The clinic nurse is obtaining a health history on a newly pregnant patient. Which is an indication for fetal diagnostic procedures if present in the health history?

Correct Answer: A

Rationale: The correct answer is A, maternal diabetes. Maternal diabetes increases the risk of fetal anomalies, so fetal diagnostic procedures may be indicated for early detection. Weight gain, maternal age over 30, and previous infant weight do not necessarily indicate a need for fetal diagnostic procedures. Weight gain and older age are common in pregnancy, while the previous infant's weight alone is not a direct indicator of fetal health.

Correct Answer: A

Rationale: The correct answer is A: Safety of the fetus. Expectant parents prioritize the safety of their unborn child above all else. Ensuring that the fetal diagnostic testing is safe for the fetus is crucial in making informed decisions about the pregnancy. Other choices are less important as safety directly impacts the well-being of the fetus, while the duration, cost, and physical discomfort are secondary considerations in comparison.

Correct Answer: D

Rationale: The correct answer is D because being positive for group B Streptococcus can increase the risk of infection during transcervical chorionic villus sampling, making it a contraindication. Rh-negative mother (A) and maternal age younger than 35 years (C) are not contraindications. Gestation less than 15 weeks (B) is not a strict contraindication but may affect the accuracy of the procedure.

Correct Answer: B

Rationale: The correct answer is B: Monitoring uterine activity. After an amniocentesis, it is crucial to monitor uterine activity to detect any signs of preterm labor or uterine contractions. This helps in identifying any potential complications early on and ensures prompt intervention if needed. A: Pushing fluids by mouth is important for hydration but not directly related to optimal nursing care after an amniocentesis. C: Placing the patient in a supine position for 2 hours is not recommended as it may increase the risk of hypotension and discomfort for the patient. D: Applying a pressure dressing to the puncture site is not necessary after an amniocentesis as the risk of bleeding is minimal and pressure dressings may increase the risk of infection.

Correct Answer: D

Rationale: The purpose of initiating contractions in a contraction stress test (CST) is to apply a stressful stimulus to the fetus to assess its response to stress, mimicking the stress of labor. This helps evaluate fetal well-being by monitoring the fetal heart rate during contractions. A: Increasing placental blood flow is not the primary purpose of CST. B: Identifying fetal acceleration patterns is not the main goal of CST. C: Determining the degree of fetal activity is not the primary objective of CST. The correct answer is D as it reflects the main purpose of initiating contractions in a CST.
