A 9-week-old infant is scheduled for cleft lip repair. Which information is most important for the nurse to convey to the surgeon before transporting the infant to the surgical suite?

A. Red blood cell count of 2.3 million/mm³

B. White blood cell count of 10,000/mm³

C. Weight gain of 2 pounds since birth

D. Urine specific gravity is 1.011

Correct Answer: A
Rationale: The correct answer is A because a low red blood cell count may indicate anemia, which could pose risks during surgery. Anemia can affect oxygen delivery to tissues, impacting wound healing and overall surgical outcomes. The other options, such as white blood cell count, weight gain, and urine specific gravity, are less critical for immediate surgical considerations. White blood cell count is more related to infection risk postoperatively rather than immediate surgical risk. Weight gain reflects good overall growth but does not impact the immediate surgical situation. Urine specific gravity is more indicative of hydration status rather than immediate surgical risk.

A 5-year-old child with leukemia is receiving chemotherapy. The nurse notes that the child’s white blood cell count is low. What is the nurse’s priority intervention?

• A. Administer antibiotics as prescribed
• B. Place the child in protective isolation
• C. Encourage the child to eat a balanced diet
• D. Teach the parents about infection prevention

Correct Answer: B
Rationale: The priority intervention for a 5-year-old child with leukemia receiving chemotherapy and having a low white blood cell count is to place the child in protective isolation. This intervention helps reduce the risk of infection, which is crucial in this immunocompromised state. Protective isolation aims to limit the child's exposure to pathogens and promote their safety during a period of increased vulnerability to infections.

A 9-year-old child with a history of type 1 diabetes is brought to the clinic for a check-up. The nurse notes that the child's hemoglobin A1c is 8.5%. What is the most appropriate action for the nurse to take?

• A. Increase the child’s insulin dose
• B. Review the child’s dietary habits and insulin administration technique
• C. Discuss the possibility of switching to oral hypoglycemics
• D. Schedule a follow-up appointment in three months

Correct Answer: B
Rationale: A hemoglobin A1c of 8.5% indicates suboptimal diabetes control. The most appropriate action for the nurse in this scenario is to review the child’s dietary habits and insulin administration technique. This approach can help identify potential areas for improvement and optimize diabetes management, aiming to lower the hemoglobin A1c levels towards the target range. Increasing the child’s insulin dose (Choice A) without addressing dietary habits and administration technique may not lead to better control and can increase the risk of hypoglycemia. Switching to oral hypoglycemics (Choice C) is not appropriate for type 1 diabetes management. Scheduling a follow-up appointment in three months (Choice D) without intervening to improve diabetes control is not the best immediate action.

A child who is admitted to the hospital with anemia is anxious, fearful, and hyperventilating. The nurse anticipates the child developing which acid-base imbalance?

• A. Metabolic acidosis
• B. Respiratory acidosis
• C. Respiratory alkalosis
• D. Metabolic alkalosis

Correct Answer: C
Rationale: In this scenario, the child is hyperventilating, which leads to excessive loss of carbon dioxide. This loss of carbon dioxide causes respiratory alkalosis due to a decrease in the partial pressure of carbon dioxide in the blood. Therefore, the correct answer is respiratory alkalosis. Choices A, B, and D are incorrect. Metabolic acidosis is characterized by a decrease in pH and bicarbonate levels due to conditions like kidney disease. Respiratory acidosis is caused by retention of carbon dioxide, leading to an increase in the partial pressure of carbon dioxide. Metabolic alkalosis results from a loss of acid or an increase in bicarbonate levels.

When a 3-year-old boy asks a nurse why his baby sister is eating his mommy’s breast, how should the nurse respond? (Select the response that does not apply.)

• A. Remind him that his mother breastfed him too
• B. Clarify that breastfeeding is the mother’s choice
• C. Reassure the older brother that it does not hurt his mother
• D. Explain that newborns get milk from their mothers in this way

Correct Answer: A
Rationale: In this scenario, the nurse should avoid reminding the older sibling about his own breastfeeding experience as it does not directly address the question posed by the boy. Providing simple explanations about breastfeeding and newborn feeding patterns helps the older sibling understand the natural process without bringing up personal experiences. Choice B is correct because clarifying that breastfeeding is the mother's choice helps the older sibling understand the concept of personal decisions. Choice C is appropriate as reassuring the older brother that it does not hurt his mother addresses a common concern children may have. Choice D is also suitable as it explains in simple terms how newborns receive milk from their mothers.
