A physician orders an isotonic IV solution for a client. Which solution should the nurse plan to administer?

Choice A reason: An antipyretic medication is not the best answer because it does not address the client's low urine output. An antipyretic medication is a drug that lowers the body temperature by reducing the production of heat or increasing the loss of heat. It may help the client feel more comfortable, but it does not improve the kidney function or prevent dehydration.

Choice B reason: A diuretic medication is not the best answer because it may worsen the client's low urine output. A diuretic medication is a drug that increases the excretion of water and electrolytes by the kidneys. It may lower the blood pressure and reduce the fluid overload, but it may also cause dehydration, electrolyte imbalance, and kidney damage.

Choice C reason: A blood culture is not the best answer because it does not address the client's low urine output. A blood culture is a laboratory test that detects the presence of bacteria or other microorganisms in the blood. It may help identify the cause of the fever and guide the antibiotic therapy, but it does not improve the kidney function or prevent dehydration.

Choice D reason: A fluid bolus is the best answer because it may improve the client's low urine output. A fluid bolus is a rapid infusion of a large volume of fluid, usually isotonic saline or lactated Ringer's solution. It may increase the blood volume and pressure, improve the tissue perfusion, and stimulate the urine production. It may also help lower the fever by diluting the pyrogens and increasing the heat loss.

Choice A reason: Pale yellow is the normal color of urine, indicating adequate hydration and no bilirubin in the urine. Bilirubin is a pigment that is produced when red blood cells are broken down. It is normally excreted in the bile, but if the bile duct is obstructed, it can accumulate in the blood and urine, causing jaundice and dark urine.

Choice B reason: Red urine can indicate blood in the urine, which can be caused by various conditions such as urinary tract infection, kidney stones, trauma, or cancer. It is not related to bile duct obstruction or cholecystitis.

Choice C reason: Greenish-brown urine can indicate bilirubin in the urine, which can be caused by bile duct obstruction or liver disease. It is a sign of cholestasis, which is a reduced or stopped flow of bile. The nurse should monitor the client for other signs of cholestasis such as jaundice, clay-colored stools, pruritus, and abdominal pain.

Choice D reason: Dark and concentrated urine can indicate dehydration, which can be caused by various factors such as fluid loss, fever, vomiting, or diarrhea. It is not related to bile duct obstruction or cholecystitis.
