When assessing a client for potential alcohol abuse problems, the nurse will seek the results of the most sensitive laboratory test for detecting the effects of chronic alcohol abuse, which is:
1. Elevated erythrocyte mean corpuscular volume (EMCV)
2. Serum glutamic-pyruvic transaminase (SGPT)
3. Lactic dehydrogenase (LDH)
4. Serum gamma-glutamyl transferase (GGT)
ANS: 4
GGT (option 4) is the most sensitive marker for recent alcohol use. EMCV (option 1) can be an indicator of long-term alcohol use. SGPT (option 2) is an indictor of hepatic problems. LDH (op-tion 3) is an indicator of cardio isoenzymes.
