The vulva consists of which structure?
- A. Labia majora, minora, clitoris, mons pubis, and vestibular glands
- B. Penis, scrotum, and prostate gland
- C. Internal female structures, including the uterus and ovaries
- D. Openings of the urethra and vagina
Correct Answer: A
Rationale: The correct answer is A because the vulva comprises the labia majora, labia minora, clitoris, mons pubis, and vestibular glands. The labia majora and minora are outer and inner folds of skin, the clitoris is a sensitive organ, the mons pubis is a fatty area overlying the pubic bone, and the vestibular glands secrete lubrication. Choices B, C, and D are incorrect because they do not accurately represent the structures of the vulva. B refers to male reproductive structures, C to internal female organs, and D to specific openings rather than the entire vulva.

Correct Answer: A
Rationale: At puberty, the ovaries become functional and produce mature ova.
Amniotic fluid index of 18 cm in the 3rd trimester is interpreted as:
- A. Hydrops fetalis
- B. Normal amniotic fluid volume
- C. Reduced amniotic fluid volume
- D. Increased amniotic fluid volume
Correct Answer: B
Rationale: The correct answer is B: Normal amniotic fluid volume. An amniotic fluid index of 18 cm in the 3rd trimester is considered within the normal range (5-25 cm). This level indicates adequate amniotic fluid for fetal development and is not indicative of hydrops fetalis (A), reduced amniotic fluid volume (C), or increased amniotic fluid volume (D). It is crucial to monitor amniotic fluid levels as deviations from the normal range can impact fetal well-being.
