Lena Mason, who has diabetes, is admitted in a stuporous condition. Her blood gases show a pH of 7.33, PaCO2 of 40 mm Hg, and HCO3- of 20 mEq/L. What type of acid-base imbalance does this patient have?

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.

Choice A reason: For an average adult, the total intake should be approximately equal to the total output every day¹². Therefore, if the patient's total output is 2200 mL, the total intake should also be around 2200 mL.

Choice B reason: 3000 mL is more than the recommended daily fluid intake for an average adult, which is about 2500 mL³. If the patient's intake is higher than their output, they may develop fluid overload or edema.

Choice C reason: 3800 mL is much more than the recommended daily fluid intake for an average adult, which is about 2500 mL³. If the patient's intake is higher than their output, they may develop fluid overload or edema.

Choice D reason: 2400 mL is slightly less than the recommended daily fluid intake for an average adult, which is about 2500 mL³. However, if the patient's intake is lower than their output, they may develop dehydration or electrolyte imbalance.
