The Process of Immunization Immunization Inserts vaccine into the body Immun/o- means immune response, and the suffix -ization means the process of creating. Also known as vaccination or inoculation Routes of administration Oral route Adenovirus Rotavirus Most vaccines cannot be given by this route because they are not absorbed from the intestines. Intranasal route One type of immunization for influenza Routes of administration Subcutaneous route Measles Mumps Rubella Varicella Herpes zoster Intramuscular route All other vaccines are given by this route.

Vaccines

Drugs that are produced and administered with the sole purpose of preventing the occurrence of a specific disease caused by a bacterium or a virus Forms Live but attenuated (weakened) bacteria or viruses Grown in several different types of cultures to weaken it Grown at temperatures that do not allow it to reproduce easily Target mutagenesis DNA/RNA mutations Less virulent Forms Intact but inactivated (killed) bacteria or viruses Killed with heat or chemicals Cannot reproduce Antigens on the outside surface of the bacteria can still provoke a response from the patient's immune system. Forms Subunits The part that contains just the antigens from the surface of a bacterium or virus Toxoids Only the toxin produced by certain gram-negative bacteria Inactivated by formaldehyde so it can no longer cause fever and infection Forms Toxoids Tox/o- means poison, and the suffix -oid means resembling. Toxoid vaccines resemble the poisonous endotoxin produced by the bacteria. Polysaccharide versus conjugate vaccines Polysaccharides Carbohydrate molecules found in the walls that surround certain bacteria Do not provoke strong immune response Conjugate (joined) vaccine Polysaccharide taken from capsule around bacterium is joined to a protein carrier. Polysaccharide versus conjugate vaccines Haemophilus influenzae type b vaccine First produced in 1987 Pneumococcal pneumonia vaccine Valence Monovalent Contain single type of antigen or strain of one pathogen Trivalent Contain three types Multivalent Contain several types Most vaccines for the "flu shot" Valence Example Gardasil is a quadrivalent vaccine. Contains four different strains of human papillomavirus infection One type of pneumococcal pneumonia vaccine contains 23 different strains; it is a 23-valent vaccine. Single versus combined vaccines -Several vaccines often combined into a single dose to avoid multiple injections -M-M-R II -Measles, mumps, and rubella -ProQuad -Measles, mumps, rubella, and varicella Booster shots -Second, third, or fourth vaccine following the initial one -Used to "boost" the immune response to that disease after some time has elapsed Example Adults should receive a tetanus vaccine booster every 10 years.

Drugs Used to Treat Obesity

Drugs used to treat obesity act in one of two ways. - They keep dietary fat from being absorbed in the intestines. - They suppress the appetite to decrease the total amount of food being eaten. Lipase inhibitor drugs for obesity -Chemically bond to the enzyme lipase -Cannot break down dietary fat in the intestines -Fat is excreted rather than absorbed. -Orlistat (Alli, Xenical) Appetite-suppressant drugs for obesity - Similar in chemistry to amphetamines, but less addictive properties - Suppress the appetite by affecting dopamine or serotonin levels in the satiety center of the brain - Also known as anorexiant drugs Appetite-suppressant drugs for obesity -Limited to short-term treatment of obesity in conjunction with dietary restrictions -If drugs are discontinued abruptly, patients may: -Develop drug dependence -Experience withdrawal symptoms Appetite-suppressant drugs for obesity Schedule III and IV drugs -Benzphetamine (Didrex) -Lorcaserin (Belviq) -Phendimetrazine (Prelu-2) -Phentermine (Pro-Fast) -Antidepressant -Bupropion (Wellbutrin) Combination drugs for weight loss Schedule IV drug and anti-seizure drug -Qsymia -Phentermine, topiramate -Narcotic antagonist and antidepressant drug -Contrave -Naltrexone, bupropion

