Critical Care Nursing NCLEX Questions Questions
Question 1 of 9
The nurse is caring for a patient who is orally intubated and on a mechanical ventilator. The nurse believes that the patient is experiencing excess anxiety. For this patient, what behavior best indicates anxiety?
Correct Answer: A
Rationale: The correct answer is A: Restlessness. Restlessness is a common behavioral indicator of anxiety in patients. In this scenario, a patient who is orally intubated and on a ventilator may not be able to verbally express anxiety, making restlessness a more prominent sign. Verbalization may not be possible due to intubation. While increased respiratory rate can be a symptom of anxiety, it is also a common physiological response in patients on mechanical ventilation. A Glasgow Coma Scale score of 3 indicates severe impairment of consciousness, not specifically anxiety.
Question 2 of 9
A nurse is the only one in the ICU who has not achieved certification in critical care nursing. She often will ask her fellow nurses what to do in caring for a patient because she doubts the accuracy of her knowledge and her intuition. She loves her work but wishes she could do it with a greater level of competence. What is the most important effect that obtaining certification would likely have on the nurses practice?
Correct Answer: D
Rationale: The correct answer is D: Increased confidence in making decisions. Obtaining certification in critical care nursing would likely enhance the nurse's knowledge and skills, leading to increased confidence in making clinical decisions. This confidence would stem from the rigorous training and education required to achieve certification, as well as the validation of her expertise in critical care nursing. With increased confidence, the nurse would be more self-assured in her abilities, leading to improved patient care outcomes. Choice A: Recognition by peers is not the most important effect because while recognition is a positive outcome, it may not directly impact the nurse's ability to provide better patient care. Choice B: Increase in salary and rank is not the most important effect because while financial benefits are important, the primary focus of obtaining certification should be on improving competence and patient care. Choice C: More flexibility in seeking employment is not the most important effect because while certification may open up more job opportunities, the main benefit should be on enhancing the nurse's skills and confidence in providing quality
Question 3 of 9
The nurse is caring for a patient in acute respiratory failure and understands that the patient should be positioned (Select all that apply.)
Correct Answer: A
Rationale: The correct answer is A: high Fowler's position. This position promotes optimal lung expansion by allowing the chest to expand fully, improving oxygenation. It also helps reduce the work of breathing. Side lying with the head of the bed elevated (B) may not provide the same level of lung expansion. Sitting in a chair (C) may not be suitable for a patient in acute respiratory failure as it may not provide adequate support for breathing. Supine with the bed flat (D) can worsen respiratory distress by limiting lung expansion.
Question 4 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 5 of 9
A client with cancer has a history of alcohol abuse and is taking acetaminophen (Tylenol) for pain. Which organ function is most important for the nurse to monitor?
Correct Answer: B
Rationale: The correct answer is B: Liver. The nurse should monitor liver function in this client because acetaminophen is primarily metabolized in the liver. Alcohol abuse can also contribute to liver damage, increasing the risk of liver toxicity from acetaminophen. Monitoring liver function tests like AST, ALT, and bilirubin levels can help detect any liver damage early. Choice A, cardiorespiratory, is not directly related to acetaminophen or alcohol abuse in this scenario. Choice C, sensory, is not relevant to monitoring organ function in this context. Choice D, kidney, is not the primary concern because acetaminophen is mainly metabolized in the liver, and kidney function is not typically affected by acetaminophen use.
Question 6 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 7 of 9
The nurse is caring for a patient who has a temporary percutaneous dialysis catheter in place. In caring for this patient, the nurse should
Correct Answer: C
Rationale: The correct answer is C because assessing the catheter site for redness and/or swelling is crucial for early detection of infection. Redness and swelling are common signs of infection at the catheter site, which requires prompt intervention. Applying a sterile gauze dressing (choice A) is not necessary for a temporary percutaneous dialysis catheter. Replacing the transparent dressing every 10 days (choice B) is not recommended as it can increase the risk of infection. Using the catheter for drawing blood samples (choice D) is not appropriate as it can introduce contaminants and increase the risk of infection. Regular assessment of the catheter site is essential for early detection and prevention of complications.
Question 8 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 9 of 9
During a client assessment, the client says, 'I can't walk very well.' Which action should the nurse implement first?
Correct Answer: D
Rationale: The correct answer is D: Identify the problem. This is the first action the nurse should take in the nursing process as it helps in understanding the client's issue. By identifying the problem, the nurse can gather more information through further assessment to determine the underlying cause of the client's difficulty in walking. This step is crucial for developing an effective care plan and interventions. A: Predict the likelihood of the outcome - This choice is not appropriate as predicting the outcome should come after identifying the problem and implementing interventions. B: Consider alternatives - While considering alternatives is important in the decision-making process, it is not the immediate action needed in this scenario. C: Choose the most successful approach - This choice is premature as the nurse needs to first identify the problem before determining the most successful approach.
