Nursing Elites

1. 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.

2. A patient in the cardiac care unit is taking bumetanide (Bumex) for heart issues and is also diagnosed with Parkinson's Disease. An unlicensed assistive personnel is assisting with feeding the patient. Which of these foods should the nurse stress for the patient to eat most?

• A. Foods containing the least amount of salt
• B. Foods containing the most amount of potassium
• C. Foods containing the most amount of calories
• D. Foods containing the most amount of fiber

Correct answer: B

Rationale: Bumex is a loop diuretic that can lead to hypokalemia (low potassium levels). Hypokalemia can be dangerous and lead to various complications. To prevent a hypokalemic crisis, it is crucial to ensure an adequate intake of potassium. Therefore, the nurse should stress the patient to eat foods rich in potassium. Choices A, C, and D are not the priority in this situation. While monitoring salt intake is important in cardiac patients, the immediate concern with bumetanide use is the risk of hypokalemia, making choice B the most appropriate option.

3. 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.

4. The nurse palpates the posterior chest while the patient says 99 and notes absent fremitus. What action should the nurse take next?

• A. Auscultate anterior and posterior breath sounds bilaterally
• B. Encourage the patient to turn, cough, and deep breathe
• C. Review the chest x-ray report for evidence of pneumonia
• D. Palpate the anterior chest and observe for barrel chest

Correct answer: A

Rationale: To assess for tactile fremitus, the nurse should use the palms of the hands to assess for vibration when the patient repeats a word or phrase such as '99'. After noting absent fremitus, the nurse should then auscultate the lungs to assess for the presence or absence of breath sounds. Absent fremitus may be noted with conditions like pneumothorax or atelectasis. The vibration is increased in conditions such as pneumonia, lung tumors, thick bronchial secretions, and pleural effusion. Encouraging the patient to turn, cough, and deep breathe is an appropriate intervention for atelectasis, but assessing breath sounds takes priority. Fremitus is decreased if the hand is farther from the lung or the lung is hyperinflated (barrel chest). Palpating the anterior chest for fremitus is less effective due to the presence of large muscles and breast tissue, making auscultation a more appropriate next step.

5. 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.
