Critical Care Nursing Cardiac Questions Questions
Question 1 of 9
Noninvasive diagnostic procedures used to determine kidney function include which of the following? (Select all that apply.)
Correct Answer: A
Rationale: The correct answer is A: Kidney, ureter, bladder (KUB) x-ray. This procedure is noninvasive and commonly used to assess kidney function by visualizing the size, shape, and position of the kidneys. Renal ultrasound is also noninvasive and can provide detailed images of the kidneys. However, MRI and IVP are more invasive procedures that involve the use of contrast agents and are not typically used solely for diagnostic purposes to assess kidney function. Overall, KUB x-ray and renal ultrasound are the preferred noninvasive options for evaluating kidney function.
Question 2 of 9
Which nursing interventions would best support the family of a critically ill patient?
Correct Answer: B
Rationale: The correct answer is B because giving regular condition updates promotes transparency and communication, reducing anxiety for the family. This intervention helps them stay informed and involved in the patient's care. Choice A may lead to caregiver fatigue and is not sustainable. Choice C limits family support and may increase stress. Choice D focuses on comfort but does not address the family's need for information.
Question 3 of 9
The patient is admitted to the unit with the diagnosis of rhabdomyolysis. The patient is started on intravenous (IV) fluids and IV mannitol. What action by the nurse is best?
Correct Answer: B
Rationale: The correct answer is B: Assess the patient’s lungs. Rhabdomyolysis can lead to acute kidney injury due to myoglobin release from damaged muscle cells. IV fluids and mannitol are given to prevent kidney damage by promoting myoglobin excretion. Assessing the patient’s lungs is crucial to monitor for potential complications such as acute respiratory distress syndrome (ARDS) which can occur as a result of rhabdomyolysis. This assessment helps to ensure early detection and prompt intervention if respiratory issues arise. Summary of Incorrect Choices: A: Assess the patient’s hearing - This is not directly related to rhabdomyolysis or its treatment. C: Decrease IV fluids once the diuretic has been administered - Decreasing IV fluids can exacerbate kidney injury in rhabdomyolysis. D: Give extra doses before giving radiological contrast agents - Mannitol is not routinely given before radiological contrast agents in the context of rhabdomyolysis management.
Question 4 of 9
Which interventions may be included during “terminal we aning”? (Select all that apply.)
Correct Answer: B
Rationale: The correct answer is B because during terminal weaning, the artificial ventilation is discontinued while maintaining the artificial airway to ensure comfort and support. This allows the patient to breathe on their own with support as needed. Explanation: 1. Option A: Complete extubation following ventilator withdrawal may not be suitable during terminal weaning as it involves removing the breathing tube entirely. 2. Option C: Discontinuation of anxiolytic and pain medications may not always be appropriate during terminal weaning as it depends on the patient's comfort needs. 3. Option D: Titration of ventilator support based on blood gas determinations is not typically done during terminal weaning as the focus is on gradual withdrawal of ventilation support while maintaining comfort.
Question 5 of 9
An advantage of peritoneal dialysis is that
Correct Answer: B
Rationale: The correct answer is B: a decreased risk of peritonitis exists. Peritoneal dialysis involves the insertion of a catheter into the peritoneal cavity, which can introduce bacteria and increase the risk of peritonitis. However, compared to hemodialysis, peritoneal dialysis has a lower risk of bloodstream infections and vascular access-related complications, leading to a decreased risk of peritonitis. This advantage makes peritoneal dialysis a favorable option for some patients. Incorrect choices: A: peritoneal dialysis is actually less time-intensive compared to hemodialysis. C: biochemical disturbances are corrected more gradually in peritoneal dialysis. D: the danger of hemorrhage is not specific to peritoneal dialysis.
Question 6 of 9
Which of the following is (are) official journal(s) of the A merican Association of Critical-Care Nurses? (Select all that apply.)
Correct Answer: A
Rationale: Step-by-step rationale: 1. The American Association of Critical-Care Nurses (AACN) publishes the American Journal of Critical Care (AJCC). 2. The AJCC is a peer-reviewed journal that covers critical care nursing practice, research, and education. 3. The content in AJCC aligns with AACN's mission and standards for critical care nursing. 4. Hence, AJCC is an official journal of AACN. Summary of other choices: - B: Critical Care Clinics of North America - Not an official journal of AACN. - C: Critical Care Nurse - Not an official journal of AACN. - D: Critical Care Nursing Quarterly - Not an official journal of AACN.

Question 8 of 9
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 9 of 9
In the critically ill patient, an incomplete assessment and/or management of pain or anxiety may be hampered by which of the following? (Select all that apply.)
Correct Answer: A
Rationale: Step-by-step rationale: 1. Administration of neuromuscular blocking agents can hinder pain or anxiety assessment as it paralyzes the patient, preventing them from communicating discomfort. 2. Delirium may affect the patient's ability to express pain or anxiety, but it does not directly impede assessment and management. 3. Effective nurse communication and assessment skills facilitate, rather than hamper, pain or anxiety assessment. 4. Nonverbal patients can still communicate pain or anxiety through nonverbal cues, so they do not necessarily hinder assessment.
