A nurse is caring for a client who is to receive potassium replacement. The provider’s prescription reads, “Potassium chloride 30 mEq in 0.9% sodium chloride 100 mL IV over 30 min.” For which of the following reasons should the nurse clarify this prescription with the provider?
The potassium infusion rate is too rapid.
Another formulation of potassium should be given IV.
Potassium chloride should be diluted in dextrose 5% in water.
The client should be treated by giving potassium by IV bolus.
The Correct Answer is A
According to various guidelines12345, the recommended rate of intravenous potassium replacement is 10-20 mEq/h with continuous ECG monitoring. The maximum rate is 40 mEq/h in emergency situations. The prescription given by the provider exceeds this limit and could cause cardiac arrhythmias or hyperkalemia.
Choice B is wrong because potassium chloride is a common and appropriate formulation of potassium for intravenous administration.
Choice C is wrong because potassium chloride should not be diluted in dextrose 5% in water, as this could cause hyperglycemia or osmotic diuresis.
Choice D is wrong because potassium should never be given by IV bolus, as this could cause cardiac arrest or tissue necrosis.

Correct Answer is D
Explanation
The most appropriate action for the nurse to take in this situation is:
d. Apply a warm, moist compress.
Here's why the other options are not recommended:
- a. Initiate a new IV distal to the initial site:This is not the first course of action. While starting a new IV might be necessary eventually, it's crucial to address the issue at the current site first.
- b. Slow the IV solution rate:Slowing the rate doesn't directly address the coolness and edema, which indicate potential infiltration or extravasation.
- c. Maintain the extremity below the level of the heart:This action would actually worsen the edema by promoting fluid accumulation at the site.
Applying a warm, moist compress can help promote absorption of any leaked fluid and improve circulation at the site. However, it's important to remember that this is just one step in the process. The nurse should also:
- Stop the IV infusion.
- Assess the extent of the infiltration or extravasation.
- Document the findings.
- Elevate the affected extremity.
- Consult with a physician for further instructions and potential treatment.
Correct Answer is A
Explanation
This is because it uses the full name of the drug, the exact dose, the route of administration, the frequency, and the indication for use. It also avoids any abbreviations that could be confused with other drugs or measurements.
Choice B is wrong because MS is an abbreviation for morphine sulfate which could be mistaken for magnesium sulfate.
Choice C is wrong because MSO4 is an abbreviation for morphine sulfate that could be mistaken for magnesium sulfate.
Choice D is wrong because 6.0 mg could be misread as 60 mg and lead to a tenfold overdose.
Normal ranges for morphine dosage depend on the route of administration, the indication, and the patient’s tolerance and response.
For acute pain, the usual oral dose is 10 to 30 mg every 4 hours as needed. For chronic pain, the usual oral dose is 15 to 30 mg every 8 to 12 hours as needed.
For intravenous (IV) administration, the usual dose is 2.5 to 15 mg every 4 hours as needed.
The morphine equivalent daily dose (MEDD) is a concept that attempts to establish an equivalency in terms of dose when comparing any opioid to morphine.
