A patient in ICU for a diagnosis of stage IV wound to the sacrum goes into Septic Shock. The nurse receives an order to begin a norepinephrine infusion 18 mL/hr. The patient weighs 158 lbs. The norepinephrine is supplied in a concentration of 4mg in 250 ml of D5W.

What is the norepinephrine dose in mcg/kg/min? Place your answer to thousandths.

A. Flush the primary line with saline before and after administering the Protonix: Protonix (pantoprazole) IV push can interact with certain solutions, and compatibility with potassium-containing IV fluids is limited. Flushing the line before and after ensures that the drug is delivered without mixing directly with D5 ½ NS with KCl, preventing precipitation, chemical reactions, or irritation to the vein.

B. Hold the Protonix until the physician rounds: Delaying administration unnecessarily could compromise patient care, particularly if the Protonix is ordered to prevent stress ulcers or gastrointestinal bleeding. The solution is not to withhold the medication but to follow proper IV administration precautions.

C. Call the physician to request an alternate route to administer the Protonix: While alternative routes such as a separate IV line could be used, flushing the existing line is an established and safe procedure. Calling the physician is not immediately necessary unless line access issues prevent safe administration.

D. Administer the Protonix through the primary line at the "Y" port: Administering the IVP medication directly into the primary line without flushing could allow it to mix with the D5 ½ NS with KCl, which may cause incompatibility reactions. Direct injection without flushing increases the risk of precipitation and vein irritation.

A. Syndrome of inappropriate secretions of antidiuretic hormone (SIADH): SIADH is characterized by water retention, hyponatremia, and low serum osmolality. While it can occur in cancer patients, it does not typically cause facial and neck swelling or distended chest veins, making it unlikely in this scenario.

B. Disseminated intravascular coagulation (DIC): DIC is a systemic coagulopathy leading to both thrombosis and bleeding. Clinical manifestations include petechiae, ecchymoses, and bleeding, not venous distention or facial edema. DIC does not explain the localized obstruction of venous return.

C. Pericardial effusion/tamponade (PE/T): Cardiac tamponade causes jugular venous distention, hypotension, and muffled heart sounds (Beck’s triad). While there may be venous congestion, the edema is usually generalized, not limited to the face, neck, and upper chest, and periorbital edema is less typical.

D. Superior vena cava syndrome (SVC): SVC syndrome results from obstruction of the superior vena cava, often due to malignancy compressing the vessel. This obstruction impairs venous return from the head, neck, and upper extremities, leading to facial and periorbital edema, neck swelling, and distended chest veins. It is an oncologic emergency requiring prompt recognition and intervention.
