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)]
Evaluate glucose levels before and after meals.
Assess the serum potassium level every 4 hours.
Monitor and document strict intake and output.
Obtain a 12-lead electrocardiogram daily.
The Correct Answer is B
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.

Correct Answer is D
Explanation
A pounding headache in a client with COPD may be a symptom of increased carbon dioxide (CO2) levels in the blood, known as hypercapnia. Hypercapnia can lead to vasodilation, resulting in headaches. In this situation, it is crucial to assess the client's blood pressure to determine if it is elevated, as this could be contributing to the headache.
Obtaining a manual blood pressure measurement allows for a more accurate assessment of the client's blood pressure compared to automated measurements. It is important to assess both systolic and diastolic blood pressures, as elevated blood pressure can worsen headaches and have other negative effects on the client's health.
Elevating the head of the bed no higher than 30 degrees is a general measure used to improve respiratory function in clients with COPD. However, in this specific situation, it may not directly address the pounding headache. Elevating the head of the bed can help reduce dyspnea and improve oxygenation, but it may not alleviate the headache caused by hypercapnia.
Affirming blood glucose levels are below 160 mg/dL (8.88 mmol/L) is not the primary concern in this case. While high blood glucose levels can have various effects on the body, including headaches, the priority is to assess the client's blood pressure due to the specific context of a COPD exacerbation.
Checking for a stat intravenous diuretic prescription is not necessary in response to the client's headache. Diuretics are typically used to remove excess fluid from the body and may not directly address the underlying cause of the headache in this situation.

Correct Answer is D
Explanation
A) Incorrect- Observing for swelling at the fracture site is important for assessing the client's musculoskeletal condition, but it is not the priority intervention in this situation. The absence of spontaneous respirations and palpable carotid pulse indicates cardiac arrest, and immediate intervention is needed.
B) Incorrect- Analyzing the cardiac rhythm in another lead is not the first priority when the client is in cardiac arrest. Cardiopulmonary resuscitation (CPR) should be initiated immediately to restore circulation.
C) Incorrect- Obtaining a 12-lead electrocardiogram is not the initial intervention in a client in cardiac arrest. CPR and defibrillation (if indicated) are the immediate actions to provide circulation and oxygenation to the vital organs.
D) Correct- The absence of spontaneous respirations and palpable carotid pulse indicates cardiac arrest. In this situation, immediate initiation of cardiopulmonary resuscitation (CPR) is critical to provide circulation and oxygenation to the vital organs. Chest compressions are the initial step to address cardiac arrest and ensure blood flow to the body.
