The antagonistic agent to digoxin toxicity is what?
Protamine sulfate.
Acetylcysteine.
Antidigoxin.
Activated charcoal.
The Correct Answer is C
Antidigoxin is an antidote for digoxin toxicity that binds and inactivates digoxin, a cardiac glycoside that can cause life-threatening arrhythmias, hyperkalemia, and other symptoms when overdosed. Antidigoxin is also known as digoxin immune Fab or DIGIFab.
Choice A, protamine sulfate, is wrong because it is an antidote for heparin, an anticoagulant that can cause bleeding when overdosed.
Choice B, acetylcysteine, is wrong because it is an antidote for acetaminophen, a painkiller that can cause liver damage when overdosed.
Choice D, activated charcoal, is wrong because it is a nonspecific adsorbent that can reduce the absorption of some drugs or poisons from the gastrointestinal tract, but it is not effective for digoxin toxicity.

Correct Answer is A
Explanation
Lisinopril belongs to the class of drugs calledangiotensin-converting enzyme (ACE) inhibitors.ACE inhibitors work by blocking the enzyme that converts angiotensin I to angiotensin II, a hormone that causes blood vessels to narrow and raise blood pressure.By inhibiting this enzyme, ACE inhibitors relax and widen the blood vessels, lower blood pressure, and improve blood flow to the heart and kidneys.
Choice B.Candesartan is wrong because it belongs to the class of drugs calledangiotensin II receptor blockers (ARBs).ARBs work by blocking the action of angiotensin II on its receptors, preventing it from causing blood vessel constriction and high blood pressure.ARBs are similar to ACE inhibitors in their effects, but they do not affect the enzyme or the level of bradykinin, a peptide that can cause cough and angioedema as side effects of ACE inhibitors.
Choice C.Metoprolol is wrong because it belongs to the class of drugs calledbeta blockers.Beta blockers work by blocking the effects of adrenaline and other hormones that stimulate the heart and blood vessels, causing them to beat slower and with less force.Beta blockers lower blood pressure and reduce the workload on the heart.
Choice D.Amlodipine is wrong because it belongs to the class of drugs calledcalcium channel blockers.Calcium channel blockers work by blocking the entry of calcium into the muscle cells of the heart and blood vessels, causing them to relax and dilate.Calcium channel blockers lower blood pressure and improve blood flow to the heart.
Normal ranges for blood pressure vary depending on age, gender, and other factors, but generally, a systolic blood pressure (the top number) of less than 120 mmHg and a diastolic blood pressure (the bottom number) of less than 80 mmHg are considered normal for adults.A blood pressure of 130/80 mmHg or higher is considered high and may require treatment with medication.
Correct Answer is C
Explanation
Phenazopyridine hydrochloride (Pyridium) is a urinary tract analgesic that can relieve the pain, burning, and discomfort caused by infection or irritation of the urinary tract.However, it can also cause some side effects, one of which is changing the color of bodily secretions to reddish orange. This is due to the excretion of the drug in the urine, saliva, sweat, and tears.The color change is harmless and usually disappears when the drug is stopped.
Choice A is wrong because phenazopyridine does not change bodily secretions to alkaline.In fact, it may interfere with the urine test that measures acidity (pH) and glucose.
Choice B is wrong because phenazopyridine does not change bodily secretions to pinkish.However, some other drugs, such as rifampin and doxorubicin, may cause urine to turn red or pink.
Choice D is wrong because phenazopyridine does not change bodily secretions to black.However, some other drugs, such as metronidazole and nitrofurantoin, may cause urine to turn brown or dark yellow.
Some other common side effects of phenazopyridine include headache, dizziness, indigestion, and stomach pain.Some serious side effects include skin itching, interference with the oxygen-carrying capacity of red blood cells, hemolytic anemia, and renal and hepatic toxicity.
These problems are more common in people who have existing kidney problems or take more than recommended.If you experience any of these symptoms, stop taking phenazopyridine hydrochloride and talk to a healthcare provider right away.
