Final answer:
The statement indicating the need for further teaching regarding preparations for a non-stress test is 'I'll eat a full meal before coming in', as it may cause sleepiness which can affect the baby's activity patterns during the test.
Step-by-step explanation:
The student is asking about a non-stress test (NST) which is a common prenatal test used to check on a baby's health during pregnancy. The non-stress test measures the baby's heart rate as it moves to ensure the baby's well-being. When reinforcing teaching for a pregnant woman who is to have an NST, the correct guidance would be to drink a glass of water before the test and wear loose clothing, which can make the test more comfortable and help get a clearer ultrasound image. The patient could bring a list of the baby's movements, although this is not essential for the NST itself. However, eating a full meal is not recommended before such a test. This is because after a big meal, some individuals can become sleepy and in the context of an NST, the mother's relaxation can affect the baby's activity patterns. The statement 'I'll eat a full meal before coming in' indicates the need for further teaching about the preparations for a non-stress test.
