The nurse caring for a client reviews the medical record and determines the client is at risk for developing a potassium deficit because of which situation?
History of Addison's disease.
Has sustained tissue damage.
Uric acid level of 9.4 mg/dL.
Requires nasogastric suction.
The Correct Answer is D
Nasogastric suction removes gastric secretions that contain potassium, leading to a loss of potassium from the body. This can cause hypokalemia, which is a low level of potassium in the blood.
Choice A is wrong because Addison’s disease causes hyperkalemia, which is a high level of potassium in the blood.
Choice B is wrong because tissue damage can release potassium from the cells into the blood, causing hyperkalemia.
Choice C is wrong because uric acid level is not related to potassium level.
Uric acid is a waste product of purine metabolism that can cause gout or kidney stones if elevated.

Correct Answer is A
Explanation
The correct answer is A. 42 mL/h.
Choice A: 42 mL/h
Reason: To calculate the IV rate, we use the formula: IV rate (mL/h) = Total volume (mL) ÷ Total time (hours). For this problem, the total volume is 1000 mL and the total time is 24 hours. Therefore, the calculation is 1000 mL ÷ 24 hours = 41.6667 mL/h. When rounded to the nearest whole number, the IV rate is 42 mL/h. This makes 42 mL/h the correct answer.
Choice B: 44 mL/h
Reason: This choice is incorrect because it does not match the calculated IV rate. The calculation of 1000 mL ÷ 24 hours results in 41.6667 mL/h, which rounds to 42 mL/h, not 44 mL/h. Therefore, 44 mL/h is not a valid option based on the given data.
Choice C: 46 mL/h
Reason: This choice is also incorrect. The calculated IV rate of 41.6667 mL/h, when rounded to the nearest whole number, is 42 mL/h. There is no mathematical basis for rounding up to 46 mL/h from 41.6667 mL/h, making this choice invalid.
Choice D: 48 mL/h
Reason: This choice is incorrect as well. The correct calculation yields 41.6667 mL/h, which rounds to 42 mL/h. There is no justification for rounding up to 48 mL/h. This choice does not align with the calculated and rounded IV rate.
Correct Answer is A
Explanation
Increased urine output is a sign of adequate hydration, as it means the kidneys are filtering waste and fluids from the body through the urine. The urine should be pale straw or lemonade colored, which indicates good hydration.
Choice B is wrong because decreased urine output is a sign of dehydration, as it means the kidneys are not working well and waste products are accumulating in the blood.
The urine may be dark and strong smelling, which indicates poor hydration.
Choice C is wrong because dry mucous membranes are a sign of dehydration, as they indicate a lack of fluid in the body tissues.
Choice D is wrong because hypertension is not a direct indicator of hydration status, although dehydration can cause low BP due to reduced blood volume.
