A nurse is reviewing the health record of a client who asks about using propranolol to treat hypertension.
The nurse should recognize which of the following conditions is a contraindication for taking propranolol?

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.

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.
