2. - Right-sided heart failure: Usually occurs as a result of left-sided heart failure. Lastly patients who are not mobile should be provided ted hose which are elastic stockings used to reduce pooling of blood. They should be instructed to avoid fried foods, canned foods, and packaged foods. These medications can also cause fetal toxicity which should therefore be avoided in pregnancy. In congestive heart failure (CHF), there is a lot of pressure from the peripheral veins that is being pushed on the heart. Patients with left sided HF may produce a blood tinged sputum that looks frothy and pink. They should have their head raised in bed by a 45-degree angle to reduce the swelling in the lungs. Signs and symptoms of edema should also be periodically monitored. 3. Patients with hyperkalemia may exhibit peaked T waves as well as ST wave elevation. Reducing the force and rate of heart beats acts to minimize myocardial demand or oxygen requirements. If the systolic blood pressure falls below 90 mmHg or if it decreases by 30 mmHg the medication should be halted. When the volume of blood becomes lower the kidneys will activate the Renin Angiotensin Aldosterone System to retain more fluid and cause constriction of blood vessels. The classic signs and symptoms of right sided heart failure involves the buildup of fluid in the body also described as peripheral edema. This can be caused by years of smoking leading to scarring of pulmonary tissues. Right sided heart failure describes the reduced force or strength of contraction of the right ventricle. Patients with high serum potassium should be instructed to avoid potassium rich foods like green leafy vegetables, melons, avocados, or bananas. Â. Milrinone is a positive inotropic medication (increase contractile force) which is generally reserved as a last line therapy for HF patients. This is because patients with left sided HF will experience a buildup of fluids in the lungs causing pulmonary hypertension (or high blood pressure in the lungs). Lastly, some patients may develop this kind of heart failure as a result of obstructive sleep apnea which can have different treatment modalities. This can cause dizziness when standing too quickly increasing the risk of falling. Fluid accumulation is a key adverse effect to monitor for. When the CVP measurement comes back as higher than 8 the patients may be in critical condition and provided diuretics to reduce the fluid overload. This is why having a strong understanding of HF is crucial when preparing for the NCLEX® exam. The American Heart Association wants to help you Rise Above Heart Failure (HF). These diuretics will also waste potassium potentially leading to hypokalemia. The most important consequence of HF stems from the fact that the heart will need to work harder and harder to supply the body with enough oxygenated blood. When edema symptoms are present these patients should be administered intravenous furosemide as well as morphine to reduce fluid retention and decrease myocardial oxygen demand. Orthostatic hypotension and falling is also a problem with nitroglycerin use so patients should be counseled on not changing position too quickly. This process is described as pulmonary heart disease which can be serious and potentially fatal in time. There are two different kinds of HF which can have different implications for the patient’s symptoms and progression. The spouse asks the nurse the primary cause for HF, and the … After finding simple nursing on my social media and looking at some of their content gave me the inspiration to continue my journey. Brain natriuretic peptide (BNP) is a hormone produced by the heart … The nurse performs an admission assessment for an older patient admitted to the telemetry floor. The fluid buildup can … Both medication types also cause increased excretion of sodium while retaining potassium. Most CCBs act only on the blood vessels utilizing this mechanism. Congestive heart failure (CHF) otherwise known as cardiac failure refers as the inability of the heart to pump sufficient blood to meet needs of tissues for oxygenation and nutrition. This is important as well. This test measures the central venous pressure (CVP) of the patient. Our proven system has helped over 400,000 nursing students reduce their study time, survive their SimpleNursing Premium lectures and PASS their exams! A key side of effect of ACE inhibitors is the dry cough and potentially swelling of the tongue, mouth, or airways which can be potentially life threatening also called angioedema. Therapeutic interventions for HF should result in reduced HR and resolution of edema symptoms. Examples of potassium sparing diuretics includes triamterene and amiloride. And if that happens, it will be very difficult for the heart to stretch and squeeze blood to the different parts of the body. Other disease states includes patients with coronary artery disease (CAD) or acute coronary syndrome (ACS) where the coronary arteries become narrowed or blocked with plaques reducing blood flow to the heart itself. They should be advised to reduce fluid intake by < 2 liters of fluid every day. Patients with a heart rate that drops below 60 bpm or systolic blood pressure below 100 should be held on the beta blocker. Heart failure is the inability of the heart to pump sufficient blood to meet the needs of the tissues for oxygen and nutrients.

