Critical Care Nursing Cardiac Questions

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: The correct answer is C: Insertion of a vena cava filter. This is a strategy for preventing thromboembolism in patients at risk who cannot take anticoagulants. The vena cava filter prevents blood clots from traveling to the lungs by trapping them in the inferior vena cava. It is a mechanical device that does not interfere with the body's clotting process. Explanation of why other choices are incorrect: A: Administration of two aspirin tablets every 4 hours is not an effective strategy for preventing thromboembolism in high-risk patients. Aspirin is an antiplatelet agent and may not be sufficient for preventing blood clots in these patients. B: Infusion of thrombolytics is used for breaking down blood clots that have already formed, not for prevention. It is not a suitable option for preventing thromboembolism in at-risk patients. D: Subcutaneous heparin administration every 12

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.

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.

Correct Answer: A

Rationale: The correct answer is A because renin activates the renin-angiotensin-aldosterone cascade, which ultimately leads to vasoconstriction, increased blood pressure, and aldosterone release to increase sodium and water reabsorption. Renin does not suppress angiotensin production (B), decrease sodium reabsorption (C), or inhibit aldosterone release (D), as these actions would counteract its role in blood pressure regulation.
