Full Answer
Which is a potassium-sparing diuretic used in the treatment of heart failure (HF)?
Which is a potassium-sparing diuretic used in the treatment of heart failure (HF)? Spironolactone (Aldactone) A patient is prescribed digitalis preparations.
How do diuretics prevent death in heart failure?
Mechanisms The mechanism by which diuretics prevent death is unclear because the cause and mode of death is often not described in these trials. Differentiation between death due to progressive congestive heart failure and an opportunistic arrhythmia is not possible.
What are the most likely diuretics to be used in critically ill patients?
Fast-acting, potent diuretics such as furosemide and bumetanide are the most likely diuretics to be used in critically ill clients (e.g., those with pulmonary edema). A male client has cirrhosis and is receiving diuretic therapy. The nurse knows that what drug will help prevent metabolic alkalosis or hypokalemia in this client?
What medication is given to a patient with heart failure?
Morphine sulfate The physician writes orders for a patient to receive an angiotensin II receptor blocker for treatment of heart failure. What medication does the nurse administer? Valsartan (Diovan) The nurse is discussing cardiac hemodynamics with a nursing student.

What is the primary benefit of spironolactone aldactone in patients with heart failure?
One study3 has shown that spironolactone improves morbidity and mortality in patients with severe heart failure. The particular advantages of spironolactone for prevention are that it is inexpensive, is taken once daily and has relatively few side effects.
Which diagnostic study is usually performed to confirm the diagnosis of heart failure?
an electrocardiogram (ECG) – this records the electrical activity of your heart to check for problems. an echocardiogram – a type of ultrasound scan where sound waves are used to examine your heart.
Which of the following describes difficulty breathing when lying flat?
Sometimes, people find it hard to breathe when they are lying down flat. The medical term for this is orthopnea.
Which is a potassium-sparing diuretics?
Examples of potassium-sparing diuretics include: Amiloride (Midamor) Eplerenone (Inspra) Spironolactone (Aldactone, Carospir)
Is spironolactone a potassium-sparing?
Spironolactone is a potassium-sparing diuretic (water pill). It prevents your body from absorbing too much salt and keeps your potassium levels from getting too low. This medicine is also used to treat or prevent hypokalemia (low potassium levels in the blood).
What is the best treatment for heart failure?
Medicines are the main treatment for heart failure, but for some people surgery may help. Operations that can help with heart failure include: heart valve surgery. a coronary angioplasty or bypass.
What is the first line treatment for heart failure?
After a patient has been diagnosed with a type, stage, and class, treatment can be determined. First-line drug therapy for all patients with HFrEF should include an angiotensin-converting enzyme (ACE) inhibitor and beta blocker. These medications have been shown to decrease morbidity and mortality.
What is treatment for heart failure?
Doctors usually treat heart failure with a combination of medications. Depending on your symptoms, you might take one or more medications, including: Angiotensin-converting enzyme (ACE) inhibitors. These drugs relax blood vessels to lower blood pressure, improve blood flow and decrease the strain on the heart.
What does a cardiac cough sound like?

And then the cough mechanism is activatedMoreAnd when that happens people start getting breathless. And then the cough mechanism is activated just to try and clear the airways. And that's how you get what we call a cardiac cough.
What is a cardiac cough?
It's a type of coughing or wheezing that occurs with left heart failure. Depending on how severe the symptoms are, this wheezing can be a medical emergency. Heart failure can cause fluid to build up in the lungs (pulmonary edema) and in and around the airways.
Can sitting too much cause shortness of breath?
Sometimes, shortness of breath can even strike while you're at rest, for instance when you're sitting at your desk at work. Prolonged sitting can cause shortness of breath due to bad posture.
What is the mainstay of diuretic therapy for HF?
In general, due to their greater effectiveness, loop diuretics, such as furosemide, are the mainstay of diuretic therapy in HF.
Why do we need diuretics?
Diuretics are used to achieve and maintain euvolaemia (the patient’s ‘dry weight’) with the lowest possible dose. This means that the dose must be adjusted, particularly after restoration of the dry body weight, to avoid the risk of dehydration, which leads to hypotension and renal dysfunction.[10] .
What are the different types of loop diuretics?
Loop diuretics include furosemide, bumetanide, torsemide and ethacrynic acid. While the bioavailability of oral furosemide ranges from 40 to 80 %, the bioavailability of torasemide and bumetanide exceeds 80 %; so these two molecules may be more effective in treating patients suffering from HF.[7]
What is loop diuretic?
Loop diuretics remain a cornerstone in the pharmacological treatment of ADHF and are administered in about 90 % of patients hospitalised for HF.[1] . These drugs are routinely used as initial therapy in ADHF due to their ability to greatly improve the symptoms.
How much sodium is reabsorbed in the collecting duct?
Only 3 % of filtered sodium is reabsorbed at the collecting duct, so this class of drugs does not have an appreciable diuretic effect. However they are often used in association with other more effective diuretics to correct or prevent potassium deficiency.
Why are sodium ducts less effective in glomerular filtration?
They are less effective in patients with reduced glomerular filtration, because they exert their diuretic effects from the luminal side of the nephron.
What is the most common cause of hospitalisation in patients over the age of 65?
HF is the most common cause of hospitalisation in patients over the age of 65.[2] . The main manifestations of the syndrome are symptoms resulting from vascular congestion, such as shortness of breath, abdominal distension, oedema formation and symptoms resulting from low systemic perfusion.
