A nurse in an emergency department is assessing a client who is overusing prescribed diuretics and has a sodium level of 127 mEq/L. Which of the following laboratory findings should the nurse expect?

Choice A rationale:
The combination of widened QRS, frequent premature ventricular contractions (PVCs), and bradycardia (heart rate of 55/min) on telemetry monitoring suggests hyperkalemia. Elevated potassium levels in the blood can cause delayed repolarization of cardiac cells, leading to widened QRS complexes and PVCs. Bradycardia is another common manifestation of hyperkalemia.
Choice B rationale:
Hypocalcemia, characterized by low calcium levels in the blood, can lead to cardiac arrhythmias, but it typically presents with a prolonged QT interval rather than widened QRS complexes and PVCs.
Choice C rationale:
Hyperglycemia, which is high blood glucose levels, does not directly affect the electrocardiogram (ECG) parameters like QRS width or heart rate. It may have systemic effects, but it is not responsible for the ECG changes described in the scenario.
Choice D rationale:
Hypophosphatemia, or low levels of phosphate in the blood, can cause muscle weakness and may have systemic effects, but it is not associated with the specific ECG changes seen in hyperkalemia, such as widened QRS complexes and PVCs.

Choice A rationale:
Applying clean gloves when removing the old dressing from the catheter site is essential to prevent infection and maintain an aseptic technique during peritoneal dialysis catheter care. Gloves protect both the nurse and the patient from potential contamination.
Choice B rationale:
Cleansing the area by using a circular motion beginning at the catheter site and moving outward is not the correct technique. When caring for a dialysis catheter, the nurse should cleanse the site using an outward, circular motion starting from the insertion site to minimize the risk of contamination.
Choice C rationale:
Using warm water to cleanse the catheter site is not recommended. The peritoneal dialysis catheter site should be cleaned with an appropriate antiseptic solution or disinfectant, as warm water alone may not effectively remove bacteria or prevent infections.
Choice D rationale:
Placing an occlusive dressing over the catheter site after cleaning is not the standard practice for peritoneal dialysis catheter care. Typically, a clean, dry dressing is applied to the catheter site after cleaning to keep it clean and dry, but it should not be occlusive.
