A nurse is caring for a client who has a prescription for warfarin. Which of the following laboratory tests should the nurse monitor?

Understanding the literacy level of the older adults is crucial for developing an effective education program. It helps the nurse tailor the content, language, and teaching methods to ensure that the material is accessible and understandable to the participants. By assessing their literacy level, the nurse can identify any potential barriers to learning and make appropriate adjustments to promote effective communication and comprehension.

Once the literacy level is determined, the nurse can then proceed with the other actions, such as establishing learning outcomes, scheduling a time to implement the program, and creating handouts that are suitable for the participants' literacy level. However, determining the literacy level should be the first step in order to create an inclusive and effective educational experience for the older adults.

The normal range for potassium levels is generally between 3.5 to 5.0 mEq/L. A potassium level of 3.5 mEq/L falls within the lower end of the normal range, suggesting that the client's potassium levels are relatively stable. This finding alone does not indicate the overall effectiveness of the behavioral plan.

The normal range for sodium levels is typically between 135 to 145 mEq/L. A sodium level of 130 mEq/L falls below the normal range and indicates hyponatremia (low sodium levels). Hyponatremia can be a cause for concern, and it suggests that the behavioral management plan may need further attention or adjustments.

The normal range for hemoglobin (Hgb) levels varies depending on factors such as age and gender. However, in general, a Hgb level of 10 g/dL falls below the normal range and indicates anemia. Anemia is a common complication in individuals with anorexia nervosa and can result from inadequate nutrient intake. This finding suggests that the behavioral plan may need further evaluation and adjustment to address the client's nutritional needs.

Body Mass Index (BMI) is a measure that relates weight and height. A BMI of 14.5 indicates severe underweight and is well below the normal range. This finding suggests that the client's nutritional status is still significantly compromised, and the behavioral management plan may require further attention to support weight restoration and overall recovery.
