The primary health care provider prescribes methotrexate for a client with a new diagnosis of rheumatoid arthritis. The nurse provides health teaching about the drug. What statement by the nurse is appropriate to include about methotrexate?
It will take at least 1 to 2 weeks for the drug to help relieve your symptoms.
The drug is very expensive but there are pharmacy plans to help pay for it.
The drug can increase your risk for infection, so you should avoid crowds.
It’s OK for you to drink about 2 to 3 glasses of wine each week while taking the drug.
The Correct Answer is C
Choice A reason: Methotrexate typically takes 6–12 weeks to achieve therapeutic effects in rheumatoid arthritis by suppressing immune-mediated inflammation. Stating 1–2 weeks is inaccurate, as it underestimates the time needed for the drug to modulate immune response and reduce joint inflammation.
Choice B reason: Discussing cost and pharmacy plans is not a priority in health teaching about methotrexate’s clinical effects. While cost may be a concern, it is not relevant to the drug’s pharmacological action or patient safety education.
Choice C reason: Methotrexate is an immunosuppressant, reducing immune response to control RA inflammation. This increases infection risk, as immune cells like neutrophils are suppressed. Avoiding crowds minimizes exposure to pathogens, making this a critical and appropriate teaching point for patient safety.
Choice D reason: Alcohol consumption, even in moderation (2–3 glasses of wine weekly), is discouraged with methotrexate due to its hepatotoxic effects. Alcohol exacerbates liver damage risk, as methotrexate is metabolized by the liver, potentially leading to elevated liver enzymes or hepatotoxicity.

Correct Answer is A
Explanation
Choice A reason: The wearing-off phenomenon in Parkinson’s occurs when levodopa’s effect diminishes before the next dose, causing symptom fluctuations. This results from progressive dopamine neuron loss, reducing storage capacity, and shorter levodopa half-life, leading to rapid swings in motor control as plasma levels fluctuate.
Choice B reason: Intolerance to medications may cause side effects (e.g., nausea), but the wearing-off phenomenon is due to disease progression and levodopa’s pharmacokinetics, not patient tolerance. Symptoms return as drug levels drop, not because of inability to tolerate the dose.
Choice C reason: Medications like levodopa remain effective, but wearing-off occurs due to shorter duration of action as Parkinson’s progresses, not loss of drug efficacy. Neuron loss reduces dopamine storage, causing symptoms to re-emerge between doses, not a failure of the drug itself.
Choice D reason: The liver metabolizes levodopa minimally; carbidopa prevents peripheral breakdown. Wearing-off is due to central nervous system changes (loss of dopamine neurons), not liver dysfunction, which does not significantly alter levodopa’s pharmacokinetics in Parkinson’s disease.
Correct Answer is ["3.3"]
Explanation
Step 1 is: Convert pounds to kilograms 12 ÷ 2.2 = 5.4545 Result = 5.4545 kg
Step 2 is: Multiply by dosage per kg 5.4545 × 15 = 81.818 Result = 81.818 mg
Step 3 is: (125 ÷ 5) = 25 Result = 25 mg/mL
Step 4 is: (81.818 ÷ 25) = 3.27272 Result = 3.3 mL after rounding to the nearest tenth
