A nurse is reviewing a client's laboratory results for effectiveness of total parenteral nutrition (TPN). Which of the following laboratory values is the best indicator for the nurse to monitor for short-term effectiveness of the TPN?
Hemoglobin
Transferrin
Prealbumin
Total albumin
The Correct Answer is C
A. Hemoglobin levels primarily reflect the oxygen-carrying capacity of red blood cells and are not specific to nutritional status.
B. Transferrin levels reflect iron-binding capacity and may be influenced by factors other than nutrition.
C. Prealbumin levels have a shorter half-life compared to total albumin and can provide a more immediate assessment of nutritional status and the effectiveness of TPN in the short term.
D. Total albumin levels reflect longer-term protein status and may not change significantly in the short term with TPN administration.

Correct Answer is A
Explanation
A. Spironolactone is a potassium-sparing diuretic that can cause hyperkalemia, which can lead to symptoms such as increased thirst. Notifying the provider of increased thirst can help monitor for potential electrolyte imbalances.
B. Consuming foods high in potassium can exacerbate hyperkalemia, which is a potential side effect of spironolactone. Clients prescribed spironolactone are typically advised to avoid potassium-rich foods.
C. Using a salt substitute to season foods can increase sodium intake, which may counteract the effects of spironolactone and increase the risk of fluid retention and hypertension.
D. Taking spironolactone at bedtime is not typically recommended. It is usually taken in the morning to avoid disrupting sleep due to increased urination.
