She says that her last menstrual period was 7 weeks ago, which is unusual because her menstrual period "always" occurs every 29 days.

She is married, does not have any children, and has never been pregnant. Physical examination shows a tender left-sided adnexal mass and blood at the cervix. An ultrasound shows a left-sided adnexal mass. Beta-human chorionic gonadotropin levels are positive, but low for gestational age. Her blood type is O, Rh-negative.

There is an extension of similar lesions to her upper medial thighs. No pustules, bullae, or burrows are appreciated. The remainder of the physical examination is unremarkable. A biochemical profile is normal. She should be told that she has A. a form of pustular psoriasis and should be started on systemic corticosteroid B. Herpes gestationis and will most likely develop similar lesions in subsequent pregnancies C. prurigo gravidarum and will be at increased risk for postpartum hemorrhage D. pruritic urticarial papules and plaques of pregnancy and it typically will resolve postpartum without treatment E. scabies and needs to be treated with permethrin 23) A 17-year-old runaway comes to the emergency department because of a 24-hour history of lower abdominal pain and vomiting.

He had 6 wet diapers the previous day. Examination shows an active infant with a temperature of 38.8 C (101.8 F).

The parents describe the emesis as "forceful", non-bloody, and non-bilious. The baby is exclusively breastfed and continues to be hungry after each episode of vomiting. They deny any fevers. You notice an active baby boy with unremarkable vital signs. Physical examination is significant for a peristaltic wave on the abdomen and a 2x2 cm firm mass palpated in the midepigastric region. Laboratory studies show a bicarbonate level of 18 mEq/L. The most likely diagnosis is A. annular pancreas B. gastroesophageal reflux C. intussusception D. malrotation with volvulus E. pyloric stenosis 7
