A nurse is caring for a client who is postoperative following a bowel surgery and has an NG tube connected to low intermittent suction. Which of the following assessment findings should indicate to the nurse that the NG tube might not be functioning properly?

A. "Wearing an underwire bra between feedings" can compress the breast tissue, potentially leading to milk stasis and increasing the risk of mastitis.

B. "Covering your breasts immediately after feedings" can trap moisture and warmth, creating an environment conducive to bacterial growth and increasing the risk of mastitis.

C. "Applying cold compresses to your breasts before feedings" may provide temporary relief for discomfort, but it is not a primary preventive measure for mastitis.

D. "Trying to have your baby empty your breasts with each feeding" helps ensure thorough milk removal, which can prevent milk stasis and decrease the risk of mastitis. This is the correct choice.

A. Decreased serum osmolarity: Fluid volume deficit typically leads to an increase in serum osmolarity due to concentration of solutes in the blood, not a decrease.

B. Decreased hematocrit: Dehydration causes hemoconcentration, leading to an increase in hematocrit, not a decrease.

C. Elevated blood urea nitrogen (BUN): Dehydration results in decreased renal perfusion and concentration of urea in the blood, leading to elevated BUN levels.

D. Lower urine specific gravity: Dehydration causes increased urine concentration, resulting in higher urine specific gravity, not lower.
