The charge nurse observes a practical nurse (PN) measuring the waist circumference of a client who has expressed a concern about health problems related to obesity. Which action should the nurse implement?

A. Advise the PN that waist circumference measurements are valuable to assess fluid retention but not obesity. Waist circumference is actually a valuable measure for assessing abdominal obesity, which is an important factor in health, independent of BMI. It helps screen for health risks related to overweight and obesity, such as heart disease and type 2 diabetes. Therefore, this option is incorrect.B. Instruct the PN to measure the client’s waist circumference every 8 hours to assess for changes. Measuring waist circumference does not require frequent assessments like every 8 hours. It’s a simple and inexpensive measurement that provides valuable information about abdominal fat distribution. However, such frequent measurements are unnecessary and impractical for assessing obesity-related risks.C. Tell the PN that this assessment technique should be performed by the nurse. Waist circumference measurements can be performed by practical nurses (PNs) and other healthcare providers. It’s a straightforward technique that doesn’t require specialized training. Therefore, this option is incorrect.D. Review the measurement obtained by the PN and compare with ideal measurements for this client. This is the most appropriate action. The nurse should review the PNs measurement of the client’s waist circumference and compare it to established guidelines. Generally, a waist circumference greater than 35 inches for women or greater than 40 inches for men indicates increased risk of obesity-related health problems.
