A nurse is calculating a client's expected date of birth using Nägele's rule. The client tells the nurse that her last menstrual cycle started on November 27th. Which of the following dates is the client's expected date of birth?

The correct answer is D.

A. Maintain the client NPO throughout the procedure: It is not necessary to maintain the client NPO (nothing by mouth) for a nonstress test. The test primarily involves monitoring fetal heart rate in response to the baby's movements and does not require fasting.

B. Place the client in a supine position: Placing the client in a left lateral position is often preferred for NST to optimize uterine blood flow and fetal oxygenation. The supine position can compromise blood flow to the uterus and is generally avoided, especially in later pregnancy.

C. Instruct the client to massage the abdomen to stimulate fetal movement: While the goal of the NST is to monitor fetal movements, instructing the client to actively stimulate fetal movement through abdominal massage is not a standard part of the procedure. Fetal movements should occur naturally.

D. Instruct the client to press the provided button each time fetal movement is detected: This is the correct action. During a nonstress test, the client is typically provided with a button to press whenever she feels fetal movement. This helps correlate fetal movements with changes in the fetal heart rate on the monitor, providing valuable information about the baby's well-being.

Choice A Reason:

"You can miss your period for several other reasons. Describe your typical menstrual cycle." This response acknowledges that a missed period can result from various factors other than pregnancy, such as stress, changes in weight, hormonal fluctuations, or certain medical conditions. Understanding the client's typical menstrual cycle can help the nurse gather more information about potential reasons for the late period.

Choice B Reason:

"If you have been sexually active and haven't used protection, it is likely that you are pregnant. “This response assumes pregnancy without exploring other possibilities or the client's individual situation.

Choice C Reason:

"Let's check to see if you have any other signs of pregnancy. Have you noticed any abdominal enlargement yet?" While considering other signs of pregnancy is reasonable, focusing on abdominal enlargement may not be the most accurate early indicator, and it's essential to explore a broader range of symptoms.

Choice D Reason:

"Because you have missed your period, you should try taking a home pregnancy test before you start worrying. "While suggesting a home pregnancy test is reasonable, it may be more beneficial to gather additional information about the client's menstrual cycle and potential symptoms before jumping directly to a test.
