A normal age-related change for the immune and lymphatic systems is the

Correct Answer: A

Rationale: The correct answer is A because it is a well-documented fact that the immune system tends to weaken with age, leading to decreased effectiveness in fighting off infections and diseases. This decline is due to factors such as thymus shrinkage and decreased T-cell function. Antibody response speeding up (B) and increased T-cells (C) are not typical age-related changes. Response to vaccines increasing (D) is also unlikely as older individuals usually have a weakened immune response to vaccines.

Correct Answer: C

Rationale: The correct answer is C (15 hours) because federal regulations mandate nursing assistants to complete 12 hours of continuing education annually. This requirement ensures that nursing assistants are up-to-date with the latest practices, guidelines, and skills necessary to provide high-quality care to patients. Explanation for other choices: A (10 hours): This choice is incorrect as it does not meet the federal requirement of 12 hours. B (12 hours): While this choice aligns with the federal requirement, it falls short of the correct answer of 15 hours. D (18 hours): This choice exceeds the federal requirement and is therefore incorrect.

Correct Answer: C

Rationale: The correct answer is C because battery in legal terms refers to the intentional and unauthorized touching of another person without their consent. This action constitutes a violation of the person's physical autonomy and is legally considered a form of harm. Choices A, B, and D do not align with the definition of battery and are incorrect. Choice A refers to financial exploitation, choice B refers to verbal abuse, and choice D refers to a breach of confidentiality, none of which are related to the legal concept of battery.

Correct Answer: A

Rationale: Verbal communication involves the use of words to convey a message. Sending a text message involves typing and sending written words, making it a clear example of verbal communication. Crossing arms (choice B) and tapping feet (choice C) are non-verbal cues, while nodding (choice D) is a non-verbal gesture indicating agreement. These choices do not involve the use of words, unlike sending a text message (choice A), which directly uses language for communication.

Correct Answer: C

Rationale: The correct answer is C: Birth trauma. Cerebral palsy is a neurological disorder that affects movement and posture, often caused by damage to the developing brain before, during, or shortly after birth. Birth trauma, such as oxygen deprivation during delivery, can lead to cerebral palsy. Vehicular accidents (A), accidents after the age of three (B), and communicable diseases (D) are not direct causes of cerebral palsy as they do not typically result in brain damage during the critical developmental period around birth.
