Critical Care Nursing Cardiac Questions Questions

Question 1 of 5

The nurse admits a terminally ill patient to the hospital. What is the first action that the nurse should complete when planning this patient care?

Correct Answer: A

Rationale: The correct answer is A because determining the patient's wishes regarding end-of-life care is crucial in providing patient-centered care and ensuring that the patient's preferences are respected. By understanding the patient's preferences, healthcare providers can tailor the care plan to align with the patient's values and goals. This helps in promoting autonomy, dignity, and quality of life for the patient. Choices B, C, and D are incorrect because although addressing family issues, discussing grief, and encouraging the patient to express fears are important aspects of caring for a terminally ill patient, they are not the first action that should be completed. Prioritizing the patient's wishes ensures that the care plan is centered around the patient's needs and preferences, which is essential in providing holistic and patient-centered care.

Question 2 of 5

The nurse cares for an adolescent patient who is dying. The patient�s parents are interested in organ donation and ask the nurse how the decision about brain death is made. Which response by the nurse is most appropriate?

Correct Answer: C

Rationale: The correct answer is C: Brain death has occurred if there is no breathing and certain reflexes are absent. Brain death is defined as the irreversible cessation of all functions of the entire brain, including the brainstem. The absence of breathing and certain reflexes, such as no response to painful stimuli or no pupillary response to light, are key indicators of brain death. This definition is crucial for determining eligibility for organ donation. Incorrect choices: A: Brain death occurs if a person is flaccid and unresponsive. Flaccidity and unresponsiveness are not specific criteria for diagnosing brain death. B: If CPR is ineffective in restoring a heartbeat, the brain cannot function. The absence of a heartbeat alone does not indicate brain death. D: If respiratory efforts cease and no apical pulse is audible, brain death is present. Respiratory cessation and the absence of pulse are not definitive signs of brain death.

Question 3 of 5

Which statement regarding ethical concepts is true?

Correct Answer: C

Rationale: Rationale: Choice C is correct because a surrogate is indeed a competent adult designated to make healthcare decisions for an incapacitated person. This individual is typically chosen by the person themselves through a legal document like a healthcare proxy. This ensures that someone trusted can make important decisions when the person is unable to do so. Choices A, B, and D are incorrect because a living will and healthcare proxy serve different purposes, a signed donor card does not guarantee organ donation in the event of brain death (medical criteria are also required), and a persistent vegetative state is different from brain death (brain death implies irreversible cessation of brain function while a vegetative state involves some level of brain function).

Question 4 of 5

To verify the correct placement of an oral endotracheal tube (ET) after insertion, the best initial action by the nurse is to:

Correct Answer: D

Rationale: The correct answer is D because using an end-tidal CO2 monitor is the most reliable method to confirm correct endotracheal tube placement in the trachea. This method detects exhaled CO2, indicating proper tube placement in the trachea. It is a quick and efficient way to confirm placement without delay, reducing the risk of complications. A: Auscultating for bilateral breath sounds is not as reliable because breath sounds may be heard even if the tube is misplaced. B: Obtaining a portable chest x-ray is not the best initial action as it takes time and delays confirming tube placement. C: Observing chest movement may not provide conclusive evidence of proper tube placement and can lead to misinterpretation. In summary, using an end-tidal CO2 monitor is the most accurate and efficient method to verify correct endotracheal tube placement compared to the other options.

Question 5 of 5

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.
