A nurse is caring for a client who is receiving total parenteral nutrition (TPN). Which of the following actions should the nurse take to prevent infection?

Correct Answer: B

Rationale: The correct answer is B. Changing the TPN tubing every 24 hours is crucial in preventing infection by reducing the risk of bacterial contamination. Monitoring electrolyte levels (choice A) is essential but not directly related to preventing TPN-related infections. Monitoring blood glucose levels (choice C) is important for clients receiving TPN, but it is more related to glycemic control than infection prevention. Administering insulin as prescribed (choice D) is necessary for clients with diabetes but is not directly linked to preventing TPN-related infections.

Correct Answer: A

Rationale: The correct answer is A: 'Monitor for changes in the level of consciousness.' Key signs of increased intracranial pressure (ICP) include changes in the level of consciousness and pupil dilation. Assessing for bradycardia and monitoring for vomiting are not typically considered primary signs of increased ICP. While bradycardia and vomiting can occur with increased ICP, they are not as specific or sensitive as changes in consciousness and pupil dilation.

Correct Answer: D

Rationale: In cases of anaphylaxis, all of the listed interventions are crucial for effective management. Administering epinephrine is the primary treatment to reverse the allergic reaction rapidly. Providing oxygen ensures adequate oxygenation to vital organs, and monitoring the airway is essential to prevent obstruction and maintain a clear air passage. Therefore, all three interventions are necessary in managing anaphylaxis. Choices A, B, and C are not individually sufficient to address all aspects of anaphylaxis, making the comprehensive approach of 'All of the above' the correct answer.

Correct Answer: D

Rationale: When managing a patient with diabetic ketoacidosis (DKA), it is crucial to administer insulin to lower blood sugar levels, administer IV fluids to correct dehydration and electrolyte imbalances, and monitor blood glucose levels regularly to ensure they are within the target range. Therefore, all of the above options are essential components of the comprehensive treatment plan for DKA. Administering insulin alone may lower blood sugar levels but will not address the fluid and electrolyte imbalances seen in DKA. Similarly, administering IV fluids alone may help with dehydration but will not address the high blood sugar levels or the need for insulin. Monitoring blood glucose alone is not sufficient to treat DKA; it must be accompanied by appropriate interventions to address the underlying causes and complications of the condition.

Correct Answer: A

Rationale: Shortness of breath is a primary symptom of left-sided heart failure. In this condition, the heart's inability to pump effectively leads to fluid backing up into the lungs, causing difficulty breathing. Edema (swelling), rapid heartbeat, and confusion are more commonly associated with other conditions or right-sided heart failure. Edema is often seen in right-sided heart failure due to fluid accumulation in the body, rapid heartbeat can be a general sign of heart issues, and confusion is more related to decreased brain perfusion in severe heart failure cases.
