Critical Care Nursing NCLEX Questions Questions
Question 1 of 5
The charge nurse has a Vigileo pulse contour cardiac output monitoring system available for use in the surgical intensive care unit. For which patient isa buisrbe.c oomf /ttehsits device most appropriate?
Correct Answer: B
Rationale: The correct answer is B because a mechanically ventilated patient with cardiogenic shock being treated with an intra-aortic balloon pump would benefit most from having a Vigileo pulse contour cardiac output monitoring system. This device provides continuous cardiac output monitoring and can help guide hemodynamic management in critically ill patients, especially those with hemodynamic instability like cardiogenic shock. It allows for real-time adjustments of fluid and vasoactive medications to optimize cardiac output and tissue perfusion. Choice A is incorrect because a patient with a history of aortic insufficiency and postoperative myocardial infarction may not require continuous cardiac output monitoring like the patient in choice B. Choice C is incorrect as the patient with atrial fibrillation and paroxysmal supraventricular tachycardia does not necessarily need cardiac output monitoring. Choice D is also incorrect as a mechanically ventilated patient following repair of an acute bowel obstruction may not require continuous cardiac output monitoring unless there are specific complications.
Question 2 of 5
Which nursing actions are most important for a patient witahb irab .croigmh/tte srta dial arterial line? (Select all that apply.)
Correct Answer: A
Rationale: Step 1: Checking circulation to the right hand is crucial for assessing perfusion and detecting potential complications. Step 2: Arterial line placement can compromise blood flow, leading to ischemia if circulation is impaired. Step 3: Monitoring circulation every 2 hours allows for early detection of issues and prompt intervention. Step 4: This action ensures patient safety and prevents complications. Summary: - Choice B is incorrect as pressurized flush solution can increase the risk of complications. - Choice C is incorrect as monitoring the waveform is important but not the most critical action. - Choice D is incorrect as limb restraints can impede circulation and are unnecessary in this scenario.
Question 3 of 5
A normal glomerular filtration rate is
Correct Answer: B
Rationale: The correct answer is B (80 to 125 mL/min) because this range reflects the normal glomerular filtration rate (GFR) in adults. GFR measures the rate at which blood is filtered by the kidneys, typically around 125 mL/min. A GFR below 60 mL/min indicates kidney dysfunction, making option A incorrect. Option C (125 to 180 mL/min) is above the normal range. Option D (more than 189 mL/min) is too high and could indicate hyperfiltration, common in conditions like diabetes. Therefore, choice B is the most appropriate within the normal GFR range.
Question 4 of 5
The nurse is caring for a patient who has undergone major abdominal surgery. The nurse notices that the patient’s urine output has been less than 20 mL/hour for the past 2 hours. The patient’s blood pressure is 100/60 mm Hg, and the pulse is 110 beats/min. Previously, the pulse was 90 beats/min with a blood pressure of 120/80 mm Hg. The nurse should
Correct Answer: A
Rationale: The correct answer is A: contact the provider and expect a prescription for a normal saline bolus. The patient is showing signs of hypovolemia with decreased urine output, low blood pressure, and elevated heart rate. This indicates inadequate perfusion and potential hypovolemic shock. Administering a normal saline bolus will help restore intravascular volume and improve perfusion. Waiting for the provider to make rounds (option B) could delay necessary intervention. Continuing to evaluate urine output for 2 more hours (option C) is not appropriate given the patient's current condition. Ignoring the urine output (option D) is dangerous as it could lead to further complications.
Question 5 of 5
The patient has elevated blood urea nitrogen (BUN) and serum creatinine levels with a normal BUN/creatinine ratio. These levels most likely indicate
Correct Answer: B
Rationale: The elevated BUN and creatinine levels with a normal BUN/creatinine ratio indicate impaired kidney function. This pattern is commonly seen in acute kidney injury, such as acute tubular necrosis (ATN). In ATN, there is damage to the renal tubules leading to decreased excretion of waste products, resulting in elevated BUN and creatinine levels. The normal BUN/creatinine ratio suggests that the impairment is due to renal tubular dysfunction rather than prerenal causes like hypovolemia or postrenal causes like urinary obstruction. Increased nitrogen intake would not produce this specific pattern of results. Fluid resuscitation would likely result in dilution of BUN and creatinine levels, leading to lower values.
