A common adverse effect from phenazopyridine hydrochloride (Pyridium) administration for UTI that the nurse should teach the patient is that Pyridium:

Nitroglycerin transdermal patches are used to prevent episodes of angina (chest pain) in people who have coronary artery disease (narrowing of the blood vessels that supply blood to the heart).Nitroglycerin is a vasodilator that works by relaxing the blood vessels so that the heart does not need to work as hard and therefore does not need as much oxygen.However, if nitroglycerin is used continuously, the body may develop tolerance to its effects, meaning that it will not work as well to prevent angina attacks.Therefore, it is important to remove the patch at bedtime and apply a new one in the morning, leaving a 10-12 hour nitrate-free interval.This way, the body can restore its sensitivity to nitroglycerin and avoid angina episodes during the day.

Choice A is wrong because allergic response is not a common reason to remove the patch at night.Although some people may experience skin irritation or rash from the patch, this is usually mild and does not require discontinuation of the medication.If the skin reaction is severe or bothersome, the patch can be applied to a different area of the skin or switched to another form of nitroglycerin.

Choice C is wrong because overdose is unlikely to occur from using the patch as prescribed.Nitroglycerin patches come in doses ranging from 0.1 milligrams per hour to 0.8 mg/hr, and should be placed on clean, dry, and hairless skin for 12-14 hours and removed for 10-12 hours.If a patch loosens or falls off, it should be replaced with a fresh one.Overdose symptoms may include severe headache, dizziness, blurred vision, nausea, vomiting, sweating, chest pain, fast or irregular heartbeat, difficulty breathing, fainting, or seizures.If these occur, the patch should be removed immediately and medical attention should be sought.

Choice D is wrong because management of BPH (benign prostatic hyperplasia) is not related to nitroglycerin use.

BPH is a condition

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.
