Correct Answer: A

Rationale: Rheumatoid arthritis is a common cause of secondary osteoporosis. Chronic inflammation in rheumatoid arthritis can lead to bone loss due to increased osteoclast activity and decreased bone formation. Patients with rheumatoid arthritis are at an increased risk for developing osteoporosis, resulting in decreased bone density and increased fracture risk. Monitoring and managing bone health is an important aspect of care for individuals with rheumatoid arthritis to help prevent osteoporosis-related complications.

Correct Answer: B

Rationale: Cardiogenic shock is a life-threatening condition where the heart is unable to pump enough blood to meet the body's demands. Monitoring the patient's cardiac index, which is a measure of cardiac output adjusted for body surface area, can help detect the risk of developing cardiogenic shock. A decrease in cardiac index would indicate a decrease in the heart's ability to effectively pump blood, putting the patient at risk for cardiogenic shock. Monitoring cardiac index is essential in assessing cardiac function and guiding interventions to prevent the progression to cardiogenic shock. The other factors listed may provide important information in assessing the patient's condition, but specifically in detecting the risk of developing cardiogenic shock, monitoring the cardiac index is crucial.

Correct Answer: B

Rationale: Metformin is a commonly prescribed medication for the treatment of type 2 diabetes mellitus. One of the rare but serious adverse effects associated with metformin use is lactic acidosis. Lactic acidosis results from the buildup of lactic acid in the bloodstream, leading to symptoms such as weakness, rapid breathing, abdominal pain, and muscle pain. Lactic acidosis can be life-threatening and requires immediate medical attention. It is important for patients taking metformin to be aware of the signs and symptoms of lactic acidosis and seek immediate medical help if they experience any of these symptoms. Regular monitoring of kidney function is crucial in patients taking metformin to reduce the risk of lactic acidosis.

Correct Answer: A

Rationale: The best result of a health education process is when it successfully influences and changes behaviors towards positive health outcomes. Providing new input, updating others, and information transfer are important components of health education, but the ultimate goal is to effect behavior change. When individuals are able to internalize and apply the knowledge gained from health education to make healthier choices in their daily lives, the process can be considered successful. Therefore, the most desirable outcome of health education is the behavioral change that leads to improved health and well-being.

Correct Answer: C

Rationale: Periodontitis is the dental condition characterized by inflammation and destruction of the supporting structures of the teeth, including the gingiva (gums), periodontal ligament, and alveolar bone. It is usually caused by untreated gingivitis, where plaque buildup along the gumline leads to bacterial infection and inflammation, resulting in destruction of the tissues that support the teeth. If left untreated, periodontitis can lead to tooth loss and other complications. Gingivitis, on the other hand, is inflammation of the gums without involvement of the supporting structures, while dental caries refer to tooth decay or cavities in the enamel. Dental abscess is a localized collection of pus caused by a bacterial infection.
