Nursing Elites

1. What is the most common cause of HHNS?

• A. Insulin overdose
• B. Removal of the adrenal gland
• C. Undiagnosed, untreated hyperpituitarism
• D. Undiagnosed, untreated diabetes mellitus

Correct answer: D

Rationale: The correct answer is D: Undiagnosed, untreated diabetes mellitus. Hyperosmolar hyperglycemic nonketotic syndrome (HHNS) is most commonly caused by undiagnosed and untreated diabetes mellitus. Insulin overdose (Choice A) is not a typical cause of HHNS; it is more related to hypoglycemia. Removal of the adrenal gland (Choice B) can lead to adrenal insufficiency but is not a common cause of HHNS. Undiagnosed, untreated hyperpituitarism (Choice C) is not a usual cause of HHNS; it is more related to pituitary hormone imbalances rather than hyperglycemia.

2. 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.

3. A case manager is preparing a discharge plan for a client following coronary artery bypass grafting surgery. Which of the following client issues should the nurse address first?

• A. Inadequate food supply
• B. Low pain tolerance
• C. Limited social support
• D. Decreased self-esteem

Correct answer: A

Rationale: The nurse should address the inadequate food supply first as it directly impacts the client's health post-discharge. Proper nutrition is crucial for recovery after surgery, especially such as coronary artery bypass grafting. While low pain tolerance, limited social support, and decreased self-esteem are all important issues to address, addressing the client's nutritional needs is the priority in this scenario to ensure optimal recovery and healing.

4. 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.

5. Why is patient confidentiality significant in healthcare?

• A. Sharing patient information freely
• B. Protecting patient privacy
• C. Ignoring patient consent
• D. Limiting patient access to their own records

Correct answer: B

Rationale: Patient confidentiality is significant in healthcare because it involves protecting patient privacy. Maintaining confidentiality ensures that patients feel safe and secure when sharing sensitive information with healthcare providers. Choice A is incorrect because sharing patient information freely would violate confidentiality. Choice C is incorrect because ignoring patient consent goes against ethical principles. Choice D is incorrect because limiting patient access to their own records does not relate directly to the concept of patient confidentiality.
