In a clinical practice guideline for a patient with terminal cancer, what is the key aim?

• A. Assist the patient with questions to ask the nurse about the cause of cancer
• B. Show the nurse what to do for the patient with a terminal illness
• C. Encourage best practice, eliminate errors and reduce unjustified practice variations
• D. Reduce waste of resources, assist in telling your patient what is going to happen and eliminate errors

Answer: (C)

Clinical practice guidelines aim to standardize care by applying the best available evidence to improve quality and safety. For terminal cancer, the key aim is to encourage best practice, eliminate errors, and reduce unjustified variation in care across clinicians and settings. This ensures that symptom management, timely palliative care involvement, and goals-of-care discussions are guided by evidence rather than individual habits. The other options miss this broader purpose: guidelines aren’t about teaching patients to ask about cancer causation or prescribing every nurse action, and while they relate to resource use and communication, their central function is standardizing care to reduce errors and variation.
