Which adverse effect of heparin sodium therapy, delivered continuously by intravenous infusion, should the nurse monitor the client for?
Correct Answer: B
Rationale: Heparin sodium is an anticoagulant. The client who receives heparin sodium is at risk for bleeding.

The remaining options are not related side or adverse effects of this medication.

An infusion of lidocaine hydrochloride (Xylocaine) is running at 30 mL/hour. The dilution is 1,000 mg/250 mL. What dosage is the client receiving per minute?
Correct Answer: 2 mg/minute.
Rationale: Calculate: 1,000 mg in 250 mL = 4 mg/mL. At 30 mL/hour, that's 30 mL × 4 mg/mL = 120 mg/hour. Per minute: 120 mg ÷ 60 min = 2 mg/minute.
