Lab monitoring required with Clozaril  Clozapine: Monitor weekly CBC with differential, in keeping with the manufacturer's protocol. The manufacturer maintains a confidential register (800-448-5938); patients must be enrolled and have a baseline white blood cell (WBC) count and absolute neutrophil (ANC) count before initiation of therapy.  Treatment should not be initiated if the baseline WBC is <3500/mm3 or ANC is <2000/mm3. Issue of weekly supplies of the drug is dependent on the results of the weekly white blood cell count; the results are sent to the national registry via forms supplied by the manufacturer. If after 6 months of weekly monitoring, the WBC has continuously remained ≥3500/mm3 and the ANC has remained ≥2000/mm3, the monitoring of blood counts through the registry may be reduced to every 2 weeks for 6 months. If acceptable WBC and ANC counts (WBC ≥3500/mm3 and ANC ≥2000/mm3) have been maintained during the second 6 months of continuous therapy, WBC and ANC may then be monitored every 4 weeks starting at the end of the 12 months and thereafter. page 557, Edmunds, M.

Know the indications for the use of Vancomycin pg 668  Vancomycin IV is used most often in  serious or life-threatening staphylococcal or streptococcal infections.  Pseudomembranous colitis caused by C-Diff oral form when flagyl not effective  The primary care use of vancomycin is for pseudomembranous colitis caused by C. difficile. It is given in oral form when treatment with metronidazole is contraindicated or ineffective  Prevents synthesis of the bacterial cell wall by blocking peptidoglycan strand formation. 71. Know Vancomycin mechanism of action pg 668  preventing synthesis of the bacterial cell wall by blocking peptidoglycan strand formation. pg668  Prevents synthesis of the bacterial cell wall by blocking peptidoglycan strand formation. 72. Know the mechanism of action of Cephalosporinspg 678  Cephalosporins interferes with bacteria cell wall (Bacteriocidal)  Beta lactame - antibodies interfere with cell wall synthesis through inhibition of synthesis of bacterial peptidoglycan in cell wall 73. What class is erythromycin?  Macrolides Analgesia: 74. Know the side effects of Acetaminophen  When acetaminophen is used as directed, adverse effects are rare. Skin eruptions, urticaria, erythematous skin reactions and fever, increases asthma in kids,  Extremely rare hematologic reactions include hemolytic anemia, leukopenia, neutropenia, and pancytopenia. Other reactions are hypoglycemia and jaundice.  Adverse effects are usually dose dependent. Hepatic toxicity may occur following intake of >7.5 g within 8 hours.  Alcoholics and patients on hepatic metabolizing medications are more susceptible to hepatic toxicity. This is very important because hepatic toxicity can be caused by binge drinking. 75. Know the signs of Acetaminophen toxicity  Symptoms that appear in the first 24 hours are o nausea, o vomiting o drowsiness o lethargy o malaise o confusion. 76. NSAID side effects; use of topical NSAIDs  GI upset, dizziness, headaches, bleeding, fluid retention HA, increased sweating, photosensitive, rash, pruritus, urticaria, Steven Johnson's syndrome, toxic epidermal necrolysis, anaphylaxis pulmonary infiltrate, asthma, tachycardia, palpitation, HTN, MI, HF, arrhythmia, PE AFib, GI bleeding, N/V, constipation, dyspepsia. Flatulence, CVA, confusion, sedation, blurred vision, tinnitus, hearing loss, vertigo, increased LFTs low Cr hyperkalemia, renal,  Use of topical NSAIDs o Capsaicin for OA 77. Know the difference between nonselective vs selective NSAIDs pg 407  Nonselective more GI issues COX1&COX2 COX 1 responsible for GI  Selective are COX2 not as much GI issues 78. Know the Management of Osteoarthritis  APAP 1st line long term - be effective in treating the pain of OA because many patients have minimal inflammation. If not effective then  NSAIDS for flares o Intraarticular injection of steroids for knee hip mod to severe pain- NSAIDs can be used. NSAIDs are more effective than acetaminophen for OA of the knee or hip. They are also more effective in moderate to severe disease. Some patients’ conditions can be managed via long-term acetaminophen therapy with short-term use of NSAIDs for flare-ups. Because of the decreased risk of GI toxicity,  Non pharm exercise with rest weight loss o A supervised walking program can improve functional status. Recommend weight loss to overweight patients to reduce strain on joints. The patient must be realistic about the limitations of medications and about his own prognosis. (Edmunds 409)  COX-2 inhibitors are useful for long-term management of OA in elderly patients. Intraarticular injection of steroids can be provided on a limited basis. o Topical creams such as capsaicin can also help with the pain. Surgical measures such as hip or knee replacement may be necessary in joints that are seriously affected. (Edmunds 409) PPT= Aspirin and Celecoxib (cox-2) 79. Know acetaminophen toxicity, and indications in children  Acetaminophen is used commonly for pain and fever in children and generally is well tolerated. Use caution to avoid over dosage.  Acute over dosage of acetaminophen can result in hepatotoxicity and is life threatening. Toxicity is likely to occur if a patient takes more than 250 mg/kg in a single dose or greater than 12 g within a 24-hour period.  After 24 hours up until 72 hours, symptoms abate and liver toxicity (AST/ALT elevation) normally occurs. An increase in liver enzymes within 24 hours is a sign of permanent injury.  Liver enzyme elevation usually peaks at between 72 and 96 hours after ingestion, along with other markers of liver function such as the INR and a total bilirubin concentration above 4.  The last stage, which consists of recovery, lasts anywhere from 4 days to 2 weeks; recovery is complete in many cases.  The patient should immediately receive activated charcoal. Further treatment should take place in a hospital setting with the patient receiving N-acetylcysteine (NAC), the specific antidote for acetaminophen poisoning  . Acetaminophen is metabolized in the liver.  Toxic metabolite is detoxified with hepatic glutathione.  Hepatic necrosis can occur if glutathione stores have been depleted by long-term or toxic doses of acetaminophen.  Children at increased risk for acetaminophen toxicity include those with diabetes, concomitant viral infections, a family history of hepatotoxic reactions, obese children, and chronically malnourished children.  More than 250 mg/kg in a single dose or More than 12 G in 24 hours 350mg/kg severe hepatotoxicity life threatening o N/V drowsy lethargy, malaise, confusion Elevated AST, ALT Tx activated charcoal and n-acetylcysteine IV o Children: High risk for APAP toxicity Failure to give correct dose, dose may be confusing Children with DM, viral infections, family history of hepatotoxic reactions, obese, chronically malnourished at greater risk for toxicity 10-15 mg/kg oral 10-2 mg/kg rectal o Do not exceed 2.6 grams day Give every 4-6 hours [Show More]
