If you are unsure about a dosage, potential side effects, or contraindications, which resource should you consult?

• A. A drug reference book, pharmacist, or an acceptable technology resource (e.g., Micromedex, Epocrates).
• B. A social media post from a patient forum.
• C. A colleague who is not trained in pharmacology without checking the order.
• D. The manufacturer's advertisement.

Answer: (A)

When you’re unsure about dosage, potential side effects, or contraindications, rely on authoritative, evidence-based drug information resources. A drug reference book or an acceptable technology resource like Micromedex or Epocrates provides current dosing guidance, documented adverse effects, known interactions, and contraindications, and a pharmacist can help interpret this information in the context of the patient’s order. These sources are maintained by experts and updated regularly to reflect new safety data and labeling changes, which helps prevent dosing errors and missed risks.

Other sources don’t offer the same level of reliability. Social media posts are anecdotal and not validated for clinical decision-making. A colleague who isn’t trained in pharmacology and hasn’t checked the order may not have access to complete safety data. Manufacturer advertisements are marketing materials that may emphasize benefits while downplaying risks, making them inappropriate for clinical decisions.
