A nurse is reinforcing teaching to a client who has arrhythmogenic cardiomyopathy about the risk for sudden cardiac death. Which of the following client statements indicates to the nurse an understanding of the teaching?
"I should ask my son to drive me to the grocery store."
"I am aware that I may develop frequent hiccups."
"I will probably become easily constipated."
"I will avoid competitive recreational sports."
The Correct Answer is D
A. While it may be wise to avoid driving if experiencing symptoms, asking for assistance in general does not specifically address the risk of sudden cardiac death.
B. Frequent hiccups are not a common indication or symptom directly related to arrhythmogenic cardiomyopathy or its risks.
C. Constipation is not directly related to arrhythmogenic cardiomyopathy or the risk of sudden cardiac death.
D. Avoiding competitive recreational sports is critical for clients with arrhythmogenic cardiomyopathy, as these activities can increase the risk of sudden cardiac events due to physical exertion.

Correct Answer is B
Explanation
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 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.
