C. Increased urine ketones: Increased urine ketones are associated with conditions like diabetes and starvation, not specifically fluid volume deficit.
D. Decreased hematocrit: Fluid volume deficit usually results in increased hematocrit due to hemoconcentration.

A. To remove gastric acid that might cause dyspepsia B. To identify delayed gastric emptying C. To confirm the placement of the NG tube D. To determine the client's electrolyte balance

Correct Answer is B

Explanation

not to remove gastric acid but to assess tolerance to feedings.
B. To identify delayed gastric emptying: Measuring gastric residual volume helps identify delayed gastric emptying, which can indicate a risk of aspiration or intolerance to the feeding.
C. To confirm the placement of the NG tube: Tube placement should be confirmed by other means, such as pH testing or X-ray, rather than measuring residual.
D. To determine the client's electrolyte balance: Measuring gastric residual does not provide information about the client's electrolyte balance.
