1. A child with diabetes insipidus is being treated with vasopressin. The nurse would assess the child closely for signs and symptoms of which condition?
- A. Syndrome of inappropriate antidiuretic hormone (SIADH)
- B. Thyroid storm
- C. Cushing syndrome
- D. Vitamin D toxicity
Correct answer: A
Rationale: When a child with diabetes insipidus is treated with vasopressin, the nurse should closely monitor for signs and symptoms of Syndrome of Inappropriate Antidiuretic Hormone (SIADH). Vasopressin, also known as antidiuretic hormone, helps retain water in the body. Excessive vasopressin administration can lead to water retention, dilutional hyponatremia, and potentially result in SIADH. Choices B, C, and D are incorrect because they are not directly associated with the use of vasopressin in treating diabetes insipidus.
2. A nurse is assessing a child with suspected rotavirus infection. What clinical manifestation is the nurse likely to observe?
- A. Abdominal pain
- B. Diarrhea
- C. Constipation
- D. Vomiting
Correct answer: B
Rationale: The correct answer is B: Diarrhea. Rotavirus infection commonly presents with symptoms such as watery diarrhea, vomiting, fever, and abdominal pain. While abdominal pain and vomiting are also associated with rotavirus infection, diarrhea is a hallmark feature. Constipation is not typically seen in cases of rotavirus infection. Therefore, the most likely clinical manifestation that the nurse would observe in a child with suspected rotavirus infection is diarrhea.
3. According to Friedman's structural functional theory, what defines the family component of meeting the love and belonging needs of each member?
- A. Meeting the love and belonging needs of each member
- B. Teaching children how to function and assume adult roles in society
- C. Ensuring the family has necessary resources with appropriate allocation
- D. Involving the provision of physical care to keep the family healthy
Correct answer: A
Rationale: Friedman's structural functional theory outlines different functions of a family. The affective function, as defined by Friedman, pertains to meeting the love and belonging needs of each member. This includes emotional support, nurturing, and creating a sense of security within the family unit. Choices B, C, and D do not specifically address the affective function described in Friedman's theory. Choice B focuses on socialization and preparing children for adult roles, choice C relates to the economic function of a family, and choice D pertains to the instrumental function of providing physical care for health.
4. An infant with hypertrophic pyloric stenosis (HPS) is admitted to the pediatric unit. What does the nurse expect to find when palpating the infant’s abdomen?
- A. A distended colon
- B. Marked tenderness around the umbilicus
- C. An olive-sized mass in the right upper quadrant
- D. Rhythmic peristaltic waves in the lower abdomen
Correct answer: C
Rationale: When palpating the abdomen of an infant with hypertrophic pyloric stenosis (HPS), the nurse would expect to feel an olive-sized mass in the right upper quadrant. This finding is characteristic of HPS, where the hypertrophied pyloric muscle forms a palpable mass in the abdomen. Choices A, B, and D are incorrect. A distended colon is not a typical finding in HPS, marked tenderness around the umbilicus is not specific to this condition, and rhythmic peristaltic waves in the lower abdomen are not associated with HPS.
5. Why is it recommended that closure of the palate should be done before the age of 2 for an 11-month-old infant with a cleft palate?
- A. “After the age of 2, surgery becomes frightening and should be avoided if possible.â€
- B. “The eruption of the 2-year molars often complicates the surgical procedure.â€
- C. “As your child grows older, the palate widens, making repair more challenging.â€
- D. “Surgery should be performed before your child begins to use faulty speech patterns.â€
Correct answer: D
Rationale: It is recommended to perform palate closure surgery before the child starts using faulty speech patterns to prevent the development of speech issues that may be harder to correct later. Delaying surgery until after the age of 2 can lead to the child forming incorrect speech habits, which can be challenging to correct. Choices A, B, and C are incorrect because they do not address the specific concern related to speech development in children with cleft palates.
