A nurse is teaching a client who has acute kidney injury about dietary sources of potassium. Which of the following statements by the client indicates an understanding of the teaching?
"I will enjoy eating cantaloupe for my morning snack."
"I can easily add baked potatoes to my diet."
"Eating yogurt will be a new experience."
"Adding pecans will be a change I can readily make."
The Correct Answer is D
Choice A rationale: Cantaloupe is high in potassium. Clients with acute kidney injury (AKI) have impaired potassium excretion, and consuming high-potassium foods increases the risk of hyperkalemia, which can lead to cardiac arrhythmias.
Choice B rationale: Baked potatoes contain significant potassium, especially in the skin. In AKI, potassium retention is dangerous, so this choice reflects poor understanding of dietary restrictions for renal safety.
Choice C rationale: Yogurt is rich in potassium and phosphorus. In AKI, both electrolytes may accumulate due to reduced renal clearance, making yogurt an inappropriate choice without close monitoring.
Choice D rationale: Pecans are low in potassium, making them a safer snack for clients with AKI. Choosing low-potassium foods demonstrates appropriate understanding of renal dietary management.

Correct Answer is D
Explanation
Choice A reason: While a heart atack is a serious condition, it is not directly related to peritonitis. Peritonitis can lead to systemic infection, which may indirectly affect the heart, but it is not the primary concern in the immediate care of peritonitis.
Choice B reason: Diabetes is a chronic condition that requires ongoing management. However, it is not the most immediate threat when a client is diagnosed with peritonitis. The nurse should continue to monitor blood glucose levels as part of routine care.
Choice C reason: Respiratory failure can be a complication of peritonitis if the infection spreads and affects other systems. However, the primary concern with peritonitis is the potential for the infection to lead to sepsis.
Choice D reason: Sepsis is a life-threatening condition that can occur as a complication of peritonitis. It happens when the body's response to infection causes injury to its own tissues and organs. Monitoring for signs of sepsis is crucial because early intervention can be lifesaving.
Correct Answer is D
Explanation
The correct answer is D. Urine output 75 mL in 1 hr.
Adequate urine output (at least 30 mL/hr) indicates effective hydration, showing that the kidneys are functioning properly and fluid balance is improving. A urine output of 75 mL in 1 hour suggests sufficient fluid replacement.
Here’s why the other options are incorrect:
-
A. Urine specific gravity 1.005 to 1.030 – This range covers both normal and abnormal values. In dehydration, urine specific gravity is usually high (>1.030) due to concentrated urine. Effective treatment should lead to lower urine specific gravity, but the full range does not confirm improvement.
-
B. Decreased pulse pressure – Pulse pressure is the difference between systolic and diastolic blood pressure. Dehydration typically causes a narrowed pulse pressure, so improvement should lead to a normal or increased pulse pressure rather than a decrease.
-
C. Lightheadedness – Dizziness and lightheadedness are signs of dehydration-related hypotension. Effective hydration should resolve these symptoms, not maintain them.
