Critical Care Nursing Cardiac Questions Questions
Question 1 of 5
A 10-year-old female patient in ICU receiving chemotherapy has requested that her dog be allowed to visit her. She is currently sharing a room with another patient. The nurse knows that the hospital does allow for pet visits with owners, but has strict guidelines. Which of the following scenarios is most likely to be permitted?
Correct Answer: A
Rationale: The correct answer is A because it follows the hospital's guidelines for pet visits. It allows the dog to be brought in on a leash, which ensures control and safety during the visit. The 20-minute duration is appropriate to limit potential stress on the patient and other individuals in the room. Additionally, having the father bring the dog in maintains consistency with the hospital's policy of pet visits with owners. Choices B, C, and D are incorrect because they do not adhere to the hospital's guidelines. Choice B allows for an overnight stay, which is typically not permitted due to potential disruptions and hygiene concerns. Choice C mentions vaccinations but overlooks other important factors like leash control and visit duration. Choice D suggests waiting until the girl is moved to a private room, which may not align with the hospital's policy of allowing pet visits with owners.
Question 2 of 5
The nurse educator is evaluating the performance of a new registered nurse (RN) who is providing care to a patient who is receiving mechanical ventilation with 15 cm H2O of peak end-expiratory pressure (PEEP). Which action indicates that the new RN is safe?
Correct Answer: B
Rationale: The correct answer is B: The RN uses a closed-suction technique to suction the patient. This is the safe action because closed-suction technique minimizes the risk of ventilator-associated infections by maintaining a closed system during suctioning, reducing the exposure to pathogens. Closed-suction systems also help maintain lung compliance and oxygenation levels during the suctioning process. Rationale: Option A is incorrect because suctioning every 1 to 2 hours may be too frequent and can lead to hypoxia and mucosal damage. Option C is incorrect as taping the connection between the ventilator tubing and ET can interfere with the proper functioning of the ventilator and increase the risk of disconnection. Option D is incorrect because changing ventilator circuit tubing routinely every 48 hours is not evidence-based practice and can increase the risk of contamination and unnecessary costs.
Question 3 of 5
The nurse is caring for a patient in the critical care unit whaobi,r ba.cfotemr/ tebset ing declared brain dead, is being managed by the OPO transplant coordinator. Thir ty minutes into the shift, assessment by the nurse includes a blood pressure 75/50 mm Hg, hear t rate 85 beats/min, and respiratory rate 12 breaths/min via assist/control ventilation. The oxygen saturation (SpO ) is 99% and 2 core temperature 93.8� F. Which primary care provider ord er should the nurse implement first?
Correct Answer: C
Rationale: The correct answer is C: Begin phenylephrine (Neo-Synephrine) for systolic BP < 90 mm Hg. The nurse should implement this order first because the patient's low blood pressure (75/50 mm Hg) indicates hypotension, which can lead to inadequate perfusion to vital organs. Phenylephrine is a vasoconstrictor that can help increase the patient's blood pressure and improve perfusion. It is crucial to address hypotension promptly to prevent further complications. Choice A is incorrect because maintaining the patient's temperature above 96.8�F is not the most urgent concern in this scenario. Choice B is incorrect as obtaining a basic metabolic panel every 4 hours is not the immediate priority when the patient is experiencing hypotension. Choice D is incorrect as drawing arterial blood gas every 4 hours is not the most urgent intervention needed to address the patient's low blood pressure.
Question 4 of 5
The nurse is caring for a patient with an admitting diagnosis of congestive failure. While attempting to obtain a pulmonary artery occlusion pressure in the supine position, the patient becomes anxious and tachypneic. What is the best action by the nurse?
Correct Answer: D
Rationale: The correct answer is D: Elevate the head of the bed 45 degrees while recording pressures. Rationale: 1. Elevating the head of the bed will help improve the patient's breathing by reducing the pressure on the diaphragm. 2. This position will also help alleviate the patient's anxiety and tachypnea, promoting better oxygenation. 3. Recording pressures in this position will provide accurate data for monitoring the patient's condition. Summary: A: Limiting the supine position to 10 seconds does not address the underlying issues causing the patient's anxiety and tachypnea. B: Administering anxiety medications without addressing the positioning issue may not effectively manage the patient's symptoms. C: Encouraging the patient to take slow deep breaths is helpful, but changing the position of the patient is more crucial in this situation.
Question 5 of 5
When assisting with the placement of a pulmonary artery (PA) catheter, the nurse notes that the catheter is correctly placed when the monitor shows a:
Correct Answer: D
Rationale: Step-by-step rationale for Answer D being correct: 1. PA catheter measures PA pressures. 2. PAWP reflects left atrial pressure. 3. Correct placement shows typical PAWP tracing. 4. PA pressure waveform (A) is not specific to PAWP. 5. Systemic arterial pressure tracing (B) is unrelated. 6. Systemic vascular resistance tracing (C) is not monitored by PA catheter.
