Answer is wrong

Posted by Thomas Lawton, 7 Dec 2025, 0 comments

Answer is wrong

Karyotyping the mother is NOT the correct tool for estimating the risk of Down syndrome in her fetus.

The mother is phenotypically normal, so she cannot have full trisomy 21 herself.

The only scenario where the mother's karyotype matters is if she carries a balanced Robertsonian translocation involving chromosome 21 — but this is rare, and the question gives no suggestion of such.

The given answer confuses:

  • maternal meiotic nondisjunction risk (age-related, statistical)
  • vs.
  • heritable translocation Down syndrome (very rare)

Wrong answer right explanation

The glucose reabsorption in the PCT in the kidneys of a Type 2 DM patient is not decreased, just simply maxed out, and SGLT2 cannot accomodate all the glucose, so it goes through into the urine. The answer implies reabsorption is decreased when it isn't.

Review of Question Vignette or Answer Choices

Review of Question Vignette or Answer Choices

While ETEC is known to be the primary cause of Traveler's diarrhea based on its watery characteristic, its heat-labile/stable enterotoxins do not cause inflammation or invasion. On the other hand, EIEC's microbes invade the intestinal mucosa, causing necrosis and inflammation similar to that of Shigella, which leads to watery diarrhea progressing to blood and mucus in the stool. Therefore, I think this question needs to be reviewed to reform the stem to point towards ETEC or change the answer choices.

Beta-3 adrenergic agonists, like mirabegron and vibegron, are indicated in overactive bladder (OAB) in adults, not beta-2 agonists.
