A nurse is caring for a client who is experiencing acute kidney failure after a surgical procedure. Telemetry monitoring shows a widened QRS, frequent premature ventricular contractions, and a heart rate of 55/min. Which of the following electrolyte imbalances should the nurse identify?
Hyperkalemia.
Hypocalcemia.
Hyperglycemia.
Hypophosphatemia.
The Correct Answer is A
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.

Correct Answer is D
Explanation
Answer: D. A client whose medications to manage Parkinson's disease are no longer effective.
Rationale:
A) A client who is newly diagnosed with type 1 diabetes mellitus and cannot afford insulin:
While this client has a significant medical issue, the primary concern here is financial rather than palliative. Palliative care focuses on providing relief from symptoms and improving quality of life for those with serious illnesses. Addressing the client's financial issues might involve social services or community resources rather than palliative care.
B) A client who has Meniere's disease and cannot safely ambulate due to vertigo:
Meniere's disease, while debilitating, may not necessarily require palliative care unless the symptoms are severely impacting the client's quality of life in a way that is not manageable with current treatments. Palliative care could be considered if the disease is severely limiting function and other supportive care is needed.
C) A client who had a stroke and cannot eat or drink without choking:
This client is experiencing a significant functional impairment due to the stroke, which might benefit from rehabilitative services rather than palliative care. Palliative care would be more appropriate if the client's condition is progressive, severe, and not responsive to treatment, leading to a focus on comfort and quality of life.
D) A client whose medications to manage Parkinson's disease are no longer effective:
When medications for Parkinson's disease are no longer effective, the client may be experiencing advanced symptoms and a decline in quality of life. Palliative care can provide symptom management, support, and enhance the client's quality of life when conventional treatments are no longer effective in controlling symptoms.
Correct Answer is C
Explanation
Answer: C. "Insert the entire needle into your skin to administer medication completely."
Rationale:
A) "Administer this medication into your leg muscle."
Enoxaparin should be administered subcutaneously, typically in the abdominal area, not into a muscle. Injecting it intramuscularly can lead to unpredictable absorption and increase the risk of bleeding.
B) "Expel the excess air in the syringe before you administer the medication."
This statement is incorrect. For enoxaparin, it is recommended to retain the air bubble in the syringe. The air bubble helps ensure the entire dose is delivered and minimizes leakage at the injection site.
C) "Insert the entire needle into your skin to administer medication completely."
This is an appropriate instruction as it emphasizes the need to fully insert the needle for effective subcutaneous delivery of enoxaparin. Proper technique is essential to ensure the medication is administered as intended.
D) "Take ibuprofen for fever following administration of this medication."
This recommendation is not advisable because ibuprofen, a non-steroidal anti-inflammatory drug (NSAID), can increase the risk of bleeding, especially when taken concurrently with enoxaparin. The client should consult their healthcare provider for safe alternatives for managing fever or pain.
