The antagonistic agent to digoxin toxicity is what?

Protamine sulfate.

Acetylcysteine.

Antidigoxin.

Activated charcoal.

Answer and Explanation

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

Terazosin is a medication that belongs to the class of alpha-adrenergic blockers, which relax the muscles in the prostate and bladder neck, making it easier to urinate.It also lowers blood pressure by relaxing the veins and arteries, allowing blood to flow more easily.Therefore, terazosin can cause dizziness or fainting, especially when getting up from a sitting or lying position.To prevent this, the patient should rise slowly and avoid standing for long periods or becoming overheated.

Choice B is wrong because terazosin is not a cure for benign prostatic hyperplasia (BPH), but a symptom reliever.Stopping the medication may cause the urinary problems to return or worsen.

The patient should continue taking terazosin as prescribed by the doctor, unless advised otherwise.

Choice C is wrong because decreasing fluid intake may increase the risk of dehydration, urinary tract infections, bladder stones, and kidney problems.

The patient should drink enough fluids to stay hydrated and flush out the urinary system.

Choice D is wrong because grapefruit juice may interact with terazosin and increase its blood levels, leading to more side effects such as low blood pressure, drowsiness, or headache.

The patient should avoid drinking grapefruit juice while taking terazosin, or consult the doctor before doing so.

A. Dry mouth. B. Restlessness. C. Increased salivation. D. Diarrhea.

Correct Answer is A

Explanation

Dry mouth is a common adverse effect of anticholinergic agents used to treat overactive bladder syndrome (OAB).Anticholinergic agents prevent involuntary contractions of the bladder detrusor muscle by blocking the action of acetylcholine, a neurotransmitter that stimulates the muscle.However, anticholinergics are not tissue specific, and they also affect other parts of the body where acetylcholine is involved, such as the salivary glands, the gastrointestinal tract, and the eyes.

Choice B is wrong because restlessness is not a typical side effect of anticholinergic agents.In fact, anticholinergics can cause sedation and drowsiness in some people.

Choice C is wrong because increased salivation is the opposite of what anticholinergics do.Anticholinergics reduce the secretion of saliva, causing dry mouth.

Choice D is wrong because diarrhea is also the opposite of what anticholinergics do.Anticholinergics slow down the movement of the gastrointestinal tract, causing constipation.

Some other possible adverse effects of anticholinergic agents include blurred vision, urinary retention, confusion, memory impairment, and increased risk of dementia and mortality.

Therefore, these drugs should be used with caution and under medical supervision.
