Rationale: The correct answer is B: Soybean oil. Soybean oil is a good source of omega-3 fatty acids, which are beneficial for heart health. Blueberries (choice A), citrus fruits (choice C), and green tea (choice D) are not significant sources of omega-3 fatty acids. Blueberries are rich in antioxidants, citrus fruits provide vitamin C, and green tea contains polyphenols, but they do not offer a substantial amount of omega-3 fatty acids compared to soybean oil.

Correct Answer: B

Rationale: The correct answer is B: 'get the description of the location and intensity of the pain.' When a client complains of pain, the initial step in pain assessment is to gather information about the location and intensity of the pain. This helps the nurse understand the nature of the pain and lays the groundwork for further assessment and management. Choice A is incorrect because identifying coping methods comes later in the assessment process. Choice C is incorrect as accepting the client's report of pain is important, but not the first step. Choice D is incorrect as determining the client's pain status also comes after gathering information about the pain.

Correct Answer: C

Rationale: The correct answer is C, 'Chicken.'

Monitoring the heart rhythm and ECG findings is essential to prevent cardiac complications. Neurological status, respiratory status, and gastrointestinal status are important assessments too, but in the context of hyperkalemia, cardiac status takes precedence due to the immediate risk of cardiac arrhythmias.
