Order: Infuse 1,000 mL NS over 8 hours using a 10 gtt/mL set. Calculate the flow rate in drops per minute.

Rationale:

A. One of the hallmark early signs of MS is optic neuritis, which occurs when demyelination affects the optic nerve. This results in sudden or subacute vision loss in one eye, often accompanied by pain with eye movement. Visual symptoms may be transient or partially recover, but repeated episodes are common. Recognizing optic neuritis is important for early diagnosis and initiation of disease-modifying therapy.

B. MS commonly affects cranial nerves III, IV, and VI or their central pathways, leading to ocular motor dysfunction. This can cause: Diplopia (double vision) due to extraocular muscle weakness or impaired nerve conduction, Blurred vision from optic nerve involvement or demyelination in visual pathways, Nystagmus in some patients
These symptoms contribute to difficulty reading, driving, and performing fine visual tasks and often worsen with fatigue or heat (Uhthoff’s phenomenon).

C. Bradykinesia is a slowness of voluntary movement seen in Parkinson’s disease, not MS. While MS can cause motor weakness, spasticity, or coordination deficits, true bradykinesia is absent. Confusing the two may lead to misdiagnosis.

D. Fatigue is one of the most common and disabling symptoms of MS, affecting up to 80% of patients. It can be primary (from demyelination and CNS changes) or secondary (from sleep disturbance, depression, infection, or heat). Fatigue often: Worsens in the afternoon or after activity, Impairs ADLs, work performance, and quality of life and Requires energy conservation strategies, pacing, and sometimes pharmacologic management

E. Depression is common in MS due to a combination of: Neurochemical changes from CNS demyelination and psychological stress of living with a chronic, unpredictable disease
Depression can negatively impact adherence to medications, physical activity, and disease self-management. Screening and early treatment are essential.

Rationale:

A. Lifestyle modifications such as regular physical activity and weight management improve insulin sensitivity and can significantly help control blood glucose levels in type 2 diabetes. This statement reflects accurate understanding of non-pharmacologic management.

B. While many patients with type 2 diabetes initially manage the condition with lifestyle changes and oral medications, insulin may be required if blood glucose is persistently elevated or during times of illness, surgery, or pregnancy. This statement demonstrates a misunderstanding of disease management.

C. Regular blood glucose monitoring allows the patient and healthcare team to assess the effectiveness of diet, exercise, and medications and make timely adjustments. This demonstrates accurate understanding of self-management.

D. Many patients with type 2 diabetes require oral hypoglycemic agents (e.g., metformin, sulfonylureas, SGLT2 inhibitors) to achieve glycemic control. Recognizing the potential need for medications reflects correct knowledge.

E. Nutrition is a cornerstone of diabetes management. Balanced meals, carbohydrate counting, and portion control help prevent blood glucose spikes and support overall health. This statement demonstrates understanding of dietary management strategies.
