Nursing Elites

1. Which of the following laboratory results would be expected in a client with peritonitis?

• A. Partial thromboplastin time above 100 seconds
• B. Hemoglobin level below 10 mg/dL
• C. Potassium level above 5.5 mEq/L
• D. White blood cell count above 15,000

Correct answer: D

Rationale: A white blood cell count above 15,000 is indicative of an infection, such as peritonitis.

2. A client is providing instructions to a client who is scheduled for an oral cholecystogram. The nurse tells the client to

• A. Eat a fat-free meal on the evening before the procedure.
• B. Maintain strict NPO status on the day of the procedure.
• C. Avoid oral intake except for water on the day of the procedure.
• D. Eat a high-fat meal for breakfast on the day of the procedure.

Correct answer: C

Rationale: For an oral cholecystogram, the client should eat a fat-free meal the evening before the procedure and avoid oral intake except for water on the day of the procedure. During the test, the client may be given a high-fat meal or drink to stimulate gallbladder emptying. Choice A is incorrect because the client should have a fat-free meal, not a high-fat meal. Choice B is incorrect as strict NPO status is not required. Choice D is incorrect as a high-fat meal is not recommended for breakfast on the day of the procedure.

3. Your patient has a retractable gastric peptic ulcer and has had a gastric vagotomy. Which factor increases as a result of vagotomy?

• A. Peristalsis.
• B. Gastric acidity.
• C. Gastric motility.
• D. Gastric pH.

Correct answer: D

Rationale: After a gastric vagotomy, the gastric pH increases as a result of reduced acid secretion.

4. You promote hemodynamic stability in a patient with upper GI bleeding by:

• A. Encouraging oral fluid intake.
• B. Monitoring central venous pressure.
• C. Monitoring laboratory test results and vital signs.
• D. Giving blood, electrolyte and fluid replacement.

Correct answer: D

Rationale: Promoting hemodynamic stability in a patient with upper GI bleeding involves giving blood, electrolyte, and fluid replacement.

5. 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.
