Critical Care Nursing Questions and Answers PDF

Correct Answer: D

Rationale: The correct answer is D: Pulmonary artery wedge pressure (PAWP). This is crucial in monitoring a patient with a large anterior wall myocardial infarction as it provides information on left ventricular function and fluid status. A high PAWP may indicate left ventricular failure or fluid overload, requiring immediate intervention. A: Central venous pressure (CVP) is not as specific for assessing left ventricular function and may not provide accurate information in this scenario. B: Systemic vascular resistance (SVR) is important in assessing systemic blood flow, but it may not directly indicate left ventricular function in this case. C: Pulmonary vascular resistance (PVR) is more relevant in conditions affecting the pulmonary circulation and may not be as immediately informative in assessing left ventricular function in this context.

Correct Answer: D

Rationale: The correct answer is D because the presence of red blood cells and albumin in the urine indicates possible kidney damage from the blunt trauma. This is concerning as it may suggest renal injury or dysfunction. A: Creatinine levels in the urine being similar to blood levels is normal as creatinine is filtered by the kidneys. B: Sodium and chloride being present in the urine is expected as they are components of urine. C: Urine uric acid levels matching serum levels is common as uric acid is excreted by the kidneys. In summary, the presence of red blood cells and albumin in the urine is abnormal and indicates potential kidney damage, making it the correct answer.

Correct Answer: D

Rationale: The correct answer is D because initiating the alcohol withdrawal protocol shows an understanding of managing a patient at risk for alcohol withdrawal syndrome. This protocol involves carefully monitoring the patient's symptoms, providing appropriate medications, and ensuring a safe environment. Option A is incorrect as it downplays the seriousness of alcohol withdrawal. Option B is incorrect as there are assessment tools available for identifying alcohol withdrawal. Option C is incorrect as pain management should be tailored to the individual's needs, not necessarily lessened due to alcohol withdrawal risk.

Correct Answer: A

Rationale: The correct answer is A because it demonstrates effective handoff communication by involving key stakeholders (nephrology consultant physician), requesting specific patient updates, and collaborating on patient care tasks (placing a central line). This scenario promotes continuity of care and ensures important information is shared. Explanation for why other choices are incorrect: B: High noise level disrupts communication and can lead to errors or omissions in handoff information. C: While using a standardized checklist can be beneficial, it alone does not guarantee effective communication if not utilized properly or if key information is missed. D: Conducting reports at the patient's bedside is beneficial for patient involvement but may not address the need for involving relevant healthcare providers like the consultant physician in the handoff process.

Correct Answer: C

Rationale: The correct answer is C: notify the provider immediately. The absence of bruit, thrill, and palpable distal pulses in a new arteriovenous fistula suggests potential complications like thrombosis or stenosis, requiring urgent intervention. Notifying the provider promptly allows for timely assessment and appropriate management to prevent further complications. Summary: A: Reassessing the patient in an hour may delay necessary intervention for a potentially serious issue. B: Raising the arm above the level of the patient�s heart does not address the underlying problem and may not improve the situation. D: Applying warm packs to the fistula site is not the appropriate intervention for the absence of bruit and thrill and may not address the underlying cause.
