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

PT stands for prothrombin time, which is a measure of how long it takes the blood to clot. INR stands for international normalized ratio, which is a standardized way of reporting the PT result. Warfarin is a blood thinner that works by slowing down the clotting process.Therefore, people who take warfarin need to have their PT/INR monitored regularly to make sure they are getting the right dose and not bleeding too much or too little.

Choice A is wrong because PTT stands for partial thromboplastin time, which is another measure of blood clotting that is not affected by warfarin.PTT is used to monitor heparin, another type of blood thinner.

Choice C is wrong because CBC stands for complete blood count, which is a test that measures the number and types of cells in the blood, such as red blood cells, white blood cells and platelets.CBC can show if there is anemia, infection or bleeding, but it does not measure the effect of warfarin on clotting.

Choice D is wrong because LFTs stand for liver function tests, which are a group of tests that check how well the liver is working.

LFTs can show if there is liver damage or disease, which can affect how warfarin is metabolized and cleared from the body.However, LFTs do not directly measure the effect of warfarin on clotting.

The normal range for PT/INR varies depending on the laboratory and the reason for taking warfarin.

Generally, the normal range for PT is 10 to 13 seconds, and the normal range for INR is 1.1 or below for healthy people.For people taking warfarin, the target INR range depends on their condition and risk factors, but it is usually between 2.0 and 3.0.

Diuretics are medicines that help the kidneys get rid of excess water and salt, which can ease the symptoms of heart failure, such as breathlessness and swelling.However, diuretics may also lower the blood pressure by reducing the blood volume and the cardiac output. This can cause symptoms such as dizziness, fatigue, or fainting.Hypotension is defined as a systolic blood pressure lower than 90 mmHg or a diastolic blood pressure lower than 60 mmHg.

Choice A is wrong because fluid retention is the opposite of what diuretics do. Diuretics increase the urine output and decrease the fluid accumulation in the body.

Choice C is wrong because hyperglycemia is not a common side effect of diuretics. Hyperglycemia is a condition where the blood sugar level is too high.Diuretics may affect the blood sugar level in some cases, but usually not significantly.

Choice D is wrong because diarrhea is not a typical side effect of diuretics.

Diarrhea is a condition where the stool is loose and watery.Diuretics may cause some gastrointestinal discomfort, such as nausea or cramps, but not diarrhea.

Normal ranges for blood pressure are 120/80 mmHg for systolic/diastolic in healthy adults, and 140/90 mmHg or higher for hypertension.Normal ranges for blood sugar are 70-100 mg/dL for fasting glucose, and less than 140 mg/dL for postprandial glucose.
