Patient encounter

Patient instructions

  • When the examinee asks you where the pain is located, point at the right lower part of your abdomen.
  • When the examinee presses on the right lower part of your abdomen, say that it hurts.
  • You are not aware of the meanings of medical terms (e.g., ultrasound) and ask for clarification if the examinee uses them.
  • Use the checklists below for history, physical examination, and communication and interpersonal skills.

Challenge: After the examinee explains to you what she/he thinks your diagnosis might be, ask “Does this mean I am going to need surgery?”

Focused history

Hovering over or clicking on the speech bubbles in the lists below will reveal extra information about the adjacent term. However, clicking on links will cause you to navigate away from the current case, at which point your progress (i.e., your check marks) will be lost. If you do want more information on a subject, either open the link in a new tab or wait until you and your partner have finished the case and reviewed the check marks. Following the link to the patient note form or the abbreviation list will not interrupt your progress.

Focused physical examination

Since a pelvic examination is one of the “banned” examinations of Step 2 CS, an abdominal examination should be performed instead on all patients with pelvic pain, and pelvic examination should be ordered as one of the diagnostic studies.

Communication and interpersonal skills

Patient interaction

  • Examinee knocked on the door.
  • Examinee introduced him- or herself and identified his/her role.
  • Examinee correctly used the patient's name.
  • Examinee asked open-ended questions.
  • Examinee listened attentively (did not interrupt the patient).
  • Examinee showed interest in the patient as a person (i.e., appeared caring and showed respect).
  • Examinee demonstrated the ability to support the patient's emotions (i.e., offered words of support, asked for clarification).
  • Examinee did not repeat painful maneuvers during physical examination.
  • Examinee discussed initial diagnostic impressions with the patient.
  • Examinee explained the management plan.
  • Examinee used non-medical terms and provided reasons for planned steps in management.
  • Examinee evaluated the patient's agreement with the next diagnostic steps.
  • Examinee asked about concerns or questions.

Counseling and challenge

Suggested response to challenge: “Ms. Hernandez, I understand your concern that you will have to undergo surgery. Right now, it is not possible for me to say what exactly is causing your pain. In order to do that, I will have to run some tests and do a pelvic examination, as well as do some imaging of your abdomen. Then you and I can discuss the results and the possible treatment options together. Does that sound okay? I promise you I will be with you every step of the way.”

Further discussion

Patient note

Differential diagnoses

  1. Ovarian cancer: Although they are unspecific symptoms, dull lower abdominal pain, increased urinary frequency, decreased appetite, and changes in the menstrual cycle (spotting) can all be signs of ovarian cancer and warrant further evaluation. Additionally, an increase in abdominal girth is often the first sign of ovarian cancer and early menarche and nulliparity are risk factors. Although ovarian cancer is rare in young women, this patient's family history is concerning for a BRCA mutation which would significantly increase her risk for both ovarian and breast cancer, making this the first differential diagnosis that should be considered.
  2. Ectopic pregnancy: Possible amenorrhea, an increase in abdominal girth, increased urinary frequency, and nausea in a patient that uses the calendar method for contraception all suggest pregnancy. The dull lower abdominal pain followed by sudden-onset sharp pain and the tenderness to palpation in the right lower quadrant make an ectopic pregnancy likely. While this diagnosis needs to be ruled out, possible ovarian cancer should be investigated first because of the patient's family history.
  3. Ruptured ovarian cyst: Sudden-onset sharp lower abdominal pain that starts during or following exercise is often caused by a ruptured ovarian cyst. The condition is particularly common in patients between 18–35 years of age, such as this woman. However, an ovarian cyst would not explain this patient's history of dull abdominal pain for 3 weeks or her other symptoms (nausea, increased urinary frequency, etc.), which is why it is listed as the third differential diagnosis here.
