Which is NOT an advantage of dalteparin over unfractionated heparin?

Correct Answer: D

Rationale: Dalteparin (a low-molecular-weight heparin) has greater bioavailability, less thrombocytopenia risk, and a longer half-life than unfractionated heparin, but greater efficacy is not a consistent advantage, as it depends on the condition treated.

Correct Answer: C

Rationale: Rivaroxaban and dabigatran have rapid onset/offset, no INR monitoring, and fewer CYP450 interactions, but both require dose adjustments in renal failure due to renal clearance, unlike warfarin.

Correct Answer: C

Rationale: Argatroban is IV, used in HIT, and not reversed by protamine, but it’s monitored by aPTT, not INR (which is for warfarin).

Correct Answer: D

Rationale: Alendronate (bisphosphonate) and prednisone (glucocorticoid) reduce GI calcium absorption; raloxifene doesn’t, and alfacalcidiol (vitamin D) enhances it.

Correct Answer: D

Rationale: Bromocriptine (D2 agonist) treats acromegaly (reduces GH) and Parkinsonism (mimics dopamine). L-dopa also treats Parkinsonism. Octreotide is for acromegaly only.
