What are they and what signs and symptoms would we see?
What do we as nurses do;
- prevent and/ or manage these?]]> 2023-03-21 09:01:37 UTC https://padlet.com/stephanieandrews/t29i5rlaudmt4u3x/wish/2525018768 Compare and contrast the significant risks for each of the drug classes stephanieandrews https://padlet.com/stephanieandrews/t29i5rlaudmt4u3x/wish/2525018769 What were your significant risks? Why are they significant?
Do you understand the MoA of how the patient might develop the risk?
Did you need to go and look them up again? ]]> 2023-03-21 09:01:37 UTC https://padlet.com/stephanieandrews/t29i5rlaudmt4u3x/wish/2525018769 Question: stephanieandrews https://padlet.com/stephanieandrews/t29i5rlaudmt4u3x/wish/2525018770 What is the purpose and benefit of administering the loading dose of amiodarone prior to commencing an infusion? ]]> 2023-03-21 09:01:37 UTC https://padlet.com/stephanieandrews/t29i5rlaudmt4u3x/wish/2525018770 Consider??? stephanieandrews https://padlet.com/stephanieandrews/t29i5rlaudmt4u3x/wish/2525018771 Note: Always consider:
Is there anything in the patient's condition/ past history that may increase the risks?

What is the patients past history? ]]> 2023-03-21 09:01:37 UTC https://padlet.com/stephanieandrews/t29i5rlaudmt4u3x/wish/2525018771 Group 4 stephanieandrews https://padlet.com/stephanieandrews/t29i5rlaudmt4u3x/wish/2525018772 2023-03-21 09:01:37 UTC https://padlet.com/stephanieandrews/t29i5rlaudmt4u3x/wish/2525018772 Group 5 stephanieandrews https://padlet.com/stephanieandrews/t29i5rlaudmt4u3x/wish/2525018773 The loading dose of amiodarone is the initial higher dose given to rapidly achieve therapeutic levels of the drug in the body. 

This loading dose is typically given to treat life-threatening arrhythmias or cardiac arrest, after which the maintenance dose of the medication is given to maintain the desired effect. 

The loading dose of amiodarone is typically 800-1600 mg/day, which is given intravenously (IV) over a period of several hours or divided into smaller doses over a period of days. After the loading dose, the maintenance dose of amiodarone is typically around 200-400 mg/day, which can be given orally or intravenously depending on the patient's condition. 

The specific dosing regimen of amiodarone may vary depending on the patient's medical history, age, weight, and other factors, and should be determined by a healthcare provider.]]> 2023-03-21 09:01:37 UTC https://padlet.com/stephanieandrews/t29i5rlaudmt4u3x/wish/2525018773 Group 2 stephanieandrews https://padlet.com/stephanieandrews/t29i5rlaudmt4u3x/wish/2525018774 2023-03-21 09:01:37 UTC https://padlet.com/stephanieandrews/t29i5rlaudmt4u3x/wish/2525018774 Group 3 stephanieandrews https://padlet.com/stephanieandrews/t29i5rlaudmt4u3x/wish/2525018775 An initial, larger dose of a medication that is administered to rapidly achieve a therapeutic concentration of the drug in the body.
Benefits include ...
- Rapid onset of therapeutic effect: Achieve a therapeutic concentration of the drug in the body more quickly than a maintenance dose. 
- Improved efficacy: Achieving a therapeutic drug concentration more quickly, a loading dose can improve the efficacy of the medication
- Decreased risk of adverse effects: the therapeutic concentration is reached more quickly, reducing the time during which the drug concentration is increasing and decreasing the risk of adverse effects.
- Greater patient satisfaction: achieves desired outcome quicker.]]> 2023-03-21 09:01:37 UTC https://padlet.com/stephanieandrews/t29i5rlaudmt4u3x/wish/2525018775 Case Scenario stephanieandrews https://padlet.com/stephanieandrews/t29i5rlaudmt4u3x/wish/2525018776 2023-03-21 09:01:37 UTC https://padlet.com/stephanieandrews/t29i5rlaudmt4u3x/wish/2525018776 Scenario continued stephanieandrews https://padlet.com/stephanieandrews/t29i5rlaudmt4u3x/wish/2525018777 2023-03-21 09:01:37 UTC https://padlet.com/stephanieandrews/t29i5rlaudmt4u3x/wish/2525018777 stephanieandrews https://padlet.com/stephanieandrews/t29i5rlaudmt4u3x/wish/2525018778 2023-03-21 09:01:37 UTC https://padlet.com/stephanieandrews/t29i5rlaudmt4u3x/wish/2525018778 Group 1 stephanieandrews https://padlet.com/stephanieandrews/t29i5rlaudmt4u3x/wish/2525018779 Amiodarone may increase metoprolol’s concentration and increase the risk of severe bradycardia. The nurse should consider starting at a low dose and carefully monitor for toxicity and bradycardia. Monitor BP and heart rate. given amiodarone and metoprolol both increase this risk. Monitor the heart rate carefully and consider the need to withhold a dose if heart rate falls below 60 bpm. 

