Correct Answer: A

Rationale: The correct answer is A: Moisture strengthens the effects of warm and cold applications by facilitating heat transfer. When moisture is present, it enhances the conduction of heat/cold to the body, intensifying the therapeutic effects. This increased heat/cold transfer helps in achieving the desired outcomes more efficiently. Explanation of Incorrect Choices: B: Moisture does not reduce the effects of warm and cold applications; it actually enhances them. C: Moisture does not directly affect the likelihood of causing injury; proper application technique is key to prevent injury. D: Moisture does not necessarily allow applications to be applied for a longer time; the duration of application should be based on individual needs and treatment goals.

D: Nursing assistants do not prescribe medical devices; this is the responsibility of healthcare providers.

Correct Answer: B

Rationale: The correct answer is B: Some memory loss occurs. As people age, it is common to experience mild memory decline due to changes in brain structure and function. This is a normal part of the aging process and does not necessarily indicate a serious cognitive issue. Choices A, C, and D are incorrect because aging typically does not lead to speeding up of responses and reflexes, increased sensitivity of nerve endings in the skin, or improvement in senses such as vision and taste. These changes are more likely to occur due to external factors or individual differences rather than normal age-related changes in the nervous system.

Option C is incorrect as psychosurgery is not a standard treatment for anxiety disorders. Option D is incorrect because electroconvulsive therapy is typically used for severe depression, not anxiety disorders.
