual pelvic examination
- A. Ovary
- B. Uterus
- C. Fallopian Tube
- D. Cervix
Correct Answer: B
Rationale: The correct answer is B: Uterus. During a bimanual pelvic examination, the examiner can palpate the uterus between their fingers. The uterus is a key structure that can be felt for its size, shape, and position. The ovaries, fallopian tubes, and cervix are not typically felt during a bimanual exam as they are located deeper within the pelvis and are not easily palpable. Palpating the ovaries directly is not typically part of a routine pelvic examination due to their small size and position behind the uterus. The fallopian tubes are also not typically palpable during a bimanual exam as they are located laterally to the uterus. The cervix may be felt during the exam, but it is not the main structure that is typically palpated during a bimanual pelvic examination.
