1. NURSING MATHEMATICS AND SCIENCE THE FOUNDATION OF NURSING

2. MATH Considered one of the critical skills necessary to practice in the nursing profession

3. BASIC MATH 1.Add, subtract, multiply and divide whole numbers 2.Add, subtract, multiply and divide fractions 3.Add, subtract, multiply and divide decimals

4. ALGEBRA 1.Set up and solve ratio and proportion problems 2.Convert from one system of measure to another

5. SYSTEMS OF MEASURE 1.Metric System 2.Apothecary System 3.Household system

6. WEIGHT METRICAPOTHECARYHOUSEHOLD 454 grams16 ounces1 pound 1 Kilogram2.2 pounds

7. VOLUME METRICAPOTHECARYHOUSEHOLD 1 milliliter(ml)15-16 minims(m)15-16 drops(gtt) 4 milliliters(ml) (cc) 1 dram or 4 ml’s or cc’s 1 teaspoon(t), 60 drops

8. ORDER: Give Fentanyl 5 mg/hr. The bag is labeled 250 mg in 500 ml of solution. How fast will the IV need to be infused to give The correct dose? IV DRUGS

9. 5 mg = 250 mg 5 (500) = 250 x 2500 x= 10ml/hr x ml 500 ml 250 RATIO AND PROPORTION

10. When the order is written as unit of measurement/Kg of wt/minute The order is Dopamine 20mcg/Kg/minute. The bag is labeled Dopamine 100 mg/50 ml. The patient weighs 88 lbs. How fast will the IV run to give the dose? 1.First because the weight is in lbs, you must convert lbs. to Kg. (88 lbs = x Kg) 2.Find the hourly dose. The order is written in mcg/Kg/min you multiply by 60minutes to get the hourly dose. 20mcg x 40 Kg x 60 =48,000mcg/hr

11. Continued 3.Note that the concentration is in mg/ml not mcg, so you must convert to obtain like units of measure. 100 mg = 1mg x= 100,000 mcg/ml x mcg 1000 mcg

12. CONTINUED, PAGE 2 4. Lastly set the problem up in ratio and proportion. 1000,000 mcg = 48,000 mcg/hr 50 ml x ml 1000,000x = 24 ml/hr IV rate

13. MY DAY Counting is a very important issue in my area of practice. The return of all sharps, sponges, and instruments is a necessity for a positive outcome for the patient

16. ANATOMY STUDYING THE HUMAN BODY BONES MUSCLES TENDONS VESSELS JOINTS SYSTEMS*

17. PANCREAS AND DIGESTIVE SYSTEM

18. PHYSIOLOGY To study how the human body functions

19. FUNCTION OF THE PANCREAS/AND THE DIGESTIVE SYSTEM

20. WHAT THE PANCREAS DOES The pancreas secretes various substances such as digestive enzymes, insulin, and glucagon which empties into the duodenum(small bowel). Digestive enzymes catalyze reactions so the body can utilize food as fuel. Insulin is a hormone secreted by the beta cells of the islets of Langerhans in the pancreas

21. WHAT THE PANCREAS DOES This secretion is in response to increased levels of glucose in the blood. Insulin also regulates the metabolism of glucose and and the processes necessary for the metabolism of fats, carbohydrates, and proteins. Insulin lowers blood glucose level and promotes transport and entry of glucose into the muscle cells and other tissues. Uncorrected severe deficiency of insulin is incompatible with life

22. PATHOPHSIOLOGY To study the biologic and physical manifestations of disease It explains the processes within the body that result in the signs and symptoms of a disease

23. DIABETES Is a complex disorder of carbohydrate, fat, and protein metabolism that is the result of a deficiency or complete lack of insulin secretion by the beta cells of the pancreas. The eyes, kidneys, nervous system, skin, and circulatory system may be affected by the long term complications

24. DIABETES TYPES TYPE I Is an autoimmune process and is dependent on insulin, diet, and exercise. TYPE II Is developed from heredity, obesity, sedentary life style, high-fat, low-fiber diets, hypertension, and aging. May need insulin, but not dependent, and oral agents, diet and exercise.

25. PHARMACOLOGY Learning the properties, uses, and actions of drugs

26. MEDICATION Insulin comes many different mixtures. They work at different times and are given in different dosages. The number of times insulin is given vary depending on diet, activity, stress, and medical implications. Oral diabetic agents stimulates the pancreas to produce insulin, helps body produce less sugar, slows the digestion of carbohydrates, decrease peaks in blood sugar levels after eating

27. CLINICAL NUTRITION To study the processes involved for proper body functioning and maintenance of health

28. PEANUT BUTTER vs. ORANGE JUICE

29. CHEMISTRY The science dealing with the elements, their compounds, and the molecular structure and interactions of matter

30. CHEMISTRY ORGANIC Animals and plants DOES contain carbon INORGANIC Sand, salt, iron NO hydrocarbons

31. MICROBIOLOGY Studying of microorganisms that include bacteria, algae, protozoa, and fungi
