Question 1 of 5
Adverse effects of metformin include all of the following EXCEPT:
Correct Answer: B
Rationale: Metformin's adverse effects include lactic acidosis (choice A), a rare but serious risk due to lactate accumulation, especially in renal impairment; nausea (choice C), a common GI upset; and vitamin B12 interference (choice D), from altered absorption. Hypoglycemia (choice B) is not typical, as Metformin reduces hepatic glucose output and enhances insulin sensitivity without directly stimulating insulin release, unlike sulfonylureas. This exception underscores Metformin's safety profile in type 2 diabetes, avoiding the hypoglycemic risk of secretagogues. Understanding this is vital for prescribing, monitoring renal function to prevent lactic acidosis, and addressing B12 deficiency in long-term users.

Question 5 of 5
When initiating T4 therapy for an elderly patient with long-standing hypothyroidism, it is important to begin with small doses to avoid:
Correct Answer: D
Rationale: In elderly hypothyroid patients, small T4 doses (choice D) prevent cardiac overstimulation (e.g., tachycardia, angina) due to increased sensitivity and comorbidities. Exophthalmos (choice A) is hyperthyroid, renal failure (choice B) and hemolysis (choice C) aren't typical risks. Cardiac caution is key.
