A female college student comes to the school's health clinic reporting urinary frequency and burning with right lower back pain. Which intervention should the nurse implement first?

Choice A reason: Haemoglobin A1C of 6.2% is the best indication of long-term adherence to the prescribed diabetic regimen. The A1C test measures the average blood glucose levels over the past two to three months. A result of 6.2% indicates that the client has been maintaining good blood glucose control over this period, which reflects adherence to the regimen.

Choice B reason: Fasting plasma glucose of 189 mg/dL (10.49 mmol/L) is higher than the normal range. This result indicates poor short-term blood glucose control and suggests that the client may not be adhering to the prescribed regimen effectively.

Choice C reason: Postprandial plasma glucose of 225 mg/dL (12.49 mmol/L) is also higher than the recommended level for post-meal glucose. This result points to poor post-meal glucose control and suggests that the client may not be following their dietary or medication plan properly.

Choice D reason: High-density lipoprotein (HDL) of 40 mg/dL (1.03 mmol/L) is slightly below the recommended level for HDL cholesterol. While HDL is important for cardiovascular health, it is not a direct measure of blood glucose control or adherence to a diabetic regimen.

Choice A reason: The degree of skin elasticity is a measure often used to assess hydration status, especially in older adults. However, it does not provide direct information about the client's cardiac function or the cause of their current symptoms.

Choice B reason: The length of capillary refill is useful for assessing peripheral perfusion and overall circulatory status. While prolonged capillary refill can indicate poor perfusion, it does not provide specific information about heart rhythm or the cause of palpitations and faintness in a client with heart failure.

Choice C reason: The rhythm of the apical pulse is the most important assessment data to obtain in this scenario. The client's complaint of a fast-beating heart and feeling faint suggests a possible arrhythmia, which could be detected by assessing the rhythm of the apical pulse. This assessment can help identify irregular heartbeats, tachycardia, or other abnormalities that may require immediate intervention.

Choice D reason: The volume of pedal pulses can provide information about peripheral circulation, but it is not as crucial as assessing the heart rhythm in a client experiencing palpitations and faintness. Peripheral pulse volume may not change significantly with certain arrhythmias or cardiac issues that affect the central circulation more directly.
