Neurologic Case Study
Patient Profile:
- Age: 68 years
- Gender: Male
- Medical History: Hypertension, Type 2 Diabetes Mellitus
- Medications: Lisinopril, Metformin
- Allergies: None
Chief Complaint: The patient presents to the emergency department (ED) with sudden onset of right-sided weakness and difficulty speaking that began approximately 1 hour prior to arrival.
Which condition is the patient most likely experiencing?
Hypoglycemia
Hemorrhagic stroke
Ischemic stroke
Multiple sclerosis
The Correct Answer is C
Choice A reason: Hypoglycemia typically presents with symptoms such as sweating, trembling, hunger, confusion, and in severe cases, loss of consciousness. The patient's symptoms of sudden right-sided weakness and difficulty speaking are more consistent with a neurological event rather than low blood sugar levels.
Choice B reason: Hemorrhagic stroke involves bleeding within the brain. Although it can present with similar symptoms to ischemic stroke, the diagnostic tests indicate no evidence of hemorrhage. This makes a hemorrhagic stroke less likely.
Choice C reason: Ischemic stroke occurs when a blood clot blocks a blood vessel in the brain, leading to reduced blood flow and oxygen to a part of the brain. The patient's symptoms of sudden right-sided weakness and expressive aphasia are classic signs of an ischemic stroke, and the absence of hemorrhage on the head CT scan supports this diagnosis.
Choice D reason: Multiple sclerosis (MS) is a chronic, progressive disease that affects the central nervous system. It usually presents with episodic neurological symptoms rather than the sudden onset seen in this patient. MS symptoms develop over time and can vary widely, whereas the patient's acute presentation is more indicative of a stroke.

Correct Answer is B
Explanation
Choice A reason: Type 2 diabetes mellitus, while a serious chronic condition, does not directly predispose patients to delirium. Diabetes primarily impacts the body's ability to regulate blood glucose levels, leading to complications such as cardiovascular disease, neuropathy, and nephropathy. However, it is not directly linked to the acute cognitive disturbances seen in delirium unless it leads to severe metabolic derangements, which is less common.
Choice B reason: Alcohol abuse is a significant risk factor for the development of delirium, especially in ICU patients. Chronic alcohol use can lead to a condition known as delirium tremens (DTs) during withdrawal, characterized by severe agitation, confusion, hallucinations, and autonomic hyperactivity. Patients with a history of alcohol abuse may have altered brain chemistry and neurotransmitter imbalances that predispose them to delirium when stressed by illness or surgery. Moreover, alcohol abuse can lead to liver dysfunction, nutritional deficiencies (particularly thiamine), and other systemic issues that further exacerbate the risk.
Choice C reason: Anxiety can exacerbate stress and discomfort in a patient but is not a primary causative factor for delirium. Anxiety may contribute to an increased sense of fear or confusion, especially in an ICU setting. However, it does not cause the profound disruption in cognitive function, attention, and awareness that characterizes delirium.
Choice D reason: Impaired communication might be a consequence or symptom seen in patients with delirium, but it is not a root cause. Patients with pre-existing communication difficulties might struggle more to express symptoms or needs, which could complicate care, but it does not inherently lead to the onset of delirium. Effective communication strategies and aids can help manage these challenges but do not address the underlying neurological changes seen in delirium.
Correct Answer is B
Explanation
Choice A reason: Nursing supervisors generally oversee nursing staff and ensure that patient care standards are being met, but they are not primarily responsible for developing individualized plans of care.
Choice B reason: Registered nurses (RNs) are trained and licensed to develop individualized plans of care that include nursing diagnoses, interventions, and outcomes. They work closely with patients to understand their needs and create a plan that supports their health goals, including self-management care.
Choice C reason: Health care providers, such as medical doctors (MDs) or nurse practitioners (NPs), are responsible for diagnosing and treating medical conditions, but the development of detailed nursing care plans is typically outside their primary scope of practice.
Choice D reason: Licensed practical/vocational nurses (LPN/VN) provide basic nursing care and assist with patient care activities, but they do not generally develop comprehensive nursing care plans, which require the higher level of training and education that RNs receive.
