Section: Questions Set B
Explanation:
(A) Diarrhea is a complication of tube feedings that can lead to dehydration. Diarrhea may be the result of hypertonic formulas that can draw fluid into the bowel. Other causes of diarrhea may be bacterial contamination, fecal impaction, medications, and low albumin. (B) A consistent weight gain of more than 0.22 kg/day (1ꢀ2 lb/day) over several days should be reported promptly. The client should be evaluated for fluid volume excess. (C) Elevating the client's head prevents reflux and thus formula from entering the airway. (D) Bacteria proliferate rapidly in enteral formulas and can cause gastroenteritis and even sepsis.

(A, C, D) This answer is a miscalculation. (B) 1 oz = 30 mL; therefore, 18 oz x.

Explanation/Reference:
Explanation:
(A) Increased CO2 will occur in both acute and chronic respiratory acidosis. (B) Hypoxia does not determine acid-base status. (C) Elevation of HCO3 is a compensatory mechanism in acidosis that occurs almost immediately, but it takes hours to show any effect and days to reach maximum compensation.
Renal disease and diuretic therapy may impair the ability of the kidneys to compensate. (D) Base excess is a nonrespiratory contributor to acid-base balance. It would increase to compensate for acidosis.

(A) Although all of these interventions are important aspects of care, weight is the most sensitive indicator of fluid balance. (B) Although monitoring intake and output is important, weight is a more accurate indicator of fluid status. (C) Urine specific gravity does not necessarily indicatefluid volume excess. (D) Edema may not be apparent, yet the client may have fluid volume excess.
