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?

Active transport

Osmosis

Filtration

Diffusion

Answer and Explanation

The Correct Answer is B

Choice A reason: Active transport is not the process that allows fluid to pass through a membrane from a dilute to a more concentrated area. Active transport is the process that moves solutes across a membrane against their concentration gradient, using energy from ATP. Active transport can create or maintain a concentration difference between two sides of a membrane.

Choice B reason: Osmosis is the process that allows fluid to pass through a membrane from a dilute to a more concentrated area. Osmosis is the movement of water across a selectively permeable membrane from an area of low solute concentration to an area of high solute concentration. Osmosis can equalize the concentration of solutes on both sides of a membrane.

Choice C reason: Filtration is not the process that allows fluid to pass through a membrane from a dilute to a more concentrated area. Filtration is the movement of fluid and solutes across a membrane due to a pressure difference between two sides of a membrane. Filtration can separate solutes from fluid based on their size and charge.

Choice D reason: Diffusion is not the process that allows fluid to pass through a membrane from a dilute to a more concentrated area. Diffusion is the movement of solutes across a membrane from an area of high solute concentration to an area of low solute concentration. Diffusion can also equalize the concentration of solutes on both sides of a membrane.

Correct Answer is B

Explanation

Choice A reason: MRI is not a diagnostic procedure for Barrett esophagus. MRI is a type of imaging test that uses magnetic fields and radio waves to create detailed pictures of the internal organs and tissues. It is mainly used to diagnose problems in the brain, spine, joints, and blood vessels.

Choice B reason: EGD is a diagnostic procedure for Barrett esophagus. EGD is a type of endoscopy that uses a flexible tube with a light and a camera to examine the esophagus, stomach, and duodenum. It can detect changes in the lining of the esophagus that may indicate Barrett esophagus, a condition where the normal squamous cells are replaced by columnar cells due to chronic acid exposure.

Choice C reason: Colonoscopy is not a diagnostic procedure for Barrett esophagus. Colonoscopy is a type of endoscopy that uses a flexible tube with a light and a camera to examine the colon and rectum. It is mainly used to screen for colorectal cancer and polyps, as well as to diagnose inflammatory bowel disease and other conditions affecting the lower gastrointestinal tract.

Choice D reason: CT scan is not a diagnostic procedure for Barrett esophagus. CT scan is a type of imaging test that uses X-rays and a computer to create cross-sectional pictures of the body. It is mainly used to diagnose problems in the chest, abdomen, pelvis, and bones.

A. Include foods high in starch and proteins B. Include foods high in fiber C. Avoid foods high in sodium D. Avoid foods high in fat

Correct Answer is D

Explanation

Choice A reason: Including foods high in starch and proteins is not a specific dietary instruction for a client who has biliary colic from chronic cholecystitis. Starch and protein intake may vary depending on the client's overall nutritional needs and preferences.

Choice B reason: Including foods high in fiber is a general dietary recommendation for most people, but it is not directly related to biliary colic or cholecystitis. Fiber helps with bowel regularity and may lower the risk of some chronic diseases, but it does not affect the production or flow of bile.

Choice C reason: Avoiding foods high in sodium is a dietary instruction for clients who have hypertension, heart failure, or kidney disease, but it is not relevant for biliary colic or cholecystitis. Sodium intake does not influence the formation or dissolution of gallstones, which are the main cause of biliary colic.

Choice D reason: Avoiding foods high in fat is a dietary instruction for clients who have biliary colic from chronic cholecystitis. Fat intake stimulates the contraction of the gallbladder, which can cause pain and inflammation if there are gallstones blocking the bile ducts. Reducing fat intake can help prevent or reduce the frequency and severity of biliary colic episodes.
