Question 1 of 5
What is the primary purpose of administering IV fluids to a patient in septic shock?
Correct Answer: D
Rationale: The primary purpose of administering IV fluids to a patient in septic shock is to maintain adequate tissue perfusion. In septic shock, there is a significant drop in blood pressure and systemic vascular resistance leading to poor tissue perfusion. IV fluids help to restore intravascular volume, improve perfusion to vital organs, and prevent organ failure. Choice A ('To reduce blood pressure') is incorrect because IV fluids in septic shock aim to restore tissue perfusion rather than lower blood pressure. Choice B ('To increase cardiac output') is incorrect as the primary goal is to improve tissue perfusion, not specifically increase cardiac output. Choice C ('To stabilize blood glucose levels') is unrelated to the primary purpose of administering IV fluids in septic shock, which is to address the compromised tissue perfusion.
Question 2 of 5
What is the most common side effect of diuretics such as furosemide (Lasix)?
Correct Answer: A
Rationale: The correct answer is 'Hypokalemia.' Diuretics like furosemide increase the excretion of potassium, leading to hypokalemia as a common side effect. Hyperkalemia (choice B) is the opposite condition characterized by high potassium levels, which is not typically associated with furosemide use. Hypernatremia (choice C) is increased sodium levels, while hyponatremia (choice D) is decreased sodium levels, neither of which are the most common side effects of furosemide. Therefore, choice A is the best answer.
Question 3 of 5
What is the most important nursing intervention for a patient with increased intracranial pressure (ICP)?
Correct Answer: A
Rationale: Elevating the head of the bed to 30 degrees is crucial for a patient with increased intracranial pressure (ICP) because it helps promote venous drainage from the brain, thereby reducing ICP. Keeping the head of the bed elevated helps facilitate cerebral perfusion and can prevent a further increase in ICP. Administering diuretics (Choice B) may be considered in some cases to reduce fluid volume, but it is not the most critical intervention for immediate ICP management. Administering corticosteroids (Choice C) is not typically indicated for managing increased ICP unless there is a specific underlying condition requiring their use. Keeping the patient in a supine position (Choice D) can actually worsen ICP by impeding venous outflow from the brain, making it an incorrect choice for this scenario.
Question 4 of 5
Which of the following interventions is most appropriate for a patient with acute pancreatitis?
Correct Answer: B
Rationale: The most appropriate intervention for a patient with acute pancreatitis is administering IV fluids. IV fluid administration is crucial in managing acute pancreatitis as it helps maintain hydration, correct electrolyte imbalances, and prevent shock. Administering oral fluids (Choice A) may not be sufficient to address the fluid loss and maintain hydration in these patients. While analgesics (Choice C) are important for pain management in pancreatitis, addressing hydration and shock prevention takes precedence. Encouraging the patient to ambulate (Choice D) may be beneficial in some cases for preventing complications like deep vein thrombosis, but it is not the primary intervention needed in the acute phase of pancreatitis.
Question 5 of 5
Which of the following is a priority intervention for a patient with suspected sepsis?
Correct Answer: D
Rationale: Monitoring blood cultures is a crucial intervention in suspected sepsis because it helps identify the causative organism, which is essential for guiding appropriate antibiotic therapy. Administering antibiotics (Choice A) is important but should be guided by blood culture results. Administering IV fluids (Choice B) is also essential to support hemodynamic stability in sepsis. Administering antipyretics (Choice C) may help reduce fever but is not a priority compared to identifying the causative organism through blood cultures.
