Renal NCLEX Questions 3 questions with correct answers

Dialysis allows for the exchange of particles across a semipermeable membrane by which of the following actions? 1. Osmosis and diffusion 2. Passage of fluid toward a solution with a lower solute concentration 3. Allowing the passage of blood cells and protein molecules through it. 4. Passage of solute particles toward a solution with a higher concentration. - Answer Answer: 1. Osmosis allows for the removal of fluid from the blood by allowing it to pass through the semipermeable membrane to an area of high concentrate (dialysate), and diffusion allows for passage of particles (electrolytes, urea, and creatinine) from an area of higher concentration to an area of lower concentration. Fluid passes to an area with a higher solute concentration. The pores of a semipermeable membrane are small, thus preventing the flow of blood cells and protein molecules through it. A client is diagnosed with chronic renal failure and told she must start hemodialysis. Client teaching would include which of the following instructions? 1. Follow a high potassium diet 2. Strictly follow the hemodialysis schedule 3. There will be a few changes in your lifestyle. 4. Use alcohol on the skin and clean it due to integumentary changes. - Answer Answer: 2. To prevent life-threatening complications, the client must follow the dialysis schedule. Alcohol would further dry the client's skin more than it already is. The client should follow a low-potassium diet because potassium levels increase in chronic renal failure. The client should know hemodialysis is time-consuming and will definitely cause a change in current lifestyle.
