Correct Answer is C
Explanation
Choice A reason: Coercing treatment violates the voluntary client’s autonomy. Legally, voluntary patients can refuse medication unless they pose imminent danger, requiring involuntary commitment. Manipulation or disruption does not meet legal criteria for forced treatment, as mental health laws prioritize patient rights absent clear harm risks.
Choice B reason: A 302 (involuntary commitment) requires evidence of imminent danger to self or others, not just disruptive behavior. Family petitions cannot override this legal threshold without clinical justification, and manipulation alone does not qualify, making this option incorrect for enforcing treatment in a voluntary client.
Choice C reason: As a voluntary client, the individual retains the right to refuse treatment unless deemed a danger to self or others. Mental health laws protect autonomy, and manipulation or lack of progress does not justify forced medication, making refusal a legal right in this scenario.
Choice D reason: Involuntary commitment by a doctor requires evidence of imminent danger or inability to care for oneself, not just disruptive behavior or nonadherence. Without such criteria, the client’s voluntary status protects their right to refuse, making involuntary commitment legally inappropriate in this situation.
Correct Answer is ["A","B","C"]
Explanation
Choice A reason: Hypertension and obesity (BMI 30) are major risk factors for ESRD. Chronic hypertension damages renal vasculature, reducing glomerular filtration over time. Obesity exacerbates hypertension and promotes glomerulosclerosis, leading to progressive kidney damage. This combination significantly increases the risk of developing ESRD through sustained renal injury.
Choice B reason: Vascular disorders, such as atherosclerosis, impair renal blood flow, causing ischemic nephropathy. Chronic reduced perfusion damages nephrons, leading to progressive renal failure. Vascular diseases also contribute to hypertension, further stressing kidneys. This client’s history indicates a high risk for ESRD due to ongoing vascular compromise affecting renal function.
Choice C reason: Poorly controlled diabetes mellitus causes diabetic nephropathy, a leading cause of ESRD. Chronic hyperglycemia damages glomerular capillaries, leading to proteinuria and declining kidney function. Sustained high glucose levels accelerate nephron loss, making this client at high risk for ESRD due to irreversible renal damage from diabetes.
Choice D reason: Chronic obstructive pulmonary disease (COPD) primarily affects the lungs, not the kidneys. While hypoxia or medications like corticosteroids may indirectly stress kidneys, COPD is not a direct risk factor for ESRD. Renal damage requires specific insults like hypertension or diabetes, making this client less likely to develop ESRD.
Choice E reason: A recent dehydration episode from gastroenteritis can cause acute kidney injury but is reversible with treatment. It is not a chronic condition leading to ESRD unless recurrent or combined with other risk factors like diabetes or hypertension. This isolated event poses a lower risk for ESRD development.
