A client with fluid volume excess is having trouble breathing and coughing. The nurse should expect the physician to order which laboratory test for this client?

Answer: 1.
1. The physician likely would order serum electrolytes to see the sodium level and renal studies, since the kidneys manage fluid and electrolyte balance.
2. Hematocrit will give the physician a sense of fluid levels, but enzymes do not reflect fluid or electrolyte levels.
3. Gallbladder studies reflect the status of the gallbladder only.
4. An MRI is a scan that determines the denseness of tissues.
