ATI N211 Pharmacology Exam Questions

Extract:


Question 1 of 5

A nurse is preparing to administer 0.45% sodium chloride (NaCl) 1000 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: 125

Rationale:
To calculate the rate of infusion, divide the total volume by the total time in hours. In this case, 1000 mL รท 8 hr = 125 mL/hr. This is the correct answer because it ensures the proper administration of the IV solution over the specified time frame. Other choices are incorrect because they do not align with the calculation. For example, choices below 125 would result in a slower infusion rate, potentially causing underdosing, while choices above 125 would result in a faster rate, risking potential complications from rapid infusion. It is crucial to set the IV pump accurately to maintain patient safety and therapeutic effectiveness.
