A nurse in a provider's office is caring for a client who is at 36 weeks of gestation and scheduled for an amniocentesis. The client asks why she is having an ultrasound prior to the procedure. Which of the following is an appropriate response by the nurse?
"This will determine if there is more than one fetus."
"It assists in identifying the location of the placenta and fetus."
"This is a screening tool for spina bifida."
"It is useful for estimating fetal age."
The Correct Answer is B
Choice A: An ultrasound can indeed determine the number of fetuses if a client is carrying multiples, but this is not the primary reason for performing an ultrasound before amniocentesis.
Choice B: An ultrasound is typically done before an amniocentesis to visualize the location of the placenta and fetus. This information is important to ensure that the amniocentesis needle is safely inserted away from the placenta and the fetus.
Choice C: The primary purpose of an amniocentesis is to obtain a sample of amniotic fluid to screen for genetic conditions, not specifically for spina bifida.
Choice D: Fetal age can be estimated through an ultrasound, but this is not the primary reason for performing an ultrasound before an amniocentesis. The main goal of the procedure is to obtain a sample of amniotic fluid for genetic testing.

Correct Answer is C
Explanation
The correct answer is: c. 42022
Choice A: 40122
Reason: This choice is incorrect because it indicates 4 pregnancies (correct), 0 term births (correct), 1 preterm birth (correct), 2 abortions (correct), but 2 living children (incorrect). The client has 2 living children, which is correct, but the term and preterm counts are not accurate.
Choice B: 20020
Reason: This choice is incorrect because it indicates 2 pregnancies (incorrect), 0 term births (correct), 0 preterm births (incorrect), 2 abortions (correct), and 0 living children (incorrect). The client has had 4 pregnancies, 1 preterm birth, and 2 living children.
Choice C: 42022
Reason: This choice is correct. It indicates 4 pregnancies (current pregnancy, elective abortion, twins, spontaneous abortion), 0 term births, 2 preterm births (twins at 36 weeks), 2 abortions (elective at 9 weeks, spontaneous at 15 weeks), and 2 living children (twins).
Choice D:
The GTPAL system is used to assess a client's obstetric history:
- G (Gravida): The total number of pregnancies, including the current one.
- T (Term births): The number of pregnancies carried to at least 37 weeks.
- P (Preterm births): The number of pregnancies delivered between 20 and 36 weeks, 6 days.
- A (Abortions): The number of pregnancies ending before 20 weeks (spontaneous or elective).
- L (Living children): The number of children currently alive.
For this client:
G (Gravida): 4 (one elective abortion, one twin pregnancy, one spontaneous abortion, and the current pregnancy).
- T (Term births): 0 (the twin pregnancy was delivered at 36 weeks, which is preterm).
- P (Preterm births): 1 (twins delivered at 36 weeks count as one preterm birth).
- A (Abortions): 2 (one elective abortion at 9 weeks, one spontaneous abortion at 15 weeks).
- L (Living children): 2 (the twins).
Thus, the GTPAL for this client is 4-0-1-2-2.
Correct Answer is C
Explanation
Choice A: At 7 cm dilation, the client is in active labor, and assisting her into a more comfortable position may not be appropriate at this stage. It is essential to observe for signs of impending birth and assess the progress of labor.
Choice B:Crowning is assessed only once full dilation occurs. At 7 cm, this is premature and distracts from interventions that prevent injury from early pushing.
Choice C:Panting or blowing helps suppress the urge to push until full dilation, protecting the cervix and reducing complications. This is the evidence-based intervention recommended in labor management guidelines.
Choice D: While emptying the bladder is generally recommended during labor to provide more room for the baby to descend, the client's current urge to push suggests that the baby is likely in a lower position, and it might not be safe or feasible to move the client to the bathroom.
