    The correct answer is 2 hours because repositioning a person every 2 hours helps prevent pressure ulcers or bedsores. This frequent change in position helps relieve pressure on specific areas of the body, improves blood circulation, and reduces the risk of skin breakdown. Repositioning every 2 hours ensures that the person's body weight is evenly distributed and prevents prolonged pressure on any one area. This practice is especially important for individuals who have limited mobility or spend long periods of time in bed or a chair.

    You are often delegated task that involve positioning and repositioning. You need instructions from the

    • A.

      Doctor

    • B.

      Nurse

    • C.

      Licensed practical nurse

    • D.

      None of the above

    Correct Answer
    B. Nurse
    Explanation
    In healthcare settings, tasks involving positioning and repositioning of patients are commonly delegated to nurses. Nurses are responsible for providing direct patient care and ensuring the comfort and safety of patients. They have the knowledge and skills to assess the patient's condition, determine the appropriate positioning techniques, and provide instructions to other healthcare personnel or caregivers. Doctors may provide overall guidance and treatment plans, but they are not typically involved in the day-to-day positioning and repositioning tasks. Licensed practical nurses (LPNs) may also be involved in these tasks, but nurses, in general, have a broader scope of practice and are more likely to be delegated such responsibilities.

    Wet, soiled or wrinkled linens are causes of

    • A.

      Contractures

    • B.

      Pressure ulcers

    • C.

      Arthritis

    • D.

      None of the above

    Correct Answer
    B. Pressure ulcers
    Explanation
    Wet, soiled, or wrinkled linens can contribute to the development of pressure ulcers. When linens are wet, they can increase the friction and shear forces on the skin, making it more susceptible to damage. Soiled linens can harbor bacteria and increase the risk of infection, which can further complicate the healing process of pressure ulcers. Wrinkled linens can create uneven pressure distribution on the skin, increasing the likelihood of pressure ulcers forming. Therefore, these factors can all contribute to the development of pressure ulcers.

      Arthritis

    • B.

      Contractures

    • C.

      Pressure ulcers

    • D.

      None of the above

    Correct Answer
    B. Contractures
    Explanation
    Repositioning, exercise, and activity help prevent contractures. Contractures are the shortening and tightening of muscles, tendons, or other tissues, leading to a loss of mobility. By regularly changing positions, engaging in exercise, and staying active, individuals can maintain joint flexibility and prevent the development of contractures. These measures help to keep the muscles and tendons stretched and prevent them from becoming tight or stiff.

    Persons with heart and respitory disorders usually breathe easier in fowler's position

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Persons with heart and respiratory disorders usually breathe easier in Fowler's position because it helps to improve lung expansion and oxygenation. In this position, the head and upper body are elevated, which reduces the pressure on the chest and allows the diaphragm to move more freely. This helps to increase lung capacity and improve ventilation. Additionally, being in Fowler's position can also help to reduce fluid buildup in the lungs, making breathing easier for individuals with heart and respiratory issues.
