A nurse is preparing to check the capillary blood glucose level of a school-age child. Which of the following actions should the nurse plan to take?

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.

Choice A rationale:
This medication can cause ringing in the ears (Choice A) is not a common side effect of amoxicillin. Ringing in the ears (tinnitus) is not typically associated with the use of this antibiotic.
Choice B rationale:
This medication can cause muscle pain (Choice B) is not a common side effect of amoxicillin. Muscle pain is not among the usual adverse reactions associated with its use.
Choice C rationale:
This medication can cause loose stools (Choice C) is a relevant side effect of amoxicillin. Antibiotics, including amoxicillin, can disrupt the normal balance of gut bacteria, potentially leading to gastrointestinal disturbances such as diarrhea or loose stools.
Choice D rationale:
This medication can cause blurred vision (Choice D) is not a common side effect of amoxicillin. Blurred vision is not a typical adverse effect associated with the use of this antibiotic.
