1. Which statement by a school-aged client going to summer camp indicates the best understanding of the mode of transmission of Lyme disease?

A. I'll cover my mouth with a wet cloth if there's too much dust blowing.
B. Cuts and scrapes need to be washed out and covered right away.
C. I'm not going to swim where the water is standing still or feels too hot.
D. I have to wear long sleeves and pants when we're hiking around the pond.

Correct answer: D

Rationale: The correct answer is D. Wearing long sleeves and pants helps prevent tick bites, which can transmit Lyme disease. Ticks carrying Lyme disease are often found in wooded or grassy areas, so covering exposed skin can reduce the risk of being bitten by an infected tick. Choices A, B, and C do not address the specific mode of transmission of Lyme disease through tick bites, making them incorrect.

2. A 10-year-old child is admitted with diabetic ketoacidosis (DKA). Which laboratory value should the practical nurse (PN) anticipate?

A. Elevated blood glucose.
B. Decreased serum ketones.
C. Low urine glucose.
D. High bicarbonate levels.

Correct answer: A

Rationale: In a case of diabetic ketoacidosis (DKA), the primary feature is elevated blood glucose levels due to insulin deficiency. Additionally, ketones are increased in the blood and urine. Bicarbonate levels are usually low because of the metabolic acidosis that accompanies DKA. Therefore, the practical nurse should anticipate elevated blood glucose levels as a characteristic laboratory finding in a child admitted with DKA. Choice B is incorrect because serum ketones are increased in DKA. Choice C is incorrect because in DKA, urine glucose is typically high due to spillage of glucose into the urine. Choice D is incorrect because bicarbonate levels are usually low in DKA, not high.

3. A 5-year-old child is brought to the emergency department with severe abdominal pain and vomiting. The childâ€™s parent reports that the pain started suddenly and is located in the lower right abdomen. What should the nurse do first?

A. Administer pain medication
B. Notify the healthcare provider immediately
C. Start an IV line for fluid administration
D. Obtain a complete blood count

Correct answer: B

Rationale: The correct answer is to notify the healthcare provider immediately. The child's presentation of sudden, severe abdominal pain in the lower right abdomen is highly concerning for appendicitis, a medical emergency. Promptly notifying the healthcare provider is crucial for further evaluation and management. Administering pain medication as the first action might mask symptoms and delay diagnosis. Starting an IV line for fluid administration and obtaining a complete blood count are important interventions but should come after healthcare provider notification.

4. While auscultating the lung sounds of a 5-year-old Chinese boy who recently completed antibiotic therapy for pneumonia, the nurse notices symmetrical, round, bruise-like blemishes on his chest. What action is best for the nurse to take?

A. Identify the antibiotics used for treating the pneumonia.
B. Inquire about the use of alternative treatment methods.
C. Ask the parents if the child has been in a recent accident.
D. Report suspected child abuse to the authorities.

Correct answer: B

Rationale: Inquiring about the use of alternative treatment methods is essential to understand cultural practices and provide holistic care. It allows the nurse to gather more information about the blemishes and potentially uncover traditional or alternative healing approaches that the family may have used. This approach demonstrates cultural sensitivity and a comprehensive assessment before making assumptions or taking further actions. Identifying the antibiotics used for treating pneumonia (Choice A) is not immediately necessary in this context as the focus is on the blemishes. Asking about a recent accident (Choice C) assumes a traumatic cause without evidence. Reporting suspected child abuse (Choice D) is premature without further assessment or evidence of abuse.

5. The nurse is conducting an admission assessment of an 11-month-old infant with CHF who is scheduled for repair of restenosis of coarctation of the aorta that was repaired 4 days after birth. Findings include blood pressure higher in the arms than the lower extremities, pounding brachial pulses, and slightly palpable femoral pulses. What pathophysiologic mechanisms support these findings?

A. The aortic semilunar valve obstructs blood flow into the systemic circulation
B. The lumen of the aorta reduces the volume of the blood flow to the lower extremities
C. The pulmonic valve prevents adequate blood volume into the pulmonary circulation
D. An opening in the atrial septum causes a murmur due to a turbulent left to right shunt

Correct answer: B

Rationale: The findings are consistent with coarctation of the aorta, where narrowing of the aorta leads to decreased blood flow to the lower extremities. This results in higher blood pressure in the arms compared to the lower extremities, pounding brachial pulses, and slightly palpable femoral pulses. Choices A, C, and D are incorrect because they do not align with the pathophysiological mechanisms of coarctation of the aorta, which specifically involves narrowing of the aortic lumen reducing blood flow to the lower extremities.
