    Which system protects the body bacterial invasion and dehydration?

    • Nervous

    • Integumentary

    • Urinary

    • Cardiac

    Correct Answer
    A. Integumentary
    Explanation
    The integumentary system protects the body from bacterial invasion and dehydration. It includes the skin, hair, nails, and sweat glands, which form a barrier against pathogens and help to retain moisture in the body. The skin's outermost layer, the epidermis, acts as a physical barrier to prevent the entry of bacteria and other harmful substances. Additionally, the sweat glands produce sweat, which helps to cool the body and maintain hydration. Therefore, the integumentary system plays a vital role in protecting the body from bacterial invasion and dehydration.

    Evaluation of the endocrine system involves:

    • Blood gas studies

    • Spinal fluid analysis

    • Hormone determinations

    • Drug monitoring

    Correct Answer
    A. Hormone determinations
    Explanation
    The evaluation of the endocrine system involves hormone determinations. This is because the endocrine system is responsible for producing and regulating hormones in the body. By measuring hormone levels, healthcare professionals can assess the function of the endocrine system and identify any imbalances or abnormalities. This can help in diagnosing and managing endocrine disorders such as diabetes, thyroid disorders, and adrenal insufficiency. Blood tests are commonly used to measure hormone levels, and specific hormone tests may be ordered based on the suspected condition. Spinal fluid analysis, blood gas studies, and drug monitoring are not directly related to evaluating the endocrine system.
