In evaluating a 21-year-old patient with fatigue and missing labs, which priority area should the nurse assess to help avoid misdiagnosis before referring to the PCP?

• A. Medication list from home
• B. Sleep habits
• C. Recent losses experienced
• D. Relationship status

Answer: (A)

Understanding how current medications and supplements can influence symptoms and lab results is essential when evaluating fatigue. A complete medication list from home helps reveal drugs that could cause fatigue as a side effect or alter lab values, which can lead to a misdiagnosis if not identified before PCP referral. By performing medication reconciliation, the nurse can rule out a drug-related cause, anticipate interactions, and ensure that any missing labs are interpreted in the correct context. Other factors like sleep habits or psychosocial issues are important for overall care, but they don’t address the immediate risk of misinterpreting findings as effectively as knowing the home medication list.
