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. Rhogam is most often used to treat____ mothers that have a ____ infant.

• A. RH positive, RH positive
• B. RH positive, RH negative
• C. RH negative, RH positive
• D. RH negative, RH negative

Correct answer: C

Rationale: Rhogam is administered to RH-negative mothers who have an RH-positive infant to prevent the development of anti-RH antibodies in the mother's system. Choice A (RH positive, RH positive) is incorrect because Rhogam is not used when both mother and infant are RH positive. Choice B (RH positive, RH negative) is incorrect because Rhogam is used when the mother is RH negative, not RH positive. Choice D (RH negative, RH negative) is incorrect as Rhogam is not typically needed if both mother and infant are RH negative.

3. After an unimmunized individual is exposed to hepatitis B through a needle-stick injury, which actions will the nurse plan to take (select one that does not apply)?

• A. Administer hepatitis B vaccine.
• B. Test for antibodies to hepatitis B.
• C. Teach about alpha-interferon therapy.
• D. Give hepatitis B immune globulin.

Correct answer: C

Rationale: In the case of exposure to hepatitis B, the nurse should plan to administer hepatitis B vaccine to provide active immunity. Testing for antibodies to hepatitis B is essential to determine the individual's immune status. Giving hepatitis B immune globulin is necessary for passive immunity in cases of exposure. However, teaching about alpha-interferon therapy is not part of the standard management for hepatitis B exposure. Interferon therapy and oral antivirals are typically used in the treatment of chronic hepatitis B infections, not for prophylaxis after exposure.

4. A nurse is caring for a 2-day-old infant who has a bilirubin level of 19 mg/dl. The physician has ordered phototherapy. Which of the following actions indicates correct preparation of the infant for this procedure?

• A. Undress the baby down to a diaper and hat
• B. Place the baby in his mother's arms before turning on the light
• C. Position the phototherapy light approximately 3 inches above the baby's skin
• D. Secure eye protection for the infant without occluding the nose

Correct answer: D

Rationale: Phototherapy is used to treat high levels of bilirubin among infants, typically evidenced as jaundice. The nurse must position the infant carefully during this procedure to maximize the benefits of the light therapy while protecting the baby. Placing protective eyewear over the baby's eyes without covering the nose is crucial to shield the eyes from the ultraviolet light. Undressing the baby down to a diaper and hat (Choice A) is a standard practice to maximize skin exposure to the phototherapy light. Placing the baby in his mother's arms before turning on the light (Choice B) is not necessary for the preparation of the infant for phototherapy. Positioning the phototherapy light approximately 3 inches above the baby's skin (Choice C) is incorrect as the distance should be as recommended by the healthcare provider based on the manufacturer's instructions.

5. The nurse prepares a patient with a left-sided pleural effusion for a thoracentesis. How should the nurse position the patient?

• A. Supine with the head of the bed elevated 30 degrees
• B. In a high-Fowler's position with the left arm extended
• C. On the right side with the left arm extended above the head
• D. Sitting upright with the arms supported on an overbed table

Correct answer: D

Rationale: The correct position for a patient with a left-sided pleural effusion undergoing thoracentesis is sitting upright with the arms supported on an overbed table. This position helps increase lung expansion, allows fluid to collect at the lung bases, and expands the intercostal space making access to the pleural space easier. Placing the patient supine, in a high-Fowler's position, or on the right side with the left arm extended above the head could increase the work of breathing for the patient and complicate the thoracentesis procedure for the healthcare provider.
