OB/GYN Procedures

Foundations of OB/GYN Procedure Assistance

OB/GYN (Obstetrics and Gynecology) procedures are a core component of medical assisting in women's health. Medical assistants (MAs) are often responsible for preparing patients, assisting the provider, collecting specimens, and documenting findings. Understanding these procedures ensures safe, efficient, and compassionate care. High-yield exam concepts include patient education, sterile technique, speculum use, Pap smear technique, and infection control standards.^[1]

Essential Terminology for Women's Health Procedures

• Speculum examination → A device used to visualize the cervix and vaginal walls.
• Pap smear (Papanicolaou test) → Screening for cervical cancer by collecting cells from the cervix.^[2]
• Bimanual examination → Provider palpates the uterus and adnexa using two hands.
• Colposcopy → Magnified examination of the cervix after application of acetic acid.
• Endometrial biopsy → Sampling of endometrial lining for pathologic evaluation.
• Fetal monitoring → Assessment of fetal heart rate and uterine contractions during pregnancy.

Routine OB/GYN Exam Sequence

1. Preparation for Gynecologic Examination

1. Verify patient identity and obtain verbal consent.
2. Instruct patient to empty bladder (a full bladder can cause discomfort and obscure findings).^[3]
3. Provide a drape and instruct patient to undress from waist down.
4. Assist patient into lithotomy position (feet in stirrups, buttocks at edge of table).
5. Ensure adequate lighting and have necessary supplies ready (speculum, lubricant, cytobrush, spatula, fixative).
6. Remain present to offer reassurance and assist the provider as needed.

2. Pap Smear Technique

• The provider inserts a speculum to expose the cervix.
• Ectocervical sample: A spatula is rotated 360° around the external os.
• Endocervical sample: A cytobrush is inserted into the cervical os and rotated.
• Both samples are immediately transferred to a slide or liquid-based medium (per lab protocol).
• Fixative is applied immediately for conventional smears to avoid air-drying artifact.^[2]
• Label slide with patient name, date of birth, and date of collection.

3. Specimen Collection and Handling

• Use preservative fluids (e.g., SurePath, ThinPrep) for liquid-based cytology.
• Transport specimens at room temperature; do not freeze.
• Ensure requisition form includes: patient demographics, last menstrual period, hormonal therapy, and prior abnormal results.
• Chain of custody is required for forensic evidence collection (sexual assault cases).

Pre-Procedure Patient Guidance

• Advise patient to avoid douching, intercourse, or vaginal medications 24–48 hours before exam.^[4]
• Explain that the procedure may cause mild discomfort but is brief.
• For pregnant patients, speculum exams may be performed to assess cervical dilation or obtain cultures (GBS screening at 36–37 weeks).
• Teach patient to report excessive bleeding, pain, or fever after procedures.

Clinical Assessment of Gynecologic Findings

• Normal findings: Cervix pink, smooth, with clear or white mucus; no lesions or friability.
• Abnormal findings: Friability, abnormal discharge, visible lesions (may require colposcopy).
• Pap results are reported using Bethesda System (e.g., ASC-US, LSIL, HSIL).^[2]
• HPV co-testing is often performed for women ≥30 years with Pap.

Adverse Event Prevention and Infection Control Measures

• Always use standard precautions (gloves, gown, eye protection).
• Speculum should be warmed with water (not lubricant) if collection for cytology is planned (lubricant can interfere with cell adhesion).
• Avoid trauma: never force speculum closure on the cervix.
• Monitor for vasovagal response (fainting, bradycardia, nausea) during speculum insertion; have patient cough or take deep breaths.^[3]
• Post-procedure bleeding: normally scant; report heavy bleeding.
• Infection control: disinfect specula and surfaces per CDC guidelines.^[5]

Practical Notes and Memorization Tools for Testing

• Remember the order of the gynecologic examination: external inspection, speculum insertion, specimen collection, bimanual exam, rectovaginal exam (if indicated).
• Pap smear is not performed during menstruation; best timing is mid-cycle (day 14–16).
• Memory aid for Pap sampling: "Spatula for outside (ectocervix), brush for inside (endocervix)."
• Liquid-based cytology reduces obscuring blood and mucus, improving sensitivity.
• Know that the Bethesda System is the standard reporting format for cervical cytology – you may see "ASC-US" as a commonly tested term.^[2]
• For pregnant patients: GBS swab is collected from the lower vagina and rectum (not cervix) at 36–37 weeks.
• MA role includes documenting procedure, patient tolerance, and sample labeling.
