Ordered: Replace K\(^+\) per protocol.

The patient's K\(^+\) level is 3.4. The patient is NPO and needs 30 mEq of K\(^+\). How will you administer 30 mEq of K\(^+\) IV? Are there any precautions?

The medication is available in K\(^+\) 10 mEq per 100 mL. Determine the pump rate and explain how you will administer it.

Answer :

Final answer:

To administer 30mEq of K+ IV, you'd need 300 mL of the prescribed solution. In adults, generally it should not exceed an infusion rate of 10 mEq/hour. Monitor heart rhythm and ensure proper IV function due to risks of arrhythmia and extravasation.

Explanation:

The IV administration of potassium (K+) must be executed with caution. Given the prescribed order of 30mEq of K+ and the medication available is in a concentration of 10mEq per 100 mL, you would need 300 mL to fulfill the prescribed dosage.

The infusion rate would then depend on your institution's protocol and patient's condition, but typically, the rate for potassium IV should not exceed 10 mEq/hour in adults without a heart monitor. Therefore, you might administer the K+ over approximately 3 hours.

There are serious precautions to respect with IV potassium administration. It's important to ensure the IV is functioning properly to avoid extravasation and tissue damage, and continuous heart monitoring is necessary due to the risks of arrhythmia.

Furthermore, be aware that the K+ level mentioned (3.4) is on the lower end of the normal range, and the patient is NPO (nil per os/not eating), adding to the critical nature of this administration.
