A nurse is caring for a client who has been prescribed parenteral lidocaine. Before administering the medication, the nurse should review the medical record for which condition?
Glaucoma.
Heart block.
Gastric ulcers.
Diabetes mellitus.
The Correct Answer is B
Choice A reason: Glaucoma is not directly related to the administration of lidocaine, as it does not affect intraocular pressure or the pathophysiology of glaucoma.
Choice B reason: Heart block is a type of arrhythmia where the electrical signal is delayed or blocked entirely. Since lidocaine affects cardiac conduction, it is crucial to review the medical record for heart block before administration.
Choice C reason: Gastric ulcers are not typically a concern when administering lidocaine, as it does not have gastrointestinal effects when given parenterally.
Choice D reason: Diabetes mellitus is not a contraindication for lidocaine administration; however, monitoring blood glucose levels is always important in diabetic patients receiving any medication.

Explanation
Choice A reason: While obtaining a 12-lead electrocardiogram is important for monitoring cardiac function, it is not as frequent or specific as potassium monitoring for hyperkalemia management.
Choice B reason: Evaluating glucose levels is necessary due to the risk of hypoglycemia from insulin administration, but the priority is monitoring potassium levels in hyperkalemia.
Choice C reason: Monitoring intake and output is part of fluid balance management but is secondary to the critical need to monitor serum potassium levels.
Choice D reason: Frequent assessment of serum potassium levels is essential to evaluate the effectiveness of the dextrose and insulin therapy in lowering potassium levels.
