A client is admitted to the intensive care unit with multisystem organ dysfunction syndrome (MODS). The client is restless, febrile, and nauseated. Insulin is infusing at 5 units/hour per protocol to keep blood glucose less than 150 mg/dL (8.3 mmol/L). Dopamine is infusing at 5 mcg/kg/minute per protocol to keep mean arterial pressure (MAP) greater than 65 mm Hg. Serum blood glucose is 160 mg/dL and MAP is 66 mm Hg. The client is receiving oxygen at 50% via face mask and has an oxygen saturation of 92%. Which intervention should the nurse implement?

Reference Range:

Glucose [74 to 106 mg/dL (4.1 to 5.9 mmol/L)]

Administer famotidine 20 mg IV.

Titrate insulin infusion by 1 unit/hour.

Increase dopamine 2 mcg/kg.

Raise oxygen by 10 percent.

Answer and Explanation

The Correct Answer is B

A. Administer famotidine 20 mg IV. Famotidine is a histamine-2 receptor antagonist used for stress ulcer prophylaxis in critically ill patients. While this medication may be beneficial, it is not the priority intervention based on the insulin protocol and the client's blood glucose level.
B. Titrate insulin infusion by 1 unit/hour. The client’s blood glucose is 160 mg/dL, which falls within the 150–199 mg/dL range according to the insulin protocol. The protocol directs the nurse to increase the insulin drip rate by 1 unit/hour to maintain blood glucose levels below 150 mg/dL. This is the most immediate and appropriate action.
C. Increase dopamine 2 mcg/kg. The client’s MAP is 66 mmHg, which meets the protocol goal of keeping MAP >65 mmHg. There is no indication for increasing dopamine at this time, as the blood pressure is already within the target range.
D. Raise oxygen by 10 percent. The client is on 50% FiO₂ via a face mask with an oxygen saturation of 92%, which is adequate oxygenation for a critically ill patient. Increasing FiO₂ unnecessarily may contribute to oxygen toxicity and is not required based on current oxygenation status.

Correct Answer is A

Explanation

A. Provide a bedside table for the client to lean across. Clients with acute pancreatitis often experience severe epigastric pain that radiates to the back. Leaning forward helps reduce pressure on the inflamed pancreas and relieves pain by minimizing peritoneal irritation. Providing a bedside table allows the client to rest in a comfortable, supported position, improving pain management without additional interventions.
B. Place bed in the reverse Trendelenburg position. Reverse Trendelenburg elevates the head and lowers the feet, which does not specifically relieve pain associated with pancreatitis. The client instinctively leans forward for relief, and adjusting the bed position would not provide the same benefit. This intervention does not directly address the underlying cause of discomfort.
C. Encourage bed rest until analgesic takes effect. Although pain control is essential, keeping the client in a supine or bedrest position can increase abdominal pressure and worsen discomfort. Allowing the client to assume a comfortable position enhances the effectiveness of analgesics and prevents unnecessary distress. Pain relief strategies should focus on both pharmacologic and positioning interventions.
D. Raise the head of the bed to a 90-degree angle. Elevating the head of the bed can improve breathing and reduce reflux, but it does not provide the same pressure relief as leaning forward. Sitting upright without forward support does not effectively relieve peritoneal irritation from pancreatic inflammation. Providing a bedside table supports proper positioning and enhances comfort.

A. Muffled heart tones. B. Bilateral sonorous wheezes. C. Widening pulse pressure. D. Decreased urinary output.

Correct Answer is A

Explanation

A. Muffled heart tones. Muffled heart tones in a client with blunt chest trauma are a key sign of cardiac tamponade, a life-threatening emergency where blood or fluid accumulates in the pericardial sac, preventing proper cardiac filling. This condition is part of Beck's triad (muffled heart tones, hypotension, and jugular vein distention) and requires immediate intervention, such as pericardiocentesis, to relieve pressure on the heart.
B. Bilateral sonorous wheezes. While wheezing indicates airway obstruction or bronchospasm, it is not as immediately life-threatening as cardiac tamponade. The nurse should continue monitoring and consider interventions like bronchodilators, but the priority is addressing muffled heart tones.
C. Widening pulse pressure. A widening pulse pressure (increased difference between systolic and diastolic BP) is typically associated with increased intracranial pressure (ICP) rather than blunt chest trauma. In chest trauma, a narrowing pulse pressure (e.g., in hypovolemic or obstructive shock) would be a greater concern.
D. Decreased urinary output. Reduced urine output may indicate shock or poor perfusion, but it is not the most urgent finding compared to muffled heart tones, which suggest impending cardiovascular collapse. While decreased urinary output should be addressed, cardiac tamponade takes priority due to the immediate risk of death.
