The healthcare provider prescribes 5% Dextrose Injection, USP with 20 units of regular insulin for a client with a serum potassium level of 6.0 mEq/L (6.0 mmol/L) and glucose level of 180 mg/dL (10.0 mmol/L). Which evaluation is most important for the nurse to include in this client's plan of care?

Reference Range

• Potassium [Reference Range: 3.5 to 5.0 mEq/L (3.5 to 5.0 mmol/L)]
• Glucose [Reference Range: 0 to 50 years: 74 to 106 mg/dL (4.1 to 5.9 mmol/L)]

The client's serum potassium level is elevated at 6.0 mEq/L (6.0 mmol/L), which is above the normal reference range of 3.5 to 5.0 mEq/L (3.5 to 5.0 mmol/L).

Hyperkalemia can have significant cardiac implications, including the potential for life-threatening dysrhythmias. Therefore, close monitoring of the serum potassium level is crucial to assess the effectiveness of interventions and ensure that potassium levels are within a safe range.

While monitoring glucose levels before and after meals is important for clients receiving insulin therapy, in this scenario, the primary concern is the elevated potassium level.

The nurse should prioritize frequent assessment of the serum potassium level to guide appropriate management and prevent complications associated with hyperkalemia.

Monitoring and documenting strict intake and output are important for assessing fluid balance and renal function, but in this case, the elevated potassium level takes precedence as it poses a more immediate risk to the client's well-being.

Obtaining a 12-lead electrocardiogram (ECG) daily may be indicated in some cases of hyperkalemia, as certain ECG changes can be associated with elevated potassium levels. However, the more critical aspect is monitoring the potassium level itself, as ECG changes can occur rapidly and may not always be detectable on a daily basis.

A) Correct- Viral meningitis is an inflammation of the meninges (the protective membranes surrounding the brain and spinal cord) caused by a viral infection. While it can be serious, it is generally less severe than bacterial meningitis. Monitoring the client's temperature is an important aspect of care, as changes in temperature can indicate the progression of the illness or the effectiveness of interventions. A temperature increase from 101°F to 102°F is a subtle change but may still require close monitoring and symptom management. The practical nurse (PN) is capable of monitoring vital signs, including temperature, and reporting any changes to the registered nurse (RN) or healthcare provider. It is within the PN's scope of practice to assess and report changes in vital signs and general condition. The other scenarios involve more complex clinical situations that may require the expertise of registered nurses.
B) Incorrect- Myxedema coma is a severe form of hypothyroidism and is considered a medical emergency. Managing and assessing a client with myxedema coma requires advanced assessment, critical thinking, and interventions that are typically within the scope of registered nurses.
C) Incorrect- Diabetic ketoacidosis (DKA) is a complex condition that requires frequent monitoring of blood glucose levels, electrolytes, vital signs, and assessment of the level of consciousness. The change in the Glasgow Coma Scale score indicates a neurological deterioration that requires immediate attention and intervention, making it suitable for a registered nurse.
D) Incorrect- A subdural hematoma is a serious neurological condition that requires close monitoring of vital signs and neurological status. The change in blood pressure indicates a potential change in intracranial pressure and should be managed by registered nurses with expertise in neurological care.
