Which of the following is a drug that produces vasodilation, improves cardiac output, and lowers blood pressure?

Choice A reason: Back-of-tongue placement eases swallowing; it’s standard practice. Last med isn’t a rule. This fits nursing pharmacology standards. It’s universally distinct, correct.

Choice B reason: Water moistens mouth, aiding swallowing; it’s routine always. Last med isn’t required. This aligns with nursing standards. It’s universally distinct, proper.

Choice C reason: Importance order isn’t a principle; other steps are standard. This is the exception per nursing pharmacology. It’s universally distinct, not applicable.

Choice D reason: Staying ensures meds are taken; it’s essential always. Last med isn’t a principle. This fits nursing standards. It’s universally distinct, safety-focused.

Choice A reason: Antiparkinson drugs, like levodopa, restore dopamine and balance acetylcholine, vital for nerve signaling in Parkinson’s disease. This corrects motor deficits, aligning with nursing pharmacology. These neurotransmitters are universally targeted, distinctly addressing the disease’s chemical imbalance for effective impulse transmission.

Choice B reason: Epinephrine isn’t a primary Parkinson’s target; dopamine and acetylcholine are key. This misidentifies neurotransmitters involved in motor control, per nursing standards. Epinephrine relates to stress, not nerve restoration, making it a distinct error universally in pharmacology.

Choice C reason: Calcium supports nerve function but isn’t restored by antiparkinson drugs. Acetylcholine and dopamine are specific targets, per nursing knowledge. This choice errors by including calcium, missing the disease’s focus, a universal misunderstanding in pharmacology application distinctly.

Choice D reason: Epinephrine doesn’t treat Parkinson’s; dopamine and acetylcholine do. This pairing misaligns with antiparkinson goals, per nursing pharmacology. It overlooks dopamine’s role in motor control, a distinct error universally recognized in managing nerve impulse transmission effectively.
