1. When teaching a class about trisomy 21, the instructor would identify the cause of this disorder as:

• A. nondisjunction.
• B. X-linked recessive inheritance.
• C. genomic imprinting.
• D. autosomal dominant inheritance.

Correct answer: A

Rationale: The correct answer is A: nondisjunction. Trisomy 21, also known as Down syndrome, is caused by nondisjunction, which is an error in cell division leading to an extra copy of chromosome 21. This additional genetic material alters the course of development and causes the characteristics associated with Down syndrome. Choices B, C, and D are incorrect. X-linked recessive inheritance refers to genetic disorders carried on the X chromosome, genomic imprinting involves gene expression based on parental origin, and autosomal dominant inheritance relates to disorders caused by a dominant gene on one of the non-sex chromosomes. In the case of trisomy 21, the cause is specifically related to the error in chromosome division, making nondisjunction the most appropriate answer.

2. A 6-month-old infant is admitted with a diagnosis of respiratory syncytial virus (RSV). What should the nurse include in the care plan?

• A. Providing small, frequent feedings
• B. Administering antibiotics
• C. Maintaining strict isolation
• D. Elevating the head of the bed

Correct answer: D

Rationale: Elevating the head of the bed is essential in the care of an infant with RSV as it helps improve breathing by reducing congestion and promoting drainage. This position also aids in maintaining patent airways and can enhance comfort for the infant. Providing small, frequent feedings (Choice A) is generally appropriate for infants but is not a specific intervention for RSV. Administering antibiotics (Choice B) is not indicated for RSV, as it is a viral infection and antibiotics are ineffective against viruses. Maintaining strict isolation (Choice C) is important to prevent the spread of infections, but it is not a direct care intervention for managing RSV symptoms.

3. A child with a diagnosis of sickle cell anemia is admitted to the hospital with a vaso-occlusive crisis. What is the most important nursing intervention?

• A. Administering oxygen
• B. Administering pain medication
• C. Monitoring fluid intake
• D. Encouraging physical activity

Correct answer: B

Rationale: During a vaso-occlusive crisis in sickle cell anemia, the priority nursing intervention is administering pain medication. Pain management is crucial to alleviate the intense pain experienced by the child. While administering oxygen can help improve oxygenation, it is not the most critical intervention during a vaso-occlusive crisis. Monitoring fluid intake is important for overall care but is not the immediate priority during a crisis. Encouraging physical activity is contraindicated during a vaso-occlusive crisis as it can worsen the pain and the crisis itself.

4. .A nurse is caring for an infant whose vomiting is intractable. For what complication is it most important for the nurse to assess?

• A. Acidosis
• B. Alkalosis
• C. Hyperkalemia
• D. Hypernatremia

Correct answer: B

Rationale: Intractable vomiting can lead to alkalosis due to loss of stomach acids.

5. A parent brings an 18-month-old toddler to the clinic. The parent states, 'My child is so difficult to please, has temper tantrums, and annoys me by throwing food from the table.' What is the nurse’s best response?

• A. “Toddlers need discipline to prevent the development of antisocial behaviors.”
• B. “Toddlers are learning to assert independence, and this behavior is expected at this age.”
• C. “It is best to leave the toddler alone in the crib after calmly explaining why the behavior is unacceptable.”
• D. “This is the way a toddler expresses needs, and this behavior is acceptable during the initiative stage of development.”

Correct answer: B

Rationale: The correct answer is B: 'Toddlers are learning to assert independence, and this behavior is expected at this age.' At 18 months old, toddlers are in the stage of developing autonomy and testing boundaries. It is normal for them to exhibit behaviors such as temper tantrums and defiance as they explore their independence. Choice A is incorrect as discipline at this age is more about setting limits and providing guidance rather than preventing antisocial behaviors. Choice C is inappropriate as leaving a toddler alone in a crib after explaining unacceptable behavior is not a recommended approach for managing toddler behavior. Choice D is incorrect as the described behavior is typical of toddlers asserting independence, not related to the initiative stage of development. The best response involves acknowledging the child's developmental stage and understanding that these behaviors are part of their normal growth and development.
