1. Which atrioventricular heart block is also referred to as Mobitz II?

• A. Third-degree atrioventricular heart block
• B. Second-degree atrioventricular heart block
• C. First-degree atrioventricular heart block
• D. Complete heart block

Correct answer: B

Rationale: The correct answer is B. Second-degree atrioventricular heart block is also known as Mobitz II. In Mobitz II, some atrial impulses are blocked from reaching the ventricles, resulting in occasional dropped beats. Third-degree atrioventricular heart block is known as complete heart block, where no atrial impulses reach the ventricles. First-degree atrioventricular heart block is a condition where there is delayed conduction between the atria and ventricles but all atrial impulses are eventually conducted to the ventricles.

2. A patient's serum potassium level is 2.2 mEq/L. Which nursing action is the highest priority for this patient?

• A. Start oxygen at 2 L/min
• B. Initiate cardiac monitoring
• C. Initiate seizure precautions
• D. Keep the patient on bed rest

Correct answer: B

Rationale: The correct answer is to initiate cardiac monitoring. Severe hypokalemia can lead to life-threatening arrhythmias, making cardiac monitoring the priority to detect and manage any cardiac complications. Starting oxygen, seizure precautions, or bed rest are not the immediate priority actions for severe hypokalemia.

3. Which of the following is a benefit of the U.S. health-care system?

• A. With cost savings from technology, more Americans now have health-care insurance.
• B. Quality of care has improved in the United States.
• C. Care in the United States has shifted to a prevention focus rather than an illness focus.
• D. The use of technology is projected to decrease health-care costs and improve clinical outcomes.

Correct answer: D

Rationale: The correct answer is D because the use of technology and electronic health records is projected to decrease health-care costs and improve clinical outcomes, quality, and safety. Choice A is incorrect because it states that very few Americans have no health-care insurance, which is not a benefit of the U.S. health-care system. Choice B may be true, but it does not directly address a benefit of the health-care system. Choice C is not necessarily a benefit but rather a shift in focus, so it is also incorrect.

4. A nurse is comparing the rate of medication errors on the medical unit to the rate from a medical unit in a magnet hospital. Which of the following quality improvement methods is the nurse using?

• A. Structure audit
• B. Benchmarking
• C. Risk benefit analysis
• D. Root cause analysis

Correct answer: B

Rationale: The correct answer is B: Benchmarking. Benchmarking involves comparing performance metrics with those from other units or institutions, which is exactly what the nurse is doing by comparing the rate of medication errors on their medical unit to the rate from a medical unit in a magnet hospital. Choice A, Structure audit, is not relevant to this scenario as it focuses on assessing the physical, organizational, or procedural structures in a healthcare setting. Choice C, Risk benefit analysis, involves weighing the potential risks and benefits of a particular course of action, not comparing performance metrics. Choice D, Root cause analysis, is a method used to identify the underlying causes of problems or adverse events, not to compare performance metrics between units.

5. 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.
