Antiparkinson drugs restore which two chemicals necessary for transmitting nerve impulses?

Acetylcholine and dopamine

Epinephrine and acetylcholine

Acetylcholine and calcium

Dopamine and epinephrine

Answer and Explanation

The Correct Answer is A

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.

Correct Answer is C

Explanation

Choice A reason: Sedatives induce calm, not lower blood pressure directly. Vasodilators target BP reduction specifically. This choice errors per nursing pharmacology standards. It’s universally distinct as unrelated to BP management, lacking the required mechanism.

Choice B reason: Intermediate-acting defines duration, not BP-lowering action. Vasodilators reduce pressure effectively. This choice misaligns with nursing pharmacology definitions. It’s universally distinct, missing the functional role specified in the question.

Choice C reason: Vasodilators, like nitroglycerin, widen vessels, lowering BP efficiently. This matches nursing pharmacology standards precisely. It’s universally recognized, distinctly applied in practice for hypertension or angina management effectively.

Choice D reason: Vasoconstrictors raise BP, opposite of lowering it. Vasodilators fit the description accurately. This choice errors per nursing pharmacology principles. It’s universally distinct, contradicting the question’s intent entirely.

A. "It can take several weeks before you feel like the medication is helping." B. "You should take the medication when needed for obsessive urges." C. "Take the medication just before bedtime to promote sleep." D. "Monitor yourself for weight gain while taking this medication."

Correct Answer is A

Explanation

Choice A reason: Paroxetine, an SSRI, needs weeks to ease OCD symptoms. This fits nursing pharmacology education standards. It’s universally distinct, critical for patient expectations.

Choice B reason: PRN isn’t for SSRIs; daily use treats OCD effectively. This errors per nursing standards. It’s universally distinct, misrepresenting administration schedule.

Choice C reason: Bedtime isn’t key; paroxetine isn’t for sleep primarily. This choice misaligns with nursing pharmacology. It’s universally distinct, off OCD focus.

Choice D reason: Weight gain is secondary; delayed effect is primary teaching. This errors per nursing standards. It’s universally distinct, missing main point.
