The placenta provides for exchange of nutrients and waste products between the fetus and mother (Lewis, S.,2011). .The placenta is a temporary vital organ. About five days after fertilization the placenta will attach itself to the woman’s uterus latching to the umbilical cord; it is fully functioning by 13 weeks of pregnancy. The umbilical cord contains two arteries and a vein. The woman and the baby cells make up the placenta. The placenta handles producing pregnancy essential hormones such as human chorionic gonadotropin (HCG), estrogen, progesterone, and relaxin. It acts as the baby’s lungs, kidneys, liver, digestive system and immune system during pregnancy. During pregnancy, the placenta defends the baby against infections by not allowing …show more content…
The heartbeat will begin beating at the start of the fourth week. The most critical part of the cardiac development in fetal development is in days twenty to fifty post fertilization. There are two shunts in the fetal developing heart. Lungs develop late in the fetus, so pulmonary vessels become confined in their capacity making resistance high. There is a straightforward connection with the right and left atria in that the blood from the right atrium travels directly to the left atria by use of the foramen ovale and then goes in the vicinity of the pulmonary circulation system. The ductus arteriosus maneuvers blood from the pulmonary artery to the aorta. Blood is then sent to the heart muscle and brain from the aorta. The blood will then go back to the right atrium of heart passing through the superior vena cava. The majority of the blood goes around the lungs through the ductus arteriousus to the aorta. Circulation of the lower body is furnished by the blood that passes through the ductus arteriosus. There will be two-thirds of the blood that will cut through the foramen ovale; only one-third of the blood will pass conclude in the right ventricle near the lungs. Blood that enters the umbilical arteries then flows into the placenta. The mother’s circulatory system can contain carbon dioxide and waste products; meanwhile, the fetus’ blood has released nutrients …show more content…
Any pregnancy lasting 37-40 weeks is considered a full term pregnancy. Prenatal care should begin soon as a pregnancy test has been confirmed. Prenatal care drastically reduces infant and maternal morbidity rates by early detection and treatment of potential problems (RN Maternal newborn nursing-Review Module ed, 2013). A majority of birth defects occur between 2 and eight weeks gestation. As a registered nurse, I would complete a health history on the patient that will include when was the patient last period, does the patient have children or been pregnant before, the patient height and pre-pregnancy weight, medications that the patient is taking both prescriptions and over I the counter, allergies, any drug use, nutritional status, surgery history, preexisting disease history such as hypertension, diabetes, seizures. I would complete a physical assessment of the expected mother. I would listen to the fetal heart rate. I know that the normal range for a fetal heart rate is 120-160 beats per minute. I will listen to the fetal heart rate by using an ultrasonic Doppler if the patient is at least eight weeks pregnant. If the patient is further than sixteen weeks, I will use the fetoscope to listen to the heart rate. Fetal heart rate can help determine the gestational age and fetal well-being. I will then check the height of the patient fundus; measuring from the symphysis pubis up to the uterine fundus. Measuring the fundal
