Answer and Explanation

The Correct Answer is B

A. The ascending tract of the spinal cord transmits sensory information to the brain, but it does not process it; processing occurs in the brain itself.
B. This statement accurately describes the function of the descending tracts, which carry motor commands from the central nervous system (CNS) to the muscles, facilitating movement.
C. Sensory receptors are located in various tissues throughout the body, including the skin, not just in the muscles.
D. Motor neurons are not found in the dermal layer; they are located in the spinal cord and the peripheral nervous system, where they innervate muscles.

Correct Answer is D

Explanation

A. Wearing gloves when removing food from the freezer is appropriate and helps prevent exposure to cold, which can trigger symptoms of Raynaud's phenomenon.
B. Completing a smoking cessation program is beneficial, as smoking can exacerbate symptoms of Raynaud's.
C. Avoiding stressful situations is advisable since stress can trigger vasoconstriction and exacerbate symptoms.
D. Keeping the house at a cool temperature is not recommended, as cold environments can provoke Raynaud's symptoms; the client should aim to maintain a warm environment to minimize triggers.

A. Muscle strength becomes temporarily stronger. B. A "pill-rolling" tremor appears. C. Electrical charge in the muscle increases in intensity. D. Muscle strength shows no change.

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.