Due to the narrow therapeutic index of digoxin serum levels should be monitored closely – especially within the first couple of weeks of initiation. A more important class to know about that is also potassium sparring are aldosterone antagonists like spironolactone. There are several different formulations of nitroglycerin – the one used in post-MI patients are the sublingual tablets used to for heart attacks. Blocking the beta receptors will result in relaxation of the heart, resulting to decreased blood pressure and heart rate. • Electrocardiogram (ECG): looks at the heart rhythm. Medical Surgical Heart failure #1 Question. Patients who have heart failure have a heart muscle that is unable to pump efficiently and this can lead to mild/severe complications. Patients with hypokalemia may require the use of potassium sparring diuretics to reduce the loss of potassium from the body. Examples of these includes nifedipine, nicardipine, and amlodipine. Less serious side effects includes headaches and facial redness or flushing. Up to a third of people with heart failure … And since the response is sympathomimetic, it’s basically the fight or flight reaction of the body which causes increased blood pressure and heart rate. These patients should also have their serum creatinine levels measured at baseline and after starting therapy to assess kidney function. And because the urinary tract primarily functions to excrete fluid from the body, it is imperative that the kidneys are properly working to relieve the heart of unnecessary pressure due to fluid overload. Patients with left sided HF may eventually develop right sided heart failure. However, there are some CCBs that can act on the heart reducing heart rate and force of contraction. See you there! - Left-sided heart failure: The heart cannot effectively pump blood out to the body. Get started now For Free.

In short, they reduce cardiac output, resistance, and workload to preserve the heart tissue. Another measurement that may come up on the NCLEX® exam called hemodynamic monitoring or Swan Ganz Cath which is usually only used in severe cases. a. systolic heart failure. Other causes may be patients with COPD or cystic fibrosis. Diuretics work by reducing the retention of water in the body to be excreted out as urine. Right-sided heart failure. A primary cause of CHF would be increased sodium in the diet. Therefore, its use has been reduced as alternative agents have been released on the market with a safer side effect profile. It covered every aspect you need to know on the physiology of heart failure… Close monitoring of heart rate should be a key monitoring parameter for these patients. What are the drugs that help in alleviating the pressure from the heart? ARB examples includes losartan, valsartan, and irbesartan which all contain the “sartan” suffix. Heart Failure can impact on a patient psychologically and socially. Therefore, calcium channel blockers block the channels responsible for heart calcification, bringing back the normal function of the heart. Examples of these CCBs are verapamil and diltiazem which can be used in patients who are not already on a beta blocker. Patients with HF should be advised to not have sex until cleared by a physician. Diuretics are effective in opening up these faucets (kidneys) to release toxins and fluids out of the body. Congestive Heart Failure (CHF) Heart failure = heavy fluid Since the heart fails to pump blood forward and now heavy fluid backs up into the lung and our body Super deadly since the patient ends up … Examples of selective beta blockers includes metoprolol, bisoprolol, and atenolol.

Non-selective beta blockers can be used in patients without COPD or asthma such as labetalol or propranolol. Signs and symptoms of severe hypotension includes lack of coordination or dizziness. An ejection fraction of 55-70% is considered normal where a fraction < 40 is very bad – termed heart failure with reduced ejection fraction (HFrEF). As a result, if patients experience these side effects that can be transitioned to an ARB which does not cause this side effect due to a difference in its mechanism. It can be challenging for these patients to deal with the consequences of their condition as well as side effects from the medications they are getting put on. The risk of digoxin toxicity increases in patients with hypokalemia (< 3.5) therefore serum potassium is important to monitor. Excess fluid can increase blood pressure as well as exacerbate HF symptoms such as edema. Other symptoms include jugular venous distension where the jugular vein bulges. 1. TED hose are critical to use in patients who are not ambulating as they can reduce the risk of a clot forming leading to other serious embolic events.

When listening to the sounds of the lungs a crackling sound also described as “rales” is observed in these patients. Calcium channel blockers (CCBs) are a common class of medication that may be used in HF patients. These patients should be weighed daily to assess for fluid retention. 2. These medications as well as ARBs act on the kidneys to ultimately block the hypertensive effects of the RAAS system. All these medications have the “pril” suffix which can help with memorization. Heart failure, also known as congestive heart failure, is recognized as a clinical syndrome characterized by signs and symptoms of fluid overload or of inadequate tissue perfusion. These work by blocking aldosterone which ultimately reduces the blood pressure while not excreting potassium. Some key adverse effects to be aware of are increased risk of falling and orthostatic hypotension. people with heart failure, but not all, have an ejection fraction of 40% or less, however, you can have heart failure with a “normal” EF. They prevent the constriction of blood vessels, decreases retention of fluid and decreased cardiac output. Copyright © 2020 SimpleNursing.com.

