The decision may be made to switch from twice daily neutral protamine Hagedorn (NPH) insulin to insulin glargine to improve glycemia control throughout the day. If this is done:
- A. The initial dose of glargine is reduced by 20% to avoid hypoglycemia

- C. Patients who have been on high doses of NPH will need tests for insulin antibodies
- D. Obese patients may require more than 100 units per day
Correct Answer: A
Rationale: Switching to glargine reduces the dose by 20% to prevent hypoglycemia due to its steady action vs. NPH peaks.

Acetyl salicylate & phenobarbitone are better absorbed from stomach because they are
- A. Weak acids remain non-ionic in gastric pH
- B. Weak acids remain ionic in gastric pH
- C. Strong acids fully ionized in gastric pH
- D. Weak bases which are ionized at gastric pH
Correct Answer: A
Rationale: Weak acids like acetyl salicylate (aspirin) and phenobarbitone remain non-ionic in the acidic pH of the stomach, facilitating their absorption through passive diffusion across the gastric mucosa.
Inhibition of P-glycoprotein by a drug such as quinidine may lead to:
- A. Decreased therapeutic levels of quinidine
- B. Increased therapeutic levels of quinidine
- C. Decreased levels of a coadministered drug, such as digoxin, that requires P-glycoprotein for absorption and elimination
- D. Increased levels of a coadministered drug, such as digoxin, that requires P-glycoprotein for absorption and elimination
Correct Answer: D
Rationale: Quinidine inhibits P-glycoprotein, increasing levels of drugs like digoxin by reducing efflux, not affecting quinidine itself or lowering digoxin .
