A nurse is teaching an older adult client who has osteoporosis about ways to promote musculoskeletal health. Which of the following instructions should the nurse include?

Choice A rationale:
Notifying the surgeon of the temperature elevation is important, but it is not the nurse's priority. A temperature elevation after abdominal surgery could be a sign of infection, but the immediate action should be to assess the surgical incision for any signs of infection.
Choice B rationale:
Encouraging the client to drink more fluids is a good practice to maintain hydration and promote recovery after surgery. However, it is not the nurse's priority in this situation. The elevated temperature and potential infection take precedence over increasing fluid intake.
Choice C rationale:
This is the correct answer because the nurse's priority is to assess the surgical incision for signs of infection. An elevated temperature is a significant finding after surgery, and it may indicate a surgical site infection, which requires prompt assessment and intervention.
Choice D rationale:
Monitoring vital signs every 4 hours is an essential nursing intervention after surgery, but it is not the priority when the client has an elevated temperature and a recent surgical incision.
The nurse must first assess for signs of infection before proceeding with routine vital sign monitoring.

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.
