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.

Correct Answer: B

Rationale: The correct answer is B. When rounding off to the nearest tenth, 1.027 becomes 1.0 because the digit in the hundredth's place is less than 5. For the other numbers, they are rounded correctly to the nearest tenth: 5.5778 = 5.6, 62.999 = 63, 55.123 = 55.1, 96.676 = 96.7. Therefore, option B is the most accurate in rounding off these numbers to the nearest tenth. Choices A, C, and D are incorrect as they do not round 1.027 to 1.0 as required when rounding to the nearest tenth.

Correct Answer: C

Rationale: Effacement is the correct term for the softening and thinning of the cervix during labor. It is the process where the cervix becomes thinner, allowing it to stretch and open as labor progresses. Choice A, 'Dilation,' is incorrect as it refers to the opening of the cervix. Choice B, 'Symphysis,' is incorrect as it refers to the joint that connects the two pubic bones. Choice D, 'Hyperplasia,' is incorrect as it refers to an increase in the number of cells in an organ or tissue.

Correct Answer: C

Rationale: In a triage situation, an asymmetrical thorax suggests a potentially life-threatening condition such as a pneumothorax or hemothorax, requiring immediate attention. This client should be tagged as emergent. Periorbital ecchymosis and deep-partial thickness burns, while concerning, may not indicate an immediate life-threatening situation. An open fracture of the femur, although serious, can be prioritized after addressing emergent cases.

Correct Answer: A

Rationale: The correct principle of teaching to follow when reinforcing teaching and instructing the patient is to sequence the instruction from the least complex to the most complex. This approach facilitates learning by building upon simpler concepts before moving to more advanced ones. Choice B is incorrect because assuming the patient knows little or nothing about the topic may not always be accurate and can be patronizing. Choice C is incorrect as it does not focus on the direct teaching approach to the patient. Choice D is incorrect as using medically oriented terms may confuse the patient rather than facilitate understanding.
