Correct Answer: C

Rationale: The correct answer is C: Expert. An RN with excellent assessment and psychomotor skills derives power from their expertise in the field. They are respected and trusted for their knowledge and abilities, giving them influence over others. Rewards (A) and coercion (B) are forms of power derived from external factors like incentives or threats, not skills. Legitimate power (D) comes from one's position or title, not necessarily from skills. In this case, the RN's power comes from their expertise, making choice C the most appropriate answer.

Correct Answer: B

Rationale: The correct answer is B: Decision support. In this scenario, the nurse received an alert regarding a potential drug interaction between the patient's potassium level and the scheduled digoxin. Decision support in EHR provides real-time clinical guidance to healthcare providers, helping them make informed decisions to improve patient safety. Holding the medication in response to the alert demonstrates the effective use of decision support to prevent adverse drug events. Choices A, C, and D do not directly relate to the situation described and do not involve the clinical decision-making support provided by EHRs.

Correct Answer: B

Rationale: The correct answer is B because it demonstrates empathy by acknowledging and validating the spouse's feelings of anger. By stating, "I understand how you could feel angry about the diagnosis," the nurse shows compassion and understanding towards the spouse's emotional response. This response helps to build trust and rapport with the patient's spouse during a difficult time. Choice A is incorrect as it focuses more on providing information rather than acknowledging the spouse's emotions. Choice C is incorrect as it does not address the spouse's feelings of anger and is not relevant to the situation. Choice D is incorrect as it comes across as confrontational and may make the spouse feel defensive.

Correct Answer: C

Rationale: The correct answer is C: Insurance company. In the triad of health care, the third-party payer refers to an entity outside of the patient and health care provider that pays for the health care services. Insurance companies typically serve as third-party payers by covering a portion or all of the costs associated with medical treatments. The other choices (A, B, D) are not considered third-party payers in this context. Choice A refers to the client/patient receiving the health care services, choice B refers to the health care provider delivering the services, and choice D refers to a government agency that sets reimbursement rules but does not directly pay for the services rendered.

Correct Answer: C