Temazepam increases risk of respiratory depression, renal and hepatic impairment. As the amiodarone can also worsen hepatic and renal impairment, careful monitoring is required when administering both drugs. Enoxaparin also increases risk of hepatic and renal toxicity. 

Monitor LFTs, renal function, lung function (including chest x-rays) and electrolyte levels throughout treatment. ]]> 2023-03-21 09:01:37 UTC https://padlet.com/stephanieandrews/t29i5rlaudmt4u3x/wish/2525018779 stephanieandrews https://padlet.com/stephanieandrews/t29i5rlaudmt4u3x/wish/2525018780 2023-03-21 09:01:37 UTC https://padlet.com/stephanieandrews/t29i5rlaudmt4u3x/wish/2525018780 Group 2 stephanieandrews https://padlet.com/stephanieandrews/t29i5rlaudmt4u3x/wish/2525018781
Amiodarone may increase metoprolol’s concentration,
- increasing the risk of severe bradycardia
- consider using a low dose to start metoprolol treatment
- monitor patient carefully.

Mechanism of action: it will decrease SA mode automaticity and slows AV conduction thus decreasing heart rate.
Adverse effect: worsening of arrhythmia, pulmonary toxicity and hypotension.

Potassium chloride - should not be administered by bolus and it should be dilluted and infused slowly by an infusion pump. It may cause life threatening arrhythmia and also ensure to check hospital policy and procedure before administering IV KCL. 

Magnesium sulfate is also given for patient with arrhythmia to aid in optimal cardiac conduction. ]]> 2023-03-21 09:01:37 UTC https://padlet.com/stephanieandrews/t29i5rlaudmt4u3x/wish/2525018784 Group 5 stephanieandrews https://padlet.com/stephanieandrews/t29i5rlaudmt4u3x/wish/2525018786 Amiodarone (anti-arrhythmic)
- Other antiarrhythmic drugs such as quinidine, procainamide, sotalol, and dofetilide, which can increase the risk of arrhythmias or prolong the QT interval.
- Drugs that inhibit the metabolism of amiodarone, such as cimetidine, diltiazem, verapamil, and grapefruit juice, which can increase the levels of amiodarone in the body and increase the risk of side effects
- Drugs that induce the metabolism of amiodarone, such as rifampin, phenytoin, and carbamazepine, which can decrease the levels of amiodarone in the body and reduce its effectiveness.
- Warfarin and other anticoagulants, which can increase the risk of bleeding due to amiodarone's effects on blood clotting.
- Digoxin, which can increase the levels of digoxin in the body and increase the risk of toxicity.
- Statins and other lipid-lowering drugs, which can increase the risk of muscle damage due to amiodarone's effects on muscle metabolism.


temazepam (benzodiazepines)
- Benzodiazepines and other sedatives: can increase the risk of excessive sedation, respiratory depression, and coma.
- Alcohol: can increase the sedative effects of the medication and cause respiratory depression.
- Opioids: can increase the risk of respiratory depression, coma, and death.
- Antipsychotics and antidepressants: can increase the risk of sedation, respiratory depression, and other side effects.


enoxaparin (anticoagulant)
- Anticoagulants and antiplatelet drugs: can increase the risk of bleeding.
- Nonsteroidal anti-inflammatory drugs (NSAIDs): can increase the risk of bleeding when used with enoxaparin.
- Thrombolytic agents: can increase the risk of bleeding.
- Heparin: can increase the risk of bleeding and heparin-induced thrombocytopenia.
- Warfarin: can increase the risk of bleeding.
- Certain antibiotics: increase the risk of bleeding, such as penicillins and cephalosporins.


metoprolol (beta-blocker)


amlodipine  (calcium channel blocker)
- CYP3A4 inhibitors: such as clarithromycin, erythromycin, and grapefruit juice, can increase the levels of amlodipine in the blood and increase the risk of side effects.
- CYP3A4 inducers: such as rifampin and St. John's wort, can decrease the levels of amlodipine in the blood and reduce its effectiveness.
- Beta-blockers: can increase the risk of low blood pressure, heart failure, and bradycardia.
- ACE inhibitors and angiotensin receptor blockers (ARBs): can increase the risk of low blood pressure and kidney damage.
- Digoxin: Amlodipine can increase the levels of digoxin in the blood and increase the risk of digoxin toxicity.
- Cyclosporine: can increase the levels of both drugs in the blood and increase the risk of side effects.
