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.

Answer and Explanation

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. Obtain blood and urine for prenatal screens.
This choice is important because it allows the nurse to assess the client's overall health, screen for infections, and identify any potential risks or complications that may impact the pregnancy.

B. Explain common complications of pregnancy.
While educating the client about common complications is valuable, it may not address the immediate need to screen for specific infections or assess the client's current health status. This information can be covered during prenatal education sessions.

C. Obtain baseline blood pressure and weight.
This is a routine part of prenatal care and is important for monitoring the client's health throughout pregnancy. However, if the client has a history of syphilis, obtaining specific prenatal screens (including for syphilis) would be a more targeted and immediate action.

D. Schedule prenatal visits to occur monthly.
Scheduling regular prenatal visits is essential for monitoring the progression of the pregnancy. However, addressing the specific health concerns and obtaining necessary screens take precedence during the initial visit, especially considering the client's history of syphilis.

A. Sleep deprivation. B. Fluid volume excess C. Nausea and vomiting D. Risk for infection.

Correct Answer is B

Explanation

A. Sleep deprivation:

While sleep is important for overall well-being, it may not be the top priority in this case. Fluid volume excess, given the client's cardiac history, poses a more immediate threat to health.

B. Fluid volume excess:

Clients with heart damage are prone to heart failure, and managing fluid balance is crucial. Excess fluid can worsen cardiac function, making this the priority concern.

C. Nausea and vomiting:

While nausea and vomiting are significant concerns, they might not be as directly related to the client's cardiac history as fluid volume excess. However, if severe, it could contribute to fluid imbalance.

D. Risk for infection:

Infection is a concern for postpartum clients, but in this case, the client's history of rheumatic fever and heart damage takes precedence. The priority is to prevent complications related to heart failure.
