Question 1 of 5.
Which of the following findings would necessitate discontinuing an IV potassium infusion in an adult with ketoacidosis?
A. Urine output 22 mL/hr for 2 hours
B. Serum potassium level of 3.7
C. Small T wave of ECG
D. Serum glucose level of 180
Explanation: Adequate renal flow of 30 mL/hr is a necessity with potassium infusions because potassium is excreted renally. Because potassium level will decrease during correction of diabetic ketoacidosis, potassium will be infused even if plasma levels of potassium are normal. A small T wave is normal and desired on the electrocardiogram. A tall, peaked T-wave could indicate overinfusion of potassium and hyperkalemia. Glucose levels of <200 are desirable.

A client is admitted with disseminated herpes zoster (shingles). According to the Centers for Disease Control Guidelines for Infection Control:
A. Airborne precautions will be needed.
B. No special precautions will be needed.
C. Only contact precautions will be needed.
D. Droplet precautions will be needed.
Explanation: Disseminated herpes zoster requires airborne precautions because the varicella-zoster virus can spread through respiratory droplets in immunocompromised patients.

A. Add more water to the suction-control chamber.
B. Remove the drainage using a 60 mL syringe.

D. Prepare a new unit for continuing collection.
Explanation: A full collection chamber requires replacing the chest drainage unit to maintain effective drainage and prevent complications like tension pneumothorax.
