Q

What are the ranges for blood glucose results for adults using a nova?

A

normal 3.3-7.0
critical low <2.6mmol/L
critical high >25mmol/L

23
Q

if a patient who has diabetes doesn’t have glucose in their urine what does that mean?

A

does not mean the person has normal blood glucose levels

24
Q

if someone has hypoglycaemia and it does not get treated what could happen?

A
  • lead to seizures, coma, death

- emergency situation

25
What are common types of insulin in regards to basal insulin?
- NPH - glargine - degludec
26
describe basal insulin
- long or intermediate acting insulin | - cover rise in BG between meals/ overnight
27
What are common types of insulin in regards to bolus insulin?
- aspart - lispro - regular
28
describe bolus insulin
- mealtime/rapid or short acting insulin | - cover rise in blood glucose due to meals
29
What are common types of insulin in regards to pre-mixed insulin?
- humalog | - humulin
30
describe pre-mixed insulin
both long-acting and short-acting
31
How often is insulin given ? What about the different types
- 1-4 times/ day - long or intermediate 1-2times/day - rapid/ short acting before meals
32
What are the nursing responsibilities for a client receiving insulin or oral hypoglycaemia agent (OHA)?
assessment - adjustment/ understand and fears about therapy - effectiveness - adverse effects patient education regarding administration evaluation of clients ability to manage therapy safely proper med admin follow up assessment
33
in regards to the nursing responsibilities for a client receiving insulin or oral hypoglycaemia agent (OHA) what needs to be included in the follow-up assessment?
- inspect injections sites - review insulation prep, storage, timing, injection technique - history of hypoglycaemic episodes - review recorded glucose tests
34
describe an insulin correction dose
- additional insulin added to the meal (bolus) does to correct elevated blood sugars - based on how sensitive a patient is to insulin - used alone (q4H) if patient is NPO
35
describe the insulin sensitivity factor (ISF)
- physician chooses ISF for client based on client's sensitivity to insulin - higher ISF more sensitive client is
36
by knowing the ISF you can calculate how much insulin will decrease blood sugar. Describe the ISF levels
- ISF 1 = 1 unit insulin decrease by 1mmol - ISF 2 = 1 unit insulin decrease by 2mmol - ISF 3 = 1 unit insulin decrease by 3mmol - ISF 4 = 1 unit insulin decrease by 4mmol
37
where do subcutaneous (SC) injections go?
loose connective tissue under the dermis
38
describe medication absorption in regards to subcutaneous (SC) injections
absorbed more slowly compared to IM route
39
when might a subcutaneous (SC) medication administration not be recommended ?
route not recommended for severe, uncontrolled escalating pain due to slow absorption
40
What are the needle size ranges for insulin pens?
- 29-32 gauge
41
How is the length of an insulin pen needle determined?
- assessment of client's adipose tissue | - 4mm-12mm
42
What angle should an insulin pen be administered?
90 degrees but 45 degrees is also ok
43
What amount of water-soluble medications should be given subcutaneously?
only small doses | 0.5-1mL
44
Why do we pinch the skin when administering a SC injection?
necessary when using a longer needle to prevent an IM injection or for a slim person
45
for insulin SC injections which site has the fasts absorption?
abdomen
46
what are sites that are acceptable to use for SC insulin injections?
- outer aspect of the upper arms | - anterior/ lateral portions of thigh, ass, abdomen
47
in regards to SC insulin injections what should the sites be free of?
- lesions - bony prominences - large underlying muscles/ nerves
48
clients with diabetes that inject insulin should practice what?
- intrasite rotation
49
what is intasite rotation?
- rotating injection sites within the same body part to provide better consistency in absorption
50
How far apart should injection sites be in regards to SC insulin
2.5cm away from previous site
51
do you need to use a disinfectant wipe to disinfect prior to a subcutaneous injection, in regards to insulin?
- not recommended for clients at home | - clean site with alcohol swab in hospital setting
52
How do you use an alcohol swab for injection?
- wipe 15-30sec - let dry for 30-60 sec - touch swab to centre of site and rotate outward in circular motion
53
Why do you need to mix insulin suspensions prior to administering?
- if not mixed amount of dispensed insulin given to client can lack by 3-6% - results in inaccurate dose of insulin
54
What are advantages of using an insulin pen vs. syringes?
- better glycemic control - increased med adherence - fewer hypoglycaemic events - reduced risk of med error - improved self management education - cost saving - improved safety for health care workers - possible decreased insulin waste - decreased nursing time
