Nursing Elites

1. 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.

2. 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.

3. Which of the following is the best way for a nurse to improve quality of care?

• A. Recognize that physicians are among the health-care professionals interested in improving quality of care.
• B. Work with patients and families to improve healthcare.
• C. Collaborate with other health-care professionals, patients, and their families.
• D. Recognize that physicians are among the numerous professionals in health care.

Correct answer: C

Rationale: The best way for a nurse to improve the quality of care is by collaborating with other health-care professionals, patients, and their families. By working together with the healthcare team, patients, and families, nurses can ensure a holistic approach to care delivery, leading to better outcomes. Choices A and D are incorrect as they focus solely on physicians, while choice B, though important, does not fully encompass the collaborative aspect necessary for comprehensive care.

4. A nurse is assessing a client with a suspected diagnosis of hypocalcemia. Which of the following clinical manifestations would the nurse expect to note in the client?

• A. Twitching
• B. Positive Trousseau's sign
• C. Hyperactive bowel sounds
• D. Hyperactive deep tendon reflexes

Correct answer: A

Rationale: The correct answer is A: Twitching. Hypocalcemia often presents with neuromuscular irritability, leading to manifestations such as twitching. Trousseau's sign is actually a positive indicator of hypocalcemia, not negative, making choice B incorrect. Hypoactive bowel sounds are not typically associated with hypocalcemia, making choice C incorrect. Similarly, hypoactive deep tendon reflexes are not a common finding in hypocalcemia, making choice D incorrect.

5. Which of the following most accurately describes a current concern in health care today?

• A. Health care-associated (nosocomial) infections continue to increase, not limited to health-care settings.
• B. Despite preventable deaths increasing from the opioid crisis, life expectancy in the United States has slightly risen over the last 2 years.
• C. Although adverse drug events persist, medication errors have not been completely eliminated through the use of electronic medication administration records.
• D. Gun violence has become a growing public health concern.

Correct answer: D

Rationale: Gun violence has become a growing public health concern due to the increasing rates of injury and death caused by the misuse of firearms. Choice A is incorrect because health care-associated infections are not limited to health-care settings and continue to increase. Choice B is inaccurate as preventable deaths from the opioid crisis have not led to a rise in life expectancy in the United States. Choice C is incorrect as medication errors have not been completely eliminated despite the use of electronic medication administration records.
