A nurse is caring for a client who is receiving an IV infusion of potassium chloride. Which of the following complications should the nurse recognize as an indication to discontinue the infusion?

Hypomagnesemia

Neutropenia

Coughing

Hyperkalemia

Answer and Explanation

The Correct Answer is D

A. Hypomagnesemia: Low magnesium levels are not an indication to stop a potassium infusion, although magnesium and potassium levels are related. Correction of magnesium may be necessary, but hypomagnesemia alone does not warrant discontinuation.

B. Neutropenia: A low white blood cell count is not directly related to potassium administration and does not require stopping the infusion.

C. Coughing: Respiratory symptoms like coughing are not a recognized complication of potassium chloride infusion and do not indicate the need to discontinue therapy.

D. Hyperkalemia: Elevated potassium levels can be life-threatening due to the risk of cardiac arrhythmias. If laboratory results or clinical signs indicate hyperkalemia, the potassium infusion should be immediately discontinued and appropriate interventions initiated.

Correct Answer is A

Explanation

A. "The pump will not deliver any medication during the lockout period.": The lockout interval is a safety feature that prevents overdose by ensuring the pump cannot deliver additional doses until a set time has passed. Understanding this helps the client use the PCA safely.

B. "I should wait to push the pain button until the pain becomes severe.": PCA is most effective when the client administers medication at the onset of pain rather than waiting for it to become severe, as early administration prevents pain from escalating.

C. "My partner can push the pain button for me if I fall asleep.": Only the client should operate the PCA pump to prevent accidental overdose. Allowing someone else to push the button violates safety protocols.

D. "I will be asked to describe and rate my pain every 8 hours.": Pain assessment should be frequent, especially in the first 24 hours of PCA use, to adjust therapy and monitor effectiveness. An 8-hour interval may not provide timely information to manage pain effectively.

Correct Answer is ["1.5"]

Explanation

Calculation:

Calculate the total dose in milligrams (mg).

Ordered dose: 0.02 mg/kg

Patient weight: 30 kg

Total dose (mg) = 0.02 mg/kg x 30 kg

= 0.6 mg.

Calculate the volume to administer in milliliters (mL).

Total dose: 0.6 mg

Available concentration: 0.4 mg/mL

Volume (mL) = Total Dose (mg) / Available Concentration (mg/mL)

= 0.6 mg / 0.4 mg/mL

= 1.5 mL.
