- A. The day menstrual bleeding begins
- B. The day ovulation is detected
- C. The day cervical mucus becomes thin
- D. The day progesterone reaches its peak
Explanation: The first day of menstrual bleeding is day one of the menstrual cycle. Ovulation and the progesterone peak occur later, during the middle…
Correct answer: The day menstrual bleeding begins- A. Before it leaves the ovary
- B. During follicle development
- C. Only after fertilization occurs
- D. At the start of menstruation
Explanation: The secondary oocyte remains arrested in meiosis II and completes it only when a sperm penetrates the oocyte.
Correct answer: Only after fertilization occurs- A. Formation of a haploid ovum
- B. Formation of a diploid zygote
- C. Release of a mature follicle
- D. Formation of the corpus luteum
Explanation: Fertilization combines the haploid male and female nuclei to form a diploid zygote.
Correct answer: Formation of a diploid zygote- A. Human chorionic gonadotropin
- B. Follicle-stimulating hormone
- C. Oxytocin
- D. Prolactin
Explanation: Human chorionic gonadotropin, produced by the developing chorionic tissue, maintains the corpus luteum early in pregnancy.
Correct answer: Human chorionic gonadotropin- A. It becomes thick and forms a firm plug
- B. It becomes thin, clear and more stretchable
- C. It becomes dry and blocks sperm movement
- D. It becomes heavily blood-stained and clotted
Explanation: Rising oestrogen makes cervical mucus thinner, clearer and more stretchable, allowing sperm to pass more easily.
Correct answer: It becomes thin, clear and more stretchable- A. It produces sperm for the developing fetus
- B. It exchanges oxygen, nutrients and wastes
- C. It stores mature ova for later fertilization
- D. It directly opens the cervix during labour
Explanation: The placenta provides exchange of oxygen, nutrients and waste products between maternal and fetal blood without normally mixing them…
Correct answer: It exchanges oxygen, nutrients and wastes- A. Mild nausea after waking
- B. Breast tenderness during the day
- C. Severe pain with dizziness and bleeding
- D. Increased urinary frequency at night
Explanation: Severe unilateral pain with dizziness and bleeding may indicate a ruptured ectopic pregnancy and internal haemorrhage.
Correct answer: Severe pain with dizziness and bleeding- A. It contains 46 chromosomes before fertilization
- B. It contains 23 chromosomes before fertilization
- C. It contains 23 pairs after meiosis is complete
- D. It contains no chromosomes until fertilization
Explanation: Sperm and ova are haploid gametes, each normally containing 23 chromosomes.
Correct answer: It contains 23 chromosomes before fertilization- A. Fundus
- B. Myometrium
- C. Cervix
- D. Uterine tube
Explanation: The cervix is the lower narrow part of the uterus and communicates with the vagina through the cervical canal.
Correct answer: Cervix- A. They support and nourish developing sperm cells
- B. They produce testosterone for male development
- C. They store mature sperm cells for ejaculation
- D. They secrete fructose-rich fluid into semen
Explanation: Sertoli cells support developing sperm cells and help regulate spermatogenesis.
Correct answer: They support and nourish developing sperm cells- A. Maintaining the testes slightly below body temperature
- B. Producing hormones that stimulate sperm release
- C. Providing alkaline fluid for sperm movement
- D. Moving sperm from the testes into the urethra
Explanation: The scrotum helps keep the testes cooler than the abdominal cavity, which supports normal spermatogenesis.
Correct answer: Maintaining the testes slightly below body temperature- A. A thin, slightly alkaline fluid
- B. A thick fluid rich in ovarian hormones
- C. A mucus layer that nourishes the ovum
- D. A concentrated fluid containing mature sperm
Explanation: The prostate contributes a thin, slightly alkaline secretion that supports sperm activity and helps neutralize acidity.
Correct answer: A thin, slightly alkaline fluid- A. Human chorionic gonadotropin
- B. Follicle-stimulating hormone
- C. Luteinizing hormone
- D. Human placental lactogen
Explanation: Human chorionic gonadotropin, or hCG, is produced by trophoblastic tissue soon after implantation and is detected in urine and blood…
Correct answer: Human chorionic gonadotropin- A. It reduces secretion of follicle-stimulating hormone
- B. It increases secretion of luteinizing hormone
- C. It stimulates testosterone release from Leydig cells
- D. It causes contraction of the seminiferous tubules
Explanation: Inhibin provides negative feedback mainly by reducing FSH secretion, helping regulate sperm production.
Correct answer: It reduces secretion of follicle-stimulating hormone- A. Avoid digital vaginal examination and notify the provider
- B. Perform a digital examination to assess cervical dilation
- C. Encourage walking to assess whether bleeding decreases
- D. Apply firm fundal pressure to reduce the bleeding
Explanation: Painless bright-red bleeding in late pregnancy may indicate placenta previa, so a digital vaginal examination can provoke severe…
Correct answer: Avoid digital vaginal examination and notify the provider- A. Massage the fundus and assess the response
- B. Place the woman flat and restrict oral fluids
- C. Apply an abdominal binder over the uterus
- D. Encourage the woman to walk to the bathroom
Explanation: A boggy uterus commonly indicates uterine atony, a major cause of postpartum haemorrhage.
Correct answer: Massage the fundus and assess the response- A. Avoid prolonged testicular heat because it can impair sperm production
- B. Use tight clothing to keep the testes close to the body
- C. Take extra testosterone to increase the number of sperm cells
- D. Reduce water intake to prevent dilution of seminal fluid
Explanation: Excessive heat can interfere with spermatogenesis because sperm production requires a temperature slightly below core body temperature.
Correct answer: Avoid prolonged testicular heat because it can impair sperm production- A. It allows exchange of oxygen and nutrients across a barrier
- B. It normally allows maternal and fetal blood to mix freely
- C. It produces all fetal blood cells throughout pregnancy
- D. It carries urine from the fetal bladder to the mother's kidneys
Explanation: The placenta permits exchange of oxygen, nutrients, and wastes between maternal and fetal circulations across placental tissue.
Correct answer: It allows exchange of oxygen and nutrients across a barrier- A. The findings are consistent with menopause
- B. The findings indicate the middle of the fertile cycle
- C. The findings indicate excessive corpus luteum activity
- D. The findings indicate a normal early pregnancy
Explanation: Menopause is associated with ovarian failure, reduced oestrogen production, and loss of negative feedback, which causes FSH to rise.
Correct answer: The findings are consistent with menopause- A. Vas deferens
- B. Seminiferous tubule
- C. Seminal vesicle
- D. Bulbourethral gland
Explanation: The vas deferens is a muscular duct that carries mature sperm from the epididymis toward the ejaculatory duct during ejaculation.
Correct answer: Vas deferens
