The nurse is caring for a patient with Parkinson's Disease.
While writing the care plan for the patient, what would be an appropriate diagnosis?

Choice A rationale

The small intestine is where nutrients are absorbed, but it is not where vitamin D is activated. Vitamin D is first converted in the liver and then activated in the kidneys to promote calcium absorption.

Choice B rationale

This is incorrect because vitamin D is activated into a form that promotes calcium absorption. The active form is crucial for maintaining calcium and phosphate levels in the blood.

Choice C rationale

The kidneys play a significant role in converting vitamin D to its active form, calcitriol. This activated form is essential for the absorption of calcium in the intestines.

Choice D rationale

The large intestine is involved in water absorption and waste formation but not in the activation of vitamin D. The activation process primarily occurs in the kidneys and liver. .

Choice A rationale

True. Xanthine derivatives like theophylline can cause serious adverse effects, including brain damage, when blood levels become too high. It is critical to monitor theophylline levels to prevent toxicity and associated neurological complications.

Choice B rationale

False. If xanthine levels remain within therapeutic ranges, the risk of brain damage is minimized. However, this statement is incorrect as it does not acknowledge the potential severity of the adverse effects linked to elevated theophylline levels.
