Critical Care Nursing NCLEX Questions Questions
Question 1 of 5
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 5
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.
Question 3 of 5
A patient is admitted to the hospital with multiple trauma aabnirdb .ceoxmte/tensst ive blood loss. The nurse assesses vital signs to be BP 80/50 mm Hg, heart rate 135 beats/min, respirations 36 breaths/min, cardiac output (CO) of 2 L/min, systemic vas cular resistance of 3000 dynes/sec/cm5, and a hematocrit of 20%. The nurse anticip ates administration of which the following therapies or medications?
Correct Answer: C
Rationale: The correct answer is C: Dobutamine infusion. In this scenario, the patient is experiencing hypovolemic shock due to significant blood loss, resulting in low blood pressure, tachycardia, and low cardiac output. Dobutamine is a positive inotropic agent that increases cardiac contractility and output, helping to improve tissue perfusion. Blood transfusion (A) is a common intervention for hypovolemic shock, but in this case, the patient's hematocrit is low, indicating dilutional anemia rather than acute blood loss, so addressing the cardiac output is more urgent. Furosemide (B) is a diuretic that would exacerbate the hypovolemia and worsen the patient's condition. Dopamine (D) is a vasopressor that primarily increases blood pressure, but in this case, the patient's low cardiac output is the main concern, making dobutamine a more appropriate choice.
Question 4 of 5
Family assessment can be challenging and each nurse may obtain additional information regarding family structure and dynamics. What is the best way to share this information from shift to shift?
Correct Answer: B
Rationale: The correct answer is B because developing a standardized reporting form for family information that is incorporated into the patient's medical record ensures consistency and accuracy in sharing vital details about family structure and dynamics from shift to shift. This method allows all healthcare providers to access the information easily and update it as needed, promoting continuity of care and comprehensive understanding of the family's needs. Choices A, C, and D are incorrect because: A: Creating an informal family information sheet may lead to inconsistencies in the information shared among healthcare providers and may not be updated regularly. C: Requiring only the charge nurse to have detailed information may result in information silos and lack of accessibility for all team members. D: Discussing family dynamics as part of the change-of-shift report may lead to important details being missed or forgotten, compromising the quality of care provided.
Question 5 of 5
The nurse educator is evaluating the care that a new registered nurse (RN) provides to a patient receiving mechanical ventilation. Which action by the new RN indicates the need for more education?
Correct Answer: D
Rationale: The correct answer is D because positioning the patient with the head of the bed at 10 degrees is incorrect for a patient receiving mechanical ventilation. The optimal position for such patients is to elevate the head of the bed to 30-45 degrees to prevent aspiration and improve oxygenation. Option A is incorrect as increasing FIO2 before suctioning is appropriate to ensure adequate oxygenation. Option B is incorrect as securing a bite block in place using adhesive tape is a standard practice to prevent the patient from biting on the endotracheal tube. Option C is incorrect as asking for assistance to reposition the endotracheal tube shows the RN is aware of the importance of proper placement to ensure effective ventilation.
