Correct Answer is A

Explanation

- A: A heart rate greater than 60/min indicates that the transcutaneous pacing is effectively maintaining a heart rate within a normal range, which is crucial for adequate cardiac output and systemic perfusion.
- B: While 2+ pedal pulses indicate good peripheral perfusion, they do not directly reflect the effectiveness of transcutaneous pacing in treating complete heart block.
- C: Pacer spikes should appear before the QRS complex to show that the pacing stimulus is being delivered appropriately. Spikes after the QRS complex suggest that the pacing is not capturing the heart effectively.
- D: Distended jugular veins would be more indicative of heart failure or fluid overload and do not directly relate to the effectiveness of pacing therapy.

A. Flat anterior fontanel B. Oliguria C. Oral intake of 4 oz every 3 hr D. Capillary refill 4 seconds

Correct Answer is C

Explanation

A. A flat anterior fontanel can indicate dehydration in infants, so this finding does not indicate effective treatment.

B. Oliguria, or decreased urine output, is a sign of dehydration and would not indicate effective treatment.

C. Oral intake of 4 oz every 3 hours indicates that the infant is able to drink fluids and is likely rehydrated, indicating effective treatment.

D. A capillary refill of 4 seconds is prolonged and can indicate poor perfusion, which is not indicative of effective treatment for dehydration.
