A nurse is preparing to administer 0.45% sodium chloride (NaCl) 2000 mL IV to infuse over 8 hr. The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["250"]

Correct Answer is C
Explanation
A. Hyperglycemia typically presents with symptoms such as polyuria, polydipsia, and blurred vision, rather than these symptoms.
B. Neuropathy involves symptoms like numbness and tingling, not headache, restlessness, fatigue, and hunger.
C. Hypoglycemia presents with symptoms including headache, restlessness, fatigue, and hunger.
D. Hypokalemia presents with symptoms like muscle weakness and cramping, not the symptoms described.
Correct Answer is ["24"]
Explanation
- First, determine the concentration of the heparin solution. In this case, it's 25,000 units in 500 mL, which means there are 50 units per mL.
- Next, calculate the required rate to deliver 1,200 units per hour. Since the concentration is 50 units per mL, divide 1,200 units by 50 units/mL to find the required mL per hour.
- The calculation will be 1,200 units/hr ÷ 50 units/mL = 24 mL/hr.
- Since the question asks to round to the nearest tenth or whole number, and the result is a whole number, the IV pump should be set to deliver 24.0 mL/hr.
