1. What should the nurse include in the care plan for a 6-month-old infant admitted with a diagnosis of respiratory syncytial virus (RSV)?
- A. Provide small, frequent feedings
- B. Administer antibiotics
- C. Maintain strict isolation
- D. Elevate the head of the bed
Correct answer: D
Rationale: Elevating the head of the bed is crucial in the care plan for an infant with RSV as it helps improve breathing by facilitating better airflow and drainage of secretions. This position can also enhance comfort and reduce respiratory distress. Providing small, frequent feedings (Choice A) is generally beneficial for infants but is not specific to managing RSV. Administering antibiotics (Choice B) is not indicated for RSV as it is caused by a virus, and antibiotics are ineffective against viral infections. Maintaining strict isolation (Choice C) is important to prevent the spread of contagious infections but is not a direct intervention for improving the infant's respiratory status in RSV.
2. A nurse is reviewing the laboratory report of a child with tetralogy of Fallot that indicates an elevated RBC count. What does the nurse identify as the cause of the polycythemia?
- A. Low tissue oxygen needs
- B. Tissue oxygen needs
- C. Diminished iron levels
- D. Hypertrophic cardiac muscle
Correct answer: B
Rationale: The correct answer is B: Tissue oxygen needs. Polycythemia occurs in response to chronic hypoxia, leading the body to increase red blood cell production to enhance oxygen delivery. In tetralogy of Fallot, a congenital heart defect that results in reduced oxygen levels in the blood, the body compensates by producing more red blood cells. Choice A is incorrect as low tissue oxygen needs would not trigger polycythemia. Choice C, diminished iron levels, is not the cause of polycythemia in this case. Choice D, hypertrophic cardiac muscle, is unrelated to the pathophysiology of polycythemia in tetralogy of Fallot.
3. Why is the infant scheduled to receive the intramuscular polio vaccine instead of the oral vaccine, as asked by the parents?
- A. The American Academy of Pediatrics recommends the intramuscular vaccine because it is safer.
- B. Both vaccines produce the same results and are equally safe, according to consensus.
- C. The intramuscular vaccine is preferred over the oral vaccine due to cost considerations, unless contraindicated.
- D. The U.S. Centers for Disease Control and Prevention recommends the intramuscular vaccine unless the infant or a family member is immunocompromised.
Correct answer: A
Rationale: The American Academy of Pediatrics recommends the intramuscular polio vaccine over the oral vaccine due to its superior safety profile. Intramuscular administration ensures better immunogenicity and protection against poliovirus. Choice B is incorrect as the intramuscular vaccine is preferred for safety reasons. Choice C is incorrect because the recommendation is based on safety, not cost. Choice D is incorrect as the CDC recommendation is not solely based on immunocompromised status but rather on the overall safety and efficacy of the vaccine.
4. When teaching a group of parents in the daycare center about accident prevention, the nurse explains that young toddlers are prone to injuries from falls. When receiving feedback, the nurse identifies that more teaching is needed when one parent states, 'I will:'
- A. keep medications in a medicine cabinet.
- B. have secured gates at entrances to staircases.
- C. move our child to a regular bed by the age of three.
- D. buy shoes that fasten with Velcro rather than laces.
Correct answer: C
Rationale: The correct answer is C. Moving a child to a regular bed by the age of three can increase the risk of falls as young toddlers may not have the motor skills to safely navigate a larger bed. This indicates a need for more teaching on safety measures. Choices A, B, and D are all appropriate safety measures that can help prevent accidents and injuries in young children. Keeping medications in a medicine cabinet, having secured gates at entrances to staircases, and choosing shoes that fasten with Velcro instead of laces are all good practices to ensure a safe environment for toddlers.
5. An 8-year-old child with the diagnosis of meningitis is to have a lumbar puncture. What should the nurse explain is the purpose of this procedure?
- A. To measure the pressure of cerebrospinal fluid
- B. To obtain a sample of cerebrospinal fluid for analysis
- C. To relieve intracranial pressure
- D. To assess the presence of infection in the spinal fluid
Correct answer: B
Rationale: The primary purpose of a lumbar puncture is to obtain a sample of cerebrospinal fluid for analysis. This sample helps in diagnosing conditions such as meningitis by evaluating the presence of pathogens or abnormalities in the cerebrospinal fluid. Measuring the pressure of cerebrospinal fluid (Choice A) is not the main objective of a lumbar puncture, although it can be done during the procedure. Relieving intracranial pressure (Choice C) is not the direct purpose of a lumbar puncture, as other interventions are typically used for this purpose. Assessing the presence of infection in the spinal fluid (Choice D) is related to the overall goal of obtaining a sample for analysis, making it a secondary outcome of the procedure.
