A nurse is caring for a client who is ordered Potassium 40 mEq IV. On hand is Potassium Chloride 20 mEq/mL. What is the nurse’s next action?

Mix potassium in 1 liter of normal saline.

Call the physician for order clarification.

Prepare 20 mEq of Potassium to give IV push.

Give the medication as ordered.

Answer and Explanation

The Correct Answer is B

A. While potassium is typically diluted in IV fluids, the concentration and infusion rate must be clarified before administration. A standard dilution is 10 mEq in 100 mL or 40 mEq in 1L, but this must be verified.
B. Calling the physician for clarification is the safest step. IV potassium should never be given undiluted or as an IV push due to the risk of fatal cardiac arrhythmias.
C. IV push potassium is never appropriate as it can cause cardiac arrest.
D. Administering the undiluted 20 mEq/mL solution is dangerous and requires proper dilution before administration.

Correct Answer is D

Explanation

A. Hyperkalemia is not a typical complication of thiazide diuretics. Instead, they promote potassium loss, increasing the risk of hypokalemia.
B. Hypoglycemia is not directly associated with thiazide diuretics. These medications may affect glucose tolerance but do not cause low blood sugar.
C. Seizures are not a common adverse effect of thiazide diuretics. While severe electrolyte imbalances could contribute to neurological symptoms, they are not the primary concern in this scenario.
D. Cardiac dysrhythmias can result from hypokalemia, a common side effect of thiazide diuretics. Potassium is essential for normal cardiac conduction, and low levels can lead to palpitations, weakness, and potentially life-threatening arrhythmias.

A. Consuming a high-calcium diet B. A client on bedrest C. A post-operative client D. Oral contraceptive use E. Client with a low BMI

Correct Answer is ["B","C","D"]

Explanation

A. A high-calcium diet does not contribute to DVT development. DVT risk factors are related to venous stasis, hypercoagulability, and endothelial damage.
B. Prolonged bed rest leads to venous stasis, increasing the risk of clot formation.
C. Post-operative clients are at higher risk for DVT due to immobility and surgical trauma, which can activate clotting mechanisms.
D. Oral contraceptive use increases the risk of DVT due to hormonal effects that promote clot formation.
E. A low BMI is not a risk factor for DVT. In contrast, obesity is a recognized risk factor due to increased venous pressure and inflammation.
