A patient receiving IV vancomycin develops flushing, erythema, and pruritus on the face, neck, and upper torso. What is this reaction called and what is the appropriate intervention?
Answer: Red Man Syndrome; slow the infusion rate and premedicate with diphenhydramine
Red Man Syndrome is a rate-related reaction to vancomycin characterized by flushing and erythema of the upper body, managed by slowing the infusion and premedication with antihistamines.
When assessing a PICC line insertion site, the nurse notes the arm circumference has increased by 3 cm compared to the baseline. What condition does this most likely indicate?
Answer: Deep vein thrombosis (DVT)
A significant increase in arm circumference above baseline is a cardinal sign of deep vein thrombosis associated with PICC line placement.
A patient's central venous pressure (CVP) is 2 mmHg. Which clinical finding would be consistent with this value?
Answer: Flat neck veins in the supine position
A CVP of 2 mmHg is below normal (8–12 mmHg) indicating hypovolemia, which presents with flat neck veins when supine.
Which parameter is most important to assess before administering a hyperosmolar solution such as TPN through a peripheral IV catheter?
Answer: Osmolarity of the solution
Solutions with osmolarity greater than 900 mOsm/L should not be administered peripherally due to risk of phlebitis and vessel damage.
A patient has a tunneled cuffed central venous catheter. During assessment, the nurse is unable to aspirate blood from any lumen. The infusion is running without difficulty. What is the most likely cause?
Answer: Fibrin sheath formation allowing flow but not aspiration
A fibrin sheath or tail can form at the catheter tip, acting as a one-way valve that allows infusion but prevents aspiration.
Which Glasgow Coma Scale (GCS) score finding in a patient receiving high-dose opioid infusion warrants immediate intervention?
Answer: Eye opening to voice (E3)
Eye opening only to voice (E3) combined with an opioid infusion suggests sedation and respiratory depression risk requiring immediate clinical reassessment.
A patient receiving long-term TPN is noted to have a serum phosphorus of 1.2 mg/dL. What condition does this represent and what complication is most concerning?
Answer: Hypophosphatemia; respiratory muscle weakness
Hypophosphatemia in TPN patients can cause refeeding syndrome, with respiratory muscle weakness being the most life-threatening complication.
