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. Based on the information given, which patient would be an appropriate candidate for a closed MRI without contrast?

• A. A 20-year-old woman with unexplained joint pain and a low BMI.
• B. A 35-year-old woman with Multiple Sclerosis who is trying to conceive.
• C. A 67-year-old man who had open-heart surgery 4 years ago.
• D. A 40-year-old woman in a hypomanic state for the last 2 days.

Correct answer: A

Rationale: The correct answer is the 20-year-old woman with unexplained joint pain and a low BMI. MRI can be used to diagnose musculoskeletal disorders, and this patient has no contraindications to an MRI. Choice B is incorrect because using MRI without contrast may not be ideal for a patient trying to conceive. Choice C is incorrect as the patient's past open-heart surgery may pose risks for an MRI without contrast. Choice D is incorrect since the patient's hypomanic state does not indicate a need for an MRI without contrast for joint pain.

3. The nurse is caring for a 10-year-old on admission to the burn unit. One assessment parameter that will indicate that the child has adequate fluid replacement is:

• A. Urinary output of 30 ml per hour
• B. No complaints of thirst
• C. Increased hematocrit
• D. Good skin turgor around burn

Correct answer: A

Rationale: For a child of this age, this is adequate output, yet does not suggest overload. Disruption of sodium-ATPase activity presumably causes an intracellular sodium shift which contributes to hypovolemia and cellular edema. Heat injury also initiates the release of inflammatory and vasoactive mediators. These mediators are responsible for local vasoconstriction, systemic vasodilation, and increased transcapillary permeability. Increase in transcapillary permeability results in a rapid transfer of water, inorganic solutes, and plasma proteins between the intravascular and interstitial spaces.

4. After surgery for an imperforate anus, an infant returns with a red and edematous colostomy stoma. What action should the nurse take based on this finding?

• A. Elevate the buttocks.
• B. Document the findings.
• C. Apply ice immediately.
• D. Call the primary health care provider.

Correct answer: B

Rationale: A red and edematous colostomy stoma is a common finding immediately after surgery, and these changes are expected to decrease over time. As the stoma heals, it usually becomes pink without signs of abnormal drainage, swelling, or skin breakdown. Therefore, the appropriate action for the nurse is to document these normal findings. Elevating the buttocks, applying ice, or calling the primary health care provider are unnecessary interventions at this stage.

5. The healthcare professional is taking the health history of a patient being treated for sickle cell disease. After being told the patient has severe generalized pain, the healthcare professional expects to note which assessment finding?

• A. Severe and persistent diarrhea
• B. Intense pain in the toe
• C. Yellow-tinged sclera
• D. Headache

Correct answer: C

Rationale: In patients with sickle cell disease, severe generalized pain can be associated with vaso-occlusive crises, but yellow-tinged sclera is a common clinical finding related to sickle cell disease. This yellowing of the sclera, known as jaundice, occurs due to the release of bilirubin from damaged or destroyed red blood cells. Severe and persistent diarrhea is not a typical assessment finding in sickle cell disease. Intense pain in the toe may be associated with vaso-occlusive crisis but is not the expected assessment finding in this scenario. Headache is a common symptom in many conditions but is not specifically related to the assessment finding expected in a patient with sickle cell disease presenting with severe generalized pain.
