Absence of menstruation
- A. Rhinorrhea
- B. Amenorrhea
- C. Menorrhagia

Rhinorrhea (A) is the medical term for a runny nose, unrelated to menstruation. Menorrhagia (C) is excessive menstrual bleeding, the opposite of absence of menstruation. Leucorrhea (D) is a vaginal discharge, not related to the absence of menstruation. Therefore, B is the correct answer as it directly addresses the absence of menstruation.

The failure of a testes to descend is referred to as _____.
- A. inguinal hernia
- B. strangulated hernia
- C. vaginal process
- D. cryptorchidism
Correct Answer: D
Rationale: The correct answer is D: cryptorchidism. This is because cryptorchidism specifically refers to the failure of one or both testes to descend into the scrotum. It is a common condition in newborns and can lead to complications if not treated.
A: Inguinal hernia is the protrusion of abdominal contents through the inguinal canal, not related to testes descent.
B: Strangulated hernia occurs when the blood supply to the herniated tissue is cut off, not related to testes descent.
C: Vaginal process is a structure involved in testicular descent but does not describe the failure of testes descent itself.
Summary:
Cryptorchidism is the correct term for undescended testes, while the other options are unrelated conditions.
What is the final stage of labour?
- A. Dilation of the cervix.
- B. Delivery of the infant.
- C. Contraction of the uterus.
- D. Delivery of the placenta
Correct Answer: D
Rationale: The final stage of labor is the delivery of the placenta. This occurs after the baby is born. The placenta is essential for providing nutrients and oxygen to the baby during pregnancy, but once the baby is born, it needs to be expelled from the mother's body. This process is crucial to prevent postpartum complications.
A: Dilation of the cervix occurs in the first stage of labor.
B: Delivery of the infant happens in the second stage of labor.
C: Contraction of the uterus is a continuous process throughout labor but does not signify the final stage.
In summary, the correct answer is D because it represents the final step in the labor process, while the other options pertain to earlier stages of labor.

Patella is a
- A. Irregular bone
- B. Short bone
- C. Sesamoid bone
- D. Flat bone
Correct Answer: C
Rationale: The patella is a sesamoid bone located within the tendon of the quadriceps femoris muscle.

It is not irregular (A), short (B), or flat (D) as it does not fit the structural characteristics of those bone types. Therefore, the correct answer is C.
If a cell has 46 chromosomes at the beginning of mitosis, determine the number of chromatids at
- B. 23 chromatids
- C. 46 chromatids
- D. 92 chromatids
Correct Answer: D
Rationale: The correct answer is D: 92 chromatids. In mitosis, each chromosome consists of two sister chromatids. Since the cell begins with 46 chromosomes, there are a total of 92 chromatids present. This is because each chromosome duplicates during the S phase of interphase, resulting in two identical sister chromatids held together by a centromere. Therefore, the total number of chromatids in the cell at the beginning of mitosis is twice the number of chromosomes. Choices A, B, and C are incorrect because they do not account for the duplication of chromatids that occurs during the cell cycle.
