What is the most accurate response from a nurse when a pregnant woman having an ultrasound at 8 weeks of gestation asks if she may learn her expectant child's sex?
We will have to wait until the birth of your child to know for sure
Yes we will be able to tell the sex of your child
No, the sex organs have not yet started to develop
The 10th week is when the external genitalia are visible on ultrasound
The Correct Answer is C
A. It is true that the child’s sex can often be confirmed later in pregnancy, but at 8 weeks, it is typically too early to definitively determine the sex with an ultrasound.
B. At 8 weeks, it is usually not possible to determine the baby’s sex with ultrasound. The external genitalia are not fully developed at this stage.
C. No, the sex organs have not yet started to develop. This is the correct answer. The differentiation of the sex organs begins during the early stages of pregnancy, but they are not visible on ultrasound at 8 weeks.
D. The external genitalia start to become distinguishable a little later in pregnancy, but not as early as the 10th week, making this answer less accurate.

Correct Answer is A
Explanation
A. 110 to 160/min is the normal range for a fetal heart rate at 12 weeks of gestation. The fetal heart rate tends to be higher early in pregnancy and stabilizes within this range by the second trimester.
B. 100 to 110/min is too low for a normal fetal heart rate.
C. 160 to 190/min is above the normal range and may suggest tachycardia, which requires further investigation.
D. 80 to 100/min is too low for a typical fetal heart rate and would be considered bradycardia, which could indicate a concern.
Correct Answer is A
Explanation
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.
