Fluid and electrolyte balance is maintained through the process of fluid and solutes moving in and out of cells. What specific process allows fluid to pass through a membrane from a dilute to a more concentrated area?

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: The upper right quadrant is not the correct location for McBurney's point. This quadrant contains the liver, gallbladder, right kidney, and part of the colon. Pain in this area may indicate problems with these organs, such as hepatitis, gallstones, or kidney infection.

Choice B reason: The upper left quadrant is not the correct location for McBurney's point. This quadrant contains the stomach, spleen, left kidney, and part of the colon. Pain in this area may indicate problems with these organs, such as gastritis, splenomegaly, or kidney stones.

Choice C reason: The lower right quadrant is the correct location for McBurney's point. This quadrant contains the appendix, right ovary, and right fallopian tube. McBurney's point is a point on the abdomen that is one-third of the distance from the right anterior superior iliac spine to the umbilicus. Pain in this area may indicate appendicitis, ovarian cyst, or ectopic pregnancy.

Choice D reason: The lower left quadrant is not the correct location for McBurney's point. This quadrant contains the sigmoid colon, left ovary, and left fallopian tube. Pain in this area may indicate problems with these organs, such as diverticulitis, ovarian torsion, or pelvic inflammatory disease.
