This question tests focused data collection and reporting skills in allergic reaction assessment. The key priority is recognizing signs of anaphylaxis requiring immediate intervention. Swelling of the lips (B) indicates angioedema, which can progress rapidly to airway obstruction and is a medical emergency, especially with the respiratory rate of 22/min and oxygen saturation of 93%. While itching (A) is concerning, it's less severe than angioedema, childhood rash history (C) is already documented, and blood pressure (D) remains stable. The decision-making principle is that signs of airway involvement in allergic reactions require immediate reporting and intervention. When documenting allergic reactions, always prioritize findings that indicate progression to anaphylaxis, particularly facial or airway swelling.

This question tests focused data collection and reporting skills in identifying critical electrolyte imbalances. The key priority is recognizing dangerously low potassium levels in a client taking loop diuretics. The potassium level of 2.9 mEq/L (C) is critically low and requires immediate reporting because it can cause life-threatening cardiac arrhythmias, especially in a client with heart failure. The sodium level (A) is normal, creatinine (B) is within normal limits, and blood pressure (D) is adequately controlled. The decision-making principle is that critical lab values that can cause immediate cardiac complications take priority over stable findings. When reviewing lab results, always identify values that fall outside the critical range first, particularly electrolytes that affect cardiac function.

A firm, distended abdomen after abdominal surgery can indicate internal hemorrhage or peritonitis, which are life-threatening complications requiring immediate intervention. Absent bowel sounds are expected for up to 24-48 hours post-operatively due to anesthesia and bowel manipulation. Pain rated as 5/10 is expected after major surgery and should be managed with prescribed analgesics. Serosanguineous drainage is a normal finding on a surgical dressing.

The therapeutic INR for a client on warfarin for atrial fibrillation is typically 2.0 to 3.0. An INR of 5.2 is critically high and indicates an excessive anticoagulant effect, placing the client at a significant risk for bleeding. This finding must be reported immediately. The platelet count, PT (non-standardized), and hemoglobin values are within normal limits.

Pink, frothy sputum is a hallmark sign of acute pulmonary edema, a life-threatening complication of heart failure. This indicates fluid is filling the alveoli and requires immediate intervention. While fatigue, adequate urine output, and peripheral edema are common findings in heart failure, they do not signify the same level of acute danger as pink, frothy sputum.

Continuous, vigorous bubbling in the water seal chamber indicates a large air leak in the system or from the client, which is an abnormal and potentially serious finding. Occasional bubbling with coughing (intermittent) and tidaling (rising and falling of water) are normal findings. Sanguineous drainage of 50 mL/hr is within the expected range post-thoracotomy.

An expanding hematoma at the femoral insertion site indicates active bleeding, which can lead to significant blood loss and hemodynamic instability. This is a critical finding that requires immediate intervention. A small amount of blood, mild tenderness, and a capillary refill of 3 seconds (which is borderline but not critically delayed) are less urgent findings.

In an older adult, new onset of confusion or agitation is often the earliest sign of hypoxia or worsening infection. This change in mental status is a critical finding that must be reported immediately. The other findings (productive cough, acceptable oxygen saturation, and low-grade fever) are expected findings for a client with pneumonia.

The combination of hypertension (with a widening pulse pressure), bradycardia, and decreased respirations constitutes Cushing's triad, a late and ominous sign of increased intracranial pressure (ICP). This indicates pressure on the brainstem and is a neurological emergency that must be reported immediately. The other vital sign sets represent potential hypovolemia (C), normal ranges (D), or mild tachycardia/tachypnea (A), which are less critical in this context.

Visual disturbances, such as seeing yellow-green halos, are a classic sign of digoxin toxicity. This finding requires withholding the dose and notifying the RN for further assessment and orders. An apical pulse of 64 is acceptable (usually held for <60), the blood pressure is normal, and the potassium level is within the normal range.
