Study Notes
Antiplatelet Drugs and Surgery
- Aspirin should be discontinued 7 days prior to surgery to prevent prolonged platelet activity, reducing bleeding risk.
- Aspirin does not directly interact with anesthesia, nor does it exhibit prolonged anticoagulant effects.
Clopidogrel Contraindications
- Clopidogrel is contraindicated in patients with active gastrointestinal (GI) bleeds and intracranial hemorrhages, posing bleeding risks.
- Safe for patients with thyroid cancer, type 2 diabetes mellitus, and gout.
Anticoagulant Patient Education
- Patients on anticoagulants should carry medical identification cards detailing medications and dosages.
- Signs of bleeding such as bruising and tarry stools must be reported to health care providers immediately.
- Avoid over-the-counter medications and herbs unless approved, as they may interfere with anticoagulation therapy.
- Acetaminophen is preferred for pain relief; aspirin and ibuprofen should be avoided due to bleeding risks.
Thrombolytic Therapy Monitoring
- Nurses must monitor for signs of hemorrhage and vital signs during thrombolytic therapy.
- Venipuncture should be avoided during thrombolytics to minimize bleeding risks.
- Administering nonsteroidal anti-inflammatory drugs (NSAIDs) is contraindicated as they increase bleeding risks.
Warfarin Patient Guidance
- Patients on warfarin should avoid taking aspirin; acetaminophen is safe for pain.
- Increasing leafy greens in diet is inadvisable as they contain vitamin K, which can reduce warfarin's effectiveness.
- Consistent intake of vitamin K is necessary rather than increasing it.
Drug Classifications and Functions
- Cilostazol is classified as an antiplatelet drug and is also used as a vasodilator for leg conditions.
- Thrombolytics are termed “clot busters” as they dissolve existing blood clots, while anticoagulants prevent clot formation.
Monitoring Drugs
- Activated partial thromboplastin time (aPTT) is monitored for heparin therapy; international normalized ratio (INR) is used for warfarin therapy.
- A prolonged aPTT (e.g. 120 seconds) while on heparin requires immediate nurse intervention.
Adverse Effects of Clopidogrel
- Monitoring for melena (bloody stools) is crucial as it indicates potential bleeding complications from clopidogrel therapy.
Administration Routes
- Clopidogrel is administered orally, while enoxaparin (a low-molecular-weight heparin) is given subcutaneously, particularly in the abdomen.
Essential Nursing Practices
- For patients on alteplase, monitor for dysrhythmias and bleeding; avoid actions like administering vitamin K or using the Z-track method with enoxaparin.
- Patients on anticoagulants should use electric razors to minimize bleeding risk from cuts.### Atorvastatin and Muscle Pain
- Report muscle pain or tenderness in patients on atorvastatin to the healthcare provider (HCP) to prevent complications like myopathy and rhabdomyolysis.
- Resting, muscle relaxants, and ibuprofen are not appropriate treatments for rhabdomyolysis.
Nonpharmacologic Methods of Cholesterol Reduction
- Regular exercise effectively reduces cholesterol levels; it should be emphasized in teaching sessions.
- Hypnotherapy and low-sodium diets are not effective for cholesterol reduction.
- Saturated fat intake should be decreased, not increased.
Cilostazol and Licorice Consumption
- Licorice can cause hypokalemia, which may enhance the toxicity of cilostazol.
- Draw blood for potassium testing when licorice is reported in a patient taking cilostazol.
Monitoring Laboratory Values in Statin Therapy
- Monitor cholesterol, triglycerides, low-density lipoprotein (LDL), and high-density lipoprotein (HDL) levels every three months in patients on statins.
- Alanine aminotransferase (ALT), alkaline phosphatase (ALP), and gamma-glutamyl transferase (GGT) should also be routinely monitored to assess for hepatotoxicity.
- Amylase and lipase levels are not necessary unless pancreatitis is suspected; PT/INR is irrelevant for patients on statins.
Primary Causes of Peripheral Arterial Disease (PAD)
- The primary causes of PAD are arteriosclerosis and hyperlipidemia leading to atherosclerosis.
- Renal disease, protein S deficiency, and hypertension are not primary causes of PAD.
Consequences of Abrupt Statin Discontinuation
- Stopping a statin suddenly may lead to a rebound effect, increasing the risk of acute myocardial infarction.
- Statin therapy should be viewed as a lifelong commitment for maintaining lowered lipid levels.
Reducing Adverse Effects of Atorvastatin
- Recommend annual eye exams to monitor for cataract formation associated with statins.
- Regular monitoring of serum liver enzymes is essential due to potential elevations caused by statins.
- Advise patients to report any muscle weakness immediately, as it could signal rhabdomyolysis.
Patient Understanding of Antihyperlipidemic Drugs
- Patients should understand that antihyperlipidemic drugs complement other interventions aimed at lowering cholesterol.
- Patients should not double doses if missed and must not stop medications without consulting their provider.
Antidote for Warfarin Overdose
- Vitamin K is the antidote for warfarin overdose and takes 24 to 48 hours for effectiveness.
Coagulation Monitoring in Oral Anticoagulants
- Warfarin requires routine monitoring of prothrombin time and international normalized ratio (PT/INR).
- Newer anticoagulants like apixaban, dabigatran etexilate, and rivaroxaban do not require such monitoring.
Administration of Alteplase for Stroke
- Prior to administering alteplase for ischemic stroke, confirm the onset time of symptoms, as it must be given within 3 to 4 hours.
Medication Anticipation for Peripheral Vascular Disease
- Cilostazol is commonly prescribed for claudication and peripheral vascular disease due to its antiplatelet effects.
Grapefruit Juice Interaction with Atorvastatin
- Grapefruit juice can increase atorvastatin concentrations and the risk of side effects; it should be avoided.
Interventions for Antihyperlipidemic Drug Treatment
- Monitor liver function tests, including ALT and ALP, due to the risk of liver disorders.
- Patients should be counseled to follow a low-fat diet instead of a high-fat diet while being treated for high lipid levels.
