Which rapid-acting insulin has a peak time of 1-1.5 hours? a) Glargine b) Lispro Correct: b) Lispro Rationale: Lispro is a rapid-acting insulin with peak time of 1-1.5 hours and duration of 3-4 hours, used for meal coverage and correction of high blood glucose. What is the primary concern when giving metformin to a patient receiving contrast dye? a) B12 deficiency b) Lactic acidosis Correct: b) Lactic acidosis Rationale: Contrast can cause nephropathy, reducing renal function. Since metformin is excreted by kidneys, reduced function can lead to metformin buildup and potentially fatal lactic acidosis. Which mnemonic helps remember rapid-acting insulins? a) \"Regular and Short\" b) \"Do not LAG\" Correct: b) \"Do not LAG\" Rationale: LAG stands for Lispro, Aspart, and Glulisine - the three rapid-acting insulins. How long do long-acting insulins typically last? a) 16 hours b) 24 hours Correct: b) 24 hours Rationale: Long-acting insulins (Glargine, Detemir) last 24 hours and provide basal insulin replacement without peak times. Which adverse effect is associated with SGLT2 inhibitors? a) Pancreatitis b) Urinary tract infections Correct: b) Urinary tract infections Rationale: SGLT2 inhibitors cause glucosuria, increasing risk of UTIs and vaginal yeast infections. 6. What is the duration of action for NPH insulin? a) 4-6 hours b) 10-16 hours Correct: b) 10-16 hours Rationale: NPH is an intermediate-acting insulin with peak at 8 hours and duration of 10-16 hours.
