Question 1 of 5
The nurse is caring for a patient who is taking warfarin. The nurse notes the presence of gross hematuria and large areas of bruising on the patient's body. The nurse notifies the health care prescriber and anticipates what medication will be ordered?
Correct Answer: C
Rationale: Gross hematuria and bruising are signs of excessive anticoagulation, likely due to warfarin. Phytonadione (Vitamin K) is the antidote for warfarin toxicity and will be ordered to reverse its effects. Heparin sulfate (A) and protamine sulfate (B) are used for heparin reversal, and potassium supplements (D) are unrelated to warfarin toxicity.
Question 2 of 5
A female client who has a history of seizures went to a healthcare facility to ask the nurse regarding the use of birth control pills while on phenytoin therapy. The nurse correctly states to the client that:
Correct Answer: A
Rationale: Phenytoin induces liver enzymes that increase the metabolism of oral contraceptives, reducing their effectiveness. This increases the risk of unintended pregnancy. Pregnancy is not prohibited, but effective contraception is essential. Discontinuing phenytoin is not recommended without medical advice. Therefore, the nurse should inform the client about the decreased effectiveness of birth control pills.
Question 3 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 4 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 5 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.
