Nursing Elites

1. Which of the following definitions best describes diverticulosis?

• A. An inflamed outpouching of the intestine
• B. A noninflamed outpouching of the intestine
• C. The partial impairment of the forward flow of intestinal contents
• D. An abnormal protrusion of an organ through the structure that usually holds it

Correct answer: B

Rationale: The correct answer is B: 'A noninflamed outpouching of the intestine.' Diverticulosis refers to the presence of small, bulging pouches (diverticula) that can form in the lining of the digestive system, especially the colon. These pouches are typically noninflamed. Choice A is incorrect because it describes diverticulitis, which is the inflammation of these pouches. Choice C is incorrect as it defines bowel obstruction, not diverticulosis. Choice D is incorrect as it refers to a hernia, not diverticulosis.

2. A client with liver dysfunction is having difficulty with protein metabolism. The nurse anticipates that the results of which of the following serum laboratory studies will be elevated?

• A. Lactic acid
• B. Ammonia
• C. Albumin
• D. Lactase

Correct answer: B

Rationale: During deamination of proteins, the liver splits the amino group from the carbon-containing compound, which results in the formation of ammonia and a carbon residue. The liver then converts the toxic ammonia substance into urea, which can be excreted by the kidneys. Clients with liver dysfunction may have high serum ammonia levels as a result.

3. 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.

4. A client is suspected of having hepatitis. Which diagnostic test results will assist in confirming this diagnosis?

• A. Decreased erythrocyte sedimentation rate
• B. Elevated serum bilirubin
• C. Elevated hemoglobin
• D. Elevated blood urea nitrogen

Correct answer: B

Rationale: Laboratory indicators of hepatitis include elevated liver enzyme levels, elevated serum bilirubin levels, elevated erythrocyte sedimentation rates, and leucopenia. An elevated blood urea nitrogen may indicate renal dysfunction. A hemoglobin level is unrelated to this diagnosis.

5. The nurse aspirates 40 mL of undigested formula from the client’s nasogastric tube. Before administering an intermittent tube feeding, the nurse understands that the 40 mL of gastric aspirate should be

• A. Discarded properly and recorded as output on the client’s intake and output record.
• B. Poured into the nasogastric tube through a syringe with the plunger removed.
• C. Mixed with the formula and poured into the nasogastric tube through a syringe with the plunger removed.
• D. Diluted with water and injected into the nasogastric tube by putting pressure on the plunger.

Correct answer: B

Rationale: After checking the residual feeding contents, the gastric contents are reinstalled into the stomach by removing the syringe bulb or plunger and pouring the gastric contents into the syringe and through the nasogastric tube. Gastric contents should be reinstalled to maintain the client’s electrolyte balance. The gastric contents should be poured into the nasogastric tube through a syringe without a plunger and not injected by putting pressure on the plunger. Gastric contents do not need to be mixed with water or should the contents be discarded.
