A nurse is caring for a client who is at 12 weeks of gestation during an initial prenatal visit. The client asks, "What is a normal fetal heart rate?" Which of the following ranges should the nurse provide?
110 to 160/min
100 to 110/min
160 to 190/min
80 to 100/min
The Correct Answer is A
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. 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.
Correct Answer is C
Explanation
A. While alcohol consumption in early pregnancy poses significant risks, it is not safe to drink alcohol at any point during pregnancy. There is no safe amount of alcohol that can be consumed without risk to the developing fetus.
B. Although the sentiment is correct in discouraging alcohol use, this response could be seen as judgmental and may not foster a supportive environment for the client.
C. We recommend no alcohol during pregnancy for the best outcomes. This is the correct and evidence-based response. The safest choice for both maternal and fetal health is to avoid alcohol entirely during pregnancy.
D. While alcohol consumption during pregnancy can lead to various issues like fetal alcohol syndrome, it is unlikely to directly cause the baby’s heart to stop beating.
