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 D

Explanation

Choice A reason: Dexamethasone, a steroid, acts slowly, not fast for emergencies. Epinephrine relieves bronchospasm rapidly. This choice errors per nursing standards. It’s universally distinct as unsuitable for acute COPD bronchospasm relief.

Choice B reason: Zafirlukast prevents asthma, not acute bronchospasm; it’s slow-acting. Epinephrine works instantly. This choice misaligns with nursing pharmacology. It’s universally distinct, lacking emergency speed required.

Choice C reason: Oxtriphylline, a bronchodilator, is gradual, not fast-acting. Epinephrine suits emergencies better. This choice errors per nursing standards. It’s universally distinct, ineffective for acute bronchospasm relief.

Choice D reason: Epinephrine dilates bronchi fast, ideal for acute bronchospasm in COPD. It aligns with nursing pharmacology standards. This is universally applied, distinctly effective in emergency respiratory situations.

A. This frequently occurs in some drugs and is not significant B. The drug must not be given and should be returned to the pharmacy in exchange for a fresh supply C. Only the pharmacist is responsible for the medications kept in the patient’s drug drawer and he/she must be the one to remove it D. The drug may be given, but changes in appearance should be reported to the pharmacy

Correct Answer is B

Explanation

Choice A reason: Changes signal potential instability, not normal variation; returning is safer. This errors, per nursing pharmacology. It’s universally distinct, risking potency loss in administration.

Choice B reason: Altered color, consistency, or odor suggests degradation; returning ensures safety. This aligns with nursing standards. It’s universally applied, distinctly protecting patients from ineffective drugs.

Choice C reason: Nurses assess drugs, not just pharmacists; returning is nurse-initiated. This misplaces responsibility, per nursing pharmacology. It’s universally distinct, errors in duty allocation.

Choice D reason: Giving altered drugs risks harm; reporting alone isn’t enough. Returning is safer, per nursing standards. This fails universally, distinctly compromising medication safety.
