Critical Care Nursing Questions and Answers PDF Questions
Question 1 of 9
A 45-year-old postsurgical patient is on a ventilator in the critical care unit has been tolerating the ventilator well and has not required any sedation. The apbairtbi.ecnomt /bteesct omes tachycardic and hypertensive with a respiratory rate that has increased to 28 breaths/min. The ventilator is set on synchronized intermittent mandatory ventilation (SIMV ) at a rate of 10 breaths/min. The patient has been suctioned recently via existing endotracheal tube until airway is clear. When the patient responds appropriately to the nurse’s command s, what should be the nurse’s priority intervention?
Correct Answer: A
Rationale: The correct answer is A: Assessing the patient's level of pain. In this situation, the patient's tachycardia, hypertension, and increased respiratory rate could be indicative of pain. By assessing the patient's pain level, the nurse can address any discomfort the patient may be experiencing, which could be contributing to these physiological responses. Summary of other choices: B: Decreasing the SIMV rate on the ventilator - This is not the priority intervention as the patient's symptoms are more likely related to pain rather than the ventilator settings. C: Providing sedation as ordered - Sedation is not the priority in this case as the patient has been tolerating the ventilator well without requiring sedation. D: Suctioning the patient again - Since the airway has been recently cleared, suctioning again is not necessary at this point and would not address the underlying cause of the patient's symptoms.
Question 2 of 9
An intra-aortic balloon pump (IABP) is being used for a patient who is in cardiogenic shock. Which assessment data indicate to the nurse that the goals of treatment with the IABP are being met?
Correct Answer: C
Rationale: The correct answer is C: Cardiac output (CO) of 5 L/min. In cardiogenic shock, the primary goal of using an IABP is to improve cardiac output to ensure adequate perfusion to vital organs. A cardiac output of 5 L/min indicates adequate blood flow and perfusion. Choice A is incorrect as urine output is not a direct indicator of cardiac function. Choice B is incorrect as a heart rate of 110 beats/minute alone does not provide information on the effectiveness of the IABP in improving cardiac output. Choice D is incorrect as stroke volume alone does not provide a comprehensive assessment of overall cardiac function.
Question 3 of 9
A patient is having difficulty weaning from mechanical ve ntilation. The nurse assesses the patient and notes what potential cause of this difficult weaning?
Correct Answer: B
Rationale: The correct answer is B: Hemoglobin of 8 g/dL. Low hemoglobin levels can lead to inadequate oxygen delivery to tissues, causing respiratory distress and difficulty weaning from mechanical ventilation. This is due to reduced oxygen-carrying capacity leading to increased work of breathing. A: Cardiac output of 6 L/min is within normal range and not directly related to difficulty weaning from mechanical ventilation. C: Negative sputum culture and sensitivity indicate absence of respiratory infection but not a direct cause of difficulty weaning. D: White blood cell count of 8000 is within normal range and not a direct cause of difficulty weaning.
Question 4 of 9
The patient is in the critical care unit and will receive dialysis this morning. The nurse will (Select all that apply.)
Correct Answer: A
Rationale: The correct answer is A because evaluating morning lab results is crucial to monitor the patient's condition before dialysis. Abnormal results may impact the dialysis treatment plan. Option B is incorrect as administering antihypertensive medications is not directly related to dialysis. Option C is incorrect as assessing the dialysis access site is the responsibility of the dialysis team. Option D is incorrect as weighing the patient is not typically done immediately before dialysis.
Question 5 of 9
When monitoring the effectiveness of treatment for a patient with a large anterior wall myocardial infarction, the most important information for the nurse to obtain is:
Correct Answer: D
Rationale: The correct answer is D: Pulmonary artery wedge pressure (PAWP). This is crucial in monitoring a patient with a large anterior wall myocardial infarction as it provides information on left ventricular function and fluid status. A high PAWP may indicate left ventricular failure or fluid overload, requiring immediate intervention. A: Central venous pressure (CVP) is not as specific for assessing left ventricular function and may not provide accurate information in this scenario. B: Systemic vascular resistance (SVR) is important in assessing systemic blood flow, but it may not directly indicate left ventricular function in this case. C: Pulmonary vascular resistance (PVR) is more relevant in conditions affecting the pulmonary circulation and may not be as immediately informative in assessing left ventricular function in this context.
Question 6 of 9
The nurse is caring for a patient who has sustained blunt trauma to the left flank area, and is evaluating the patient’s urinalysis results. The nurse should become concerned when
Correct Answer: D
Rationale: The correct answer is D because the presence of red blood cells and albumin in the urine indicates possible kidney damage from the blunt trauma. This is concerning as it may suggest renal injury or dysfunction. A: Creatinine levels in the urine being similar to blood levels is normal as creatinine is filtered by the kidneys. B: Sodium and chloride being present in the urine is expected as they are components of urine. C: Urine uric acid levels matching serum levels is common as uric acid is excreted by the kidneys. In summary, the presence of red blood cells and albumin in the urine is abnormal and indicates potential kidney damage, making it the correct answer.
Question 7 of 9
What is the treatment for an acute exacerbation of asthma?
Correct Answer: B
Rationale: The correct answer is B: Inhaled bronchodilators and intravenous corticosteroids. Bronchodilators help to quickly open up the airways during an asthma exacerbation, providing immediate relief. Intravenous corticosteroids help reduce airway inflammation and prevent further worsening of symptoms. Corticosteroids by mouth (Choice A) are not as effective as intravenous administration during an acute exacerbation. Prone positioning or continuous lateral rotation (Choice C) is not a recommended treatment for asthma exacerbation. Sedation and inhaled bronchodilators (Choice D) are not appropriate as sedation can depress respiratory function and worsen the condition.
Question 8 of 9
Continuous venovenous hemodialysis is used to
Correct Answer: D
Rationale: The correct answer is D because continuous venovenous hemodialysis combines ultrafiltration, convection, and dialysis techniques. Ultrafiltration removes excess fluid, convection helps in removing solutes, and dialysis involves the diffusion of solutes across a semipermeable membrane. This comprehensive approach ensures effective removal of both fluid and solutes in critically ill patients. Incorrect Answer Analysis: A: Removing fluids and solutes through convection alone is not the complete process in continuous venovenous hemodialysis. B: While volume overload is addressed, continuous venovenous hemodialysis involves more than just removing plasma water. C: Adding dialysate is not the primary method in continuous venovenous hemodialysis; it involves ultrafiltration, convection, and dialysis techniques.
Question 9 of 9
A client with osteoarthritis is given a new prescription for a nonsteroidal anti-inflammatory drug (NSAID). The client asks the nurse, 'How is this medication different from the acetaminophen I have been taking?' Which information about the therapeutic action of NSAIDs should the nurse provide?
Correct Answer: B
Rationale: The correct answer is B: Provide anti-inflammatory response. NSAIDs work by inhibiting the enzyme cyclooxygenase, thereby reducing inflammation, pain, and fever. This is different from acetaminophen, which primarily acts as a pain reliever and fever reducer but lacks significant anti-inflammatory properties. Explanation of why other choices are incorrect: A: Are less expensive - Cost is not related to the therapeutic action of NSAIDs. C: Increase hepatotoxic side effects - While NSAIDs can have adverse effects on the liver, hepatotoxicity is not a primary therapeutic action of these drugs. D: Cause gastrointestinal bleeding - While NSAIDs can increase the risk of gastrointestinal bleeding, this is a potential side effect rather than the primary therapeutic action.
