Passage / Scenario
Administer 5% dextrose in 0.45% sodium chloride 1,000 mL IV to infuse over 12 hr.A nurse is preparing to administer 5% dextrose in 0.45% sodium chloride 1,000 mL IV to infuse over 12 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
A
Rationale
To calculate the IV rate, first add the percentages of dextrose and sodium chloride (5% + 0.45% = 5.45%). Then, divide by the number of hours to infuse (1000 mL / 12 hr = 83.33 mL/hr). Since we need to round to the nearest whole number, the IV pump should be set to deliver 83 mL/hr. Choice A (83) is correct because it reflects the calculated infusion rate. Other choices are incorrect as they do not accurately represent the calculated rate.
