Which condition is most likely when a patient shows sudden memory problems, complains about forgetfulness and improves with treatment of depression?
Lewy body dementia
Vascular dementia
Alzheimer's disease
Pseudodementia
The Correct Answer is D
A. Lewy body dementia: This neurodegenerative condition is characterized by fluctuating cognition, visual hallucinations, and spontaneous features of parkinsonism. It involves the abnormal accumulation of alpha-synuclein proteins in the brain, which typically leads to a progressive and irreversible decline. Symptoms do not resolve with the treatment of underlying mood disorders like major depression.
B. Vascular dementia: This type of cognitive impairment results from cerebrovascular disease or a series of small strokes that cause brain tissue ischemia. It often presents with a stepwise decline in cognitive function and focal neurological deficits based on the area of infarct. The structural damage to the vasculature and neural pathways is irreversible and does not improve with antidepressant therapy.
C. Alzheimer's disease: This is a progressive neurodegenerative disorder marked by the accumulation of amyloid plaques and tau tangles. It primarily affects memory and executive function over a slow, predictable trajectory that is not acutely reversible. While depression can co-occur, treating it does not reverse the fundamental cognitive deficits caused by the underlying neuronal death.
D. Pseudodementia: This clinical term describes a syndrome where depression mimics the symptoms of dementia, particularly in older adults. Patients often complain of memory loss and exhibit "don't know" answers during cognitive testing. Because the cognitive impairment is secondary to a functional psychiatric disorder, symptoms typically improve significantly once the depression is successfully treated.

Correct Answer is A
Explanation
A. A family struggling to afford transportation to appointments: This scenario represents a social determinant of health related to economic stability and physical infrastructure. Lack of reliable transport serves as a non-clinical barrier that prevents access to necessary healthcare services and medications. These environmental and social conditions significantly influence health outcomes and contribute to health disparities within a community.
B. A nurse documenting a medication: This action is a standard clinical procedure and a professional nursing task performed within a healthcare facility. While documentation is essential for patient safety, it describes the internal operations of the medical system rather than the social conditions of the patient. It does not reflect the external socioeconomic factors that shape the patient's baseline health status.
C. A patient receiving IV fluids in the ED: This represents a clinical intervention aimed at treating an acute physiological condition like dehydration or hypovolemia. It occurs within the secondary level of care and focuses on medical management rather than social or environmental influences. While the need for the ED visit might be influenced by social factors, the IV therapy itself is a medical treatment.
D. A therapist teaching mobility exercises: This is a rehabilitative intervention provided by an interprofessional team member to improve physical function and mobility. It is part of the clinical care plan designed to address a specific physical deficit or recovery goal. Such activities are medical services provided to the individual rather than broad social or economic determinants that impact the population.
Correct Answer is A
Explanation
A. Non-maleficence: This principle dictates the obligation to do no harm to the patient. By implementing fall precautions, the nurse proactively mitigates environmental hazards to prevent physical trauma. This duty focuses on the avoidance of negligent care and the prevention of adverse events that could lead to injury.
B. Beneficence: While this involves taking positive actions to help others, it is more focused on promoting good and providing benefits. Non-maleficence is the specific duty to prevent harm, which is the primary intent of fall safety measures. Beneficence is often the "doing good" side of the same coin, but prevention of injury is non-maleficence.
C. Justice: This ethical concept refers to the fair and equitable distribution of healthcare resources and treatments among all patients. It ensures that every individual has access to the same level of care regardless of their background. Fall precautions for a single patient do not primarily address the systemic allocation of medical goods.
D. Veracity: This principle refers to the nurse's obligation to tell the truth and be honest with patients. It is fundamental to the informed consent process and the establishment of a trusting therapeutic relationship. While honesty is vital, it does not directly relate to the physical safety interventions used to prevent patient falls.
