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 B
Explanation
Class IV antidysrhythmics or calcium channel blockers have the action ofdecreasing the flow of calcium ionsinto the cardiac and vascular smooth muscle cells, thusdecreasing heart rate and contractions.
This leads to vasodilation and myocardial depression, which can help control arrhythmias, hypertension and angina.
Choice A is wrong because calcium channel blockers do not increase blood vessel spasm, but rather relax them by inhibiting the calcium influx that causes contraction.
Choice C is wrong because calcium channel blockers do not promote platelet aggregation, but rather inhibit it by interfering with the calcium-dependent binding of fibrinogen to platelets.
Choice D is wrong because calcium channel blockers do not enhance sympathetic nervous system activity, but rather counteract it by reducing the cardiac output and peripheral resistance.
Some normal ranges for reference are:
• Heart rate: 60-100 beats per minute
• Blood pressure: 120/80 mmHg
• Calcium: 8.5-10.5 mg/dL
Correct Answer is D
Explanation
Angiotensin receptor blockers (ARBs) are a class of drugs that block the action of angiotensin II, a hormone that causes blood vessels to constrict and raise blood pressure. Examples of ARBs include losartan, valsartan, candesartan, and irbesartan.ARBs are used to treat hypertension, heart failure, and chronic kidney disease.
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.
Examples of ACE inhibitors include lisinopril, enalapril, ramipril, and captopril.ACE inhibitors are used to treat hypertension, heart failure, and chronic kidney disease.
