Nursing Elites

1. What should be included in the teaching plan for parents of an infant diagnosed with phenylketonuria (PKU)?

• A. Mental retardation occurs if PKU is untreated.
• B. Testing for PKU is done immediately after birth.
• C. Treatment for PKU includes lifelong dietary management.
• D. PKU is transmitted by an autosomal recessive gene.

Correct answer: A

Rationale: The correct answer is A: 'Mental retardation occurs if PKU is untreated.' Phenylketonuria (PKU) is a metabolic disorder that, if left untreated with dietary management, can lead to severe mental retardation due to the accumulation of phenylalanine. It is crucial for parents to understand the potential consequences of untreated PKU to emphasize the importance of early and consistent treatment. Choice B is incorrect because testing for PKU is typically done through newborn screening shortly after birth, not immediately. Choice C is incorrect as treatment for PKU primarily involves strict dietary management that restricts phenylalanine intake, not lifelong medications. Choice D is incorrect as PKU is inherited in an autosomal recessive pattern, meaning that both parents must pass on a mutated gene for the disorder to manifest.

2. A premature infant with respiratory distress syndrome (RDS) receives artificial surfactant. How does the nurse explain surfactant therapy to the parents?

• A. Surfactant improves the ability of your baby’s lungs to exchange oxygen and carbon dioxide.
• B. The drug prevents your baby from requiring excessive sedation.
• C. Surfactant is used to reduce episodes of periodic apnea.
• D. Your baby needs this medication to combat a potential respiratory tract infection.

Correct answer: A

Rationale: The correct answer is A. Surfactant therapy is explained to parents as a treatment that enhances the lungs' ability to exchange oxygen and carbon dioxide. This is essential for premature infants with respiratory distress syndrome (RDS) as it helps improve their respiratory function. Choices B, C, and D are incorrect because surfactant therapy primarily focuses on addressing lung function and is not related to sedation, apnea reduction, or fighting respiratory tract infections.

3. A child is admitted with extensive burns. The nurse notes burns on the child’s lips and singed nasal hairs. The nurse should suspect that the child has a(n)

• A. chemical burn
• B. inhalation injury
• C. electrical burn
• D. hot-water scald

Correct answer: B

Rationale: Burns on the lips and singed nasal hairs are indicative of an inhalation injury. This suggests that the child has likely inhaled hot gases or smoke, leading to damage in the respiratory tract. Choice A, chemical burn, is incorrect because the symptoms described are more aligned with inhalation rather than direct contact with chemicals. Choice C, electrical burn, is incorrect as there are no mentions of contact with an electrical source. Choice D, hot-water scald, is also incorrect as the presentation of burns on the lips and singed nasal hairs is not characteristic of scald injuries.

4. The nurse is developing a teaching plan for a child who is to have his cast removed. What instruction would the nurse most likely include?

• A. Applying petroleum jelly to the dry skin.
• B. Rubbing the skin vigorously to remove the dead skin.
• C. Soaking the area in warm water every day.
• D. Washing the skin with diluted peroxide and water.

Correct answer: C

Rationale: The correct instruction for the nurse to include in the teaching plan is to advise the child to soak the area in warm water every day. Soaking the area in warm water helps to gently remove dead skin without causing irritation, facilitating the safe and comfortable removal of the cast. Applying petroleum jelly (Choice A) may not be necessary and could interfere with the cast removal process. Rubbing the skin vigorously (Choice B) can lead to skin damage and should be avoided. Washing the skin with diluted peroxide and water (Choice D) is not recommended as peroxide can be irritating to the skin and may not aid in cast removal.

5. The instructor is educating a group of students about myelination in a child. Which statement by the students indicates that the teaching was successful?

• A. Myelination continues into adolescence.
• B. The process occurs in a head-to-toe fashion.
• C. Myelination speeds up nerve impulses.
• D. Myelination increases the specificity and efficiency of nerve impulses.

Correct answer: B

Rationale: The correct answer is B. Myelination occurs in a cephalocaudal (head-to-toe) pattern, improving nerve function progressively. Choice A is incorrect because myelination continues beyond 4 years of age and into adolescence. Choice C is incorrect as myelination speeds up nerve impulses rather than slowing them down. Choice D is incorrect because myelination increases the specificity and efficiency of nerve impulses, making them more focused and precise.
