Critical Care Nursing NCLEX Questions Questions
Question 1 of 9
Identify which substances in the glomerular filtrate would indicate a problem with renal function. (Select all that apply.)
Correct Answer: A
Rationale: The presence of protein in the glomerular filtrate indicates a problem with renal function because in healthy kidneys, proteins are retained in the blood and not filtered into the urine. If protein is found in the filtrate, it suggests damage to the glomerular filtration barrier. Sodium, creatinine, and red blood cells are normally present in the filtrate and are not indicative of renal dysfunction. Sodium is freely filtered and reabsorbed, creatinine is a waste product of muscle metabolism excreted by the kidneys, and a small number of red blood cells may be filtered due to their small size. Therefore, protein in the glomerular filtrate is the most specific indicator of renal dysfunction.
Question 2 of 9
A nurse in a burn unit observes that a patient is tensed up and frowning but silent. The nurse asks the patient, Can you tell me what you are thinking now? The patient responds, I cant take this pain any more! I feel like Im about to die. What would be the best response for the nurse to give to the patient, considering that the patient is already receiving the maximum amount pain medication that is safe?
Correct Answer: C
Rationale: The correct response is C: Your pain medication is already at the highest possible dose. This response acknowledges the patient's pain and reassures them that they are already receiving the maximum safe amount of pain medication. By stating this, the nurse is validating the patient's experience and showing empathy. It is important for the nurse to communicate clearly about the medication to manage the patient's expectations. Choice A is incorrect as it dismisses the patient's pain and can come across as insensitive. Choice B may be well-intentioned but does not address the immediate concern of the patient's pain. Choice D is irrelevant to the patient's statement about pain and does not offer any immediate support or reassurance regarding the pain management.
Question 3 of 9
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 4 of 9
In assessing a patient, the nurse understands that what sym ptomology is an early sign of hypoxemia?
Correct Answer: D
Rationale: Step 1: Restlessness is an early sign of hypoxemia due to the body's response to low oxygen levels. Step 2: Restlessness occurs as the body tries to increase oxygen intake. Step 3: Other choices are incorrect because clubbing and cyanosis are late signs, while hypotension is not a specific early sign of hypoxemia.
Question 5 of 9
When evaluating a patient with a central venous catheter, the nurse observes that the insertion site is red and tender to touch and the patient’s temperature is 101.8°F. What should the nurse plan to do next?
Correct Answer: B
Rationale: The correct answer is B: Discontinue the catheter and culture the tip. The patient's symptoms indicate a possible catheter-related infection. Discontinuing the catheter will prevent further infection spread. Culturing the tip will identify the specific pathogen causing the infection, guiding appropriate antibiotic therapy. Choice A is incorrect because giving analgesics alone will not address the underlying infection. Choice C is incorrect as changing the flush system is not a priority when infection is suspected. Choice D is incorrect as checking the site more frequently does not address the need for immediate action to address the infection.
Question 6 of 9
A PaCO 2 of 48 mm Hg is associated with what outcome?
Correct Answer: B
Rationale: The correct answer is B: Hypoventilation. A PaCO2 of 48 mm Hg indicates an elevated level of carbon dioxide in the blood, which is typically seen in hypoventilation where the lungs are not effectively removing CO2. Hypoventilation leads to respiratory acidosis. Option A is incorrect because hyperventilation would decrease PaCO2 levels. Option C is incorrect as it does not directly relate to PaCO2 levels. Option D is incorrect as increased excretion of HCO3- would not directly affect PaCO2 levels.
Question 7 of 9
The assessment of pain and anxiety is a continuous proces s. When critically ill patients exhibit signs of anxiety, what is the nurse’s first priority?
Correct Answer: C
Rationale: The correct answer is C: To identify and treat the underlying cause. The first priority of the nurse when critically ill patients exhibit signs of anxiety is to determine the root cause of the anxiety. By identifying and addressing the underlying cause, the nurse can effectively manage the patient's anxiety and prevent further complications. Administering medications without understanding the cause can mask the symptoms and lead to ineffective treatment. Reassessing the patient hourly may not address the root cause and could delay appropriate intervention. Pain medication may not be necessary if the anxiety is not related to pain. Treating the underlying cause ensures holistic and effective care for the patient.
Question 8 of 9
A client with asthma receives a prescription for high blood pressure during a clinic visit. Which prescription should the nurse anticipate the client to receive that is least likely to exacerbate asthma?
Correct Answer: D
Rationale: The correct answer is D, Metoprolol tartrate (Lopressor). Metoprolol is a cardioselective beta-blocker that primarily targets beta-1 receptors in the heart, making it less likely to exacerbate asthma compared to non-selective beta-blockers like Propranolol (choice B) and Pindolol (choice C). Carteolol (choice A) is also a non-selective beta-blocker and can potentially worsen asthma symptoms. Metoprolol's selectivity for beta-1 receptors minimizes bronchoconstriction, making it the safest choice for a client with asthma and high blood pressure.
Question 9 of 9
The critical care nurse is responsible for monitoring the patient receiving continuous renal replacement therapy (CRRT). In doing so, the nurse should
Correct Answer: B
Rationale: The correct answer is B because assessing the hemofilter every 6 hours for clotting is essential in ensuring the effectiveness of CRRT. Clotting can obstruct blood flow, leading to treatment inefficiency and potential harm to the patient. This step helps the nurse to promptly address any clotting issues and prevent complications. A: Assessing that the blood tubing is warm to the touch is not a standard practice for monitoring CRRT and does not provide relevant information about the treatment's effectiveness. C: Covering the dialysis lines to protect them from light is not a priority in monitoring CRRT. Light exposure is not a common concern in this context. D: Using clean technique during vascular access dressing changes is important for infection prevention but is not directly related to monitoring the effectiveness of CRRT.
