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 A
Explanation
A. Cries vigorously when stimulated:
Explanation: Vigorous crying is a positive sign in a newborn. It indicates that the baby is responsive, breathing effectively, and is capable of establishing the necessary air exchange.
B. A positive Babinski reflex:
Explanation: The Babinski reflex is a normal reflex in infants where the toes spread out when the sole of the foot is stimulated. While it is a normal reflex in newborns, it might not necessarily indicate the immediate transition to extrauterine life.
C. Heart rate of 220 beats/minute:
Explanation: A heart rate of 220 beats per minute in a newborn is higher than the normal range. It could be a sign of tachycardia, and this finding might require further evaluation by healthcare providers.
D. Flexion of all four extremities:
Explanation: Flexion of extremities is a normal response in a newborn, but it might not specifically indicate successful transition. It's a common response seen in healthy newborns.
Correct Answer is D
Explanation
A. Review the fetal heart rate pattern: Checking the fetal heart rate (FHR) pattern is crucial during labor to ensure the baby is tolerating labor well and there are no signs of fetal distress. However, when the client expresses a need to use the bathroom, this may not be the immediate action required.
B. Check the pH of the vaginal fluid: Checking the pH of the vaginal fluid is not typically an initial action when a laboring client expresses a need to go to the bathroom. Monitoring the pH may be relevant for various reasons, but it's not a primary consideration in this context.
C. Determine cervical dilation: The initial examination revealed the cervix was 3 cm dilated. While reassessing the cervical dilation could provide information about the progress of labor, it may not be the most immediate action needed when the client wants to use the bathroom.
D. Palpate the client's bladder: This is the most relevant action when a laboring client expresses a desire to go to the bathroom. Palpating the bladder can help determine if it's full, which is important because a full bladder might impede labor progress or cause discomfort during contractions.
