A client has been prescribed an alpha-adrenergic, terazosin for their benign prostatic hypertrophy.
The nurse plans to include which of the following in the client teaching?
Rise slowly.
Stop taking when symptoms have subsided.
Decrease fluid intake.
Take this medication with grapefruit juice.
The Correct Answer is A
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.

Correct Answer is D
Explanation
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.
Correct Answer is C
Explanation
LDL cholesterol is sometimes called “bad” cholesterol because it can build up on the walls of the blood vessels and cause health problems, such as heart disease and stroke.High levels of LDL cholesterol raise your risk for cardiovascular disease. Therefore, decreasing LDL cholesterol levels can lower your risk and improve your health.
Choice A is wrong because increasing LDL cholesterol levels would have the opposite effect of decreasing them.It would increase your risk for cardiovascular disease and plaque buildup in your arteries.
Choice B is wrong because increasing HDL cholesterol levels is not enough to decrease the risk of cardiovascular disease.HDL cholesterol is sometimes called “good” cholesterol because it can move LDL cholesterol from the blood to the liver, where it is broken down and removed from the body.
However, HDL cholesterol levels alone are not a good indicator of your cardiovascular health.You also need to consider your total cholesterol, LDL cholesterol and triglyceride levels.
Choice D is wrong because decreasing HDL cholesterol levels would also increase your risk for cardiovascular disease.HDL cholesterol helps to lower LDL cholesterol levels and protect your blood vessels from plaque buildup.
Therefore, decreasing HDL cholesterol levels would reduce this protective effect and make you more vulnerable to heart disease and stroke.
The ideal ranges for cholesterol levels are as follows:
• Total cholesterol: below 200 mg/dL
• LDL cholesterol: less than 100 mg/dL
• HDL cholesterol: above 40 mg/dL for men and above 50 mg/dL for women
You can lower your LDL cholesterol levels and increase your HDL cholesterol levels by making healthy lifestyle changes, such as eating a balanced diet, exercising regularly, quitting smoking, managing stress and taking medication if prescribed by your doctor.
