A nurse is caring for a client who has respiratory acidosis. Which of the following pH levels should the nurse expect?
pH 7.48
pH 7.50
pH 7.31
pH 7.39
The Correct Answer is C
A. pH 7.48:
A pH of 7.48 indicates alkalosis, not acidosis. Respiratory acidosis is characterized by a pH below the normal range (7.35-7.45).
B. pH 7.50:
Similar to choice A, a pH of 7.50 indicates alkalosis, not acidosis.
C. pH 7.31:
This pH value falls below the normal range (7.35-7.45), indicating acidemia. In respiratory acidosis, there is an increase in the partial pressure of carbon dioxide (PaCO2) in the blood, leading to an accumulation of carbonic acid and a decrease in pH.
D. pH 7.39:
A pH of 7.39 falls within the normal range (7.35-7.45), indicating a normal acid-base balance. It does not indicate acidosis.

Correct Answer is B
Explanation
A. Root cause analysis:
Root cause analysis is a method used to identify the underlying causes of adverse events or errors. While it is important for quality improvement and risk management, it does not specifically involve using research and scientific data to guide clinical decision-making in client care.
B. Evidence-based practice:
Evidence-based practice (EBP) involves integrating the best available evidence from research studies with clinical expertise and patient preferences to guide decision-making in client care. By utilizing research and scientific data, nurses can identify effective interventions and strategies to improve client outcomes.
C. Benchmarking:
Benchmarking involves comparing performance metrics or outcomes against standards or best practices. While benchmarking can inform quality improvement efforts, it does not directly involve using research and scientific data to guide clinical decision-making.
D. Standardization:
Standardization involves implementing consistent processes or protocols to improve quality and safety. While standardization is important for ensuring consistency in care delivery, it does not necessarily rely on research and scientific data to inform clinical decision-making as evidence-based practice does.
Correct Answer is B
Explanation
A. Arrange referral for family therapy to deal with home stressors:
While family therapy may be beneficial in addressing underlying issues, suspected abuse must be reported promptly to protect the client's safety. Referral for family therapy can be considered as part of a comprehensive intervention plan but should not delay reporting of suspected abuse.
B. Follow the agency's guidelines for reporting suspected abuse:
Reporting suspected abuse is the first priority when there are concerns about a client's safety. Following the agency's guidelines ensures that the appropriate authorities are notified and that the client receives the necessary protection and support.
C. Check the bruises at the next visit to the client's home:
Delaying action and waiting until the next visit to check the bruises could put the client at further risk of harm. Suspected abuse requires immediate attention, and the nurse should follow established protocols for reporting and intervening in such situations.
D. Institute more frequent visits to the client's home:
While more frequent visits may allow for closer monitoring of the client's condition, suspected abuse should be addressed immediately through appropriate reporting channels. Increasing visit frequency alone may not adequately address the safety concerns and may delay necessary intervention.
