![]() Fundal height is measured from the fundus to the pubic symphysis (middle anterior pelvis, above the vulva). The fundus is not just a word that some nursing students and nurses find hilarious it's the topmost part of the uterus. ![]() Beginning at 18 weeks of pregnancy, the gestational age of the pregnancy should correlate to the fundal height in centimeters plus or minus two weeks What is the fundus? Fundal height measurementĭuring 18 - 22 weeks of pregnancy, the patient will begin to need a fundal height assessment. By the time the patient has reached the second trimester of pregnancy, their ultrasounds will usually be abdominal rather than transvaginal. Ultrasoundĭuring 18 - 22 weeks of pregnancy, a patient will have an ultrasound as a standard part of prenatal care and to check for abnormalities that may require additional testing. 18 - 22 weeks (month 5)ĭuring 18 - 22 weeks of pregnancy, the patient will have an ultrasound to assess for any fetal abnormalities, and the fundal height will start to be measured during this time. If a patient does not have higher risk, this test happens later. If a patient is at high risk for gestational diabetes, they may be tested during 14 - 18 weeks of pregnancy with an oral glucose tolerance test. Amniocentesisĭuring 14 - 18 weeks of pregnancy, if a patient has an abnormal result on their MSAFP test, they may require an amniocentesis, which is an invasive procedure wherein some amniotic fluid is removed from the uterus with a long needle and tested for genetic abnormalities. MSAFP testingĭuring 14 - 18 weeks of pregnancy, the patient may get a maternal serum alpha-fetoprotein (MSAFP) test, which is a test for genetic abnormalities like neural tube defects and Down syndrome. 14 - 18 weeks (month 4)ĭuring 14 - 18 weeks of pregnancy, the patient will get MSAFP testing done, followed up with amniocentesis if anything abnormal is found, and a gestational diabetes screening. Starting in the second trimester, the fetal heart rate will be assessed via doppler and fetal vital signs and weight will be obtained at each visit. The second trimester of pregnancy is from week 13 - 24 (months 4, 5, and 6) and there will be some important visits during this time. You can check out Part 4: Maternal Teaching: Nutrition/Weight Gain, Warning Signs, Unpleasant Side Effects which follows along with our flashcards. In our Maternity Nursing Flashcards we cover patient teaching in detail. This includes nutritional guidance, weight gain, warning signs of complications, and expected side effects. First trimester maternal patient teachingĭuring the first trimester visit(s), you will give the pregnant patient some patient teaching about what to expect during their pregnancy. Catching an ectopic pregnancy in the earliest stage of pregnancy is crucial to prevent harm to the patient. Transvaginal means across or through the vagina, so the ultrasound device is placed inside the vagina, as opposed to an abdominal ultrasound wherein the device is against the abdomen.Ī transvaginal ultrasound makes it much easier to get detailed imagery of the uterus and fallopian tubes than an abdominal ultrasound. During the first trimester visit(s), the patient may get a transvaginal ultrasound to confirm pregnancy, site of implantation (to ensure it's a safe pregnancy, not ectopic). First trimester visit labs and diagnosticsĭuring the first trimester visit(s), the patient will have some important labs and diagnostic testing done, including the following:Ī transvaginal ultrasound is a test that gives a view of the patient's uterus, ovaries, fallopian tubes, cervix, and the surrounding area. Check out our next video to learn more! Calculating estimated date of deliveryĭuring the first trimester visit(s), the provider or care team will calculate the patient's estimated date of delivery-when baby is expected to arrive! One useful way of calculating this is with Naegele's rule. There is a special acronym for this, GTPAL. Obstetric historyĭuring the first trimester visit(s), the care team will gather the patient's obstetric history, meaning how many pregnancies and of what type. Until approximately 28 weeks, the pregnant patient will have monthly visits. A patient may have more than one visit in their first trimester, but it depends on when they realize that they may be pregnant.ĭuring the first trimester visit, the provider will obtain the pregnant patient's obstetric history, calculate the estimated date of delivery, run important laboratory tests, perform a transvaginal ultrasound, and give the patient some initial maternal teaching. ![]() The first trimester of pregnancy is the first 12 weeks (months 1, 2, and 3) and the first prenatal visit will take place during this time.
