Question 1 of 5
Which nursing intervention(s) should the nurse consider for the patient taking ciprofloxacin? (Select all that apply.)
Correct Answer: A
Rationale: Ciprofloxacin is a fluoroquinolone antibiotic that requires careful monitoring. Obtaining a culture before administration ensures the infection is susceptible to ciprofloxacin. Tendon pain or rupture is a serious adverse effect of fluoroquinolones, particularly in older adults or those on corticosteroids. Dairy products can interfere with the absorption of ciprofloxacin, so patients should avoid them around the time of administration. Dizziness may indicate central nervous system effects, which should be reported promptly.
Question 2 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 3 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 4 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 5 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.
