The Gynecologic Patient and Menstruation

  • Menstruation Overview:
    • A normal physiological cycle involving preparation for conception.
    • Menarche: The onset of the first menstrual period.
    • Cycle Characteristics: Typically occurs monthly, lasting between 33 to 77 days, driven by hormonal changes.
  • Menopause:
    • The permanent cessation of the menstrual cycle.
    • Natural Menopause: Typically occurring between the ages of 4545 and 5555.
    • Surgical Menopause: Occurs when the ovaries are removed surgically.
    • Stages: Includes premenopause and perimenopause.

The Gynecologic Examination

  • Purpose of the Exam:
    • To provide an overview of a woman's general health.
    • To perform cancer-screening exams and tests.
  • Personnel Requirements:
    • A female medical assistant should be present during the exam for two primary reasons:
      • To assist the physician.
      • To provide legal protection for the practitioner and the patient.
  • Roles of the Medical Assistant:
    • Instruct the patient to empty their bladder before the exam.
    • Provide the patient with a gown and drape.
    • Conduct the patient interview and check vital signs.
    • Observe the patient for any signs of physical or emotional problems.
    • Determine the first day of the Last Menstrual Period (LMP).
    • Assist the patient into the correct position (usually lithotomy for pelvic exams).
    • Prepare instruments and testing materials.
    • Provide patient teaching.
  • The Physician’s Interview:
    • Focuses on the evaluation of total health.
    • Involves reviewing factors indicative of cancer or sexually transmitted infections (STIs).

Components of the Gynecologic Exam

  • Breast Exam:
    • Includes checking for abnormal lumps.
    • Detection Guidelines: Annual breast exams are recommended; the patient should know the normal appearance and feel of her breasts. Mammograms are used for screening. Patients with a significant family history may require an MRI.
  • Pelvic Exam:
    • Inspection: Examination of the external genitalia, as well as the vagina and cervix using a speculum.
    • Palpation (Bimanual Exam): The practitioner uses two hands to examine the vagina and abdomen, and the rectum and abdomen.
  • Common Diagnostic Tests During Pelvic Exam:
    • Pap smear: To screen for abnormal or precancerous cells.
    • KOH (Potassium Hydroxide): Used to identify fungal elements.
    • Wet mount: Used to view moving microorganisms like Trichomonas or bacteria under a microscope.

Obstetrical Care and Prenatal Health

  • Estimating Delivery Dates (Nägele’s Rule):
    • The Estimated Date of Delivery (EDD) is calculated by taking the first day of the last period, subtracting 33 months, adding 77 days, and adding 11 year.
    • Example: If LMP is January 23, the calculation is:
    • 1.\n\text{January } 23 - 3\,\text{months} = \text{October } 23
    • 2.\n\text{October } 23 + 7\,\text{days} = \text{October } 30
    • 3.\n\text{Add } 1\,\text{year} \rightarrow \text{October } 30\text{th (EDD)}
  • Prenatal Care Guidelines:
    • Nutrition: Eat well and exercise.
    • Attendance: Keep all medical appointments and attend childbirth classes.
    • Avoidance: Strictly avoid tobacco, alcohol, and drugs.
  • Normal Changes During Pregnancy:
    • Morning sickness.
    • Weight gain.
    • Urinary frequency.
    • Depression.
    • Constipation.
    • Swelling of the hands and feet.
  • Monitoring by Licensed Practitioners:
    • Tracks blood pressure, weight gain, and checks urine for the presence of protein.
    • Prescribes prenatal vitamins and iron.
    • Monitors for complications such as Placenta Previa, Abruptio Placenta, and Gestational Diabetes.

Labor, Delivery, and Postpartum Care

  • Labor Instructions:
    • Patients are told to go to the hospital if they experience regular contractions defined as 66 or more per hour for at least 22 hours.
    • If their "water breaks," this is a sign of impending labor.
  • Delivery Types:
    • Natural Delivery: Following spontaneous onset or induction.
    • Cesarean Section (C-Section): Surgical delivery.
  • The Delivery Process: Clamping, tying, and cutting the umbilical cord; presenting the infant to the mother.
  • Postpartum Period:
    • The body returns to its normal state.
    • Involves the uterus shrinking, potential difficulty with urination and bowel movements, postpartum bleeding, and emotional stress.
  • Infant Feeding Options:
    • Breastfeeding: Colostrum provides immunity; it is economical and convenient.
    • Bottle Feeding: An acceptable alternative using formula. Patient instructions should include formula type and preparation. Cow’s milk should be avoided for infants.

OB/GYN Diagnostic and Therapeutic Procedures

  • Pregnancy Tests: Detect the presence of HCG (Human Chorionic Gonadotropin) in blood or the first voided urine.
  • STI Testing: Involves bacterial and tissue cultures, examining lesions, blood tests, and detailed patient history. Reporting to the state is often required, and written consent is needed to release results.
  • Radiologic Tests:
    • X-rays should generally be avoided if the patient is pregnant.
    • Other tools include Ultrasonography, CT scan, and MRI.
    • Hysterosalpingography: Imaging of the uterus and fallopian tubes.
    • Mammogram: Specialized X-ray for breast tissue.
  • Fetal Screening:
    • Alpha fetoprotein (AFP): Abnormal levels may indicate neural tube defects.
    • Ultrasound: Used to identify cysts, tumors, or obstructions, and to determine fetal size, position, and number of fetuses. It is also used as a guide for invasive procedures.
  • Invasive Procedures:
    • Amniocentesis: Sampling amniotic fluid to check for genetic or metabolic problems.
    • Chorionic Villus Sampling (CVS): Sampling placental tissue to check for genetic disorders.
    • Colposcopy: Examination of the vagina and cervix to identify abnormal cells.
    • D and C (Dilation and Curettage): Dilation of the cervix and scraping of the uterine lining.
    • LEEP (Loop Electrosurgical Excision Procedure): Removal of abnormal cervical tissue using a wire loop; often done during colposcopy.
    • Cryosurgery: Freezing and destroying abnormal tissue.
    • Stereotactic Core Biopsy: Using three-dimensional coordinates to obtain a tissue sample from the breast.
  • Hysterectomy Types:
    • Hysterectomy: Surgical removal of the uterus.
    • Hysterosalpingectomy: Removal of the uterus and fallopian tubes.
    • Hysterosalpingo-oophorectomy: Removal of the uterus, fallopian tubes, and ovaries.
