The following are probable signs of pregnancy, except?
Deepening pigmentation
Abdominal enlargement
Ballottement
Positive pregnancy test result
The Correct Answer is A
A. Deepening pigmentation, such as changes in the skin like melasma or linea nigra, is considered a presumptive sign of pregnancy, as it is subjective and not specific to pregnancy alone.
B. Abdominal enlargement is a probable sign of pregnancy as it is more objective and can be caused by the growing uterus. However, it may also occur due to other conditions, such as tumors or fluid accumulation.
C. Ballottement, a sensation felt when the fetus rebounds after being pushed gently, is a probable sign of pregnancy due to its reliance on the presence of a fetus.
D. A positive pregnancy test result is a probable sign because it detects hCG levels, which are strongly associated with pregnancy but may also be elevated in other conditions.

Correct Answer is C
Explanation
A. Decreasing fluid intake, especially during pregnancy, is not advisable as it can lead to dehydration and other complications.
B. While urinary frequency varies between individuals, it follows predictable patterns during pregnancy, influenced by hormonal and anatomical changes.
C. Increased urinary frequency is common in the first trimester due to hormonal changes and uterine growth but typically decreases by the second trimester. It often returns in the third trimester when the enlarging uterus exerts pressure on the bladder.
D. Poor bladder tone is not a standard explanation for continued urinary frequency during pregnancy; hormonal and anatomical factors are the primary causes.
Correct Answer is A
Explanation
A. Women have all of their ova at birth. Oogenesis, the process of egg development, occurs in the fetus, and women are born with all the eggs (ova) they will ever have. The number of eggs decreases over time.
B. Women make fewer ova as they age is correct in a sense, but the statement is misleading because the number of eggs actually decreases after birth, not through an ongoing process of "making fewer."
C. Ova production begins at birth and continues until puberty is incorrect. Ova are formed during fetal development, but no new eggs are produced after birth.
D. New ova are made every month from puberty to climacteric is incorrect. While ova mature and are released monthly during a woman's reproductive years, they are not newly made each month. The ovary contains a finite number of immature eggs at birth.
