1. When teaching the parents of a child with a diagnosis of type 1 diabetes mellitus about insulin administration, what should the nurse emphasize?
- A. Rotate injection sites
- B. Administer insulin before meals
- C. Store insulin in the refrigerator
- D. Administer insulin at bedtime
Correct answer: A
Rationale: The correct answer is to rotate injection sites. This practice helps prevent lipodystrophy, a localized loss of fat tissue that can affect insulin absorption. By rotating sites, the child can avoid developing lumps or indentations in the skin where insulin is repeatedly injected. Administering insulin before meals (choice B) may be necessary for certain types of insulin but is not the priority when teaching about insulin administration. Storing insulin in the refrigerator (choice C) is important for maintaining its potency, but it is not the primary emphasis when teaching about insulin administration. Administering insulin at bedtime (choice D) may be necessary based on the child's insulin regimen but is not the primary consideration for teaching injection techniques and site rotation.
2. A healthcare professional is reviewing the laboratory report of a child with tetralogy of Fallot that indicates an elevated RBC count. What does the professional identify as the cause of the polycythemia?
- A. Low tissue oxygen needs
- B. Tissue oxygen needs
- C. Diminished iron level
- D. Hypertrophic cardiac muscle
Correct answer: B
Rationale: The correct answer is B: Tissue oxygen needs. Polycythemia occurs as the body's response to chronic hypoxia by increasing RBC production to enhance oxygen delivery. In tetralogy of Fallot, a congenital heart defect, the heart's structure causes reduced oxygen levels in the blood. This chronic hypoxia stimulates the bone marrow to produce more red blood cells, leading to an elevated RBC count. Choice A is incorrect as low blood pressure is not directly related to polycythemia in this context. Choice C, diminished iron level, is not the cause of polycythemia in tetralogy of Fallot. Choice D, hypertrophic cardiac muscle, is not the primary cause of the elevated RBC count in this case.
3. What is the priority intervention for a 10-year-old girl in a foster family?
- A. Determining if the child is being bullied at school
- B. Dealing with mixed parental expectations
- C. Establishing the child's primary caretaker
- D. Performing a comprehensive health assessment
Correct answer: D
Rationale: In a foster family setup, the priority intervention for a 10-year-old girl is to perform a comprehensive health assessment. This is crucial as children in foster care may have moved between different homes, leading to incomplete medical records. A comprehensive health assessment helps identify any health issues, track the child's growth and development, and ensure appropriate medical care. While addressing bullying at school, managing parental expectations, and establishing the primary caretaker are important considerations, the immediate priority for the child's well-being and holistic care is to conduct a thorough health assessment.
4. Congenital heart defects have traditionally been divided into acyanotic or cyanotic defects. Based on the nurse’s knowledge of congenital heart defects, this system in clinical practice is
- A. helpful because it explains the hemodynamics involved
- B. helpful because children with cyanotic defects are easily identified
- C. problematic because cyanosis is rarely present in children
- D. problematic because children with acyanotic heart defects may develop cyanosis
Correct answer: D
Rationale: The classification system of congenital heart defects into acyanotic or cyanotic defects is problematic because children with acyanotic heart defects may develop cyanosis, complicating the differentiation. Cyanosis can occur in some acyanotic defects due to various reasons such as right-to-left shunting or decreased pulmonary blood flow, making the classification based solely on cyanosis misleading. Choice A is incorrect because while the classification may involve hemodynamics, the main issue lies in the potential for acyanotic defects to develop cyanosis. Choice B is incorrect as the ease of identifying children with cyanotic defects does not address the main problem with the classification system. Choice C is also incorrect as the presence of cyanosis is not the only factor determining the classification's validity.
5. What is the most common cause of shock (hypoperfusion) in infants and children?
- A. infection
- B. cardiac failure
- C. accidental poisoning
- D. severe allergic reaction
Correct answer: A
Rationale: Infection is the leading cause of shock in infants and children due to their heightened vulnerability to sepsis. Infants and children possess developing immune systems, rendering them more susceptible to infections that can progress to septic shock. While cardiac failure is a severe condition, it is not as commonly the primary cause of shock in this age group. Accidental poisoning, though a potential shock inducer, is less prevalent in infants and children compared to infections. Severe allergic reactions, though significant, are not as frequent as infections in precipitating shock in infants and children.
