1. drug binds to both glucocortoid and mineralocortoid receptors
2. drug is converted to a mineralocortoid in the liver
3. pulmonary production oif angiotensin is increased
4. renin activity is increased b'cos of stress
5. secretion of ADH(vasopressin) in increased because of stress
II. 62 yr old man develops numerous superficail blister over the scalp, face, groin, trunk. New lesions develop over areas subjected to minimal trauma. Biopsy of one of the lesions shows an intraepidermal blister with suprabasal acantholysis. Serologic studeies are likely to show an autoantibody directed against which of the following?
1. anchoring filaments
2. basement membrane protiens
3. desmosomal proteins
4. hemidesmosomal proteins
5. integrins
III. which of the following drugs produces vasoconstriction that is not blcoked by prazosin and bradycardia that is blocked by scopolamine?
1. amphetamine
2. angiotensin
3. norepinephrine
4. phenylephrine
IV. 3 wk old female infant with dehydration develops bilateral renal vein thrombosis, but only the right kidney infarcts. Collateral drainage vioa which of the follwoing veins most likely prevented infarction of the left kidnet
1. left ovarian
2. left third lumbar
3. splenic
4. superior mesenteric
