Question

social hx: 1-pack-per-day smoker, social drinker: 3-4 glasses of wine a week. family hx: positive for psoriasis in mother. pmhx: dermatofibromas × 3 on legs removed via cryosurgery 3 years ago. which of the following is true about this patient’s medical history? 1) her fatty tumors were removed by using electricity to destroy them. 2) her fibrous skin tumors were removed by freezing. 3) her hernias filled with fatty tissue were cut and drained. 4) her horny tissue condition was removed with chemicals. 5) her yellow tumors were rubbed or scraped away.

Explanation:

1. Analyze option 1: The patient had dermatofibromas (fibrous skin tumors, not fatty tumors) removed via cryosurgery (not electricity). So option 1 is wrong.
2. Analyze option 2: The PMHx says dermatofibromas (fibrous skin tumors) were removed via cryosurgery (which involves freezing). This matches.
3. Analyze option 3: The patient's history is about dermatofibromas, not hernias. So option 3 is wrong.
4. Analyze option 4: Cryosurgery uses freezing, not chemicals, and dermatofibromas are not "horny tissue condition". So option 4 is wrong.
5. Analyze option 5: The removal was via cryosurgery (freezing), not rubbing/scraping. And dermatofibromas are not "yellow tumors". So option 5 is wrong.

Answer:

1. Her fibrous skin tumors were removed by freezing.
