In this article, we cover maternal teaching on nutrition, weight gain, calorie intake, what to avoid, warning signs, and unpleasant side effects. These are the topics that nurses need to be able to teach pregnant patients about.
Nutrition
During pregnancy, certain macronutrients and vitamins are required to sustain the health of the patient and their baby. This includes folic acid, protein, iron, calcium, vitamin D, and fluids.
Maternity Nursing - Flashcards
Folic acid
Pregnant patients should increase folic acid to 600 mcg per day. Folic acid prevents neural tube defects. Read more on folic acid.
Protein
Protein promotes tissue growth and helps build muscle (e.g., the tissue and muscles of the baby!). Pregnant patients should increase their protein intake to 60 g per day.
However, patients who have phenylketonuria (PKU) need to follow a strict low-phenylalanine (low-protein) diet and have phenylalanine levels monitored through pregnancy.
Iron
Pregnant patients should increase their iron intake to 27 mg per day. Iron helps with production of red blood cells to supply oxygen to the fetus. Patients can take an iron supplement (ferrous sulfate) with vitamin C to increase absorption.
Calcium
Calcium helps formation of fetal bones and teeth; pregnant patients should increase intake of calcium to 1,000 mg per day.
Vitamin D
Vitamin D promotes the absorption of calcium. Patients who are pregnant should increase their vitamin D intake to 600 IU per day.
Fluids
Patients should get 2 - 3 L of water per day.
Weight gain
Underweight patients should aim to gain between 28 - 40 pounds. For patients of average weight, 25 - 35 pounds, and for overweight patients, 15 - 25 pounds.
In the first trimester, patients should gain 2.2 - 4.4 total. In the second and third trimesters, patients should gain approximately 1 pound a week.
Calorie intake
During the first trimester, pregnant patients should not increase calorie intake. During the second trimester, patients should increase calorie intake by around 340 per day. During the third trimester, patients should increase calorie intake by 450 per day. After delivery when the patient is breastfeeding, they should have a calorie intake that is increased by approximately 450 - 500 per day. These amounts are not cumulative, and the increase is calculated over the patient's baseline caloric intake. For example, if a patient normally consumes 2000 calories a day, according to these guidelines they would consume:
- Pre-pregnancy, the example patient consumes 2000 calories a day.
- First trimester: 2000 calories.
- Second trimester: 2340 calories.
- Third trimester: 2450 calories.
- Breastfeeding: 2450-2500 calories.
What to avoid during pregnancy
During pregnancy, patients should avoid taking medications and supplements unless their provider is aware and confirms the drugs to be safe during pregnancy. Check out our Pharmacology Flashcards for black box warnings on drugs during pregnancy.
Pregnant patients should limit caffeine intake to under 200mg per day. Patients should also avoid fish high in mercury, e.g., albacore tuna—limit to less than 6 ounces a week.
As you probably already know, patients who are pregnant should avoid alcohol, drugs, and smoking. Pregnant patients should also avoid hot tubs/saunas as they can be too hot.
Warning signs during pregnancy
There are some warning signs to watch out for during pregnancy. Patients who experience any of these should contact their provider right away:
- Diarrhea, fever, chills
- Severe abdominal cramping/pain
- Severe vomiting
- Vaginal bleeding
- Decreased fetal activity
Unpleasant side effects of pregnancy
Pregnant patients should be given teaching on the potentially unpleasant side effects they may encounter during pregnancy. Not all patients experience these, but it is good for patients to be aware that they may happen. These include congestion, constipation, epistaxis, fatigue, gingivitis, heartburn, hemorrhoids, nausea/vomiting, urinary frequency, varicose veins, and more.
Read on to find out more about these side effects and what can be done to mitigate them.
Congestion
Patients may become congested during pregnancy. If so, they can try a normal saline spray. Certain antihistamines are appropriate for pregnancy, e.g., Zyrtec.
Constipation
Patients might become constipated during pregnancy. To help combat this, they can increase their fluid and fiber intake.
Epistaxis (nosebleeds)
Epistaxis is a fancy word for a nosebleed, and pregnant patients may get them. To help with this, they can use a humidifier if that's an option available to them.
Fatigue
Patients who are pregnant may become fatigued—creating a person can be exhausting! Patients should take frequent rest periods or naps to help combat fatigue.
Gingivitis
Pregnant patients may get gingivitis (gum disease). To help combat this, patients should practice good dental hygiene, brush with a soft toothbrush, and floss daily.
Heartburn
Patients who are pregnant may get heartburn after eating. To help reduce this, patients can eat small and frequent meals, avoid laying down after meals, and avoid spicy or greasy foods which may exacerbate it.
Hemorrhoids
Patients who are pregnant may get hemorrhoids, which are swollen veins on the anus or rectum. They can be painful and cause bleeding during bowel movements. Patients can take a warm sitz bath (which is sitting in shallow warm water in the tub), and use witch hazel pads as an antiseptic. Patients should avoid straining during bowel movements.
Nausea/vomiting
Patients may experience morning sickness, which is nausea and vomiting, that—surprise!—doesn't always happen in the morning. Patients can try eating some crackers to help settle the stomach before getting out of bed, eat small/frequent meals, and bland foods which may be easier to keep down.
Urinary frequency
Patients who are pregnant have extra pressure on their bladder and so may need to urinate frequently. These patients should pee often, and practice kegel exercise to help decrease stress incontinence.
Varicose veins
Pregnant patients may get varicose veins, which are enlarged and twisted veins that become swollen. To help prevent varicose veins, patients can elevate legs, wear compression socks/stockings, walk often, and avoid prolonged standing.
Other unpleasant side effects of pregnancy
Other unpleasant side effects of pregnancy may include backaches because of new weight distribution, breast tenderness, cramps, and edema (swelling).
