A college health nurse interprets the peak expiratory flow rate for student who has asthma and finds that the student is in the yellow zone of his asthma action plan. The nurse should base her actions on which of the following information? (Select all that apply.)

A. Cultural differences. While cultural beliefs may influence end-of-life decisions, the primary issue in this scenario is not cultural misunderstanding but rather the conflict between the client’s documented wishes and the family's demands. Cultural differences typically pertain to variations in values, traditions, or beliefs, rather than legal and ethical dilemmas regarding patient autonomy.
B. Ethical conflict. The nurse is experiencing moral distress due to a conflict between ethical principles—specifically, the principle of patient autonomy (respecting the client’s right to make their own healthcare decisions) and beneficence (providing care that benefits the client). The client’s living will, a legally binding document, states Do Not Resuscitate (DNR), yet the children are insisting on full resuscitation. The nurse’s distress arises from witnessing actions that contradict the client’s wishes and ethical nursing responsibilities.
C. Competition between groups. There is no indication that different groups, such as healthcare teams or family members, are competing for resources or control. The conflict stems from an ethical dilemma rather than rivalry or organizational disputes.
D. Scarcity, safety, and security. This situation does not involve limited resources, threats to safety, or security concerns. The distress is rooted in the ethical dilemma of honoring the client’s advance directive versus the family’s insistence on aggressive resuscitation measures.

• 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.
