What types of medications can cause hyperglycemia?
(eg. steroids, benzodiazepines)
note: some clients may get insulin and not be diabetics but have high glucose due to steriod use.
blood glucose monitoring should be done when?
within 30 minutes before a meal (ac meal) or 2 hours after a meal (pc meal)
what colour end of test strip is inserted and what end is used to gather blood?
gold to machine, white to patient
How long are QC solutions good for?
90 days or 3 months.
24 months from manufactor (unopened)
after how many hours does a QC lockout occur of the Nova glucometer?
24 hours without test preformed
How much blood is needed for the nova glucometer to read BG
1.2 uL (pinhead sized)
whole blood =
Capillary
Venous
Arterial
Where is the best place to poke your patient for blood glucose testing?
distal segment of 3rd or 4th finger – side of finger is best
BGM steps
BGM steps (6 steps)
- prepare vascular site.
- Prepare glucometer
- Apply clean gloves
- Pierce skin with lancet device
- Wipe away first drop of blood
- Apply second drop of blood to strip
NOVA machine range
*Adult Critical Low:
<2.6 mmol/l
NOVA machine range
*Adult Critical High:
> 25 mmol/l
BGM reading
contaminating sample with interstitial fluid, will cause a false ?
false low results
BGM reading
Physiological influences that may affect results
6 things
shock, dehydration, anemia, circulatory disorders, edema, extreme hematocrit outside acceptable range 0.10 – 0.60
If patient is hypoglycemic and able to swallow, what steps should be followed?
1) Give 20 grams of fast acting carb by mouth.
-200 mL juice, 5 x 4 g glucose tablets, 4 packets of sugar, of 20 mL of honey
2) Check BG In 15 mins
If not successful after 45 mins, move to step B on hypoglycemic plan
If patient is hypoglycemic and is unconscious (without VAD access) what should the nurse do?
1) Give 1 mg of glucagon SC/IM first.
2) Notify physician STAT
3) Check glucose in 15 minutes
If patient is hypoglycemic and is unconscious and has a VAD available what should the nurse do?
1) Administer dextrose 50% injectable 10 grams IV over 2-3 mins
2) Notify physician
3) If not immediate response, administer dextrose 50 % injectable 15 grams over 2-3 mins
4) Check BG 15 mins
If a patient was treated for hypoglycemia following the hypoglycemia protocol, what should the follow up steps be for a client who is able to eat? What about if they cant eat?
CAN EAT: If meal is 1 hour away, give protein or carb snack
CANNOT EAT: maintain IV with D10W at 50 ml/hr and notify doctor for more orders

clear or cloudy
- Aspart insulin and regular Insulin are always a).. ?
- While NPH is b).. ?
a) Clear

What order do you draw clear and cloudy insulin in?
Always draw CLEAR first and then CLOUDY
When do insulin test strips expire?
3-6 months , should say on viall
basal insulin is required to
cover rise in blood glucose between meals and overnight
bolus insulin is required to
Required to cover rise in blood glucose due to meals
Pre mix insulin is used only in which type of diabetes
Type 2
the higher the ISF, the more sensitive the client is to insulin, which means?
patient requires less insulin
ISF calculation
100 divided by TDD
SC injections are absorbed more a) .. than IM
a) slowly
SC injections are administered into the a)..
a) loose connective tissue under the dermis
when is the SC route not reccomended?
severe, uncontrolled, escalating pain due to slow absorption.
generally an insulin pen needle is
4 mm – 12 mm (5/32 inch -1/2 inch)
the angle of insertion for SC injections is usually
90 degrees (though 45 degrees is also acceptable for a SC injection)
gauge
needle size ranges from
29 – 32 gauge (inner measurement or opening of needle)
What amount of medication can SC tissue hold
- only small doses (0.5 - 1 mL) of water-soluble medications should be given subcutaneously
- (but up to 2 mL is safe)
Where can you give a SC insulin injection
the outer aspect of the upper arms, anterior and lateral portions of the thigh, buttocks and abdomen
subsequent injections should be given at least
2.5 cm away from the previous site
When giving insulin, what site has the quickest absorption
the abdomen
How to use an alcohol swab for injection:
must wipe for 15-30 seconds and let dry for 30-60 seconds to be effective
