Critical Care Nursing Cardiac Questions Questions
Question 1 of 9
A patient with respiratory failure has arterial pressure-based cardiac output (APCO) monitoring and is receiving mechanical ventilation with peak end-expiratory pressure (PEEP) of 12 cm H2O. Which information indicates that a change in the ventilator settings may be required?
Correct Answer: A
Rationale: The correct answer is A. A decrease in the arterial pressure (hypotension) with a low diastolic pressure (46 mmHg) may indicate inadequate perfusion, possibly due to inadequate cardiac output from the mechanical ventilation. This suggests that a change in ventilator settings may be required to improve oxygenation and perfusion. Option B is incorrect because a heart rate of 58 beats/minute alone does not provide direct information on the patient's hemodynamic status. Option C is incorrect as an increased stroke volume would usually be a positive indicator; it does not necessarily indicate a need for changing the ventilator settings. Option D is incorrect as a stroke volume variation of 12% is within normal limits and does not necessarily require a change in ventilator settings.
Question 2 of 9
The nurse is assessing a child's weight and height during a clinic visit prior to starting school. The nurse plots the child's weight on the growth chart and notes that the child's weight is in the 95th percentile for the child's height. What action should the nurse take?
Correct Answer: A
Rationale: The correct answer is A: Question the type and quantity of foods eaten in a typical day. When a child's weight is in the 95th percentile for their height, it indicates possible overweight or obesity. To address this, the nurse should assess the child's dietary habits to identify any unhealthy eating patterns contributing to excess weight. By questioning the type and quantity of foods eaten, the nurse can provide appropriate guidance on nutrition and healthy eating habits. Summary: B: Encouraging additional snacks may further contribute to weight gain and is not recommended without knowing the current eating habits. C: Recommending a high intake of whole milk may increase calorie intake and potentially worsen the weight concern. D: Assessing for signs of poor nutrition, such as a pale appearance, is important but not directly addressing the weight concern in this scenario.
Question 3 of 9
Which of the following factors predispose the critically ill patient to pain and anxiety? (Select all that apply.)
Correct Answer: A
Rationale: The correct answer is A: Inability to communicate. Critically ill patients often experience pain and anxiety due to their inability to effectively communicate their needs and discomfort. This can lead to unaddressed pain and increased anxiety levels. Choices B, C, and D are incorrect because while invasive procedures, monitoring devices, and preexisting conditions can contribute to pain and anxiety in critically ill patients, they are not factors that directly predispose patients to these issues. It is the lack of communication that significantly hinders the ability to address and manage pain and anxiety effectively in these patients.
Question 4 of 9
How should the nurse interprets these blood gas values? 2 3
Correct Answer: C
Rationale: The correct interpretation is uncompensated respiratory acidosis (Choice C) based on the values. Step 1: Evaluate pH - pH is <7.35, indicating acidosis. Step 2: Determine PaCO2 - PaCO2 is >45 mmHg, indicating respiratory cause. Step 3: Check HCO3- - HCO3- is within normal range, indicating uncompensated state. Choices A, B, and D are incorrect because they do not align with the given blood gas values.
Question 5 of 9
A Muslim woman is admitted to the ICU after suffering severe burns over most of her body. Which of the following would be the most appropriate measure for the nurse, a woman, to take in respect for the cultural practices of this patient?
Correct Answer: D
Rationale: The correct answer is D because it demonstrates respect for the patient's autonomy and individual preferences. By asking the patient's husband about religious and cultural preferences, the nurse acknowledges the importance of involving the family in decision-making and shows sensitivity to the patient's beliefs. This approach promotes cultural competence and patient-centered care. Choice A is incorrect because insisting on a female doctor may not align with the patient's preferences and may limit the available medical staff. Choice B is also incorrect as dietary restrictions are not necessarily the most pressing issue in this scenario. Choice C is incorrect as it assumes a cultural practice without verifying the patient's specific preferences and may not be necessary or appropriate in this context.
Question 6 of 9
What term is used to describe a specific request made by a competent person that directs medical care related to life-prolonging procedures if the pa tient loses capacity to make decisions?
Correct Answer: D
Rationale: The correct answer is D, Living will. A living will is a legal document that outlines a person's preferences for medical treatment if they become unable to communicate their wishes. It specifically addresses life-prolonging procedures. Option A, Do not resuscitate order, is a specific directive to not perform CPR in case of cardiac arrest, not a comprehensive medical care directive. Option B, Healthcare proxy, is a person designated to make medical decisions on behalf of a patient who is unable to do so, not the specific directive itself. Option C, Informed consent, refers to the process of obtaining permission from a patient before conducting a healthcare intervention, not a directive for life-prolonging procedures.
Question 7 of 9
Which statement reflects adherence to current recommendations concerning open visitation policies?
Correct Answer: C
Rationale: The correct answer is C because it reflects patient-centered care by involving patients and families in decision-making. Collaborating with them on visitation preferences promotes a supportive environment. Choice A restricts animal visitation, not addressing human visitors. Choice B limits visitation during specific times, not individualized. Choice D imposes restrictions based on age, not on patient/family preferences. Therefore, Choice C is the most aligned with current recommendations for open visitation policies.
Question 8 of 9
The nurse is caring for a patient following insertion of a left subclavian central venous catheter (CVC). Which action by the nurse best reduces th e risk of catheter-related bloodstream infection (CRBSI)?
Correct Answer: A
Rationale: The correct answer is A: Review daily the necessity of the central venous catheter. This action reduces the risk of CRBSI by promoting early removal of unnecessary catheters, which is a key strategy in preventing infections. Unnecessary catheters increase the risk of infection due to prolonged exposure to the patient's skin flora and possible contamination during insertion. Reviewing daily ensures the catheter is only kept when necessary, minimizing the duration of catheter use and reducing the chances of infection. Summary of other choices: B: Cleansing the insertion site daily with isopropyl alcohol is important for maintaining skin integrity but does not directly reduce the risk of CRBSI. C: Changing the pressurized tubing system and flush bag daily is important for maintaining catheter patency but does not directly reduce the risk of CRBSI. D: Maintaining a pressure of 300 mm Hg on the flush bag is important for proper catheter function but does not directly reduce the risk of CR
Question 9 of 9
A hospice patient develops a pressure ulcer despite proper repositioning. What should the nurse include in the care plan?
Correct Answer: A
Rationale: The correct answer is A because implementing more aggressive wound care strategies is essential for managing pressure ulcers effectively. This includes proper wound cleaning, debridement, and dressing changes to promote healing. Adequate hydration and nutrition (choice B) are important but may not directly address the pressure ulcer. Discussing prognosis and expected outcomes (choice C) is important but may not directly impact wound healing. Encouraging increased physical activity (choice D) may be contraindicated due to the patient's condition.
