Critical Care Nursing Questions Questions
Question 1 of 9
To maintain proper cuff pressure of an endotracheal tube (ET) when the patient is on mechanical ventilation, the nurse should:
Correct Answer: D
Rationale: The correct answer is D because inflating the cuff until a slight leak is heard only at peak inflation ensures it is adequately sealed but not overinflated, preventing complications like tracheal injury or pressure necrosis. Choice A lacks specificity and can lead to overinflation. Choice B may result in overinflation as the firmness of the balloon is subjective. Choice C relies on a specific pressure reading, which may vary based on factors like tube size and patient anatomy, potentially leading to under- or overinflation.
Question 2 of 9
The urgent care center protocol for tick bites includes the following actions. Which action will the nurse take first when caring for a patient with a tick bite?
Correct Answer: A
Rationale: The correct answer is A: Use tweezers to remove any remaining ticks. The first step is to remove the tick to prevent further transmission of any potential pathogens. This is crucial in preventing tick-borne illnesses. Checking vital signs (B) can be done after the tick is removed. Administering doxycycline (C) should be based on guidelines and individual factors. Obtaining information about recent outdoor activities (D) is important but not the immediate priority.
Question 3 of 9
Which of the following are components of the Institute for Healthcare Improvement’s (IHI’s) ventilator bundle? (Select all that apply.)
Correct Answer: A
Rationale: The correct answer is A because interrupting sedation daily to assess readiness to extubate is a key component of IHI's ventilator bundle to prevent ventilator-associated pneumonia. This practice helps prevent over-sedation, reduce the duration of mechanical ventilation, and decrease the risk of complications. The other choices, B, C, and D, are incorrect as they are not specific components of the IHI's ventilator bundle. Maintaining head of bed elevation, providing deep vein thrombosis prophylaxis, and prophylaxis for peptic ulcer disease are important aspects of critical care but are not directly related to the ventilator bundle protocol outlined by IHI.
Question 4 of 9
A nurse is on a committee that is trying to reduce the occurrence of hospital-acquired infections in the ICU. Her role is to conduct research to find which interventions have been shown to be most effective in reducing these infections. She consults many different sources and finds conflicting information. Which of the following sources should she consider the most authoritative?
Correct Answer: B
Rationale: The correct answer is B: A meta-analysis of randomized controlled trials in the American Journal of Nursing. 1. Meta-analyses provide a comprehensive overview of multiple studies, increasing the reliability of the findings. 2. Randomized controlled trials are considered the gold standard in research design for assessing intervention effectiveness. 3. The American Journal of Nursing is a reputable source in the field of nursing, ensuring the credibility of the study. 4. By synthesizing data from various trials, the meta-analysis can offer a more robust and generalizable conclusion compared to a single trial or qualitative studies. Incorrect choices: A: AACN expert panel report - Expert opinions may vary and lack the empirical evidence provided by research studies. C: A systematic review of qualitative studies in the Journal of Advanced Nursing - Qualitative studies may provide valuable insights but may not offer concrete evidence on intervention effectiveness like quantitative studies. D: A single randomized controlled trial in the American Journal of Critical Care - Single trials may not capture the full picture and
Question 5 of 9
The nurse returns from the cardiac catheterization laboratory with a patient following insertion of a pulmonary artery catheter and assists in transferring th e patient from the stretcher to the bed. Prior to obtaining a cardiac output, which action is m ost important for the nurse to complete?
Correct Answer: B
Rationale: The correct answer is B: Zero reference the transducer system at the phlebostatic axis. This is the most important action before obtaining a cardiac output because zero referencing ensures accurate pressure readings. The phlebostatic axis is the level of the atria when the patient is supine, and zeroing at this point minimizes errors in pressure measurements. Choice A is incorrect because documenting a pulmonary artery catheter occlusion pressure is not the priority at this stage. Choice C is incorrect as inflating the balloon with air should be done after zero referencing. Choice D is incorrect as injecting normal saline into the port is not necessary before zero referencing.
Question 6 of 9
A patient is admitted to the emergency department (ED) after falling through the ice while ice skating. Which assessment will the nurse obtain first?
Correct Answer: C
Rationale: The correct answer is C: Body temperature. In a patient who has fallen through the ice, hypothermia is a major concern due to exposure to cold water. Assessing body temperature first is crucial to determine the severity of hypothermia and guide immediate interventions. Heart rate, breath sounds, and level of consciousness can be affected by hypothermia but are secondary assessments. Assessing body temperature is the priority to address the most life-threatening issue first.
Question 7 of 9
Which intervention is appropriate to assist the patient to co pe with admission to the critical care unit?
Correct Answer: B
Rationale: The correct answer is B: Explaining all procedures in easy-to-understand terms. This intervention is appropriate as it helps reduce the patient's anxiety by providing clear information about what to expect during their stay in the critical care unit. This promotes a sense of control and understanding, which can positively impact the patient's coping mechanisms. A: Allowing unrestricted visiting by several family members at one time may overwhelm the patient and interfere with their rest and recovery. C: Providing back massage and mouth care may be beneficial but may not directly address the patient's need for information and understanding. D: Turning down the alarm volume on the cardiac monitor may provide a more comfortable environment but does not address the patient's emotional and psychological needs related to coping with admission to the critical care unit.
Question 8 of 9
The nurse is caring for an elderly patient who was admitted with renal insufficiency. An expected laboratory finding for this patient may be
Correct Answer: B
Rationale: The correct answer is B: a normal serum creatinine level. In renal insufficiency, the kidneys are not able to filter waste products effectively, leading to an increase in serum creatinine levels. This is a common indicator of renal dysfunction. A: An increased GFR would not be expected in renal insufficiency, as it signifies improved kidney function. C: Increased ability to excrete drugs is not a typical finding in renal insufficiency, as impaired kidney function can lead to drug accumulation. D: Hypokalemia is not directly related to renal insufficiency. It is more commonly associated with factors like diuretic use or gastrointestinal losses.
Question 9 of 9
The nurse is assessing pain levels in a critically ill patient . The nurse recognizes that which patient action as indicatin g the greatest level of pain?
Correct Answer: C
Rationale: Correct Answer: C (Grimacing) Rationale: 1. Grimacing is a universal nonverbal sign of pain. 2. It involves facial muscles, indicating a high level of discomfort. 3. Brow lowering and eyelid closing are subtle signs, less indicative of severe pain. 4. Staring may signify concentration, not necessarily pain. Summary: Grimacing is the correct choice as it directly correlates with pain intensity, unlike the other options which are less specific or relevant indicators of severe pain.
