Correct Answer is ["B","C","E"]

Explanation

A) Incorrect- Dry, cracked skin is not typically associated with a newborn born at 43 weeks of gestation. It's more common in post-term babies.
B) Correct - Hypotonia (low muscle tone) is a possible finding in post-term newborns due to the aging placenta and potential decrease in amniotic fluid.
C) Correct - Excessive lanugo (fine, downy hair) is more likely to be present in post-term babies as they have less vernix to protect their skin.
D) Incorrect- Absent vernix might be more characteristic of a post-term newborn, but its presence or absence varies widely.
E) Correct - Long, hard nails can be a characteristic of post-term babies, as they have had more time for nail growth in the womb.

A. "You will have a group B strep culture at 36 weeks of gestation." B. "You will have to produce a clean catch urine specimen every 2 months." C. "You will have a maternal serum alpha-fetoprotein screening at 6 weeks of gestation. D. "You will have a screening for gestational diabetes at 12 weeks of gestation."

Correct Answer is A

Explanation

A) Correct - Group B streptococcus (GBS) screening is typically performed around 36 weeks of gestation to identify colonization. It helps determine whether antibiotic prophylaxis is necessary during labor to prevent transmission to the newborn.
B) Incorrect- Producing a clean catch urine specimen every 2 months is not a standard recommendation during pregnancy. Urine testing is common but does not usually occur this frequently.
C) Incorrect- Maternal serum alpha-fetoprotein screening is typically done around 15-20 weeks of gestation, not 6 weeks.
D) Incorrect- Screening for gestational diabetes typically occurs between 24 and 28 weeks of gestation, not 12 weeks.
