Explanation
Titrate norepinephrine to the ordered MAP target and use invasive arterial pressure monitoring when available for a client in shock (Choice 1). Use smart-pump safeguards and complete independent verification as required by facility policy (Choice 3). Monitor glucose and titrate insulin at protocol-defined intervals, commonly hourly until stable (Choice 4). Dedicated, labeled lumens and tubing reduce interruptions, unintended boluses, and incompatibility risk (Choice 5). If a vasopressor must begin before central access is available, current guidance supports short-term peripheral administration with close monitoring; a small distal hand vein is not the preferred site for sustained therapy (Choice 2). Prepare the next bag before the current bag empties because interruption can cause abrupt hypotension (Choice 6).
High-Alert Medications (ISMP) Carry heightened risk of significant harm when used in error. Examples: vasopressors (norepinephrine, epinephrine, vasopressin), insulin (continuous IV especially), heparin, opioids (PCA), neuromuscular blockers, chemotherapy, concentrated electrolytes (KCl, hypertonic saline).
Universal Safeguards 1. Smart pump with drug library + DERS 2. Two-RN independent verification at start, bag change, dose change 3. Standardized concentrations 4. Clear tubing labeling proximal + distal 5. Limited access; pharmacy preparation when feasible 6. Dedicated lumen per continuous high-alert infusion when possible
Vasopressor Specifics - Central line preferred for sustained therapy (peripheral only as brief bridge through proximal large vein with continuous monitoring) - Titrate to MAP target (typically ≥65 mmHg in septic shock) - Arterial line preferred for accuracy in shock - Plan bag changes with primed backup ready; avoid interruption (immediate severe hypotension) - Monitor for extravasation; phentolamine antidote for norepinephrine
Insulin Drip Specifics - Capillary glucose every 1 hr initially, then per protocol - Hypoglycemia surveillance (diaphoresis, tachycardia, altered mental status, glucose <70) - D50 ready - Coordinate with TPN, dextrose-containing fluids, and feedings - Transition to subcutaneous insulin with overlap when stable

High-Alert Medications (ISMP) — Medications that bear heightened risk of significant client harm when used in error. ISMP maintains the canonical list including vasopressors (norepinephrine, epinephrine, vasopressin), continuous IV insulin, heparin, neuromuscular blockers, chemotherapy, opioid PCA, concentrated electrolytes (KCl, hypertonic saline), and others. Institutional safeguards include smart pumps with drug library and dose-error reduction software, two-RN independent verification, standardized concentrations, and clear labeling.
Vasopressor Continuous Infusion Safety — Sustained vasopressor therapy (norepinephrine, epinephrine, vasopressin, phenylephrine) is administered via central venous catheter; peripheral access is acceptable only as a brief bridge through a proximal large vein with continuous monitoring for extravasation. Titrate to MAP target (typically ≥65 mmHg in septic shock) with continuous arterial pressure monitoring (arterial line preferred). Plan bag changes with a primed backup ready; brief interruption causes immediate severe hypotension. Phentolamine local infiltration is the antidote for norepinephrine extravasation.
Insulin Continuous Infusion Safety — Continuous IV regular insulin requires capillary blood glucose monitoring at least hourly while titrating, with protocol-based dose adjustment. Watch for hypoglycemia (diaphoresis, tachycardia, altered mental status, glucose <70 mg/dL); D50 should be readily available. Coordinate with concurrent TPN, dextrose-containing fluids, and feedings — interruption of these without insulin adjustment causes hypoglycemia. Transition to scheduled subcutaneous insulin with overlap when the client is stable to avoid rebound hyperglycemia.
