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. 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.

3. A nurse is orienting a newly licensed nurse about client confidentiality. Which of the following statements by the newly licensed nurse indicates an understanding of the teaching?

A. I can use another nurse's password as long as I log off after using the computer
B. I should encrypt personal health information when sending emails
C. I can post the client's vital signs in the client's room
D. I should discard personal health information documents in the trash before leaving the unit

Correct answer: B

Rationale: The correct answer is B because encrypting personal health information when sending emails is a crucial aspect of maintaining client confidentiality. This process ensures that sensitive information is protected during electronic communication. Choice A is incorrect as sharing passwords violates client confidentiality. Choice C is incorrect as posting client's vital signs breaches confidentiality. Choice D is incorrect as discarding personal health information in the trash can lead to unauthorized access.

4. A patient is admitted to the emergency department with hypovolemia. Which IV solution should the nurse anticipate administering?

A. 3% sodium chloride
B. 10% dextrose in water
C. 0.45% sodium chloride
D. Lactated Ringer's solution

Correct answer: D

Rationale: Lactated Ringer's solution is the most suitable IV solution for a patient with hypovolemia. It is a balanced crystalloid solution containing electrolytes such as sodium, chloride, potassium, calcium, and lactate, which closely resemble the body's natural fluids. This solution helps to restore intravascular volume and electrolyte balance in hypovolemic patients. Choice A, 3% sodium chloride, is a hypertonic solution used for specific situations like severe hyponatremia or cerebral edema, not typically for hypovolemia. Choice B, 10% dextrose in water, is a hypertonic solution primarily used for providing calories and free water, not for volume expansion. Choice C, 0.45% sodium chloride, is a hypotonic solution used for conditions like hypernatremia or as maintenance fluid, not for hypovolemia.

5. Which of the following foods enhances the absorption of an iron supplement?

A. Orange juice
B. Green beans
C. Fortified milk
D. Baked potato

Correct answer: A

Rationale: The correct answer is Orange juice. Orange juice enhances the absorption of an iron supplement due to its high vitamin C content. Vitamin C helps in the absorption of non-heme iron, the type of iron found in plant-based foods and iron supplements. Green beans, fortified milk, and baked potato do not have the same level of vitamin C as orange juice, making them less effective in enhancing iron absorption.
