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 involves compressing plaque against the wall of a diseased coronary artery to improve blood flow. It is a minimally invasive procedure performed during a cardiac catheterization to open blockages in the coronary arteries. Surgical repair of a diseased coronary artery refers to procedures like coronary artery bypass grafting (CABG), not PTCA. Placement of an automatic internal cardiac defibrillator is a different intervention used for managing cardiac arrhythmias, not for improving coronary blood flow. A non-invasive radiographic examination of the heart would typically refer to procedures like a cardiac CT scan or an MRI, not PTCA.

2. What is a priority problem for a child with severe edema caused by nephrotic syndrome?

• A. Risk for constipation
• B. Risk for skin breakdown
• C. Inability to regulate body temperature
• D. Consuming more calories or nutrients than the body requires

Correct answer: B

Rationale: In nephrotic syndrome, characterized by massive proteinuria, hypoalbuminemia, and edema, a child with severe edema is at high risk for skin breakdown. The priority concern is to prevent skin breakdown by cleaning skin surfaces and ensuring adequate separation with clothing to avoid irritation. The child with nephrotic syndrome is typically anorexic, making consuming more calories or nutrients than necessary not a concern. Risk for constipation and inability to regulate body temperature are not primary issues associated with edema caused by nephrotic syndrome.

3. A patient in the cardiac care unit is taking bumetanide (Bumex) for heart issues and is also diagnosed with Parkinson's Disease. An unlicensed assistive personnel is assisting with feeding the patient. Which of these foods should the nurse stress for the patient to eat most?

• A. Foods containing the least amount of salt
• B. Foods containing the most amount of potassium
• C. Foods containing the most amount of calories
• D. Foods containing the most amount of fiber

Correct answer: B

Rationale: Bumex is a loop diuretic that can lead to hypokalemia (low potassium levels). Hypokalemia can be dangerous and lead to various complications. To prevent a hypokalemic crisis, it is crucial to ensure an adequate intake of potassium. Therefore, the nurse should stress the patient to eat foods rich in potassium. Choices A, C, and D are not the priority in this situation. While monitoring salt intake is important in cardiac patients, the immediate concern with bumetanide use is the risk of hypokalemia, making choice B the most appropriate option.

4. Which oxygen delivery system would provide the highest concentrations of oxygen to the client?

• A. Venturi mask
• B. Partial rebreather mask
• C. Non-rebreather mask
• D. Simple face mask

Correct answer: C

Rationale: The correct answer is the non-rebreather mask. This oxygen delivery system has a one-way valve that prevents exhaled air from entering the reservoir bag and one or more valves covering the air holes on the face mask itself to prevent the inhalation of room air but allow exhalation of air. When a tight seal is achieved around the mask, up to 100% of oxygen is available. Choice A, the Venturi mask, delivers precise oxygen concentrations but not as high as the non-rebreather mask. Choice B, the partial rebreather mask, allows the client to rebreathe some exhaled air, resulting in lower oxygen concentrations than the non-rebreather mask. Choice D, the simple face mask, delivers low to moderate oxygen concentrations and is not designed to provide the highest concentrations like the non-rebreather mask.

5. Which clinical manifestations are recognized in nephrotic syndrome?

• A. Hematuria, bacteriuria, weight gain
• B. Gross hematuria, albuminuria, fever
• C. Hypertension, weight loss, proteinuria
• D. Massive proteinuria, hypoalbuminemia, edema

Correct answer: D

Rationale: Nephrotic syndrome is characterized by massive proteinuria, hypoalbuminemia, and edema. In this syndrome, there is loss of proteins, particularly albumin, in the urine leading to hypoalbuminemia, fluid retention, and subsequent edema. This results in elevated lipid levels like hypercholesterolemia, but not hypertension. Therefore, choices A, B, and C are incorrect. Hematuria, bacteriuria, fever, and weight loss are not typically associated with nephrotic syndrome, distinguishing it from other kidney disorders.
