A nurse is teaching a group of students about the ovarian cycle. Complete the following sentence using the list of options. The follicular phase is when the follicle is maturing under the influence of the _______.
Adrenocorticotropic hormone.
Follicle-stimulating hormone.
Oxytocin.
Luteinizing hormone.
Prolactin.
The Correct Answer is B
Choice A rationale
Adrenocorticotropic hormone (ACTH) is produced by the pituitary gland and stimulates the adrenal glands to release cortisol. It is not involved in the maturation of ovarian follicles.
Choice B rationale
Follicle-stimulating hormone (FSH) is produced by the pituitary gland and stimulates the growth and maturation of ovarian follicles. It is the correct hormone involved in the follicular phase of the ovarian cycle.
Choice C rationale
Oxytocin is a hormone involved in childbirth and lactation. It stimulates uterine contractions and milk ejection but is not involved in the maturation of ovarian follicles.
Choice D rationale
Luteinizing hormone (LH) is produced by the pituitary gland and triggers ovulation and the formation of the corpus luteum. It is not involved in the maturation of ovarian follicles during the follicular phase.
Choice E rationale
Prolactin is a hormone that stimulates milk production in the mammary glands. It is not involved in the maturation of ovarian follicles.
Choice F rationale
Progesterone is a hormone produced by the corpus luteum and the placenta during pregnancy. It prepares the endometrium for implantation and maintains pregnancy but is not involved in the maturation of ovarian follicles.

Correct Answer is ["C","E","G"]
Explanation
Choice C rationale
Lower abdominal cramping during early pregnancy can be a sign of various conditions, including normal uterine growth, but it can also indicate potential complications such as an ectopic pregnancy or miscarriage. It is crucial to report this symptom to the provider to rule out any serious issues and ensure the safety of both the mother and the fetus.
Choice E rationale
Vaginal spotting during early pregnancy can be a sign of implantation bleeding, which is usually harmless. However, it can also indicate more serious conditions such as a threatened miscarriage or an ectopic pregnancy. Reporting this symptom to the provider is essential for further evaluation and appropriate management.
Choice G rationale
Dysuria, or painful urination, can be a sign of a urinary tract infection (UTI), which is common during pregnancy due to hormonal changes and the growing uterus pressing on the bladder. UTIs can lead to complications if left untreated, so it is important to report this symptom to the provider for prompt diagnosis and treatment.
Correct Answer is B
Explanation
Choice A rationale
Fetal movements, known as quickening, are typically felt by the mother between 16 and 25 weeks of pregnancy, not specifically at week 245.
Choice B rationale
The baby’s heartbeat can be detected by 10-12 weeks of pregnancy using a Doppler ultrasound device. This is an important milestone in fetal development and prenatal care.
Choice C rationale
Lanugo, the fine hair covering the fetus, usually appears around 20 weeks of pregnancy and starts to disappear closer to the end of the third trimester, not specifically by week 355.
Choice D rationale
The sex of the baby is determined at conception, but it can be detected via ultrasound around 18-20 weeks of pregnancy, not by week 85.
