Correct Answer: B

Rationale: Hypervigilance is a common manifestation of PTSD characterized by heightened alertness and fear of danger. This heightened state of awareness can lead to irritability, difficulty concentrating, and sleep disturbances. Choices A, C, and D are incorrect. Hyperactivity is not typically associated with PTSD; restlessness may be present but is not the primary manifestation, and avoidance of social situations is more commonly seen in conditions like social anxiety disorder rather than PTSD.

Correct Answer: A

Rationale: Correctly assessing a patient with potential pneumonia involves listening to lung sounds and monitoring oxygen saturation. Lung sounds can reveal abnormal breath sounds associated with pneumonia, such as crackles or diminished breath sounds. Oxygen saturation monitoring helps in detecting respiratory distress, a common complication of pneumonia. Monitoring for fever and sputum production (Choice B) is important but not as specific as assessing lung sounds and oxygen saturation. Auscultating heart sounds and checking for cyanosis (Choice C) are not primary assessments for pneumonia. Monitoring for chest pain and administering oxygen (Choice D) are relevant interventions but do not address the initial assessment of pneumonia.

Correct Answer: A

Rationale: The most appropriate intervention for a client with dementia at risk of falls is to use a bed exit alarm to notify staff of attempts to leave the bed. This intervention allows for timely assistance and prevents falls. Raising all four side rails (Choice B) can lead to entrapment or agitate the client. Encouraging frequent ambulation with assistance (Choice C) may not be suitable for a client at high risk of falls. Using restraints (Choice D) should be avoided as they can increase agitation, risk of injury, and have ethical implications.

Correct Answer: A

Rationale: The correct answer is A: History of gastrointestinal bleeding. Aspirin therapy is contraindicated in clients with a history of gastrointestinal bleeding because aspirin can further increase the risk of bleeding. Option B, prothrombin time of 12 seconds, is within the normal range and does not indicate a concern related to aspirin therapy. Option C, platelet count of 180,000/mm�, is also within the normal range and does not suggest a need for reporting to the provider in the context of aspirin therapy. Option D, creatinine level of 1.0 mg/dL, is within the normal range and is not directly related to aspirin therapy in this scenario.

Correct Answer: A

Rationale: Correct answer: Administering antibiotics and providing oxygen therapy are essential in managing pneumonia. Antibiotics help treat the infection caused by bacteria, while oxygen therapy improves lung function. Choice B is incorrect because bronchodilators may not be the primary treatment for pneumonia. Choice C is not the priority in pneumonia management, although fluids and rest are important for recovery. Choice D is also not a primary intervention in pneumonia management.
