For a patient who is experiencing an ECV excess, the nurse plans to determine the fluid status. The best way for the nurse to determine the fluid balance for the patient is to:

obtain diagnostic test results

weigh the patient daily

monitor IV fluid intake

assess vital signs

Answer and Explanation

The Correct Answer is B

B. Daily weight measurements are a practical and effective method to assess fluid balance. Changes in weight can reflect fluid retention or loss. Daily weighing is particularly useful for monitoring fluid status in patients with known or suspected fluid excess. It helps detect trends over time and guides adjustments in fluid management.

A. While diagnostic tests are crucial for assessing underlying causes and complications of fluid imbalance, they do not directly provide a real-time assessment of fluid balance or volume overload.

C. Monitoring IV fluid intake provides information on the amount of fluid input but does not directly indicate how the patient's body is handling or retaining that fluid. It complements other methods like daily weight measurements.

D. Vital signs are essential for assessing the hemodynamic status and response to fluid therapy but are not specific enough to quantify fluid balance or detect mild fluid excess without other signs.

Correct Answer is C

Explanation

A. Leaving small air bubbles in the new infusion tubing is incorrect. Air bubbles should be primed out of the tubing before use to prevent air embolism.

B. Inserting the new device distal to the old IV site is incorrect. The new IV site should be placed proximal to the old site to avoid complications from previous catheter use and ensure proper circulation.

C. Wearing clean gloves during the new IV insertion is correct. Clean gloves are appropriate when inserting a new short peripheral IV device. Sterile gloves are generally required for more invasive procedures, but when changing the device itself, clean gloves are sufficient.

D. Shaving the hair on the client's skin before inserting the new IV is incorrect. Shaving the skin is not recommended because it can cause small nicks that increase the risk of infection. Clipping the hair, if necessary, is the preferred method.

A. 0.5-1.5mEq/L B. 1.3-2.1 mEq/L C. 2.5-3.5 mEq/L D. 1.0-3.0 mEq/L

Correct Answer is B

Explanation

B. This range represents the normal serum magnesium level. It is important for maintaining neuromuscular function and other vital processes in the body.

A. This range is too low for normal serum magnesium levels. Magnesium levels below this range can indicate hypomagnesemia, which can lead to symptoms such as muscle cramps, tremors, and cardiac arrhythmias.

C. This range is too high for normal serum magnesium levels. Elevated magnesium levels (hypermagnesemia) can occur in conditions such as renal failure or excessive magnesium intake, leading to symptoms like weakness, decreased reflexes, and in severe cases, cardiac arrest.

D. While this range is broader and includes the correct normal range (1.3-2.1 mEq/L), it also includes values that are below and above normal. Values below 1.3 mEq/L can indicate hypomagnesemia, while values above 2.1 mEq/L can indicate hypermagnesemia.