Drugs for life-threatening cardiac arrhythmias and asystole -Asystole -Epinephrine (Adrenalin) -Stimulates the heart to beat, also helps to maintain blood pressure and blood flow to the heart and brain (improves chances of successful resuscitative efforts) Drugs for life-threatening cardiac arrhythmias and asystole -Calcium chloride -Used to stimulate the myocardium to contract more forcefully -May even stimulate a contraction when the heart is in asystole and has failed to respond to epinephrine. Vasopressor drugs -Stimulate beta1 receptors to increase the heart rate -Stimulate alpha receptors in the blood vessels to produce vasoconstriction and raise blood pressure -Maintain blood flow to the kidneys so that kidney ischemia from hypotension does not later result in renal failure Vasopressor drugs -Dopamine -Epinephrine (Adrenalin) -Isoproterenol (Isuprel) -Norepinephrine (Levophed) -Phenylephrine (Neo-Synephrine) Drugs for metabolic acidosis -During cardiac and respiratory arrest -The pH of the blood decreases rapidly. -Carbon dioxide and waste products accumulate in the blood. -In the environment of severe acidosis, the effectiveness of any emergency drug is greatly diminished. Drugs for metabolic acidosis -Sodium bicarbonate -Controversy as to the true effectiveness -May actually increase acidosis through a chemical reaction that releases more CO2 into the blood -American Heart Association guidelines recommend only using it after other measures have failed. Drugs for metabolic acidosis -Tromethamine (Tham) -Corrects the acidosis -Buffers excess hydrogen ions -Returns the blood pH to within a normal range

chapter 14 endocrine drugs

Endocrine system Consists of many glands that secrete hormones into the blood When glands malfunction, they secrete either: A decreased amount of hormone An increased amount of hormone Insulin Drugs Used to Treat Diabetes Mellitus Insulin Secreted by the beta cells in the islets of Langerhans in the pancreas Plays an essential role in glucose metabolism Lowers blood glucose levels by enabling cells to utilize glucose Insulin Transports glucose to the cell Binds with an insulin receptor on the cell membrane Transports glucose inside the cell The glucose is metabolized to provide energy. Diabetes mellitus The disease of the pancreas and body cells Type 1 The pancreas does not produce any insulin. Diabetes mellitus Type 2 The pancreas produces too little insulin. The number of or sensitivity of insulin receptors on body cells is decreased. Type 1 diabetes mellitus Previously known as: Insulin-dependent diabetes mellitus (IDDM) Juvenile-onset diabetes mellitus Treated with subcutaneously injected insulin Type 2 diabetes mellitus Previously known as: Non-insulin-dependent diabetes mellitus (NIDDM) Adult-onset diabetes mellitus Treated with antidiabetic drugs Insulin may be needed. Untreated or uncontrolled diabetes mellitus results in consistently elevated blood glucose levels. Eventually leads to the diabetic complications of: Diabetic retinopathy Diabetic neuropathy Untreated or uncontrolled diabetes mellitus results in consistently elevated blood glucose levels. Eventually leads to the diabetic complications of: Arteriosclerosis Ketoacidosis Death ( The word insulin is derived from the Latin word insula meaning island, a reference to the islets of Langerhans) (The abbreviation NPH stands for neutral protamine Hagedorn.)

Drugs Used to Treat Erectile Dysfunction****

Erectile dysfunction is the inability of a man to achieve and maintain an erection during intercourse. Sexual stimulation activates the chemical cGMP. Relaxes the smooth muscle in the arteries of the penis Increases blood flow Creates an erection --> Afterwards, enzyme PDE5 metabolizes cGMP and the erection resolves.

