Rationale: Involution refers to the process of the uterus returning to its nonpregnant state after childbirth. During pregnancy, the uterus undergoes significant changes and enlarges to accommodate the growing fetus. After childbirth, the uterus begins to contract, leading to a decrease in its size and a return to its pre-pregnant state. This process involves the shedding of the excess endometrial tissue and the reduction of the size of the uterine muscle fibers. It is a normal and essential process for postpartum recovery. Failure of the uterus to undergo proper involution is known as subinvolution, which can lead to complications such as postpartum hemorrhage.

This approach considers the patient's responsibilities and can help her organize her time effectively to ensure she gets adequate rest while managing her studies. It acknowledges the importance of rest without completely disregarding the patient's other commitments, ultimately fostering a balanced approach to self-care. This intervention is patient-centered and collaborative, empowering the patient to take an active role in prioritizing rest alongside her educational responsibilities.

Rationale: Osteoarthritis in the hip joint can lead to weakness or dysfunction in the hip abductor muscles, causing a Trendelenburg gait. This gait abnormality is characterized by a dropping of the pelvis on the opposite side of the affected hip during weight-bearing on the affected leg. It is a common clinical manifestation of hip osteoarthritis due to the muscle weakness and altered mechanics in the hip joint. Baker's cyst is associated with knee osteoarthritis, Heberden's nodes are commonly seen in osteoarthritis of the fingers, and Swan-neck deformity is typically seen in rheumatoid arthritis, not osteoarthritis.

Correct Answer: C

Rationale: Nurse Gina has to consider that most of the elderly are dependent on others financially. This is an important factor to take into account when planning and providing care for elderly patients. Many elderly individuals rely on financial assistance from family members, government programs, or retirement funds. Understanding the financial status of elderly patients helps nurses like Gina provide adequate care and support to meet their needs effectively. This can involve coordinating with social services or financial assistance programs to ensure that the patients' financial concerns are addressed along with their healthcare needs.
