ATI RN
Critical Care Nursing Cardiac Questions Questions
Question 1 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 2 of 5
A patient who has experienced blunt abdominal trauma during a motor vehicle collision is complaining of increasing abdominal pain. The nurse will plan to teach the patient about the purpose of:
Correct Answer: B
Rationale: The correct answer is B: Abdominal ultrasonography. This is because ultrasonography is a non-invasive imaging technique that can quickly evaluate for internal injuries such as organ damage or bleeding in patients with blunt abdominal trauma. It is a rapid and effective diagnostic tool to assess the extent of injury and guide further management. Peritoneal lavage (A) is an invasive procedure used in trauma settings to detect intra-abdominal bleeding but is not typically used for teaching purposes. Nasogastric tube placement (C) is used for decompression and drainage in certain conditions but is not relevant for assessing abdominal trauma. Magnetic resonance imaging (MRI) (D) is not typically used as the initial imaging modality for acute trauma due to time constraints and its limited availability in emergency settings.
Question 3 of 5
A 20-year-old patient arrives in the emergency department (ED) several hours after taking 25 to 30 acetaminophen (Tylenol) tablets. Which action will the nurse plan to take?
Correct Answer: A
Rationale: The correct answer is A: Give N-acetylcysteine (Mucomyst). N-acetylcysteine is the antidote for acetaminophen overdose. It helps replenish glutathione, which is depleted by acetaminophen metabolism. This prevents liver damage. Choice B, chelation therapy, is not indicated for acetaminophen overdose. Choice C, oxygen therapy, is not directly related to acetaminophen overdose treatment. Choice D, drinking water, will not address the overdose and may not be safe in high doses. Therefore, the best course of action is to administer N-acetylcysteine to prevent liver damage in acetaminophen overdose.
Question 4 of 5
An unresponsive 79-year-old is admitted to the emergency department (ED) during a summer heat wave. The patient’s core temperature is 105.4°F (40.8°C), blood pressure (BP) 88/50, and pulse 112. The nurse initially will plan to:
Correct Answer: A
Rationale: The correct answer is A: Apply wet sheets and a fan to the patient. This is the initial treatment for hyperthermia to aid in lowering the body temperature. Wet sheets help in evaporative cooling, while a fan enhances heat loss through convection. This approach is crucial in managing heat-related illnesses quickly. Choices B, C, and D are incorrect as they do not directly address the urgent need to reduce the patient's elevated core temperature. Providing O2, IV fluids, or acetaminophen can be considered later in the management, but the priority is to rapidly lower the body temperature in a hyperthermic patient to prevent further complications.
Question 5 of 5
The nurse cares for a terminally ill patient who is experiencing pain that is continuous and severe. How should the nurse schedule the administration of opioid pain medications?
Correct Answer: A
Rationale: The correct answer is A: Give around-the-clock routine administration of analgesics. This is the best approach for managing continuous and severe pain in a terminally ill patient. By providing scheduled doses of opioid pain medications, the nurse ensures a consistent level of pain relief, preventing peaks and troughs in pain control. This approach also helps in preventing the patient from experiencing unnecessary suffering. Choice B (PRN doses) may lead to inadequate pain control as the patient may wait too long before requesting medication. Choice C (keeping the patient sedated) is not appropriate as the goal is pain management, not sedation. Choice D (balancing pain control and respiratory rate) is important, but the priority should be on effectively managing the pain first.
