What is the normal value (NV) for sodium in the blood.
3.5-5 mEq/L.
9-10.5 mg/dL.
135-145 mEq/L.
96-106 mEq/L.
The Correct Answer is C
According to Healthline1 and Mayo Clinic, the normal blood sodium level is between 135 and 145 milliequivalents per liter (mEq/L).
Choice A is wrong because it is the normal range for potassium, not sodium.
Choice B is wrong because it is the normal range for calcium, not sodium.
Choice D is wrong because it is the normal range for chloride, not sodium

Correct Answer is ["B","C","D"]
Explanation
Hypercalcemia is a condition in which the calcium level in the blood is above normal.
This can cause various symptoms, such as confusion, constipation, and bradycardia (slow heart rate).
These are the clinical manifestations that the nurse would expect to observe in a client with hypercalcemia.
Choice A is wrong because muscle spasms are not a common symptom of hypercalcemia.
In fact, hypercalcemia can cause muscle weakness and pain.
Choice E is wrong because polyuria (excessive urination) is not a direct symptom of hypercalcemia, but rather a result of kidney problems caused by hypercalcemia.
Hypercalcemia can make the kidneys work harder to filter the excess calcium, leading to dehydration and thirst.
However, this does not necessarily mean that the client will have polyuria.
Normal ranges for calcium levels in the blood are 8.5 to 10.2 mg/dL (milligrams per deciliter) or 2.1 to 2.6 mmol/L (millimoles per liter).
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.
