Critical Care Nursing Exam Questions Questions
Question 1 of 9
The patient is on intake and output (I&O), as well as daily weights. The nurse notes that output is considerably less than intake over the last shift, and daily weight is 1 kg more than yesterday. The nurse should
Correct Answer: C
Rationale: First, the nurse should assess the patient's lungs to rule out any potential respiratory issues causing fluid retention. This is crucial as the patient has signs of fluid imbalance with decreased output and increased weight. Assessing the lungs can help identify conditions like heart failure or pneumonia that may contribute to these changes. Drawing a trough level (choice A) is not a priority as it doesn't address the immediate concern of fluid imbalance. Placing the patient on fluid restriction (choice B) should only be done after identifying the cause of the imbalance. Inserting an indwelling catheter (choice D) is not necessary at this point as the issue is related to fluid balance, not urinary elimination.
Question 2 of 9
What is an early signs of the effect of hypoxemia on the nervous system?
Correct Answer: B
Rationale: The correct answer is B: Restlessness. When the body experiences hypoxemia (low oxygen levels), the brain is deprived of oxygen, leading to early signs such as restlessness. This is due to the brain's attempt to increase oxygen intake by increasing activity. Cyanosis (A) is a late sign of hypoxemia when oxygen levels are critically low. Tachycardia (C) and tachypnea (D) are compensatory mechanisms in response to hypoxemia, but they are not early signs affecting the nervous system directly.
Question 3 of 9
The nurse obtains the pulse rate of 89 beats/minute for an infant before administering digoxin (Lanoxin). Which action should the nurse take?
Correct Answer: A
Rationale: The correct answer is A. Infants typically have higher resting heart rates than adults, so a pulse rate of 89 beats/minute for an infant may indicate bradycardia. Digoxin can further lower the heart rate, leading to potential adverse effects like arrhythmias. Therefore, withholding the medication and contacting the healthcare provider is crucial to ensure the safety of the infant. Choice B is incorrect because administering digoxin without addressing the elevated pulse rate can be dangerous. Choice C is incorrect as assessing respiratory rate does not address the immediate concern of the elevated pulse rate. Choice D is also incorrect as waiting and giving half of the dosage may further exacerbate the situation.
Question 4 of 9
A patient who is receiving positive pressure ventilation is scheduled for a spontaneous breathing trial (SBT). Which finding by the nurse is most important to discuss with the health care provider before starting the SBT?
Correct Answer: A
Rationale: The correct answer is A: New ST segment elevation is noted on the cardiac monitor. This finding is concerning because it may indicate myocardial ischemia or infarction, which can be exacerbated by the physiological stress of weaning from mechanical ventilation. It is crucial to address any cardiac issues before initiating a spontaneous breathing trial to prevent potential cardiac complications during the weaning process. Explanation for why the other choices are incorrect: B: Enteral feedings being given through an orogastric tube are not contraindicated for starting a spontaneous breathing trial. C: Scattered rhonchi heard when auscultating breath sounds may indicate retained secretions but are not a contraindication for a spontaneous breathing trial. D: The use of HYDROmorphone to treat postoperative pain is not a contraindication for a spontaneous breathing trial unless it is causing respiratory depression, which would need to be addressed separately.
Question 5 of 9
Which nursing intervention would need to be corrected on a care plan for a patient in order to be consistent with the principles of effective end-of-life ca re?
Correct Answer: B
Rationale: Correct Answer: B Rationale: 1. Limiting visitation to reduce emotional distress contradicts the principles of effective end-of-life care, which emphasize holistic support for the patient and family. 2. Effective end-of-life care encourages open communication and emotional support from loved ones. 3. Limiting visitation may hinder emotional closure and support for both the patient and family. 4. Options A, C, and D align with effective end-of-life care by focusing on symptom management, education, and spiritual support for the patient and family.
Question 6 of 9
What strategies are appropriate for preventing deep vein tharboirbm.cbomo/steisst (DVT) and pulmonary embolus (PE) in an at-risk patient? (Select all that apply.) WWW .THENURSINGMASTERY.COM
Correct Answer: A
Rationale: The correct answer is A: Graduated compression stockings. These stockings help prevent blood from pooling in the legs, reducing the risk of DVT and PE. They improve circulation and reduce venous stasis. Option B, heparin, is used for treatment, not prevention. Option C, sequential compression devices, help prevent DVT but are not as effective as compression stockings. Option D, strict bed rest, can actually increase the risk of DVT by reducing blood flow.
Question 7 of 9
The family members are excited about being transferring t heir loved one from the critical care unit to the intermediate care unit. However, they are also fearful of the change in environment and nursing staff. To reduce relocation stress, the nurse ca n implement what intervention? (Select all that apply.)
Correct Answer: A
Rationale: The correct answer is A (Arranging for the nurses on the intermediate care unit to give the family a tour of the new unit) because it helps familiarize the family with the new environment, alleviating their fears. The tour allows them to see where their loved one will be cared for, meet the nursing staff, and ask any questions they may have. This intervention promotes a smooth transition, reduces anxiety, and builds trust. Choice B is incorrect because delaying the transfer doesn't address the fear of change and can prolong stress. Choice C is incorrect as proximity to the nurse's station may not necessarily reduce relocation stress for the family. Choice D is incorrect because meeting the new nurse in the current unit may not provide the same level of comfort and preparation compared to physically visiting the new unit.
Question 8 of 9
The critical care nurse knows that in critically ill patients, renal dysfunction
Correct Answer: B
Rationale: The correct answer is B. Renal dysfunction is common in critically ill patients due to various factors like sepsis, hypotension, and nephrotoxic medications. This affects nearly two thirds of patients, making it a significant issue in critical care. Choices A, C, and D are incorrect. A is wrong because renal dysfunction is not rare in critically ill patients. C is incorrect as renal replacement therapy does not guarantee low mortality rates. D is inaccurate as renal dysfunction can have a significant impact on morbidity, mortality, and quality of life in critically ill patients.
Question 9 of 9
The nurse is concerned that the patient will pull out the en dotracheal tube. As part of the nursing management, the nurse should obtain an order for what intervention?
Correct Answer: A
Rationale: The correct answer is A. A Posey-type vest is a restraint designed to prevent patients from pulling out medical devices like endotracheal tubes, ensuring their safety. It is a less restrictive option compared to wrist restraints and sedatives (B and C), which can have adverse effects and may not directly address the concern of tube removal. Using a Posey-type vest promotes patient autonomy by allowing some movement while still providing the necessary protection.
