Nursing Elites

1. A nurse reviews the electrolyte results of an assigned client and notes that the potassium level is 5.4 mEq/L. Which of the following would the nurse expect to note on the electrocardiogram as a result of the laboratory value?

• A. ST depression
• B. Inverted T wave
• C. Prominent U wave
• D. Tall peaked T waves

Correct answer: D

Rationale: The correct answer is 'Tall peaked T waves.' Tall peaked T waves are characteristic ECG changes associated with hyperkalemia. In hyperkalemia, the elevated potassium levels affect the myocardium, leading to changes in the ECG. ST depression (Choice A) is more commonly associated with myocardial ischemia or infarction. Inverted T wave (Choice B) is seen in conditions like myocardial ischemia or CNS events. Prominent U wave (Choice C) is typically associated with hypokalemia or certain medications. Therefore, in this scenario, the nurse would expect to note tall peaked T waves on the electrocardiogram due to the elevated potassium level.

2. Which of the following best describes evidence-based practice?

• A. Using outdated research
• B. Relying on personal experience alone
• C. Integrating clinical expertise with the best available evidence
• D. Disregarding patient preferences

Correct answer: C

Rationale: Evidence-based practice involves integrating clinical expertise with the best available evidence to make informed decisions about patient care. Choice A is incorrect as evidence-based practice relies on current and relevant research. Choice B is incorrect as it emphasizes the importance of not relying solely on personal experience. Choice D is incorrect as patient preferences play a significant role in evidence-based practice.

3. A client is in DKA, secondary to infection. As the condition progresses, which of the following symptoms might the nurse see?

• A. Kussmaul's respirations and a fruity odor on the breath
• B. Shallow respirations and severe abdominal pain
• C. Decreased respirations and increased urine output
• D. Cheyne-Stokes respirations and foul-smelling urine

Correct answer: A

Rationale: In diabetic ketoacidosis (DKA), as the condition progresses, the body tries to compensate for the acidic environment by increasing the respiratory rate, leading to Kussmaul's respirations. The accumulation of ketones in the body causes a fruity odor on the breath. Option A is correct because Kussmaul's respirations and a fruity odor on the breath are classic signs of DKA. Option B is incorrect because shallow respirations are not typically seen in DKA, and severe abdominal pain is more commonly associated with conditions like pancreatitis. Option C is incorrect as decreased respirations are not a typical finding in DKA, and increased urine output is more commonly seen in conditions like diabetes insipidus. Option D is incorrect because Cheyne-Stokes respirations are not characteristic of DKA, and foul-smelling urine is not a prominent symptom in this condition.

4. Select the ethical principles that are paired with their descriptions. Select the one that does not apply.

• A. Justice: Being honest and fair
• B. Beneficence: Doing good
• C. Veracity: Truthfulness
• D. Self-determination: Facilitating patient choices

Correct answer: C

Rationale: The correct answer is C. Veracity is the principle of truthfulness, not treating all patients equally. Choice A is correct as Justice involves being honest and fair. Choice B is correct as Beneficence is about doing good. Choice D is correct as Self-determination is about respecting and facilitating patient choices.

5. Which healthcare-associated infection poses the greatest risk for patients?

• A. Pneumonia
• B. Catheter-related infections
• C. Intravenous line infections
• D. C. difficile

Correct answer: B

Rationale: Catheter-related infections pose the greatest risk for patients in healthcare settings. Catheters are invasive devices that can introduce pathogens directly into the bloodstream, leading to severe infections. Pneumonia, intravenous line infections, and C. difficile infections are serious concerns as well, but catheter-related infections are particularly risky due to the direct access they provide for pathogens to enter the body.
