The nurse is caring for a patient who presents to the emergency department with right-sided weakness and dysphasia. Which type of stroke would the nurse suspect?
Transient ischemic attack
Basilar artery syndrome
Left middle cerebral artery syndrome
Right middle cerebral artery syndrome
The Correct Answer is C
A. Transient ischemic attack (TIA): A TIA might cause transient symptoms similar to a stroke, including weakness and dysphasia, but it would not explain why the symptoms are localized to the right side of the body. Additionally, TIA symptoms typically resolve within 24 hours.
B. Basilar artery syndrome: This type of stroke affects the brain stem, resulting in symptoms such as double vision, vertigo, and ataxia, rather than localized right-sided weakness and dysphasia.
C. Left middle cerebral artery syndrome: The left middle cerebral artery (MCA) supplies blood to the left hemisphere of the brain, including areas that control language and motor function on the right side of the body. Thus, an infarct in this area often leads to right-sided weakness and dysphasia, making it the most likely suspect.
D. Right middle cerebral artery syndrome: This would typically result in left-sided weakness and possibly neglect, but not right-sided symptoms

Correct Answer is ["B","D","E"]
Explanation
A. Heberden nodes: These are bony swellings commonly seen in osteoarthritis, particularly affecting the distal interphalangeal joints of the fingers, not typically associated with rheumatoid arthritis (RA).
B. Early morning stiffness: RA is characterized by prolonged morning stiffness lasting more than 30 minutes, which improves with activity, distinguishing it from the short-lived stiffness seen in osteoarthritis.
C. Pain increasing by activity: This is more characteristic of osteoarthritis, where joint pain typically worsens with use and activity. RA pain often improves with movement as the joints "warm up."
D. Autoimmune disease: RA is an autoimmune condition where the body's immune system attacks its own tissues, leading to inflammation and joint damage.
E. Low-grade fever: Low-grade fever can be a systemic symptom of RA due to the autoimmune inflammatory process, which is not a feature of osteoarthritis.
Correct Answer is D
Explanation
A. Lying prone as prescribed: While lying prone can help prevent hip flexion contractures, it is not directly related to promoting ambulation. It is typically part of post-operative care to prevent contractures in the hip, but ambulation primarily depends on upper body strength and prosthetic training.
B. Maintaining residual limb elevation: Elevation of the residual limb is important immediately postoperatively to reduce swelling, but prolonged elevation can lead to contractures, which can hinder ambulation.
C. Promoting coordination exercises: Coordination is important, but for ambulation, building strength, especially in the upper body, is crucial to support the use of assistive devices and maintaining balance.
D. Building upper body strength: This is essential for promoting ambulation as it helps the patient in using assistive devices like crutches or walkers and in transferring safely. Upper body strength is crucial for balance and mobility with a prosthetic limb.
