Critical Care Nursing Cardiac Questions

Correct Answer: B

Rationale: The correct answer is B: Increase the IV fluid infusion per protocol. Low CVP post-abdominal aortic aneurysm surgery could indicate hypovolemia, which requires fluid resuscitation. Increasing IV fluid infusion helps restore intravascular volume, improve tissue perfusion, and prevent hypotension. Administering diuretics (A) would worsen hypovolemia. Documenting (C) is important but not the priority when the patient needs immediate intervention. Elevating the head of the bed (D) may help with venous return but is not the priority over addressing hypovolemia.

Correct Answer: D

Rationale: The correct answer is D because the client's medical chart is the property of the hospital, but the client has the right to a copy of the information. By offering to make a copy of the chart for the client, the nurse respects the client's autonomy while also ensuring that the hospital maintains the original medical record. This response balances the client's rights with legal and ethical considerations. Choice A is incorrect because the hospital is legally obligated to maintain the client's medical record even if the client leaves against medical advice. Choice B is incorrect as it denies the client access to their medical information, which goes against the principle of patient autonomy. Choice C is also incorrect as it does not address the client's request for a copy of their chart.

Correct Answer: B

Rationale: The correct answer is B. The patient's pH of 7.30 indicates acidosis, PaCO2 of 38 mm Hg is low, and HCO3 of 16 mEq/L is also low, suggesting metabolic acidosis. This finding requires immediate action as untreated acidosis can lead to serious complications. Choice A (morning serum blood glucose of 128 mg/dL) is within normal range and does not require immediate action. Choice C (pulmonary artery temperature of 97.8�F) is a normal temperature and does not require immediate action. Choice D (central venous pressure of 8 mm Hg) is within normal range and does not require immediate action.

Correct Answer: A

Rationale: The correct answer is A: Advance directive. An advance directive is a legal document that outlines a person's wishes regarding medical treatment and care at the end of life. It allows individuals to specify their preferences for medical interventions if they become unable to communicate. Summary of other choices: B: Guardianship ad item - This does not specifically pertain to an individual's end-of-life care wishes. C: Healthcare proxy - While similar to an advance directive, a healthcare proxy specifically designates a person to make medical decisions on behalf of the individual, rather than specifying their own wishes. D: Power of attorney - This grants someone the authority to make legal decisions on behalf of the individual, but it does not specifically address end-of-life care preferences.

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.
