Nursing Elites

1. A nurse is teaching the parents of a toddler about the signs and symptoms of lead poisoning. Which symptom should the nurse emphasize?

• A. Abdominal pain
• B. Constipation
• C. Irritability
• D. Frequent urination

Correct answer: C

Rationale: Irritability is a significant symptom of lead poisoning in toddlers and should be emphasized to parents. Lead poisoning can manifest with various symptoms, but irritability is particularly common in children exposed to lead. Abdominal pain (Choice A) is not a typical symptom of lead poisoning in toddlers. While constipation (Choice B) can occur, it is less specific and less common than irritability. Frequent urination (Choice D) is not a typical symptom associated with lead poisoning in toddlers and is less relevant for parents to recognize in this context.

2. Before starting kindergarten, the child should receive boosters of which primary immunizations to ensure ongoing protection?

• A. IPV, HepB, Td.
• B. DTaP, HepB, Td.
• C. MMR, DTaP, Hib.
• D. DTaP, IPV, MMR.

Correct answer: D

Rationale: Before starting kindergarten, the child should receive boosters of DTaP, IPV, and MMR. DTaP provides protection against diphtheria, tetanus, and pertussis, IPV protects against polio, and MMR immunization covers measles, mumps, and rubella. These boosters are essential to maintain immunity and protect the child from these diseases as they enter school. Choices A, B, and C are incorrect because they do not include the recommended boosters for kindergarten entry and may leave the child susceptible to certain infections.

3. When developing the plan of care for a child with burns requiring fluid replacement therapy, what information would the nurse expect to include?

• A. Administration of colloid initially followed by a crystalloid
• B. Determination of fluid replacement based on the type of burn
• C. Administration of most of the volume during the first 8 hours
• D. Monitoring of hourly urine output to achieve less than 1 mL/kg/hr

Correct answer: C

Rationale: The correct answer is C. In fluid replacement therapy for burns, the majority of the volume should be administered within the first 8 hours to prevent shock and maintain perfusion. Choice A is incorrect because crystalloids are typically administered first in fluid resuscitation for burns. Choice B is incorrect as fluid replacement in burn patients is primarily determined by the extent of the burn injury rather than the type of burn. Choice D is incorrect as the goal for hourly urine output in burn patients is generally higher, aiming for 1-2 mL/kg/hr in children to ensure adequate renal perfusion and prevent dehydration.

4. The nurse is assisting low-income families to access health care. The nurse is aware that, in today's society, this most accurately defines the diversity of a modern family.

• A. A family consists of parents and their offspring living together.
• B. A family is whatever the child and family say it is.
• C. A family is two or more people related or unrelated who are living together.
• D. A family is two or more genetically related persons living together with separate roles.

Correct answer: B

Rationale: Given the diversity of families in today's society, some believe that family should be defined as whatever the child and family say it is.

5. 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.
