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.)
Correct answer
250
Rationale
Certainly! The correct answer is 250. To determine this, we need to understand place value. In the number 250, the digit 2 represents 200 (hundreds place), the digit 5 represents 50 (tens place), and the digit 0 represents 0 (ones place). Therefore, the number 250 can be broken down as 200 + 50 + 0 = 250. The other choices do not add up to 250 when considering their place values. Choice A is less than 250, choices B, C, D, and E are greater than 250, and choices F and G have incorrect values. Thus, 250 is the only option that correctly represents the value based on the place value system.
