A nurse is assisting with the care of a preschooler who is postoperative following tetralogy of Fallot correction. Which of the following manifestations indicates the child is possibly experiencing decreased cardiac output?
Extremities warm to touch.
Capillary refill 2 seconds.
Blood pressure 112/66 mm Hg.
Diminished pulses.
The Correct Answer is D
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.

Correct Answer is A
Explanation
Choice A rationale:
The FLACC (Face, Legs, Activity, Cry, Consolability) scale is a pain assessment tool commonly used for infants and young children who cannot verbalize their pain. It assesses different behavioral and physiological indicators of pain, such as facial expressions, leg movement, activity level, crying, and response to consoling. Given that the infant is only 18 months old, this scale is appropriate for evaluating their postoperative pain.
Choice B rationale:
The Color tool is not a recognized pain assessment tool. It's essential to use validated and standardized pain assessment scales, and the Color tool does not fit this criterion.
Choice C rationale:
The Poker Chip Tool is not typically used for pain assessment in infants. It's often used with older children to assess pain intensity using a poker chip set that corresponds to different levels of pain. However, for an 18-month-old infant, behavioral assessments like the FLACC scale would be more suitable.
Choice D rationale:
The Numeric scale involves asking the patient to rate their pain on a numerical scale, often from 0 to 10. However, this scale is not appropriate for an 18-month-old infant who is likely unable to comprehend or use numbers to express their pain. The FLACC scale provides a more comprehensive assessment of pain in non-verbal or preverbal children.
Correct Answer is C
Explanation
Choice A rationale:
Ensuring the infant bottle feeds for 45 minutes is not recommended for an infant with heart failure. Prolonged feeding sessions can lead to increased fatigue and stress on the infant's cardiovascular system, exacerbating the heart failure symptoms.
Choice B rationale:
Administering digoxin for a pulse of 70/min is not appropriate. Digoxin is commonly used in heart failure cases to improve cardiac contractility and reduce heart rate. However, giving digoxin solely based on the heart rate without considering other factors can lead to potential overdose and adverse effects.
Choice C rationale:
(Correct Choice) Allowing for frequent rest periods is crucial in the plan of care for an infant with heart failure. Infants with heart failure often experience fatigue and difficulty feeding due to compromised cardiac function. Allowing them to rest between activities helps conserve energy and supports their overall well-being.
Choice D rationale:
Maintaining the infant in a supine position is not the best choice for an infant with heart failure. While the supine position is recommended for safe sleep to reduce the risk of sudden infant death syndrome (SIDS), it may not be optimal for an infant with heart failure. An inclined position may be more suitable to alleviate potential respiratory distress.
