A client is being treated for tumor lysis syndrome. Which nursing intervention should the nurse prioritize to minimize complications associated with this condition?

Parkinson’s disease is a progressive neurodegenerative disorder characterized by the loss of dopamine-producing neurons in the substantia nigra of the brain. This dopamine deficiency leads to motor symptoms such as tremors, rigidity, bradykinesia, and postural instability. Carbidopa-levodopa is the standard pharmacologic treatment used to restore dopamine activity in the central nervous system. It works by increasing dopamine availability in the brain, improving motor function and reducing symptoms.

Rationale:
A. It blocks acetylcholine release in the brain is incorrect because carbidopa-levodopa does not directly inhibit acetylcholine activity. While anticholinergic drugs may be used in Parkinson’s disease to reduce tremors, this medication primarily targets dopamine replacement rather than acetylcholine suppression. Its main mechanism is not based on cholinergic blockade.

B. It enhances the reuptake of dopamine in the synapses is incorrect because carbidopa-levodopa does not work by increasing dopamine reuptake. Dopamine reuptake inhibitors are a different class of medications that prolong dopamine action in the synaptic cleft. Carbidopa-levodopa instead increases the actual synthesis of dopamine in the brain.

C. It increases the production of dopamine in the brain is correct because levodopa is a precursor that crosses the blood-brain barrier and is converted into dopamine in the central nervous system. Carbidopa prevents peripheral breakdown of levodopa, allowing more of it to reach the brain. This results in increased dopamine levels, improving motor control and reducing Parkinsonian symptoms.

D. It inhibits the breakdown of serotonin in the brain is incorrect because carbidopa-levodopa does not affect serotonin metabolism. Serotonin reuptake inhibition or breakdown prevention is associated with antidepressant medications, not antiparkinsonian therapy. The drug’s primary action is specifically related to dopamine synthesis rather than serotonin regulation.

Severe burns covering a large total body surface area trigger a profound hypermetabolic and catabolic response due to increased inflammatory mediators and stress hormones. This leads to rapid protein breakdown, muscle wasting, impaired wound healing, and increased infection risk. Clients on mechanical ventilation with major burns require early nutritional support to preserve lean body mass and support tissue repair. Enteral feeding is preferred whenever the gastrointestinal tract is functional.

Rationale:
A. Starting total parenteral nutrition (TPN) immediately without assessing gastrointestinal function is not the initial intervention because the gut should be used whenever possible. Parenteral nutrition is associated with higher risks of infection, metabolic complications, and loss of gut mucosal integrity. Enteral feeding is safer, more physiologic, and helps maintain intestinal barrier function.

B. Initiating early enteral nutrition (EN) as soon as possible is the most appropriate intervention because it supports metabolic demands and promotes gut integrity. Early feeding reduces bacterial translocation, decreases infection risk, and improves wound healing in burn clients. It also helps counteract the hypermetabolic state by providing essential calories and protein for tissue repair.

C. Providing oral diet consisting of high-calorie supplements is not appropriate for a mechanically ventilated client. These clients are often unable to safely swallow or meet nutritional needs orally due to intubation and critical illness. Oral intake is typically not feasible in the acute phase of severe burns and ventilation support.

D. Delaying nutritional interventions until the client is stable and can tolerate feeding is inappropriate because early nutrition is critical in burn management. Delayed feeding worsens catabolism, increases infection risk, and impairs healing. Guidelines emphasize initiating nutrition within the first 24–48 hours if possible, rather than waiting for full clinical stability.
