Nursing Elites

1. A child is hospitalized because of persistent vomiting. The nurse should monitor the child closely for which problem?

• A. Diarrhea
• B. Metabolic acidosis
• C. Metabolic alkalosis
• D. Hyperactive bowel sounds

Correct answer: C

Rationale: In the scenario of persistent vomiting, the child is at risk of developing metabolic alkalosis due to the loss of hydrochloric acid. Vomiting leads to the loss of gastric acid, resulting in an imbalance that causes metabolic alkalosis. Metabolic acidosis is incorrect as it would occur in a child with diarrhea due to the loss of bicarbonate. While diarrhea can sometimes be associated with vomiting, in this case, the primary focus is on the effects of vomiting. Hyperactive bowel sounds are not typically associated with vomiting, making this choice less relevant to the situation described.

2. A physician suspects a patient may have pancreatitis. Which of the following tests would be most appropriate to diagnose this condition?

• A. CK and Troponin
• B. BUN and Creatinine
• C. Amylase and Lipase
• D. HDL and LDL Cholesterol Levels

Correct answer: C

Rationale: To diagnose pancreatitis, testing amylase and lipase levels is crucial. Amylase and lipase are enzymes produced by the pancreas that help digest carbohydrates and lipids. In pancreatitis, these enzymes are released in high amounts into the bloodstream due to pancreatic inflammation or damage. Elevated levels of amylase and lipase in blood tests strongly indicate pancreatitis. Choice A, CK and Troponin, are cardiac markers used in diagnosing heart conditions like myocardial infarction, not pancreatitis. Choice B, BUN and Creatinine, are kidney function tests, not specific to pancreatitis. Choice D, HDL and LDL Cholesterol Levels, are lipid profile tests used to assess cardiovascular health, not for diagnosing pancreatitis.

3. What is the cause of meningitis that is fatal in half of the infected patients?

• A. Virus
• B. Bacteria
• C. Fungus
• D. Noninfectious agent

Correct answer: B

Rationale: Bacterial meningitis is caused by bacterial pathogens such as Streptococcus pneumoniae, Haemophilus influenzae, Listeria monocytogenes, and Neisseria meningitidis. These bacteria commonly lead to acute onset meningitis, presenting with symptoms like fever, stiff neck, and altered consciousness. The statement that bacterial meningitis is fatal in about 50% of cases is accurate, making it a serious and life-threatening condition. Viruses can also cause meningitis, but they are not typically associated with the high fatality rate seen in bacterial meningitis. Fungal meningitis is less common and usually affects individuals with weakened immune systems. Noninfectious agents do not cause meningitis.

4. The client is being prepared for insertion of a pulmonary artery catheter (Swan-Ganz catheter). What information does the client need to know about the purpose of this catheter insertion?

• A. Stroke volume
• B. Cardiac output
• C. Venous pressure
• D. Left ventricular functioning

Correct answer: D

Rationale: The correct answer is D: Left ventricular functioning. The purpose of inserting a pulmonary artery catheter is to obtain information about left ventricular functioning when the catheter balloon is inflated. Choices A, B, and C are incorrect because while a pulmonary artery catheter can provide information on stroke volume, cardiac output, and venous pressure, its primary purpose is to assess left ventricular function.

5. Which goal has the highest priority in the plan of care for a 26-year-old homeless patient admitted with viral hepatitis who has severe anorexia and fatigue?

• A. Increase activity level.
• B. Maintain adequate nutrition
• C. Establish a stable environment
• D. Identify sources of hepatitis exposure

Correct answer: B

Rationale: The highest priority outcome is to maintain adequate nutrition because it is essential for hepatocyte regeneration. In viral hepatitis, the liver is affected, and proper nutrition supports the liver's function and regeneration. While increasing activity level and establishing a stable environment are important, they are not as urgent as ensuring the patient receives proper nutrition. Identifying sources of hepatitis exposure can help prevent future infections, but in the acute phase, the immediate focus should be on providing adequate nutrition to support the patient's recovery.