The Seven Rights of Drug Administration

Every year, 1.5 million people are harmed by drug errors. Institute of Medicine (IOM) recommendations All prescriptions should be created electronically drug information and inserts by standardized. Each patient has approximately one medication error per day. Archives of Internal Medicine found that drug errors occur in 1 of every 5 doses administered in the hospital. 1. The right drug Generic drug names are often complex. Trade name drugs can have similar-sounding names. 2. The right drug Check the drug name against the medication order When the drug is taken from the cart or shelf As it is being poured or placed in a paper cup Before giving it to the patient Never administer a drug prepared by another person 3. The right drug form The same generic or trade name can be manufactured in several different forms. Drug form is noted on the prescription or medication order so that there is no confusion. 4. The right drug dose Calculating drug doses is an extremely important process. Standard adult dosage is appropriate for most adults. Preset by the drug company during clinical trials Patients who fall outside the adult dosage range may need to have dose adjusted (elderly, thin, obese). 5. The right drug dose Pediatric dosages Especially for infants and premature babies Must be calculated with great accuracy Based on the total weight of the patient not the age Expressed as mg/kg/day Milligrams of drug per kilogram of body weight per 24-hour period 6. The right drug dose Chemotherapy drug doses Calculated based on the patient's total body surface area Customizes the dose for each patient to maximize the effectiveness of the drug Minimizes side effects Expressed as mg/m2 Milligrams of drug per meter squared of body surface area 7. The right route of administration Important to check the prescribed route of administration Make sure the drug form is compatible with that route. 8. The right time Measured in the frequency of dosage Number of commonly used abbreviations that indicate the frequency Based on Latin phrases Chronotherapy Attempts to coordinate administration and metabolism of a drug to the body's own biological rhythms 9. The right patient In-home situations, dispensing to yourself is not difficult. In healthcare facilities, many patients receive drugs. Patient identification becomes crucial. -social security number -name, D.O.B 10. The right documentation Only after the drug administered should the information be entered in the medical or medication administration record MAR Drug name, form, dose, unit of measurement, route of administration Signature or initials of the administering healthcare professional

Drug Alert: Prescriptions

Handwritten prescriptions can be notoriously difficult to read. Various studies have found that 5 percent or 16 percent or even 25 percent of all handwritten prescriptions are illegible. Pharmacists often become familiar with a particular physician's handwriting and can decipher illegible handwriting. --> However, when in doubt, the pharmacist always calls the physician to confirm the drug and dose. Some states, such as Florida, have passed a law that all handwritten prescriptions must be legible.

Metric system of drug measurement Invented by the French in 1790 Officially known as the International System of Units (SI) Adopted as the exclusive unit of measurement by the AMA Metric system of drug measurement Based on: Meter, for length measurements Kilogram, for weight measurements Liter, for volume measurements Metric length measurements include the meter and centimeter. A centimeter is equivalent to 1/100 of a meter. Other drug measurements Unit Some drugs are never measured by the metric system, but instead by a special designation called a unit. All types of insulin, defined on a weight basis of pure insulin Manufactured with 100 units per milliliter Abbreviated as U-100 The exact value varies from drug to drug. EX: A dose of this insulin is always measured in units. The insulin vial in this box contains 100 units of insulin per milliliter (mL) Other drug measurements Drop Abbreviated gtt Eye and ear liquid drugs prescribed as drops to be given. Other drug measurements Milliequivalent An equivalent is the molecular weight of an ion divided by the number of hydrogen ions it reacts with. A milliequivalent is 1/1000 of an equivalent. Abbreviated mEq EX: This potassium drug is measured in both milliequivalents (10 mEq).

Drug Alert GYN

Oral contraceptive drugs can have serious adverse effects, such as blood clots, stroke, and heart attack, because of their estrogen content. Because of these risks, most physicians choose to prescribe an oral contraceptive drug that contains 35 mcg of estrogen or less in each tablet. - The risk of these adverse effects increases significantly for patients who are older than 35 years of age and who smoke. All oral contraceptive drugs also carry the warning that they do not protect against sexually transmitted diseases, including HIV.

