Final answer:
The most appropriate nursing diagnosis for a client with a serum albumin of 2.8 g/dL and serum pre-albumin of 17 is 'Imbalanced Nutrition: Less Than Body Requirements,' indicating a possible issue with malnutrition.
Step-by-step explanation:
For a client who has a serum albumin of 2.8 g/dL and serum pre-albumin of 17, the appropriate nursing diagnosis is B) Imbalanced Nutrition: Less Than Body Requirements. Albumin is the most abundant plasma protein and plays a critical role in maintaining osmotic pressure which helps to keep fluid within the bloodstream. Decreased serum albumin levels, as we see in this case, often indicate malnutrition or the body's inability to absorb and utilize nutrients efficiently. Furthermore, since albumin is responsible for the transport of many substances including hormones, drugs, and fatty acids, a reduced level can detract substantially from overall well-being.
Other nursing diagnoses listed may also be relevant depending upon the client's full presentation, but given the specific lab values of lowered albumin and pre-albumin, the diagnosis that directly relates to these lab findings is Imbalanced Nutrition: Less Than Body Requirements.
