1. A young child has coarctation of the aorta. What does the nurse expect to identify when taking the child’s vital signs?
- A. A weak radial pulse
- B. An irregular heartbeat
- C. A bounding femoral pulse
- D. An elevated radial blood pressure
Correct answer: A
Rationale: In coarctation of the aorta, there is narrowing of the aorta leading to decreased blood flow distal to the constriction. This results in a weak or delayed femoral pulse and a relatively weaker radial pulse compared to the femoral pulse. An irregular heartbeat (choice B) is not a typical finding in coarctation of the aorta. A bounding femoral pulse (choice C) would not be expected due to the decreased blood flow beyond the constriction. An elevated radial blood pressure (choice D) is not a common characteristic of coarctation of the aorta; instead, blood pressure may be higher in the upper extremities compared to the lower extremities due to the constriction.
2. 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.
3. The nurse is planning a discussion group for parents with children who have cancer. How would the nurse describe a difference between cancer in children and adults?
- A. Most childhood cancers affect tissues rather than organs.
- B. Childhood cancers are usually localized when found.
- C. Unlike adult cancers, childhood cancers are less responsive to treatment.
- D. The majority of childhood cancers can be prevented.
Correct answer: A
Rationale: The correct answer is A. Most childhood cancers, such as leukemias and sarcomas, affect tissues rather than specific organs, unlike many adult cancers. Choice B is incorrect because childhood cancers may not always be localized when found. Choice C is incorrect as childhood cancers can be responsive to treatment, although treatment approaches may differ from adult cancers. Choice D is incorrect as the majority of childhood cancers cannot be prevented; however, certain risk factors can be managed to reduce the risk of developing cancer.
4. A child with a diagnosis of gastroenteritis is admitted to the hospital. What is the priority nursing intervention?
- A. Monitoring fluid and electrolyte balance
- B. Encouraging regular exercise
- C. Administering antipyretics
- D. Administering antibiotics
Correct answer: A
Rationale: The correct answer is monitoring fluid and electrolyte balance. Gastroenteritis is characterized by inflammation of the gastrointestinal tract leading to diarrhea and vomiting, which can result in dehydration and electrolyte imbalances. Therefore, the priority nursing intervention is to monitor and maintain the child's fluid and electrolyte balance to prevent complications. Encouraging regular exercise (Choice B) may not be appropriate initially for a child with gastroenteritis who needs rest and fluid replacement. Administering antipyretics (Choice C) is not the priority unless the child has a fever. Administering antibiotics (Choice D) is not indicated for viral gastroenteritis, which is the most common cause of the condition.
5. What should parents be taught when a 7-year-old child with a history of seizures is being discharged from the hospital?
- A. Administer antiepileptic medication as prescribed
- B. Ensure the child receives adequate sleep
- C. Restrict the child's activities to prevent seizures
- D. Teach seizure first aid to family members
Correct answer: D
Rationale: Teaching seizure first aid to family members is crucial in ensuring the child's safety during a seizure. This education empowers family members to respond effectively, protect the child from injury, and provide appropriate care. Option A is incorrect because antiepileptic medication should be administered as prescribed, not only when a seizure occurs. Option B, while important for overall health, is not specific to managing seizures. Option C is incorrect as there is no evidence that restricting activities prevents seizures, and it may negatively impact the child's quality of life without offering additional safety benefits.
