Question 1 of 5
During pharmacology class, the student nurse asks the nursing instructor how students will ever learn about the individual antibiotic drugs since there are so many. What is the best response by the nursing instructor?
Correct Answer: D
Rationale: Learning a representative (prototype) drug from each antibiotic class simplifies understanding by focusing on shared traits-mechanisms, effects, and side effects-reducing the burden of memorizing every drug. Mnemonics aid recall but don't teach concepts. Flow charts organize but lack depth. Categorizing is broad, while prototypes offer a practical, foundational approach, widely used in pharmacology education for mastery.
Question 2 of 5
The patient receives imipramine (Tofranil) as treatment for depression. He is admitted to the emergency department following an intentional overdose of this medication. What will the priority assessment by the nurse include?
Correct Answer: A
Rationale: Imipramine, a TCA, in overdose risks cardiac toxicity-arrhythmias (e.g., QRS widening)-per toxicology, making heart status priority. Liver and renal function matter but are secondary-cardiac collapse kills faster. Neurological signs (e.g., seizures) follow but heart trumps. Cardiac focus saves lives, per protocol.
Question 3 of 5
A 62-year-old man with Parkinson's disease on levodopa and carbidopa presents to his primary care physician for follow-up. He is following his prescribed course of medications. He is stable in terms of his motor function but recently has begun to have visual and auditory hallucinations. What is the most likely explanation for these findings?
Correct Answer: A
Rationale: Hallucinations in a Parkinson's patient on levodopa/carbidopa suggest a medication-related issue. Drug toxicity is correct-levodopa increases dopamine, and excess in non-motor areas (e.g., mesolimbic) can cause hallucinations, especially with long-term use or dose accumulation. Overactivity at basal ganglia improves motor symptoms, not hallucinations. Subtherapeutic dosing would worsen motor control, not cause this. Dementia or infection (E) could contribute, but hallucinations align more with levodopa's known side effect profile. Carbidopa reduces peripheral effects, but central dopamine excess remains possible, making toxicity the likely culprit in this stable motor context.
Question 4 of 5
A 37-year-old woman is brought to the emergency department by a friend after consuming an entire month's supply of amitriptyline. She is tachycardic, drowsy, nauseous, and has a headache. Which of the following could the physician administer to help this patient?
Correct Answer: A
Rationale: Amitriptyline overdose (TCA) causes anticholinergic and cardiac toxicity. Bicarbonate corrects acidosis and stabilizes sodium channels, reducing arrhythmias. Dimercaprol , Methylene blue , and Vitamin K (E) are irrelevant. Naloxone treats opioids. Bicarbonate's role in TCA overdose is critical for this presentation.
Question 5 of 5
A 38-year-old man who is a chronic coffee drinker for 20 years drinks approximately seven cups of coffee per day. He suddenly decides to stop drinking coffee. Which of the following effects may he exhibit?
Correct Answer: A
Rationale: Chronic high-dose caffeine cessation causes withdrawal. Lethargy -reflects reduced adenosine blockade, leading to fatigue. Migraine , nausea , and vomiting (E) may occur, but lethargy is most common. Tinnitus isn't typical. His 20-year habit predicts this CNS depression.
