Question 1 of 5
Gold salt toxicity can be reversed using which medication?
Correct Answer: B
Rationale: Dimercaprol is a chelating agent used to treat heavy metal toxicity, including gold salt toxicity. It binds to the gold ions, forming a complex that can be excreted from the body. Acetaminophen, calcium salts, and hydroxocobalamin are not used for this purpose. Prompt administration of dimercaprol is essential to prevent severe complications of gold salt toxicity.
Question 2 of 5
A 42-year-old woman has widely disseminated colon cancer. Her main symptom is pain from a spinal crush fracture, incompletely suppressed by oral morphine. She is also troubled by constipation, nausea and occasional vomiting. Which of the following is true?
Correct Answer: D
Rationale: Metastatic colon cancer with spinal pain needs palliation. Fentanyl patches cause nausea, like morphine, due to opioid effects, so that's false. Cisplatin, for other cancers, doesn't prolong survival in advanced colon cancer (FOLFOX does). Radiotherapy to the primary isn't mainstay for metastases; palliation is. Biopsy of the vertebra is unnecessary with known cancer. Intercostal nerve block targets chest pain, not spinal, but localized nerve blocks (e.g., epidural) are true options for refractory pain, making this the best fit per key.
Question 3 of 5
ACE inhibitors:
Correct Answer: D
Rationale: ACE inhibitors increase bradykinin by blocking its breakdown, not decrease it, so that's false. Hyperkalemia is more common in diabetes due to renal issues, not less, making that false. They're not absolutely contraindicated with NSAIDs, though caution applies, so that's incorrect. They decrease efferent arteriolar resistance, reducing glomerular pressure, a true statement, key in renoprotection. They don't reduce prostaglandins (NSAIDs do). This hemodynamic effect is vital in hypertension and diabetic nephropathy.
Question 4 of 5
The physician has prescribed a brand name drug for the client. The client tells the nurse that the medication is too expensive. What is the best plan by the nurse?
Correct Answer: C
Rationale: Generic drugs, bioequivalent to brand names, cost less, making substitution the best plan to address expense while maintaining therapy. Assistance programs help but delay access. Cheaper brands may not exist or differ therapeutically. Samples are unsustainable. Generics offer a practical, immediate solution, widely supported by formularies, aligning with cost-effective care.
Question 5 of 5
The nurse teaches a class about medication used during pregnancy to pregnant women. The nurse determines that additional instruction is required when a class participant makes which response?
Correct Answer: A
Rationale: Drugs harm fetuses across trimesters-first (organogenesis) is critical, but later effects (e.g., growth) occur, so this needs correction. Avoiding OTC drugs is wise-many risk harm. Teratogens cause death or defects, true. Breast milk transfers drugs, also true. First-trimester-only harm misstates risk, requiring reteaching.
