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: A

Rationale: The correct answer is A, the Trendelenburg position. This position involves placing the patient with their legs elevated higher than their head. It is used to increase blood flow to the upper body, including the brain and heart, in cases of hypovolemic shock. This helps improve perfusion to vital organs.

Choices B, C, and D are incorrect as they do not facilitate the desired redistribution of blood flow needed in hypovolemic shock. The supine position is lying flat on the back, the left lateral position is lying on the left side, and the right lateral position is lying on the right side.

Correct Answer: C

Rationale: The best way for a nurse to improve the quality of care is by collaborating with other health-care professionals, patients, and their families. By working together with the healthcare team, patients, and families, nurses can ensure a holistic approach to care delivery, leading to better outcomes.

Choices A and D are incorrect as they focus solely on physicians, while choice B, though important, does not fully encompass the collaborative aspect necessary for comprehensive care.

Correct Answer: B

Rationale: Oranges are not high in magnesium. The other choices, such as peas, are good sources of magnesium. Peas, along with cauliflower and canned white tuna, are foods rich in magnesium. Oranges, although healthy, are not known for their high magnesium content.

Correct Answer: C

Rationale:
To calculate the drops per minute, first convert the ordered amount to drops per minute. 20 cc per hour equals 20 drops per hour with 60 cc per drop tubing, which is equivalent to 20 drops per hour * 60 cc per drop = 1200 drops per hour.
To find drops per minute, divide 1200 by 60 (minutes in an hour), which equals 20 drops per minute.
Therefore, the correct answer is 20 drops per minute.

Choices A, B, and D are incorrect as they do not reflect the correct calculation based on the provided information.
