During a change-of-shift report, a nurse sees that a client's IV bag of 0.9% sodium chloride has 900 mL of fluid left in it. The nurse makes rounds 30 minutes later and notes that the IV bag is empty.
Which of the following actions should the nurse take?

Choice A rationale:

The nurse should prioritize collecting data from a client who reports unilateral calf pain when ambulating. This symptom could indicate the presence of a deep vein thrombosis (DVT), a potentially life-threatening condition. DVT occurs when a blood clot forms in a deep vein, often in the lower extremities. If left untreated, the clot can dislodge and travel to the lungs, causing a pulmonary embolism. Immediate assessment is crucial to rule out DVT and provide appropriate interventions. The nurse should assess the client's calf for swelling, redness, warmth, and tenderness and may also order diagnostic tests like a duplex ultrasound.

Choice B rationale:

Taking a telephone prescription for a client being transferred from the PACU is important but not the top priority in this situation. While timely transfer and adequate post-operative care are essential, addressing a client with unilateral calf pain and the potential for a DVT takes precedence due to the risk of a life-threatening complication.

Choice C rationale:

Reassuring the partner of a client who sustained a closed head injury is a compassionate action but should not be the first priority. The partner's emotional support can be provided once the immediate medical concerns have been addressed.

Choice D rationale:

Reinforcing a client's dressing on an above-the-knee amputation surgical site is important for the client's post-operative care, but it is not the highest priority when compared to the possibility of a DVT. The nurse should address the client's calf pain first and then attend to the dressing reinforcement.

The correct answer is C.

Choice A: Oxygen saturation of 95% The normal oxygen saturation level is between 95% and 100%. An oxygen saturation of 95% is within the normal range, so the nurse would not need to withhold furosemide for this reason.

Choice B: Serum sodium level of 140 mEq/L The normal serum sodium levels range from 135 to 145 mEq/L. A serum sodium level of 140 mEq/L is within the normal range, so the nurse would not need to withhold furosemide for this reason.

Choice C: Blood pressure of 80/40 mm Hg Furosemide is a potent diuretic that can lead to a significant depletion of electrolytes, which may lead to side effects such as muscle cramps and an irregular heartbeat. Low blood pressure (hypotension) is a potential side effect of furosemide. Normal blood pressure for adults is typically around 120/80 mm Hg. A blood pressure reading of 80/40 mm Hg is considerably lower than the normal range, indicating hypotension.

Choice D: Serum potassium level of 4.8 mEq/L The normal serum potassium levels range from 3.6 to 5.2 mEq/L. A serum potassium level of 4.8 mEq/L is within the normal range, so the nurse would not need to withhold furosemide for this reason.