Beta blockers should be used with caution in asthma and COPD patients as they can cause bronchoconstriction and lead to exacerbations. Heart failure (HF) describes the inability of the heart to adequately pump blood throughout the body. On our next discussion, we’ll take an in-depth look at the mechanism of action of ACE inhibitors, beta-blockers, calcium channel blockers, and diuretics. Patients may also observe difficulty with exercise and physical activity. This is an NCLEX review for heart failure. b. diastolic heart failure. Congestion or fluid buildup in the abdomen, legs, and feet is a sign of. This helps reduce myocardial oxygen demand therefore protecting the heart with an additional mechanism.

Diuretics can also decrease the patient’s blood pressure and alter the balance of their electrolytes as they all excrete sodium as part of its mechanism. Other side effects to take note of for diuretics includes orthostatic hypotension which is low blood pressure when changing position. Heart failure is a condition that is identified as the heart’s inefficiency to pump blood supply to various areas of the body adequately. This can lead to abnormalities in the structure of the heart such as scarring of the conduction pathways (leading to atrial fibrillation) and growth/rounding of the left ventricle regarded as left ventricular hypertrophy. When trying to interpret ABGs the first step will always be to determine whether the patient has normal values, acidic, or basic (alkalotic) measurements. Diuretics are basically calming down the increased pressure being pushed on the heart to the point of normalcy. Specific patient populations may benefit from digoxin therapy as an adjunct to other treatment modalities. The basic definition of heart failure, formerly known as congestive heart failure, is the heart's inability to pump enough blood to meet the body's oxygen and nutrient demands.

Other formulations includes nitroprusside, isosorbide, hydralazine, and minoxidil. A serum creatine > 1.3 serves as a contraindication for digoxin therapy. The most commonly used diuretics to know when treating fluid overload or edema is furosemide or bumetanide. The consequence of this is that the right ventricle will have to work harder to push the blood through the lungs – overcoming the fluid overload and hypertension. As the heart must work harder in heart failure patients the myocardial tissue becomes increasingly hypoxic (starved of oxygen) – this causes stress to the tissue leading to a variety of complications. I felt like a failure. Learning Outcomes. Common side effects for CCBs includes headaches, peripheral edema, and facial flushing. It works by causing dilation of the blood vessels particularly around the heart including the coronary arteries – thereby improving blood flow to the heart. There are different types of heart failure, such as left or right-sided failure … The fluid buildup can become not only debilitating for patients but also potentially life-threatening as patients can basically drown in their own fluids. Heart failure is where the heart is too weak to pump efficiently so it can’t provide proper cardiac output to maintain the body’s metabolic … Ultimately, HF patients who have progressed too far will experience increased blood pressure, fluid retention and edema. I am proud to say that with Mike’s help I received a score of 928 on my Maternity Hesi! This blood level increases when heart failure worsens and is used to diagnose heart failure.

I am a 3rd semester nursing student and I really found this book helpful. BNP is secreted from the ventricles as they become stressed which makes BNP an important measurement to determine the severity of the patient’s condition. Patients with HF should be closely monitored for side effects and efficacy of therapy. ACE inhibitors act on the renin-angiotensin-aldosterone system (RAAS) in the kidneys, which are responsible for bringing the pressure from the peripheral veins and blood vessels to decrease the pressure experienced by the heart. Sodium restriction is a key intervention for these patients as sodium draws water into the body and leads to swelling and edema. By decreasing the amount of blood or fluid that is going inside the heart, diuretics reduce stress and workload of the heart. By using the nursing process, you can play a vital role in decreasing the exacerbation of heart failure … Heart rate should be closely monitored before and after immediately starting their therapy. Patients who are prescribed nitroglycerin should never be on Viagra (sildenafil) or Cialis (tadalafil) or “afil” drugs that are used for erectile dysfunction.

Patients should be instructed to not change position too quickly as the heart struggles to distribute blood to the brain – leading to increased risk of feinting. Alright guys, let's begin stepping up heart failure guys. In addition, reduced cardiac output will ultimately lead to sympathetic nervous system stimulation which will act to increase the heart rate of the patient and cause constriction of blood vessels. For CHF, it’s due to the ventricles inside the heart … This will increase the demand on the heart and potentially lead to damage to the heart muscles as well as conduction pathways. Posted on May 11, 2018 | by Mike Linares. Antihypertensive drugs are responsible for relieving pressure that’s being set on the heart. All Rights Reserved.
