Critical Care Nursing Cardiac Questions

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.

Correct Answer: C

Rationale: The correct answer is C because providing specific information such as descending trends in parameters helps the family understand the patient's condition objectively. This allows them to prepare emotionally and make informed decisions. Option A is incorrect because false hope should not be given. Option B is not the best approach as the nurse should still provide some information to the family. Option D is inappropriate and insensitive as it focuses on funeral arrangements rather than addressing the family's concerns about the patient's condition.

Correct Answer: A

Rationale: The correct answer is A: Elevated creatinine. Ibuprofen can cause kidney damage, leading to elevated creatinine levels. This is because ibuprofen is metabolized in the kidneys, and prolonged use can impair kidney function. Elevated platelet count (B), elevated white blood count (C), and low liver enzymes (D) are not typically associated with ibuprofen use. Platelet count and white blood count are more related to inflammation or infection, while low liver enzymes are not a common side effect of ibuprofen.

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).

Correct Answer: C

Rationale: The correct answer is C: Moral distress. In this scenario, the nurse is experiencing conflicting moral values between the decision made for the patient and their own beliefs. This internal conflict leads to moral distress, a common response when healthcare professionals feel unable to act in accordance with their ethical beliefs. This can lead to emotional turmoil, frustration, and moral residue. A: A sense of abandonment is incorrect because the nurse is still caring for the patient, so there is no physical abandonment. B: Increased family stress is incorrect as the nurse's internal conflict does not directly impact family stress. D: A sense of negligence is incorrect as negligence implies failure to provide proper care, which is not the case here.
