Nursing Elites

1. A 65-year-old man is admitted to the intensive care unit from the operating room after a triple coronary artery bypass graft. He is intubated and on a ventilator. Lactic acid levels were normal postoperatively, but now they are rising. The increased level could be an indication of:

• A. excessive sedation
• B. bowel ischemia
• C. excessive volume infusion in the operating room
• D. mild hypothermia postoperatively

Correct answer: B

Rationale: In this scenario, the rising lactic acid levels in a 65-year-old man after a coronary artery bypass graft could indicate bowel ischemia. Bowel ischemia can lead to anaerobic metabolism, causing an increase in lactic acid levels. Excessive sedation may cause respiratory depression but would not directly lead to rising lactic acid levels. Excessive volume infusion in the operating room might cause fluid overload but would not typically result in rising lactic acid levels. Mild hypothermia postoperatively could lead to shivering and increased oxygen consumption, but it is less likely to be the primary cause of rising lactic acid levels in this context.

2. Which of the following is not included in the care plan of a client with moderate cognitive impairment involving dementia of the Alzheimer’s type?

• A. Daily structured schedule
• B. Positive reinforcement for performing activities of daily living
• C. Stimulating environment
• D. Use of validation techniques

Correct answer: C

Rationale: In the care plan for a client with moderate cognitive impairment involving Alzheimer's type dementia, a stimulating environment is not included as it can potentially increase confusion. Therefore, it is important to provide a familiar, structured, and predictable environment to reduce stress and disorientation. Daily structured schedules help in maintaining routine and familiarity, positive reinforcement encourages engagement in activities, and validation techniques help in communicating effectively with the client by acknowledging their feelings and reality orientation.

3. Women who have breast cancer due to a BRCA1 gene mutation are usually:

• A. positive for human epidermal growth factor receptor 1 and 2.
• B. negative for estrogen receptor.
• C. positive for estrogen receptor, progesterone receptor, and human epidermal growth factor receptor 2.
• D. negative for estrogen receptor, progesterone receptor, and human epidermal growth factor receptor 2.

Correct answer: D

Rationale: Women with breast cancer due to a BRCA1 gene mutation commonly have a triple-negative breast cancer subtype, which means they are negative for estrogen receptor, progesterone receptor, and human epidermal growth factor receptor 2 (HER2). This subtype tends to be more aggressive and harder to treat. Choice A is incorrect as they are typically negative for HER2. Choice B is incorrect because they are usually negative for estrogen receptor. Choice C is incorrect as they are usually negative for progesterone receptor and HER2.

4. A client is admitted with a suspected aortic dissection. What is the priority nursing intervention?

• A. Administer antihypertensive medications as prescribed.
• B. Prepare the client for emergency surgery.
• C. Administer intravenous fluids to maintain blood pressure.
• D. Monitor the client's urine output closely.

Correct answer: B

Rationale: The correct answer is B: Prepare the client for emergency surgery. Aortic dissection is a life-threatening emergency that often necessitates immediate surgical intervention to prevent rupture and further complications. Administering antihypertensive medications (choice A) may be necessary but is not the priority over surgical intervention. While maintaining blood pressure with intravenous fluids (choice C) is important, the urgent need for surgery takes precedence. Monitoring urine output (choice D) is essential for assessing renal function but is not the priority in this critical situation.

5. Which of the following is the most likely indication for the use of immunosuppressant agents?

• A. Intractable seizure disorders
• B. Increased intracranial pressure
• C. Organ transplantation
• D. HIV/AIDS with multiple drug resistance

Correct answer: C

Rationale: The correct answer is C: Organ transplantation. Immunosuppressant agents are commonly used in organ transplant recipients to prevent organ rejection by suppressing the immune system. Choices A, B, and D are incorrect. Intractable seizure disorders are often managed with antiepileptic drugs, increased intracranial pressure is managed through various means like surgery and medications, and HIV/AIDS with multiple drug resistance is typically treated with antiretroviral therapy, not immunosuppressant agents.
