What is the route of insulin administration using insulin pump? - SC
What insulin is used in insulin pump? - short acting regular insulin LIN-R - rapid acting insulin Log
which pt population are good candidate for the use of insulin pump? - type -1 - NOT appropriate for newly diagnosed pt
What is the recommended initial insulin dose for type-1 vs. Type-2? - type 1: 0.6 units/kg/day using actual body wt - type II: 0.1-0.2 units/kg/day using actual body wt ( OR 10 units/day )
what are the two insulin dosing strategies ? - basal/ bolus strategy: 50% TDD basal long acting ( once at bed time) and 50% TDD bolus rapid ( the bolus is further divided into 3 x/day) - NPH/ regular strategy:2/3 NPH intermediate and 1/3 NPH short regular ( 2x/day together prior to meal)
Which insulin dose is usually adjusted based on the patient sensitivity and needs? - mealtime ( bolus) - ICR: insulin to carb ratio allows bolus adjustment - ICR: is used to determine the # grams of carbs covered by the patient bolus
what is the rule of 500 in ICR? - rapid acting: 500/TDD= grams of carbs covered by 1 units
what is the rule of 450 in ICR" - short regular acting 450/TDD = grams of carbs covered by 1 unit
example of 500-ICR and 450-ICR? - e.g: TDD is 60 u, insulin used: Novolog ( rapid acting) , 500-ICR = 500/60 - 500-ICR: 500/60= 8 gr carbs IF NovoLIN-R ( regular short): 450-ICR = 450/60= 7.5 gram carbs
What is the correction factor and correction dose insulin? - it's the additional units of insulin ( correction dose) needed to bring the pt blood glucose to normal level - add the correction dose to the normal meal dose - other words: correction dose + daily meal dose
what is the difference between ICR and correction dose? - ICR: determine # gram of carbs pt can take based on his/her TDD of insulin - Correction dose: # of insulin units added to the normal units of insulin given prior to meal to bring blood sugar to normal level
what is the 1800 and 1500 correction factor rules ? - 1800 for shot acting insulin; 1800/TDD= correction factor - 1500 for rapid acting insulin; 1500/TDD=correction factor
What is the correction dose? - the correction dose= blood glucose now - target blood glucose / correction factor - the correction dose is then added to the normal daily dose
correction dose example: pt on Novolin-R 60 units. BG target 130 and current is 180; what is the correction dose? - calculate correction factor for regular insulin= 1800/60= 30 - correction dose= 180-130/30= 2 units - the total dose admin = normal daily dose + correction dose = 60+2= 62 units
When is it recommended to start insulin in type II DM? - A1c> 10% - TG> 300 - pt fails multiple regimens - start pt on 0.1-0.2 units/kg/day or 10 units/day - increase by 10-15% or 2-4 units once or twice/ week - basal-bolus still can be used if A1c is not controlled
What is the common conversion ratio for most insulin products? - 1:1 except 1- NPH ( intermediate) BID --> long acting ONCE= use 80% of TDD 2- long acting Toujeo U300 ONCE --> long acting U100 ONCE = use 80% of TDD

what are some counseling point pt should know about insulin SC injection? - rotate the site of injection -
why should the pt wash hand with warm water prior to testing and dry hand very well? - warm water: increase the blood circulation - dry hand: as water can cause reading error
what are some tips pt can follow to minimize finger pain while testing? - lance the finger on the side; fever nerves - keep hand below the heart level
what are some other alternative testing sites? - forearm - thigh - palm
what is the stability of insulin injectable drugs? - if unopened and refrigerated: stable until the expiration date - room temperature, different stability ; product specific
what is the stability of the following injectable insulin medications at room temperature? 1- Afreezza, humalog 50/50, humulin 70/30: 2- xultophy 100/3.6 3- symlin, victoza and byetta pen 4- novolin R U100, toujeo, levemir vial/pen 1-10 days 2- 21 days 3- 30 days 4- 42 days ( 6 weeks)
Which injectable insulin medication has the least stability at room temp? and which medication has the longest duration of stability? - shortest: Afrezza if opened ( 3 days) - longest: tresiba pen ( 56 days)
What is the recommended size/volume of syringe for insulin injections? - use the smallest syringe that can hold the dose - the smaller the easier to read the scale - draw up the correct dose
What is the size of the syringe to inject the following # of insulin units? 1- less than 30 2- 30-49 3- > 50 1- <30 --> use 0.3 ml 2- 30-49 --> use 0.5 ml 3- > 50 --> use 1.0 ml *** if humuLin-R U 500: use the U500 syringe
