The nurse is teaching a pregnant client how to perform daily fetal movement counts.
Which instruction must be included in the teaching?
Lie on back when counting kicks.
You can begin counting fetal movements at 8 weeks gestation.
Call healthcare provider if at least 3 movements are not felt over an hour.
Count movements at the same time each day.
The Correct Answer is C
Choice A rationale
Lie on back when counting kicks is incorrect. It is recommended to lie on the side, preferably the left side, as lying on the back can compress major blood vessels and affect circulation to the fetus.
Choice B rationale
You can begin counting fetal movements at 8 weeks gestation is incorrect. Fetal movements are typically felt by the mother starting around 18-20 weeks of gestation, not as early as 8 weeks.
Choice C rationale
Call healthcare provider if at least 3 movements are not felt over an hour. This is an important guideline as decreased fetal movements can indicate potential issues and should be reported to the healthcare provider for further evaluation.
Choice D rationale
Count movements at the same time each day is a good practice but it is not the most critical instruction. While consistency is beneficial, the immediate action for decreased movements is more urgent.

Correct Answer is B
Explanation
Choice A rationale
Blood returning to the right atrium from the pulmonary system is consistent with adult circulation, not fetal circulation. In fetal circulation, blood bypasses the lungs via the ductus arteriosus and foramen ovale since the fetus receives oxygenated blood from the placenta, not the lungs.
Choice B rationale
Blood is returning to the placenta via the umbilical arteries. In fetal circulation, deoxygenated blood is carried from the fetus to the placenta through the umbilical arteries. This is consistent with normal fetal circulation as the placenta is responsible for gas exchange.
Choice C rationale
Blood being shunted to the right side from the left side of the heart is incorrect. In fetal circulation, there is a right-to-left shunt through the foramen ovale, allowing blood to bypass the non-functioning fetal lungs and go directly into systemic circulation.
Choice D rationale
A right-to-left shunt is not seen between the umbilical arteries. Instead, the shunts in fetal circulation are the ductus venosus, ductus arteriosus, and foramen ovale, which help reroute blood away from the fetal lungs and liver.
Correct Answer is A
Explanation
Choice A rationale
At 9 weeks gestation, the primary purpose of an ultrasound is to confirm the presence of a fetal heartbeat, which indicates a viable pregnancy.
Choice B rationale
Chromosomal defects are typically assessed using different tests, such as chorionic villus sampling or amniocentesis, rather than an ultrasound at this early stage.
Choice C rationale
Fetal lung maturity cannot be assessed at 9 weeks gestation because the lungs are not yet developed. This assessment is usually done later in pregnancy if preterm delivery is anticipated.
Choice D rationale
The position of the fetus in utero is not a concern at this early stage of pregnancy. Fetal positioning becomes relevant later in pregnancy, closer to delivery.
