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. What is the priority nursing responsibility when a 3-year-old child in a crib is experiencing a tonic-clonic seizure with a clamped jaw?

• A. Apply restraints.
• B. Administer oxygen.
• C. Protect the child from self-injury.
• D. Insert a plastic airway in the child’s mouth.

Correct answer: C

Rationale: During a tonic-clonic seizure, the priority nursing responsibility is to protect the child from self-injury. Applying restraints (Choice A) can cause harm by restricting movement during the seizure. While administering oxygen (Choice B) may be necessary, it is not the immediate priority during an active seizure. Inserting a plastic airway (Choice D) is contraindicated as it can lead to injury and is not recommended during a seizure. Protecting the child from self-injury (Choice C) is crucial to prevent harm from uncontrolled movements and potential falls, ensuring the safety of the child.

3. A 13-year-old girl tells the nurse at the pediatric clinic that she took a pregnancy test and it was positive. She adds that her grandfather, with whom she, her younger sisters, and her mother live, has repeatedly molested her for the past 3 years. When the nurse asks the girl if she has told this to anyone, she replies, 'Yes, but my mother doesn’t believe me.' Legally, who should the nurse notify?

• A. Police regarding a potential sex crime
• B. Health care provider to confirm the pregnancy
• C. Child Protective Services for immediate intervention
• D. The girl’s mother about the positive pregnancy test result

Correct answer: C

Rationale: In cases of child abuse and ongoing molestation, as described in the scenario, the primary concern is the safety and well-being of the child. Child Protective Services should be notified immediately for intervention to protect the girl and other children in the household from further harm. The police may be involved later to investigate the criminal aspect of the abuse. Notifying the healthcare provider solely to confirm the pregnancy or informing the girl’s mother about the positive test result does not address the urgent need for intervention and protection from abuse. Child Protective Services are trained to handle such cases and provide the necessary support and protection for the child and other vulnerable individuals in the family. Immediate action is crucial to ensure the girl's safety and prevent further harm.

4. The healthcare provider notes that a child has lost 8 pounds after 4 days of hospitalization for acute glomerulonephritis. This is most likely the result of

• A. poor appetite
• B. increased potassium intake
• C. reduction of edema
• D. restriction to bed rest

Correct answer: C

Rationale: In acute glomerulonephritis, weight loss is most likely due to the reduction of edema. Edema is a common symptom of glomerulonephritis, which causes fluid retention and swelling in the body. As treatment progresses and the condition improves, the reduction of edema leads to weight loss. Choices A, B, and D are incorrect as they do not directly address the underlying pathophysiology of acute glomerulonephritis and its impact on weight loss.

5. What factor predisposes the urinary tract to infection in children?

• A. increased fluid intake
• B. short urethra in young girls
• C. prostatic secretions in males
• D. frequent emptying of the bladder

Correct answer: B

Rationale: The short urethra in young girls predisposes them to urinary tract infections. In young girls, the proximity of the urethra to the anus and the shorter urethra compared to boys make it easier for bacteria to travel up the urinary tract, increasing the risk of infection. Increased fluid intake and frequent emptying of the bladder are actually helpful in preventing urinary tract infections by flushing out bacteria. Prostatic secretions in males are not a factor in predisposing the urinary tract to infection in children.
