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
Alpha 1 adrenergic blocking agents have a vasodilating effect and can be used for the management of hypertension.They work by preventing the hormone norepinephrine from tightening the muscles in the walls of smaller arteries and veins, thus lowering the blood pressure.Some examples of alpha 1 blockers are doxazosin, prazosin, and terazosin.
Choice A is wrong because alpha 3 adrenergic blockers do not exist.There are only two subtypes of alpha receptors: alpha 1 and alpha 2.
Choice B is wrong because alpha 2 adrenergic antagonists are not used for hypertension.They are used for conditions like attention deficit hyperactivity disorder (ADHD) and opioid withdrawal.Alpha 2 antagonists block the negative feedback mechanism of norepinephrine release, thus increasing the amount of norepinephrine in the blood and raising the blood pressure.
Choice C is wrong because alpha 1 adrenergic agonists have the opposite effect of alpha 1 blockers.They stimulate the alpha 1 receptors and cause vasoconstriction, which increases the blood pressure.Alpha 1 agonists are used for conditions like nasal congestion and hypotension.
Correct Answer is C
Explanation
Urecholine is the brand name of bethanechol, a drug that belongs to the class of cholinergics, genitourinary.
Choice A is wrong because adrenergic drugs are those that activate the sympathetic nervous system, which is responsible for the fight-or-flight response.Adrenergic drugs can cause relaxation of the bladder and urinary retention, not contraction and emptying.
Choice B is wrong because anticholinergic drugs are those that block the action of acetylcholine, a neurotransmitter that mediates the parasympathetic nervous system, which is responsible for the rest-and-digest response.Anticholinergic drugs can also cause relaxation of the bladder and urinary retention, not contraction and emptying.
Choice D is wrong because adrenergic blockers are those that inhibit the action of adrenergic receptors, which are activated by adrenergic drugs or by the natural neurotransmitters norepinephrine and epinephrine.Adrenergic blockers can have various effects on the bladder depending on the type and location of the receptors they block, but they are not used to treat urinary retention.
