Correct Answer - B Ans: B. serum lithium Because of its effects on multiple body systems, including but not limited to renal, hematologic, and thyroid systems, appropriate baseline studies must precede the start of lithium therapy. The minimal tests to be done include serum creatinine, electrolytes, thyroid function tests, and a complete blood count with differential. Additionally, because of its cardiac effect, an ECG is indicated. Any woman thought to be pregnant should have a pregnancy test.

Correct Answer - B Ans: B. PML-RARA All-trans retinoic acid (ATRA) is an active metabolite of vitamin A under the family retinoid. Retinoids, through their cognate nuclear receptors, exert potent effects on cell growth, differentiation and apoptosis, and have significant promise for cancer therapy and chemoprevention. Differentiation therapy with ATRA has marked a major advance and become the first choice drug in the treatment of acute promyelocytic leukemia (APL). All-trans retinoic Acid is used in the treatment for Acute Promyelocytic Leukemia (PML)

Correct Answer - C Ans: C. Metabolic acidosis The given values have low pH, and low HCo3 Indicate metabolic acidosis PCO2 in lower normal range (normal value 35-45 mm/hg)

Correct Answer - A Ans: A. Alcohol An indicator that should make the clinician highly suspicious of alcohol-related liver injury is AST: ALT ratio of 2:1 or more. Gamma-glutamyl transferase (GGT) is another sensitive but non- specific marker for the hepatic injury which cannot be used solely to diagnose alcohol-related hepatic insult. Levels of GGT greater than twice the normal values in addition to AST:ALT ratio >2 strongly indicate alcohol-induced liver injury as well.
