The antagonistic agent to digoxin toxicity is what?

Angiotensin receptor blockers (ARBs) are a class of drugs that block the action of angiotensin II, a hormone that causes blood vessels to constrict and raise blood pressure. Examples of ARBs include losartan, valsartan, candesartan, and irbesartan.ARBs are used to treat hypertension, heart failure, and chronic kidney disease.

Choice A is wrong because calcium channel blockers (CCBs) are a class of drugs that prevent calcium from entering the cells of the heart and blood vessels, causing them to relax and lower blood pressure.

Examples of CCBs include amlodipine, diltiazem, verapamil, and nifedipine.CCBs are used to treat hypertension, angina, and arrhythmias.

Choice B is wrong because beta blockers are a class of drugs that reduce the heart rate and force of contraction, lowering the cardiac output and blood pressure.

Examples of beta blockers include atenolol, metoprolol, propranolol, and bisoprolol.Beta blockers are used to treat hypertension, angina, heart failure, and arrhythmias.

Choice C is wrong because platelet inhibitors are a class of drugs that prevent platelets from clumping together and forming blood clots.

Examples of platelet inhibitors include aspirin, clopidogrel, ticagrelor, and prasugrel.Platelet inhibitors are used to prevent or treat cardiovascular events such as heart attack or stroke.

Choice E is wrong because ACE inhibitors are a class of drugs that inhibit the enzyme that converts angiotensin I to angiotensin II, reducing the production of this vasoconstrictor hormone.

Examples of ACE inhibitors include lisinopril, enalapril, ramipril, and captopril.ACE inhibitors are used to treat hypertension, heart failure, and chronic kidney disease.

The nurse should contact the provider before administering furosemide because the patient has a low serum potassium level of 2.8 mEq/L, which is below the normal range of 3.5 to 5.0 mEq/L.Furosemide is a diuretic that can cause potassium loss and worsen hypokalemia, which can lead to cardiac arrhythmias, muscle weakness, and fatigue. The nurse should also monitor the patient’s blood pressure, weight, and urine output, as furosemide can lower blood pressure and cause dehydration.

Choice A. Administer medication is wrong because the nurse should not give furosemide without checking with the provider first, as it could be harmful to the patient with low potassium.

Choice C. Hold medication is wrong because the nurse should not withhold furosemide without a valid reason or an order from the provider, as it could cause fluid overload and worsen the patient’s condition.

Choice D. Give potassium supplement is wrong because the nurse should not give potassium supplement without an order from the provider, as it could cause hyperkalemia or interact with other medications.
