A patient arrives in the emergency department at 0200 exhibiting signs and symptoms of a stroke. The patient went to bed at 2300 and was "feeling fine" but woke up at 0100 to go to the restroom and fell on the way there. The CT scan shows a hemorrhagic stroke. For what reason would tPA therapy be withheld?

tPA is not delivered for hemorrhagic stroke.

The total effects of ischemia are not currently known.

Too much time has passed since the symptoms began.

The patient's symptoms have progressed too quickly.

Answer and Explanation

The Correct Answer is A

A. tPA is not delivered for hemorrhagic stroke: This is correct. tPA is a thrombolytic medication used for ischemic strokes, not haemorrhagic strokes, as it would exacerbate bleeding.
B. The total effects of ischemia are not currently known: While assessing the extent of ischemia is important for ischemic stroke, it is irrelevant here because the stroke is hemorrhagic.
C. Too much time has passed since the symptoms began: The time window is important for tPA in ischemic strokes, but in this case, the type of stroke (haemorrhagic) is the determining factor.
D. The patient's symptoms have progressed too quickly: The progression of symptoms does not affect the decision to use tPA; the contraindication is solely due to the hemorrhagic nature of the stroke.

Correct Answer is C

Explanation

A. Incontinence (bowel or urinary): While incontinence may occur in stroke patients, it is not the primary concern for someone with hemianopsia, a visual impairment.
B. Impaired skin integrity: Although this is important, particularly for immobile patients, it is not directly related to hemianopsia.
C. Disturbed sensory perception: Hemianopsia results in the loss of half the field of vision in one or both eyes, leading to disturbed sensory perception. This is a priority because it directly affects the patient's ability to navigate their environment safely.
D. Imbalanced nutrition: Although important, this is not the immediate concern related to hemianopsia.

A. Monitor blood glucose levels. B. Lifestyle modifications and medication adherence will not prevent blindness, C. Lifestyle modifications can prevent strokes. D. End organ damage is inevitable because of microvascular changes that occur. E. Take medications as ordered.

Correct Answer is ["A","C","E"]

Explanation

A. Monitor blood glucose levels: Patients with diabetes need to keep their blood glucose levels under control to prevent complications, including those that can exacerbate hypertension or lead to cardiovascular problems.
B. Lifestyle modifications and medication adherence will not prevent blindness: This is incorrect. Proper management of diabetes through lifestyle changes and medication adherence can help prevent complications like diabetic retinopathy, which can lead to blindness.
C. Lifestyle modifications can prevent strokes: Effective management of diabetes and hypertension through lifestyle changes (diet, exercise, smoking cessation) can significantly reduce the risk of strokes and other cardiovascular events.
D. End organ damage is inevitable because of microvascular changes that occur: This is misleading. While microvascular changes are a risk in diabetes, proper management and lifestyle modifications can greatly reduce the risk and progression of end-organ damage.
E. Take medications as ordered: Adherence to prescribed medications is crucial for controlling both blood glucose and blood pressure, reducing the risk of complications such as stroke, heart disease, and kidney damage.
