A nurse is caring for a client with chronic kidney disease (CKD) who presents with hyperkalemia. Which of the following interventions should the nurse implement first?

Choice A rationale
The left extrapyramidal tract is involved in motor control, but lesions here would not cause right homonymous hemianopia or inability to move the right arm. These symptoms are more indicative of a lesion in the cerebral hemisphere.
Choice B rationale
A lesion in the right cerebral hemisphere would cause left-sided symptoms, not right-sided. The patient’s symptoms are indicative of a lesion in the left cerebral hemisphere.
Choice C rationale
The cerebellum is involved in coordination and balance, not in causing right homonymous hemianopia or inability to move the right arm. These symptoms are more indicative of a lesion in the cerebral hemisphere.
Choice D rationale
A lesion in the left cerebral hemisphere can cause right homonymous hemianopia and inability to move the right arm. This is because the left hemisphere controls the right side of the body and processes visual information from the right visual field.

Choice A rationale
Acute respiratory distress syndrome (ARDS) is characterized by severe hypoxemia and respiratory distress, often requiring mechanical ventilation. It is not typically associated with a mild fever and increased respiratory rate.
Choice B rationale
Chronic obstructive pulmonary disease (COPD) is a chronic condition characterized by airflow limitation and respiratory symptoms, but not typically associated with a mild fever.
Choice C rationale
Pulmonary edema involves fluid accumulation in the lungs, leading to respiratory distress and hypoxemia, but not typically associated with a mild fever.
Choice D rationale
Pneumonia is an infection of the lungs causing fever (37.5°C), increased respiratory rate (28 breaths per minute), and other respiratory symptoms. It is the most likely condition given the symptoms.
