For an arterial blood gas (ABG) to have full compensation, which of the following statements is correct?
pCO2 and pHCO3 and pH are abnormal but the pa02 remains between 80-100 mmHg
arterial pH & pCO2 are abnormal but the pHCO3 is starting to change
pCO2, pHCO3 and pH have adjusted in expected range in 72 hours
arterial pH is between 7.35-7.45 and the pCO2 & pO2 are abnormal
The Correct Answer is C
C. Full compensation typically occurs within 2 to 3 days (approximately 72 hours) after the onset of an acid-base disturbance. During full compensation, the primary acid-base disorder (e.g., respiratory acidosis or alkalosis, metabolic acidosis or alkalosis) is still present, but the compensatory mechanisms have effectively brought the pH, pCO2, and bicarbonate (pHCO3) levels back towards normal range.
A. Full compensation occurs when both the primary disorder (respiratory or metabolic) and the compensatory mechanism (renal or respiratory) are functioning to return the pH towards normal. In this option, while the pO2 is within the normal range, the pH, pCO2, and bicarbonate (pHCO3) are all abnormal, indicating an ongoing imbalance.
B. Full compensation occurs when all components of the ABG are within or approaching normal range, indicating that the body's compensatory mechanisms have effectively counteracted the primary acid- base disturbance. In this option, the bicarbonate (pHCO3) is mentioned as starting to change, indicating incomplete compensation.
D. While the pH is within the normal range, both the pCO2 and pO2 are abnormal, indicating a primary respiratory disturbance. In the case of full compensation, the pH, pCO2, and bicarbonate (pHCO3) levels would all be within or approaching normal range, indicating that the compensatory mechanisms have effectively counteracted the primary acid-base disturbance.

Correct Answer is ["C","D"]
Explanation
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.
Correct Answer is ["A","C","D","E"]
Explanation
A. Documenting the type of solution provided for tube feeding is essential for accurate record-keeping and continuity of care. This includes specifying the name and composition of the enteral formula used, such as standard polymeric, high-protein, elemental, or specialized formulas for specific medical conditions or nutritional needs.
C. Documenting the client's tolerance of the tube feeding is crucial for monitoring their response to the enteral nutrition. This includes assessing for signs of intolerance, such as nausea, vomiting, abdominal pain, bloating, diarrhea, or aspiration. Documenting tolerance helps guide adjustments to the feeding regimen and ensures patient safety and comfort.
D. Documenting the amount of solution administered during the tube feeding is essential for accurately monitoring the client's intake and ensuring that nutritional goals are met. This includes recording the volume of formula administered, as well as any additional flushes or medications given through the feeding tube.
E. Documenting the duration of the tube feeding session provides important information about the timing and frequency of feedings. This includes recording the start and end times of the feeding, as well as any interruptions or adjustments made during the procedure. Documenting the duration helps ensure consistency in the feeding regimen and facilitates effective communication among healthcare providers.
B. Documenting the name of the physician who prescribed the tube is not necessary.
