A nurse is preparing to administer recommended immunizations to an 11-year-old child who is up-to-date with current immunizations. Which of the following immunizations should the nurse plan to administer?

Choice A rationale:
Implementing fluid restrictions is not recommended for a child with diabetic ketoacidosis (DKA). DKA is characterized by dehydration and electrolyte imbalances, and fluid replacement is a crucial aspect of its management. Restricting fluids could worsen dehydration and hinder the correction of metabolic imbalances.
Choice B rationale:
(Correct Choice) Monitoring vital signs every 8 hours is an important intervention for a school-age child with DKA. Vital signs, including heart rate, respiratory rate, blood pressure, and temperature, provide valuable information about the child's overall condition, fluid status, and response to treatment. More frequent monitoring might be necessary during the acute phase of DKA.
Choice C rationale:
Initiating continuous cardiac monitoring is not typically indicated for a school-age child with DKA. While DKA can have effects on the cardiovascular system, continuous cardiac monitoring is reserved for more critical situations where immediate changes in heart rhythm need to be detected.
Choice D rationale:
Administering subcutaneous insulin 30 minutes before meals is not appropriate for a child with DKA. In DKA management, insulin is typically administered intravenously to achieve more precise control over blood glucose levels. Subcutaneous insulin might not provide the rapid and consistent action needed to address the acute hyperglycemia and metabolic acidosis in DKA.

Choice A rationale:
Extremities warm to the touch. This manifestation is not indicative of decreased cardiac output. Warm extremities suggest adequate peripheral perfusion and circulation. In a child with decreased cardiac output, the body might attempt to shunt blood away from the extremities to prioritize vital organs, leading to cooler extremities.
Choice B rationale:
Capillary refill 2 seconds. A capillary refill time of 2 seconds is within the normal range for a preschool-aged child. This quick capillary refill suggests adequate circulation and is not a sign of decreased cardiac output. Prolonged capillary refill time might be indicative of poor peripheral perfusion.
Choice C rationale:
Blood pressure 112/66 mm Hg. While a blood pressure of 112/66 mm Hg might be within the normal range for a preschooler, it is not the most reliable indicator of decreased cardiac output. Blood pressure can be influenced by various factors, and a seemingly normal blood pressure does not rule out decreased cardiac output if other manifestations are present.
Choice D rationale:
Diminished pulses. This is the correct choice. Diminished or weak pulses are indicative of decreased cardiac output. Inadequate blood volume being pumped by the heart can lead to reduced peripheral perfusion, resulting in diminished pulses. This sign is important in assessing the child's cardiovascular status postoperatively, especially after a corrective procedure for tetralogy of Fallot.
