Nursing Elites

1. A nurse is reviewing the results of serum laboratory studies drawn on a client who is suspected of having hepatitis. The nurse interprets that an elevation in which of the following studies is the most specific indicator of the disease?

• A. Erythrocyte sedimentation rate
• B. Serum bilirubin
• C. Hemoglobin
• D. Blood urea nitrogen

Correct answer: C

Rationale: Laboratory indicators of hepatitis include elevated liver enzymes, serum bilirubin level, and erythrocyte sedimentation rate is nonspecific test that indicates the presence of inflammation somewhere in the body. Elevated blood urea nitrogen may indicate renal dysfunction. A hemoglobin level is unrelated to this diagnosis.

2. The nurse is planning to teach the client with gastroesophageal reflux disease about substances that will increase the lower esophageal sphincter pressure. Which of the following items would the nurse include on this list?

• A. Fatty foods
• B. Nonfat milk
• C. Chocolate
• D. Coffee

Correct answer: B

Rationale: Foods that increase the lower esophageal sphincter (LES) pressure will decrease reflux, and lessen the symptoms of gastroesophageal reflux disease (GERD). The food substance that will increase the LES pressure is nonfat milk. The other substances listed decrease the LES pressure, thus increasing reflux symptoms. Aggravating substances include chocolate, coffee, fatty foods and alcohol.

3. Michael, a 42 y.o. man is admitted to the med-surg floor with a diagnosis of acute pancreatitis. His BP is 136/76, pulse 96, Resps 22 and temp 101. His past history includes hyperlipidemia and alcohol abuse. The doctor prescribes an NG tube. Before inserting the tube, you explain the purpose to patient. Which of the following is a most accurate explanation?

• A. It empties the stomach of fluids and gas.
• B. It prevents spasms at the sphincter of Oddi.
• C. It prevents air from forming in the small intestine and large intestine.
• D. It removes bile from the gallbladder.

Correct answer: A

Rationale: Explain to the patient that the NG tube is used to empty the stomach of fluids and gas, which helps relieve symptoms of acute pancreatitis.

4. The nurse is scheduling diagnostic tests for a client. If all of the following diagnostic tests are ordered, which would be performed last?

• A. Gallbladder series
• B. Barium enema
• C. Barium swallow
• D. Oral cholecystogram

Correct answer: C

Rationale: The correct answer is C, 'Barium swallow.' A barium swallow should be done after a barium enema or gallbladder series to prevent the contrast used in the barium swallow from obstructing the view of other organs. It takes several days for swallowed barium to pass completely out of the gastrointestinal tract. Choices A, B, and D are incorrect because a barium swallow should be the last test performed to ensure clear imaging without interference from residual contrast material.

5. Which of the following factors is believed to be linked to Crohn’s disease?

• A. Constipation
• B. Diet
• C. Hereditary
• D. Lack of exercise

Correct answer: C

Rationale: Crohn's disease is believed to have a hereditary link, with genetic factors playing a significant role in its development.
