Nursing Elites

1. A nurse is assessing a client who has acute pancreatitis and is at risk for an acid-base imbalance. For which manifestation of this acid-base imbalance should the nurse assess?

• A. Agitation
• B. Kussmaul respirations
• C. Seizures
• D. Positive Chvosteks sign

Correct answer: Kussmaul respirations

Rationale:

2. A patient with hypokalemia and heart failure is admitted to the telemetry unit. The nurse is aware that hypokalemia could cause which of the following abnormalities on an electrocardiogram (ECG)?

• A. Shortened P-R interval
• B. Inverted T wave
• C. Depressed U wave
• D. Elevated U wave

Correct answer: D

Rationale: The correct answer is D: Elevated U wave. Hypokalemia is associated with ECG changes such as an elevated U wave and flattened T waves. Choice A, a shortened P-R interval, is not typically seen in hypokalemia. Choice B, an inverted T wave, is more commonly associated with ischemia or CNS injury rather than hypokalemia. Choice C, a depressed U wave, is not a typical ECG abnormality seen in hypokalemia. Therefore, the correct ECG abnormality associated with hypokalemia is an elevated U wave.

3. You are the nurse caring for a 77-year-old male patient who has been involved in a motor vehicle accident. You and your colleague note that the patients labs indicate minimally elevated serum creatinine levels, which your colleague dismisses. What can this increase in creatinine indicate in older adults?
