The nurse is reviewing laboratory results for a group of patients. Which value should be of most concern to the nurse?

Sodium level 140 mEq/L (136-145 mEq/L)

Magnesium level 1.0 mEq/L (1.3-2.1 mEq/L)

Calcium level 10 mg/dL (9-10.5 mg/dL)

Potassium level 3.5 mEq/L (3.5-5 mEq/L)

Answer and Explanation

The Correct Answer is B

A. Sodium level 140 mEq/L (136-145 mEq/L): This sodium level is within the normal range and is not of concern.

B. Magnesium level 1.0 mEq/L (1.3-2.1 mEq/L): This value is below the normal range, indicating hypomagnesemia, which can cause serious complications such as arrhythmias, neuromuscular irritability, and seizures. This is the most concerning value.

C. Calcium level 10 mg/dL (9-10.5 mg/dL): This calcium level is within the normal range and is not concerning.

D. Potassium level 3.5 mEq/L (3.5-5 mEq/L): This potassium level is at the low end of normal. While it is something to monitor, it is not immediately concerning compared to hypomagnesemia.

Correct Answer is A

Explanation

A. A patient who lost 2 liters of blood during surgery: This is the most acute and severe form of hypovolemia due to significant blood loss, requiring immediate fluid replacement and hemodynamic monitoring.

B. A patient who received 6 liters of IV fluid: This patient is at risk for hypervolemia, not hypovolemia, due to fluid overload.

C. A patient with UTI on PO meds: While dehydration may occur, it is typically mild and does not cause hypovolemia.

D. A patient with congestive heart failure: CHF usually leads to fluid retention, making hypovolemia unlikely unless there are other complicating factors.

Correct Answer is ["50"]

Explanation

Flowrate(gtt/min) = Volume /Time× Dropfactor(gtt/mL)

Rate= 400ml /8hr ×60min/hr×60 gtt/mL

=400ml /480 × 60 gtt/mL

=50 gtt/min
