Exam 1 - Study Material Flashcards
(274 cards)
What should the nurse consider before giving insulin to a patient?
- Always check the blood sugar before giving insulin
- Know onset and duration of insulins
- Always have another nurse check what is drawn, the amount, etc.
How should insulin be administered?
- Using thumb and forefinger, pinch skin at the injection site. Inject at 90 degree angle. DO NOT ASPIRATE FOR BLOOD RETURN
- Place alcohol swab or cotton over site and withdraw needle
- DO NOT MASSAGE area after injection
- Dispose of needle in appropriate puncture resistant container
How should pre-filled syringes of insulin be stored and how long are they stable?
- Pre-filled syringes store in vertical position in refrigerator.
- Stable x1 week-max 2 wks
What types of insulin are there, and what is the onset and duration for each?
- Rapid acting/Short duration (10-30min / 3-6.5hr)
- Slower acting/Short duration (30-60min / 6-10hr) regular & (15-30min / 6.5hr) exubera
- Intermediate duration (60-120min / 16-24hr)
- Long duration (70min / 24 hr)
What are some Rapid acting/Short duration insulins?
- lispro (Humalog)
- aspart (NovoLog)
- glulisine (Apidra)
What are some nursing implications of Rapid acting/Short duration insulins?
- Give with meals to control postprandial rise in glucose to control glucose between meals & HS
- If no food is given within a short perioid of time pt. will get in a hypoglycemic state.
- All of them are clear solutions –> look out for cloudiness
- All 3 require prescriptions (Insulin Lispro, Aspart & Glulisine)
- Do NOT give IV
What are some adverse effects of insulin?
- Hypoglycemia
- edema
- weight gain
What are some Slower acting/Short duration insulins?
- Humulin R (regular human insulin)
- Novolin R
- Exubera
What are some nursing implications of Slower acting/Short duration insulins?
- Humulin & Novolin R do not need an Rx to get, **except Exubera **
- SQ inj, SQ infusion, IM inj, oral inhalation & off label IV
- Only insulin given by IV
- Can be inhaled or injected AC to control postprandial hyperglycemia
- Infused SQ to provide basal glycemic control
What are some Intermediate duration insulins (NPH insulins)?
- Humulin N
- Novolin N
What are some nursing implications of Humulin N & Novolin N insulins?
- Cloudy suspension should be gently shaken b/4 administration
- Available without prescription
- The protamine component slows absorption & delays DOA
- Do not administer at mealtime but use bid between meals & at bedtime
-
Is the only long acting insulin that can be mixed with a short acting insulin
- Draw short acting insulin into syringe first to avoid contamination of NPH vial.
- If have to give a short acting & long acting insulin mix the preparations rather than inject them separately.
What are some long duration insulins?
Insulin Glargine (Lantus)
What are the nursing implications of Insulin Glargine (Lantus)?
- Clear colorless solution, do NOT mix with other insulins and do NOT give IV
- Long DOA 24 h, qd dosing SQ injection
- Because of long DOA and a stable steady state there is less risk of hypo or hyperglycemia.
You should Discard insulin that has any precipitate except for which type of insulin?
NPH insulins (Humulin N & Novolin N)
What is Insulin Release Stimulated By?
- Glucose
- Ketone Bodies
- Proteins
- Glucagon
- Gastric Secretions
- Salicylates- asprin – can lead to hypoglycemia
- Hyperkalemia
What is Insulin Release Inhibited by?
- Hypoglycemia
- Hypokalemia
- Catecholamines (NE and Epi
- Beta-Blockers
- Calcium Channel Blockers
- Phenytoin
- Alcohol (this will decrease glucose levels for a while)
What is glycogenolysis?
breakdown of hepatic and muscle glycogen to glucose.
What is gluconeogenesis?
conversion of fatty acids and protein to glucose. Ketone bodies are created during this process
What are the Signs & Symptoms of High glucose levels?
- Increased urination (Polyuria)
- Increased thirst (Polydipsia)
- Increased hunger (Polyphagia)
- Weight loss
- Weakness and fatigue
- Blurred vision
What are the SQ injection sights for insulin?
- upper arm, thigh (slowest) & abdomen (fastest)

What type(s) of insulin can be given IV and why is it given?
- ONLY Regular insulin can be given IV.
- Usually given for ketoacidosis or hyperkalemia
- Insulin is given to ALL pts. that have type I
In what situations would you want to supplement additional doses of insulin?
- During infection
- stress obesity
- the adolescent growth spurt
- pregnancy (after 1st trimester)
What are some Nursing Diagnoses for anemia?
- Activity intolerance
- Imbalanced nutrition: Less than body requirements
- Knowledge deficit
- Noncompliance with prescribed therapy
- Altered tissue perfusion
- Fatigue
What are the 2 types of diabetes mellitus?
- Type 1 (Beta-cell destruction, usually leading to absolute insulin deficiency)
- Type 2 (ranging from predominatly insulin resistance with relative insulin deficiency to predominattly an insulin secretory defect with insulin resistance)
