A client presents to the emergency department because he is coughing up blood. His wife reports that the client has cirrhosis of the liver and increased confusion. How should the nurse perform an abdominal assessment?

Rationale for correct choices:

• Encephalopathy: The client has a history of cirrhosis and is presenting with decreased level of consciousness, lethargy, slurred speech, impaired concentration, and altered sleep patterns (sleeping during the day and awake at night). These findings are classic manifestations of hepatic encephalopathy, a serious complication of advanced liver disease caused by accumulation of neurotoxins in the bloodstream.

• Ammonia level: The ammonia level is markedly elevated at 250 mcg/dL (normal 10–80 mcg/dL). In cirrhosis, the liver cannot effectively convert ammonia to urea for excretion. The buildup of ammonia crosses the blood-brain barrier, resulting in neurological symptoms such as confusion, decreased LOC, and altered cognition. This lab finding directly explains the client’s neurological presentation.

Rationale for incorrect choices:

• Diabetic ketoacidosis: Although the client has type 2 diabetes mellitus, the glucose level is 148 mg/dL, which is elevated but not high enough to indicate DKA. There is no evidence of severe hyperglycemia, metabolic acidosis, or ketones.

• Malnutrition: The albumin level is low (2.9 g/dL), which is common in cirrhosis, but malnutrition does not directly explain the acute neurological deterioration.

• Acute kidney disease: The creatinine (0.8 mg/dL) and BUN (18 mg/dL) are within normal limits, indicating adequate renal function.

• Dehydration: Sodium and potassium levels are within normal range, and there is no evidence of hemoconcentration. Additionally, the client has ascites and edema, indicating fluid retention rather than dehydration.

• Creatinine level: Normal, does not indicate kidney impairment.

• Sodium level: Within normal range, does not explain neurological changes.

• Potassium level: Within normal range.

• Glucose level: Mildly elevated but not severe enough to cause altered level of consciousness in this context.

Rationale:

A. In a mass-casualty or field triage situation, time is critical, and the priority is to rapidly identify life-threatening injuries and categorize patients for treatment, rather than performing a detailed head-to-toe assessment on every victim. Complete assessments are performed later once patients are stabilized or brought to definitive care. Spending time on a full assessment in the field could delay care for more critical victims.

B. While notifying the receiving hospital is an important step in disaster response, it is not the immediate priority during initial triage. The nurse’s first responsibility in the field is to assess and categorize patients to determine treatment priority based on the severity of injuries. Communication with the hospital is secondary and occurs after rapid triage.

C. In emergency and disaster situations, consent is implied for urgent or life-threatening injuries. Waiting to locate parents before providing care could delay treatment and put the child at unnecessary risk. Parental consent can be obtained later if needed once the child is stabilized.

D. The child has an open femur fracture, which is a serious injury that requires prompt care but is not immediately life-threatening if airway, breathing, and circulation are stable. In field triage, this type of injury is categorized as yellow (urgent/delayed). Yellow-tagged patients need care after immediate life-threatening cases (red tag) are stabilized, but before minor injuries (green tag). The tag communicates the priority
