Practice question

Try one before you read

A real case from the bank, in the new short-menu format. Answer it first. Then read the key features.

Key feature 1 · Pregnancy test firstShort menu · Select three

You are working in the emergency department of a regional hospital. A 16-year-old girl is brought in by her mother with crampy lower abdominal pain and vaginal bleeding since this morning, heavier than a period and with clots. Her last period began six weeks ago; her periods usually come every four weeks. Her mother answers most of your questions and says her daughter has never had a boyfriend; the girl looks at the floor. Two days ago she fell onto her left side during a basketball game. She takes no regular medications and has had ibuprofen 400 mg twice today. Her temperature is 37.0 °C, pulse 108/min and blood pressure (BP) 112/70 mm Hg. Her lower abdomen is tender, more on the left.

Which of the following investigations are the most appropriate at this time? Select THREE.

Key feature 1 of 4

Pregnancy test first

Check for pregnancy first in every patient who comes in with bleeding.

CFPC skill Clinical reasoningPhase Hypothesis generation, diagnosisSources Health Canada

On the exam

A 17-year-old with heavy bleeding and cramps, two days after a fall. Expect a short menu (pick several from a list) of first tests.

Pick the first tests.

Common mistakes

An X-ray or CT for pain after the fall before you know if she is pregnant. Or cultures and a clotting screen that do not explain the bleeding.

Approach

  • Test every patient who could be pregnant, from the first period to menopause. Test even when sex is denied.
  • Ask a teen about sex alone, without a parent in the room.
  • Positive test: find out where the pregnancy is.
  • Know the result before any X-ray or CT.
  • Do not start a combined pill until pregnancy is excluded. Canadian product labels list suspected pregnancy and unexplained bleeding as reasons not to.
  • A work-up for a bleeding disorder comes after a negative test, not before it.

Key feature 2 of 4

Bleeding in pregnancy

When a pregnant patient bleeds, find the dangerous cause, give Rh care, and treat shock.

On the exam

Positive test, empty uterus, a mass beside the ovary, then falling pressure. Expect one best answer at each step.

Pick the diagnosis, then the next step.

Common mistakes

Calling it a completed miscarriage, or rescanning once the pressure falls. Then giving Rh immunoglobulin at six weeks, which current Canadian guidance advises against.

Approach

  • Early pregnancy: think ectopic pregnancy and miscarriage. Later on: think placental abruption, the placenta pulling away from the uterine wall.
  • No clear pregnancy in the uterus on ultrasound: keep ectopic in mind. A mass beside the uterus makes an ectopic more likely.
  • Consider a second blood level of the pregnancy hormone, human chorionic gonadotropin (hCG), 48 hours later. It lowers the chance of missing an ectopic.
  • Do not call it a complete miscarriage on an empty uterus alone. Without an earlier scan or lab proof of a pregnancy in the uterus, follow hCG levels.
  • Falling pressure with a likely ectopic: two large intravenous (IV) lines, fluids and blood, a crossmatch (matching donor blood for transfusion), and straight to surgery. No more imaging.
  • Rh D-negative, not already sensitized (no anti-D antibodies in her blood), and bleeding: no Rh immunoglobulin before 8 weeks. From 8 to 12 weeks, usually none. After 12 weeks, the guideline suggests 300 µg.
  • From 20 weeks, after a bleed that may have let fetal blood cross, measure how much fetal blood entered the mother's blood. Use a Kleihauer-Betke test or flow cytometry. The result sets the dose.

Key feature 3 of 4

Not pregnant, bleeding heavily

Not pregnant: find serious causes by age, treat shock, and pick medicine or surgery.

CFPC skill Clinical reasoning, selectivityPhase Investigation, diagnosis, treatmentSources Society of Obstetricians and Gynaecologists of Canada, Choosing Wisely Canada, Health Canada

On the exam

A 15-year-old with heavy periods since her first one, nosebleeds and migraine with aura. Expect a short menu (pick several from a list), then one best answer.

Pick the work-up, then the treatment.

Common mistakes

Missing the bleeding-disorder clues at 15. Then a combined pill despite her aura, even a low-dose one, or ablation in a teen.

