A primipara at 20-weeks gestation is scheduled for an ultrasound. In preparing the client for the procedure, the nurse should explain that the primary reason for conducting this diagnostic study is to obtain which information?
Chromosomal abnormalities
Sex and size of the infant
Lecithin-sphingomyelin ratio
Fetal growth and gestational age.
The Correct Answer is D
A. Chromosomal abnormalities:
While an ultrasound can sometimes identify structural abnormalities, it's not the primary tool for detecting chromosomal abnormalities. Genetic testing or procedures like amniocentesis are more specific for this purpose.
B. Sex and size of the infant:
An ultrasound is indeed used to determine the sex of the baby and assess its size and growth.
C. Lecithin-sphingomyelin ratio:
The lecithin-sphingomyelin ratio is typically assessed in tests related to fetal lung maturity, which is not the primary purpose of a routine ultrasound.
D. Fetal growth and gestational age:
This is one of the primary purposes of a routine ultrasound during pregnancy. It helps evaluate the baby's growth and ensures it aligns with the expected gestational age.

Correct Answer is B
Explanation
A. Document the findings in the record: Documenting the findings is important, but it doesn't address the potential issue of hypoglycemia.
B. Obtain a heel stick blood glucose level: This is the most appropriate action given the signs presented. A low blood glucose level can be a critical issue in newborns and requires prompt evaluation and management.
C. Place a pulse oximeter on the heel: While oxygen saturation monitoring is valuable in certain situations, it may not be the priority in this case where hypoglycemia is suspected.
D. Swaddle the infant in a warm blanket: While maintaining warmth is important, especially if the baby is hypothermic, addressing the potential hypoglycemia takes precedence.
Correct Answer is B
Explanation
A. After ceasing breastfeeding, the diaphragm should be resized: Breastfeeding can affect vaginal lubrication and elasticity. It might be advisable to have the diaphragm refitted after childbirth and after breastfeeding stops. However, this choice doesn't directly address the current situation.
B. Use an alternate form of contraception until a new diaphragm is obtained: This is a reasonable suggestion. Using a diaphragm that was fitted before pregnancy might not offer adequate protection due to potential changes in the cervix's size or shape after childbirth.
C. If no more than 20 pounds were gained during pregnancy, the diaphragm is safe to use: Weight gain during pregnancy can affect the size and shape of the vagina and cervix. However, specifying a particular weight gain as a safety criterion for using the diaphragm isn't entirely accurate.
D. Avoid intercourse during ovulation until the size of the diaphragm has been evaluated: This is a cautious approach. Waiting until the diaphragm size is confirmed by a healthcare professional could be prudent to ensure the correct fit and effectiveness.
