Nursing Elites

1. A client is scheduled for a percutaneous transluminal coronary angioplasty (PTCA). The nurse knows that a PTCA is:

• A. Surgical repair of a diseased coronary artery
• B. Placement of an automatic internal cardiac defibrillator
• C. Procedure that compresses plaque against the wall of the diseased coronary artery to improve blood flow
• D. Non-invasive radiographic examination of the heart

Correct answer: C

Rationale: Percutaneous transluminal coronary angioplasty (PTCA) is a procedure that compresses plaque against the wall of the diseased coronary artery to improve blood flow. It is performed during a cardiac catheterization to improve coronary artery blood flow in a diseased artery. Surgical repair of a diseased coronary artery is typically done through procedures like aorto-coronary bypass graft (ACBG) rather than PTCA. Placement of an automatic internal cardiac defibrillator (AICD) is a different procedure used for managing cardiac arrhythmias. Non-invasive radiographic examination of the heart refers to procedures like echocardiography or cardiac MRI, not PTCA.

2. The nurse is writing out discharge instructions for the parents of a child diagnosed with celiac disease. The nurse should focus primarily on which aspect of care?

• A. Restricting activity
• B. Following a gluten-free diet
• C. Following a lactose-free diet
• D. Giving medication to manage the condition

Correct answer: B

Rationale: The primary nursing consideration in the care of a child with celiac disease is to instruct the child and parents about proper dietary management. The cornerstone of managing celiac disease is maintaining a strict gluten-free diet to prevent symptoms and long-term complications. While medications may be part of the treatment plan, dietary adjustments, particularly following a gluten-free diet, are crucial for managing the condition effectively. Restricting activity is not the primary focus of care for celiac disease. A lactose-free diet is not typically necessary unless the child also has lactose intolerance, which is distinct from celiac disease.

3. What is the most appropriate suggestion regarding the diet for an 18-month-old child experiencing mild diarrhea and 'mushy' stools, but tolerating fluids and solid foods?

• A. Applesauce, bananas, wheat toast
• B. Mashed potatoes with baked chicken
• C. Gelatin, strained cabbage, and custard
• D. Fluids only until the 'mushy' stools stop

Correct answer: B

Rationale: For a child with mild diarrhea who is tolerating fluids and solid foods, the most appropriate diet suggestion would be to continue feeding a normal diet to prevent dehydration, reduce stool frequency and volume, and hasten recovery. Foods that are well tolerated during diarrhea include bland but nutritional options like complex carbohydrates (rice, wheat, potatoes, cereals), yogurt with live cultures, cooked vegetables, and lean meats. Mashed potatoes with baked chicken provide a balance of nutrients and are easy on the digestive system. Options A and C contain foods that may worsen diarrhea; applesauce and gelatin can be high in sugars which can exacerbate diarrhea, and cabbage may be hard to digest for some individuals. Option D of offering fluids only can affect the child's nutritional status by not providing enough essential nutrients during the recovery period.

4. The nurse cares for a patient who has just had a thoracentesis. Which assessment information obtained by the nurse is a priority to communicate to the health care provider?

• A. Oxygen saturation is 88%.
• B. Blood pressure is 145/90 mm Hg.
• C. Respiratory rate is 22 breaths/minute when lying flat.
• D. Pain level is 5 (on a 0 to 10 scale) with a deep breath.

Correct answer: A

Rationale: The correct answer is 'Oxygen saturation is 88%.' Following a thoracentesis, oxygen saturation should improve. A saturation of 88% suggests a potential complication like pneumothorax. While the other assessment findings are important, the priority is to address the low oxygen saturation to prevent further complications. High blood pressure and respiratory rate may also need attention, but the immediate concern is the oxygen saturation level. Pain level, though significant for the patient's comfort, takes lower priority compared to the potential life-threatening issue of hypoxia.

5. Which of the following is NOT a warning sign that compensatory mechanisms in a patient in shock are failing?

• A. Increasing heart rate above normal for the patient's age.
• B. Absent peripheral pulses
• C. Decreasing level of consciousness
• D. Increasing blood pressure

Correct answer: D

Rationale: In a patient in shock, increasing blood pressure is not a sign that compensatory mechanisms are failing. As shock progresses and compensatory mechanisms fail, systolic blood pressure will decrease, leading to hypotension, which is a late and ominous sign in these patients. Therefore, choices A, B, and C are warning signs of failing compensatory mechanisms in shock: an increasing heart rate above normal, absent peripheral pulses, and decreasing level of consciousness, respectively. An increasing blood pressure is not indicative of compensatory failure in shock; instead, it may be a sign of compensatory mechanisms still trying to maintain perfusion pressure.
