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 C
Explanation
A) Notify the facility’s ethics committee:
While it may be relevant to involve an ethics committee in certain complex situations, such as when there are concerns about patient autonomy or ethical decision-making, the refusal of a medication by a client is generally a standard issue that does not immediately require ethics consultation.
B) Return the opened medication in the medication cart:
Returning an opened unit-dose medication to the cart is not appropriate. Once a unit-dose medication is opened, it cannot be reused due to safety concerns (e.g., contamination, dosage errors). The opened medication should be disposed of properly according to the facility's policies for medication handling and disposal.
C) Report the incident to the provider:
The provider should be notified when a client refuses medication, especially if the medication is essential for the client’s treatment or health condition. It is important for the nurse to document the refusal and inform the provider so that appropriate follow-up can be arranged, including possible reassessment of the treatment plan, alternative medications, or further education for the client.
D) Fill out an incident report:
An incident report is typically completed for situations that involve safety issues, errors, or accidents that may affect patient safety or quality of care. While refusal of medication is an important event, it does not generally require an incident report unless it involves an unusual or dangerous situation, such as a medication error or patient harm.
Correct Answer is C
Explanation
A) A client who has early dementia and awoke confused to their location this morning:
Confusion in a client with early dementia could indicate a range of possible causes, such as infections, medication side effects, or changes in routine. However, while this warrants investigation, confusion alone does not represent an immediate life-threatening situation according to the ABCDE priority framework. The focus is on managing airway, breathing, circulation, and disability issues first.
B) A client who is scheduled for discharge and has a 38.4°C (101.1°F) temperature this morning:
A fever may indicate infection, which would require further assessment and potentially treatment. While this is a concern, it does not immediately threaten the client's airway, breathing, or circulation. Since the client is not in an acute crisis and is scheduled for discharge, this would be a lower priority compared to clients with more urgent issues like breathing problems or insufficient urine output.
C) A client who has pneumonia and has developed wheezing:
Wheezing indicates potential airway constriction, which could impair the client's breathing. Given that breathing difficulties are a primary concern in the ABCDE priority framework (Airway, Breathing, Circulation, Disability, and Exposure), this client requires immediate attention. Pneumonia combined with wheezing can signify a worsening respiratory condition, which poses an acute risk to the client's oxygenation and overall stability.
D) A client who is postoperative and has a urine output of 50 mL for the past 3 hours:
Oliguria (low urine output) postoperatively is concerning, as it may indicate kidney dysfunction, hypovolemia, or other complications. While it is an important issue that requires attention, it is not immediately life-threatening unless the client shows signs of worsening shock or kidney failure. However, given that this issue does not immediately affect the client’s airway or breathing, it is a lower priority than the client with pneumonia and wheezing.
