NU576 Unit 7 Journal

Establishing prenatal care at 20 weeks’ gestation for a multiparous patient requires a thorough clinical assessment that balances routine fetal surveillance with targeted maternal risk mitigation. For a 35-year-old pregnant female presenting to establish care following a interstate move, optimal clinical management focuses on evaluating pregnancy-related lower back pain, ordering routine second-trimester diagnostic laboratory screening, delivering immediate fetal alcohol exposure counseling, and initiating close perinatal mental health surveillance given a history of recurrent pregnancy loss and depression.

Patient Demographic and Clinical Profile

Lara Taylor, a 35-year-old female (Encounter #5466525), established prenatal care on October 10, 2023. At 20 weeks’ gestation, she presents for her initial second-trimester evaluation following a recent relocation from Ohio.

Subjective Clinical Evaluation

History of Present Illness (HPI)

The patient presents to establish prenatal care in her new state of residence. She reports no acute gestational complications but identifies persistent lower back pain as her primary physical complaint. She describes the sensation as a localized “tugging” discomfort across her lumbar region that intensifies after prolonged standing and improves significantly with rest. She attributes this to anatomical changes associated with her growing abdomen.

This is her third pregnancy (Gravida 3, Para 0, Abortion 2), with an obstetric history notable for one elective abortion and one spontaneous miscarriage. She is currently taking over-the-counter prenatal vitamins. She discloses past use of escitalopram (Lexapro) for depression, which she discontinued several years ago without subsequent pharmacological management.

Medical, Surgical, and Family History

The patient’s past medical history is significant for two distinct episodes of major depression, both occurring in the context of her prior pregnancy losses. She denies chronic systemic conditions such as hypertension, asthma, or diabetes. Her surgical history includes a dilation and curettage (D&C) procedure performed five years ago following a pregnancy loss.

Family history reveals cardiovascular disease and metabolic risk:

Father: Deceased at age 60 secondary to an acute myocardial infarction.
Mother: Living, diagnosed with type 2 diabetes mellitus 10 years ago.
Brother: Living with no reported chronic medical conditions.

Psychosocial History and Lifestyle Factors

The patient holds a bachelor’s degree and a teaching certificate, currently working as a substitute teacher. She married three months ago and resides with her husband, who is currently unemployed following their recent relocation.

A review of her health behaviors reveals several critical clinical entry points:

Allergies: Documented latex allergy resulting in localized contact dermatitis/rash.
Tobacco Use: Former smoker who smoked one pack per day for several years; successfully quit upon learning of her current pregnancy.
Alcohol Consumption: Discloses drinking one glass of wine nightly throughout her pregnancy.
Substance Use: Denies illicit drug use; reports past recreational use of cannabis and hemp-derived gummies prior to pregnancy.

Comprehensive Review of Systems (ROS)

Systemic review confirms common second-trimester physiological adaptations alongside specific areas requiring targeted counseling:

General: Reports pregnancy-related fatigue and a 12-pound weight gain (155 lbs to 167 lbs). Denies fever or night sweats.
Cardiovascular & Respiratory: Denies chest pain, palpitations, dyspnea, cough, or orthopnea.
Gastrointestinal: Denies nausea, vomiting, hematemesis, or diarrhea. Reports new-onset constipation since entering the second trimester.
Genitourinary & Gynecological: Reports increased urinary frequency consistent with uterine displacement of the bladder. Denies dysuria, hematuria, or abnormal vaginal discharge. Currently sexually active with her spouse.
Musculoskeletal: Reports lower back discomfort with postural strain; denies joint swelling or peripheral motor deficits.
Neurological & Psychiatric: Denies headaches, visual disturbances, dizziness, or focal weakness. Notes a history of perinatal depression. During the examination, the patient demonstrates reduced eye contact and downward gaze when discussing her spouse’s employment status and home dynamic, highlighting a potential need for deeper psychosocial assessment.

Objective Physical Evaluation

Vital Signs and Baseline Measurements

Physical metrics indicate a stable maternal baseline with an elevated body mass index (BMI):

Blood Pressure: 132/64 mmHg
Pulse: 75 beats/minute, regular
Respiratory Rate: 20 breaths/minute
Temperature: 98.0°F (36.7°C)
Height: 5’2″ (62 inches)
Weight: 167 lbs (Pre-pregnancy weight: 155 lbs)
BMI: 30.5 kg/m² (Class I Obesity)

Physical Examination Findings

Physical assessment reveals a healthy, cooperative adult female displaying physiological findings consistent with a normal 20-week pregnancy:

