A client presents to the clinic with complaints of nausea and amenorrhea and reports that she obtained a positive result on a home pregnancy test. Which component of the history is most indicative of pregnancy?

Amenorrhea

Explanation:

This is a clinical condition in which  there is absence of  menstruation,or there is seizure of the menstrual cycle,therefore this condition is refer to seizure of menstruation.

When it occurs in a girl who has reached puberty,but failed to experience menstruation it is called -primary amenorrhea.However,when this occurs in an adult who used to menstruate for a period of 3 months and above it is called secondary amenorrhea,

In either cases  it is usually due to failure of the ovaries to produce eggs-that is the woman failed to ovulate.This may be due to hormonal imbalance from the pituitary gland,or the malfunction in the CNS.I t may also arise from the problem with the female reproductive system,

Since menstruation is caused my failure of the ovum to be implanted on the endometrium,leading to the collapse of the endometrium,and the flow of this together with ovum as blood.Therefore,if the ovaries could not produce ovum,no implantation will take place does the endometrium will not  prepared to shed it walls.No menstruation occurs.  

Therefore this is usually refers to  possible indicator  of the pregnancy.This is because when a woman is pregnant,she can't not ovulate,thus absence of menstruation is a possible indicator of pregnancy.
