Correct Answer: B

Rationale: The correct answer is B: 'Murmur.' A murmur is a swishing sound heard during auscultation, typically caused by turbulent blood flow through the heart or valves. Choices C and D, 'S3 sound' and 'S4 sound,' refer to specific heart sounds associated with different cardiac conditions, not the general description of a swishing sound. Choice A, 'Heart murmur,' is redundant as 'murmur' alone is sufficient to describe the swishing sound heard.

Correct Answer: B

Rationale: The correct answer is B: Prepare the client for dialysis. Clients with acute kidney injury and elevated creatinine may require dialysis to support kidney function and remove waste products from the blood. Preparing for dialysis ensures timely intervention in preventing further complications. Administering diuretics (Choice A) may worsen the client's condition by further compromising kidney function. Restricting fluid intake (Choice C) may be necessary in some cases, but it is not the priority over preparing for dialysis. Notifying the healthcare provider (Choice D) is important, but the immediate priority is to prepare for dialysis to address the acute kidney injury and elevated creatinine level.

Correct Answer: A

Rationale: Correct Answer: Monitoring respiratory status and oxygenation is crucial in clients with lung cancer, as metastasis to the lungs or pleural effusion can compromise breathing. This assessment helps in early identification of respiratory distress and the need for interventions to maintain adequate oxygenation. Choice B is important but not the priority in this situation. Evaluating mental status and cognition should follow after ensuring the client's physiological needs are met. Choice C, checking pain level and providing comfort, is essential but secondary to assessing respiratory status. Choice D, assessing nutritional status and appetite, is also important but not the priority when the client's breathing is at risk.

Correct Answer: D

Rationale: In this scenario, the patient's periorbital bruising and bloody drainage from both ears suggest a severe head injury. Projectile vomiting is a red flag symptom that may indicate increased intracranial pressure, which requires immediate attention to prevent further neurological deterioration. Rebound abdominal tenderness (choice A) typically indicates peritonitis and is not directly related to the primary head injury. Diminished breath sounds bilaterally (choice B) suggest a pneumothorax or hemothorax, which are important but not as immediately life-threatening in this context. Rib pain with deep inspiration (choice C) is concerning for rib fractures or pulmonary contusion, which are also important but do not take precedence over addressing the potential increased intracranial pressure.

Correct Answer: B

Rationale: Muscle cramps and tingling in clients with chronic renal failure are often associated with hypocalcemia. Monitoring calcium levels is crucial to identify imbalances and manage symptoms appropriately. Sodium, phosphate, and potassium levels are important in renal failure but are not directly related to the symptoms of muscle cramps and tingling reported by the client.
