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 child with a diagnosis of celiac disease is admitted to the hospital. What dietary restriction should the nurse teach the parents?

• A. Avoid dairy products
• B. Avoid gluten
• C. Avoid high-fat foods
• D. Avoid foods high in sugar

Correct answer: B

Rationale: The correct answer is B: 'Avoid gluten.' Children with celiac disease must follow a gluten-free diet to prevent symptoms and intestinal damage. Gluten is a protein found in wheat, barley, and rye, which triggers an immune response in individuals with celiac disease. Choices A, C, and D are incorrect because while some individuals with celiac disease may also have lactose intolerance or may need to manage fat or sugar intake for overall health, the primary dietary restriction for celiac disease is avoiding gluten to maintain gastrointestinal health.

3. 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 unless cyanosis is present.
• C. Ineffective sucking and swallowing may be early indications of a heart defect.
• D. Many neonates retain mucus, which can interfere with feeding for several weeks.

Correct answer: C

Rationale: Ineffective sucking and swallowing can be early signs of a heart defect like a ventricular septal defect. This is crucial information for the nurse to consider as it aligns with the infant's tentative diagnosis. Choice A is too general and does not provide specific relevance to the situation. Choice B is incorrect as inadequate sucking can indeed be significant, especially in the context of a potential heart defect. Choice D is not directly related to the potential heart defect and feeding difficulties mentioned in the scenario.

4. A child with a cardiac malformation associated with left-to-right shunting. What does this type of congenital disorder lead to primarily?

• A. Elevated hematocrit
• B. Severe growth retardation
• C. Clubbing of the fingers and toes
• D. Increased blood flow to the lungs

Correct answer: D

Rationale: Left-to-right shunting in a cardiac malformation results in increased blood flow to the lungs. This increased blood flow can lead to pulmonary hypertension and heart failure if left untreated. Elevated hematocrit (Choice A) is not a characteristic directly associated with left-to-right shunting. Severe growth retardation (Choice B) is not a typical manifestation of this type of congenital disorder. Clubbing of the fingers and toes (Choice C) is more commonly seen in conditions like chronic respiratory or cardiac diseases, not specifically with left-to-right shunting and associated cardiac malformations.

5. A group of students is reviewing information about the various types of insulin used to treat type 1 diabetes. The students demonstrate understanding of the information when they identify which of these insulins as having the longest duration.

• A. Lispro
• B. Regular
• C. NPH
• D. Glargine

Correct answer: D

Rationale: The correct answer is Glargine (Lantus) as it has the longest duration of action among the insulins listed, lasting 12 to 24 hours. Lispro (Humalog) and Regular (short-acting) insulins have shorter durations of action, typically lasting 3 to 6 hours. NPH (Neutral Protamine Hagedorn) insulin has an intermediate duration of action, lasting around 12 to 18 hours. Therefore, choices A, B, and C are incorrect in the context of insulin duration.
