Antiparkinson drugs restore which two chemicals necessary for transmitting nerve impulses?
Acetylcholine and dopamine
Epinephrine and acetylcholine
Acetylcholine and calcium
Dopamine and epinephrine
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: Antipyretics reduce fever; Coumadin prevents clots, not fever. This misidentifies purpose, per nursing pharmacology. It’s a universal error, distinctly unrelated to anticoagulation therapy.
Choice B reason: Antibiotics fight infection; Coumadin thins blood, not bacteria. This errors in class, per nursing standards. It’s universally distinct, missing Coumadin’s anticoagulant role entirely.
Choice C reason: Coumadin (warfarin) is an oral anticoagulant, preventing clotting effectively. This matches, per nursing pharmacology. It’s universally recognized, distinctly applied for blood clot management.
Choice D reason: Anti-inflammatories reduce swelling; Coumadin targets clotting, not inflammation. This misaligns, per nursing standards. It’s universally distinct, errors in drug classification comprehensively.
Correct Answer is C
Explanation
Choice A reason: Lasix is given IV or orally, not subQ in the belly. Heparin fits this route, per nursing standards. This errors universally, distinctly missing subcutaneous administration.
Choice B reason: Digoxin is oral or IV, not subQ in the abdomen. Heparin is correct, per nursing pharmacology. This misaligns universally, distinctly unrelated to belly injections.
Choice C reason: Heparin is injected subQ in the belly, 2 inches from umbilicus, for anticoagulation. This matches, per nursing standards. It’s universally applied, distinctly effective.
Choice D reason: Phenobarbital is oral or IV, not subQ in the belly. Heparin suits this, per nursing pharmacology. This errors universally, distinctly off-target for route.
