A nurse on a medical unit is reviewing the laboratory reports for a client. Which of the following laboratory values is the priority to report to the provider?
Potassium level 3 mEq/L.
BUN 9.5 mg/dl
Creatinine 0.4 mg/dl
Sodium 135 mEq/L
The Correct Answer is A
A) Potassium level 3 mEq/L:
A potassium level of 3 mEq/L is below the normal range (which is typically 3.5-5.0 mEq/L) and represents hypokalemia. Potassium is crucial for normal muscle and nerve function, including cardiac function. Low potassium levels can lead to dangerous arrhythmias, muscle weakness, and cardiac arrest if not addressed promptly. This is the priority value because hypokalemia can be life-threatening and requires immediate attention from the healthcare provider to correct the imbalance.
B) BUN 9.5 mg/dl:
A BUN (blood urea nitrogen) level of 9.5 mg/dL is within the normal reference range for most adults (typically 7-20 mg/dL). While an abnormal BUN level could indicate kidney dysfunction or dehydration, this value is not immediately concerning and does not represent a critical finding that requires urgent attention.
C) Creatinine 0.4 mg/dl:
A creatinine level of 0.4 mg/dL is below the normal range (usually around 0.6-1.2 mg/dL), which might indicate low muscle mass or a transient decrease in kidney function. However, a low creatinine level is generally not as urgent or concerning as an elevated level, and it does not typically require immediate intervention
D) Sodium 135 mEq/L:
A sodium level of 135 mEq/L is slightly below the normal range (135-145 mEq/L), indicating mild hyponatremia. Although this can be concerning if the drop is acute or symptomatic (e.g., causing confusion, seizures, or lethargy), a mild decrease in sodium is not immediately life-threatening unless it worsens rapidly.

Correct Answer is D
Explanation
A) Teach the use of an incentive spirometer to a postoperative client:
Teaching a patient how to use an incentive spirometer involves assessment, education, and clinical judgment. This task requires the nurse's expertise to ensure that the patient understands how to use the device correctly and to assess for any potential complications, such as inadequate lung expansion.
B) Irrigate and perform a dressing change for a client who has a pressure injury wound:
Irrigating and changing the dressing of a pressure injury involves clinical judgment, the need for sterile technique, and the assessment of the wound. These tasks should be performed by a registered nurse (RN), who can assess the condition of the wound, evaluate for signs of infection, and make decisions regarding further care.
C) Administer oral PRN pain medication to a client who has arthritis:
Administering PRN pain medication requires assessment of the patient's pain level, consideration of the medication’s effects, and clinical judgment regarding the appropriateness of the medication. This is a nursing responsibility because it involves both medication management and the evaluation of therapeutic effects.
D) Obtain a daily weight on a client who has heart failure:
Obtaining a daily weight is a task that can be safely delegated to an assistive personnel (AP). Weight is an important measurement for monitoring fluid status, especially in clients with heart failure. The AP can accurately weigh the client, ensuring that the same scale and conditions (such as time of day, after the patient has voided) are followed each time.
Correct Answer is C
Explanation
A) SOAP documentation:
SOAP (Subjective, Objective, Assessment, Plan) documentation is a method used for organizing and documenting client information. It focuses on both subjective and objective data, as well as the assessment and plan. While SOAP helps structure the documentation of patient conditions and interventions, it does not specifically focus on documenting only unexpected findings. It is a more comprehensive approach that includes normal and abnormal findings, not just the unexpected ones.
B) Focus charting (DAR):
Focus charting (DAR) is based on a client-centered approach and uses the components of Data, Action, and Response. It is a way of documenting observations and interventions, particularly in relation to specific patient problems or conditions. Focus charting is more about the care provided, responses to interventions, and client outcomes. While it may include unexpected findings, it doesn’t limit documentation exclusively to abnormal or unexpected events.
C) Charting by exception (CBE):
Charting by exception (CBE) is a documentation method that focuses on recording only the significant deviations from the norm. It emphasizes noting any abnormal or unexpected findings, and everything that is normal is assumed to be within expected limits and not documented. This method reduces the amount of documentation by excluding routine information and only highlighting significant, unexpected findings. Therefore, CBE is the correct answer in this scenario, as it involves documenting only unexpected or abnormal findings related to the client's condition.
D) Problem-oriented medical record (POMR):
POMR is a method of documentation that organizes client care around specific problems or diagnoses. It includes the identification of problems, interventions, and outcomes. While POMR focuses on client problems and plans of care, it does not specifically focus on documenting only unexpected findings. It may include both normal and abnormal findings related to each identified problem.
