Correct Answer: A

Rationale: The correct answer is A: 1 in 85 births. The rate of twin pregnancies is approximately 1 in 85 births. This means that twins are more common compared to triplets, which occur at a rate of 1 in 8,100 births. Choices B, C, and D are incorrect because they do not reflect the correct frequency of twin pregnancies as stated in the question.

Correct Answer: B

Rationale: The correct answer is to identify the medication name and dosage administered to the client in the incident report. This information is crucial for accurate documentation and investigation of the medication error. Choice A is incorrect because incident reports are usually kept confidential and not for personal keeping. Choice C is incorrect as obtaining an order from the client's provider is not necessary to complete an incident report. Choice D, while important, is not the only essential information needed for the incident report.

Correct Answer: B

Rationale: The main objective of palliative care is to provide relief from symptoms and improve quality of life. Palliative care focuses on enhancing the quality of life for patients facing serious illnesses by providing relief from symptoms such as pain, stress, and other physical and emotional issues. Choice A is incorrect because palliative care does not aim to cure the disease but rather to manage symptoms. Choice C is incorrect as the goal of palliative care is not to extend hospital stays unnecessarily but to improve the patient's well-being. Choice D is incorrect as palliative care is not solely focused on treatment but takes a holistic approach to care that includes addressing physical, emotional, social, and spiritual needs.

Correct Answer: C

Rationale: The correct answer is C: Kidney dialysis. A blood potassium level of 9.2 mEq/L indicates severe hyperkalemia, which can be life-threatening. Kidney dialysis is the most appropriate intervention to rapidly lower potassium levels in this situation. Choice A, intravenous potassium supplementation, would worsen the hyperkalemia. Choice B, intravenous calcium supplementation, is not the primary intervention for hyperkalemia. Choice D, parenteral nutrition, is unrelated to treating hyperkalemia and would not address the immediate concern.

Correct Answer: C

Rationale: The nurse should contact the case manager to discuss discharge options and support the client's partner. This action is appropriate as it involves seeking professional guidance and support for the client's partner who is struggling to care for the client. Option A is not the best choice as it solely focuses on involving another family member without addressing the partner's concerns directly. Option B is premature as recommending long-term care should be a well-considered decision involving multiple healthcare professionals. Option D delays the inevitable without providing a solution to the partner's current challenges.
