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 ["A","B","D"]
Explanation
Choice A rationale:
The nurse should administer oxygen to the client experiencing a sickle cell crisis. Sickle cell crisis can cause vaso-occlusion, leading to tissue hypoxia and pain. Administering oxygen helps to improve tissue oxygenation and relieve symptoms.
Choice B rationale:
Administering opioids is appropriate for managing the severe pain associated with a sickle cell crisis. Opioids are effective analgesics that can help alleviate the acute pain experienced by the client.
Choice C rationale:
Administering whole blood is not typically indicated for a sickle cell crisis. Whole blood transfusion is reserved for specific indications, such as severe anemia or acute blood loss, but it is not a standard treatment for sickle cell crisis pain.
Choice D rationale:
Elevating the head of the bed to 30° can improve oxygenation and reduce the workload on the respiratory system, which is beneficial for clients experiencing a sickle cell crisis. It helps to optimize lung expansion and alleviate hypoxia.
Choice E rationale:
Keeping the client NPO (nothing by mouth) is not necessary in a sickle cell crisis. There is no indication that the client cannot tolerate oral intake, so allowing them to eat and drink as usual is appropriate.
Correct Answer is D
Explanation
Choice A rationale:
Fruity-smelling breath is associated with diabetic ketoacidosis (DKA), which is not the expected manifestation of chronic kidney disease (CKD). DKA occurs in uncontrolled diabetes and is not the priority for this client.
Choice B rationale:
Painful urination is not a typical clinical manifestation of chronic kidney disease. It is more commonly associated with urinary tract infections or other urological issues.
Choice C rationale:
Hypotension may occur in end-stage kidney disease, but it is not specific to chronic kidney disease and is not a priority in this scenario.
Choice D rationale:
Lethargy is a common clinical manifestation of chronic kidney disease due to the accumulation of waste products in the blood, leading to uremia. It is a priority as it indicates the progression of the disease and the need for close monitoring and intervention.
