Nursing Elites

1. A mother calls the school nurse to report that her preschool-aged child was bitten by a tick during a school outing last week. The mother removed the tick and flushed it down the toilet. What action should the school nurse take?

• A. Refer the mother to the Centers for Disease Control and Prevention.
• B. Report the incident to the school principal.
• C. Culture the bite site when the child returns to school.
• D. Schedule a test for Lyme disease if a rash appears.

Correct answer: D

Rationale: The correct action to take in this situation is to schedule a test for Lyme disease if a rash appears. Lyme disease can be transmitted through tick bites, and a rash is a common early symptom of the disease. Testing for Lyme disease is crucial for timely diagnosis and treatment to prevent complications. Referring the mother to the Centers for Disease Control and Prevention (Choice A) is not necessary at this point, as immediate testing for Lyme disease is more appropriate. Reporting the incident to the school principal (Choice B) is not the most direct action to address the potential health concern. Culturing the bite site when the child returns to school (Choice C) may not be as effective as scheduling a test for Lyme disease if a rash appears, as the latter is a more specific diagnostic measure for Lyme disease.

2. A male infant with a 2-day history of fever and diarrhea is brought to the clinic by his mother, who tells the nurse that the child refuses to drink anything. The nurse determines that the child has a weak cry with no tears. Which intervention is most important to implement?

• A. Provide a bottle of electrolyte solution.
• B. Infuse normal saline intravenously.
• C. Administer an antipyretic rectally.
• D. Apply an external cooling blanket.

Correct answer: B

Rationale: Infusing normal saline intravenously is crucial to treat dehydration caused by fever and diarrhea. In this scenario, the infant's weak cry with no tears indicates severe dehydration, necessitating rapid fluid replacement via intravenous normal saline to restore fluid balance and prevent complications.

3. A 4-week-old premature infant has been receiving epoetin alfa (Epogen) for the last three weeks. Which assessment finding indicates to the healthcare provider that the drug is effective?

• A. Slowly increasing urinary output over the last week.
• B. Respiratory rate changes from the 40s to the 60s.
• C. Changes in apical heart rate from the 180s to the 140s.
• D. Change in indirect bilirubin from 12 mg/dl to 8 mg/dl.

Correct answer: C

Rationale: The correct answer is C. Epoetin alfa stimulates erythropoiesis, leading to an increase in red blood cell production and improving oxygen-carrying capacity. As the oxygenation status improves, there is a reduction in heart rate. Therefore, changes in apical heart rate from the 180s to the 140s indicate that the drug is effective. Choices A, B, and D are incorrect because they do not directly reflect the expected outcome of epoetin alfa therapy. Increasing urinary output, changes in respiratory rate, and decreasing bilirubin levels are not primary indicators of the drug's effectiveness in this context.

4. In which chromosome pattern is Duchenne disease inherited?

• A. Autosomal dominant
• B. Autosomal recessive
• C. X-linked recessive
• D. Mitochondrial

Correct answer: C

Rationale: Duchenne disease is caused by a mutation in the DMD gene located on the X chromosome, leading to an X-linked recessive inheritance pattern. Males are typically affected by this disorder as they have only one X chromosome, while females are carriers with one normal and one affected X chromosome.

5. What maternal behavior is typically observed when a new mother first receives her infant?

• A. She eagerly reaches for the infant, undresses the infant, and examines the infant completely.
• B. Her arms and hands receive the infant and she then traces the infant's profile with her fingertips.
• C. Her arms and hands receive the infant and she then cuddles the infant to her own body.
• D. She eagerly reaches for the infant and then holds the infant close to her own body.

Correct answer: B

Rationale: When a new mother first receives her infant, a typical maternal behavior is to use her arms and hands to receive the infant and then trace the infant's profile with her fingertips. This action is a gentle way of bonding with the newborn and aids in recognizing the infant's features. Choices A, C, and D are incorrect as they do not accurately describe the common behavior of tracing the infant's profile, which is a significant part of the initial interaction between a mother and her newborn.
