The healthcare provider prescribes a 5% dextrose injection 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 [3.5 to 5.0 mEq/L (3.5 to 5.0 mmol/L)]

Glucose [74 to 106 mg/dL (4.1 to 5.9 mmol/L)]

Choice A Reason: Hypoglycemia refers to low blood sugar levels, typically below 70 mg/dL (3.9 mmol/L). The client’s fasting blood glucose level is 122 mg/dL (6.8 mmol/L), which is above the normal range, thus ruling out hypoglycemia.

Choice B Reason: Diabetes mellitus is diagnosed when the fasting blood glucose level is 126 mg/dL (7 mmol/L) or higher on two separate tests1. The client’s level is slightly below this threshold, suggesting that he does not currently have diabetes mellitus but is at risk.

Choice C Reason: Prediabetes is indicated by a fasting blood glucose level of 100 to 125 mg/dL (5.6 to 6.9 mmol/L)1. The client’s level falls within this range, indicating that he has higher than normal blood glucose levels but not high enough to be classified as diabetes, hence prediabetes.

Choice D Reason: Gestational diabetes occurs during pregnancy and is not applicable to this male client.

Option i Reason: Fatty liver disease is not directly indicated by the laboratory results provided and is typically associated with elevated liver enzymes and imaging findings.

Option ii Reason: Occupational factors are not directly related to the fasting blood glucose levels.

Option iii Reason: Lack of insulin production is a characteristic of type 1 diabetes, which is not indicated by the client’s fasting blood glucose level alone.

Option iv Reason: Impaired glucose tolerance is a condition where blood glucose levels are higher than normal but not high enough to be classified as diabetes. It is a characteristic of prediabetes and is indicated by the client’s fasting blood glucose level.

Choice A reason: Asking the client to describe the pain is essential as it provides subjective information about the pain's quality, intensity, and impact on daily activities, which is crucial for assessing osteoarthritis pain.

Choice B reason: Observing body language and movement can offer insights into the pain's impact on function, but it does not replace the client's verbal description of the pain experience.

Choice C reason: Identifying effective pain relief measures is part of managing osteoarthritis but does not directly assess the quality of the client's knee pain.

Choice D reason: Providing a numeric pain scale is a method to quantify pain intensity but may not fully capture the quality or characteristics of the pain.
