Nursing Elites

1. The nurse is caring for a client with a serum potassium level of 3.5 mEq/L. The client is placed on a cardiac monitor and receives 40 mEq potassium chloride in 1000 ml of 5% dextrose in water IV. Which of the following EKG patterns indicates to the nurse that the infusions should be discontinued?

• A. Narrowed QRS complex
• B. Shortened "PR"? interval
• C. Tall peaked "T"? waves
• D. Prominent "U"? waves

Correct answer: C

Rationale: A tall peaked T wave is a characteristic EKG pattern associated with hyperkalemia. Hyperkalemia refers to high levels of potassium in the blood, which can lead to cardiac arrhythmias and other serious complications. Tall peaked T waves are a red flag for potential cardiac issues and can indicate the need to discontinue potassium infusions. The other choices, such as narrowed QRS complex, shortened "PR"? interval, and prominent "U"? waves, are not typically associated with hyperkalemia. Therefore, recognizing tall peaked T waves is crucial for the nurse to take prompt action in managing the client's condition.

2. The nurse is performing a neurological assessment on a client post right cerebrovascular accident. Which finding, if observed by the nurse, would warrant immediate attention?

• A. Decrease in level of consciousness
• B. Loss of bladder control
• C. Altered sensation to stimuli
• D. Emotional lability

Correct answer: A

Rationale: A decrease in the level of consciousness is a critical finding that would warrant immediate attention in a client post right cerebrovascular accident. This change may indicate an increase in intracranial pressure, leading to inadequate oxygenation of the brain. It could also reveal the presence of a transient ischemic attack, which may signal an impending thrombotic cerebrovascular accident. Loss of bladder control (choice B) can be managed and monitored but does not indicate an immediate threat to the client's life. Altered sensation to stimuli (choice C) can be a concerning finding but may not require immediate attention unless it affects the client's safety. Emotional lability (choice D) may be distressing for the client but does not pose an immediate risk to their health compared to a decrease in the level of consciousness.

3. 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.

4. When analyzing the results of the urinalysis collected preoperatively from a child with epispadias scheduled for surgical repair, which finding should the nurse most likely expect to note?

• A. Hematuria
• B. Proteinuria
• C. Bacteriuria
• D. Glucosuria

Correct answer: C

Rationale: Epispadias is a congenital defect characterized by the abnormal placement of the urethral orifice of the penis, often on the dorsum. This anatomical anomaly predisposes individuals to bacterial entry into the urinary tract, leading to bacteriuria. Hematuria, proteinuria, and glucosuria are not typically associated with epispadias. Hematuria refers to the presence of blood in the urine, proteinuria indicates protein in the urine, and glucosuria is the presence of glucose in the urine, none of which are commonly seen in epispadias.

5. During an assessment of a child admitted to the hospital with a probable diagnosis of nephrotic syndrome, what assessment findings should the nurse expect to observe? Select one that applies.

• A. Proteinuria
• B. Weight gain
• C. Decreased serum lipids
• D. Hematuria

Correct answer: A

Rationale: In nephrotic syndrome, the hallmark finding is massive proteinuria due to increased glomerular permeability. This leads to hypoalbuminemia, resulting in generalized edema. Weight gain, not weight loss, is typically seen due to fluid retention. Serum lipids are elevated, not decreased, in nephrotic syndrome. Hematuria, the presence of blood in the urine, is not a typical finding in nephrotic syndrome.
