Diltiazem is a nondihydropyridine calcium channel blocker that prolongs survival in patients with pulmonary hypertension. Diltiazem does not bind endothelin receptors. +
Flumazenil is a benzodiazepine receptor antagonist used to treat benzodiazepine overdose. +
The intercostal space contains the intercostal Vein, Artery, and Nerve (VAN) in that order from superior to inferior. +
Farnesyl groups can be added to proteins for their proper localization to cell membranes. Farnesylation does not target proteins for degradation. +
GLUT2 is a bidirectional glucose transporter that is expressed in pancreatic islet cells, the liver and the kidney. It does not translocate to the cell membrane with exercise. +
The lateral pterygoid is the only muscle of mastication with two heads, and the only muscle responsible for opening the jaw. +
From below the pectinate line, the rectum is drained by the superficial inguinal lymph node. +
The mesenteric lymph nodes drain the gut. The superior mesenteric lymph nodes drain all parts of the gut proximal to the sigmoid colon. The inferior mesenteric lymph nodes drain lymph from the sigmoid colon to the rectum (above the pectinate line). +
This is the mechanism of action of ondansetron, an anti-emetic used in conjunction with chemotherapy. Ondansetron is not effective in treating migraine headaches. +
Patients with normal renal and cardiac function do not require diuretics necessarily; however, furosemide use is preferred in TLS patients because it causes further renal secretion of potassium after filtration. +

While ''S. aureus'' is a catalase-positive, gram-positive coccus, it is coagulase-positive. +
Propylthiouracil (PTU) is an anti-thyroid drug that inhibits thyroperoxidase, an enzyme essential for the synthesis of T4. It also inhibits the conversion of T4 to T3 peripherally. Because De Quervain’s thyroiditis eventually causes hypothyroidism, an anti-thyroid drug is not recommended. +
The patient in this vignette most likely has a spontaneous pneumothorax, which are thought to arise from the rupture of apical blebs (small air-filled lesions under the pleural surface). +
''' Incorrect ''' : X-linked inheritance of a single parent will result in 50 percent of her sons to be affected and 50 percent her daughters to be carriers. +
''' Incorrect ''' : The appearance of otherwise unexplained thrombocytopenia, thrombosis associated with thrombocytopenia, a platelet count which has fallen 50 percent or more from a prior value, or necrotic skin lesions at heparin injection sites should raise the possibility of heparin-induced thrombocytopenia (HIT) in any patient begun on heparin therapy within the preceding 5 to 10 days. +
''' Incorrect ''' : The platelet count can be temporarily supported by the use of intravenous immune globulin (IVIG) or by anti-Rh(D) (Rho(D) immune globulin, anti-D, WinRho) in patients whose red cells are Rh(D) positive and who have not had a splenectomy. Both of these agents increase the platelet count in most patients with ITP, including patients who have not responded to corticosteroids, within several days, with an effect that may last for several weeks +
