What items should be included in a comprehensive checklist for a patient's first prenatal visit?

First Prenatal Visit Checklist

A comprehensive first prenatal visit should include laboratory testing, infectious disease screening, genetic counseling, immunization review, psychosocial assessment, and detailed counseling on nutrition and lifestyle modifications. 1

Laboratory Testing and Blood Work

Obtain a complete blood count to screen for anemia, which requires treatment if present. 1, 2

• Blood type and Rh screen to identify Rh-negative status requiring RhoGAM administration and detect antibodies causing hemolytic disease 2
• Urinalysis and urine culture for asymptomatic bacteriuria screening 2
• Rubella immunity status to assess susceptibility and need for postpartum vaccination 3, 2
• Syphilis screening as untreated syphilis causes significant fetal morbidity 3, 2
• Hepatitis B surface antigen to identify chronic infection and prevent vertical transmission 3, 2
• HIV testing to initiate antiretroviral therapy if positive and reduce transmission risk 3, 2
• Gonorrhea and chlamydia screening as indicated 3
• Cervical cytology if due per routine screening guidelines 3

Medical and Reproductive History Assessment

Review previous pregnancy complications including infant death, fetal loss, birth defects, low birth weight, and preterm birth to identify recurrence risks. 3, 1

• Screen for chronic medical conditions including diabetes, hypertension, thyroid disease, rheumatic heart disease, thromboembolism, and autoimmune diseases 3, 1
• Assess thyroid function particularly in patients with hypothyroidism requiring medication adjustment 2
• Review current medications and immediately discontinue FDA pregnancy category X medications (isotretinoin, warfarin) and evaluate category D medications unless maternal benefits outweigh fetal risks 3, 1
• Document over-the-counter medications, herbs, and supplements 3

Genetic Screening and Counseling

Offer genetic carrier screening based on ethnicity, family history, and maternal age to identify potential genetic disorders. 3, 1

• Cystic fibrosis carrier screening should be offered as indicated 3
• Discuss management of known genetic disorders such as phenylketonuria and thrombophilia 3
• Assess risk of chromosomal disorders based on family history, ethnic background, and age 3

Immunization Status and Updates

Review immunization history and update as needed with hepatitis B, rubella, varicella, Tdap, human papillomavirus, and influenza vaccines. 3

• Tdap vaccine should be administered at 27-36 weeks gestation to provide infant protection against pertussis 1, 4
• Influenza vaccination during flu season prevents maternal and fetal complications 1
• Rubella and varicella vaccines should be given postpartum if seronegative, not during pregnancy 4

Nutritional Assessment and Supplementation

Initiate folic acid supplementation (400-800 mcg daily) immediately, as it reduces neural tube defects but only if started before neural tube closure at 6 weeks. 3, 1, 5

• Assess body mass index and target prepregnancy BMI of 19.8-26.0 kg/m² through exercise and nutrition 3, 1
• Counsel on consuming five servings of fruits and vegetables daily (two fruits, three vegetables) 3, 1
• Prescribe daily prenatal multivitamin containing folic acid 3
• Screen for nutritional risks using anthropometric (BMI), biochemical (anemia), clinical, and dietary assessments 3

Substance Use and Behavioral Screening

Screen for tobacco, alcohol, and drug use using validated tools such as CAGE or T-ACE questionnaires. 3, 2

• Counsel complete abstinence from alcohol, tobacco, and recreational drugs to minimize maternal and fetal risks 1
• Use the five A's approach for smoking cessation (Ask, Advise, Assess, Assist, Arrange) 3
• Discourage risky behaviors including douching and not wearing seatbelts 3

Psychosocial Screening

Screen for depression, anxiety, domestic violence, and major psychosocial stressors using validated instruments. 3, 2

• Universal screening for intimate partner violence should be performed 2, 5
• Assess food insecurity as social determinants of health impact outcomes 5
• Evaluate major life stressors that may affect pregnancy 3

Environmental and Occupational Exposure Assessment

Counsel about possible toxins and teratogenic agent exposure at home, in the neighborhood, and at work including heavy metals, solvents, pesticides, endocrine disruptors, and allergens. 3

• Review Material Safety Data Sheets for workplace exposures 3
• Consult local teratology information specialist as needed 3

Reproductive Life Planning

Discuss the patient's reproductive life plan including whether she plans additional children and desired spacing between pregnancies. 3

• Promote family planning based on reproductive goals 3
• Discuss effective contraceptive use and emergency contraception for women not planning pregnancy 3

Physical Examination Components

Perform baseline blood pressure measurement and establish ongoing monitoring protocol, as hypertensive disorders can develop throughout pregnancy. 2

• Document baseline weight for tracking appropriate gestational weight gain 2
• Perform comprehensive physical examination including cardiovascular and thyroid assessment 3

Counseling on Pregnancy-Related Topics

Provide education on normal pregnancy symptoms, warning signs requiring immediate attention, and preparation for childbirth. 1

• Discuss healthy behaviors including nutrition, exercise, safe sex practices, and dental flossing 3
• Counsel on preventing TORCH infections (toxoplasmosis, other, rubella, cytomegalovirus, herpes) 3
• Promote breastfeeding through structured educational programs 3, 6

Special Considerations for High-Risk Conditions

Women with preexisting diabetes require A1C <6.5% prior to conception and multidisciplinary team management including endocrinology and maternal-fetal medicine. 1

• Target blood pressure <140/90 mmHg using pregnancy-safe medications in women with chronic hypertension 1, 5
• Screen for periodontal disease as treatment decreases preterm delivery risk 3, 5

Common Pitfalls to Avoid

The evidence shows that many prenatal visits fail to adequately cover psychosocial screening, environmental exposures, and detailed counseling topics despite guideline recommendations. 7 Ensure systematic coverage of all recommended topics rather than focusing only on traditional medical assessments. 7 Early initiation of prenatal care (at 10 weeks or earlier) significantly improves outcomes, so emphasize the importance of early presentation for future pregnancies. 5
