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. What is the most common cause of shock (hypoperfusion) in infants and children?

• A. infection
• B. cardiac failure
• C. accidental poisoning
• D. severe allergic reaction

Correct answer: A

Rationale: Infection is the leading cause of shock in infants and children due to their heightened vulnerability to sepsis. Infants and children possess developing immune systems, rendering them more susceptible to infections that can progress to septic shock. While cardiac failure is a severe condition, it is not as commonly the primary cause of shock in this age group. Accidental poisoning, though a potential shock inducer, is less prevalent in infants and children compared to infections. Severe allergic reactions, though significant, are not as frequent as infections in precipitating shock in infants and children.

3. When explaining the occurrence of febrile seizures to a parents' class, what information should the nurse include?

• A. They may occur in minor illnesses.
• B. The cause is usually readily identified.
• C. They usually do not occur during the toddler years.
• D. The frequency of occurrence is greater in females than males.

Correct answer: A

Rationale: The correct answer is A: 'They may occur in minor illnesses.' Febrile seizures can occur even in minor illnesses, particularly in young children, and are often triggered by a rapid increase in body temperature. Choice B is incorrect because the cause of febrile seizures is not always readily identified. Choice C is incorrect as febrile seizures commonly occur in children aged 6 months to 5 years, which includes the toddler years. Choice D is incorrect as febrile seizures are slightly more common in males than females.

4. Which cardiac defects are associated with tetralogy of Fallot?

• A. Right ventricular hypertrophy, atrial and ventricular defects, and mitral valve stenosis
• B. Origin of the aorta from the right ventricle and of the pulmonary artery from the left ventricle
• C. Right ventricular hypertrophy, ventricular septal defect, pulmonic stenosis, and overriding aorta
• D. Altered connection between the pulmonary artery and the aorta, right ventricular hypertrophy, and an atrial septal defect

Correct answer: C

Rationale: Tetralogy of Fallot is characterized by a combination of four specific cardiac defects: right ventricular hypertrophy, ventricular septal defect, pulmonic stenosis, and overriding aorta. Choice A is incorrect as it includes mitral valve stenosis, which is not typically part of tetralogy of Fallot. Choice B describes transposition of the great arteries rather than tetralogy of Fallot. Choice D includes an atrial septal defect, which is not part of the classic presentation of tetralogy of Fallot.

5. What should the nurse suggest to a parent asking for advice on managing their child's earache and fever?

• A. Applying a warm compress to the affected ear
• B. Giving the child a cold drink
• C. Administering acetaminophen
• D. Taking the child to the emergency department

Correct answer: A

Rationale: The correct answer is to suggest applying a warm compress to the affected ear. This can help alleviate pain and discomfort associated with the earache. Giving a cold drink (Choice B) may not address the underlying issue and is not a recommended treatment for earaches. Administering acetaminophen (Choice C) can help reduce fever but may not directly target the earache. Taking the child to the emergency department (Choice D) is usually not necessary for a common earache unless there are severe symptoms or complications present.
