A nurse is caring for a client diagnosed with pneumonia and assesses labored breathing and copious tracheobronchial secretions. What priority action should the nurse encourage with the client?

A. Client develops ecchymosis at the venipuncture site. Minor bruising at venipuncture sites is a common and expected side effect of heparin therapy due to its anticoagulant effect. While the nurse should monitor for increased bruising, isolated ecchymosis at an IV site does not necessarily indicate excessive anticoagulation or require immediate provider notification.
B. PTT 70 seconds (control 25-40). Heparin therapy is adjusted based on the activated partial thromboplastin time (aPTT). The therapeutic range is typically 1.5 to 2.5 times the control value, which in this case would be approximately 60-100 seconds. A PTT of 70 seconds is within the therapeutic range, so it does not require urgent intervention.
C. Client develops hematuria. Hematuria is a sign of potential excessive anticoagulation or internal bleeding, which can be a serious complication of heparin therapy. This finding suggests that the client's coagulation status may need immediate reassessment, and the heparin infusion may require adjustment or reversal with protamine sulfate if necessary. The healthcare provider should be notified promptly.
D. Order for Coumadin 2.5 mg to begin today. It is common practice to start warfarin (Coumadin) while a client is on heparin therapy because warfarin takes several days to reach therapeutic levels. Heparin is typically continued until the INR reaches a therapeutic range. Therefore, this order does not require provider notification.

• Clostridium difficile infection is likely because the client has pneumonia and is receiving ceftriaxone, an antibiotic known to disrupt gut flora and cause opportunistic infections like C. difficile. The presence of frequent, liquid, foul-smelling stools further supports this diagnosis.
• Myocardial infarction is unlikely because while the client has chest pain, it is pleuritic and related to inspiration rather than the typical crushing, non-pleuritic chest pain seen in an MI. There is no mention of radiating pain, diaphoresis, or hemodynamic instability.
• Pulmonary edema is unlikely since it typically presents with dyspnea, crackles throughout the lung fields, pink frothy sputum, and signs of fluid overload such as peripheral edema and weight gain. The client’s symptoms do not align with this condition.
• Pulmonary embolism is also unlikely, as it presents with sudden-onset dyspnea, pleuritic chest pain, tachycardia, and often calf swelling or a history of deep vein thrombosis. The client lacks the risk factors and clinical signs of PE.
• Placing the client on contact precautions is necessary because C. difficile is highly contagious and spreads through the fecal-oral route. Gloves and gowns should be used to prevent transmission.
• Obtaining a stool culture is necessary to confirm the presence of C. difficile toxins in the stool, which is essential for accurate diagnosis and treatment.
• Requesting a prescription for an anticoagulant is not necessary because the client does not show any signs of thromboembolic disease such as deep vein thrombosis or pulmonary embolism. Anticoagulation could increase the risk of bleeding in the gastrointestinal tract, which would worsen the diarrhea.
• Requesting a prescription for a diuretic is not needed because the client is more likely to be dehydrated due to diarrhea. Diuretics would exacerbate fluid loss and electrolyte imbalances.
• Restricting fluids is not appropriate because dehydration is a major concern with C. difficile infection. Instead, fluid intake should be encouraged to prevent complications from excessive fluid loss.
• Level of consciousness should be monitored because severe dehydration and electrolyte imbalances can lead to confusion, weakness, and altered mental status. While altered mental status can occur with severe dehydration or sepsis, it is not the primary concern at this stage.
• Potassium level should be monitored because diarrhea can cause significant potassium loss, leading to hypokalemia, which can result in muscle weakness, cardiac arrhythmias, and fatigue.
• Urine output is not the most specific parameter for monitoring C. difficile infection. While dehydration is a concern, tracking electrolyte levels and neurological status is more critical.
• Calf swelling is not relevant since the client does not have signs or risk factors for deep vein thrombosis or pulmonary embolism.
• Weight: C. difficile infection can cause significant fluid loss due to persistent diarrhea, leading to dehydration and weight loss. Tracking daily weight helps assess hydration status and the effectiveness of fluid replacement therapy.
