Question 1 of 5
The following drugs are commonly associated with serotonin syndrome:
Correct Answer: A
Rationale: Fluoxetine, an SSRI, is a common cause of serotonin syndrome when used alone or in combination with other serotonergic agents.
Question 2 of 5
Adalimumab (Humira) is given to a client for the treatment of rheumatoid arthritis. Which of the following side effect is associated with the medication?
Correct Answer: D
Rationale: Adalimumab, a tumor necrosis factor (TNF) inhibitor, is associated with weight gain as a potential side effect. This may occur due to fluid retention or changes in metabolism. Numbness, constipation, and urinary retention are not commonly linked to adalimumab. Weight gain is a significant consideration for patients, as it can impact their overall health and adherence to treatment. Monitoring for this side effect is important, and dietary or lifestyle interventions may be necessary to manage it effectively.
Question 3 of 5
A mother brings her 4-year-old son to the emergency department after discovering him eating her iron supplement. Which of the following should be administered to chelate the excess iron in his body?
Correct Answer: B
Rationale: Iron overdose in a child requires a specific chelator. Deferoxamine binds ferric iron, forming ferrioxamine, excreted renally. EDTA chelates calcium and lead, not iron-specific. Dimercaprol treats heavy metals like arsenic, not iron. Penicillamine is for copper (Wilson's disease). Succimer (E) targets lead. Deferoxamine's high affinity for iron makes it standard for acute toxicity, preventing organ damage (e.g., liver, heart), critical in this pediatric emergency.
Question 4 of 5
The client is receiving a very expensive medication. The client asks the nurse why the medicine is so expensive. What is the best response by the nurse?
Correct Answer: C
Rationale: High drug costs stem from research, development, and production expenses-years of trials and manufacturing-requiring companies to recover investments, a factual explanation. Insurance coverage sidesteps the question. Advertising adds cost but isn't primary. Accountability is opinion, not answer. Development costs provide a clear, neutral reason, educating the client on pharmaceutical economics.
Question 5 of 5
Which of the following is used to treat migraine headaches?
Correct Answer: B
Rationale: Beta blockers are commonly used in the treatment of migraine headaches. These medications work by blocking the action of certain chemicals that cause blood vessels to dilate. By helping to prevent blood vessel dilation and constriction, beta blockers can help reduce the frequency and severity of migraine attacks. Additionally, beta blockers are thought to interfere with the transmission of pain signals in the brain.
