As in our quality study Mrs. Sharon McKenzie, a 77 year old woman, used to take daily 250 mcg of digoxin, which is a very high dose for adult perseverings. especially those, who ar patronageing from congestive c ardiac failure, like our patient Mrs. Sharon McKenzie (Neo, et al, 2010). Body receives the therapeutic effect when it stores of 8 to 12 mcg/kg generally with token(prenominal) risk of toxicity in most patients with failure of nitty-gritty and normal sinus or breathing rhythm (Mangoni, 2010).People withaffection failurewho have this digoxin are usually prescribed medications called diuretics that remove excess fluid from the part of body. This is similarly happens that many diuretics cigaret cause cat valium pass from the body (Johnson, Inder, Nagle Wiggers, 2010). Though eventually it increases the risk of digitalis toxicity. Again, our patient, Mrs. Sharon McKenzies potassium level is low 2.5 mmol/l. whereas a normal potassium level ranges from 3.5-5.0 mmol/l.You are more likely to fall into that suss out if you take digoxin, digitoxin, or other digitalismedicinesalong with the higher effective drugs that interact withit such as flecainide, quinidine, amiodarone, verapam il, and others. Similarly, Mrs. Sharon McKenzies was also taking medication with digoxin like furosemide, warfarin, and enalapril (Siabani, Leeder Davidson, 2013).In recent years the incidence of digoxin toxicity has dropped among patients in hospitals. A study has been done on 183 outpatients, who are receiving on going interference of digoxin toxicity at 10 urban and rural Department of Veterans Affairs Medical Centers in the Rocky Mountain region, to evaluate whether a mistakable decline of digoxin toxicity has occurred or not. The statistics over 1-year period, of that study is like thatOut of the 183 patients50 (27.3%) had one or more risk factors for digoxin toxicity.serum digoxin levels were elevated in 13.6% of patients.Hypokalemia in 14.3%.Elevated creatinine levels in 17.9%.And possible drug interactions in 5.5% of patients.The most common risk factor of digoxin toxicity is the patients ancient age. Like in our case study, Mrs. Sharon McKenzie is also 77-year old woman . However there are other risk factors too, which render the elderly more vulnerable to digoxin toxicity. These contain an age-related decline in renal function and a decrease in volume of digoxin distribution. There is also an increase in the number of comorbid conditions, including cardiovascular and chronic obstructive pulmonary disease, which heightens vulnerability to digoxin toxicity.Comprehensive Understanding of the Disease on Patient and FamilyDigoxin toxicity is a life-threatening condition, and when a serious disease like congestive cardiac failure caused by digoxin toxicity then it can impact severely in a bad way on a patient as well as his/her family (Betihavas, 2011). Due to which his/her family also suffer by seeing their loved one mentally disturbed. Often the patients with CHF who are depressed or who lack social support, the higher the support from the social facial expression the higher the rate of healing as the family and the patient both in complex and double trouble.Criterion-2Signs SymptomsPathophysiologySevere ventricular arrhythmiasSudden cardiac death and loss of consciousness are the basic signs and symptoms of the cardiac arrhythmias. Complaints such as dizziness, lightheadedness, fluttering, dizziness, and pounding, chest discomfort, quivering, shortness of breath, and forceful or offendful fast beats are commonly reported with arrhythmias patients. Often, patients notice arrhythmias only subsequently checking their peripheral pulses (Mudge, et al, 2010).The pathogenesis of the arrhythmias falls into one of two basic mechanisms increased or covered up automaticity, triggered application, or re-entry.Triggered activity occurs when early after depolarization and delayed after depolarization initiate spontaneous multiple depolarization, precipitating ventricular arrhythmias (Johnson, Inder, Nagle Wiggers, 2010).Arrhythmogenesis is probably the most common cognitive process and results from re-entry. It causes the change of st ate of mind and mood too.2) HyperkalemiaHigher potassium rate in your credit line can affect how your heart works. Symptoms of hyperkalemia can include brachydactylous heart rhythm arrhythmia that can be life-threateningSlowheart rateWeakness (Neo, et al, 2010)Hyperkalemia whitethorn result from an increase in total body potassium secondary to imbalance of intake vs. excretion or from misdistribution between intra- and extracellular space (Nanda, 2009).3) HypokalemiaUsually symptoms of low potassium are mildWeakness, tiredness, or pain in arms or legs muscles, sometimes this might be so severe to cause inability and disability to move arms or legs callable to weakness of muscles (much like a paralysis) (Hughes Crowe, 2010)Tingling or numbnessNausea or vomitingAbdominal cramping, bloatingConstipationPalpitations (feeling your heart beat irregularly)Urine limiting rate is too high simultaneously feeling thirsty mostly (Neo, et al, 2010).In the heart, low potassium levels make the myositis hypo-polarized or hyper excitable. Thus, arrhythmia occurs as a result of the atriums lowered membrane potential due to recovery from inactivation of the Na channel, which may trigger an action potential. In addition to this, trim potassium in the extracellular space inhibits the IKr potassium current activity, and ventricular depolarization is delayed, which thereby promotes reentrant arrhythmias (Jeon, Kraus, Jowsey Glasgow, 2010).4) Neurologic SymptomsIn the identified condition, the patient may also go through with neurologic symptoms which are Visual disturbances, disorientation, and confusion.You might experience confusion. Although rare, you might also see bright spots, have blurry vision, or experience blind spots. In addition, you might urinate much more or less than usual (Betihavas, 2011). Your body could also become swollen.The physiologies of neurological symptoms are not