Question 1 of 5
Which of the following cytotoxic drugs is least likely to cause emesis during chemotherapy?
Correct Answer: D
Rationale: Emesis risk depends on chemotherapeutic emetogenicity. Cisplatin, dacarbazine, doxorubicin, and mustine are highly emetogenic, triggering vomiting via chemoreceptor zones. Vincristine, a vinca alkaloid, is least emetogenic, causing neuropathy instead, making it the exception. This lower risk reduces antiemetic needs, easing patient burden during treatment.
Question 2 of 5
The application of drugs for the purpose of treating diseases and treatment of suffering is known as
Correct Answer: B
Rationale: Pharmacotherapeutics applies drugs to treat diseases and alleviate suffering, combining pharmacology and therapeutic intent, a precise term. Biologics are drug types, not application. Alternative therapies use non-drug methods. Therapeutics is broader, but pharmacotherapeutics specifies drug use, aligning with the definition and clinical practice.
Question 3 of 5
The nurse plans to administer medication to the preschool child. Which approach indicates the nurse has an understanding of growth and development?
Correct Answer: D
Rationale: Preschoolers (3-5) respond to simple explanations and swift action-e.g., 'This helps you feel better,' then give-matching their short attention and trust needs. Parents often calm, not hinder, cooperation. Play aids understanding, not just verbal. Restraint may be needed if uncooperative-age doesn't rule it out. Brief rationale and quick delivery suit developmental stage, minimizing distress.
Question 4 of 5
The 8-year-old patient is receiving methylphenidate (Ritalin). The patient's mother tells the nurse that he won't eat while on his medication. What is the best response by the nurse?
Correct Answer: B
Rationale: Methylphenidate curbs appetite-giving it post-meals and adding snacks offsets weight loss, per practical management. Depression isn't indicated-appetite loss is a known effect. Appetite stimulants aren't standard. Nutritionists help long-term, not acutely. Post-meal dosing balances efficacy and nutrition, per care.
Question 5 of 5
A 27-year-old medical student has recurrent sinusitis and takes an over-the-counter agent. Unfortunately, he fell asleep while taking his final examination of the anatomy course. Which of the following agents is most likely to cause this adverse effect?
Correct Answer: D
Rationale: Sinusitis treatment often involves OTC antihistamines. Diphenhydramine , an H1 antihistamine, causes sedation, explaining the student's sleepiness during the exam. Doxycycline , an antibiotic, doesn't sedate. Doxylamine , another sedating antihistamine, is possible but less commonly linked to sinusitis OTC use. Doxazosin , an α-blocker, isn't for sinusitis. Hydroxyzine (E) sedates but is prescription-based. Diphenhydramine's widespread OTC availability and drowsiness side effect fit the scenario, impacting the student's performance.
