Nursing Elites

1. When describing urticaria, what would an instructor include?

• A. It is a type IV hypersensitivity reaction.
• B. Histamine release leads to vasodilation.
• C. Wheals appear first followed by erythema.
• D. The nonpruritic rash blanches with pressure.

Correct answer: B

Rationale: The correct answer is B. Urticaria is a type I hypersensitivity reaction where histamine release leads to vasodilation and the formation of characteristic wheals. Choice A is incorrect as urticaria is associated with type I hypersensitivity, not type IV. Choice C is incorrect because in urticaria, erythema typically appears before the development of wheals. Choice D is incorrect as urticaria is typically pruritic and does not blanch with pressure.

2. A parent and 4-year-old child who recently emigrated from Colombia arrive at the pediatric clinic. The child has a temperature of 102°F, is irritable, and has a runny nose. Inspection reveals a rash and several small, red, irregularly shaped spots with blue-white centers in the mouth. What illness does the nurse suspect the child has?

• A. Measles
• B. Chickenpox
• C. Fifth disease
• D. Scarlet fever

Correct answer: A

Rationale: The nurse should suspect measles in this child. The presence of a high fever, irritability, runny nose, rash, and Koplik spots (small, red spots with blue-white centers in the mouth) are classic signs of measles. Measles is a highly contagious viral illness that can lead to serious complications if not managed promptly. Chickenpox (choice B) presents with a different rash pattern and does not typically involve Koplik spots. Fifth disease (choice C) and scarlet fever (choice D) also have distinct clinical presentations and are not characterized by the specific symptoms described in this case.

3. 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. Lead exposure can lead to behavioral changes, including irritability, which is crucial for parents to recognize. While abdominal pain and constipation can occur in lead poisoning, they are not as specific or prominent as irritability. Frequent urination is not typically associated with lead poisoning in toddlers, making it a less relevant symptom to emphasize. By highlighting irritability, parents can be better equipped to identify potential signs of lead poisoning in their toddler.

4. A child is diagnosed with atopic dermatitis. Which laboratory test would the nurse expect the child to undergo to provide additional evidence for this condition?

• A. Erythrocyte sedimentation rate
• B. Potassium hydroxide prep
• C. Wound culture
• D. Serum immunoglobulin E (IgE) level

Correct answer: D

Rationale: The correct answer is D: Serum immunoglobulin E (IgE) level. An elevated serum IgE level is commonly associated with atopic dermatitis, reflecting an allergic response. Choice A, erythrocyte sedimentation rate, is a nonspecific test for inflammation and not specific to atopic dermatitis. Choice B, potassium hydroxide prep, is used to diagnose fungal infections like tinea versicolor, not atopic dermatitis. Choice C, wound culture, is not typically indicated for the diagnosis of atopic dermatitis as it is a chronic inflammatory skin condition rather than an infectious process.

5. When administering IV fluids to a dehydrated infant, what intervention is most important at this time?

• A. Continuing the prescribed flow rate
• B. Monitoring the intravenous drop rate
• C. Calculating the total necessary intake
• D. Maintaining the fluid at body temperature

Correct answer: B

Rationale: Monitoring the intravenous drop rate is crucial when administering IV fluids to ensure that the correct amount of fluids is delivered to the dehydrated infant. Choice A assumes the initial rate is correct without ongoing assessment. Choice C, while important, does not address the immediate need for monitoring the infusion rate. Choice D, maintaining the fluid at body temperature, is essential for comfort but is not as critical as ensuring the correct fluid delivery rate. By monitoring the intravenous drop rate, healthcare providers can adjust the flow as needed to prevent overhydration or underhydration, helping to manage the infant's fluid balance effectively.
