the nurse is reviewing a clients laboratory results. the nurse notes that which results support a diagnosis of dehydration? select all that apply.
rationale, strategy, reference, tip
answer options
1 increased creatinine
2 increased hemoglobin
3 increased serum sodium
4 decreased urine specific gravity
5 decreased estimated glomerular filtration rate (egfr)

Explanation:

Dehydration causes concentration of substances in the blood. Creatinine levels rise as the kidneys have less fluid to filter. Hemoglobin levels increase due to the relative loss of plasma volume. Serum sodium can increase as water loss exceeds sodium loss. A decreased eGFR occurs as the kidneys are less perfused due to low - volume state. Urine specific gravity increases in dehydration as the kidneys try to conserve water, not decrease.

Answer:

1. Increased creatinine
2. Increased hemoglobin
3. Increased serum sodium
4. Decreased estimated glomerular filtration rate (eGFR)