easy to judge and too complex and our sufferting of them are incomplete mostly. From an evolutionary perspective it is easy to judge the neurological symptoms. Though it makes whizz that the genuine physiologies of neurological symptoms are intricate and interrelated (Courtney, et al, 2009).5) Sinus Node DysfunctionSinus knob dysfunction refers to a number of conditions causing physiologically inappropriate atrial rates. Symptoms may be minimal or include weakness, effort intolerance, palpitations, and syncope. Diagnosis is by ECG. Symptomatic patients require a pacemaker.Sinus node dysfunction includes inappropriate and misbalancing the sinus bradycardia, alternating bradycardia and atrial tachyarrhythmia, sinus pause or arrest, and sinoatrial exit block (Jeon, Kraus, Jowsey Glasgow, 2010).SND also causes the abnormalities in SN impulse physical composition and propagation that also causes abnormalities in the atrium and in the conduction system of the heart (Higgins, et al, 2013). Slow ventricular rates and pauses at the time of stress is the general causes, fur thermore, it includes pastimeFatigueAnginaSyncopeDizzinessFallConfusionHeart failure symptoms and palpitationsCriterion-3Drug ClassPhysiological EffectAngiotensin-converting enzyme (ACE) inhibitorsACE inhibitors cause blood vessels broadness, further descent the amount of work the heart has to do they may also have direct beneficial cause on the heart. These drugs are diminution the symptoms and the need for hospitalization moreover they are helpful to prolong life (Mudge, et al, 2010).Beta-blockersBeta-blockers drugs lower overmatch the heart rate and block excessive blockage in the heart. They also helpful in the heart disease. These drugs are usually used with ACE inhibitors and provide an added benefit. They may temporarily worsen symptoms but result in long-term improvement in heart function (Betihavas, 2011).Although ACE inhibitors improve outcome in patients with systolic dysfunction, many patients with hypertension experience congestive heart failure due to diastolic dys function related to left ventricular hypertrophy. ACE inhibitors have been shown to reverse left ventricular hypertrophy in patients with hypertension.A meta-analysis of the effects of several antihypertensive agents suggested that ACE inhibitors were the most effective agent in reducing left ventricular hypertrophy (Katz Konstam, 2012).Beta blocker is helpful in improving the function of the failing LV and need to prevent or reverse progressive LV dilation, sphericity, chamber and hypertrophy. Beta blockers also lower down the heart beating rate and LV wall stress. According to recent studies from laboratories have also proven that beta blockers can satisfy cardiomyocyte apoptosis in HF. These are the basic advantages and benefit of beta-blocker for the patient of heart at any higher stage (Katz Konstam, 2012).Criterion-4As a registered nurse, my care plan for a patient suffering from Congestive Cardiac Failure with digoxin toxicity would be like, (Driscoll, et al, 2009)Intervent ions-RationalesI realize that I would hold the medication Due to possibility of toxicityWait for Electrolytes and digoxin test, as these tests were already ordered for our patient electrolytes can affect the action of dig and cause dysthymias and to find out the level of digMonitor I O monitoring for renal functionMonitor for edema and auscultator the lungsMonitor symptoms, VS S/E of dig toxicityCall the doctor. To get orders to carry out interventions and inform doctorStart an IV. For administration of medications (Mudge, et al, 2010).Comprehensive Treatment of the Identified ConditionThe main goal of treatment is to correct cardiac toxicity.If the person has stopped breathing, as our patient Mrs.Sharon McKenzie confronting with shortness of breath, startCPRand get emergency medical help (Betihavas, 2011).Initial treatment includesGeneral supportive care discontinuance of digoxin therapy and prevention of further exposureAdministration of digoxin-specific antibody fragments (digoxin immune Fab)Treatment of specific complications for example, dysrhythmias and electrolyte abnormalities (Jeon, Kraus, Jowsey Glasgow, 2010).Supportive careGeneral supportive care includes attaching patients to a cardiac monitor, providing IV fluids in patients with hypotension or volume depletion (with caution for patients with CHF), supplemental oxygen, and/or repletion of electrolytes in patients with electrolyte abnormalities (Mudge, et al, 2010).Electrolyte abnormality managementIn case of Mrs. Sharon McKenzie, hyperkalemia is only change by reversal (e.g., with insulin/glucose) if it is considered life-threatening, because of the risk of producing hypokalemia, because her potassium level is low i.e. 2.5 mmol/l. One study showed that insulin interacts directly with Na(+)/K(+) ATPase pump and alters the effect of digoxin (Betihavas, 2011). This supports the finding that for patients with diabetes, insulin has been shown to have cardio protective effects after digoxin in toxication. Calcium is not used to treat hyperkalemia in patients with suspected digoxin toxicity as it may induce arrhythmia or cardiac arrest.Bradycardia managementAs Mrs. Sharon McKenzies ECG report showed sinus bradycardia, this will be treated with atropine. Atropine can be given every 3 to 5 minutes until there is a response or the 3 mg maximum dose is reached (San Miguel, et al, 2013).Hemodynamic compromise managementAs Mrs. Sharon McKenzie has signs of hemodynamic insufficiency and/or compromise (e.g., hypotension, altered consciousness or dizziness), digoxin immune Fab is given as primary management (Mudge, et al, 2010).Ongoing monitoring and change of medicineIdeally, digoxin is discontinued and a different medicine for rate control or a different inotrope prescribed (for AF, atrial flutter or CHF, respectively). If the patient has to keep on on digoxin for some reason, then the dose of digoxin is adjusted for the patients medication profile (Edgley, Krum Kelly, 2012).Re ferencingJeon, Y. H., Kraus, S.
