Calculate with Confidence-Chapter 17-25
-Check IV on adults -Check IV on child -Check IV for very concentrated
-Adults every 2 hours -Child every hour -Very concentrated every hour
Insulin Pumps
-Deliver rapid or short-acting insulin continuously for 24 hours a day through a catheter placed under the skin -Basal: delivered continuously -Bolus: delivered before meals meal
-Rapid-acting insulin: -Can be mixed
-Humulin R -Humulog -Novolog -Apidra
Long-acting insulin
-Lantus -Levemir
Cloudy insulin
-NPH-Can mix, combined mixture will be cloudy -Draw up clear mixable insulin first
Coumadin lab test
-PT/INR (normal rate 2-3) -Antidote is Vit. K
Heparin lab test
-PTT -Antidote is protamine sulfate -Normal range depends upon patient
Subcutaneous dosages are not to exceed:
0.5 mL
2.2 lbs = ________ kg
1 kg
Sequence for mixing insulins:
1. Gently roll vials in palm to even suspension 2. Cleanse tops of both vials with alcohol 3. Inject air equal to dose of cloudy insulin into that vial first (do not touch solution with needle) 4. Remove needle from cloudy vial 5. Using same syringe, inject air equal to needed dose into clear type mixable insulin; invert bottle and withdraw DO NOT SHAKE!!
7 Components for Medication Order: (Per Mrs. Vicky)
1. Name of Client 2. Medication 3. Dosage 4. Route 5. Frequency 6. Special Instruction 7. MD signature
Medication Order must be in this order:
1. Name of Medication 2. Dosage 3. Route 4. Frequency
7 RIGHTS
1. RIGHT CLIENT 2. RIGHT MED 3. RIGHT DOSE 4. RIGHT ROUTE 5. RIGHT TIME 6. RIGHT DOCUMENTATION 7. RIGHT PROGRAMMING (PUMP)

Calculating Heparin Examples:
20,000 units -------------- X 30 mL =. 600 units 1,000 L OR 20,000 units -------------- X 1,000 L = 600 units 30 ml
When calculating IV infusion if more than ____________ you should question it
200 mL
25,000 units Heparin 500 ml to infuse @ 17 mL/hr
25,000 units -------------- X 17 mL/hr =. 850 mL/hr 500 mL

Calculating BSA for Child Dosing Using Formula
BSA of child (m2) ------------------- X Adult dosage = 1.7 = Estimated child's dose
Formula for Calculating BSA from Pounds and Inches (Ex. calculate BSA for a adult who weighs 170 lb and is 67 inch tall
BSA= 170 (lb) X 67 (inch) / 3,131 = ___________ the hit the square root button to get final answer = 1.907 then round to nearest hundredth
Formula for Calculating BSA from Kilograms and Centimeters (Ex. calculate BSA for a child who weighs 23 kg and is 128 cm tall)
BSA= 23 (kg) X 128 (cm) / 3,600 = ___________ then hit square root button to get final answer = 0.903 then round to nearest hundredth
Insulin doses are always checked how:
BY 2 NURSES!!!
BSA
Body surface area
Sample Sliding Scale
CBG of 0-180 per dL.....No coverage CBG of 181-240 mg per dL....2 units subcut CBG of 241-300 mg per dL...4 units subcut CBG of 301-400 mg per dL...6 units subcut CBG greater than 400 per dL....8 units submit and call health care provider...Repeat CBG in 2 hr. (All above based on result of finger stick q8h)
ALWAYS DRAW UP INSULIN:
CLEAR TO CLOUDY!!
D5W
Destrose 5% in water
D5RL
Dextrose 5% and lactated Ringer (Ringer lactate)
D5 and 1/2 NS (0.45%)
Dextrose 5% in 0.45% sodium chloride
D5NS
Dextrose 5% in sodium chloride
Example of calculating BSA for Child Dose using adult dosage
Example: The prescriber has ordered a medication for which the average adult dosage is 125 mg. What is the dose a child of 1.4 (m2)? Take 1.4 (m2) / 1.7. X 125 mg (adult dosage) = 102.94 = 102.9. (always round to the tenth)

SAFETY ALERT
Nurse is responsible for administering IVF to the correct client at the right rate and monitoring response. Too rapid an infusion or inappropriate infusions can result in reactions that range from mild to fatal!!

Types of Insulin
Rapid-acting-all clear solutions 1. Humalog (lispro) 5 min. before meal -Subcut 2. Novolog (aspart) Subcut or IV 3. Apidra (glulisine) Subcut orIV Short-acting -Regular (R) takes 30 min. to work-Subcut or IV, clear Intermediate: - NPH (N) cloudy Long-acting: - LANTUS, clear, subcut only (CANNOT BE MIXED) -LEVIMIRE, clear, not as long-lasting as Lantus, may need 2 daily doses, (CANNOT BE MIXED)
RL or LR
Ringer lactate or lactated Ringer solution (electrolytes)
1/2 NS
Sodium chloride 0.45%
Insulin is given how?
Subcutaneously
Which syringe should you use to give Heparin?
TB syringe
Converting 32 lb 9 ounces to kg:
Take 9 oz./16 = 0.5625 + 32lb= 14.8 kg (always round to nearest tenth)
