Nursing Elites

1. A 2-year-old child is admitted to the hospital with a diagnosis of Kawasaki disease. What is the primary goal of therapy during the acute phase?

• A. Preventing coronary artery aneurysms
• B. Reducing fever
• C. Improving cardiac function
• D. Preventing dehydration

Correct answer: A

Rationale: The primary goal of therapy during the acute phase of Kawasaki disease is to prevent coronary artery aneurysms. Kawasaki disease is characterized by systemic vasculitis and the most serious complication is the development of coronary artery aneurysms. While reducing fever and improving cardiac function are important aspects of managing Kawasaki disease, the primary focus in the acute phase is to prevent the development of coronary artery aneurysms. Preventing dehydration is also essential but not the primary goal in managing Kawasaki disease.

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 most common cause of shock in infants and children due to their increased susceptibility to sepsis. Infants and children have underdeveloped immune systems, making them more prone to infections that can lead to septic shock. While cardiac failure is a serious condition, it is not the most common cause of shock in this population. Accidental poisoning, though dangerous, is less common than infection in causing shock in infants and children. Severe allergic reactions can lead to anaphylactic shock, but they are not as prevalent as infections in causing shock in this age group.

3. What definitive diagnostic procedure does the nurse expect to be used to confirm the diagnosis of Hirschsprung disease in a 1-month-old infant?

• A. Colonoscopy
• B. Rectal biopsy
• C. Multiple saline enemas
• D. Fiberoptic nasoenteric tube

Correct answer: B

Rationale: Rectal biopsy is the definitive diagnostic procedure for Hirschsprung disease in infants. This procedure reveals the absence of ganglion cells in the affected bowel segment, which is a hallmark of Hirschsprung disease. Colonoscopy (Choice A) is not typically used for diagnosing Hirschsprung disease due to the risk of not accurately reaching the affected segment. Multiple saline enemas (Choice C) are not used to confirm the diagnosis of Hirschsprung disease. Fiberoptic nasoenteric tube (Choice D) is not a standard diagnostic procedure for Hirschsprung disease and does not provide the necessary information to confirm the absence of ganglion cells in the affected bowel segment.

4. What explanation should be given to a parent about the purpose of a tetanus toxoid injection for their child?

• A. Passive immunity is conferred for life.
• B. Long-lasting active immunity is conferred.
• C. Lifelong active natural immunity is conferred.
• D. Passive natural immunity is conferred temporarily.

Correct answer: B

Rationale: The correct answer is B: 'Long-lasting active immunity is conferred.' Tetanus toxoid injection provides long-lasting active immunity by stimulating the body to produce its own antibodies. Choice A is incorrect because tetanus toxoid injection does not provide passive immunity. Choice C is incorrect because the immunity conferred by the vaccine is not natural but artificially induced. Choice D is incorrect as the immunity provided by the tetanus toxoid injection is active, not passive.

5. A healthcare professional is teaching parents about why most children should be immunized against varicella (chickenpox) and why some receiving specific medications should not. Which medication should be included in the discussion?

• A. Insulin
• B. Steroids
• C. Antibiotics
• D. Anticonvulsants

Correct answer: B

Rationale: The correct answer is B: Steroids. Children receiving steroids should not receive the varicella vaccine as it can increase the risk of severe infection due to the immunosuppressive effects of steroids. Insulin (Choice A) is not a medication that contraindicates varicella vaccination. Antibiotics (Choice C) and anticonvulsants (Choice D) are also not medications that would impact the decision to immunize against varicella.
