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 A
Explanation
Choice A rationale:
Obtain the specimen by swabbing the infant's rectum using a sterile culture swab. This is the correct choice. When collecting a stool specimen from an infant, the rectal swab method is commonly used. A sterile culture swab helps prevent contamination and ensures accurate results for detecting the presence of ova and parasites in the stool.
Choice B rationale:
Place a urine collection device on the infant until the specimen is obtained. This choice is not appropriate for collecting a stool specimen. A urine collection device is used for collecting urine, not stool. The specimen for ova and parasites needs to be taken directly from the rectum or diaper to accurately identify any infestations.
Choice C rationale:
Transfer the specimen to the collection container using povidone-iodine-soaked gauze. While povidone-iodine is an antiseptic, it is not typically used to transfer stool specimens. Using a sterile swab or a clean, dry container is more suitable for collecting and transporting stool samples to the lab.
Choice D rationale:
Maintain the specimen at room temperature after collection until it is transferred to the lab. Stool specimens for ova and parasites usually require refrigeration to prevent the degradation and growth of potential pathogens. Room temperature might lead to the overgrowth of bacteria and parasites, affecting the accuracy of test results.
