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.

Which treatment is instituted for the therapeutic management of minimal change nephrotic syndrome?
- A. corticosteroids
- B. antihypertensive agents
- C. long-term diuretics
- D. increased fluids to promote diuresis
Correct Answer: A
Rationale: Corticosteroids are the mainstay of treatment for minimal change nephrotic syndrome as they help reduce inflammation and decrease proteinuria. Antihypertensive agents are used to manage high blood pressure often associated with kidney disease but are not the primary treatment for this condition. Long-term diuretics are not typically used in the management of minimal change nephrotic syndrome as they can worsen fluid and electrolyte imbalances. Increasing fluids to promote diuresis is not recommended in this condition as it can lead to further fluid retention and edema.
A nurse is teaching a parent how to prevent accidents while caring for a 6-month-old infant. What ability should be emphasized regarding the infant's motor development?
- A. Sits up
- B. Rolls over
- C. Crawls short distances
- D. Stands while holding on to furniture
Correct Answer: B
Rationale: The correct answer is "B: Rolls over." At 6 months, most infants can roll over, which increases the risk of falls. Emphasizing the infant's ability to roll over is crucial to highlight the need for careful supervision and accident prevention. Choices A, C, and D are incorrect because sitting up, crawling short distances, and standing while holding on to furniture typically develop later in an infant's motor skills progression and are not as directly associated with an increased risk of accidents at this stage.
A child with a diagnosis of sickle cell anemia is experiencing a vaso-occlusive crisis. What is the most important nursing intervention?
- A. Administering oxygen
- B. Administering pain medication
- C. Monitoring fluid intake
- D. Encouraging physical activity
Correct Answer: B
Rationale: Administering pain medication is the most crucial nursing intervention during a vaso-occlusive crisis in sickle cell anemia. Pain management is a priority to alleviate the patient's discomfort and improve outcomes. Administering oxygen may be necessary in some cases but is not the primary intervention for vaso-occlusive crisis. Monitoring fluid intake is important in sickle cell anemia but is not the priority during a crisis situation. Encouraging physical activity is contraindicated during a vaso-occlusive crisis as it can exacerbate pain and complications.
A 2-week-old infant is admitted with a tentative diagnosis of a ventricular septal defect. The parents report that their baby has had difficulty feeding since coming home after birth. What should the nurse consider before responding?
- A. Feeding problems are common in neonates.
- B. Inadequate sucking is not significant in the absence of cyanosis.
- C. Ineffective sucking and swallowing may be early indications of a heart defect.
- D. Many neonates retain mucus, which may interfere with feeding for several weeks.
Correct Answer: C
Rationale: In this scenario, the nurse should consider that ineffective sucking and swallowing in a 2-week-old infant could be early signs of a heart defect such as a ventricular septal defect. This is crucial information as it can guide further assessment and management. Choice A is incorrect because while feeding problems can be common in neonates, in this case, the specific context of a suspected heart defect should be prioritized. Choice B is incorrect as inadequate sucking can indeed be significant, especially when considering potential underlying heart issues, regardless of the presence of cyanosis. Choice D is incorrect as while mucus retention can affect feeding, in this case, the focus should be on the possibility of a heart defect rather than a temporary issue like mucus interference.
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: Trisomy 21, also known as Down syndrome, is caused by nondisjunction, which is an error in cell division that leads to the presence of an extra chromosome 21. This additional chromosome alters the normal genetic makeup, resulting in the characteristics associated with Down syndrome. Therefore, the correct answer is nondisjunction (Choice A). Choices B, C, and D are incorrect because Trisomy 21 is not caused by X-linked recessive inheritance, genomic imprinting, or autosomal dominant inheritance. Understanding the specific genetic mechanism involved in Trisomy 21 is crucial for grasping the basis of this chromosomal disorder.
