Nursing Elites

1. 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.

2. The nurse is caring for a client with a serum potassium level of 3.5 mEq/L. The client is placed on a cardiac monitor and receives 40 mEq potassium chloride in 1000 ml of 5% dextrose in water IV. Which of the following EKG patterns indicates to the nurse that the infusions should be discontinued?

• A. Narrowed QRS complex
• B. Shortened "PR"? interval
• C. Tall peaked "T"? waves
• D. Prominent "U"? waves

Correct answer: C

Rationale: A tall peaked T wave is a characteristic EKG pattern associated with hyperkalemia. Hyperkalemia refers to high levels of potassium in the blood, which can lead to cardiac arrhythmias and other serious complications. Tall peaked T waves are a red flag for potential cardiac issues and can indicate the need to discontinue potassium infusions. The other choices, such as narrowed QRS complex, shortened "PR"? interval, and prominent "U"? waves, are not typically associated with hyperkalemia. Therefore, recognizing tall peaked T waves is crucial for the nurse to take prompt action in managing the client's condition.

3. A healthcare professional is reviewing a patient's chart and notices that the patient suffers from Lyme disease. Which of the following microorganisms is related to this condition?

• A. Borrelia burgdorferi
• B. Streptococcus pyogenes
• C. Bacillus anthracis
• D. Enterococcus faecalis

Correct answer: A

Rationale: Lyme disease, the most common vector-borne disease in the United States, is caused by the bacterium Borrelia burgdorferi. Borrelia burgdorferi is transmitted to humans through the bite of infected black-legged ticks. Streptococcus pyogenes is associated with strep throat and other infections, not Lyme disease. Bacillus anthracis causes anthrax, a separate infectious disease. Enterococcus faecalis is more commonly linked to urinary tract infections and other healthcare-associated infections, not Lyme disease.

4. Which response by the nurse best explains the purpose of ranitidine (Zantac) for a patient admitted with bleeding esophageal varices?

• A. The medication will reduce the risk of aspiration.
• B. The medication will inhibit the development of gastric ulcers.
• C. The medication will prevent irritation of the enlarged veins.
• D. The medication will decrease nausea and improve appetite.

Correct answer: C

Rationale: The correct answer is: 'The medication will prevent irritation of the enlarged veins.' Esophageal varices are dilated submucosal veins. The therapeutic action of H2-receptor blockers in patients with esophageal varices is to prevent irritation and bleeding from the varices caused by reflux of acidic gastric contents. While ranitidine can decrease the risk of peptic ulcers, reduce nausea, and help prevent aspiration pneumonia, the primary purpose of H2-receptor blockade in this patient is to prevent irritation and bleeding from the varices, not the other listed effects.

5. A 55-year-old patient admitted with an abrupt onset of jaundice and nausea has abnormal liver function studies, but serologic testing is negative for viral causes of hepatitis. Which question by the nurse is most appropriate?

• A. Is there any history of IV drug use?
• B. Do you use any over-the-counter drugs?
• C. Are you taking corticosteroids for any reason?
• D. Have you recently traveled to a foreign country?

Correct answer: B

Rationale: The most appropriate question for the nurse to ask in this scenario is whether the patient uses any over-the-counter drugs. The patient's symptoms, negative serologic testing for viral hepatitis, and sudden onset of symptoms point towards toxic hepatitis, which can be triggered by commonly used over-the-counter medications like acetaminophen (Tylenol). Asking about IV drug use is relevant for viral hepatitis, not toxic hepatitis. Inquiring about recent travel to a foreign country is more pertinent to potential exposure to infectious agents causing viral hepatitis. Corticosteroid use is not typically associated with the symptoms described in the case.
