Which one of the following statements concerning massive hemothorax is true?

Correct Answer: D

Rationale: Rationale for Correct Answer (D): 1. Massive hemothorax is characterized by the accumulation of blood in the pleural cavity. 2. In situations with shock and unilateral absent breath sounds, there is a high suspicion for massive hemothorax due to significant blood loss and lung collapse. 3. Prompt recognition and treatment are crucial to prevent further complications and stabilize the patient. 4. Immediate interventions such as thoracostomy tube placement may be necessary to evacuate the blood and reexpand the lung. 5. Therefore, choice D is the correct answer as it highlights key clinical features and emphasizes the importance of early diagnosis and management. Summary of Incorrect Choices: A: Massive hemothorax can also be caused by penetrating trauma, not just blunt trauma. B: Pneumothorax involves air accumulation in the pleural cavity, which is different from blood accumulation in hemothorax. C: Delaying treatment for an upright chest x-ray may compromise the patient's condition as

Correct Answer: D

Rationale: The correct initial diagnostic study for evaluating the urinary tract in this patient is "Retrograde urethrography" (Choice D). Rationale: 1. Retrograde urethrography is the appropriate choice because the patient has blood in the external urethral meatus, indicating a possible urethral injury. 2. This imaging technique involves injecting contrast material into the urethra to visualize any urethral abnormalities or injuries. 3. It is a non-invasive and effective method to assess the extent of urethral trauma in cases like this. 4. Cystoscopy (Choice A) is not the initial study of choice in this scenario as it primarily visualizes the bladder and may not provide adequate information about urethral injuries. 5. Cystography (Choice B) and IV pyelography (Choice C) are not appropriate in this case as they focus on assessing the bladder and kidneys, respectively, which are not the primary concerns based on the patient's

Correct Answer: C

Rationale: The correct answer is C: Primary nursing. In primary nursing, the registered nurse takes on the responsibility for the majority of daily care for specific residents. This model promotes continuity of care and allows the nurse to develop a deeper understanding of the residents' needs. Facility nursing (A) refers to care provided by nurses within a healthcare facility without specifying a particular nurse's role. Team nursing (B) involves a team of healthcare providers working together to deliver care, without one nurse taking primary responsibility. Functional nursing (D) assigns specific tasks to different nursing personnel rather than focusing on individualized care by a single nurse.

Correct Answer: C

Rationale: The correct answer is C: Return charts to their proper place after use. This is the best way for a nursing assistant to keep residents' health information confidential because it ensures that sensitive information is stored securely and not left out in the open where unauthorized individuals can access it. By returning charts to their proper place, the nursing assistant is following proper protocol for maintaining confidentiality and upholding the residents' right to privacy. Choice A is incorrect because discussing a resident's information away from the facility does not guarantee confidentiality and can still risk unauthorized disclosure. Choice B is incorrect as bringing family and friends to the facility can compromise residents' privacy and confidentiality. Choice D is incorrect as posting updates about residents on social media violates their right to privacy and confidentiality.

Correct Answer: B

Rationale: The correct answer is B: Chest pain. Chest pain could be a sign of a serious medical condition like a heart attack, which requires immediate attention. Reporting chest pain to the nurse promptly can lead to timely intervention and potentially save a resident's life. Choices A, C, and D are incorrect as they do not pose immediate life-threatening risks and can be addressed at a later time. Family visiting, watching too much TV, and acting lonely are important aspects of resident care but do not require urgent reporting compared to a potentially critical symptom like chest pain.
