A nurse is caring for a client who is scheduled for a Tensilon challenge test to check for myasthenia gravis. Which of the following findings should the nurse identify as a positive result?
Muscle strength becomes temporarily stronger.
A "pill-rolling" tremor appears.
Electrical charge in the muscle increases in intensity.
Muscle strength shows no change.
The Correct Answer is A
A. A positive result in a Tensilon test is indicated by a temporary improvement in muscle strength following the administration of edrophonium (Tensilon), confirming the diagnosis of myasthenia gravis.
B. A "pill-rolling" tremor is associated with Parkinson's disease, not myasthenia gravis, and is not relevant to this test.
C. While muscle electrical activity can be assessed in other tests, the Tensilon test specifically evaluates muscle strength changes, not electrical charge intensity.
D. No change in muscle strength would suggest a negative result for myasthenia gravis, indicating that the test did not confirm the diagnosis.

Correct Answer is D
Explanation
A. Black cohosh is primarily used for menopausal symptoms and does not have benefits for peripheral arterial disease.
B. Echinacea is commonly used to boost the immune system but is not effective for improving circulation or walking distance in peripheral arterial disease.
C. Saw palmetto is mainly used for urinary symptoms related to benign prostatic hyperplasia and does not address the symptoms of peripheral arterial disease.
D. Ginkgo biloba has been shown to improve blood circulation and may help increase pain-free walking distance in clients with peripheral arterial disease, making it the most suitable option.
Correct Answer is D
Explanation
A. While coronary arteries may change with age, the increased elasticity does not lead to insufficient oxygen; rather, it can affect their ability to respond to increased demand.
B. Weakening of the heart can contribute to heart failure but is not a direct explanation for how coronary artery disease causes angina.
C. Dilation of coronary arteries typically does not cause manifestations in coronary artery disease; instead, it is the narrowing (stenosis) that leads to issues.
D. Decreased diameter of the coronary arteries due to atherosclerosis is the primary issue in coronary artery disease, which leads to inadequate blood supply, oxygen, and nutrients to the heart muscle, causing symptoms like angina.
