A nurse is providing education to a client who is reviewing a consent form for a surgical procedure. Which of the following statements by the client indicates an understanding of the consent?

Choice A reason: Hypernatremia is unlikely with 0.45% sodium chloride, a hypotonic solution that dilutes serum sodium. Over-infusion risks hyponatremia, not high sodium levels. Monitoring for hypernatremia is inappropriate, as the solution’s low sodium content does not contribute to elevated sodium in fluid therapy.
Choice B reason: Assessing for fluid overload is essential, as 0.45% sodium chloride, being hypotonic, can cause water to shift into cells, risking pulmonary or cerebral edema. This is critical in clients with renal or cardiac issues, where monitoring for dyspnea or swelling ensures safe fluid administration.
Choice C reason: Hypoglycemia is not directly linked to 0.45% sodium chloride, which affects fluid and electrolytes, not glucose. Fluid shifts may indirectly stress metabolism, but hypoglycemia relates to fasting or insulin issues, making this an inappropriate focus for monitoring in this fluid therapy context.
Choice D reason: Dehydration is unlikely, as 0.45% sodium chloride provides free water, promoting hydration. It corrects hypernatremia or replaces fluid losses. Evaluating for dehydration is unnecessary unless infusion is inadequate or losses persist, which is not indicated in the context of this hypotonic solution.

Choice A reason: Amitriptyline, a tricyclic antidepressant, typically causes hypotension via alpha-adrenergic blockade, not hypertension. Expecting blood pressure elevation shows misunderstanding, as its cardiovascular effects require monitoring for orthostatic changes, not hypertensive risks, in depression treatment.
Choice B reason: Acknowledging a 2-4 week delay for amitriptyline’s effect shows understanding, as tricyclics increase synaptic serotonin and norepinephrine gradually, requiring neuroplastic changes for mood improvement. This reflects accurate knowledge of the drug’s onset, critical for managing expectations in depression therapy.
Choice C reason: Taking amitriptyline on an empty stomach is incorrect, as food reduces gastrointestinal side effects like nausea. Its absorption is unaffected by food, but taking it with meals improves tolerability, indicating a misunderstanding of administration guidelines for effective therapy.
Choice D reason: Morning dosing of amitriptyline is incorrect, as its sedative effects, via histamine blockade, are best utilized at bedtime to aid sleep. Morning use may cause daytime drowsiness, reducing adherence, indicating a misunderstanding of its pharmacological profile in depression management.