HEENT & Skin: Normocephalic, atraumatic. Mucous membranes moist; teeth intact without obvious caries. Pupils equal, round, and reactive to light (PERRLA). Skin is dry, intact, and free of rashes, petechiae, or suspicious lesions.
Cardiopulmonary: Regular rate and rhythm with normal S1 and S2 heart sounds; no murmurs, S3, S4, or peripheral edema noted. Lungs are clear to auscultation bilaterally with unlabored respiratory effort.
Abdomen & Musculoskeletal: Gravid abdomen proportional to 20 weeks’ gestational age. Bowel sounds normoactive in all four quadrants; no focal abdominal tenderness. Full range of motion across all major joints without spinal tenderness.
Pelvic & Gynecological: External genitalia normal without lesions or masses. Speculum exam demonstrates a smooth cervix free of discharge, erosions, or lesions. Uterus is anteverted, enlarged to the umbilicus, and non-tender. Rectal tone is normal without hemorrhoids.
Neurological & Psychiatric: Alert and oriented x3. Speech is clear and coherent. Posture and gait are steady. Displayed subtle emotional hesitation when addressing domestic dynamics.

Diagnostic Assessment and Clinical Reasoning

Primary Diagnosis

Second Trimester Pregnancy (13–26 Weeks Gestation) — ICD-10: Z34.82

The clinical evaluation confirms a progressing 20-week intra-uterine pregnancy. Physical symptoms including lumbar strain, mild constipation, urinary frequency, and uterine enlargement align with normal second-trimester physiological adaptations. The patient’s lower back pain stems from lordotic posture shifts, altered center of gravity, and ligamentous relaxation driven by circulating relaxin.

Differential Diagnoses

Spontaneous Abortion / Pregnancy Loss: Although the patient has a history of miscarriages, this diagnosis is excluded at present due to the absence of vaginal bleeding, pelvic cramping, tissue clearance, or cervical dilation.
Gestational Trophoblastic Disease (Molar Pregnancy): Characterized by abnormal placental proliferation, severe hyperemesis, markedly elevated hCG levels, or vaginal bleeding. Excluded based on normal anatomical development at 20 weeks and clear physical exam findings.

Comprehensive Plan of Care

Pharmacological Management and Pain Relief

Medication administration during pregnancy requires weighing maternal therapeutic benefit against potential fetal risk:

Pain Management: Acetaminophen (Tylenol) up to 1,000 mg every 6 hours as needed (not to exceed 3,000 mg/day) for lower back pain. NSAIDs like ibuprofen must be avoided, particularly in the second and third trimesters.
Gastrointestinal Relief: Docusate sodium (Colace) 100 mg orally daily to treat constipation by increasing stool water content. Famotidine (Pepcid) 20 mg as needed for gastroesophageal reflux.
Supplements: Continue daily over-the-counter prenatal vitamins containing at least 400–800 mcg of folic acid and elemental iron.

Non-Pharmacological Interventions and Lifestyle Modifications

Non-pharmacological strategies offer safe relief for musculoskeletal strain:

Perform low-impact exercises such as prenatal swimming, walking, and pelvic tilt exercises to strengthen core and lumbar support muscles.
Practice proper body mechanics: bend at the knees rather than the waist, avoid prolonged standing, and use supportive footwear.
Utilize a supportive pregnancy belly belt and place a body pillow between the knees while side-sleeping to maintain neutral spinal alignment.

Patient Counseling, Safety, and Risk Reduction

Alcohol Cessation Counseling: Provide direct psychoeducation regarding the non-existence of a safe threshold for alcohol consumption during pregnancy. Explain the risks of Fetal Alcohol Spectrum Disorders (FASD) and advise immediate, complete abstinence from all alcoholic beverages.
Latex Allergy Avoidance: Document the latex allergy prominently in the electronic medical record and counsel the patient to inform all care providers to ensure latex-free gloves and equipment are utilized.
Red-Flag Warning Signs: Instruct the patient to seek urgent medical attention if she experiences vaginal bleeding, fluid leakage, severe abdominal or pelvic pain, fever, sudden upper extremity or facial edema, severe headaches, visual disturbances, or a decrease in fetal movement.

Diagnostic Workup and Interprofessional Referrals

Laboratory Screening Panel: Order Complete Blood Count (CBC) to screen for maternal anemia, Blood Type and Rh Factor antibody screen, Hepatitis B Surface Antigen (HBsAg), Syphilis (RPR/VDRL), and Rubella immunity status.
Gestational Diabetes & Diagnostic Imaging: Schedule a 1-hour Oral Glucose Tolerance Test (OGTT) between 24 and 28 weeks’ gestation. Order an anatomical survey ultrasound to evaluate fetal organ development, placental location, and amniotic fluid volume.
Mental Health & Psychosocial Screening: Administer the Patient Health Questionnaire-9 (PHQ-9) and Perinatal Anxiety Screening Scale (PASS) to establish a psychiatric baseline given her past depressive episodes. Conduct a secondary intimate partner violence (IPV) screening due to her non-verbal discomfort during the social history exam.
Referrals & Follow-Up: Refer to an Obstetrics/Gynecology specialist for collaborative prenatal care. Schedule her next routine prenatal follow-up visit in 4 weeks.
