One of the complications of complete bed rest and immobility is which of the following?

Correct Answer: A

Rationale: Plantar flexion, or foot drop, is a common complication of complete bed rest and immobility. This condition occurs due to the weakening of muscles that lift the foot, leading to the foot dragging or being unable to clear the ground during walking. Dorsiflexion refers to moving the foot upwards, which is not a typical complication of immobility. Extension contractures involve the inability to fully extend a joint, while adduction contractures refer to the inability to move a limb away from the body. These types of contractures can also occur with immobility, but they are not specifically associated with foot drop.

Correct Answer: A

Rationale: The correct answer is 'Lymphocyte.' Lymphocytes are the smallest type of white blood cells and play a crucial role in humoral immunity by producing antibodies. Monocytes are actually the largest white blood cells and are involved in phagocytosis rather than humoral immunity. Basophils are a type of granulocyte involved in allergic reactions, and erythrocytes are red blood cells responsible for oxygen transport, not part of the immune system.

Correct Answer: C

Rationale: The most effective action by the nurse to decrease the spread of pertussis in a community setting is to teach patients about the necessity of adult pertussis immunizations. The increased rate of pertussis in adults is often attributed to waning immunity after childhood immunization. Immunization is highly effective in protecting communities from infectious diseases. While teaching about handwashing is important for overall infection control, pertussis is primarily spread through respiratory droplets and contact with secretions. Providing supportive care does not significantly impact the disease course or transmission risk. Encouraging completion of antibiotics may help reduce transmission, but patients likely have already spread the disease by the time the diagnosis is made. Therefore, the emphasis should be on prevention through immunization to reduce the spread of pertussis.

Correct Answer: B

Rationale: The correct answer is 'The patient used IV drugs about 20 years ago.' Any patient with a history of IV drug use should be tested for hepatitis C due to the increased risk of transmission through sharing needles. Blood transfusions given after 1992, when an antibody test for hepatitis C became available, do not pose a risk for hepatitis C. Hepatitis C is not spread by the oral-fecal route, so contaminated food or traveling to countries with poor sanitation are not direct risk factors for hepatitis C.

Correct Answer: B

Rationale: Following stabilization, it is essential to connect Brandon with additional resources to address his addiction. Social services are a crucial collaborative partner in this situation because they have access to community resources that can support Brandon's rehabilitation needs. While law enforcement may be involved in certain situations, their primary role is not to provide rehabilitation services. Narcotics Anonymous is a valuable support group but does not offer the comprehensive services that social services for rehab can provide. A financial counselor may be beneficial for addressing financial concerns, but the priority at this stage is to address Brandon's addiction through appropriate rehabilitation services.
