Extract:
Question 1 of 5
A nurse is preparing to administer lactated Ringer's solution IV to infuse at 120 mL/hr for a client who has a respiratory disorder. The drop factor on the manual IV tubing is 60 gtt/mL. The nurse should set the IV flow rate to deliver how many gtt/min?(Round to the nearest whole number.)
Correct Answer: A
Rationale: Using the formula Flow rate (gtt/min) = (Volume/Time) × Drop factor, 120 mL/60 min × 60 gtt/mL = 120 gtt/min.
Question 2 of 5
A nurse is collecting data from a client who has acute gastroenteritis. Which of the following data collection findings should the nurse identify as the priority?
Correct Answer: A
Rationale: A potassium level of 2.5 mEq/L is critically low and can cause life-threatening cardiac dysrhythmias, requiring immediate intervention.
Question 3 of 5
While assessing an older adult patient with fluid excess, the nurse notes the following: T = 98.6°F, P = 92, R = 18, BP = 166/88 mm Hg, bilateral crackles, oxygen saturation = 95%. Which action should the nurse take first?
Correct Answer: C
Rationale: Placing the patient in a high Fowler position maximizes lung expansion and alleviates dyspnea caused by fluid overload.
Question 4 of 5
Which is the most reliable method for monitoring improvement when restoring fluid balance?
Correct Answer: D
Rationale: Daily weights directly reflect changes in fluid retention or loss, providing the most reliable measure of fluid balance.

Correct Answer: A
Rationale: Using the formula Flow rate (gtt/min) = (Volume/Time) × Drop factor, 120 mL/60 min × 60 gtt/mL = 120 gtt/min.
