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: 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.

Correct Answer: A

Rationale: An episiotomy is a surgical incision of the perineum to prevent tearing during delivery. This procedure is performed to widen the vaginal opening and facilitate childbirth. Choice B is incorrect as it describes the expulsion of the mucus plug, not an episiotomy. Choice C is incorrect as it refers to a different procedure, a cesarean section, where the baby is delivered through an incision in the abdomen. Choice D is incorrect as it pertains to cutting the umbilical cord, which is not related to an episiotomy.

Correct Answer: B

Rationale: Student nurses, licensed practical nurses, the Vice President for nursing investigating a fall, and quality assurance nurses have a 'need to know' basis to access patient records. Registered nurses who are not directly involved in the care of a patient do not have a legitimate reason or 'need to know' to access that patient's medical records, making choice B the correct answer. The Vice President for nursing investigating a specific incident and licensed practical nurses directly involved in a patient's care have legitimate reasons to access the medical records, ensuring continuity and quality of care.

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.
