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 child with a diagnosis of gastroesophageal reflux disease (GERD) is being discharged. What dietary instructions should the nurse provide?

• A. Avoid spicy foods
• B. Avoid gluten
• C. Avoid high-fat foods
• D. Avoid dairy products

Correct answer: B

Rationale: The correct dietary instruction for a child with GERD is to avoid gluten. Gluten is a protein found in wheat, barley, and rye, and it can exacerbate GERD symptoms in some individuals. Avoiding gluten can help reduce inflammation and irritation in the gastrointestinal tract, thereby alleviating symptoms of GERD. Choices A, C, and D are incorrect because while spicy foods, high-fat foods, and dairy products can trigger GERD symptoms in some individuals, avoiding gluten specifically is more relevant for managing GERD.

3. A 7-year-old child has an altered mental status, high fever, and a generalized rash. You perform your assessment and initiate oxygen therapy. En route to the hospital, you should be most alert for

• A. vomiting
• B. seizures
• C. combativeness
• D. respiratory distress

Correct answer: B

Rationale: Seizures are a common complication in children with high fever and altered mental status, indicating a risk of febrile seizures. While vomiting can occur with altered mental status, seizures are of higher concern due to the association with febrile illnesses in children. Combativeness may be a concern in some altered mental status cases but is not as common as seizures. Respiratory distress, although important, is not the primary concern in this scenario given the symptoms presented.

4. When assessing a child with a possible fracture, what would be the most reliable indicator for the nurse to identify?

• A. Lack of spontaneous movement
• B. Point tenderness
• C. Bruising
• D. Inability to bear weight

Correct answer: B

Rationale: Point tenderness is the most reliable indicator of a possible fracture in a child. It refers to localized pain at a specific point, indicating a potential bone injury. Lack of spontaneous movement (Choice A) is non-specific and can be due to various reasons. Bruising (Choice C) may be present in fractures but is not as specific as point tenderness. Inability to bear weight (Choice D) can also be seen in fractures but may not always be present, making it less reliable compared to point tenderness.

5. When caring for a child and family who just moved out of a dangerous neighborhood, which of the following approaches is appropriate to the family stress theory?

• A. Determining who the decision maker is
• B. Assessing the child's coping abilities
• C. Finding out how siblings feel
• D. Explaining procedures to siblings

Correct answer: B

Rationale: Assessing the child's coping abilities is appropriate when applying the family stress theory because it helps understand how well the child is managing the stress of the situation. This assessment can provide insights into the child's emotional well-being and resilience, enabling healthcare providers to offer appropriate support. Choices A, C, and D are less relevant in the context of family stress theory. Determining who the decision-maker is may be important but is not directly related to assessing the child's coping abilities. Finding out how siblings feel and explaining procedures to siblings may be valuable aspects of care but are not specifically aligned with the core principles of the family stress theory, which focus on understanding and addressing stress within the family unit.
