Which option is appropriate when a patient is NPO: hold prandial insulin or hold basal insulin?
Which option is appropriate when a patient is NPO: hold prandial insulin or hold basal insulin?
Tap to reveal answer
Hold prandial insulin; usually continue basal per order. Prandial covers meals, so hold when NPO; basal maintains fasting control and prevents ketosis.

Which insulin type provides basal coverage with minimal or no peak (examples: glargine, detemir, degludec)?
Which insulin type provides basal coverage with minimal or no peak (examples: glargine, detemir, degludec)?
Tap to reveal answer
Long-acting insulin (basal, minimal peak). Maintains steady basal insulin levels without significant peaks to mimic natural background insulin secretion.
