Nursing Elites

1. What are the primary pathophysiological mechanisms responsible for ascites in liver failure?

• A. Decreased liver enzymes.
• B. Increased hydrostatic pressure in portal circulation.
• C. High bilirubin levels.
• D. Fluid shifts due to decreased serum proteins.

Correct answer: B

Rationale: The correct answer is B: Increased hydrostatic pressure in portal circulation. Ascites in liver failure is primarily caused by fluid shifts from the intravascular space to the interstitial space due to increased hydrostatic pressure in the portal circulation. Choice A is incorrect as ascites is not caused by decreased liver enzymes. Choice C is incorrect as high bilirubin levels are not the primary mechanism for ascites in liver failure. Choice D is incorrect as fluid shifts in ascites are due to decreased serum proteins, not increased serum proteins.

2. When monitoring tissue perfusion following an above the knee amputation (AKA), which action should the nurse include in the plan of care?

• A. Evaluate the closest proximal pulse.
• B. Observe the color and amount of wound drainage.
• C. Observe for swelling around the stump.
• D. Assess the skin elasticity of the stump.

Correct answer: A

Rationale: Evaluating the closest proximal pulse is essential when monitoring tissue perfusion post-amputation. This pulse provides crucial information about the circulation and perfusion to the limb. Observing the color and amount of wound drainage (Choice B) is more related to wound healing assessment rather than tissue perfusion. Observing for swelling around the stump (Choice C) may indicate inflammation or infection but is not the most direct assessment of tissue perfusion. Assessing skin elasticity of the stump (Choice D) is important for skin integrity but does not directly reflect tissue perfusion.

3. The nurse is caring for a client in atrial fibrillation. The atrial heart rate is 250, and the ventricular rate is controlled at 75. Which of the following findings is cause for the most concern?

• A. Diminished bowel sounds
• B. Loss of appetite
• C. A cold, pale lower leg
• D. Tachypnea

Correct answer: C

Rationale: A cold, pale lower leg is cause for the most concern as it could indicate compromised blood circulation, potentially leading to serious complications like ischemia or thrombosis. Diminished bowel sounds, loss of appetite, and tachypnea are not directly related to the client's condition in atrial fibrillation and the heart rate discrepancy.

4. The nurse is providing care for a client with heart failure who is prescribed furosemide. Which laboratory value should the nurse monitor closely?

• A. Calcium level
• B. Sodium level
• C. Magnesium level
• D. Potassium level

Correct answer: D

Rationale: The correct answer is D: Potassium level. Furosemide is a loop diuretic that can cause potassium loss, leading to hypokalemia. Monitoring potassium levels is crucial to prevent complications such as cardiac arrhythmias. While calcium, sodium, and magnesium levels are important in various conditions and treatments, they are not the primary electrolyte affected by furosemide.

5. A client with type 1 diabetes is found unconscious with a blood glucose of 40 mg/dL. What is the nurse's priority intervention?

• A. Administer a 50% dextrose bolus intravenously.
• B. Administer glucagon intramuscularly.
• C. Provide oral glucose gel.
• D. Recheck the blood glucose level in 15 minutes.

Correct answer: A

Rationale: The correct answer is to administer a 50% dextrose bolus intravenously. In unconscious clients with hypoglycemia, IV dextrose rapidly raises the blood glucose level. Glucagon would be a slower option and is typically used if IV access is unavailable. Oral glucose gel is not appropriate for an unconscious client as it requires swallowing and may cause aspiration. Rechecking the blood glucose level in 15 minutes delays immediate treatment and could lead to further deterioration.
