Question 3 of 4
A client with heart failure is receiving intravenous fluids at 125 ml/hour. The nurse observes an increase in jugular vein distention and pedal edema. Which additional assessment should the nurse make before reporting to the healthcare provider?
Correct Answer: C
Rationale: Before reporting worsening heart failure signs like jugular vein distention and pedal edema, the nurse should assess for a change in breathing pattern. These symptoms suggest fluid overload, which can lead to pulmonary edema, a life-threatening complication. Altered breathing (e.g., dyspnea, crackles) indicates the heart's inability to handle the IV fluid load, necessitating urgent intervention like diuretics or rate adjustment. Calf inflammation, vein distention, and pulse volume are less immediate than respiratory status in this context.
Question 4 of 4
The healthcare provider prescribed D5W 1800 ml IV to infuse in 24 hours. The IV administration set delivers 60 microdrops/ml. The nurse should program how many ml/hour?
Correct Answer: B
Rationale: To calculate the IV rate for 1800 ml of D5W over 24 hours, divide total volume by time: 1800 ml ÷ 24 hr = 75 ml/hr. The microdrop factor (60 drops/ml) is irrelevant for programming the pump, which uses ml/hr. 50 ml/hr (1200 ml/day) is too slow, 100 ml/hr (2400 ml) and 125 ml/hr (3000 ml) exceed the order, confirming 75 ml/hr as the correct rate to deliver the prescribed fluid accurately.
