Correct Answer is A
Explanation
A. A positive result in a Tensilon test is indicated by a temporary improvement in muscle strength following the administration of edrophonium (Tensilon), which confirms the diagnosis of myasthenia gravis.
B. A "pill-rolling" tremor is associated with Parkinson's disease and is not a relevant finding in myasthenia gravis or the Tensilon test.
C. The Tensilon test assesses muscle strength rather than electrical charge in the muscle; therefore, an increase in electrical activity is not a relevant measure for this test.
D. No change in muscle strength indicates a negative result for myasthenia gravis, suggesting that the test did not confirm the diagnosis.
Correct Answer is B
Explanation
A. Shopping for shoes in the morning is not recommended, as feet tend to swell later in the day, and shoe fitting should account for potential swelling.
B. Incorporating walking into the daily routine helps improve circulation and can aid in managing peripheral vascular disease by promoting blood flow in the legs.
C. Elevating the legs might decrease circulation and is not advised for clients with peripheral vascular disease, as it can reduce blood flow to the extremities.
D. Knee-length stockings can restrict circulation, especially if they are too tight, and should be avoided to promote proper blood flow in clients with this condition.
