After intubating a client, correct placement of the endotracheal tube (ETT) is confirmed with a chest x-ray. Which intervention should the nurse implement to ensure that the ETT placement is maintained?

Answer:

Potential Condition:

Acute Adrenal Crisis

• The client has a history of Addison’s disease (chronic steroid use) and recent illness with vomiting, leading to decreased oral intake and medication noncompliance.
• Symptoms such as hypotension (80/50 mmHg), tachycardia (115 bpm), confusion, nausea, vomiting, and abdominal pain are classic signs of acute adrenal insufficiency.

Actions to Take:

Bolus Intravenous Fluids

• Fluid resuscitation with 0.9% normal saline is critical to restore intravascular volume and correct hypotension due to adrenal insufficiency.

Check Blood Glucose

• Hypoglycemia is a common complication of adrenal crisis due to cortisol deficiency, requiring close monitoring and possible glucose administration.

Parameters to Monitor:

Blood Pressure

• Hypotension is a hallmark of adrenal crisis and must be monitored closely to assess response to fluid resuscitation and steroid therapy.

Electrolytes

• Clients with adrenal crisis often have hyponatremia and hyperkalemia due to aldosterone deficiency, requiring frequent electrolyte monitoring.

Incorrect Choices:

Potential Conditions:

• Ketoacidosis: More common in diabetes, presents with high blood glucose and ketonuria.
• Diabetes Insipidus: Causes polyuria and dehydration but lacks hypotension and hyperkalemia.
• Myxedema: Linked to hypothyroidism, causing bradycardia and hypothermia, not hypotension and hyperkalemia.

Actions to Take:

• Hold hydrocortisone dose: Steroid replacement is necessary, not withholding it.
• Collect urine for a urinalysis: Not a priority; adrenal crisis is diagnosed via history, symptoms, and labs.
• Change intravenous fluids to 0.45%: Hypotension requires 0.9% normal saline, not hypotonic fluids.

Parameters to Monitor:

• Urine output: Useful but less critical than blood pressure and electrolytes in adrenal crisis.
• Thyroid stimulating hormone: Relevant for hypothyroidism, not adrenal insufficiency.
• Heart rate: Tachycardia is expected but is not the most critical indicator of improvement.

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.
