Which nursing action is most helpful in promoting circulation in a client with chronic venous insufficiency?

Limit intake of chips and pretzels.

Encourage mountain biking.

Elevate lower extremities.

Restrict fluid intake to water.

Answer and Explanation

The Correct Answer is C

A.   Chips and pretzels are high in sodium, which can contribute to fluid retention and exacerbate symptoms of CVI. While reducing sodium intake can help manage fluid retention and swelling, it is not the most direct action for promoting circulation itself. It’s more of an adjunctive measure that can support overall management of CVI but does not directly improve venous circulation.
B.   Mountain biking is an intense physical activity that may not be suitable for all clients with chronic venous insufficiency, especially if they have significant symptoms or mobility issues. High-impact exercises can potentially exacerbate symptoms or lead to injury. Low-impact activities are generally recommended to improve circulation and manage CVI.
C.   Elevating the lower extremities is a highly effective measure for promoting circulation in clients with chronic venous insufficiency. It helps reduce venous pressure and promotes the return of blood to the heart, thereby alleviating swelling and discomfort. This action is directly beneficial in managing CVI.
D.   Restricting fluid intake to water alone does not directly address the underlying issues of venous insufficiency. While managing overall fluid intake can be part of a comprehensive plan to prevent excessive fluid retention, it is not the most direct or effective action for promoting circulation compared to elevating the legs.

Correct Answer is ["31"]

Explanation

Total volume in mL x Drop factor) / Total time in minutes.

For the vancomycin infusion, the total volume is 250 mL, the drop factor is 15 gtt/mL, and the total time is 120 minutes (2 hours).

The calculation is as follows: (250 mL x 15 gtt/mL) / 120 minutes = 31.25 gtt/min.

After rounding to the nearest whole number, the nurse should regulate the infusion to 31 gtt/min.

A. Calcium level 7.2 mg/dL (1.8 mmol/L). B. Potassium level 3.8 mg/dl. (3.8 mmol) C. Sodium level 140 mEq/L (140mmol/L). D. Oxygen saturation level 97%.

Correct Answer is A

Explanation

A. This calcium level is below the normal reference range (8.4 to 10.6 mg/dL or 2.10 to 2.50 mmol/L), indicating hypocalcemia. Calcium plays a crucial role in cardiac muscle contraction and electrical conduction. Low calcium levels can lead to various cardiac dysrhythmias, including prolonged QT intervals and increased risk of ventricular arrhythmias.

B. This potassium level falls within the normal range (3.5 to 5.0 mEq/L or 3.5 to 5.0 mmol/L). Potassium is essential for maintaining normal cardiac rhythm, but a level of 3.8 mg/dL is not abnormal and, therefore, is less likely to be the cause of a dysrhythmia compared to abnormal levels.
C. This sodium level is within the normal reference range (136 to 145 mEq/L or 136 to 145 mmol/L). Sodium levels typically do not directly cause dysrhythmias unless they are extremely high or low, which is not the case here. Thus, a sodium level of 140 mEq/L is not likely to be the primary contributor to the dysrhythmia.
D. This oxygen saturation level is considered normal (95% to 100%). While oxygenation is critical for overall heart function and can influence cardiac health, a saturation level of 97% is not likely to be a direct cause of a dysrhythmia, especially if it falls within the normal range.
