Nursing Elites

1. Claudication is a well-known effect of peripheral vascular disease. Which of the following facts about claudication is correct? Select the one that doesn't apply:

• A. It results when oxygen demand is greater than oxygen supply.
• B. It is characterized by pain that often occurs during rest.
• C. It is a result of tissue hypoxia.
• D. It is characterized by cramping and weakness.

Correct answer: D

Rationale: Claudication is a symptom of peripheral vascular disease where there is an inadequate supply of oxygen to the muscles due to reduced blood flow. This mismatch between oxygen demand and supply leads to tissue hypoxia, resulting in cramping, weakness, and discomfort. Option D correctly states that claudication is characterized by cramping and weakness, making it the correct answer. Options A, B, and C are incorrect. Claudication occurs when oxygen demand exceeds supply, not the other way around as stated in Option A. Pain in claudication typically occurs with activity, not at rest as mentioned in Option B. While tissue hypoxia is a consequence of claudication, it is not the primary cause, making Option C incorrect.

2. Based on the information given, which patient would be an appropriate candidate for a closed MRI without contrast?

• A. A 20-year-old woman with unexplained joint pain and a low BMI.
• B. A 35-year-old woman with Multiple Sclerosis who is trying to conceive.
• C. A 67-year-old man who had open-heart surgery 4 years ago.
• D. A 40-year-old woman in a hypomanic state for the last 2 days.

Correct answer: A

Rationale: The correct answer is the 20-year-old woman with unexplained joint pain and a low BMI. MRI can be used to diagnose musculoskeletal disorders, and this patient has no contraindications to an MRI. Choice B is incorrect because using MRI without contrast may not be ideal for a patient trying to conceive. Choice C is incorrect as the patient's past open-heart surgery may pose risks for an MRI without contrast. Choice D is incorrect since the patient's hypomanic state does not indicate a need for an MRI without contrast for joint pain.

3. A patient is undergoing a stress test on a treadmill and turns to talk to the nurse. Which of these statements would require the most immediate intervention?

• A. I'm feeling extremely thirsty and will get some water after this.
• B. I can feel my heart racing.
• C. My shoulder and arm are hurting.
• D. My blood pressure reading is 158/80

Correct answer: C

Rationale: The correct answer is 'C: My shoulder and arm are hurting.' Unilateral arm and shoulder pain are classic symptoms of myocardial ischemia, indicating possible heart issues. In this scenario, immediate intervention is required, and the stress test should be halted. Choice A about feeling thirsty does not indicate an acute medical issue. Choice B mentioning heart racing is expected during a stress test. Choice D, a blood pressure reading of 158/80, while slightly elevated, does not present an immediate concern compared to the symptoms of arm and shoulder pain suggesting cardiac distress.

4. Which laboratory test result should the nurse monitor to evaluate the effects of therapy for a 62-year-old female patient with acute pancreatitis?

• A. Calcium
• B. Bilirubin
• C. Amylase
• D. Potassium

Correct answer: C

Rationale: The correct answer is C: Amylase. In acute pancreatitis, amylase levels are typically elevated. Monitoring amylase levels helps assess the effectiveness of therapy in managing the condition. Elevated amylase is a key indicator of pancreatic inflammation. Calcium (Choice A) levels may be affected in pancreatitis, but they are not the primary indicator for evaluating therapy effectiveness. Bilirubin (Choice B) and Potassium (Choice D) levels may also be altered in pancreatitis, but they are not specific markers for monitoring therapy response in acute pancreatitis.

5. The nurse is caring for a patient who has recently had a successful catheter ablation. Which assessment finding demonstrates a successful outcome of this procedure?

• A. The patient is free of electrolyte imbalances
• B. The patient's WBC count is within normal limits
• C. The patient's EKG reading is regular
• D. The patient's urine output is 45 mL/hour

Correct answer: C

Rationale: A successful outcome of a catheter ablation procedure for arrhythmias, particularly SVT, is indicated by a regular EKG reading. Catheter ablation involves the use of radiofrequency energy to destroy the conduction fiber in the heart responsible for the arrhythmia. This destruction helps in preventing further episodes of arrhythmia. While choices A, B, and D are important assessments in patient care, they are not specific indicators of the success of a catheter ablation procedure. Electrolyte imbalances, WBC count, and urine output can be affected by various factors and are not directly related to the effectiveness of a catheter ablation in treating arrhythmias.
