Nursing Elites

1. In a 45-year-old woman with a history of arthritis experiencing severe heartburn and indigestion refractory to antacids, which findings on an esophageal manometry study are consistent with her diagnosis?

• A. Vigorous peristalsis and elevated lower esophageal sphincter (LES) pressure
• B. Absent peristalsis and elevated LES pressure
• C. Absent peristalsis and decreased LES pressure
• D. Vigorous peristalsis and decreased LES pressure

Correct answer: C

Rationale: The correct answer is C: Absent peristalsis and decreased lower esophageal sphincter (LES) pressure. The patient in this scenario has scleroderma esophagus, characterized by atrophy of esophageal smooth muscle, leading to the loss of peristalsis and LES tone. These changes contribute to severe symptoms of gastroesophageal reflux disease (GERD) and esophagitis. Absent peristalsis and decreased LES pressure are typical findings in scleroderma esophagus, contributing to the refractory nature of the patient's symptoms despite antacid use.

2. A client's telemetry monitor indicates the sudden onset of ventricular fibrillation. Which assessment finding should the nurse anticipate?

• A. Bounding erratic pulse.
• B. Regularly irregular pulse.
• C. Thready irregular pulse.
• D. No palpable pulse.

Correct answer: D

Rationale: Ventricular fibrillation is a life-threatening arrhythmia characterized by chaotic, asynchronous contractions of the ventricles, resulting in ineffective cardiac output. This leads to the absence of a palpable pulse. Nurses should be prepared to initiate immediate interventions such as defibrillation to restore normal cardiac rhythm in a client experiencing ventricular fibrillation.

3. A client with chronic renal failure is scheduled to receive epoetin alfa (Epogen). Which laboratory result should the nurse review before administering the medication?

• A. Blood urea nitrogen (BUN)
• B. Creatinine clearance
• C. Hemoglobin level
• D. Serum potassium

Correct answer: C

Rationale: The correct answer is to review the hemoglobin level before administering epoetin alfa (Epogen) to assess its effectiveness in stimulating red blood cell production. Hemoglobin level is a crucial indicator to monitor in clients with chronic renal failure receiving this medication. Choice A (Blood urea nitrogen) and Choice B (Creatinine clearance) are commonly monitored in renal failure but are not specifically relevant to assessing the effectiveness of epoetin alfa. Choice D (Serum potassium) is important to monitor due to potential imbalances in renal failure, but it is not directly related to evaluating the effectiveness of epoetin alfa.

4. A 70-year-old man presents with weight loss, jaundice, and a palpable mass in the right upper quadrant. Laboratory tests reveal elevated bilirubin and alkaline phosphatase levels. What is the most likely diagnosis?

• A. Gallstones
• B. Hepatitis
• C. Pancreatic cancer
• D. Primary biliary cirrhosis

Correct answer: C

Rationale: The presentation of a 70-year-old man with weight loss, jaundice, a palpable mass in the right upper quadrant, and elevated bilirubin and alkaline phosphatase levels is highly suggestive of pancreatic cancer. This clinical scenario, known as Courvoisier's sign, points towards a pancreatic malignancy due to biliary obstruction. Gallstones could cause similar symptoms but would typically not present with a palpable mass. Hepatitis usually does not present with a palpable mass and would have different laboratory findings. Primary biliary cirrhosis typically presents differently with chronic cholestasis without the presence of a palpable mass or a pancreatic lesion.

5. A client with heart failure is receiving intravenous furosemide (Lasix). Which assessment finding indicates that the medication is having the desired effect?

• A. Decreased peripheral edema.
• B. Elevated blood pressure.
• C. Increased heart rate.
• D. Decreased urine output.

Correct answer: A

Rationale: The correct answer is A: 'Decreased peripheral edema.' In a client with heart failure receiving furosemide, decreased peripheral edema indicates that the medication is effectively reducing fluid overload. Furosemide is a diuretic that helps the body eliminate excess fluid and salt through increased urine output, leading to a reduction in peripheral edema, which is a common symptom of heart failure. Monitoring and recognizing this improvement in edema are crucial in managing heart failure effectively.
