While patient Sarah is confined in the hospital, the safety measure to be observed by the nurses is prevention from fall. This is brought about by the patient being prone to fracture as a result of________.

Correct Answer: B

Rationale: The correct answer is B: osteoporosis. Osteoporosis is a condition characterized by weakened bones, making individuals more susceptible to fractures, especially with minor trauma or falls. In the context of a patient prone to fractures, nurses should be particularly cautious about fall prevention. A: The aging process alone does not necessarily lead to an increased risk of fractures. While aging is a risk factor for osteoporosis, it is not the direct cause of fractures in this case. C: Changes in vision can contribute to an increased risk of falls, but it is not the primary reason for the patient being prone to fractures in this scenario. D: Hematologic conditions may affect bone health, but they are not typically the primary cause of increased fracture risk in patients.

Correct Answer: A

Rationale: The correct answer is A: Rotator cuff tear. The presentation of acute shoulder pain and limited range of motion after a fall onto an outstretched hand, along with tenderness over the greater tuberosity and pain with passive abduction and external rotation, is classic for a rotator cuff tear. The mechanism of injury and physical exam findings are consistent with this condition. B: Glenohumeral dislocation typically presents with a visibly deformed shoulder and loss of normal shoulder contour. C: Acromioclavicular joint separation would present with tenderness over the AC joint rather than the greater tuberosity, and typically involves a history of direct trauma to the shoulder. D: Proximal humerus fracture would present with more diffuse shoulder pain and swelling, and not specific tenderness over the greater tuberosity.

Correct Answer: B

Rationale: The correct answer is B: Smoking cessation. Smoking is the leading cause of lung cancer, so quitting smoking is crucial in preventing and improving survival rates. Smoking cessation reduces the risk of developing lung cancer and improves treatment outcomes. High-dose chemotherapy (A) may be part of the treatment plan, but quitting smoking is more impactful. Early bronchoscopy (C) and early detection (D) are important, but without addressing the root cause (smoking), the survival rates will not significantly increase.

Correct Answer: A

Rationale: The correct answer is A: Active artificial immunity. This is because the person's immune system is actively stimulated by the vaccine to produce antibodies against Covid-19. It is considered artificial because it is acquired through vaccination rather than natural exposure to the disease. B: Active natural immunity is incorrect because it refers to immunity acquired through natural exposure to the disease. C: Passive natural immunity is incorrect because it refers to temporary immunity passed from mother to baby through breast milk or placenta. D: Passive artificial immunity is incorrect because it refers to receiving pre-formed antibodies, such as through an injection of antibodies rather than the body producing them itself.

Correct Answer: A

Rationale: The correct answer is A: Pulmonary embolism. This is the most likely cause of the symptoms based on the presentation of chest pain, dyspnea, hemoptysis, and a mismatched defect on the V/Q scan. A pulmonary embolism occurs when a blood clot travels to the lungs, causing a blockage in the pulmonary artery. This can lead to symptoms like chest pain, shortness of breath, and coughing up blood. The V/Q scan showing a mismatched defect indicates a ventilation-perfusion mismatch, which is a classic finding in pulmonary embolism. Pericarditis (B), acute myocardial infarction (C), and aortic dissection (D) typically present with different sets of symptoms and do not match the V/Q scan findings in this case.

Correct Answer: D

Rationale: The correct answer is D because health education aims to empower individuals and families to develop skills and literacy in health. This enables them to make informed decisions and take control of their health. By improving their health literacy, they can better understand health information and navigate the healthcare system effectively. This goal aligns with promoting health behavior change and long-term wellness. A: Studying life history is not a primary goal of health education and does not directly contribute to improving health outcomes. B: Identifying weaknesses may be a part of health assessment, but the main goal is to empower individuals with skills and knowledge to improve their health. C: While lifestyle changes may be necessary for better health, the goal of health education is to provide individuals with the tools to make these changes, not to impose drastic transformations.

Correct Answer: C

Rationale: The correct answer is C: Cells die. In Alzheimer's disease, there is a progressive degeneration of brain cells, leading to cell death. This results in a loss of important brain functions such as memory, cognition, and eventually, bodily functions. The atrophy of the brain stem (choice A) is not a characteristic feature of Alzheimer's. Fluid buildup (choice B) is not a primary mechanism of the disease. Tissue swelling (choice D) is not typically associated with the progression of Alzheimer's; rather, there is a gradual loss of brain tissue due to cell death.

Correct Answer: B

Rationale: The correct answer is B: Persons who have the disease. Sensitivity measures how well a test correctly identifies individuals who have the disease (true positives). It is essential in determining the test's ability to detect the presence of the disease accurately. Choices A, C, and D are incorrect because sensitivity focuses on correctly identifying individuals who have the disease, not those with symptoms, those without the disease, or those with a diagnosis of the disease.

Correct Answer: C

Rationale: The correct answer is C: Anaphylaxis. Anaphylaxis is the MOST severe form of an allergic reaction, including latex allergy. It is a systemic, potentially life-threatening reaction that can involve multiple organ systems. Symptoms can include difficulty breathing, swelling of the throat, a rapid drop in blood pressure, and cardiovascular collapse. Pruritus, erythema, and swelling (choice A) are common symptoms of allergic reactions but not specific to anaphylaxis. Asthma (choice B) can be a manifestation of latex allergy but is not the most severe form. Blisters and other skin lesions (choice D) are not typical of anaphylaxis but can occur in some cases of contact dermatitis from latex exposure.
