Sinusitis is caused by:

Correct Answer: D

Rationale: Sinusitis can be caused by bacteria, viruses, or fungi. While bacterial infections are the most common cause, viral or fungal infections can also lead to sinusitis. Therefore, the correct answer is 'Any of the above.' Choices A, B, and C are incorrect because they only represent individual causes of sinusitis, whereas choice D encompasses all possible causes.

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: C

Rationale: All choices are hazards of immobility, but only calcium loss from the bones is a skeletal system impairment that results from immobility. Contractures are muscle shortening due to prolonged positioning, which affects the muscular system. Constipation is a gastrointestinal issue. Catabolism is a metabolic process, not specific to the skeletal system.

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.

Correct Answer: B

Rationale: This patient is at great risk for skin breakdown due to the presence of three specific risk factors: confusion, lethargy, and items in the bed. While confusion puts the patient at risk for falls, confusion and lethargy together may lead to a lack of mobility. However, skin breakdown is the primary concern in this scenario as it is associated with all three risk factors - confusion, lethargy, and the presence of items in the bed. Therefore, the correct answer is 'Skin breakdown'.

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: 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: A

Rationale: Mary Eden, due to her muscular frailty, is at risk of falling. The most effective preventive measure in this case would be physical therapy focusing on muscle strengthening exercises. Strengthening exercises can help improve her muscle tone and stability, reducing the risk of falls. While range of motion exercises may be beneficial, they may not directly address her muscular frailty and stability concerns as effectively as muscle strengthening exercises. Occupational therapy aims to help individuals with activities of daily living and functional tasks, not confusion. Medications to induce more sleep can actually increase the risk of falls due to potential side effects like dizziness or disorientation, rather than preventing falls.

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.
