The nurse is assessing internal variables that influence a client's health care beliefs and practices. As part of this assessment, the nurse should consider the client's:

D. When uncertain about the endpoint of Korotkoff sounds, releasing the cuff completely allows the blood flow to return to normal in the arm. After waiting for about two minutes, the nurse can reinflate the cuff and begin the measurement process again. This approach helps ensure accurate measurement by resetting conditions and allowing for a clearer determination of when Korotkoff sounds start and stop.

A. This option is not recommended because re-inflating the cuff immediately could lead to incorrect readings due to inaccurate pressure settings or discomfort for the client. It does not address the issue of determining the endpoint of the Korotkoff sounds.

B. This technique involves palpating the radial pulse while inflating the cuff and then inflating the cuff until the pulse is no longer palpable. This method can help ensure the cuff is inflated to an appropriate pressure level, which is typically about 30 mmHg above the point where the radial pulse disappears.

However, this option does not directly address the uncertainty about when to listen for the Korotkoff sounds to stop.

C. This option is not practical for addressing the immediate uncertainty during the current blood pressure measurement. Waiting 30 minutes to retake the blood pressure with a different cuff may delay necessary assessment and intervention.

Total Volume (ml) / Rate (ml/hr) = Time (hr).

For a client receiving 2 liters of IV fluid at a rate of 125 ml/hr,

Convert liters to milliliters (since 1 liter = 1000 ml, therefore 2 liters = 2000 ml). Then, divide the total volume by the rate: 2000 ml / 125 ml/hr = 16 hours.

So, the nurse should expect the IV fluids to last for 16 hours.
