A nurse is taking a class about patient safety. The nurse should recognize that which of the following statements is true regarding patient safety and prevention of harm?

• 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.

A. Respond to ventilator alarms: While it is crucial to respond to ventilator alarms promptly to ensure the client’s safety and adequate ventilation, this action is not the highest priority in relation to the use of neuromuscular blockers. The use of neuromuscular blockade requires a broader focus on the patient's overall care and safety.
B. Report the absence of spontaneous respirations: Reporting the absence of spontaneous respirations is important, as neuromuscular blockers can cause paralysis of the respiratory muscles. However, the focus should be on maintaining the client's safety and comfort while they are on mechanical ventilation, rather than just reporting findings.
C. Provide passive range-of-motion exercises: This is the priority action when caring for a client receiving neuromuscular blockers. Since the client cannot move voluntarily due to the effects of the neuromuscular blockade, passive range-of-motion exercises are essential to prevent complications such as contractures and muscle atrophy. This intervention helps maintain joint mobility and circulation, which is critical in patients who are mechanically ventilated for an extended period.
D. Encourage the client to attempt to breathe on their own: Encouraging the client to breathe on their own is not appropriate when they are receiving neuromuscular blockade, as their respiratory muscles are paralyzed. Instead, the focus should be on ensuring that the mechanical ventilation settings are adequate to provide proper oxygenation and ventilation while the client cannot initiate breaths independently. This action could lead to respiratory distress if attempted while under neuromuscular blockade.
