Answer to Question 1

C
Feedback:
Hypomagnesemia increases myocardial irritability. Magnesium deficit prolongs the QRS complex instead of decreasing the QRS complex. Hypomagnesemia does not increase stroke volume. Hypomagnesemia will depress the ST segment, not elevate the ST segment.

Answer to Question 2

B
Feedback:
Hepatotoxicity and peripheral neuropathy are important adverse effects of isoniazid and rifampin. The ALT/AST will assess liver function. The hematocrit and hemoglobin are not indicated with the described symptoms. Erythrocyte count and differential are not indicated with these symptoms.
