Which of the following is a local sign of infection?

Correct Answer: A

Rationale: A local sign of infection refers to symptoms that are specific to the area of infection. Swelling, heat, pain, and redness near the infected site are examples of local signs. In the context of infection, swelling occurs due to an accumulation of fluid and immune cells at the site of infection. Rapid pulse, fever, and high white blood count are more systemic responses to infection and not specific local signs. Rapid pulse can indicate systemic distress or sepsis, fever is a systemic response to infection, and high white blood count is a laboratory finding that suggests an immune response but is not a direct sign of infection at a specific site.

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: B

Rationale: The correct answer is 'With treatment, this condition can be cured.' The treatment for herpes simplex virus (HSV) is symptomatic and palliative, aimed at managing symptoms rather than curing the infection. HSV is highly contagious, so sexual contact should be avoided during active outbreaks to prevent transmission. Many patients experience a tingling sensation in the skin before an active outbreak, known as a prodrome. Educating the patient that the condition is not curable but manageable with treatment is vital to set realistic expectations and promote proper management of the disease.

Correct Answer: A

Rationale: A mitten on the hands to prevent scratching is considered a protective device because its primary purpose is to protect the patient from harming themselves by scratching. It does not restrict the patient's movement. Choice B, a mitten on the hands to prevent the person from pulling their IV out, is considered a restraint as it limits the patient's movement. Choice C, a side rail to prevent the patient from falling, is also a protective device as it aims to keep the patient safe by providing support and preventing falls. Choice D, a soft wrist restraint to prevent the patient from pulling their IV tubing, is a type of restraint as it restricts the patient's movement to prevent them from interfering with medical equipment.

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: Prevention of lung disease requires the use of appropriate protective equipment such as masks to reduce exposure to inhaled dust, which is a significant risk factor for lung disease. Teaching about symptoms of lung disease, treating workers with pulmonary fibrosis, and monitoring for coughing and wheezing are important actions for early recognition and treatment of lung disease. However, the most effective strategy to prevent lung damage in this scenario is to require the use of protective equipment to minimize exposure to harmful substances.

Correct Answer: B

Rationale: When escorting a patient to the operating room on a stretcher, it is crucial to secure a safety belt or strap on the patient to prevent falls during the transfer. This safety measure is not considered a restraint but a necessary precaution. Lowering the bed position is not necessary; in fact, the bed should be in a high position to align with the stretcher. Locking the wheels of the stretcher is essential to prevent accidents during patient transfer. Therefore, the correct action to prevent falls while moving a patient to the operating room is to use a safety belt or strap on the patient throughout the escort.

Correct Answer: C

Rationale: The nurse is considered to have a latent TB infection and should be treated with INH daily for 6 to 9 months. The four-drug therapy would be appropriate if the nurse had active TB. TB skin testing is not done for individuals who have already had a positive skin test. BCG vaccine is not used in the United States for TB and would not be helpful for this individual, who already has a TB infection.

Correct Answer: C

Rationale: The correct answer is 'Once symptoms disappear there is no longer an illness'. In Vietnamese culture, there is a belief that once symptoms go away, the illness is no longer present and does not require further treatment. This is crucial to understand when educating Vietnamese patients about completing their antibiotic regimen. Choices A and B (cupping and coining) are traditional Vietnamese healing practices that are not directly related to completing antibiotic therapy. Choice D, about households consisting of multiple generations, is not directly relevant to the completion of antibiotic treatment for pneumonia in this context.
