The nurse is caring for a client who has been diagnosed with an exacerbation of a progressive neurologic disease. The nurse recognizes that the client understands palliative care when the client states:

A. Vomiting results in loss of hydrochloric acid (HCl) from the stomach, leading to a loss of chloride ions (Cl-) and hydrogen ions (H+) from the body. This loss of hydrogen ions can result in an accumulation of bicarbonate ions (HCO3-) relative to hydrogen ions, leading to metabolic alkalosis. Therefore, this client is at risk for developing metabolic alkalosis due to prolonged vomiting.
B. Client who has had diarrhea for the past 24 hours: Diarrhea leads to loss of bicarbonate ions (HCO3-) from the body along with fluid and electrolytes. However, metabolic alkalosis is less likely to occur with diarrhea alone because the loss of bicarbonate ions is usually balanced by the loss of chloride ions (Cl-) and hydrogen ions (H+). Therefore, while diarrhea can lead to metabolic acidosis in some cases, it is less likely to cause metabolic alkalosis.
C. Client who has overdosed on heroin: Heroin overdose is not directly associated with metabolic alkalosis. In the context of heroin overdose, respiratory depression leading to respiratory acidosis is a more immediate concern. Therefore, this client is not at risk for developing metabolic alkalosis due to heroin overdose.
D. Client who is admitted with an asthma exacerbation: Asthma exacerbation can lead to respiratory alkalosis due to hyperventilation and excessive elimination of carbon dioxide (CO2) from the body. However, metabolic alkalosis is not a typical consequence of asthma exacerbation alone. Therefore, while this client may experience respiratory alkalosis, they are not at risk for developing metabolic alkalosis solely due to asthma exacerbation.

C. Providing relief from pain and other distressing symptoms is a fundamental aspect of hospice care. The nurse should assess the client's pain level and other symptoms such as dyspnea, coughing, and restlessness, and intervene accordingly. This may involve administering analgesics, antitussives, or other medications as appropriate to alleviate discomfort and promote comfort and quality of life.
D. Placing the bed in semi-Fowler's position (with the head of the bed elevated) can help improve respiratory mechanics, ease breathing, and reduce respiratory distress in clients experiencing dyspnea. This position allows for better lung expansion and can facilitate the drainage of respiratory secretions, thereby promoting comfort and alleviating symptoms. This intervention does not typically require a medical order and can be implemented by the nurse based on clinical assessment.
A. Calling for transportation to the hospital may not be necessary or appropriate in this situation, especially considering that the client is under hospice care and experiencing changes in respiratory status and restlessness, which could be indicative of end-of-life processes. Hospice care focuses on providing comfort and symptom management in the home setting, and hospitalization may not align with the client's goals of care at this stage.
B. Initiating low-flow oxygen per nasal cannula may be appropriate to provide comfort and relieve hypoxia if the client is experiencing respiratory distress. However, this intervention would typically require a medical order, as oxygen therapy should be prescribed based on assessment findings and clinical indications.
E. Administering anti-anxiety medications may be considered if the client is experiencing significant anxiety or agitation that is distressing and impacting their comfort. However, the decision to administer anti-anxiety medications should be based on thorough assessment and consideration of the client's overall condition, goals of care, and potential risks and benefits. This intervention would typically require a medical order.
