1. 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.

2. 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.

3. After breastfeeding for 10 minutes at each breast, a new mother calls the nurse to the postpartum room to help change the newborn's diaper. As the mother begins the diaper change, the newborn spits up the breast milk. What action should the nurse implement first?

• A. Wipe away the spit-up and assist the mother with the diaper change.
• B. Sit the newborn upright and burp by rubbing or patting the upper back.
• C. Place the newborn in a position with the head lower than the feet.
• D. Turn the newborn to the side and use bulb suction for the mouth and nares.

Correct answer: B

Rationale: After a newborn spits up breast milk following feeding, the priority action for the nurse is to sit the newborn upright and burp by rubbing or patting the upper back. This position helps release trapped air and reduces the likelihood of further spit-up or aspiration. It is essential to address this first to prevent potential complications and ensure the newborn's comfort and safety.

4. A child with ADHD needs help with homework. What should the nurse encourage the parents to do?

• A. Encourage the parents to help the child with homework.
• B. Do the homework for the child.
• C. Set a regular homework schedule.
• D. Provide a quiet environment for homework.

Correct answer: A

Rationale: Encouraging parents to help the child with homework is the most appropriate course of action. By assisting the child, parents can provide necessary support and guidance without taking over the task entirely. This approach fosters independence and helps the child develop academic skills. Option B, doing the homework for the child, is counterproductive as it does not empower the child to learn and grow independently. Option C, setting a regular homework schedule, is important but does not address the immediate need for assistance. Option D, providing a quiet environment for homework, is helpful but does not directly involve parents in supporting the child's academic progress.

5. How can a nurse make a blind 8-year-old girl admitted to the hospital more comfortable?

• A. Bring familiar toys from home, such as a bear or doll.
• B. Explain the surroundings to the child.
• C. Allow the child to explore the room.
• D. Provide audio books and music.

Correct answer: A

Rationale: The correct answer is to bring familiar toys from home, such as a bear or doll. This action provides comfort and a sense of security for the child, as it allows her to have familiar objects around her in an unfamiliar environment, which can help reduce anxiety and stress during her hospital stay.
