ATI Medical Surgical Nursing, Assessment and Care of Patients with Acid-Base Imbalances 1. In a client with less than the normal amount of bicarbonate in the blood and other extracellular fluids, wha... t response does the nurse anticipate? a. Increased risk for acidosis b. Decreased risk for acidosis c. Increased risk for alkalosis d. Decreased risk for alkalosis ANS: A Bicarbonate (H2CO3–) is a weak base with an overall negative charge. When hydrogen ions are present in slight or mild excess (mild acidosis), bicarbonate can buffer or absorb the excess hydrogen ions, reducing the hydrogen ion concentration and bringing the pH back up to normal. If the total body bicarbonate concentration is low, especially in the blood, the action of buffering or absorbing excess hydrogen ions is reduced, and the person is at increased risk for acidosis.
