1. What is the homeostatic cellular transport mechanism that moves water from a hypotonic to a hypertonic fluid space?

• A. Filtration
• B. Diffusion
• C. Osmosis
• D. Active transport

Correct answer: C

Rationale: The correct answer is C: Osmosis. Osmosis is the homeostatic cellular transport mechanism that moves water from a hypotonic to a hypertonic fluid space to maintain cellular balance. In osmosis, water moves across a semi-permeable membrane from an area of low solute concentration (hypotonic) to an area of high solute concentration (hypertonic). This process helps regulate the water content inside cells. Choices A, B, and D are incorrect. Filtration involves the movement of solutes and solvents through a membrane due to a pressure difference, diffusion is the movement of solutes from an area of high concentration to low concentration, and active transport requires energy to move substances against their concentration gradient.

2. A client admitted to the hospital with advanced liver failure related to chronic alcoholism is exhibiting ascites and edema. Which pathophysiological mechanisms should the nurse identify as responsible for the third spacing symptoms? (Select all that apply.)

• A. Portal hypertension.
• B. Sodium and water retention.
• C. Decreased serum albumin.
• D. All of the above

Correct answer: D

Rationale: In advanced liver failure related to chronic alcoholism, ascites and edema occur due to multiple pathophysiological mechanisms. Portal hypertension contributes to the development of ascites by increasing pressure in the portal venous system. Sodium and water retention exacerbate fluid accumulation in the third space. Decreased serum albumin levels lead to reduced oncotic pressure, contributing to the movement of fluid into the interstitial spaces. Abnormal protein metabolism further disrupts fluid balance. Therefore, all of the options (A, B, and C) are correct in this scenario, making choice D the correct answer. Choices A, B, and C alone do not fully explain the comprehensive pathophysiological mechanisms involved in the development of ascites and edema in this clinical context.

3. The nurse is assessing a client with a suspected diagnosis of deep vein thrombosis (DVT). Which clinical sign is most indicative of DVT?

• A. Redness and warmth over the affected area
• B. Decreased peripheral pulses
• C. Cyanosis of the toes
• D. Muscle cramps in the calf

Correct answer: A

Rationale: Corrected Rationale: Redness and warmth over the affected area are classic signs of inflammation, which commonly occur in deep vein thrombosis (DVT) due to the obstruction of blood flow. These symptoms result from the body's inflammatory response to the blood clot. Choices B, C, and D are less indicative of DVT. Decreased peripheral pulses may occur in arterial insufficiency rather than DVT. Cyanosis of the toes indicates decreased oxygenation and is more characteristic of arterial issues. Muscle cramps in the calf are nonspecific and can be caused by various conditions, not solely DVT.

4. A client is being treated for dehydration. Which clinical finding would indicate that treatment is effective?

• A. Dry mucous membranes
• B. Increased urine output
• C. Tachycardia
• D. Hypotension

Correct answer: B

Rationale: The correct answer is B: Increased urine output. When a client is being treated for dehydration, increased urine output is a positive indication that the treatment is effective. This signifies that the body is beginning to rehydrate and eliminate excess fluid. Choices A, C, and D are incorrect because dry mucous membranes, tachycardia, and hypotension are all associated with dehydration and would not be signs of effective treatment.

5. An elderly client is concerned about constipation during a flight. What should the nurse recommend?

• A. Use an over-the-counter stool softener when needed
• B. Eat a high protein diet
• C. Increase the fluid intake in the diet
• D. Decrease the fat content in the diet

Correct answer: C

Rationale: The correct answer is to recommend increasing fluid intake in the diet. Adequate hydration is essential for preventing constipation, especially during travel when mobility may be reduced. Stool softeners are not the first-line recommendation and should only be used when necessary. Eating a high protein diet or decreasing fat content in the diet may not directly address the issue of constipation related to dehydration during a flight.
