A- Fibrinous pericarditis
B- Hemorrhagic pericarditis
C- Serous pericarditis
D- Suppurative pericarditis
C-Serous pericarditis- Myocardial infarction can lead to inflammation of the pericardium, and serous pericarditis is characterized by an accumulation of serous fluid in the pericardial sac. Fibrinous pericarditis and hemorrhagic pericarditis can also occur but are less common. Suppurative pericarditis is characterized by a purulent or pus-like exudate. It is rare and typically associated with bacterial infections.
Q- Which of the following conditions is characterized by hypertension due to sodium retention, hypokalemia and decreased renin secretion?
A- Conn syndrome
B- Cushing syndrome
C- Diabetes insipidus
D- Renal ischemia
A- Conn syndrome- It is a primary aldosteronism leads to increased sodium and water retention resulting in hypertension. Hypertension is causing decreased renin secretion due to its negative feedback. Renal ischemia is causing increased renin secretion, not decreased.
Q- Which one of the following skin pathological conditions is caused by autoantibodies that react with desmosomes or hemidesmosomes leading to disrupting intracellular junctions?
A- Acne vulgaris
B- Bullous pemphigoid
C- Dermatitis herpetiformis