Approach

  • Ask for clues to a bleeding disorder: heavy periods since the first one, nosebleeds, easy bruising, bleeding after dental work, and family history.
  • Von Willebrand disease is the commonest inherited bleeding disorder. Its factor tests are usually done in specialised centres.
  • Pick tests by age. In a teen with heavy periods since the first one, check for a bleeding disorder. In older patients, weigh structural causes and cancer.
  • No Pap test at 15. It screens for cervical cancer; it does not explain heavy periods.
  • Unstable: fluids, blood and urgent gynecology come before any office work-up.
  • Stable but heavy: medical treatment first, such as a levonorgestrel intrauterine device (IUD) or tranexamic acid. Endometrial ablation (surgery that destroys the uterine lining) comes only if medical options fail or are declined.
  • Migraine with aura rules out combined pills. Canadian product labels list it as a contraindication.

Key feature 4 of 4

After menopause

Work up bleeding after menopause soon, with an exam, ultrasound and tissue sampling.

CFPC skill Clinical reasoningPhase InvestigationSources Choosing Wisely Canada

On the exam

A 62-year-old woman spots for the first time in nine years. Expect a short menu (pick several from a list) of first steps.

Pick the first steps.

Common mistakes

Calling it atrophy (a thin, dry vaginal lining) and giving vaginal estrogen with no work-up. Or a Pap test alone: it checks the cervix and misses the uterine lining.

Approach

  • See any bleeding after menopause soon. Do not wait for the next routine visit.
  • Ask about risk: obesity, diabetes, never having been pregnant, tamoxifen, and estrogen taken without a progestin.
  • Examine the vulva, vagina and cervix with a speculum, then do a bimanual exam (two fingers in the vagina, the other hand on the belly). Blood can also come from the bladder or bowel.
  • Book the work-up soon, or refer to gynecology if you cannot do it.
  • Do a Pap test only if screening is due. It checks the cervix, not the lining.
  • Bleeding that keeps coming back after normal tests still goes to gynecology.

Flashcards

Answer it first, then check.

  1. KF 1Heavy bleeding and cramps in a teen who says she has never had sex. First test?

    A pregnancy test. Her history cannot exclude pregnancy, and the result decides every next step.

  2. KF 2Rh D-negative and miscarrying at 6 weeks. Does she need Rh immunoglobulin?

    No. Canadian guidance since 2024 advises against it for any pregnancy loss before 8 weeks. Source: Society of Obstetricians and Gynaecologists of Canada

  3. KF 2Rh D-negative with a threatened miscarriage at 14 weeks. What dose?

    300 µg of Rh immunoglobulin. After 12 weeks, the 2024 guideline suggests giving it. Source: Society of Obstetricians and Gynaecologists of Canada

  4. KF 2Positive test, empty uterus, a mass beside the ovary, pressure 80/50. Next step?

    Resuscitate and go to the operating room now. Do not send her for more imaging.

  5. KF 3Heavy periods since the first one, nosebleeds, and oozing after a tooth was pulled. Likeliest cause?

    Von Willebrand disease, the commonest inherited bleeding disorder. Heavy periods are its most common sign in women. Source: Society of Obstetricians and Gynaecologists of Canada

  6. KF 3Heavy periods and migraine with aura. Can she take a combined pill?

    No. Aura is a contraindication. Offer a levonorgestrel IUD or tranexamic acid instead. Source: Health Canada, Choosing Wisely Canada, Society of Obstetricians and Gynaecologists of Canada

  7. KF 4A 64-year-old has spotted twice. Her Pap last year was normal. Is that enough?

    No. A Pap checks the cervix, not the uterine lining. Bleeding after menopause needs its own work-up soon.

FAQ

Does the exam still expect Rh immunoglobulin for every early bleed?

The CFPC names no guideline. Answer with the SOGC's 2024 guideline: none before 8 weeks, usually none from 8 to 12 weeks, and 300 µg suggested after 12.

Does every pregnant patient who bleeds need a blood type?

Not for Rh before 8 weeks: the 2024 guideline drops routine typing that early. After 8 weeks, type and screen. A patient bleeding heavily still needs a crossmatch for transfusion.

Is a lower-dose combined pill safe with migraine with aura?

No. The Canadian product monograph for a common low-dose combined pill lists migraine with aura as a contraindication, with no dose exception. Pick a levonorgestrel IUD or a non-hormonal option instead.

Is Rh immunoglobulin dosed in micrograms or units?

Either. In Canada, 120 µg is 600 IU and 300 µg is 1,500 IU. The vials come in 120, 300 and 1,000 µg. This page uses micrograms.
