How should a healthcare professional care for a patient with a central venous catheter?

Correct Answer: A

Rationale: Corrected Rationale: Regular monitoring for infection and dressing changes are essential aspects of caring for a patient with a central venous catheter. Infections are a significant risk with these catheters, so vigilant monitoring and timely dressing changes help prevent complications. Choice B is important too, but ensuring catheter patency and flushing are more focused on maintaining the functionality of the catheter rather than infection prevention. Choice C is also important for patient education, but the immediate concern for a healthcare professional is monitoring and preventing infections related to the catheter. Choice D is not directly related to the care of a central venous catheter.

Correct Answer: A

Rationale: Correct answer: Monitoring airway patency and providing humidified oxygen is crucial in managing a patient with a tracheostomy to ensure proper breathing and oxygenation. Ensuring the airway is clear and providing oxygen support are immediate priorities. Providing education on tracheostomy care (Choice B) is important for long-term management but not the immediate priority. Suctioning airway secretions and changing tracheostomy ties (Choice C) are tasks that may be necessary but do not address the primary concern of maintaining airway patency. Providing a high-protein diet and ensuring fluid restriction (Choice D) are unrelated to the immediate management of a tracheostomy.

Correct Answer: A

Rationale: The correct answer is A: Sepsis and respiratory failure. Untreated pneumonia can lead to severe complications such as sepsis, which is a life-threatening response to infection, and respiratory failure, where the lungs can no longer provide enough oxygen to the body. Heart failure and kidney failure (choice B) are not direct complications of untreated pneumonia. Pulmonary embolism and electrolyte imbalance (choice C) are also not commonly associated with untreated pneumonia. Liver failure and electrolyte imbalance (choice D) are not typical complications of pneumonia.

Correct Answer: A

Rationale: Hypoglycemia typically presents with sweating and trembling, while hyperglycemia is characterized by frequent urination and thirst. Therefore, the correct key differences between hypoglycemia and hyperglycemia are that hypoglycemia includes symptoms like sweating and trembling, while hyperglycemia involves symptoms such as frequent urination and thirst. Choices B, C, and D are incorrect because they do not accurately represent the characteristic symptoms of hypoglycemia and hyperglycemia, as stated in the question.

Correct Answer: C

Rationale: The correct answer is C: Previous violent behavior. This is considered the best predictor of future violent actions as individuals who have a history of violent behavior are more likely to engage in violent acts again. Option A, experiencing delusions, although it can impact behavior, is not as strong of a predictor as past violent behavior. Option B, male gender, is a demographic factor but not as specific or predictive as a history of violence. Option D, a history of being in prison, may indicate past behavior but is not directly linked to future violent actions as a known history of violence.
