A client comes to a primary care provider's office for a follow-up on their gastroesophageal reflux disease (GERD). The provider has decided to screen the client for Barrett esophagus due to the patient struggling with symptoms for many years. The nurse should provide instruction on which diagnostic procedure?

Choice A reason: Active transport is the process of moving molecules across a cell membrane against a concentration gradient, requiring energy.

Choice B reason: Diffusion is the process of moving molecules from an area of high concentration to an area of low concentration, without using energy.

Choice C reason: Filtration is the process of moving fluid and solutes through a membrane by a pressure gradient.

Choice D reason: Osmosis is the process of moving water across a semipermeable membrane from an area of low solute concentration to an area of high solute concentration.

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.
