It filters harmful substances from the body.

It drains capillary blood from the circulation.

It produces protective antibodies.

It manufactures T lymphocytes.

Answer and Explanation

The Correct Answer is A

A. It filters harmful substances from the body: The lymphatic system plays a crucial role in filtering lymph fluid and removing harmful substances, such as pathogens and toxins, through lymph nodes.

B. It drains capillary blood from the circulation: The lymphatic system does not directly drain capillary blood; instead, it collects interstitial fluid and returns it to the bloodstream.

C. It produces protective antibodies: Antibodies are produced by B lymphocytes in the immune system, not directly by the lymphatic system itself.

D. It manufactures T lymphocytes: While the lymphatic system is involved in the maturation and function of T lymphocytes, their manufacture occurs in the bone marrow and thymus rather than the lymphatic system itself.

Correct Answer is B

Explanation

A. Ears: Evaluation of the ears is primarily concerned with hearing and balance, which involve cranial nerves such as VIII (Vestibulocochlear), not IX, X, and XII.

B. Mouth and throat: Cranial nerves IX (Glossopharyngeal), X (Vagus), and XII (Hypoglossal) are assessed through the examination of the mouth and throat. CN IX and X are evaluated by checking the gag reflex and the ability to swallow, while CN XII is assessed by examining tongue movements.

C. Head and face: The assessment of the head and face generally involves cranial nerves V (Trigeminal) and VII (Facial), which control facial sensation and movement, rather than IX, X, and XII.

D. Mental status examination: While mental status is crucial for overall health assessment, it does not specifically target cranial nerves IX, X, and XII.

A. Secondary Prevention B. Primary Prevention C. Tertiary Prevention D. Educational Prevention

Correct Answer is B

Explanation

A. Secondary Prevention: This level focuses on early detection and treatment of diseases, such as screenings or exams, rather than promoting healthy behaviors.

B. Primary Prevention: This level involves strategies to prevent disease before it occurs, including promoting healthy lifestyles through exercise and nutrition.

C. Tertiary Prevention: This level aims to manage and improve quality of life for individuals with existing diseases to prevent complications, rather than preventing disease onset.

D. Educational Prevention: This term is not a standard classification in prevention levels; it refers to educational efforts but does not specifically align with the established levels of prevention.
