If your patient has a higher than normal pH (alkalosis), you would expect to also see:

Choice A reason: Producing phosphate buffers is not the main function of the kidneys in response to acid-base disturbances. Phosphate buffers are mainly found in the intracellular fluid and the urine, where they help to maintain the pH by binding or releasing hydrogen ions.

Choice B reason: Adjusting PaCO2 levels is not the function of the kidneys, but rather the function of the lungs in response to acid-base disturbances. The lungs regulate the PaCO2 levels by increasing or decreasing the rate and depth of respiration, which affects the amount of carbon dioxide exhaled.

Choice C reason: Producing protein buffers is not the function of the kidneys, but rather the function of the cells and the plasma in response to acid-base disturbances. Protein buffers are the most abundant and versatile buffers in the body, as they can act as acids or bases by donating or accepting hydrogen ions.

Choice D reason: Excreting or reabsorbing hydrogen or bicarbonate is the main function of the kidneys in response to acid-base disturbances. The kidneys regulate the HCO3- levels by either reabsorbing it from the filtrate or generating it from carbon dioxide and water. The kidneys also regulate the hydrogen ion levels by either excreting it into the urine or exchanging it for sodium ions.

Choice A reason: The client with an ileostomy is at risk for fluid volume deficit because an ileostomy is a surgical opening in the ileum, the last part of the small intestine, that allows the drainage of intestinal contents. This can result in a loss of fluids and electrolytes, especially sodium and potassium, which can lead to dehydration and hypovolemia.

Choice B reason: The client with cirrhosis is not at risk for fluid volume deficit, but rather fluid volume excess. Cirrhosis is a chronic liver disease that causes scarring and impaired liver function. This can lead to portal hypertension, which is an increase in the pressure in the portal vein that carries blood from the digestive organs to the liver. Portal hypertension can cause ascites, which is the accumulation of fluid in the abdominal cavity, and edema, which is the swelling of the tissues due to fluid retention.

Choice C reason: The client with heart failure is not at risk for fluid volume deficit, but rather fluid volume excess. Heart failure is a condition where the heart is unable to pump enough blood to meet the body's needs. This can lead to congestion of the blood vessels, which can cause pulmonary edema, which is the accumulation of fluid in the lungs, and peripheral edema, which is the swelling of the extremities due to fluid retention.

Choice D reason: The client with decreased renal function is not at risk for fluid volume deficit, but rather fluid volume excess. Decreased renal function is a condition where the kidneys are unable to filter the blood and remove excess fluids and wastes. This can lead to oliguria, which is a decrease in urine output, and anuria, which is the absence of urine output. This can cause fluid overload, which can affect the heart and the lungs.