Routes of Administration for Emergency Drugs

Routes used to administer emergency drugs are different than routes normally used. -Need to have the drug take an immediate effect throughout the body Most routes result in too slow an absorption rate for the drug to produce a therapeutic effect. ------------------------------------------------------------- Intravenous route By far the most common route for administering emergency drugs -Drugs are injected by: -Intravenous (I.V.) line -I.V. push -Bolus Intravenous route Produce a maximum drug effect in the shortest period of time Following successful resuscitation, I.V. drip infusion is used. Endotracheal route Drugs are placed into an endotracheal tube. As lungs are mechanically ventilated, the drug solution is propelled into the lungs. Absorbed by the lung tissue and rapidly enters the blood Endotracheal route Therapeutic systemic drugs can be achieved. Only certain drugs can be administered by this route Intracardiac route Not used frequently, but can be valuable when other routes have failed to produce a therapeutic effect Intracardiac route If not properly placed in the left ventricle, carries the risk of: -Pneumothorax air in the heart. -Cardiac tamponade fluid in the heart. -Coronary artery laceration is a cut in the artery. -Only calcium chloride and epinephrine (Adrenalin) can be given by intracardiac administration.

Chapter 23 Vaccines

The Body's Immune Response Immune response Coordinated effort between blood and lymphatic system to destroy microorganisms that invade the body Microorganisms that cause disease are known as pathogens. Path/o- means disease. Suffix -gen means that which produces. Each type of pathogen has antigens. Immune system identifies antigens as being foreign to the body and something that must be destroyed. Once a pathogen is detected, the body attacks it in several different ways. White blood cells Antibodies Neutrophils Engulf and destroy bacteria Some bacteria release toxins that damage body tissues. Lymphocytes Mainly attack viruses NK (natural killer) cells recognize foreign cells before the body cell is coated with antibodies. Lymphocytes B lymphocytes (B cells) activate when a monocyte presents them with fragments of a bacteria or virus it has eaten. T lymphocytes (cytotoxic T cells) produce toxic granules to kill cells infected with a virus. Memory T cells are inactive until the next time the virus they were exposed to enters the body. Monocytes Engulf and destroy bacteria and virus-infected cells that have been coated with antibodies Produce interferon Produces antiviral substance that keeps viruses from entering other cells and spreading throughout the body Stimulates NK cells to attack virus-infected cells Monocytes Also, produce tumor necrosis factor that destroys endotoxins Antibodies (immunoglobulins) Produced by B lymphocytes 5 types total Immunoglobulin M (IgM)= (Think of mom the one who took care of you!!) Produced the first time the body encounters bacterium or virus Antibodies (immunoglobulins) Immunoglobulin G (IgG) Most abundant Provides active immunity Can pass from mother to fetus Immunoglobulin A (IgA) Found in body secretions, mucous membranes, and colostrum

Drug Alert.

The phrase minor tranquilizer drug is somewhat of a misnomer in that it implies that this class of drugs is somehow less effective than the major tranquilizer drugs (which are used to treat psychosis) or that the minor tranquilizer drugs are just major tranquilizer drugs given at a lower dose. - In fact, minor tranquilizer drugs are chemically unrelated to major tranquilizer drugs. Minor tranquilizer drugs are extremely effective drugs with a specific therapeutic effect for treating neurosis.

What you need to know? focus on healthcare

The use of epinephrine is contraindicated in certain areas of the body, such as the top of the nose, and the fingers and toes, and the ears, because the blood supply there is limited, and excessive local vasoconstriction would lead to necrosis and skin sloughing. In those areas, an anesthetic drug without epinephrine is used for local anesthesia. The local anesthetic drugs bupivacaine and lidocaine are available with or without epinephrine in the solution. Epinephrine (Adrenalin) is a powerful vasoconstrictor that decreases blood flow to the tissues where it is injected. This therapeutic effect controls bleeding and prolongs the anesthetic action of the drug. For centuries, the South American Indians chewed the leaves of the coca bush for their euphoric effects. Cocaine, which is derived from these leaves, was recognized as a topical anesthetic drug in 1880 and is still used as a topical anesthetic and vasoconstrictor drug for ENT procedures. (Euphoria is a desirable and natural occurrence when it results from happy or exciting events. An excessive degree of euphoria that is not linked to events is characteristic of hypomania or mania, abnormal mood states associated with bipolar disorders.)
